The proposals were both practical and dealt with advanced research questions. The subjects contained everything from Nano, VR and radar technology to infection prevention, management issues, and patients’ use of health apps.</div> <div><br /></div> <div><strong>Examples of subjects</strong></div> <div>•<span style="white-space:pre"> </span>Talk2Me – voice-based working methods </div> <div>•<span style="white-space:pre"> </span>Early stroke characterisation using video analysis</div> <div>•<span style="white-space:pre"> </span>Virtual Reality within healthcare </div> <div>•<span style="white-space:pre"> </span>Digital documentation for drop-in waiting rooms</div> <div>•<span style="white-space:pre"> </span>Patient-gathered health data to reach healthcare</div> <div>•<span style="white-space:pre"> </span>Meaningful user experience for citizens as well as healthcare professionals tracking individual health data</div> <div>•<span style="white-space:pre"> </span>Improving management of patient flows at various levels</div> <div>•<span style="white-space:pre"> </span>Management of patient groups with complex care needs: <span style="background-color:initial">Improving patient safety in real-time</span></div> <div><span style="background-color:initial"><br /></span></div> <div><strong>Increased demand for healthcare requires new working methods</strong></div> <div>Many of the project proposals regarded the needs in today’s and tomorrow’s healthcare.<br /><br /></div> <div>“We have a growing and aging population and because of advances in research and technological development, we can treat more severe diseases than before. This means that we get increased demand for healthcare, but the resources we have do not increase at the same rate. We need to manage that gap, for example by developing new working methods and tools, not at least linked to digitization, says Cecilia Hahn Berg, development strategist at Sahlgrenska University Hospital.<br /><br /></div> <div>Several of the proposals highlighted that there is a great need to transfer certain care from the hospital to the patient's home and to try to digitise and optimize time-consuming aspects of today’s healthcare, such as administration. An example of this involves voice-based working methods for ambulances. Other projects will investigate the possibility of working with fall detection, for example in the homes of elderly people. Another proposal was about developing an app to support diabetes patients in checking their own feet regularly to avoid the foot problems that are common in that patient group.<br /><br /></div> <div>Cecilia Hahn Berg is positive in regards to this year's fair also including bachelor's thesis.<br /><br /></div> <div>“It's great that the hospital, and researchers from both the University of Gothenburg and Chalmers are establishing contact between themselves and these students from start.

The cooperation between the universities also means that the students get the chance to work interdisciplinary with real projects, side by side with students and researchers with different competencies. In some cases, the students are supervised by researchers from both the clinical and technical side of health technology.<br /><br /></div> <div>One Chalmers professor who presented several proposals during the day was Göran Lindahl, director of the Centre for Healthcare Architecture, CVA.<br /><br /></div> <div>“The close collaboration with the healthcare sector, in this case Sahlgrenska University Hospital, gives us access to the actual operational challenges that the healthcare sector is facing, which creates relevance and provides inspiration.

Over the age of 70, more than 40 percent of the population will suffer from swallowing problem. Research shows that a diet with customized texture and taste makes swallowing easier for those, and that 3D printed food can make meals more appetizing, all with the help of materials science.</b></p><div>Insufficient food intake can have more causes than dysphagia, the medical term for swallowing disorders, but it is a very common problem for the elderly. It risks leading to age-related malnutrition that makes us more frail, which often leads to lack of independence, fall accidents and hospitalization. It not only causes suffering for the individual, but also entails great costs for society. In Sweden alone, the cost of age-related malnutrition is estimated to SEK 9 billion annually.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Konstruktionsmaterial/3D-printadmat_MatsStading_02.jpg" alt="Mats Stading" class="chalmersPosition-FloatRight" style="margin:5px 15px;width:367px;height:260px" />Mats Stading studies how materials science can be used to produce food that is easy to chew and swallow, but still resembles ordinary food as much as possible. It starts with producing a slow-flowing, so-called viscoelastic paste with different textures and flavors adapted to personal needs. 3D-printed food is produced by &quot;printing&quot; the paste into shapes similar to regular food, and then baking it to a firm, but easily chewable and swallowable consistency.