That’s been the challenge for fifth graders all around the west part of Sweden to figure out, in order to get ready for Rädda ägget (Save the Egg). This year´s competition had close to 2,500 students attending, which is a new record.</b></p><p>There were a lot of excited students present when Chalmers organised the annual technology contest Rädda ägget between 8 and 9 November 2018. During the autumn, classes in the fifth grade around the west part of Sweden built devices with the aim of getting a raw egg to fall from a height of 15 meters without it breaking. The students had been creative with their designs, using items such as stuffed toys, paper boxes, balloons, parachutes and more to try to cushion the fall. Maria Nielsen, a teacher at Brandströmska skolan, says that her class has really fought to build their construction.</p> <p><br />“The students had to think really hard about what material to use and what type of construction they should make to protect the egg. They thought it was a fun assignment, they’ve really fought to get it right and even stayed between classes, which has also made it a good exercise in collaboration.”</p> <p><br />At the same time as Rädda ägget, the exhibition Upplev teknik was held. Here, the students could test different experiments together with students at Chalmers. The fifth graders learned how movement can become electricity by trying to turn on different lights using a stationary bike, they got to see what happens to the voice when you’ve inhaled helium, and they also got to eat ice cream made from custard sauce and liquid nitrogen. Anki Bengtsson, teacher at Fotö skola, says that her students were very happy with the day.</p> <p><br />“All the students have been really interested and curious, both when they tried different experiments and when they tested their egg constructions. It´s a good way to get the students interested in technology and maybe they’ll choose Chalmers in the future.”</p> <p><br />The Rädda Ägget competition consists of three categories; The technically smartest solution, the funniest design, and the best presentation. The award ceremony for the winning teams in the three categories takes place at Chalmers in December, where the students will be invited to accept their prizes. </p> <p><br /></p> <p><strong>Text:</strong> Sophia Kristensson<br /><br /></p>Fri, 09 Nov 2018 12:00:00 +0100 intelligence and quantum biology at the AHA Festival<p><b>​Creative technology, cave art, game intelligence, historical geniuses and investigating workshops. The AHA festival at Chalmers gathers researchers, students and artists - and invites the public to investigate the borders between science and art.</b></p><div>​This year, the theme is Play Everything and the festival will take place at the Student Union building at Chalmers on 19-21 November. The programme will be filled with public performances, lectures, workshops, exhibitions and seminar conversations. Permeating the festival is the driving force of curiosity and the festival aims to celebrate science as well as art.</div> <div><br /></div> <div> </div> <div>“It is essential to have different perspectives and competences when facing the challenges in our society. The AHA festival combines different disciplines within both science and art and offers new ways of exploring the world, aiming towards a sustainable society”, says Michael Eriksson, one of two project leaders of the AHA festival. <br /></div> <div> </div> <div><br /></div> <div> </div> <div>The idea of a border-crossing and international event emerged from a poetry evening at Chalmers. With inspiration from the ongoing artistic activities at the Department of Architecture,  the first AHA festival was arranged in 2014. This year’s festival, which is the fifth, involves several of the departments at Chalmers and presents a wide range of Chalmers research and thrilling border-crossing activities. <br /></div> <div><br /></div> <div> </div> <div>“It might not be that well known, but Chalmers rests upon both a scientific and an artistic ground.

The tool is today frequently used in education and research worldwide and the usage is steadily increasing – now with over 380,000 measurements performed.</b></p><div>​<img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/RF-WebLab_map.gif" alt="Map showing distribution of WebLab users" class="chalmersPosition-FloatRight" style="margin:5px" />RF WebLab give users worldwide the possibility to perform real high frequency measurements without having to purchase or manage complicated high frequency instruments such as signal generator, oscilloscope and amplifiers. Instead, the user submits their signal data on-line to Chalmers WebLab, where the actual measurements take place and the distorted signal result is sent back to the user. </div> <br /><div>The tool was setup for a student competition at the International Microwave Symposium conference – the world's largest microwave technology research conference, where students compete for developing algorithms to optimise signal quality and efficiency for a radio amplifier. </div> <br /><div>The online tool is linked to measurement equipment hosted by the Microwave Electronics Laboratory at Chalmers.

