Now, researchers from Chalmers University of Technology, Sweden, present a totally new way to clean contaminated water, through an electrochemical process. The results are published in the scientific journal Nature Communications. ​​​</b></p><div><span style="background-color:initial">“Our results have really exceeded the expectations we had when we started with the technique,” says the research leader Björn Wickman, from Chalmers’ Department of Physics. “Our new method makes it possible to reduce the mercury content in a liquid by more than 99%. This can bring the water well within the margins for safe human consumption.” </span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div>According to the World Health Organisation (WHO), mercury is one the most harmful substances for human health. It can influence the nervous system, the development of the brain, and more. It is particularly harmful for children and can also be transmitted from a mother to a child during pregnancy. Furthermore, mercury spreads very easily through nature, and can enter the food chain. Freshwater fish, for example, often contain high levels of mercury. </div> <div><br /></div> <div>In the last two years, Björn Wickman and Cristian Tunsu, researcher at the Department of Chemistry and Chemical Engineering at Chalmers, have studied an electrochemical process for cleaning mercury from water. Their method works via extracting the heavy metal ions from water by encouraging them to form an alloy with another metal. </div> <div><br /></div> <div>“Today, removing low, yet harmful, levels of mercury from large amounts of water is a major challenge. Industries need better methods to reduce the risk of mercury being released in nature,” says Björn Wickman. </div> <div><br /></div> <img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Vattenrening_labbsetup1_webb.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;background-color:initial" /><div>Their new method involves a metal plate – an electrode – that binds specific heavy metals to it. The electrode is made of the noble metal platinum, and through an electrochemical process it draws the toxic mercury out of the water to form an alloy of the two. In this way, the water is cleaned of the mercury contamination. The alloy formed by the two metals is very stable, so there is no risk of the mercury re-entering the water. </div> <div><br /></div> <div>“An alloy of this type has been made before, but with a totally different purpose in mind. This is the first time the technique with electrochemical alloying has been used for decontamination purposes,” says Cristian Tunsu.</div> <div><br /></div> <div>One strength of the new cleaning technique is that the electrode has a very high capacity. Each platinum atom can bond with four mercury atoms. Furthermore, the mercury atoms do not only bond on the surface, but also penetrate deeper into the material, creating thick layers. This means the electrode can be used for a long time. After use, it can be emptied in a controlled way. Thereby, the electrode can be recycled, and the mercury disposed of in a safe way. A further positive for this process is that it is very energy efficient.</div> <div><br /></div> <div>“Another great thing with our technique is that it is very selective. Even though there may be many different types of substance in the water, it just removes the mercury. Therefore, the electrode doesn’t waste capacity by unnecessarily taking away harmless substances from the water,” says Björn Wickman. </div> <div><br /></div> <div>Patenting for the new method is being sought, and in order to commercialise the discovery, the company Atium has been setup. The new innovation has already been bestowed with a number of prizes and awards, both in Sweden and internationally. The research and the colleagues in the company have also had a strong response from industry. ​ </div> <div><br /></div> <div>“We have already had positive interactions with a number of interested parties, who are keen to test the method. Right now, we are working on a prototype which can be tested outside the lab under real-world conditions.”</div> <div><br /></div> <div>Text: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se​</a> </div> <div>and Joshua Worth, <a href="mailto:%20joshua.worth@chalmers.se"> joshua.worth@chalmers.se ​</a><br /></div> <div><br /></div> <div>Read the article, <a href="https://www.nature.com/articles/s41467-018-07300-z">“Effective removal of mercury from aqueous streams via electrochemical alloy formation on platinum”​</a> in Nature Communications.</div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Vattenrening_Bjorn_Wickman_Cristian_Tunsu_portratt_750x340_NY.jpg" alt="" style="margin:5px" />​<span style="background-color:initial">Björn Wickman and Cristian Tunsu</span><span style="background-color:initial"> ​are pr</span><span style="background-color:initial">esenting a new and effective way of cleaning mercury from water.

Heavy metals are toxic for all living organisms in the food chain. According to the WHO, mercury is one of the most dangerous substances for human health, influencing our nervous system, brain development and more. The substance is especially dangerous for children and unborn babies. </div> <div>Today there are strict regulations concerning the management of toxic heavy metals to hinder their spread in nature. But there are many places worldwide which are already contaminated, and they can be transported in rain or in the air. This results in certain environments where heavy metals can become abundant, for example fish in freshwater sources. In industries where heavy metals are used, there is a need for better methods of recycling, cleaning and decontamination of the affected water. <span style="background-color:initial">​</span></div></div> <div><h3 class="chalmersElement-H3" style="font-family:&quot;open sans&quot;, sans-serif">For more information</h3> <div><span style="font-weight:700"><a href="/en/Staff/Pages/Björn-Wickman.aspx">Björn Wickman​</a></span>, Assistant Professor, Department of Physics, Chalmers University of Technology, +46 31 772 51 79, <a href="mailto:bjorn.wickman@chalmers.se">bjorn.wickman@chalmers.se​</a></div> <div><span style="font-weight:700"><a href="/en/staff/Pages/tunsu.aspx">Cristian Tunsu</a></span>,  Post Doc, Department of Chemistry and Chemical Engineering​, <span style="background-color:initial">Chalmers University of Technology, +46 </span><span style="background-color:initial">31 772 29 45, <a href="mailto:tunsu@chalmers.se">tunsu@chalmers.se</a></span></div></div> <div><div><div><span style="background-color:initial"></span></div></div></div>Wed, 21 Nov 2018 07:00:00 +0100https://www.chalmers.se/en/departments/physics/news/Pages/How-gold-can-melt-at-room-temperature-.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/How-gold-can-melt-at-room-temperature-.aspxHow to melt gold at room temperature<p><b>​When the tension rises, unexpected things can happen – not least when it comes to gold atoms. Researchers from, among others, Chalmers University of Technology, have now managed, for the first time, to make the surface of a gold object melt at room temperature.