Thanks to an algorithm developed at Chalmers University of Technology, information from the sensors in the motorcyclist’s mobile phone can be used to identify that an accident has occurred and automatically call for help via SOS Alarm.</b></p>​<span style="background-color:initial">Motorcyclists are exposed and unprotected in traffic compared to most road users. Every year, around 250 drivers are seriously injured in Sweden, according to statistics from the Swedish Transport Agency. The trend is increasing – in 2018, 47 motorcyclists was killed, which is the highest rating in ten years.</span><div><br /></div> <div>”If a single vehicle accident occurs and the driver ends up unconscious in the ditch, it may take a long time before anyone notices what has happened”, says Chalmers researcher Stefan Candefjord, being a biker himself, and also one of the originators of the algorithm that is now used by SOS Alarm in a pilot project.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Appen%20som%20själv%20larmar%20vid%20en%20mc-olycka/Stefan_och_BAS_500px.jpg" class="chalmersPosition-FloatLeft" alt="Stefan Candefjord and Bengt Arne Sjöqvist" style="margin:5px" /><em>T</em><em>he researchers Stefan Candefjord and Bengt Arne Sjöqvist have developed the algorithm that makes it possible to automatically trigger an alarm to SOS Alarm, via an app in the mobile phone, in the event of a motorcycle accident. The sensor alarm technology could also be used for other unprotected road users such as horse riders and all-terrain vehicle drivers.</em></div> <div><i><br /></i></div> <div><br /></div> <div><strong><br /></strong></div> <div><strong><br /></strong></div> <div><strong>Fast and safe help for unprotected road users</strong></div> <div>Stefan Candefjord and Bengt Arne Sjöqvist, who both do research at the department of Electrical Engineering, are active in the field of prehospital e-health/Digital Health. The research is about developing smart IT solutions as support for decisions, aiming at to provide the right care and prompt treatment, even before the patient is brought to hospital. In this case, it is important to rapidly detect that an accident has occurred to alert the right rescue resources and thus minimizing injuries and deaths.</div> <div><br /></div> <div>“Our starting point was to develop a function that is similar to eCall, which modern cars of today are equipped with, though instead directed to unprotected road users”, says Bengt Arne Sjöqvist. “The advantage of a mobile app is that it is considerably easier to distribute to the users than a specially designed hardware would be – since a smartphone already is present in almost every person's pocket.”</div> <div><br /></div> <div>Initially, the intended target group was single practitioners such as cyclists, horse riders and all-terrain vehicle drivers. In 2017, the researchers got in touch with a group of master’s students via Chalmers Ventures, who signed up for the idea. The company Detecht was founded with a focus on motorcycle drivers – a homogeneous target group with similar interests and a high safety awareness, that the app can satisfy.</div> <div><br /></div> <div>“The two of us and Detecht are complementing each other. They are knowledgeable in the field and are driving the business model, while we can concentrate on the actual research part of the project,” says Stefan, who also holds a seat in the company board and will continue to contribute to the development of the functions of the algorithm.</div> <div><br /></div> <div>For his part, Bengt Arne works within the framework of the &quot;Prehospital ICT Arena&quot;, with a related research project called TEAPaN (Traffic Event Assessment, Prioritizing and Notification). The purpose is to establish an IT structure that, in a coordinated way, is able to connect various eCall solutions – the motorcycle app being one of several examples – with the society's rescue resources so that they are prioritized correctly, and the effort is optimized based on what actually has happened.</div> <div><br /></div> <div>In addition to the safety aspect, the app also offers the users some social features such as sharing routes, pictures and statistics with other motorcyclists. This is something that hopefully makes the app even more interesting to use. In Sweden alone, there are more than 300 000 registered motorcycles, and internationally the interest is also very widespread – the market is considered to be substantial.</div> <div><br /></div> <div><strong>Being tested by SOS Alarm and 15 000 bikers</strong></div> <div>For three months, including May with a possibility of an extension, the app is tested in a pilot project at SOS Alarm.</div> <div><br /></div> <div>“SOS Alarm is usually being restrictive in integrating new functions into their system, so it is gratifying that they are welcoming this technology and want to evaluate how sensor-controlled alarms can aid in their work”, Bengt Arne says.