Other uses are to measure and optimise signal quality for modern radar signals, or for medical applications where radio signals are used to map human tissue for disease analysis. </div> <br /><div>The first version of the online tool was proposed by Thomas Eriksson and Christian Fager at Chalmers, and later Per Landin and Sebastian Gustafsson developed the concept. In 2014, National Instruments donated new hardware to RF WebLab, and Koen Buisman set up and further developed the new system, including a generic server client infrastructure, together with Bill Tokmakis. Further expansion to other types of measurement sets is planned. </div> <br /><div>&quot;The uniqueness of WebLab is the simplicity – anyone with a computer can connect to high-tech measuring equipment and perform measurements on a world-class system. And it's completely free of charge&quot;, says Thomas Eriksson. </div> <br /><div><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/People/KoenBuisman_170px.jpg" alt="Koen Buisman" class="chalmersPosition-FloatRight" style="margin:5px" />The current system has been in operation for three years, and over 380,000 measurements have been performed by users from around the world, both for education and research. At Chalmers, the system is actively used in both education and research. For the students, it becomes a unique opportunity to come closer to a real system, and the researchers appreciate the simplicity of measuring. </div> <br />&quot;We have had approximately 2000 unique users from academia and industry, from around the world.

At the institute, basic research will be transformed into practical use, in solutions or products that combat disease, improve health or conserve natural resources. BII also works as an incubator for start-up companies within the biotech area.<br /><br />&quot;It was simply not possible to miss out on this opportunity! The idea to build a completely new institute with focus on the translation of research and on innovation, as well as supporting spin-out of new biotech companies, is very exciting&quot;, says Jens Nielsen.<br /><br />Throughout his career, he has aimed to bridge top-level basic science with translation and innovation, and he has also started several companies.<br />&quot;BII is fully in line with my skills and interests, so having the opportunity to harvest on all that I have learned over the years will be fantastic.&quot;<br /><br />Even though the new positions means moving back to Denmark, Nielsen is optimistic when it comes to the consequences for Chalmers:<br />&quot;This will give new opportunities to BIO and thus to Chalmers. BII does not have basic research, and will therefore rely on solid collaborations with universities. In my new role as CEO I intend to establish close interactions with Scandinavian universities that have a strong position in life sciences, to further strengthen the innovation and competitive environment in Scandinavia.&quot;<br /><br />Jens Nielsen will keep his research group at the Division of Systems and Synthetic Biology at Chalmers.<br /><br />&quot;Yes, I will maintain my Chalmers affiliation with 100 percent focus on running the research group, that is, continue my supervision of my many PhD students and post docs.&quot;<br /><br /><br />Text: Mia Malmstedt<br />Photo: Novo Nordisk Foundation<br />Wed, 31 Oct 2018 16:00:00 +0100 nutrients from seafood process water<p><b>Process waters from the seafood industry contain valuable nutrients, that could be used in food or aquaculture feed. But the process waters are treated as waste. Researchers now show the potential of recycling these nutrients back into the food chain.</b></p>​During preparation of herring, shrimps and mussels, large amounts of process water are continuously pumped out as waste by the seafood industry. The water is used when boiling shrimps or mussels, or when filleting, salting and marinating herring, for example. Approximately 7000-8000 liters of water is used to prepare a ton of marinated herring. A stunning 50,000 liters of water is needed per ton of peeled shrimps, or per three tons of raw shrimp.<br /><br />But these side stream waters contain proteins, peptides, fats and micronutrients, which could be recycled and used, for example by the food industry, as an ingredient in feed or for growing microalgae. In fact, the leftover boiled water from shrimp preparation is basically a ready-made stock.<br /><br /><strong>Nutrients could be recycled</strong><br />The Nordic project NoVAqua, coordinated by Professor Ingrid Undeland of the Department of Biology and Biological Engineering at Chalmers University of Technology, has now shown the potential of extracting these important nutrients from the process waters.<br /><br />”It’s very important to help the industry understand that the side streams don’t need to be wasted. Instead, they should be treated as really exciting raw material,” she says.