</div> <div><br /></div> <div> </div> <div><br /></div> <div> </div> <div>“The research results clearly show that food consistency can be modified making it easier to both chew and swallow safely, and still remaining tasty. When combining this with 3D printing, we can produce exciting meals that look a lot like regular food”, says Mats Stading, adjunct professor at Chalmers.</div> <div> </div> <div><br /></div> <div><h2 class="chalmersElement-H2">The 3D-printer could be seen as any other kitchen appliance<br /></h2></div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Konstruktionsmaterial/3-printad%20broccoli.jpg" alt="broccoli" class="chalmersPosition-FloatRight" style="margin:5px 35px;width:244px;height:149px" />The idea is to be able to serve 3D printed food both in nursing homes and in a home environment. The technology exists and as has been proven to work, but there are a number of measures required for it to work in clinical or home setting. An important part is that food producers are involved and develop products that can be used on a larger scale.</div> <div><br /></div> <br /><div> “In the future, 3D printed food will probably be a regular feature, but initially extra support may be required if something goes wrong. The 3D printer's speed and specifications are still somewhat limited, but technology development is progressing quickly in this area”, says Astrid Ahlinder, researcher at RISE.</div> <div><br /></div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Konstruktionsmaterial/3D-printadmat_japambassador.jpg" alt="3d-printad mat visas" class="chalmersPosition-FloatLeft" style="margin:5px" /><br /><br /><em>The research is drawing great interest in Japan, which has the oldest population in the world. Here, Japan's ambassador gets a demonstration on how to 3D-print food.</em> </div> <div><br /></div> <div>The research is important because many countries have an increasingly high proportion of elderly, in Sweden 20 percent are over 65 and in Japan the corresponding figure is as high as 30 percent. Mats Stading has also collaborated with, among others, Japanese researchers regarding 3D printed food.</div> <div> </div> <div><br /></div> <div> “There is great interest in both countries, so it has been a natural collaboration. We also had the opportunity to combine the research on 3D-printed food with other studies that examine exercise and social interaction.

The forest has always been central for her, both for recreation and as a resource. Now she has become project manager for the newly started Bio innovation Program – Resource-Smart Processes – a national industrial graduate school. <br />The aim for this project is to increase knowledge of chemical and process technology, to make the processes more energy efficient and to make better use of the forest material.<br /><br /></span><div>“It is about using the forest more resource efficiently. We will reuse the structures we take from the forest today and convert into paper or textiles into clothes as building blocks for other materials, so that they spin around for many years. My goal as a researcher is that the resources should be used in a sustainable way. Sometimes you come up with solutions to take molecules out of the forest and then burn them - it is a waste of what nature has built. We can do that since the price for what we use haven´t been set right”, says Merima.</div> <div><br /></div> <div><strong>The core of what today constitutes</strong> Merima Hasani's great interest as a researcher at Chalmers was aroused at a young age at home in Varberg.</div> <div>“Even as a child, I wanted to understand how things are built on a molecular level. I grew up with a mother who was a chemistry and biology teacher, and I was fascinated by molecules. It is somehow the core of everything”.</div> <div>During high school, her interest in technology was also aroused.</div> <div>“I came to the conclusion that if you should apply chemistry and create new molecules, you should combine it with something more, so I applied for an education that allowed me to connect it with something that was applicable”.</div> <div><br /></div> <div>“To be honest, when I look back to when I applied to Chalmers in 1999, I did not really know what chemical engineering was - but it allowed me to apply chemistry on a larger scale. That's how it started”.</div> <div>Merima Hasani started her studies at Chalmers in the autumn of 1999. In October 2010, she defended her doctoral theses in Organic Chemistry with the title &quot;Chemical modification of cellulose - new possibilities of some classical routes&quot;. <br /><br /><strong>Merima had studied the possibility</strong> to give cellulose fibers new functionality and thereby create conditions for new or improved product properties. For that, she was awarded the 2011 Competence Development Award. In the same year, the trip went to Austria and the University of Natural Resources and Life Sciences, BOKU, in Vienna, which has a leading research group in this field. <br />In 2016 she was awarded Future research leader by Formas. With that, she deepened her knowledge and the work with new concepts for dissolution and transformation of cellulose as an alternative and more environmentally friendly way to, among other things, create textile fibers.