</div> <div><br /></div> <div>Nor has it been difficult to recruit motorcycle drivers who want to take part in the test.</div> <div><br /></div> <div>“The test results for April show that the about 15 000 motorcyclists involved in the project altogether have driven 120 000 kilometers, corresponding to three laps around the globe. One single minor accident did occur. The crash was correctly detected, the alarm was triggered as planned, and the operator at SOS Alarm sent intended rescue units to the position of the accident”, Stefan says.</div> <div><br /></div> <div>“The number of false alarms has been low, only once was the alarm released unjustified. One possible reason is that the driver probably had the phone lying loosely during the ride, which may have affected the data that the app registered and therefore incorrectly was interpreted as if the motorcycle overturned at speed. We will analyze all such events to decide what further improvements in the algorithm that can be made.”</div> <div><br /></div> <div>In the future, functions based on artificial intelligence are planned to be integrated, which will enhance the motorcyclists’ experiences. For example, the app can then recommend roads, fika stops and driving routes based on previous choices and preferences of the driver.</div> <div><br /></div> <div>From a societal perspective, it is the possibility to save lives that is the crucial factor. The time that elapses from the occurrence of an accident until the victims get help can be directly decisive for the outcome. In addition to providing increased safety for the driver, the app is also giving reassurance for family and friends, who quickly can get a notice about an accident.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Appen%20som%20själv%20larmar%20vid%20en%20mc-olycka/5-Mockups-midle-min_750px.jpg" class="chalmersPosition-FloatLeft" alt="Features from mororcycle app" style="margin:5px" /><br /><br /><br /></div> <div><br /></div> <div><strong>This is how the app works</strong></div> <div>The mobile phone's built-in sensors record speed, g-force and rotation. The information from the run is analyzed using an algorithm that identifies driving behavior that indicates that the driver is no longer in control of the motorcycle. If the alarm is activated, the driver has 60 seconds to turn off the alarm, otherwise, an alarm message is automatically triggered, contacting SOS Alarm with information about the position. Then, the alarm operator first tries to establish contact with the driver over the phone. If the driver is in need of assistance, alternatively is not contactable, rescue units are alerted to the current location.</div> <div>Basically any smartphone can be used, the only requirement is that the driver downloads and activates the app &quot;Detecht – your motorcycle app&quot;. Anyone interested can participate as a test driver.</div> <div><br /></div> <div>Text: Yvonne Jonsson</div> <div>Photo: Detecht and Yvonne Jonsson (portrait photo)</div> <div><br /></div> <div><a href="https://www.detecht.se/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more about Detecht – Automatic Crash Detection for Motorcyclists</a><br /></div> <div><br /></div> <div><a href="https://www.sosalarm.se/pilotprojekt-sensorlarm-mc/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more on SOS Alarm´s webpage (in Swedish): Pilotprojekt för sensorlarm vid mc-olyckor​</a><br /></div> <div><br /></div> <div><br /></div> <div><div><strong>For more information please contact:</strong></div> <div><a href="/en/staff/Pages/stefan-candefjord.aspx">Stefan Candefjord</a>, Assistant Professor in the Biomedical electromagnetics research group, Department of Electrical Engineering, Chalmers University of Technology, <a href="mailto:%20stefan.candefjord@chalmers.se">stefan.candefjord@chalmers.se</a></div> <div><br /></div> <div><a href="/en/staff/Pages/bengt-arne-sjoqvist.aspx">Bengt Arne Sjöqvist,</a> Associate Professor and former Professor of Practice in the Biomedical signals and systems research group, <a href="mailto:%20bengt.arne.sjoqvist@chalmers.se">bengt.arne.sjoqvist@chalmers.se</a>, and Programme Manager for <a href="https://picta.lindholmen.se/en" target="_blank">Prehospital ICT Arena (PICTA) at Lindholmen Science Park​</a></div></div> <div><br /></div> Thu, 16 May 2019 12:30:00 +0200https://www.chalmers.se/en/departments/physics/news/Pages/A-big-celebration-of-new-research-possibilities.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/A-big-celebration-of-new-research-possibilities.aspxAn international celebration of new research possibilities<p><b>​Chalmers&#39; new electron microscope enables researchers to study and design the smart materials of the future.