​</b></p><div><div><div>​<span style="background-color:initial">Ludvig de Knoop, from Chalmers’ Department of Physics, placed a small piece of gold in an electron microscope. Observing it at the highest level of magnification and increasing the electric field step-by-step to extremely high levels, he was interested to see how it influenced the gold atoms.</span></div> <div>It was when he studied the atoms in the recordings from the microscope, that he saw something exciting. The surface layers of gold had actually melted – at room temperature.</div> <div><br /></div> <div>&quot;I was really stunned by the discovery. This is an extraordinary phenomenon, and it gives us new, foundational knowledge of gold,” says Ludvig de Knoop.</div> <div><br /></div> <div>What happened was that the gold atoms became excited. Under the influence of the electric field, they suddenly lost their ordered structure and released almost all their connections to each other.</div> <div>Upon further experimentation, the researchers discovered that it was also possible to switch between a solid and a molten structure.</div> <div><br /></div> <div>The discovery of how gold atoms can lose their structure in this way is not just spectacular, but also groundbreaking scientifically. Together with the theoretician Mikael Juhani Kuisma, from the University of Jyväskylä in Finland, Ludvig de Knoop and colleagues have opened up new avenues in materials science. The results are now published in the journal Physical Review Materials. </div> <div><br /></div> <div>Thanks to theoretical calculations, the researchers are able to suggest why gold can melt at room temperature. Possibly, the surface melting can be seen as a so-called low-dimensional phase transition. In that case, the discovery is connected to the research field of topology, where pioneers David Thouless, Duncan Haldane and Michael Kosterlitz received the Nobel Prize in Physics 2016. With Mikael Juhani Kuisma in the lead, the researchers are now looking into that possibility. <span style="background-color:initial">In any case, the ability to melt surface layers of gold in this manner enables various novel practical applications in the future.</span></div> <div><br /></div> <div>&quot;Because we can control and change the properties of the surface atom layers, it opens doors for different kinds of applications. For example, the technology could be used in different types of sensors, catalysts and transistors. There could also be opportunities for new concepts for contactless components,&quot; says Eva Olsson, Professor at the Department of Physics at Chalmers.</div> <div><br /></div> <div>But for now, for those who want to melt gold without an electron microscope, a trip to the goldsmith is still in order.</div></div> <div><br /></div> <div><span style="background-color:initial">Text: </span><span style="background-color:initial"> Joshua Worth,</span><a href="mailto:%20joshua.worth@chalmers.se"> joshua.worth@chalmers.se ​</a>and <span style="background-color:initial">M</span><span style="background-color:initial">ia </span><span style="background-color:initial">Hall</span><span style="background-color:initial">eröd</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"> Palmgren, </span><span style="background-color:initial"><a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se​</a></span><span style="background-color:initial"> </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="color:rgb(33, 33, 33);font-family:&quot;open sans&quot;, sans-serif;font-size:24px;background-color:initial">About the scientific article</span><br /></div> <div><div><span style="background-color:initial">The article </span><a href="https://journals.aps.org/prmaterials/abstract/10.1103/PhysRevMaterials.2.085006">“Electric-field-controlled reversible order-disorder switching of a metal tip surface​</a><span style="background-color:initial">” has been published in the journal Physical Review Materials.

He will tell the story about the fascinating journey which led to a groundbreaking underground discovery - and to the Nobel Prize in Physics 2015. ​</b></p><div><span style="background-color:initial"><img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/F/350x305/1_Takaaki_Kajita_350x305.jpg" alt="" style="margin:5px;width:320px;height:281px" />What he and Arthur B. McDonald had discovered was oscillations of elusive particles called neutrinos. In the Japanese underground observatory Kamiokande the research group led by Kajita could register the oscillations which showed that the particles, assumed to be massless, actually have mass. The discovery has had profound implications on for example stellar structure and cosmology. <br /></span><br /></div> <div>“Neutrinos are extremely fascinating particles, the second most common (after photons) in the Universe but so elusive that we have a hard time noticing their presence. They are potentially the key to understand some of the deepest questions that still remain unsolved,” says Professor Thomas Nilsson, experimental physicist and Head of the Department of Physics at Chalmers. <br /><br /></div> <div>Neutrinos were created at the birth of the Universe. Today they are created in nuclear processes – in the Cosmos, in our laboratories and in nuclear reactors.<br /><br /></div> <div>“When I joined Kamiokande, underground experiments were just a very small sub-field of particle physics experiments. At present, after more than 30 years, these underground experiments have become some of the most promising, powerful, versatile, and efficient ways to explore both particle physics and the Universe itself. This research underground continues to stimulate my interest. I look forward to what new discoveries the future will hold,” writes Professor Takaaki Kajita in The Nobel Prizes 2015, published on behalf of The Nobel Foundation. <br /><br /></div> <div>At Chalmers, many researchers are looking forward to Professor Kajita’s visit, especially physicists within astro, particle and subatomic physics. <br /><br /></div> <div> “I’m very glad for this event for several reasons. I studied particle physics as a student, but ended up as a reactor physicist, which is a completely different area. Nevertheless, both the existence of neutrinos, as well as two out of the three possible neutrino oscillations were proven by using neutrinos from nuclear reactors,” says Professor Imre Pázsit at the Department of Physics at Chalmers.<br /><br /></div> <div>Due to this fact, and to his extensive collaboration with Japanese physicists, Pázsit got into contact with the neutrino research quite some time ago. He met Professor Kajita in Stockholm in connection to the Nobel ceremony and at the Nobel Dialogue Dinner in Tokyo last year they met again.  <br /><br /></div> <div>“There I understood his interest to visit Sweden again, which of course helped to invite him to Chalmers. I look forward to his lecture and I hope that many will take the opportunity to listen to a fascinating talk,” says Professor Pázsit.</div> <div>Imre Pázsit has collaborated with Japanese researchers for more than 25 years.

