At the centre of the earth, the pressure can reach hundreds of gigapascals – and such conditions are achievable in laboratory settings today. Examples of areas where pressure is used today include the synthesis of superconductors, materials which can conduct electric current without resistance.

But currently, they are often dependent on rare, or in some cases toxic, materials. They are also leading to a gradual build-up of great mountains of electronic waste. There is a real need for organic, renewable materials for use in electronic textiles,” says <a href="/en/staff/Pages/sozan.aspx">Sozan Darabi</a>, doctoral student at the Department of Chemistry and Chemical Engineering at Chalmers University of Technology and the Wallenberg Wood Science Center, and lead author of the scientific article which was recently published in ASC Applied Materials &amp; Interfaces. </div> <div>   </div> <div>Together with <a href="/en/staff/Pages/anja-lund.aspx">Anja Lund</a>, researcher in the same group, Sozan Darabi has been working with electrically conductive fibres for electronic textiles for several years. <a href="/en/departments/chem/news/Pages/Student-thesis-led-to-conductive-thread.aspx">The focus was previously on silk</a>, but now the discoveries have been taken further through the use of cellulose. </div> <div> </div> <h2 class="chalmersElement-H2">Built-in electronics in non-toxic, renewable, and natural materials</h2> <div>The results now presented by the researchers show how cellulose thread offers huge potential as a material for electronic textiles and can be used in many different ways.</div> <div>  </div> <div>Sewing the electrically  conductive cellulose threads into a fabric using a standard household sewing machine, the researchers have now succeeded in producing a thermoelectric textile that produces a small amount of electricity when it is heated on one side – for example, by a person's body heat. At a temperature difference of 37 degrees Celsius, the textile can generate around 0.2 microwatts of electricity.</div> <div>   </div> <div>“This cellulose thread could lead to garments with built-in electronic, smart functions, made from non-toxic, renewable and natural materials,” says Sozan Darabi.</div> <div>   </div> <div>The production process for the cellulose thread has been developed by co-authors from Aalto University in Finland. In a subsequent process, the Chalmers researchers made the thread conductive through dyeing it with an electrically conductive polymeric material. The researchers' measurements show that the dyeing process gives the cellulose thread a record-high conductivity – which can be increased even further through the addition of silver nanowires. In tests, the conductivity was maintained after several washes.</div> <div> </div> <h2 class="chalmersElement-H2">The benefits of e-textiles and cellulose</h2> <div>Electronic textiles could improve our lives in several ways.

The e-textile thread developed by the researchers measures a record-high conductivity for cellulose thread in relation to volume of 36 S/cm-, which can be increased to 181 S/cm by adding silver nanowires. The thread coated with PEDOT: PSS can handle at least five machine washes without losing its conductivity. By integrating the cellulose yarn into an electrochemical transistor, the researchers have also been able to demonstrate its electrochemical function.</div> <h2 class="chalmersElement-H2">More about: textiles from nature and fashion industry interest </h2> <div>Throughout human history, textiles have been made from natural fibre and cellulose. But since the middle of the 20th century, synthetic fibres have become more common in our clothing, particularly in the fashion industry. With the greater focus and awareness now on sustainable alternatives, interest in natural fibres and textiles is returning and growing.

The prize is considered as one of Sweden´s largest, for researchers.</b></p><span style="background-color:initial">&quot;To be awarded the Göran Gustafsson Prize means a lot to me. It shows that one has done something good, and it is nice to be noticed for that&quot;, says Kasper Moth-Poulsen in a press release from the Royal Swedish Academy of Sciences.</span><div>How we can store energy from the sun is one of our big problems for a sustainable future. Kasper Moth-Poulsen believes that he has found part of the solution. His group of researchers at Chalmers has, among other things, developed a specially designed molecule that can capture the energy from the sun's rays and emit it as heat much later. When the molecule is hit by the sunlight it changes shape into an energy-rich isomer that can be stored. By using the molecule in a window film, it may be possible to heat homes and have a comfortable indoor environment, throughout the day.<br /><br /></div> <div>With the help of the solar energy storage system, Most, which the research group has developed, it is possible to save energy for up to 18 years. But very recently, they have also started a new project to develop a material that can both store solar energy and absorb energy from the environment, as well as emit it as heat. Instead of liquids, they will now use solids. The material should be able to do several things at the same time, and the hope is that the two different systems will be able to be combined in the future.</div> <div>This year it is 30 years since the Göran Gustafsson Prize for Young Researchers in Sweden was awarded for the first time. In addition to Chalmers the 2021 prize winners are from Linköping University, Karolinska Institutet and KTH. They will each receive more than SEK 5 million.