I know that this award is bestowed to a single person every year and that makes me feel humble and grateful. Most of the work is still ahead of us, but this award encourages me and all of our team to carry on.”</div> <div><br /></div> <div>Francesco Gatto was PhD student at the Department of Biology and Biotechnology at Chalmers between 2012 and 2015, where he was part of the Nielsen lab. In 2015 he started a project together with Professor Jens Nielsen. After the venture was incubated within Chalmers innovation systems, they founded the company Elypta in 2017.</div> <div>“To be fair, it was Jens who pushed me to give entrepreneurship a try”, says Francesco Gatto, who now is Chief Scientific Officer at Elypta, responsible for the tasks of executing product development, clinical studies, and compliance to regulations.</div> <div><br /></div> <div><strong>Detection as well as follow-up</strong></div> <div>Francesco Gatto works with preventing cancer mortality by developing the technique of liquid biopsies from blood or urine for detection as well as follow-up, since the test findings also show how the patient responded to treatment. The technology is based on 19 biomarkers, which Francesco Gatto identified during his time as a doctoral student at Chalmers. The use of machine learning-based algorithms then helps to detect the presence of cancers from the biomarker measurements.</div> <div>“A timely diagnosis of cancer is absolutely crucial in some cases to provide the most effective treatments to patients. Many times, we have ineffective ways to know if you are responding properly to a certain therapy, or if cancer has come back after curative surgery. At Elypta, we are developing a novel test to detect cancer in blood and urine samples by measuring this new class of biomarkers. We discovered these biomarkers thanks to our research at Chalmers in Jens Nielsen lab around how cancer regulates its metabolism.”</div> <div><strong>How can this be used in a practical manner?</strong></div> <div>“Our initial objective is to help patients with kidney cancer. Today, kidney cancer is diagnosed relatively early and patients are fit for surgery and often able to live a normal life. However, some 20% of them experiences recurrence of the cancer within 5 years. The earlier we detect the recurrence, the more options for curative therapy exist. The current follow-up plan consists solely of medical imaging scans every 6-12 months. We want to complement this with our blood/urine test every 3 months. If our test is positive, the patient should be scheduled for an earlier image scan than first planned, and hopefully a recurrence is detected on time”.</div> <div><br /></div> <div><strong>What is important to you in your scientific work?</strong></div> <div>Data talks – this is the number one take-away from science. Science also is the way we adopted for our business. We strive to take all our decisions in an analytical data-driven manner. Of course, this takes time, but it minimizes regret. </div> <div><strong>What lies ahead of you in the near future?</strong></div> <div>“To keep working. It is a long path – but I will not be happy until we can provably show that we helped at least 1 patient.”</div> <div><br /></div> <div>Francesco Gatto is awarded Karin Markides Innovation Award at Chalmers PhD at May 18th.</div> <div><br /></div> <div><a href="/sv/om-chalmers/akademiska-hogtider/promotion/innovationspriset/Sidor/default.aspx">Former award winners are found here.​</a></div> <div><br /></div> Mon, 13 May 2019 15:30:00 +0200https://www.chalmers.se/en/departments/math/news/Pages/Statisticians-requested-in-medicine.aspxhttps://www.chalmers.se/en/departments/math/news/Pages/Statisticians-requested-in-medicine.aspxStatisticians requested in medicine<p><b>​Staffan Nilsson has been working with medical statistics a long time. Today he is employed half-time at the Department of Mathematical Sciences and half-time at the Sahlgrenska Academy.</b></p><p><img class="chalmersPosition-FloatLeft" alt="Staffan Nilsson" src="/SiteCollectionImages/Institutioner/MV/Nyheter/staffannilsson250x300.jpg" style="margin:5px" />– Being a statistician is, contrary to what many people believe, a very social profession. To be able to do a good job, a good contact with the experts in the field where the statistics are to be applied is needed, which requires social competence and that the prestige can be put aside. </p> <p>Staffan has been involved in countless medical research projects during the years and has co-authored 200 articles. In the projects, he is often co-supervisor of a PhD student from the Sahlgrenska Academy. Right now he is completing a major work on meta-analyses of SSRI antidepressant drugs. The value of these drugs has been strongly questioned from some quarters, and together with Elias Eriksson and Fredrik Hieronymus at the Department of Pharmacolocy, Staffan has made a thorough review of the medicines’ effectiveness. The conclusion is that they are better than what has been previously thought.</p> <p>A recently started project is about retina disease as a result of premature birth. The eye develops late and premature babies risk becoming blind, the project is about being able to predict as well as possible which children will need treatment. Here, Staffan supervises a statistician, Aldina Pivovic, together with Ann Hellström at the Queen Silvia Children’s Hospital. They use methods for survival statistics developed by Anders Odén, who defended his PhD thesis at the Department of Mathematical Sciences in 1977, and the project also includes a thorough documentation of these methods.</p> <h2>Genetics, new and hot in the 90s</h2> <p>When Staffan at the age of 40 switched from being a computer consultant to a PhD student in mathematical statistics, the idea to work with medical applications one day was already there, his wife and several of his friends are doctors. Yet it was a coincidence that Jan Wahlström, professor of clinical genetics, contacted Mathematical Sciences at that time, and that Staffan’s PhD project came to be about genetics. After that, the collaboration with Sahlgrenska has just continued.</p> <p>– An early highlight was to be involved as an expert in the parliamentary inquiry in genetic integrity that was made at the time, I was there as a counterweight to the insurance companies, and it was very fun and different.</p> <p>During the Wallenberg initiative Swegene between the years 2003 and 2007 Staffan was the director of the division Bioinformatics, and that together with being responsible for the statistics education for the PhD students at Sahlgrenska during many years has been the basis for a large contact network. When the Swegene initiative ended many people wanted to continue the collaboration, which formed the basis of an agreement between the departments for ten years, replaced by today’s 50/50 employment a few years ago.</p> <h2><img class="chalmersPosition-FloatRight" alt="Staffan Nilsson, Martina Olsson Lindvall, Sofia Klasson" src="/SiteCollectionImages/Institutioner/MV/Nyheter/medicinskstatistik350x305.jpg" style="margin:5px" />The need for statisticians is great</h2> <p>– I have enjoyed these years very much, I like to work with people and I am no good at saying no. I have worked with genetics studies of celiac disease, MS, Parkinson’s, Alzheimer’s, stroke, breast cancer, colon cancer, neuroblastoma etc., but also with HIV and other infectious diseases. In recent years, I have also been involved in several projects related to premature childbirth where we sometimes use registry data. It is this variation, from large registry studies to small experimental experiments with cell lines, that is so appealing.</p> <p>Staffan is often asked questions like “do you have any statistician who could work in my project?”. Although there are already many statisticians at Sahlgrenska today, the need is even greater. A new course starts this autumn where statistical students study together with PhD students at Sahlgrenska, all with a project that includes the need for knowledge in statistics. The course is called Logistic regression and survival analysis, but the idea could be applied to several courses according to Staffan.</p> <p>– It is important to get the possibility to try the reality during the education, that the statisticians meet practical problems and future customers. In Gothenburg there are pharmaceutical companies, biotech companies and a large medical faculty, and many of those who will work with statistics in this city will end up in the medical sphere. <br /><br /><strong>Text and portrait photo</strong>: Setta Aspström<br /><strong>Photo</strong>: Ewa-Lotta Kärrstedt.

