In a new research project, Chalmers researchers will develop new genetically modified cells, so-called cell factories, which can produce the desired proteins.</b></p>​The market for pharmaceutical drugs that based on human proteins (protein drugs), is continuously increasing.<br /><br />&quot;Protein drugs give a more targeted effect and less side effects than traditional drugs based on small molecules,&quot; explains Jens Nielsen, Professor of Systems Biology at Chalmers.<br /><br />The hope is that you will be able to treat a very wide range of diseases, for example different types of cancer, diabetes or multiple sclerosis. The proteins are produced by the so-called cell factories - cells that are genetically modified to produce and secrete the desired protein. The problem is that it is difficult at present to produce some of these proteins.<br /><br />&quot;For some proteins it is straightforward to produce them, but with others it does not work at all. And we do not really know why, &quot;says Jens Nielsen.<br /><br />Now, the research groups of Jens Nielsen and Associate Professor Dina Petranovic, (Chalmers), with researchers at KTH, received a grant of SEK 34 million from the Foundation for Strategic Research to investigate protein production by a human cell line and by yeast cell factories, which the group has very much experience with.<br /><br />&quot;We want to understand why it doesn’t’ work sometimes, so we can then modify the cell factories to produce more different types of protein,&quot; says Jens Nielsen.<br /><br />Cell factories based on human cell lines are not yet commercially available. Today, most of pharmaceutical proteins are produced primarily by Chinese Ovary Hamster (CHO) cell lines. Pharmaceutical proteins produced in non-human cell lines can be identical to human proteins, or have very small differences which in some patients, the difference may give rise to a response from the immune system.<br /><br />&quot;With cell factories based on human cells, we aim to get completely identical proteins which would not induce such reactions,&quot; says Jens Nielsen.<br /><br />The long-term vision is that with cell factories it will be possible to produce all the desired proteins so that the needed protein pharmaceuticals come more quickly onto the market.<br /><br />Read more:<br /><a href="/sv/institutioner/bio/nyheter/Sidor/Proteinforskning-Jens.aspx">Pharmaceutical products based on human proteins </a>(in Swedish)<br /><br />Text: Ingela Roos<br />Photo: Johan BodellThu, 22 Jun 2017 17:00:00 +0200http://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Collaboration-crucial-for-transitioning-to-a-sustainable-society.aspxhttp://www.chalmers.se/en/areas-of-advance/energy/news/Pages/Collaboration-crucial-for-transitioning-to-a-sustainable-society.aspxCollaboration crucial for transitioning to a sustainable society<p><b>​How do we successfully transition to a sustainable society, as fast as the climate requires?

However, imitating the solar energy process is a difficult task to achieve. Two young plasma physicists at Chalmers University of Technology have now taken us one step closer to a functional fusion reactor. Their model could lead to better methods for decelerating the runaway electrons, which could destroy a future reactor without warning.</b></p><div>​It takes high pressure and temperatures of about 150 million degrees to get atoms to combine. As if that was not enough, runaway electrons are wreaking havoc in the fusion reactors that are currently being developed. In the promising reactor type tokamak, unwanted electric fields could jeopardise the entire process. Electrons with extremely high energy can suddenly accelerate to speeds so high that they destroy the reactor wall. <br /> <br /></div> <div><span><img src="/SiteCollectionImages/Institutioner/F/340x296px/LinneaOla340x296IMG_0991.jpg" class="chalmersPosition-FloatRight" width="272" height="237" alt="" style="margin:5px" /></span>It is these runaway electrons that doctoral students Linnea Hesslow and Ola Embréus have successfully identified and decelerated. Together with their advisor, Professor Tünde Fülöp at the Chalmers Department of Physics, they have been able to show that it is possible to effectively decelerate runaway electrons by injecting so-called heavy ions in the form of gas or pellets. For example, neon or argon can be used as “brakes”. <br /><br />When the electrons collide with the high charge in the nuclei of the ions, they encounter resistance and lose speed. The many collisions make the speed controllable and enable the fusion process to continue.  