</div> <div>Since 2014, Merima has been connected to the Wallenberg Wood Science Center - a collaboration between The Royal Institute of Technology (KTH), Chalmers University of Technology, Linköping University, and the forest industry. The center has built up deep knowledge of how the tree's constituent parts – cellulose, hemicellulose and lignin – can be separated and used in new materials.<br /><br /></div> <div><strong>“The Resource-smart Processes program </strong>and the Wallenberg Wood Science Center complement each other. The industry has realized the importance of investing in both”.</div> <div> “Wallenberg Wood Science Center is very focused on fundamental research towards the development of new materials based on forest biomass. In Resource-Smart processes, we focus on building the knowledge needed to be able to produce these materials”, says Merima Hasani.<br /><br /></div> <div>Process engineering knowledge in Sweden regarding separation and valorization of forest biomass is world-leading, but there has been a major loss in the area. Twenty years ago, Chalmers really had the skills and good momentum in that business. But since then, several professors have retired without new recruitment. This was noticed by Hans Theliander, professor of Forest Industrial Chemical Engineering at Chalmers, Daniel Söderberg from KTH and Torgny Persson, Forest Industries. The three are the key people, together with the industry behind &quot;Resource-smart processes&quot;. <br />In January this year, the business graduate school kicked off with the goal of strengthening process engineering research and education in Sweden. The program has eleven doctoral students and postdocs and is funded by Bio Innovation, industry, and academia.<br /><br /></div> <div><strong>Now Merima Hasani has taken over as coordinator</strong></div> <div>“Hans Theliander and I have worked together for a long time, he is one of the brains behind the program and has made a big impression”, she says.</div> <div>All projects in &quot;Resource-smart Processes&quot; are led by research leaders within the academy, while the research issues are developed together with industry. Several of the projects involve several different industry partners.</div> <div>“It is fun for us and the doctoral students to work close to the industry and feel the commitment that exists, and that their research can contribute to benefit the society. Within the program, we put competition aside to build knowledge that everyone benefits from - to move forward faster. Then we must agree on the major research issues”, says Merima.<br /><br /></div> <div><strong>So, what hasn´t been that smart previously?</strong></div> <div>“It is above all the processes linked to renewable resources, the forest biomass. They should help us manage the wood raw material and the energy in the best possible way. That’s why it is important to think about, streamline and reuse”.</div> <div>With chemical and process technical knowledge, it is possible to optimize and redesign the processes, make them more energy efficient and utilize the forest material better, get a better material production yard simply.</div> <div> <br /><strong>This is about many things.</strong></div> <div>“In other words, the energy issue has always been an important part of the strategic thinking around process development. It is always included in our discussions and analyzes. Now it's more important than ever. Even the forest debate - before the Ukraine war - put everything at its peak. So again. We must be extremely careful with what we get from the forest so that every green structure, with every carbon atom is used in the best way. We must ensure that as much as possible can be reused. Resource efficiency and circularity are very important. That is the direction we must have in the future. I can´t see any other way”, says Merima Hasani.<br /><br /><div><a href="/sv/personal/Sidor/merima-hasani.aspx" style="outline:0px"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" /></a><a href="https://www.bioinnovation.se/resurssmartaprocesser/">The Industrial graduate school Resource-smart Processes</a></div> <div><a href="https://wwsc.se/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Wallenberg Wood Science Center</a></div> <div><a href="/sv/personal/Sidor/merima-hasani.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Merima Hasani</a></div> <br />Text: Ann-Christine Nordin</div>Wed, 06 Jul 2022 00:00:00 +0200https://www.chalmers.se/en/departments/see/news/Pages/Pioneering-recycling-turns-mixed-waste-into-premium-plastics-with-no-climate-impact.aspxhttps://www.chalmers.se/en/departments/see/news/Pages/Pioneering-recycling-turns-mixed-waste-into-premium-plastics-with-no-climate-impact.aspxPioneering recycling turns mixed waste into premium plastics with no climate impact<p><b>​Only a fraction of the material that could be turned into new plastic is currently recycled.