<br /><br />“The backbone of our project is a circular approach. In the past, we had a more holistic view on handling of food raw materials, but today so much is lost in side streams. Furthermore, we are in the middle of a protein shift, and there’s a huge demand in society for alternative protein sources.”<br /><br />The research project started in 2015 with the aim to recover nutrients from seafood process waters and create innovative uses for them. A similar approach is already successfully implemented in the dairy industry, where the residual liquid from cheese making – whey – is used in sports nutrition, as well as in different food and feed products.<br /><br /><strong>Much of the protein in lost</strong><br />When the research team measured the composition of process waters, they found them to contain up to 7 percent protein and 2,5 percent fat. In process waters from shrimp, astaxanthin, a red pigment and antioxidant often used as a dietary supplement, was also present.<br /><br />”Our calculations show that in a primary processing plant for herring, as much as 15 percent of the herring protein coming in to the industry leached out into the water and was treated as waste, thereby lost,” Ingrid Undeland explains.<br /><br />Using a two-step process, the research team managed to recover up to 98 percent of the protein and 99 percent of the omega 3-rich fats. The process resulted in a semi-solid biomass and a nutrient-rich liquid. After dehydration, biomass from shrimp boiling water was shown to contain 66 percent protein and 25 percent fat. Two tests were made, together with the University of Gothenburg and Skretting ARC, using this new biomass as an ingredient in feed for salmon, and the results were encouraging.<br /><br />The nutritious liquid was used for glazing frozen fish, thereby protecting it from going rancid. It turned out to be slightly more protective than water, which is currently used for such glazing. The fluid was also tested as a substance for microalgae-cultivation and was shown to enhance the growth of two types of algae. The algae biomasses can subsequently be used as sources of protein or pigment.<br /><br /><strong>A need for investments</strong><br />All in all, the research project pointed out several different ways to recycle the nutrients which are currently lost in the process waters. The next step is implementation in the seafood industry.<br /><br />“A major challenges is to get the industry to manage the water side streams as food, beyond the stage when they are separated from the seafood product. Today, that is the point where the side streams start being handled as waste. This means there’s a need for new routines for cooling and hygiene,” says Ingrid Undeland.<br /><br />In Sweden, the waste waters are purified to some extent before they go out of the factories. This means that many seafood producers already have the flotation technology needed in the second step of side stream recycling. But there are also investments to be made, says Bita Forghani Targhi, a post-doctoral researcher at the division of Food and Nutrition Science and colleague to Undeland.<br /><br />“The main challenge would be cost-related issues,” she says.<br /><br /><strong>The start of a new project</strong><br />The work now continues within the new project AquaStream, funded by the European Maritime and Fisheries Fund. Bita Forghani Targhi points out that an important next step will include consulting with local businesses, interviewing them on generated side streams and verifying the current nutrient loss through a primary characterisation of process waters. She has a positive outlook on the future:<br /><br />“I am quite positive on the fact that related industries, sooner or later, will be implementing these techniques. With ever increasing awareness on the value of recycling nutrients, this facilitates industrial processes to adopt feasible approaches towards a circular economy.”<br /><br /><br /><strong>FACTS ABOUT THE NOVAQUA PROJECT:</strong><br />The projects full name is Extracting Novel Values from Aqueous Seafood Side Streams, or NoVAqua for short. The project was started in 2015 and closed in 2018, and was funded by Nordic Innovation. Partners involved alongside Chalmers included Räkor &amp; Laxgrossisten AB, Fisk Idag AB, SWEMARC at the University of Gothenburg, DTU Foods, Bio-Aqua and Skretting ARC. Research on algae cultivation was done in collaboration with the researchers Eva Albers and Joshua Mayers at Industrial Biotechnology at Chalmers. Scandic Pelagic AB and Klädesholmen Seafood AB were also affiliated to the project, and play an important role in the new AquaStream project.<br /><br /><br />Text: Mia Malmstedt<br />Photo: Johan Bodell, and private<br />Wed, 31 Oct 2018 09:00:00 +0100 forces for a European quantum computer<p><b>​Ten international partners from academia and industry will collaborate in a unique research endeavour to build a high-performance quantum computer, available to a broad community of users.