Is this what my taxes are going to? There must be better ideas,” thought physics professor Jari Kinaret as he sat at Chalmers reading a number of proposals for EU research projects.So he wrote his own proposal, and sowed the seed that grew into Europe’s biggest research initiative ever – the Graphene Flagship.</b></p><div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/JariKinaretSV300x450.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />It was in late spring 2010 when the European Commission sent out the email that sparked Kinaret’s initiative. The Commission had sent an open invitation to submit project ideas for European research flagships. The Commission planned to invest major resources in the best projects, and competition was keen.</span></div> <div><span style="background-color:initial">“Some of the applicants had already been developing and lobbying for their ideas for a long time, but I wasn’t very impressed,” Kinaret says. “I thought graphene was a better idea, and I got the opportunity to present my proposal in Brussels. They said I would have five minutes for my presentation, but I only got three.”</span><br /></div> <div><h4 class="chalmersElement-H4">A whole world of new opportunities</h4></div> <div>At the time, graphene was a young, growing research field – both at Chalmers and elsewhere in Europe. But outside the research world, few people knew what graphene was – at least until the Nobel Prize in Physics was awarded that autumn: “A thin flake of ordinary carbon, just one atom thick, lies behind this year’s Nobel Prize in Physics. Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics.”</div> <div>That’s how the Royal Swedish Academy of Sciences described the ground-breaking discovery in its press release on 5 October 2010. </div> <div>Graphene is the very thinnest form of carbon, but it’s very strong. It also has unique heat and electricity conducting properties, which opens up a whole world of new opportunities. That’s what Kinaret focused on, and in autumn 2010 he submitted an initial application to the European Commission with a handful of partners around Europe. The application was accepted, and in the following year the consortium was expanded with dozens more partners. The big flagship application was prepared under Chalmers’ administration.</div> <div>The process took time, but in early 2013 he received the good news while travelling in Japan. The project had been granted EUR 1 billion for the coming 10 years, and the Graphene Flagship could be launched.</div> <div>“I was inundated with congratulations when I landed at Landvetter Airport,” Kinaret reminisces. “It was really a big deal that we’d succeeded. I remember we drank champagne with the University President.” Since then, Kinaret has headed the project, which is coordinated by the Department of Physics at Chalmers.</div> <div><h4 class="chalmersElement-H4">Graphene-based <span>products</span><span> </span><span>are starting to hit the shelves​</span></h4></div> <div>Today the Graphene Flagship has over 150 partners in more than 20 countries and involves in excess of 1,200 people. The overall goal is to transfer various types of graphene-based technology to society to create benefit, growth and job opportunities.</div> <div>“We can do extremely advanced things in the lab, but it’s a big challenge to go from small-scale craftsmanship to industrial manufacturing in giant series. It takes a long time to develop products, but the first graphene-based electronics products are starting to hit the shelves.”</div> <div>Examples include high-speed, highly sensitive detectors and bendable electronic gadgets. Other coming developments in the next few years are rapid-charging, flexible batteries with high storage capacity and more efficient fuel cells.</div> <div><span style="background-color:initial">There are already products on the market that have been “doped up” with graphene to improve their characteristics, such as stronger, lighter tennis rackets; motorcycle helmets and a Chalmers dinghy that literally flies across the water’s surface.</span><br /></div> <div>The future also holds possibilities that sound almost like science fiction. For example, an artificial retina. A blind person may be able to see using a small camera that communicates with a graphene membrane attached to the damaged retina. Since graphene can convert light to electrical signals, the brain can get the information it needs to see what the camera sees.</div> <div>“This type of technology already exists, but graphene can give better resolution,” Kinaret tells us in his calm, matter-of-fact way. “But there will be a very long development time before it can be put into use.”</div> <div><h4 class="chalmersElement-H4">A driving force to exceed expectations </h4></div> <div>There is no doubt that it will take a lot of tenacity, strength and patience to steer such a complex research vessel as the Graphene Flagship. But Kinaret seems to have the necessary perseverance. He is most proud when he succeeds at something he doesn’t feel he has a natural talent for.</div> <div>“Things that come to you easily are nothing to be proud of,” he says. “The greatest thing is always when you exceed expectations – above all your own. That’s the very hardest thing to do.”</div> <div><br /></div> <div><strong>And the tax money – is it going to the right things now? </strong></div> <div>“Yes, I’m happier than I would have been with the other alternatives. They weren’t all bad, but this is better,” he says candidly. </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Jari_Kinaret_inblick_0254_750x.jpg" alt="" /><span style="background-color:initial">Jari</span><span style="background-color:initial"> </span><span style="background-color:initial">Kinaret has visited Gunnebo House outside Gothenburg many times over the years. He often brought his family here when his children were small to look at the animals, walk through the grounds and enjoy coffee and cakes. Gunnebo House has another thing in common with Jari Kinaret and the Graphene Flagship – a clear link to the EU. The project “Gunnebo – back to the 18th century” was started with EU funding. While graphene is about building the future, Gunnebo is making the most of its historic environment.</span><br /></div> <div><br /></div> <h3 class="chalmersElement-H3">More about Jari Kinaret</h3> <div><strong>Born: </strong>27 February 1962 in Kokkola in the Ostrobothnia region of Finland. </div> <div><strong>Lives: </strong>A house in Mölndal outside Gothenburg. </div> <div><strong>Family: </strong>Wife and two daughters, aged 16 and 20.  </div> <div><strong>Job:</strong> Professor of physics at Chalmers, head of the Division of Condensed Matter Theory, director of the Graphene Flagship, which is the EU’s biggest research investment and is coordinated by the Department of Physics at Chalmers. </div> <div><strong>Career in brief</strong>: Earned a master’s degree in theoretical physics at Oulu University in 1986 and a degree in electrical engineering at the same university in 1987, before moving to the United States for further studies. He earned his doctorate in physics at the prestigious MIT in 1992 and spent some time working in Denmark. He came to Gothenburg in 1995 for a position at Gothenburg University, and since 1998 he has been on the Chalmers staff, where he has been a professor for ten years. Kinaret has also been the head of the Nanoscience and Nanotechnology Area of Advance at Chalmers. Since 2013 he has headed the Graphene Flagship. He is also in charge of the Division of Condensed Matter Theory at the Department of Physics.</div> <div><br /></div> <div><strong>Leisure interests:</strong> “My wife and I really enjoy jigsaw puzzles. The biggest one we have at home is probably 3,000 pieces. I also like mathematical puzzles, and I can clearly remember when I got my first Rubik’s cube at age 19. The first time, it took me two weeks to solve it, but then I practised a lot. My best time was 20–30 seconds. But it takes me longer now!”</div> <div><span style="background-color:initial"><strong>Favourite place for inspiration: </strong>“In the past I think it was the Delsjö area, where I did a lot of running. Now I don’t have any particular place where I get inspiration, but I like to visit Bertilssons Stuga (in the Delsjö Nature Reserve) or Gunnebo House for coffee.”</span><br /></div> <div><strong>Most proud of:</strong> “This is a question I often ask when conducting job interviews, so I’ve also considered what my own answer would be. Here are three things in chronological order where I exceeded my own expectations:</div> <div>1.<span style="white-space:pre"> </span>When I wrote my essay for my upper-secondary school diploma in Finland I got 98 of 99 points. That made me really proud because I don’t have a natural talent for writing.</div> <div>2.<span style="white-space:pre"> </span>After upper-secondary school, I did my military duty and got into the reserve officers’ academy. I’m good at reading, but this was something completely different, and far from my core skills. So I’m proud to have earned top marks there.</div> <div>3.<span style="white-space:pre"> </span>The Graphene Flagship – that was a big, important win. When we started out in 2010, we weren’t among the favourites, but we beat out the competition.”</div> <div><span style="background-color:initial"><strong>Motivation: </strong>“From the start, it was mostly curiosity. I’ve always liked mathematical reasoning. But the Graphene Flagship is different. It’s about seeing what we can accomplish with the project – how we can create real benefit in society.”</span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div><strong>First memory of physics:</strong> “Maybe this is more maths than physics, but I remember that we had a maths assignment in primary school where there was a mistake. The answer you got was a negative number, and I thought about what that meant. It turned out I had found a printing error in the book. I also remember reading about the Pythagorean theorem, which defines the relationship between the lengths of the sides of a right triangle. I was maybe seven or eight when I developed my own theorem that could be used for triangles that didn’t have a right angle. I remember that it sort of worked, and looking back, I’m really curious about how I managed that. I don’t have any paperwork left from it...”</div> <div><strong>The best thing about being a scientist: </strong>“Being able to decide what to work on. That’s a freedom that allows me to work on things that interest me. That freedom is the best thing, without a doubt.”</div> <div><strong>Challenges of the job: </strong>“Balance – ensuring a reasonable workload. It’s not good to have too much or too little work, but I tend to prefer having a bit too much when I know what I have to do… I’ve had problems with stress, and you need to set boundaries. In my role, it’s about trusting your employees and delegating more. You don’t always get everything your own way, but there’s no time to do everything yourself. You also need to take time to recuperate during periods with a lower workload.”</div> <div><strong>Dream for the future: </strong>“I dream of being able to find a way to allow future generations to live a life they’re happy with. It’s not obvious how we in Europe can create a competitive advantage over places like China and India. A large proportion of all manufacturing industries are outside Europe today, and we need to be involved in creating job opportunities for our children and grandchildren.”</div> <div><br /></div> <div><strong>Text: Mia Halleröd Palmgren</strong>, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se​</a></div> <div><strong>Foto 1: Henrik Sandsjö</strong></div> <div><strong>Foto2: Mia Halleröd Palmgren</strong></div> <div><br /></div> <div><div><a href="http://graphene-flagship.eu/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more about the Graphene Flagship.</a></div> <div><a href="http://www.chalmers.se/en/departments/mc2/news/Pages/GRAPHENE-CA-appointed-an-EU-Future-Emerging-Technology-Flagship-Pilot-.aspx%E2%80%8B"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the article about when Chalmers was entrusted with coordinating the research project (2013).​</a></div></div>Wed, 24 Oct 2018 00:00:00 +0200https://www.chalmers.se/en/centres/gpc/news/Pages/Pilote-activites-at-FysikLek.aspxhttps://www.chalmers.se/en/centres/gpc/news/Pages/Pilote-activites-at-FysikLek.aspxPilote activites at &quot;FysikLek<p><b></b></p><div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/fysiklek_anders_collage_600xNY.jpg" alt="" style="margin:5px" /><br /><br />The corridor and rooms that will house ”FysikLek”, the physics toys and pedagogical centre, is slowly taking shape in Origo building, floor 3 (Kemivägen 1, Gothenburg). <br /></div> <div>A lot of people have been involved, from the design and building led by Peter Apell at Chalmers to a pedagogical team, led by Jonas Enger at the University of Gothenburg, to mention just a few.