Using mathematical descriptions and plasma simulations, it is possible to predict the electrons' energy – and how it changes under different conditions. </div> <div> </div> <div>“When we can effectively decelerate runaway electrons, we are one step closer to a functional fusion reactor. Considering there are so few options for solving the world's growing energy needs in a sustainable way, fusion energy is incredibly exciting since it takes its fuel from ordinary seawater,” says Linnea Hesslow. </div> <div> </div> <div>She and her colleagues recently had their article published in the reputed journal Physical Review Letters. The results have also attracted a great deal of attention in the field of research. In a short period of time, 24-year-old Linnea Hesslow and 25-year-old Ola Embréus have given lectures at a number of international conferences, including the prestigious and long-standing <a href="http://www.sherwoodtheory.org/index.php">Sherwood Fusion Theory Conference in Annapolis</a>, Maryland, USA, where they were the only presenters from Europe. </div> <div> </div> <div>“The interest in this work is enormous. The knowledge is needed for future, large-scale experiments and provides hope when it comes to solving difficult problems. We expect the work to make a big impact going forward,” says Professor Tünde Fülöp. </div> <div> </div> <div>Despite the great progress made in fusion energy research over the past fifty years, there is still no commercial fusion power plant in existence. Right now, all eyes are on the international research collaboration related to <a href="http://www.iter.org/">the ITER reactor in southern France.</a><br /><br /></div> <div>“Many believe it will work, but it's easier to travel to Mars than it is to achieve fusion. You could say that we are trying to harvest stars here on earth, and that can take time. It takes incredibly high temperatures, hotter than the center of the sun, for us to successfully achieve fusion here on earth. That's why I hope research is given the resources needed to solve the energy issue in time,” says Linnea Hesslow.<br /><br /></div> <div>Text and image: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se</a></div> <div> <img src="/SiteCollectionImages/Institutioner/F/750x340/fusionsreaktor_image_EUROfusion750x340.jpg" alt="" style="margin:5px" /><br /><span>Although the vacuum chamber in the British fusion reactor JET has a wall made of solid metal, it can melt if it gets hit by a beam of runaway electrons.

The energy is created the same way as in the sun, and the process can also be called hydrogen power. Fusion power is a much safer alternative than nuclear power, which is based on the splitting (fission) of heavy atoms. If something goes wrong in a fusion reactor, the entire process stops and it grows cold. Unlike with a nuclear accident, there is no risk of the surrounding environment being affected. The fuel in a fusion reactor weighs no more than a stamp, and the raw materials come from ordinary seawater. </div> <div>As yet, fusion reactors have not been able to produce more energy than they are supplied. There is also a problem with so-called runaway electrons. The most common method of preventing this damage is to inject heavy ions, such as argon or neon, which act like brakes due to their large charge. A new model developed by researchers at Chalmers describes how much the electrons are decelerated, paving the way to making these runaway electrons harmless.  <br /><br /></div> <div>Read the scientific article <a href="https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.118.255001">“Effect of partially-screened nuclei on fast-electron dynamics&quot;</a>.<br /></div> <div>  <br /></div> <div>The article was written by Linnea Hesslow, Ola Embréus, Adam Stahl, Timothy DuBois, Sarah Newton and Tünde Fülöp of the Department of Physics at Chalmers University of Technology, and Gergely Papp of the Max Planck Institute for Plasma Physics in Garching, Germany. <br /></div> <h3 class="chalmersElement-H3">More information: <br /></h3> <div><span><a href="/en/Staff/Pages/hesslow.aspx"><strong><span><strong>Linnea Hesslow</strong></span></strong><span></span></a>,</span> PhD Student, Department of Physics, Chalmers University of Technology, +46 70 519 41 67, hesslow@chalmers.se</div> <div><strong><a href="/en/staff/Pages/embreus.aspx">Ola Embréus</a></strong>, PhD Student, Department of Physics, Chalmers University of Technology, +46 73 052 80 70, embreus@chalmers.se</div> <div><strong><span><a href="/en/Staff/Pages/Tünde-Fülöp.aspx">Tünde Fülöp</a></span></strong>, Professor, Department of Physics, Chalmers University of Technology, +46 72 986 74 40, tunde.fulop@chalmers.se<br /><br /><a href="http://www.mynewsdesk.com/uk/chalmers/pressreleases/deceleration-of-runaway-electrons-paves-the-way-for-fusion-power-2023834"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release and download high resolution images. </a><br /></div>Tue, 20 Jun 2017 00:00:00 +0200http://www.chalmers.se/en/departments/mc2/news/Pages/Fifth-networking-event-for-AoA-Nano.aspxhttp://www.chalmers.se/en/departments/mc2/news/Pages/Fifth-networking-event-for-AoA-Nano.aspxFifth networking event for AoA Nano<p><b>​16 June is the last chance to enroll in the annual community building event with the Nanoscience and Nanotechnology Area of Advance (AoA).