Following media reports of tyre manufacturer Nokian Tyres questioning the study’s findings, the researchers at Chalmers are now issuing a statement in reply. They reject all claims of errors.</b></p><div>Anna Furberg, Sverker Molander and Rickard Arvidsson write:<br /><br />“We have studied positive and negative impact on human health <a href="/en/departments/tme/news/Pages/Studded-winter-tyres-cost-more-lives-than-they-save.aspx">linked to the use of studded tyres from a life cycle perspective</a>. The results clearly show that the negative impact outweighs the positive.&quot;</div> <div><br /></div> <div><h5 class="chalmersElement-H5">Use in Scandinavia</h5> <div>The negative impact is dominated by worn particles emitted to air during the use of studded tyres here in Scandinavia (67–77 percent).</div> <div> </div> <div>Nokian Tyres criticises our study and claims the following, according to, among others, the magazine Teknikens värld, which we quote below in italics:</div> <div> </div> <div>“Due to wear, studded winter tyres emit large particles that have a diameter of at least 10 micrometres (PM10). It is problematic that the study is based on the assumption that people are constantly exposed to PM10 particles.”</div> <div> </div> <div>In its reply, the company does not acknowledge that through wear studded tyres also emit smaller particles that adversely affect health. According to Ferm and Sjöberg (2015), the use of studded tyres gives rise to 20–50 mg of airborne particles that are 2.5–10 micrometres in size (PM2.5–PM10) per vehicle-kilometre. It is these particles, ranging in size from PM2.5 to PM10, that we have included in our calculations – they are linked to various health problems such as heart and lung diseases. Additionally, we have only included particles from wear during the winter half of the year when studded tyres are actually used. Everyone is not always exposed to this wear, which is why an average absorption of particles (up to 10 micrometres) for the European population (Goedkoop et al., 2013) was used in the study.</div> <div> </div> <div>“Even those who drive vehicles with non-studded winter tyres benefit from studded tyres which make the road surface rougher, giving non-studded tyres better grip.”</div> <div> </div> <div>This effect has been taken into account in the statistics that we use regarding the reduced number of accidents through the use of studded tyres instead of non-studded tyres (Elvik, 1999).</div> <div> </div> <div>“A ban on using studded tyres would not improve the environment or public health, conversely the situation would worsen because decreased use of studded tyres would increase the need for sanding, which is a major source of particles.”</div> <div> </div> <div>Our study shows that public health is adversely affected through the use of studded tyres. According to our knowledge, there is also no direct link between reduced use of studded tyres and increased sanding. We see several additional potential alternatives to studded tyres, such as electronic anti-skid systems and durable asphalt. But all these need to be studied further from a life cycle perspective in order to investigate both advantages and disadvantages and to enable a statement to be made about their potential as alternatives to studded tyres. At present, we cannot assess the health effect of the alternatives. The statement above has therefore not been proved.</div> <div> </div> <div>“In the debate on winter tyres it is important to highlight both road safety and environmental aspects without being biased towards either studded or non-studded tyres.”</div> <div> </div> <div>We agree. In this study we have concentrated on the impact of studded tyres on human health. Both negative and positive. Here, we have approached the issue neutrally and evaluated all differences between studded and non-studded tyres that we have been able to identify as relevant in the context.</div> <div> </div> <div>The result from our calculations shows that particle wear on roads from the use of studded tyres contributes substantially to negative impact on people’s health, and exceeds the positive effect in Scandinavia in the form of saved lives. We are working within a relatively large range, where cautious figures must be compared to each other, and high estimates in a corresponding way.</div> <div> </div> <div><strong>For Sweden this means – if we make a high estimate – 770 life years saved, thanks to the studs, and about twice as many life years lost due to particle wear alone. If we make a low estimate – 60 life years saved in Sweden – the negative health effects of particle wear may be about seven times higher than the positive effects.</strong></div> <div> </div> <h5 class="chalmersElement-H5">Production of studs </h5> <div>According to our study, the production phase causes 23–33 percent of the negative impact on health, nearly all of which is outside Scandinavia.</div> <div> </div> <div>“The studs contain extremely small quantities of cobalt, and only on the cemented carbide stud pins to strengthen them. The cemented carbide pins on a studded tyre contain in total about 5 grams of cobalt.”</div> <div> </div> <div>In our calculations we have assumed that a studded tyre contains a maximum of 5 grams of cobalt.</div> <div> </div> <div>“The tyre industry uses nearly exclusively, up to 95 percent, recycled cemented carbide.”</div> <div> </div> <div>Recycled cemented carbide has also had an impact on people’s health in the mining sector. In our calculations we have used a degree of recycling comprising 10–14 percent of cemented carbide, based on the average global recycling for tungsten, which is the main component of cemented carbide (Graedel et al., 2011; Leal-Ayala et al., 2015). If the tyre industry has a higher degree of recycling, this is good news. We welcome information from Nokian Tyres which could in that case support this statement.