In recent years,</span><span style="background-color:initial"> she has also noted a growing interest from food producers. There seems to be a commercial interest to invest in lab-grown meat.</span><br /></div> <div>“Just recently, I had an exciting meeting with a major food producer that wanted to learn more about how to produce cultured meat. We’ll see where that leads.”</div> <h4 class="chalmersElement-H4">A passionate and rewarded pedagogue</h4> <div>But for Gold, her own research is far from all-consuming. She is also passionate about education issues, teaching methods and helping others to grow. She loves teaching and guiding undergraduate and doctoral students. Over the years, she has established many new courses and a new graduate school in bioscience, and she’s headed several projects to develop postgraduate studies at Chalmers. One of her contributions is a new tool that facilitates the interaction between supervisors and their doctoral students. She has developed activities for improving supervisors’ skills, as well as courses in Generic and Transferable Skills for both personal and professional development.</div> <div>A few years ago, her efforts were rewarded with Chalmers’s 2015 pedagogical award.</div> <h4 class="chalmersElement-H4">Developed an online course in Singapore</h4> <div>Recently, Gold was also one of a handful of selected Swedish scientists who were given the opportunity to share their teaching skills in other parts of the world. In autumn 2017, she worked in Singapore, developing an online course for master’s students. The result was a brand-new course in biomaterials at Nanyang Technological University.</div> <div>“It was a hectic term, but an incredibly exciting project. I recorded my lectures in an advanced TV studio, with a whole team of people working with me. There were people in charge of graphics, design, content, interactivity… I was also coached by a very skilled pedagogy expert. It was incredible.”</div> <div>The course was held for the first time in Spring 2018, and now Gold is going to compare the study results of the online course in Singapore with those for the same course held on-site at Chalmers.</div> <div>“It will be exciting to evaluate the learning outcomes and how the students felt about the instruction, depending on whether or not the teacher was in the room.”</div> <h4 class="chalmersElement-H4">Challenges herself on the horseback</h4> <div>Her time in Singapore was also exhilarating after many years in the same workplace. Although she seems to have been very successful outwardly, over the years she has also encountered many obstacles and occasional uphill battles.</div> <div>“My topic is biomaterials, not physics, and sometimes it felt as if my research and teaching fell between two departments. Because I’ve had difficulty getting funding for lab-grown meat, I’ve also felt that I was a financial burden on the department.”</div> <div>When she aired these thoughts with her old manager, Bengt Kasemo, he had one concrete suggestion: “I think you should take up riding,” he said. Gold was 45 years old and had never been involved with horses before, but she accepted the challenge.</div> <div>“Starting riding was the best thing I’ve ever done for my own self-confidence. I challenged myself and my fears, and today I can manage to jump fences without being nervous.”</div> <div>She rides weekly at the Billdal Riding Club, and equestrian skills aren’t all that she’s learned. She’s also learned more about communication.</div> <div>“Horses sense your emotional state right away, so you have to be sure of yourself. It’s a fantastic experience, feeling that you become one with the horse when you’re galloping full speed around a course. It’s all about trusting each other.”</div> <div>Her experiences from the stable have also allowed her to tackle projects from a new perspective at work.</div> <div>“Horses have given me greater self-esteem, and that has helped me to overcome obstacles in my professional life as well,” she says, offering a treat to one of her favourite coaches in the stable – the placid gelding Ronaldo.</div> <div><br /></div> <h3 class="chalmersElement-H3">More about ​Julie Gold</h3> <div><strong>Born: </strong>3 September 1963 in New Jersey, USA.</div> <div><strong>Lives:</strong> A flat in Guldheden, Gothenburg.</div> <div><strong>Family: </strong>One child, in-laws, a sister, and close friends.</div> <div><strong>Job: </strong>Professor at the Department of Physics at Chalmers and chairperson of the Chalmers Employment Committee.<br /></div> <div><strong>Career in brief:</strong> Began her academic career in New York, where she studied biomedical engineering at the Rensselaer Polytechnic Institute. She specialised in materials science and became increasingly interested in surface physics – particularly through her contact with Chalmers professor Bengt Kasemo. Having almost completed her doctorate in biomedical <span>engineering<span style="display:inline-block"></span></span>, she chose to switch tracks. After a few short assignments in Switzerland and the United States, she accepted Kasemo’s invitation to continue her career at Chalmers. In 1996, she earned her doctorate in materials science. Over the years she has held several elected positions and headed a variety of projects – including the MISTRA Environmental Nanosafety research project. Gold has received Chalmers’s pedagogical award and has been one of the institution’s most quoted researchers in the media. Recently she worked in Singapore for six months, developing an online course for master’s students in biomaterials at Nanyang Technological University. Her sabbatical year was funded by the Swedish Foundation for International Cooperation in Research and Higher Education, STINT.</div> <div><br /></div> <div><span style="background-color:initial"><strong><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Julie_Gold_hastprat_300x.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" />Leisure interests: </strong>“I ride twice a week at the Billdal Riding Club. I love riding out in the woods. I also work out at the gym and love gardening and being out in nature. When I lived in Singapore, I swam a lot, and I like swimming in the sea here at home, too.”</span><br /></div> <div><strong>Favourite place for inspiration: </strong>“Being by the water or on horseback, and feeling the wind in my face is the best thing. I like places where I can swim or ride. As a little girl I wanted to be a figure skater, and I did a lot of ice skating. I think that was about freedom and the wind in my face, too. It makes me feel graceful and light.”</div> <div><strong>Most proud of:</strong> “My students and all the great relationships I have with my current and previous students. I’m so happy and proud that I can help and inspire others.”</div> <div><strong>Motivation: </strong>“Helping others and seeing students and colleagues grow. That’s more important than my own successes. I’m more interested in the people doing the research and in my professional relationships than in getting articles published in Nature. I think we scientists should work together more, compete less with each other and start seeing ourselves as colleagues rather than competitors. Broader collaborations between different groups benefit all of society.”</div> <div><br /></div> <div><strong>First memory of physics:</strong> “My father was a mathematician and he showed me how the amount of water in a glass affects the sound the glass makes when you tap on it with a spoon. We created a real musical instrument together.”</div> <div><strong>Best thing about being a scientist:</strong> “There’s a sort of freedom – being able to steer and choose your work yourself. There are so many questions that don’t have answers, and you’re trying to work out how something works. You’re treading on unfamiliar territory and you have the freedom to try different things. As a faculty member, I have so many fun assignments, particularly when it comes to teaching and all the people I meet in my job.