Henrik Thunman and his research team want to focus on an important resource that often goes up in smoke today: the carbon atoms in our waste, which are currently incinerated or end up in landfills instead of being recycled. This is made possible with technologies targeting the carbon contained in plastic, paper and wood wastes, with or without food residues, to create a raw material for the production of plastics with the same variety and quality as those currently produced from fossil raw materials. </div> <div><br /></div> <div><strong>Just like nature </strong></div> <div>Current plastic recycling methods are able to replace no more than 15-20% of the fossil raw material needed to meet society’s demand for plastic. The advanced methods proposed by the researchers are based on thermochemical technologies and involve the waste being heated to 600-800 degrees Celsius. The waste then turns into a gas, which after the addition of hydrogen can replace the building blocks of plastics. Using this recycling method could decouple new plastic products from the supply of new fossil raw materials.</div> <div>The researchers behind the study are developing a thermochemical recycling method that produces a gas which then can be used as a raw material in the same factories in which plastic products are currently being made from fossil oil or gas. Different types of waste, such as old plastic products and paper cups, with or without food residues, are put into the reactors at the Chalmers Power Central.</div> <div><br /></div> <div>“The key to more extensive recycling is to look at residual waste in a whole new way: as a raw material full of useful carbon atoms. The waste then acquires value, and you can create economic structures to collect and use the material as a raw material worldwide,” says Henrik Thunman. </div> <div>The principle of the process is inspired by the natural carbon cycle. Plants are broken down into carbon dioxide when they wither, and carbon dioxide, using the sun as an energy source and photosynthesis, then creates new plants. </div> <div><span style="background-color:initial">“H</span><span style="background-color:initial">owever, our technology differs from the way it works in nature because we don’t have to take the detour via the atmosphere to circulate the carbon in the form of carbon dioxide.

Competition horses develop the disease very early as a result of intensive training at a young age. As part of a large collaborative project between the Swedish University of Agricultural Sciences (SLU) and Sahlgrenska University Hospital (SU), researchers at Chalmers have been involved in developing a new method to enable early diagnosis of osteoarthritis in horses.</b></p><div>“Osteoarthritis is a chronic joint inflammation where the disease process is slow and difficult to diagnose at an early stage. But to be able to treat it, it is important to identify the early stages”, says Eva Skiöldebrand, professor of general pathology at the Swedish University of Agricultural Sciences (SLU) with a focus on osteoarthritis in horses and humans.<br /><br /></div> <div>“Together with professors Stina Ekman at SLU and Anders Lindahl at SU, our research group has developed biomarkers, or more specifically, identified new neoepitopes* that are generated when protein from articular cartilage and underlying subchondral bone (bone under articular cartilage) is broken down by inflammation, which is the hallmark of the disease. The research group has been able to verify the biomarkers in serum and synovial fluid in horses with varying degrees of osteoarthritis and studied the effect of training and the effect of circadian rhythm, which is a major research breakthrough, says Eva Skiöldebrand.<br /><br /></div> <div>The use of biomarkers allows the disease to be detected earlier and the occurrence of serious injuries to be prevented – and the effectiveness of drugs for the treatment of osteoarthritis can be evaluated.</div> <div><br /></div> <div><strong>Early diagnosis with saliva test</strong></div> <div><img src="/SiteCollectionImages/Areas%20of%20Advance/Health/Udda%20format/Artros_bild_450x350.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />One person who has played a large part in a related research breakthrough at the end of 2021 is Moa Lord, a former biotechnology student and now a research assistant in materials physics at Chalmers. <span style="background-color:initial">Together with the research group at SLU and SU, she has developed a new method for quantifying biomarkers in saliva in horses, under the supervision of professor Eva Skiöldebrand, Susanne Nyström, PhD in molecular biology, BMA at SU, and Magnus Karlsteen, associate professor of materials physics at Chalmers and responsible for Chalmers' initiatives in equine technology.</span></div> <div><br /></div> <div>“We wanted to develop a method that could easily fit into the daily horse keeping. Saliva sampling is a non-invasive sampling method in contrast to synovial fluid samples and blood samples, which means that you can take more samples without creating discomfort in the horse. Detection and quantification of the biomarker in saliva enables an easier way to monitor how the biomarker is affected by training and surfaces, and detection of early signs of disease”, says Moa Lord.<br /><br /></div> <div><strong>Self-developed bit for horses</strong></div> <div>To facilitate saliva sampling, Chalmers has refined the method by producing a special bit for horses.