</div> <div> </div> <div>“Cobalt does not only exist in the Democratic Republic of the Congo (the DRC), mining also takes place in Finland, for example.”</div> <div> </div> <div>Global production of cobalt is dominated by the DRC, accounting for 50 percent (USGS, 2017), which is why in our calculations we presuppose that all mined cobalt comes from there. If we instead assume that 50 percent of mined cobalt comes from the DRC – and in an extremely simplified way assume that the rest is produced in countries where safety and health data from the mining industry can be represented by such data in the USA – the total negative health impact linked to the use of studded tyres decreases by 4–10 percent. We know that this is a certain underestimate of the health impact.</div> <div> </div> <div><strong>We are therefore sure of our conclusion that studded tyres, generally, also take lives in areas that do not have wintry weather, and that this accounts for roughly a third of the negative impact on health. A manufacturer claiming otherwise should trace their own resource flows and show that they deviate from those prevalent in the market.</strong></div> <div> </div> <h5 class="chalmersElement-H5">Cobalt in general</h5> <div>To conclude, several actors have reacted to the fact that the use of cobalt in studded tyres is small in relation to other uses, such as in electronics and vehicle batteries.</div> <div> </div> <div>Yes, this is of course true. But in this particular study we are focusing on the health effects of studded tyres. The problems of cobalt – and the human suffering connected to the mining – are also significant in this comparison. This is what we are saying.</div> <div> </div> <div>It does not mean that we are making light of the serious problems caused by cobalt overall. On the contrary. </div> <div> </div> <div>Chalmers recently organised the world’s first conference on the subject of battery recycling. In conjunction with this, battery researcher Martina Petranikova highlighted in the media the need to recycle cobalt and other materials. In March a colleague demonstrated the possibility of recycling cobalt and other materials from motor vehicles to achieve a less wasteful material turnover in society. In an earlier study our group also looked at alternatives to replace cobalt with materials based on the more common element carbon (Arvidsson and Sandén, 2017).</div> <div> </div> <div>We must also understand that many major areas of application contain great potential for utilising cobalt material again and again. However, not in studded tyres (Furberg et al., 2019). In the wear of the studs, most of the cemented carbide is emitted into the environment and is lost from the cycle that we humans can use – in principle, dispersed forever.</div> <div> </div> <div><strong><em>Anna Furberg, Sverker Molander and Rickard Arvidsson</em></strong></div></div> <div><br /></div> <div><h4 class="chalmersElement-H4">References</h4> <div> </div> <ul><li>Arvidsson, R., Sandén, B.A., 2017.

In order to succeed, carbon dioxide capture has to scale up. Chalmers has the technology, but who dares take the first step to commercialize?</b></p>​<span style="background-color:initial">In the UN climate panel, the IPCC report describes how we not only need to reduce the rate of emissions but, in the long run, also reduce the amount of carbon dioxide in our atmosphere. This means that we need to capture carbon dioxide. Chalmers conducts research in the field and has reached far. One of the researchers in the field is Henrik Leion, Associate Professor at Chalmers Department of Chemistry and Chemical Engineering.</span><div><br /></div> <div>&quot;We must start catching all carbon dioxide, regardless of fuel. Right now we are working with biofuels. The fossil fuels already work well to capture. The technology for this is available. What prevents us is primarily economy and legislations.<img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/Koldioxidinfångning/Henrik%20Leionweb.png" class="chalmersPosition-FloatRight" alt="Photo of Henrik Leion" style="margin:5px" /><br /><br /></div> <div>The technique Henrik Leion researches and develops is based on oxygen-bearing solids that replace combustion of oxygen as a gas. His research is part of several projects around a technology called CLC, which stands for chemical looping combustion. In most cases, the heat is generated in power plants through combustion in air. This forms carbon dioxide mixed with another type of gas, depending on technology, and gases are difficult to separate from each other. In order to get as clean a stream of carbon dioxide as possible, CLC uses a solid material where oxygen is included as an oxide, for example ordinary rust. Instead, water and carbon dioxide are created, which are easier to distinguish from each other. When the oxygen on the oxygen carrier is consumed, it is exposed to air and the material is then reoxidized and reusable.</div> <div><br /></div> <div>Research at Chalmers within CLC is conducted jointly by several research groups across institutional boundaries. Henrik Leion looks at how oxygen carrier and fuel can be optimized.</div> <div>As the situation is now, it is not enough to capture only carbon dioxide from fossil sources. Also carbon dioxide from bio combustion must be collected in order to achieve negative net emissions.