But much of his work involves paving the way for hydrogen vehicles’ breakthrough. Physics professor Christoph Langhammer at Chalmers is developing hydrogen gas sensors that will hopefully help to get us there. In his work, he gets to know the smallest individuals that can make this possible.​</b></p><div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/ChristophLanghammerSV300x450.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“The smaller they are, the more interesting they become,” Langhammer says, as he offers us a cup of coffee on his family’s sailing boat. “I want to get to know each and every one of them and see how they interact with the world. I’m very interested in small individuals.”</span></div> <div>What he’s talking about are nanoparticles. His research team is investigating how nanomaterials work and how they can be used for applications, such as sensors. Langhammer compares nanoparticles to a crowd of people, using the example of an audience at a concert. From a distance, everyone looks alike, but the closer you get, the more unique traits you can observe in each individual. To get nanoparticles to work in a specific way, the particles’ properties must be matched to the task. When that happens, they can achieve great things, such as contributing to safe, and environmentally friendly vehicles that emit nothing but water. </div> <div><h4 class="chalmersElement-H4">Sensors with <span>high safety requirements​</span></h4></div> <div>But hydrogen gas involves a lot of challenges, because the hydrogen molecule is particularly troublesome: It’s small, light and likes to leak. It’s also invisible, odourless and extremely flammable. Just a four per cent concentration of hydrogen in the air creates an explosive blend that can be ignited by the tiniest spark.</div> <div>“To ensure that hydrogen vehicles are safe enough, we’ll need extremely efficient hydrogen gas detectors,” he explains. “They have to be able to detect minuscule amounts of hydrogen in the air in order to stop any leaks before an ignitable hydrogen concentration is reached. So far, there is no competitive technology that meets the high safety requirements of the vehicle industry, but we are well on our way to developing such technology. It would be fantastic if we were the first to meet those demands.”</div> <div>What many would call a researcher’s dreams, he sees as goals or visions. To achieve them, he has chosen to work with both fundamental research and applications. This ensures that he asks the right questions and develops the methods necessary to advance his research. This approach is one of the reasons he has managed to build up a broad funding base.<span style="background-color:initial">​</span></div> <h4 class="chalmersElement-H4">Looked for a warm place  <span style="font-size:14px">–</span> ended up in Sweden...</h4> <div>You might think he would have been just as strategic in choosing his profession, but that wasn’t the case. Christoph Langhammer had a broad range of interests. He likes architecture, archaeology and chemistry, but maths was not his strong suit. He focused on languages in upper-secondary school, played competitive handball and nearly became a fighter pilot. Then he studied materials science, because it was interdisciplinary and broad. He enjoyed it so much that when it was time to do his degree project, he decided to continue his studies abroad. Somewhere warm by the sea – preferably in the United States. But it didn’t work out that way – instead he went north to Sweden and Chalmers, attracted by great colleagues and first-class research.</div> <div>His linguistic interest helped him out in his new country, and today he speaks eight languages. Although he moved to Sweden as an adult, he speaks the language like a native. That might not have been the case if “his” desk hadn’t been occupied when he got back to Chalmers to pursue his doctorate in 2004.</div> <div><span style="background-color:initial">The place where he had worked on his degree project was now occupied by a female doctoral student from the province of Värmland. Her name was Elin Larsson. It turned out they had a lot in common. Today, her name is also Langhammer and they have two children. They also work together in a company that they started in collaboration with their supervisors after defending their doctoral theses.</span><br /></div> <h4 class="chalmersElement-H4">Similarities between sailing and research</h4> <div><span style="background-color:initial">They also share a passion for sailing, and Christoph breathed a sigh of relief when they bought a boat together.</span><br /></div> <div>“I co-owned my first boat with a female doctoral student who couldn’t swim. Her boyfriend was the one who wanted to sail; she was terrified. Those were some really difficult voyages...”</div> <div>Even though sailing and research are very different things, there are several similarities.</div> <div>“There are technical challenges, the need to focus on what you’re doing and the interplay of many factors. I don’t race, but I am a competitive person and I like that you can always trim your sails a bit better…”</div> <div>In research, there are also moments that are completely ultimate. When the present is more exciting than the vision.</div> <h4 class="chalmersElement-H4">A feeling that can't be beaten...</h4> <div><span style="background-color:initial">“It’s fantastic when my research team finally manages to piece together the puzzle of an exciting question and understand how something works and what we are measuring. Because we work closer and closer in the team, as well as with our colleagues at Chalmers and internationally, our research is moving forward, both theoretically and experimentally.”</span><br /></div> <div><span style="background-color:initial">In his role as a PhD supervisor, Langhammer also has the opportunity to let others blossom.</span><br /></div> <div>“A really high-quality doctoral thesis defense is a sheer pleasure. It’s so wonderful to look back on the journey that person has made from a beginner in the lab to an expert in their field, and to see how passionate they are about their topic. That feeling that the person is now ready to take the next step in their career on their own, with no need of a supervisor anymore, is extremely satisfying, combined with the knowledge that we have brought the research forward. That feeling can’t be beaten.”</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Christoph_Langhammer_750x420.jpg" alt="" style="margin:5px" />​<span style="background-color:initial">Christoph Langhammer is happiest on board the family’s sailing boat, a Maxi 1100.