The AUV is an important resource in the national infrastructure MUST (Mobile Underwater System Tools) at the University of Gothenburg and the first of its kind in Sweden.</b></p>​With the new underwater vehicle it will be possible to make detailed studies of the sea bottom on very large depths and to follow the climate thousands of years back in time.<br /><br />- The most interesting thing with the AUV for us is that it gives us the possibility to get in under the sea ice in the Arctic Ocean and around Antarctica to measure the thickness of the ice. Says Leif Eriksson from Space, Earth and Environment, Chalmers’ representative in the steering committee for MUST.<br /><br />To make this kind of measurements has so far been very difficult. The results from the new underwater vehicle will be compared with the measurement results that Leif and his colleagues in the Division of Microwave and Optical Remote Sensing have from their satellite measurements of the sea ice. With this comparison they hope to be able to enhance the methods for estimation of the thickness of the sea ice and decrease the uncertainty about the total sea ice volume, how it is distributed geographically and how it varies over time.<br /><br />- It will be very exciting to see what information these measurements give.

Of course we should jointly take advantage of all this and the many new impulses that exchanges between our University provides, says Chalmers President Stefan Bengtsson.”<br /><br />More PhD students are to do their programmes across the five partner universities in the Nordic Five Tech alliance. That was the wish expressed by the presidents of the leading technical partner universities in Denmark, Finland, Norway, and Sweden when they met on 1 June at DTU.<br /><br />Here, they agreed on recommending a common guideline which all heads of PhD schools and supervisors are encouraged to follow. PhD students can, among other things, spend 6-12 months at another of the alliance’s universities and get a supervisor at both universities. The alliance has also established a common course database that everyone can use.<br /><br />“The PhD collaboration supports the alliance’s vision of building up an ‘extended campus’ where employees and students can benefit from the individual universities’ specialized competences, advanced infrastructures, and unique study programmes,” says Anders Overgaard Bjarklev, DTU President.<br /><br />Nordic Five Tech is already collaborating on offering five joint MSC programmes, on quality assuring the Nordic study programmes, and on research within selected Nordic fields of excellence, including the Arctic. In the coming year, the collaboration will be expanded to cover new fields. General supplementary education courses will be developed, among other things, and the collaboration on innovation and entrepreneurship will be given high priority.<br /><br />According to Times Higher Education, the five partner universities are among the world’s 55 leading ‘Technology Challengers’.