</div> <div><br /></div> <div>&quot;We will need to capture carbon dioxide to a very large extent. Emissions must begin to sink within just a few years, and if we do not do that now, it means that around 2050, we will have to catch more carbon dioxide than we release to compensate for what we did not do 30 years earlier, he says. <img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/Koldioxidinfångning/Järnoxidweb.png" class="chalmersPosition-FloatRight" alt="Iron oxide being poured into a bowl" style="margin:5px" /><br /><br /></div> <div><span style="background-color:initial">CLC is primarily a technology that can work at stationary facilities. Capture involves heavy loads. Not only does the oxygen carrier consist of some kind of metal. The carbon dioxide collected weighs about three times more than the fuel, which in itself would mean increased emissions for a vehicle due to the weight.</span><br /></div> <div><br /></div> <div><strong>Economy and legislation impede</strong></div> <div>Thus, CLC could be of great use if it was used at commercial level. But yet nobody dares to take the financial risk to invest in the technology. So far, it has been tested in the Chalmers test facility of 12 megawatts with successful results. But a major effort is required for technology to come through, believes Henrik Leion.</div> <div><br /></div> <div>“Someone must dare to test the technology in a 50 megawatt facility. This will probably mean losing money initially, but the technology needs this to be further developed, he believes.”</div> <div><br /></div> <div>In addition, it must be cheaper to use the technology. The price must be able to compete with carbon credits. Today, a carbon credit, ie the right to release a ton of carbon dioxide, costs about 20 euros. CLC is slightly more expensive, but could, with a bigger initiative, become cheaper. If it is cheaper to collect carbon dioxide than to release it into the atmosphere, chances are that the industry will invest in the technology. In addition, CLC requires that large parts of the combustion system is rebuilt. Another problem is the storage.</div> <div><br /></div> <div>&quot;There is no logistics and legislation to deposit carbon dioxide. It takes about 10,000 years for the gas to be converted into limestone. Carbon dioxide is not very dangerous, it is not comparable to nuclear waste, but we talk about huge amounts here, says Henrik Leion.</div> <div><br /></div> <div>A legislative problem is the question of liability. Who will be responsible for the storage for 10,000 years? It has also proved difficult to find places where governments and populations accept storage. Another way to store the greenhouse gas is to pump it into drained oil sources at sea. It is expensive and lacks logistics, but it may be necessary.</div> <div><br /></div> <div><strong>Must be put into use</strong></div> <div>Any type of capture technique must be taken into use. Without capture techniques, climate targets will not be reached. What is needed, Henrik says, is that a major energy company dares to test the technology at the commercial level. That company must be ready to lose money. Somewhere, money will probably be lost, but it may be something we have to accept to avoid a significantly higher temperature rise. Without capture, we do not have a chance to stop the temperature rise at 2 degrees, Henrik says who soon will be off for parental leave.</div> <div><br /></div> <div>&quot;To be honest, it is frankly not morally easy for me to take a break from the research in this situation. My way of handling my climate depression is to work”, he says. </div> <div><br /></div> <div>Text and photo: Mats Tiborn</div> <div><br /></div>Fri, 19 Oct 2018 00:00:00 +0200 equality a powerful tool for higher quality<p><b>​Thanks to dedicated work on gender equality, his department went from 0 to 40 per cent female faculty in 20 years. Now, Paul Walton, Professor in Chemistry at York University, offers his advice on Chalmers’ big investment in gender equality.</b></p>​<span style="background-color:initial"> “I’ve visited more than 200 hundred universities and departments all over the world to talk about gender equality. But Chalmers is different,” says Paul Walton. </span><div><span style="background-color:initial">He is referring to Chalmers ten-year investment program, the Gender Initiative for Excellence, or Genie. With a budget of 300 million kronor, the aim of the investment is to increase the proportion of female professors at Chalmers from today’s figure of 17 per cent, to 40 per cent. </span><br /></div> <div><span style="background-color:initial">“This is by far the biggest single investment in gender equality that any university has made. Chalmers has a big problem with gender equality, but has now understood that in a very clear way. There’s a real determination to tackle it. It was obvious from the faces in the audience today that there’s real commitment here,” says Paul Walton, referring to the lecture he earlier delivered for Chalmers staff and management in Palmstedtsalen. </span><br /></div> <div><br /></div> <div><strong>Equality and quality go hand in hand</strong></div> <div><span style="background-color:initial">When Paul Walton started working with gender equality in academia 25 years ago, the primary motivation was to make it equal and fair. But several years on, research has shown that a better gender balance leads to greater scientific success, and increased quality is now one of the main motivations. In fact, he believes that equality measures are one of the most powerful tools a university can use to improve itself.  </span><br /></div> <div><span style="background-color:initial">“We know that we, and probably all universities, have internal structures and cultures which favour men’s career development over women’s. Even if it’s only small differences, it ends up affecting a lot of people over a long time, which leads to big effects. We need to make better use of the competence of the entire population, to take the next step in quality,” says Chalmers President Stefan Bengtsson.