For this, Professor Lisbeth Olsson receives over SEK 14 million from the Novo Nordisk Foundation.</b></p>​The news came a few days ago: Lisbeth Olsson receives the prestigious grant as Distinguished Investigator from the Danish founding agency Novo Nordisk Foundation, NNF. The grant is given to established and senior researchers, who do pioneering research in biotechnology, and it entails a total of 14.3 million SEK over five years.<br /><br />“This feels great. The NNF grant makes it possible for me to focus, with a large project that go into depths of my research,” says Professor Lisbeth Olsson, also Head of the division of Industrial Biotechnology at Chalmers Department of Biology and Biological Engineering.<br /><br />“I will hire two doctoral students and a post-doc in this project, and expect them to join us this fall.”<br /><br /><strong>Environmentally friendly production with microorganisms<br /></strong><br />Microorganisms can produce many of the substances we need – like bioethanol, plastics and pharmaceutical proteins – using, for example, biomass as raw material. But when the microorganisms are removed from their natural habitat to work in another environment, they may become stressed. This stress causes damage to the cell, and its attempt to repair the damage costs a lot of energy. Ultimately, the production capacity of the microorganisms, or even their survival ability, will be at stake.<br /><br />Further knowledge is therefore needed to start new industrial processes where microorganisms are used, and also to streamline existing processes. The researchers want to find out how the microorganisms can become more robust, to withstand challenging environmental conditions.<br /><br />“As I first came to Chalmers, 11 years ago, I defined microbial robustness as one of the areas where I wanted to focus. Over the years, we have also had a number of doctoral students working with this. Now it’s time to further develop the concept,” says Lisbeth Olsson.<br /><br />“We will use large-scale tools, and take advantage of biodiversity existing in nature, as well as the one we have created in our lab. Our methods will be new, while taking advantage of the research we have done before. This will be &quot;microbial robustness 2.0&quot;. Previously, we have also focused mainly on biomass. Now, we are working with a more generalized technology.”<br /><br /><strong>Writing about biotechnology<br /></strong><br />The researchers' work while seeking grants means putting a lot of thought into every relevant problem, Lisbeth Olsson says.<br /><br />“For each grant application you twist and turn your research issues, and dwell on the relevant questions. It is great to have received this grant – now I have the opportunity to realize what’s been on my mind.”<br /><br />She is working in parallel with editing and writing chapters of a book on biofuels, where a chapter also is devoted to microbial robustness. This will be a follow-up to a book that came out ten years ago.<br /><br />“It is really exciting to work with colleagues around the world, and reflect on the learnings from developing this research area in recent years,” Lisbeth Olsson concludes.<br /><br />Note: Read more about the Research Leader Programme at Novo Nordisk Foundation <a href="https://researchleaderprogramme.com/">here</a>.

The hearing aid utilizes the ability of bone to transmit vibrations in the body, thus creating an alternative path for the sound to travel to the inner ear, via bone instead of air.</div> <div><br /></div> <div>“Initially, there were a lot of people, both in academia and in industry, who were hesitant about the benefits of the technology and gave us the advice to devote ourselves to something else”, Bo Håkansson says. “However, we were convinced that the idea had a future, and eventually we succeeded in gaining acceptance for it.”</div> <div><br /></div> <div>It took almost 15 years before the healthcare system began to use hearing aids based on bone conduction attached to the done directly. Since then the Gothenburg region has become somewhat of a center for companies engaged in that kind of hearing products.</div> <div><br /></div> <div>The diagnosis of dizziness is another promising research area where the bone conduction technology also can be used. Bo Håkansson and his research colleagues at Chalmers have developed a new type of bone conduction transducer to make diagnoses more accurate in a way that is also more comfortable for the patient.