</div> <div>“When we discovered that we could use saliva to measure the biomarker, we wanted to investigate how the biomarker changes during a training session when the strain on the joint increases. That is why we at Chalmers have designed and constructed a bit with space for sampling tubes. The bit collects the saliva while riding or driving the horse. This enables us to collect samples in a simpler way and that the training session can be completed without a major interruption to take a sample”, says Moa Lord.<br /><br /></div> <div>“This bit and the ability to detect the biomarker in saliva is the basis for a completely new diagnostic method, there is no one who has done something similar before. The current test tubes in the saliva collection bit work well. But we are working for the long-term goal of implementing an electronic graphen sensor e in the bit, which can provide continuous measurement values of the biomarker and test results directly on site. This would enable the horse owner from home to consult with a veterinarian and follow the development of the disease and act by working preventively to eliminate incipient disease”, says Magnus Karlsteen.<br />​<br /></div> <div>“Considering that a large number of competition horses develop osteoarthritis, the bit is important for the preventive work. Being able to measure the biomarker in saliva means that we can measure the effect of training when the horse runs and rides on different surfaces and at different paces. Then you can tailor training programs that will not harm the joints and hopefully it can result in fewer horses developing the disease”, says Eva Skiöldebrand.<br /><br /></div> <div><strong>Continued funding of the project</strong></div> <div>Moa Lord’s project &quot;Can we use saliva to detect osteoarthritis in the horse?&quot; has been part-financed by the Health Engineering Area of Advance at Chalmers. At the beginning of 2022, The Swedish Association for the Protection of Animals granted funding to investigate the presence of pain biomarkers in the saliva of horses. “The presence of pain biomarkers in saliva can provide an enormous amount of information about the horse's pain status and we are incredibly grateful for this research money”, says Eva Skiöldebrand.<br /><br /></div> <div>“The success of this research project is fantastically gratifying and hopeful for the diagnosis and prevention of osteoarthritis in horses, but also in humans in the future”, says Martin Fagerström, Co-Director of Health Engineering Area of Advance at Chalmers.<br /><br /></div> <div><strong>Joint commitment to horse welfare</strong></div> <div>The collaboration between Eva Skiöldebrand, SLU, and Magnus Karlsteen and Moa Lord at Chalmers has, among other things, its background in a common interest in equestrian sports and a strong commitment to horse welfare. Their paths have, among other things, been crossed at the Chalmers fence, an event in connection with the World Cup competitions in horse jumping in Gothenburg, with Magnus Karlsteen as responsible.</div> <div><br /></div> <div><strong>Reinforced focus on sports technology</strong></div> <div>According to the International Horse Sports Confederation, Chalmers is world leading in equestrian technology.<br /><span style="background-color:initial"><br />From 1 August 2022, Chalmers will be the first national sports university in Sweden to become a competence centre for sports technology.

At Chalmers University of Technology, Sweden, a research team has created a unique method for further developing hydrofoils that can significantly increase the range of electric vessels and reduce the fuel consumption of fossil-powered ships by up to 80 per cent.</b></p>​<span style="background-color:initial">While the electrification of cars is well advanced, the world's passenger ferries are still powered almost exclusively by fossil fuels. The limiting factor is battery capacity, which is not enough to power ships and ferries across longer distances. But now researchers at <strong>Chalmers and the marine research facility SSPA</strong> have succeeded in developing a method that can make the shipping industry significantly greener in the future. The focus is on hydrofoils that, like wings, lift the boat’s hull above the surface of the water and allow the boat to travel with considerably less water resistance. A technology that in recent years has revolutionised sailing, by which hydrofoils make elite sailors' boats fly over the surface of the water at a very high speed. <br /></span><div>The researchers at Chalmers and SSPA now want to enable the sailboats' hydrofoil principle to be used on larger passenger ferries as well, resulting in enormous benefits for the climate. <br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Arash%20200x200.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 15px" /><br /><span style="background-color:initial"><strong>&quot;</strong></span><span style="background-color:initial"><strong>The electrification of ferries cannot be done</strong> without drastically reducing their water resistance. This method will allow the development of new foil designs that can reduce resistance by up to 80 per cent , which in turn would significantly increase the range of a battery powered ship. In this way, we could also use electric ferries on longer distances in the future,&quot; says research leader <strong>Arash Eslamdoost</strong>, Associate Professor in Applied Hydrodynamics at Chalmers and author of the study Fluid-Structure Interaction of a Foiling Craft published in the Journal of Marine Science and Engineering.