He earned his master’s degree in 2004 and did his degree project at Chalmers. He then continued his path at Chalmers, earning his PhD in 2009. After that, he co-founded the company Insplorion. In 2013 he was promoted to associate professor. Currently, Langhammer heads a group of 13 people whose research is funded by the Swedish Research Council, the Swedish Foundation for Strategic Research, the European Research Council ERC, and the Knut &amp; Alice Wallenberg Foundation. He is also an “SSF Future Research Leader” and a “Wallenberg Academy Fellow”.</div> <div><br /></div> <div><strong>Leisure interests: </strong>“Previously, it was mostly handball. I played in the top division of the Swiss Handball League and in IK Celtic after moving to Gothenburg. I started sailing when I was working on my doctorate – it’s an interest I share with my wife, Elin. I like being out in nature, and sailing with my family is not only a great way to spend time together, it’s also a great way to relax. The kids and I also go swimming every week, and I enjoy cooking.”</div> <div><strong>Favourite place for inspiration:</strong> “Inspiration can strike just about anywhere. It might be something I see, hear or read, or it strikes when I’m busy doing something completely different, like playing with the kids, cooking or sailing.”</div> <div><strong>Most proud of: </strong>“Being an involved father while maintaining a research career. When the kids hurt themselves, they’re just as likely to come running to me as to their mother. That’s a great feeling. To balance work and family, I choose to say no to a lot; I rarely travel for work and I make sure to be extremely well organised.”</div> <div><strong>Motivation</strong>: “I’m motivated by the desire to constantly improve and to better understand how something works. I want the things I do to turn out very well, or else I don’t want to do them at all. I also want to get answers to my questions and I like challenging myself. How far can I pursue something, how can I prove that it’s possible? I’m definitely a competitive person, and I like to compete with myself.”</div> <div><br /></div> <div><strong>First memory of physics:</strong> “The first time I remember really thinking about physics and its implications was when I made a solar cell. It only generated a little bit of current, but it worked and it was cool.”</div> <div><strong>Best thing about being a scientist:</strong> “That moment when all the questions are answered. That feeling when, at least for the moment, you have no more questions to ask and everything seems to make perfect sense. The idea that no one else has achieved this level of understanding in this particular question is really cool. It makes me feel that I’m contributing to the development of our society, which is the goal of research.”</div> <div><strong>Challenges of the job:</strong> “Constantly having to make sure that my research has enough funding is one of them. You have to maintain what you’ve built up and make sure not to lose the knowledge and skills in the team. It’s also a great challenge having to be good at so many things in my job. Apart from the research itself, you have to be good at writing applications and publications, guiding employees, teaching, supervising and taking an interest in the development of the department and the research community as a whole. At the same time, I grow and evolve as a person when I take on these tasks.”</div> <div><strong>Dream for the future:</strong> “I don’t have any need of dreaming at the moment. To be honest, I have difficulty believing that it’s possible to have much of a better life than I have today – both professionally and personally. But I do have objectives – visions that are based on reality. One example is developing a hydrogen gas detector that meets all the requirements of the vehicle industry to ensure that the vehicles are safe – that would be fantastic. The only emission from a car that runs on hydrogen gas is water.”</div> <div><br /></div> <div><strong>Text: Mia Halleröd Palmgren</strong>, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se​</a></div> <div><strong>Image 1: Henrik Sandsjö</strong></div> <div><strong>Image 2: Mia Halleröd Palmgren</strong></div>Wed, 17 Oct 2018 00:00:00 +0200https://www.chalmers.se/en/news/Pages/The-Commissioner-curious-about-graphene.aspxhttps://www.chalmers.se/en/news/Pages/The-Commissioner-curious-about-graphene.aspxThe Commissioner curious about graphene<p><b>​EU Commissioner Cecilia Malmström visited Chalmers to find out more about the research on graphene, the flagship project and industrial opportunities for Europe.</b></p>​During a visit to Gothenburg, Cecilia Malmström attended the MC2 Department at Chalmers, and heard more about the proceedings in one of the world's largest research projects, the Graphene Flagship.<br /><br />She was received by President Stefan Bengtsson, and Professor Jari Kinaret told her about the setup. He is responsible for coordinating around 1000 graphene researchers from 150 different partners in 20 countries.<br /><br />&quot;Brexit is one of the most important issues for us. Between 16 and 18 percent of the budget in the flagship project is allocated to research groups in Britain,&quot; said Jari Kinaret.<br /><br />Five years after the start of the project, more and more consumer products are released on the market with alleged graphene content – that is, carbon in single atomic layers with a characteristic hexagon shape that gives the material superior properties. Often sports products are said to be stronger or cooler through the use of graphene. But it's difficult to know how much graphene they actually contain, and what quality of graphene.<br /><br />&quot;I understand, standardisation and validation of what graphene really is, it's central now,&quot; said EU Commerce Commissioner Cecilia Malmström.<br /><br />The discussion was about which countries are ahead when it comes to different types of applications. Reinforced airplane wings, reinforced concrete, high speed electronics and graphene-coated boat hulls, which could make poisonous antifouling superfluous, were some examples around which the conversation circulated.