</span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">So how do you achieve gender equality? According to Paul Walton, it’s important to share data broadly and openly, for example, data concerning pay and qualifications in promotions, and to incorporate gender aspects into all statistics. Leadership is also key, in particular at the departments. </span><br /></div> <div><span style="background-color:initial">“It is mainly at the department where the cultural changes can occur, and where the Head of Department has an important role. Everyone will follow your example as Head of Department,” he says. </span><br /></div> <div><br /></div> <div><strong>Hug a social scientist</strong></div> <div><span style="background-color:initial">You also need to embrace and learn from research from the social sciences, concerning factors behind inequality between the sexes. For example, everyone – women as well as men – is guilty of unconscious biases. Tests show that people generally rate a CV with a male name higher than an identical CV with a female name, as an example. </span><br /></div> <div><span style="background-color:initial">In the UK, it has become common to try and rectify this problem by training people to become aware of their own unconscious biases and correct them themselves.</span><br /></div> <div><span style="background-color:initial"> “Unfortunately, this doesn’t work. The only way we’ve found to correct for bias is that in committees looking at employment, promotion, pay and so on, you need dedicated observers with the single task of monitoring other members for unconscious bias. For example, the observer can time how long they give to discussing each candidate and count the number of negative and positive comments,” says Paul Walton.  </span><br /></div> <div><br /></div> <div><strong>A globally unique investment</strong></div> <div>Paul Walton thinks that Chalmers, with this big investment, has the possibility to try new and interesting methods for combating inequality. This could include positions reserved for women, and new ways of recognising academic success. </div> <div><span style="background-color:initial">“The world will be watching on this one! This is the biggest gender-equality investment that I have heard of in academia.” </span><br /></div> <div><br /></div> <div><strong>Things could get uncomfortable</strong></div> <div>One challenge will be the backlash, which, according to Paul Walton, is an accompaniment to anything which seems to give an advantage to women. You need to be ready for things to get uncomfortable – that’s something which Thomas Nilsson, Head of the Physics Department took from Walton’s lecture. He likens the road to becoming a professor to an obstacle course. </div> <div><span style="background-color:initial"> “The way up is determined by those who are already in the </span><span style="background-color:initial">system, which means that the system repeats itself.

This opens up new opportunities for structural batteries, where the carbon fibre becomes part of the energy system. The use of this type of multifunctional material can contribute to a significant weight-reduction in the aircraft and vehicles of the future – a key challenge for electrification.</b></p><p>Passenger aircraft need to be much lighter than they are today in order to be powered by electricity. A reduction in weight is also very important for vehicles in order to extend the driving distance per battery charge.</p> <p>Leif Asp, Professor of Material and Computational Mechanics at Chalmers University of Technology, conducts research into the ability of carbon fibres to perform more tasks than simply to act as a reinforcing material. They can store energy, for example.</p> <p>“A car body would then be not simply a load-bearing element, but also act as a battery,” he says. “It will also be possible to use the carbon fibre for other purposes such as harvesting kinetic energy, for sensors or for conductors of both energy and data. If all these functions were part of a car or aircraft body, this could reduce the weight by up to 50 percent.” </p> <p>Asp headed up a multidisciplinary group of researchers who recently published a study on how the microstructure of carbon fibres affects their electrochemical properties – that is, their ability to operate as electrodes in a lithium-ion battery. So far this has been an unexplored research field.</p> <p><img alt="Leif Asp carbon fibre" src="/SiteCollectionImages/Institutioner/IMS/MoB/Leif%20Asp%20kolfiber%20webb.jpg" style="margin:10px 5px" /><br /><em>Leif Asp with a bobbin of carbon fibre yarn. The electrodes in a structural lithium ion battery consist of carbon fibre yarn arranged in a grid in a polymer (see illustration). Every length of yarn consists of 24,000 individual carbon fibres.</em> <br /><br /></p> <p>The researchers studied the microstructure of different types of commercially available carbon fibres. They discovered that carbon fibres with small and poorly oriented crystals have good electrochemical properties but a lower stiffness in relative terms. If you compare this with carbon fibres that have large, highly oriented crystals, they have greater stiffness, but the electrochemical properties are too low for use in structural batteries.</p> <p><br /><img class="chalmersPosition-FloatLeft" src="/SiteCollectionImages/Institutioner/IMS/MoB/Kolfiberrulle_webb.jpg" width="298" height="447" alt="" style="margin:5px 10px" />We now know how multifunctional carbon fibres should be manufactured to attain a high energy storage capacity, while also ensuring sufficient stiffness,” Asp says. “A slight reduction in stiffness is not a problem for many applications such as cars. The market is currently dominated by expensive carbon fibre composites whose stiffness is tailored to aircraft use. There is therefore some potential here for carbon fibre manufacturers to extend their utilisation.”