The Chalmers and Climate-KIC supported start-up ChillServices seek to change that by saving around 3 to 5 % with easy implemented measures, and the researchers are convinced that 30-40% efficiency improvement is within reach.</b></p>​<span>​Refrigeration is one of the main drivers in supermarkets energy consumption, almost 50 % of the total. Almost 10 years ago, 2 guys started to ask questions about this consumption: How do you deal with internal heat within a supermarket? How much is this amount of heat? Where is the energy wasted and how could this be changed? This genuine interest was the start of a unique relationship between York Ostermeyer, his team and the REWE supermarket chain in Northern Germany.<span style="display:inline-block"></span></span><h5 class="chalmersElement-H5">A handshake agreement</h5> <p>A few years later (2014) the team originally formed at ETH Zürich, had moved to Chalmers and been complemented with <a href="/en/staff/Pages/tommiem.aspx">Tommie Månsson</a>, a PhD student interested in CFD modelling, and <a href="/en/staff/Pages/cmarx.aspx">Christian Marx</a>, a postdoc with a focus on remote sensoring. Investigations under the Climate-KIC flagship BTA, led to the development of a service and a product – the so called RDC FieldAgent and the SensorHold. Because of the existing strong relationship to REWE, it took a handshake to start a first pilot. Very rare, because supermarkets normally don’t work with Universities and co-operations are legally boarded.<br /><br /></p> <h5 class="chalmersElement-H5">Astonishing outcome</h5> <p>The first evaluation had an outcome of decreased electricity consumption for each doored<span> </span>refrigerated display cabinet<span> </span>(RDC) by 3 %, which is approx. 6,000 kWh, roughly 4-5 tons CO2per retail store per year. After further improvement of the product and complementing it with a smartphone APP, REWE ordered the SensorHold for 1.500 RDCs with a total project volume of 300 kEUR. All managed by the start-up ChillServices, which was founded by Climate-KIC BTA and Chalmers University at the end of 2016.</p> <p>“We took some very hands-on measurements initially: e.g. we bended a piece of metal for our hotspot analysis, which we professionalised after the pre-tests. Very easy! With only a few clicks the craftsmen install the system and via the smartphone app we monitor the process and ensure the quality. As part of the process we generate a lot of data that can be used to tailor further services to our client. The energy saving that we enable is actually quite an achievement, as REWE is already the most advanced supermarket in terms of energy efficiency.“ – <a href="/en/Staff/Pages/york-ostermeyer.aspx">York Ostermeyer</a>, Associate Professor Chalmers University and co-founder of the ChillServices company</p> <p>“We are always scouting the market for ways to further improve the energy efficiency of our markets. The work with a Spin-off of an academic institution however is the first time for us. So far, it’s been an inspiring cooperation that generated some outstanding results with new learnings for everybody involved. With all the attention this is getting, I am optimistic that this can turn into a role model.”<span> </span>– Jan Lahmann, Head of Energy Management REWE North.<br /><br /></p> <h5 class="chalmersElement-H5">Warranty for cool spaces is the long term vision</h5> <p>Currently Chillservices saves around 3 to 5 % CO2<span> </span>with easy implemented measures while at the same time improving food security, but the Spin-Off is convinced that 30-40% efficiency improvement is possible in the very near future by providing all kind of integral services and products related to a warranty for cool spaces to supermarkets against the lowest possible costs. This will of course require substantial changes in today’s value chains and business models and extensive cooperation with partners from cooling cabinet manufacturers to energy suppliers. When overcoming these barriers substantial benefits could be unlocked by an overall optimization. This might be years in the future, but ChillServices is dedicated to play a part in this.<br /><br /></p> <h5 class="chalmersElement-H5">Clear path to expansion</h5> <p>Since supermarket chains constantly look for technologies meeting their sustainability strategies, ChillServices works on several activities in the upcoming period:</p> <ul><li>Fast implementation of SensorHold: goal for 2017 is 200 supermarkets with approx. 12,000 RDCs in Germany</li> <li>Acquire customer network – next markets: e.g. France and UK</li> <li>Implementation into the supermarket chain’s general sustainability strategy</li> <li>Solidify underlying business model</li> <li>Upscaling ChillServices in turnover, profits and team members<br /><br /></li></ul> <h5 class="chalmersElement-H5">Open innovation &amp; mutual trust</h5> <p>ChillServices is the Spin-Off of a co-creation process between Climate-KIC BTA and Chalmers University of Technology. It started in The Building Technology lab environment at Chalmers with the investigation into air flows around windows and doors. The team at Chalmers, created models and studied the results. Because of their relationship with REWE, they took their ideas to a new field – supermarkets – and applied it there. This now results in a perfect illustration of co-creation and open innovation, in a setting of mutual trust. Climate-KIC BTA supports this project with funds, knowledge &amp; experience and network.