The results have been published in Nature Communications. The methods can be used to improve many different types of catalysts.​</b></p><div>Catalysts are materials which cause or accelerate chemical reactions. For most of us, our first thought is probably of catalytic converters in cars, but catalysts are used in a number of areas of society – it has been estimated that catalysts are used in the manufacture of more than 90 percent of all chemicals and fuels. No matter how they are used, catalysts operate through complex atomic processes. In the new study from Chalmers, physics researchers combined two approaches to add a new piece to the catalyst puzzle. They used advanced, high-resolution electron microscopy and new types of computer simulations.</div> <div><br /></div> <div>&quot;It is fantastic that we have managed to stretch the limits and achieve such precision with electron microscopy. We can see exactly where and how the atoms are arranged in the structure. By having picometre precision – that is, a level of precision down to one hundredths of an atom’s diameter – we can eventually improve the material properties and thus the catalytic performance,&quot; says Torben Nilsson Pingel, researcher at the Department of Physics at Chalmers and one of the authors of the scientific article.</div> <div><br /></div> <div>Through this work, he and his colleagues have managed to show that picometre-level changes in atomic spacing in metallic nanoparticles affect catalytic activity. The researchers looked at nanoparticles of platinum using sophisticated electron microscopes in the Chalmers Material Analysis Laboratory. With method development by ​Andrew Yankovich, the researchers have been able to improve the accuracy and can now even reach sub-picometre precision. Their results now have broad implications.</div> <div><br /></div> <div>&quot;Our methods are not limited to specific materials but instead based on general principles that can be applied to different catalytic systems. As we can design the materials better, we can get both more energy-efficient catalysts and a cleaner environment,&quot; says Eva Olsson, Professor at the Department of Physics at Chalmers.</div> <div><br /></div> <div>The work was carried out within the framework of the Competence Centre for Catalysis at Chalmers. In order to study how small changes in atomic spacing really affect the catalytic process, Mikkel Jørgensen and Henrik Grönbeck, PhD student and Professor at the Department of Physics respectively, performed advanced computer simulations at the national computing centre, located at Chalmers. Using the information from the microscope, they were able to simulate exactly how the catalytic process is affected by small changes in atomic distances.</div> <div><br /></div> <div>“We developed a new method for making simulations for catalytic processes on nanoparticles. Since we have been able to use real values in our calculation model, we can see how the reaction can be optimised. Catalysis is an important technology area, so every improvement is a worthwhile advance – both economically and environmentally,” says Henrik Grönbeck.</div> <div><br /></div> <div>Text: <span style="background-color:initial">M</span><span style="background-color:initial">ia </span><span style="background-color:initial">Hall</span><span style="background-color:initial">eröd</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"> Palmgren, </span><span style="background-color:initial"><a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se​</a></span><span style="background-color:initial"> </span></div> <div><span style="background-color:initial">and Joshua Worth,</span><a href="mailto:%20joshua.worth@chalmers.se"> joshua.worth@chalmers.se </a></div> <div><br /></div> <div>Image: Johan Bodell, <a href="mailto:%20johan.bodell@chalmers.se%E2%80%8B">johan.bodell@chalmers.se​</a></div> <div><img src="/SiteCollectionImages/Institutioner/F/750x340/CMAL_181008_Eva_Henrik_mfl_PM_05_750x340.jpg" alt="" style="margin:5px" /><br />Fine-tuning at the atomic level can result in better catalysts and a cleaner environment.

The laboratory formally belongs to the Department of Physics, but is open to all researchers from universities, institutes and industry. The experiments in this study have been carried out using advanced and high-resolution electron microscopes - in this case, transmission electron microscopes (TEM). Major investments have recently been made, to further push the laboratory to the forefront of material research. In total, the investments are about 66 million Swedish kronor, of which the Knut and Alice Wallenberg Foundation has contributed half.</div> <a href="http://www.chalmers.se/en/departments/physics/news/Pages/How-to-design-smart-materials-for-the-future.aspx"><div><br /></div> <div><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read a previous news article: <span style="background-color:initial">How to design smart materials for a sustainable future </span>​</div> <div><br /></div></a><a href="http://www.chalmers.se/sv/forskningsinfrastruktur/CMAL/Sidor/default.aspx"><div><span><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" /></span>Read more about Chalmers Material Analysis Laboratory.​</div></a><div><br />​<a href="http://www.chalmers.se/en/centres/KCK/Pages/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about the Competence Centre for Catalysis at Chalmers. </a></div> <div><br /></div> <div>The computer simulations were performed at the Chalmers Centre for Computational Science and Engineering (C3SE), which is a centre for scientific and technical calculations at Chalmers.

Using this technique makes it possible to study individual atoms. There are different types of electron microscopes, such as transmission electron microscopes (TEM), scanning transmission electron microscopes (STEM), scanning electron microscopes (SEM) and combined Focused Ion Beam and SEM (FIB-SEM). </div> <div><img src="/SiteCollectionImages/Institutioner/F/750x340/CMAL_181008_Eva_Henrik_titan06_750x340.jpg" alt="" style="margin:5px" /><br />The experiments in this study have been carried out using advanced and high-resolution electron microscopes - in this case, transmission electron microscopes (TEM) at <span style="background-color:initial">Chalmers Material Analysis Laboratory</span><span style="background-color:initial">  in Gothenburg, Sweden.