</p> <p>In the study the types of carbon fibre with good electrochemical properties had a slightly higher stiffness than steel, whereas the types whose electrochemical properties were poor are just over twice as rigid as steel.</p> <p>The researchers are collaborating with both the automotive and aviation industries. Leif Asp explains that for the aviation industry, it may be necessary to increase the thickness of carbon fibre composites, to compensate for the reduced stiffness of structural batteries. This would, in turn, also increase their energy storage capacity.</p> <p><br /> </p> <p><br />“The key is to optimise vehicles at system level – based on the weight, strength, stiffness and electrochemical properties. That is something of a new way of thinking for the automotive sector, which is more used to optimising individual components. Structural batteries may perhaps not become as efficient as traditional batteries, but since they have a structural load-bearing capability, very large gains can be made at system level.”</p> <p></p> <div> </div> <div>He continues, “In addition, the lower energy density of structural batteries would make them safer than standard batteries, especially as they would also not contain any volatile substances.”</div> <div><br /> </div> <div> </div> <h3 class="chalmersElement-H3">Read the article </h3> <p></p> <p></p> <div><a href="">Graphitic microstructure and performance of carbon fibre Li-ion structural battery electrodes</a> in the journal Multifunctional Materials.</div> <div> </div> <h3 class="chalmersElement-H3">For more information, contact:</h3> <div>Leif Asp, Professor of Material and Computational Mechanics, Chalmers, +46 31 772 15, <a href=""><br /></a></div> <div><br /> </div> <div><em>Text: Johanna Wilde &amp; Marcus Folino</em></div> <div><em>Photo: Johan Bodell</em><br /></div> <p></p>Thu, 18 Oct 2018 07:00:00 +0200,-IMS.aspx,-IMS.aspxInternational award to Johan Malmqvist, IMS<p><b>Four questions to Johan Malmqvist, professor at the Department of Industrial and Materials Science, who recently received the Leonardo da Vinci Medal, awarded by the European Society for Engineering Education (SEFI).</b></p><strong> </strong><span style="background-color:initial"><strong>Congratulations Johan, this is a very honourable award, you must be proud?</strong></span><div> </div> <div>&quot;Yes, the Leonardo da Vinci medal is the highest award of SEFI. It is awarded once a year to a now living person who has contributed significantly to the development of engineering education at university level and made a difference internationally. So, of course, I am very proud!&quot;</div> <div> </div> <div><strong>Did you get the medal for your efforts for the development of engineering education in general and your work in CDIO?</strong></div> <div> </div> <div>&quot;My background is in design research,  specifically methodology and IT support for product development. Thus, I am passionate about highlighting product development in engineering education. As part of this, I took part in starting the CDIO initiative, Conceive, Design, Implement, Operate (CDIO). CDIO is an international initiative aimed at developing a framework for the improvement and development of engineering education worldwide.&quot;</div> <div> </div> <div>&quot;Together with Ed Crawley (2000-2012) and Ron Hugo (2012-2017), I was one of two co-directors from the establishment of the CDIO Initiative from 2000 to 2017. During this period, the CDIO initiative grew from a project with universities as four founding partners to a global organization with over 140 cooperating institutions (see, for example, Malmqvist, Hugo &amp; Kjellberg, 2015). The annual international CDIO conference, which has run annually since 2005, usually attracts about 300 participants.&quot;</div> <div> </div> <div><strong>Tell us more about CDIO</strong></div> <div> </div> <div>&quot;CDIO stands for &quot;Conceive, Design, Implement, Operate&quot; and it is actually a description of the product lifecycle. From identifying the needs of a product, planning what is going to be developed, creating the design, testing, manufacturing, using, maintaining and eventually recycling or retiring the product. Most engineers have a specialised role in one part of that process. You work as a designer, a production planner, a programmer, etc. But to be a good engineer you must be able to work with people throughout the product lifecycle. Having the understanding that the decisions I take can have consequences for others and how to best help others is essential. A CDIO education takes place in close collaboration with companies and society with the aim of preparing the students for their future engineering role, where they will in future be able to act as a driving force for a sustainable development.&quot;</div> <div> </div> <div>&quot;We started the CDIO initiative together with three other universities: Chalmers University of Technology, KTH Royal Institute of Technology and Linköping University, and MIT, Massachusetts Institute of Technology in the United States. The starting point was that engineering education had become increasingly distant from practical engineering work. The vision for the CDIO initiative was to train students who combine a deep understanding of the technical fundamentals with the ability to be able to take a leading role in the design, implementation, operation and maintenance of new products and processes.&quot;</div> <div> </div> <div><strong>What is your focus in the future?</strong></div> <div> </div> <div>&quot;I have recently stepped down as a dean of education for Chalmers MATS (Mechanical Engineering, Mechatronics and Automation, Industrial Design, and Maritime Engineering) education area.