The purpose is to raise the level of awareness about the whole Agenda 2030 and to strengthen users&#39; contributions to sustainable development.</b></p><div><div>The tool is called the SDG Impact Assessment Tool and is developed by the Gothenburg Center for Sustainable Development at Chalmers University of Technology and the University of Gothenburg, in collaboration with SDSN Northern Europe and Mistra Carbon Exit, and with financial support from the Region Västra Götaland via the Maritime Cluster of Western Sweden.</div> <div><br /></div> <div>The Gothenburg Center for Sustainable Development is the owner of the tool. Director Jan Pettersson says that this is a very important asset, initiated for researchers and other actors to be able to work with and relate to the Global Goals in their own business.</div> <div><br /></div> <div>– We want to offer a tool to strengthen the work on sustainable development within research, education, and collaboration within both Chalmers and the University of Gothenburg. But the tool is not just for the universities. It is also valuable for all types of businesses that want to strengthen their contribution to the Global Goals.</div> <div><br /></div> <div>The tool is free and available online for anyone to use. The base for the tool is a method that has been used previously but then only in a paper format. By launching a web version of the tool, the project manager Anders Ahlbäck hopes to reach more people with the message that a holistic view of the Global Goals is important.</div> <div><br /></div> <div>– Today, many businesses spend time selecting &quot;their&quot; goals in Agenda 2030, often through mapping. With the SDG Impact Assessment Tool, we try to reverse the perspective. The tool offers a structured way to describe the impact on the Global Goals, based on the users’ own knowledge. Do we have positive, negative or no impact on a goal? Do we know, or do we lack knowledge? By thinking about these issues, we hope that users can strengthen their contributions to Agenda 2030 and the Global Goals for sustainable development.</div> <div><br /></div> <div>There are many ways to address the Global Goals and the tool reflects that fact. Depending on how the user defines the purpose of making an assessment in the tool, it can fulfill different objectives. Some examples are: to identify risks and opportunities related to the Global Goals; to set own goals adapted to sustainable development; to tell shareholders and other stakeholders about what impact one's business has; or to engage all employees in promoting the goals and allocating responsibility across the organization to achieve progress. All these variants differ in mindset – but differences can also be turned into coherence.</div> <div><br /></div> <div>– If, for example, several municipalities, county councils and regions use the tool in the same way, it will be easier to achieve consensus on common challenges, says Anders Ahlbäck.</div> <div><br /></div> <div><br /></div> <div>To access the web tool, just follow the <a href="https://sdgimpactassessmenttool.org/">direct link to the SDG Impact Assessment Tool</a> and create a user account.</div> <div><br /></div> <div>More information on assessments regarding the Global Goals for sustainable development can be found on the <a href="https://www.unsdsn-ne.org/our-actions/initiatives/sdg-impact-tool/">SDSN Northern Europe website​</a>.</div> <div><br /></div></div> <div><br /></div> <div><em style="background-color:window;font-size:8pt">By: Nina Silow</em><br /></div>Mon, 06 May 2019 17:00:00 +0200https://www.chalmers.se/en/news/Pages/Anniversary-for-the-periodic-table.aspxhttps://www.chalmers.se/en/news/Pages/Anniversary-for-the-periodic-table.aspxAnniversary for the periodic table<p><b>​The periodic table turns 150 this year and with that the UN has declared 2019 as the year of the periodic table.</b></p><p>​<span style="background-color:initial">It was the Russian scientist Dmitrij Mendelejev who in 1869 took the at the time known elements and structured them.

She is also a role model and committed to gender equality. For this, Pernilla Wittung-Stafshede receives the Gustaf Dalén medal.</b></p><p>​“This feels great, and I am incredibly honored to get this attention from the Chalmers Alumni Association. Previous recipients of this medal are mostly older men, with successful business carriers; out of 51 medalists, only three are women. I hope the fact that I get this medal will motivate young women to study at Chalmers, and that it highlights academia as an exciting and extremely rewarding career path,” says Pernilla Wittung-Stafshede, the recipient of the Gustaf Dalén medal 2019, and continues:<br /><br />“Chalmers has shaped me, as I became an adult during my studies here. This was the best years of my life. I found “my thing” in research, and I made friends for life. I have also kept in touch with Chalmers even as I worked in the US for many years. I was head of US Friends of Chalmers for some time, and me and my husband arranged a spring meeting with party in New Orleans for the Chalmers Alumni Association’s US division.”<br /><br />Pernilla Wittung-Stafshede, who is a professor of chemical biology working at Chalmers’ Department of Biology and Biological Engineering, has received numerous awards over the past couple of years.<br /><br /><strong>You're an established researcher. Is it still important for you to win awards?</strong><br /><br />“Yes. I doubt my ability all the time, and awards are a way to help boost the self-confidence,” she says.<br /><br />Pernilla Wittung-Stafshede’s research focuses on proteins, that perform all the work in our bodies. The proteins have to fold correctly in order for them to fulfill their task. When they misfold, they malfunction – and this could result in diseases such as Parkinson’s or Alzheimer’s.<br /><br />Wittung-Stafshede has also taken an interest in metal ions, and the transport of such inside human cells. By building from basic knowledge concerning protein folding and metal dependent protein functions, it may be possible to understand the cause of diseases and lay the ground for future new treatments.<br /><br /><strong>What makes research so rewarding?