</p> <p>“It has been a joy to see these men developing their product and service, to assist them in building up their start-up and then to see their first impact. It is exactly what Europe needs: the smartest minds producing smart, solid solutions to tackle climate change.” – Zeno Winkels, Business Developer Climate-KIC BTA<br /><br /></p> <h5 class="chalmersElement-H5">About ChillServices</h5> <p><span>ChillServices ensures CO2 savings in the range of roughly 4-5 t CO2 eq. per market per year. The target is 200 supermarkets in 2017 and eventually all 8,000 supermarkets of the REWE group. Or in other numbers: at cost-benefit-ratio of 5 EUR/t CO2 eq. that stands for a potential EUR 312,500 savings per year for REWE under current emission certificate process and easily more than 1 million EUR per year based on the lowest projections from 2020.</span></p> <p><span>Besides indirect emission certificate savings the measures currently pay off directly by energy savings alone within around 2 years. As retail store installations have a life time of around 15 years this is more than attractive for supermarket owners.</span></p> <p><span>Finally, the measures contribute to more homogenous cooling of the goods stored in the cabinets adding to lifetime and quality of what is eventually the main purpose of a supermarket – selling food.<br /></span></p> <p><br /></p> <p><a href="http://bta.climate-kic.org/">Read more about the Climate-KIC BTA</a><br /><span></span></p> <p> </p> Sat, 10 Jun 2017 00:00:00 +0200http://www.chalmers.se/en/departments/mc2/news/Pages/New-video-with-Asa-Haglund-on-blue-lasers.aspxhttp://www.chalmers.se/en/departments/mc2/news/Pages/New-video-with-Asa-Haglund-on-blue-lasers.aspxNew video with Åsa Haglund on blue lasers<p><b>​Åsa Haglund, associate professor at the Photonics Laboratory at MC2, talks on her research on blue lasers in a new video published by the Swedish Foundation for Strategic Research (SSF).

The AHA festival at Chalmers gathers researchers, students and artists -  and invites the public to investigate the borders between science and art.</b></p>​This year, the theme is autonomy and the festival will take place at the Student Union building at Chalmers on 20-22 November. The program will be filled with public performances, lectures, workshops, exhibitions and seminar conversations.  It will be a melting pot for inquiring debates, dance, music, art, poetry, architecture and acrobatics. <p>“It is essential to have different perspectives and competences when facing the challenges in our society.

He warned to stereotypify people, but at the same time stressed that it is important to understand that stereotypes in fact exist.</b></p><div>​Jesper Fundberg is a senior lecturer in sports science at Malmö University, and a researcher in masculinity, sport, ethnicity and gender. About 60 participants gathered in the lecture hall Kollektorn on 30 March to listen to the invited guest and talk about the perspectives he highlighted.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/jfundberg_690x330_kollektorn.jpg" alt="" style="margin:5px" /> The initiative for the workshop came from Cristina Andersson, vice head of utilization and gender equality representative at MC2:</div> <div>&quot;The purpose of this event is to increase your awareness and willingness to discuss these issues in our own environment,&quot; she said briefly before she left the word to Jesper Fundberg.</div> <div> </div> <h4 class="chalmersElement-H4">Cowboys as an example</h4> <div>He began to establish that everything is all about power, and used cowboys from the wild west as illustrative examples:</div> <div>&quot;In that group it is the one who shoots fastest who has the power. But at the academy it's not as obvious. Here, instead, it's about being the one who has power over the agenda and about the issues discussed, the agenda power, said Jesper Fundberg.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/jfundberg_690x330_canyon.jpg" alt="" style="margin:5px" /> </div> <h4 class="chalmersElement-H4">Three strong standards</h4> <div>It was about men who take place, women who do not take place or who take place and are questioned for it. Here he had identified three strong standards:</div> <div>&quot;Men speak much more than women, but are often not aware of it. Have you ever heard a man say he is talking too much? Have you ever heard a woman say that? Men take time and place, a woman is cute, happy and caring. Why is not Angela Merkel happy? Why does she not look happy? It's actually a question discussed in Germany, but we never hear the same discussion about Donald Trump, said Jesper Fundberg.