</span><br /></div> <div><br /></div> <div>Even for ships that today run on fossil fuels the climate benefit could be enormous, as similar hydrofoil technology could reduce fuel consumption by no less than 80 per cent. <br /></div> <h2 class="chalmersElement-H2">Unique measurement method arouses broad interest </h2> <div>At the centre of the research project is a unique measurement technique that the researchers have put together in order to understand in detail how hydrofoils behave in the water when, for example, the load or speed increases or the positioning of the hydrofoil changes. Using the data collected from the experiments, the team has developed and validated a method to simulate and predict with great precision how the hydrofoil would behave under a variety of conditions. The method is unique of its kind and can now be used to develop the design of hydrofoils for electric powered hydrofoil ferries.<br /></div> <div><br /><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/Laura%20200x200.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px 15px" />The study was conducted in collaboration with the research facility SSPA – one of only a few of its kind in the world – where <strong>Laura Marimon Giovannetti</strong> works as a researcher and project manager. She is the lead author of the study and has herself competed at the elite level for both the British and Italian national sailing teams. Today she is a research and development adviser to Sweden's Olympic committee and the Swedish national team with her sights set on helping the team win more medals at the Olympics in 2024. Marimon Giovannetti sees many possibilities for the unique measurement method developed by the team: </div> <div><br /></div> <div><div><strong>&quot;At the Americas Cup in San Francisco Bay in 2013</strong>, it was the first time we saw a 72-foot sailing boat learning how to “fly” using hydrofoils during the competition. And since then, we've seen a huge increase in sailing boats with hydrofoils. With this new method and knowledge we are able to bring together a range of different branches of engineering – naval architecture, advanced materials and aeronautics as well as renewable energy.&quot;</div></div> <h2 class="chalmersElement-H2">Paving the way for hydrofoils on electric ferries </h2> <div>Hydrofoil technology is not in itself a novelty, but was developed as early as the 60s and 70s. Back then the focus was on getting boats to travel at as fast as possible and the hydrofoils were made of steel, a heavy material with higher maintenance costs. Today's modern hydrofoils are made of carbon fibre, a much lighter and stiffer material that can maintain its rigidity even under high loads – and can be tailored to the expected loads. Part of the research project was therefore to fully understand how a carbon fibre structure behaves underwater during different operational conditions. The research team's method developed in association with modern technology is now paving the way for the use of carbon fibre hydrofoils on larger passenger ships that can travel in a safe, controlled and climate-friendly way even at low speeds. <br /><br /></div> <div><strong>&quot;You want the foil to be as efficient as possible</strong>, which means carrying as much weight as possible at as low a speed as possible with the least resistance. Our next goal is to use this method when designing more efficient hydrofoils for ferries in the future,&quot; says Eslamdoost.</div> <div><br /></div> <div><strong>More about the scientific article </strong></div> <div>The study <a href="https://www.mdpi.com/2077-1312/10/3/372">&quot;Fluid-Structure Interaction of a Foiling Craft&quot;</a> has been published in the Journal of Marine Science and Engineering.

It is the backbone of all electronic screen​s (LCD, LED, and touch screens), and some solar cell technologies. During the manufacturing of these devices, 30 - 70% of the material becomes production waste. Almost 75% of indium is used for ITO manufacturing and it is accepted as a critical raw material due to its importance in the electronic industry. It is a minor element of the earth’s crust and is unevenly distributed. It's recycling from industrial waste is challenging and requires several stages. In our technology, indium recovery is simplified instead of complicated processing stages and integrated into the ITO powder production to reproduce ITO material.​</span><strong><br /></strong></p> <p class="chalmersElement-P"><span style="background-color:initial">Researcher: </span><a href="/en/staff/Pages/Burcak-Ebin.aspx">Burcak Ebin</a></p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"><a href="/en/staff/Pages/Burcak-Ebin.aspx"></a>Project: <strong>High-Quality Graphene and Highly Thermal Conductive Graphene Films Produced in Eco-friendly ways</strong><br /></p> <p class="chalmersElement-P"><strong></strong><span style="background-color:initial">The heat generated from ubiquitous miniaturized electronic devices needs to be dissipated by materials that are highly thermally conductive, lightweight, flexible, mechanically robust and, most importantly, manufactured in a sustainable way.