</strong><br /><br />“It’s a thrill to discover completely new things, finding connections that no one has seen before. And I want to help humanity by understanding how the body works, as well as what goes wrong when you get sick.”<br /><br /><strong>You spend a lot of time working with gender equality issues, as Head of Chalmers gender equality initiative, Genie. Which of your tasks is most interesting?</strong><br /><br />“We have a lot of interesting things going on in the lab right now. We hope to close in on solutions to Parkinson’s and cancer in the coming years. Now with me focusing lots of attention on gender equality work, my students get more freedom to work independently,” Pernilla Wittung-Stafshede says.<br /><br />“Gender equality is such an important task, and it is very rewarding to learn how to work on a larger scale. There are so many new challenges. To get action, someone has to take the driver seat, and I'm now experienced enough to dare do that. I hope Genie can initiate lasting change at Chalmers.”<br /><br /><strong>In 25 years from now: What do you hope to see in your rearview mirror?</strong><br /><br />“I want to make a difference. When I look back, I want to feel pride in that I did all I could. I also hope that I have been a role model for younger people and given them courage to go far. It is important to remember that you do not have to be perfect. Nobody is! I have my shortcomings like everyone else.”<br /><br />The Gustaf Dalén medal will be given to Pernilla Wittung-Stafshede on the Chalmers Alumni Association’s spring meeting in Gothenburg, on May 11.<br /><br />Read the <a href="/sv/institutioner/bio/nyheter/Sidor/Pernilla-Wittung-Stafshede-arets-Gustaf-Dalen-medaljor.aspx">full motivation by the Alumni Association in Swedish here</a>.<br /></p> <p>Text: Mia Malmstedt<br />Photo: Oscar Mattsson</p>Thu, 02 May 2019 10:00:00 +0200https://www.chalmers.se/en/news/Pages/Areas-of-Advance-Award-given-to-research-exploring-the-structure-of-proteins.aspxhttps://www.chalmers.se/en/news/Pages/Areas-of-Advance-Award-given-to-research-exploring-the-structure-of-proteins.aspxAreas of Advance Award for exploring the structure of proteins<p><b>​This year&#39;s Areas of Advance Award is given for the development of a unique method of analysing the structure and chemical composition of proteins. Increasing our knowledge of proteins could yield many advances, including the development of new and more effective drugs.</b></p>​The Areas of Advance Award this year goes to Martin Andersson, Pernilla Wittung Stafshede and Fredrik Höök, who combined materials analysis with biology using a clear multidisciplinary approach.<br /><br />“It is very encouraging to have our work highlighted in this way,” says Martin Andersson, who first initiated the research project.<br /><br />He contacted Pernilla Wittung Stafshede and Fredrik Höök to combine research expertise from the three departments of Chemistry and Chemical Engineering, Biology and Biological Engineering and Physics. The aim of the project is to develop a unique method for studying proteins, and thereby open up new knowledge and greater understanding of their functions.<br /><br /><strong>High resolution analysis</strong><br />An important group of proteins, especially when it comes to development of pharmaceuticals, are those found in the membrane of cells. About 60 percent of all pharmaceuticals target membrane-bound proteins, directly or indirectly, which shows their great importance. <br /><br />However, due to these proteins’ need for the cell membrane environment, it is difficult to analyse their structure with established methods, such as X-ray crystallography, magnetic resonance imaging or cryo-electron microscopy.<br /><br />The current project makes use of Atom Probe Tomography instead, with which both the structure and chemical composition of proteins can be observed. The technology offers enormous precision. At present the researchers have shown that it is possible to determine the structure of individual proteins with approximately 1 nanometre resolution. However, the challenge lies in designing a sample preparation method that makes the process faster, and allows to focus on individual proteins, which is the focus of the collaboration.<br /><br />“We still have a lot to learn about proteins, such as those that contribute to ‘misfolding’ diseases like Parkinson's and Alzheimer's. The proteins involved here are very flexible and begin to clump together during illness, but we do not know why and how because they are difficult to study with other methods,” says Pernilla Wittung Stafshede.<br /><br /><strong>New use of an established method</strong><br />Atom Probe Tomography is a well-established technology, but it has mainly been used previously to characterise metals and other hard materials. Applying the method to biological materials, especially proteins, shows an innovative approach. The researchers have continued work to develop and adapt the sample preparation process.<br /><br />“Our project can be described as high-risk – we do not yet know if it will be successful. But if we do succeed, it could potentially be of huge benefit. Getting the Areas of Advance Award is a strong encouragement to continue,” says Fredrik Höök, Professor of Physics.<br /><br />The current project has been financed by the Materials Science Area of Advance.<br />“It is very valuable that Chalmers' Areas of Advance can offer support for early testing of our idea. We need to be able to show preliminary results in order to successfully seek funds from external donors,” says Martin Andersson.<br /><br />Now, the first scientific article has been accepted, and the three researchers hope to expand the project going forward. A first application was made a couple of years ago but was rejected.<br /><br />“But now we have shown that the method works! Sometimes one has to ignore some of the accepted expertise and go on intuition. And then you have to have the opportunity to experiment,” says Martin Andersson.<br /><br /><div><br /> </div> <div><em>Text: Malin Ulfvarson</em></div> <div><em>Photo: Johan Bodell</em></div> <div><br /> </div> <strong>The Areas of Advance Award</strong><br />With the Areas of Advance Award, Chalmers looks to reward those who have made outstanding contributions to cross-border collaborations and who, in the spirit of the Areas of Advance, integrate research, education and utilisation.