In close collaborations researchers, industry and other actors, will develop new sustainable food systems in Sweden. This means an increase in production of more nutritious food, while the environmental impact decreases.</span></p> <h2 class="chalmersElement-H2">BLUE FOOD</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">BLUE FOOD, centre for the seafood of the future, will result in completely new Swedish seafood products that could play an important role in the ongoing protein shift. This shift means leaving red meat as the primary source of protein for more sustainable and healthy alternatives. Ingrid Undeland, Professor of Food Science at the Department of Biology and Biological Engineering, will, as the research coordinator, have a central role in BLUE FOOD.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“I hope that BLUE FOOD will contribute to more of our Swedish blue raw materials being processed nationally <span>−</span> and that this will positively influence new job opportunities, competence level, self-sufficiency and profitability in the Swedish fishing and seafood industry,” she says.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">One goal of the centre is that a larger proportion of the wild fish caught in Sweden will be used as food – another is to expand Swedish aquaculture, i.e. the cultivation of, for example, fish, mussels and algae. Today, as much as 85 percent of the wild Swedish-caught wild fish is not used for food, but for low-value products that are later used in animal feed. This includes both small fish species such as herring, and sprat, but also the parts of the fish that remain after the fillet is removed. These species and cutting details need to be better utilised. But technological development is required to succeed.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“My research group has extensive experience from processes that can be used to refine both residual raw materials and small fish species. For almost 20 years, we have used complex marine raw materials to isolate functional proteins, i.e. proteins that can provide structure to food at different levels. This knowledge will be used in the doctoral student project that Food and Nutrition Science at Chalmers will supervise in the centre. When it comes to seafood quality, we also have extensive experience, not least on how to avoid oxidation of the unsaturated marine fats, which otherwise leads to the food becoming rancid and losing nutritional value,” says Ingrid Undeland.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Mehdi Abdollahi and Ann-Sofie Sandberg from the Division of Food and Nutrition Science and Robin Teigland from the Department of Technology Management and Economics (TME) also participate, as artificial intelligence,  AI, and digitalisation in the blue sector are important focus areas in BLUE FOOD. The latter will also form the basis for a PhD-student project in a later stage of the centre.</p> <p class="chalmersElement-P"> </p> <h2 class="chalmersElement-H2">FINEST</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">FINEST is a centre for future innovations in a sustainable food system. The centre brings research on sustainability and nutrition, food technology, consumer behaviour, innovation management and system change together. In addition, there is a joint development of methods through the Food Transition Lab run by Rise, and a co-creation platform that will be created within the centre formation.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The centre wants to contribute to innovation in the Swedish food sector by involving actors from all parts of the value chain – to jointly create the best conditions for innovation, contribute to system change and support concrete projects, including berries as raw materials and experimental value chains.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Professor Maria Elmquist at TME, on Chalmers' involvement in FINEST:</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“I will lead a work package together with RISE where we will work with innovation management and study how established players can find new paths to innovation by collaborating in new ways and with new parties. We will recruit a doctoral student with a focus on innovation in the food sector, who will, among other things, work closely with ICA and the Rural Economy and Agricultural Societies (Hushållningssällskapet). The activities in the centre will constitute an exciting research arena and lab environment for us, as we will be able to collaborate and study the participating actors, and easily test new models and tools.”</p> <p class="chalmersElement-P"> </p> <h2 class="chalmersElement-H2">PAN SWEDEN</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Efforts to limit the environmental impact from animal-based food are needed to meet the goals of Agenda 2030 but innovations within plant-based proteins options are lagging. Evidence-based knowledge within food processing, consumption and health benefits of plant-based proteins is currently scarce, which limits the necessary further development.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The centre PAN SWEDEN (plant-based proteins for health and wellbeing) will in collaboration with universities, research institutes, the Swedish industry and public sector partners, develop new knowledge and new methods to examine how increased consumption of plant-based proteins affects health and well-being. PAN brings together a unique set of interdisciplinary competence and creates a new infrastructure that integrates research on food, nutrition, technology, medicine and social sciences. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Marie Alminger, Professor of Food and Nutrition Science, is part of PAN’s management team and she will participate in the research with focus on characterisation of plant-based proteins. Among other things, the researchers want to clarify the relationship between processing, structure, bioavailability, digestion of proteins, and how the proteins can affect the intestinal flora and health. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> “We will compare selected plant proteins (model proteins combined with fibre components) with animal foods, in this case chicken. We want to identify raw materials with promising properties that work well in food processes − but also gain knowledge about possibilities and health effects, or risks, that come with increased use of plant-based foods,” she says.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Anna Ström is Professor at the Department of Chemistry and Chemical Engineering. She is also part of the management of PAN and is responsible for the focus area &quot;Biomolecular signatures in a precision nutrition perspective&quot;. Here, the researchers will work mainly on how plant-based nutrition is absorbed by the body and investigate the processes for uptake of different vegetable proteins in the digestive systems. As a chemist, Anna Ström contributes with the physical chemical aspects and she is particularly interested in exploring one idea with an exciting focus:</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“The idea is to develop a sensor that makes it possible to follow how we degrade various plant-based proteins, which could enable us to look directly into the intestinal system. We see a great need for such technical solutions. With the help of AI, the information can be translated into new, important knowledge on the functions of different proteins in our digestive systems,” says Anna Ström.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Another research area to be explored is how the combination of different proteins, and high and low fibre levels in the diet affects us from a nutritional and health perspective.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><strong>Read the press release from Formas:</strong> <a href="https://formas.se/en/start-page/archive/news/news/2020-11-23-multi-million-investment-in-swedish-centres-for-food-research-and-innovation.html">Multi-million investment in Swedish centres for food research and innovation​</a></p> <p class="chalmersElement-P"> </p>Tue, 22 Dec 2020 08:00:00 +0100https://www.chalmers.se/en/departments/ace/news/Pages/Extracting-precious-zinc-from-waste-ash.aspxhttps://www.chalmers.se/en/departments/ace/news/Pages/Extracting-precious-zinc-from-waste-ash.aspxExtracting precious zinc from waste ash<p><b>​Incineration of solid waste produces millions of tonnes of waste fly ash in Europe each year, that most commonly ends up in landfill. But this ash often contains significant amounts of precious metals, such as zinc. A unique method developed by researchers at Chalmers can now help extract these precious metals, potentially leading to reductions in environmental pollution, landfill and transport.</b></p><div>​During waste incineration, the released flue gases are purified and the small particles present are separated, leading to the formation of fly ash. This fly ash contains toxic substances, such as dioxins, and so is normally classified as hazardous waste and landfilled. But it also contains valuable metals, such as zinc, which are thereby lost.  But a new method from Chalmers University of Technology, tested at pilot scale and detailed over several years of research, involves treating this waste with an acid wash, also separated from the flue gases, to separate the zinc from the fly ash. The zinc can then be extracted, washed and processed into raw material.  </div> <div> </div> <div>  – In our pilot study, we found that 70 percent of the zinc present in fly ash can be recycled. The zinc is not extracted as a pure metal, which would be a much more intensive process, but instead as a zinc-rich product, which can be sold to the metal industry and processed further in currently existing industry production lines,” says <a href="/en/Staff/Pages/karin-karlfeldt.aspx">Karin Karlfeldt Fedje</a>, Associate Professor at the Department of Architecture and Civil Engineering, and researcher at the recycling and waste management company Renova AB.  </div> <div> </div> <h2 class="chalmersElement-H2">Ash turned into useful material </h2> <div> </div> <div>In further refinement to the method, the researchers have been able to significantly reduce the level of toxicity.  </div> <div> </div> <div>  – After extraction, we incinerate the residual ash again to break down the dioxins. Ninety percent of this is then turned into bottom ash, which can be used as a construction material, for example,” explains Karin Karlfeldt Fedje.  </div> <div> </div> <div>Internationally, the prevalence of waste incineration is varied, but the need to handle large amounts of ash after the process is widespread. In Sweden, incineration of household waste in waste-to-energy plants is common, and results in around 250,000 tonnes of fly ash every year that could potentially be treated in this way. The rest of Europe accounts for around ten times that amount.    </div> <div> </div> <div>Although it is hard to estimate how many tonnes of zinc are currently lost through landfill in Sweden and beyond, the method developed by the Chalmers researchers can be of great interest to all waste management actors. It offers great potential for recovering these metals in a relatively simple way and could have a significant impact on the profitability of waste incineration, as well as its role in the circular economy.  </div> <div> </div> <div>  – The technology for extracting zinc from fly ash could have several positive effects, such as reducing the need for mining virgin zinc raw material, lower levels of toxicity in the ash, and greatly reduced landfill contributions.