</div> <div> </div> <h4 class="chalmersElement-H4">Provoked</h4> <div>Some listeners were provoked by Jesper Fundberg and meant that he stereotyped people. Several gave him response and could tell about meetings with male students who did not take place, and female students who instead filled the room.</div> <div>- Of course, I do not talk about all men or all women. We are discussing patterns here today. One should be careful about stereotyping, while stereotypes actually exist,&quot; said Jesper Fundberg.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/jfundberg_sminkad_adjusted_220x180.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Heteronorm was another aspect raised. Fundberg showed two pictures of himself - one where he was wearing a suit and one where he wore women's clothes and was made up like a woman:</div> <div>&quot;When people do things outside the framework, they must immediately explain,&quot; he commented.</div> <div> </div> <div>At regular intervals, the lecture was broken by short two-minute discussions where participants were given an opportunity to discuss what they heard and ventilate their own experiences. Apparently these breaks were popular.</div> <div> </div> <h4 class="chalmersElement-H4">Easy to be a white middle-aged man</h4> <div>Fundberg found that it is easy to be in a masculine world, especially if you are a Swedish, white, middle-aged middle class man, and told how he is sometimes treated when he is lecturing:</div> <div>&quot;We do gender and generally believe that we in the academy are different and better. But people can come to me and say &quot;I listened to a female lecturer and did not mind at all, but now that I hear you say much the same things I think it's interesting!&quot;</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/jfundberg_kollage_full.JPG" class="chalmersPosition-FloatRight" height="200" width="300" alt="" style="margin:5px" />Women and men also tend to react in different ways, including within their respective genders.</div> <div>&quot;Women smile either blissfully and think &quot;he really tried to understand&quot; - or they are crossing their arms and think that the others only listen because I am a man and they discussed the same things for hundreds of years without results. Men usually have only one reaction - skepticism.</div> <div> </div> <h4 class="chalmersElement-H4">Male and female heads</h4> <div>In his research, among other things, Jesper Fundberg has investigated how male and female heads of departments are confirmed. Men often hear that they must continue their research in parallel with their assignment, and let others attend meetings because the male head can not take part in everything.</div> <div>&quot;Female heads, on the other hand, got the recommendation to quit their research because it was considered important to attend meetings to get information, and they can not do two things at the same time,&quot; said Fundberg.</div> <div> </div> <div><strong>Text and photo:</strong> Michael Nystås</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/jfundberg_690x330_fruktsallad.jpg" alt="" style="margin:5px" /> </div>Wed, 31 May 2017 09:00:00 +0200http://www.chalmers.se/en/departments/physics/news/Pages/Nanoalloys-ten-times-as-effective-as-pure-platinum-in-fuel-cells.aspxhttp://www.chalmers.se/en/departments/physics/news/Pages/Nanoalloys-ten-times-as-effective-as-pure-platinum-in-fuel-cells.aspxNanoalloys ten times as effective as pure platinum in fuel cells<p><b>​A new type of nanocatalyst can result in the long-awaited commercial breakthrough for fuel cell cars. Research results from Chalmers University of Technology and Technical University of Denmark show that it is possible to significantly reduce the need for platinum, a precious and rare metal, by creating a nanoalloy using a new production technique. The technology is also well suited for mass production.</b></p><div>​”A nano solution is needed to mass-produce resource-efficient catalysts for fuel cells. With our method, only one tenth as much platinum is needed for the most demanding reactions. This can reduce the amount of platinum required for a fuel cell by about 70 per cent”, says Björn Wickman, researcher at the Department of Physics at Chalmers. </div> <div> </div> <div>If this level of efficiency is possible to achieve in a fuel cell, the amount of required platinum would be comparable to what is used in an ordinary car catalytic converter. </div> <div> </div> <div>“Hopefully, this will allow fuel cells to replace fossil fuels and also be a complement to battery-powered cars”, says Björn Wickman. </div> <div> </div> <div>Even though there have been fuel cell cars for about fifty years, advances have not led to a commercial breakthrough. The catalysts in today’s fuel cells require large amounts of platinum, which is one of the world’s most expensive