One option is lithium sulphur batteries, which offer a theoretical energy density roughly five times that of lithium ion batteries. Researchers at Chalmers University of Technology, Sweden, recently unveiled a promising breakthrough for this type of battery, using a catholyte with the help of a graphene sponge. ​​​</b></p><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Graphene%20aerogel%20toppbild%202.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;height:181px;width:250px" /><div><span style="background-color:initial">The researchers’ novel idea is a porous, sponge-like aerogel, made of reduced graphene oxide, that acts as a free-standing electrode in the battery cell and allows for better and higher utilisation of sulphur. <br /></span><br /></div> <div>A traditional battery consists of four parts. First, there are two supporting electrodes coated with an active substance, which are known as an anode and a cathode. In between them is an electrolyte, generally a liquid, allowing ions to be transferred back and forth. The fourth component is a separator, which acts as a physical barrier, preventing contact between the two electrodes whilst still allowing the transfer of ions. <br /><br /></div> <div>The researchers previously experimented with combining the cathode and electrolyte into one liquid, a so-called ‘catholyte’. The concept can help save weight in the battery, as well as offer faster charging and better power capabilities. Now, with the development of the graphene aerogel, the concept has proved viable, offering some very promising results. <br /><br /></div> <div>Taking a standard coin cell battery case, the researchers first insert a thin layer of the porous graphene aerogel.</div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Carmen%20Cavallo.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:250px;height:218px" />“You take the aerogel, which is a long thin tube, and then you slice it – almost like a salami. You take that slice, and compress it, to fit into the battery,” says Carmen Cavallo of the Department of Physics at Chalmers, and lead researcher on the study. <br /><span style="background-color:initial">Then, a sulphur-rich solution – the catholyte – is added to the battery. The highly porous aerogel acts as the support, soaking </span><span style="background-color:initial">up the solution like a sponge. </span><br /></div> <div>“The porous structure of the graphene aerogel is key. It soaks up a high amount of the catholyte, giving you high enough sulphur loading to make the catholyte concept worthwhile. This kind of semi-liquid catholyte is really essential here. It allows the sulphur to cycle back and forth without any losses. It is not lost through dissolution – because it is already dissolved into the catholyte solution,” says Carmen Cavallo. <br /><br /></div> <div>Some of the catholyte solution is applied to the separator as well, in order for it to fulfil its electrolyte role. This also maximises the sulphur content of the battery. </div> <div>Most batteries currently in use, in everything from mobile phones to electric cars, are lithium-ion batteries. But this type of battery is nearing its limits, so new chemistries are becoming essential for applications with higher power requirements. Lithium sulphur batteries offer several advantages, including much higher energy density. The best lithium ion batteries currently on the market operate at about 300 watt-hours per kg, with a theoretical maximum of around 350. Lithium sulphur batteries meanwhile, have a theoretical energy density of around 1000 to 1500 watt-hours per kg. </div> <div><br /><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Aleksandar%20Matic.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;height:218px;width:250px" />“Furthermore, sulphur is cheap, highly abundant, and much more environmentally friendly. Lithium sulphur batteries also have the advantage of not needing to contain any environmentally harmful fluorine, as is commonly found in lithium ion batteries,” says Aleksandar Matic, Professor at Chalmers Department of Physics, who leads the research group behind the paper. <br /><br /></div> <div>The problem with lithium sulphur batteries so far has been their instability, and consequent low cycle life. Current versions degenerate fast and have a limited life span with an impractically low number of cycles. But in testing of their new prototype, the Chalmers researchers demonstrated an 85% capacity retention after 350 cycles. <br /><br /></div> <div>The new design avoids the two main problems with degradation of lithium sulphur batteries – one, that the sulphur dissolves into the electrolyte and is lost, and two, a ‘shuttling effect’, whereby sulphur molecules migrate from the cathode to the anode. In this design, these undesirable issues can be drastically reduced. </div> <div><br /></div> <div><span style="background-color:initial">The researchers note, however, that there is still a long journey to go before the technology can achieve full market potential. <br />&quot;Since these batteries are produced in an alternative way from most normal batteries, new manufacturing processes will need to be developed to make them commercially viable,&quot; says Aleksandar Matic.