The grant will be used to explore a new material that can both store solar energy and absorb energy from the environment and release it as heat.</b></p><p>​“It feels great, I'm both happy and proud, especially since this is a grant that you can only apply for every other year in very high competition” says <a href="/en/Staff/Pages/kasper-moth-poulsen.aspx">Kasper Moth-Poulsen</a></p> <p>The research that will be funded by the grant is similar to the solar energy system MOST (Molecular Solar Thermal Energy Storage Systems), which Kasper and his group have been working on for many years, and has attracted a great deal of attention around the world. But the new project is about developing the knowledge further and differs in several crucial ways. Now the researchers will work in systems with solid substances instead of in liquids as in MOST, and the material will be able to do several things at once.</p> <p>“We want to investigate whether it is possible to create a new material that can both store the sun's energy and absorb the energy or heat from the surroundings. In short, you might say that the overall purpose is to try to handle heat and, also cooling in a completely new way” says Kasper Moth-Poulsen.</p> <p>The material that the researchers are investigating must be sustainable and contribute to new emission-free solutions in energy storage.<br /></p> <p>In addition to Kasper Moth-Poulsen, Victor Torres Company at the Department of Microtechnology and Nanoscience was also awarded a consolidation grant from the Swedish Research Council.</p> <p><a href="/en/departments/mc2/news/Pages/Prestigious-funding-for-photonic-research-from-The-Swedish-Research-Council.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Prestigious funding for photonic research from The Swedish Research Council​​</a><br /></p> <h2 class="chalmersElement-H2">More about Kasper-Moth Poulsen </h2> <div>Kasper Moth-Poulsen is Professor and Head of Division at Applied Chemistry at the Department of Chemistry and Chemical Engineering and works with research in the field of nano chemistry and new materials for energy capture and storage and synthetic chemistry.

This scholarship may help to fund conferences, courses, or others, to support me to keep working on the use of solvent extraction to selectively recovery metals from lithium-ion batteries. I want to focus on more environmentally-friendly alternatives and on the optimization of the process to maximize the recovery of metals and reduce the use of energy and reagents in the process.”</div> <h2 class="chalmersElement-H2">Extract in English of Renova´s press release </h2> <div>Nathália Vieceli is researching on recycling metals from spent lithium-ion batteries at Chalmers in Gothenburg. There are essentially two methods for this. Pyrometallurgy, which is based on combustion. It is a stable method but requires large amounts of energy and normally some metals are lost in the process, such as lithium. Nathália Vieceli works to develop and refine the second method - hydrometallurgy - where the metals are instead dissolved in acid and extracted into various solvents. By experimenting with different parameters, she wants to find a process that requires as little energy and solvent as possible.</div> <div> </div> <div>In the press release she comments on the method: </div> <div>“An advantage is that you get the metals out with very high purity and content. The first step now is to extract manganese. Then the turn goes to cobalt, nickel and lithium” she comments in the press release and continues:</div> <div>“It is also important that the recycling process itself is sustainable, she points out. This method requires significantly less energy than combustion and we can use the same solvent over and over again” </div> <div><br /></div> <div>Renova's scholarship is SEK 100,000 and was awarded to Nathália Vieceli at Renova's sustainability seminar in Gothenburg on 14 October.</div> <div> </div> <div><a href="https://www.mynewsdesk.com/se/renova/pressreleases/renovas-stipendium-till-aatervinning-av-litiumjonbatterier-3042425" target="_blank">Whole press release in Swedish</a></div> <div><a href="/en/staff/Pages/nathalia-vieceli.aspx">More on Nathália Vieceli</a></div>Mon, 26 Oct 2020 00:00:00 +0100