metals. </div> <div> </div> <div><img width="174" height="174" class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/legering_narbildI200x200MG_0737.jpg" alt="" style="margin:5px" />Previous research has shown that it is possible to mix platinum with other metals, such as yttrium, to reduce the amount of platinum in a fuel cell. Even so, no one has yet managed to create alloys with these metals in nanoparticle form in a manner that can be used for large-scale production. The major problem has been that yttrium oxidizes instead of forming an alloy with the platinum. </div> <div> </div> <div>This problem has now been solved by Chalmers researchers by combining the metals in a vacuum chamber using a technique called sputtering. The result is a nanometre-thin film of the new alloy that allows mass-produced platinum and yttrium fuel cell catalysts.</div> <div> </div> <div>To use the new material, today’s fuel cells need to change slightly, but doing so creates incredible opportunities.</div> <div> </div> <div>“When we can use our resources better, we save both the environment and lower costs. Fuel cells convert chemical energy into electrical energy using hydrogen and oxygen – with water as the only product. They have huge potential for sustainable energy solutions in transport, portable electronics and energy”, says Niklas Lindahl, researcher at the Department of Physics at Chalmers. <br /></div> <div><a href="http://onlinelibrary.wiley.com/doi/10.1002/admi.201700311/full">The results were recently published in the journal Advanced Materials Interfaces. </a> </div> <div> </div> <div>Text: Mia Halleröd Palmgren, <a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se</a> </div> <div> ​</div> <div><a href="http://www.mynewsdesk.com/uk/chalmers/pressreleases/nanoalloys-ten-times-as-effective-as-pure-platinum-in-fuel-cells-1982186"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /> Read the press release and download high resolution images. </a> </div> <div><img width="695" height="315" src="/SiteCollectionImages/Institutioner/F/750x340/nanokatalysator750x340.jpg" alt="" style="margin:5px" /> Image: Niklas Lindahl <br /></div> <h5 class="chalmersElement-H5">How the new method works: </h5> <div>Nanoalloys of platinum (grey) and yttrium (blue) are created using sputtering in a vacuum chamber.

What roles should various players take, and what are the challenges for those who take the lead? Chalmers invites you to a major conference on these questions in June.</b></p>​Nearly all the countries in the world have subscribed to the vision of a sustainable future. But how do we achieve it? What obstacles are in the way? What roles should various players have, and how do we make the transition go fast enough? <br /><br />These are the kinds of questions that transition researchers focus on. In June, many such researchers will gather in Gothenburg when Chalmers hosts the 8th International Sustainability Transitions Conference.<br /><br />“The conference focuses on the leadership and learning needed to speed up the transition to a sustainable society,” says Hans Hellsmark, transition researcher at Chalmers and coordinator of the conference.<br /><br />In addition to researchers, the conference is also for government agencies and ministries, organisations working towards the UN’s Sustainable Development Goals and companies that want to take the lead in sustainability transitions. The conference will feature over one hundred sessions under eleven themes, including leadership; entrepreneurship; urban, regional and corporate transitions; policy instruments and politics.<br /><br />“Our dialogue sessions are probably especially exciting for non-academics,” Hellsmark says. “They involve interaction between different players, making a point of collaboration and learning from each other. Monday’s panel discussion on political leadership and scientific knowledge in sustainable transitions also looks to be really exciting.”<br /><br />The keynote speakers are typical high points of any conference. They include Peter Senge from the MIT Sloan School of Management, who wrote the bestselling book The Fifth Discipline. He will be talking about what kind of leadership is required in sustainability transitions, and the challenges to different organisations when taking the lead.<br /><br />“The conference can give valuable insights into everything from the importance of grassroots involvement to the most effective policy instruments,” Hellsmark says. “And of course it’s a great opportunity to make good connections.”<br /><br />For Chalmers, the conference is an opportunity to showcase its strong research environment in the field of sustainability transitions. The researchers come from a variety of disciplines and are united under <a href="/en/areas-of-advance/energy/joint_initiatives/Pages/Chalmers-Initiative-in-Innovation-and-Sustainability-Transitions.aspx">Chalmers Initiative for Innovation and Sustainability Transitions</a>.<br /><br />The conference will be held on 18–21 June.