<br /></span><br /></div> <div><span style="background-color:initial">Text: Joshua Worth,<a href="mailto:%20joshua.worth@chalmers.se"> joshua.worth@chalmers.se</a></span></div> <div><span style="background-color:initial">Images: Johan Bodell, <a href="mailto:%20johan.bodell@chalmers.se​">johan.bodell@chalmers.se</a></span></div> <div><span style="background-color:initial"><br /></span></div> <div>Read the article,<a href="https://www.sciencedirect.com/science/article/pii/S0378775319300916?via%3Dihub"> “A free-standing reduced graphene oxide aerogel as supporting electrode in a fluorine-free Li2S8 catholyte Li-S battery,”</a> published in the Journal of Power Sources. ​<span style="background-color:initial"><br /></span></div> <div><h3 class="chalmersElement-H3" style="font-family:&quot;open sans&quot;, sans-serif"><img src="/SiteCollectionImages/Institutioner/F/750x340/Graphene%20Aerogel%20Toppbild.jpg" alt="" style="font-size:14px;font-weight:300;margin:5px" />​​​​<span style="background-color:initial;color:rgb(51, 51, 51);font-family:&quot;open sans&quot;, sans-serif;font-size:14px;font-weight:300">The reduced graphene oxide aerogel developed by the researchers, that makes the catholyte concept viable.</span></h3></div> <div>​<br /><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">M</span><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:16px;font-weight:600;background-color:initial">ore about the Chalmers lab used in this research </span></div> <div>The researchers investigated the structure of the graphene aerogel at the <a href="/en/researchinfrastructure/CMAL/Pages/default.aspx">Chalmers Materials Analysis Laboratory (CMAL)​</a>.

The challenge is to reduce costs and improve the performance of wave energy systems. In that case, the Chalmers researcher Shun-Han Yang has helped the industry to boost their positions.</b></p><div>​<img src="/SiteCollectionImages/Institutioner/M2/Nyheter/shunhanyang.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Shun-Han Yang is a researcher at the Department of Mechanics and Maritime Sciences at the Division of Marine Technology. She has developed a numerical analysis procedure that can be used for assessing the long-term structural service life of the components used in wave energy systems. </div> <div><br /></div> <div> </div> <div>“The procedure allows the industry to assess the damage the waves impose mooring devices and power cables, etc., while calculating the wave power system’s power performance and energy cost” says Shun-Han Yang. </div> <div> </div> <div><br /></div> <div> </div> <div>The developed methodology has supported the industry and taken them from a stage of concept design validation to a full-scale prototype testing at sea. In technical terms from at TRL-level* of 3-4 to a TRL-level of 6-7. By using the numerical method, the potential structural failure or operation obstacles are identified, which would otherwise be devastating if the situation was encountered in reality. </div> <div> </div> <div><br /></div> <div> </div> <div>Jonas Kamf is CEO of Waves4Power, one of the industrial partners that Chalmers cooperates with. He explains that Waves4Power is a company under development with limited resources and therefore a strong partner network becomes a key resource. He sees Chalmers as an extra important partner for their business. </div> <div> </div> <div><br /></div> <div> </div> <div>“It's a lot of idea development but also verification of results from our test activities. Real results are set against theoretical calculations and in this way, we can link theory and reality in order to get even closer to reality in our forward-looking work” says Jonas Kamf. </div> <div> </div> <div><br /></div> <div> </div> <div>The collaboration with Chalmers in various fields also opens up for Waves4Power to be able to apply for extra financial support for technical development that would otherwise have been difficult to take part in. The connection between academia and industry is very important for this part of their development financing, he says, but perhaps even more importantly he sees Chalmers as a partner who can make them more realistic. </div> <div> </div> <div><br /></div> <div> </div> <div>“As a research resource, Chalmers is trustworthy and gives us as a collaborative partner an honest image, not a glorified picture of our reality. It’s easy to become blind in a development company and just see advantages. In this way, Chalmers is good at taking us down to earth and show us the reality as it is. It has laid a good foundation for good work in research and development.” </div> <div> </div> <div><br /></div> <div> </div> <div>For Chalmers, collaboration is a prerequisite for research. Shun-Han Yang believes that the close cooperation between academia and industry is what made her research possible. </div> <div> </div> <div><br /></div> <div> </div> <div>“To ensure the practicality of the numerical method, constant feedback given by the industry which highlights that challenges are necessary” says Shun-Han Yang. </div> <div> </div> <div><br /></div> <div> </div> <div>Waves4Power expects that within the next two years they will be fully commercial with a couple of installed wave power parks based on their latest technology, but it will continue to be a technology in development and Chalmers is a key resource.</div> <div> </div> <div><br /></div> <div> </div> <div><em>*TRL, Technology readiness levels are a method of estimating technology maturity of critical technology elements of a program during the acquisition process.
