News: Livsvetenskaper och teknik related to Chalmers University of TechnologyWed, 01 Dec 2021 19:20:40 +0100 lab will provide better diagnosis and treatment of diseases<p><b>Better diagnosis and treatment of a wide range of diseases – everything from stroke and epilepsy to cancer and trauma. That is the goal of the new research laboratory Sahlbec, which is now inaugurated. ​</b></p>​<span style="background-color:initial">The lab will be used for two promising techniques. The use of microwaves for medical purposes, and the use of superconducting sensors to register the extremely weak magnetic fields generated by electrical signals in the body.</span><div><br /></div> <div>In a technical sense, it can be said that Sahlbec lab is about achieving maximum shielding. This applies to electric and magnetic fields. <span style="background-color:initial">But from another point of view, the purpose is the exact opposite. Namely to integrate medical technology research at Chalmers University of Technology and the University of Gothenburg with the activities at Sahlgrenska University Hospital. Not least to make it easier for patients participating in clinical trials. </span><span style="background-color:initial">That is why the location of the laboratory is so important.</span></div> <div><br /></div> <div>&quot;And the location has really become incredibly good. Just a few steps to the right behind the hospital's main entrance, right next to the radiology,&quot; says Henrik Mindedal, Director of MedTech West. He is the Project Manager for the new laboratory, which with peripherals and installations cost just over SEK 15 million to build.</div> <div><br /></div> <div>The laboratory is as large as a normal studio apartment and about half the area is the facility's main area: The screened room. <span style="background-color:initial">A room with floor, walls and ceiling which consist of several layers of aluminium and so-called Mu metal, placed at certain mutual distances from each other. </span><span style="background-color:initial">What is achieved with this unique construction technology is a room that effectively stops both electromagnetic radiation – for example radio waves – and magnetic fields. </span><span style="background-color:initial">And the shielding works in both directions.

However, currently, less than half of the grains are used for human consumption. Changes in grain consumption and novel cereal protein-enriched food innovations could play a major role in transitioning towards a more sustainable food system for healthy diets, conclude Nordic researchers in a joint review published in Nutrition Reviews.​</b></p><p class="chalmersElement-P">​<img src="/SiteCollectionImages/Institutioner/Bio/Food/rikard_200.jpg" alt="Rikard Landberg" class="chalmersPosition-FloatRight" style="margin:10px" /><span>“Both scientists and public seem to have missed the yet untapped potential that grains can contribute towards a more sustainable food system and a healthier population. Even small changes in dietary patterns could make a large difference both to environment and health and grains could represent one of these possibilities,” says Professor <strong>Rikard Landberg</strong> from the Division of Food and Nutrition Science at Charlmers.  </span></p> <p class="chalmersElement-P">Food production is responsible for 26 per cent of global greenhouse gas emissions. Increased use of plant-based foods to replace animal-based foods such as meat and dairy is one of the strategies to meet sustainability targets. This includes improving human health, particularly in the Western world. </p> <h2 class="chalmersElement-H2">Which foods should replace meat?</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">A joint consortium of researchers within food, nutrition, environment and medicine from Nordic Universities and institutes developed a pot​ential scenario to reduce meat intake in Europe and replace it with more sustainable and healthier whole grain-based foods. Which foods shall be used and what are the nutritional consequences and the implications for the environment?</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“In our scenario, if 20 per cent of the current daily European animal protein intake was to be replaced by plant-based protein, 50 per cent could come from cereals. This would mean less than 6 grams more cereal protein daily, corresponding to a serving of 60 grams of grains” says Senior Adviser Kaisa Poutanen, VTT Technical Research Centre of Finland. </p> <p class="chalmersElement-P">The current cereal protein intake would need to be increased by 19 per cent. With an average content of 10 per cent protein in grains, this would mean an additional need of 15 million tons of grains, which corresponds to 5 per cent of the current European grain production. </p> <h2 class="chalmersElement-H2">Three slices of bread extra per day</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“Since only one third of the current grain production is used for human consumption, there is a possibility to switch from animal feed production to human consumption if consumers would accept it. Such transition would correspond to an increased consumption of about 60 grams per day – for example three slices of whole-grain rye bread or a large portion of oatmeal,” says Anna Kårlund, Postdoctoral researcher at University of Eastern Finland. </p> <h2 class="chalmersElement-H2">Increased intake of legumes also needed</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Whole grains are beneficial to health and a high intake has consistently been associated with reduced risk of developing type 2 diabetes, coronary heart disease and colorectal cancer in observational studies. Whole grains are rich in dietary fibre, vitamins, minerals, and bioactive compounds, but grain protein contains low amounts of the essential amino acid lysine. Therefore, the nutritional composition of the overall diet should be highlighted to ensure an optimal amino acid intake. This can easily be done by increased intake of legumes to complement cereal protein.  </p> <h2 class="chalmersElement-H2">The industry must be engaged and stimulated ​</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Furthermore, a strong future focus from the industry on processing and product design will benefit both society and industry.  </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Increased availability and use of new protein-rich cereal food concepts, including dairy and meat analogues with well-balanced nutrition profiles, along with a shift towards more whole grain traditional cereal food, could help in the transition towards healthier and more sustainable diet. </p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"><strong>Read the publication in Nutrition Reviews:</strong> <a href="">Grains – a major source of sustainable protein for health</a></p> <p class="chalmersElement-P"></p> <p class="chalmersElement-P"></p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><strong>The authors:</strong></p> <p class="chalmersElement-P"> </p> <div><ul><li><p class="chalmersElement-P">Kaisa Poutanen, VTT, Finland</p></li> <p class="chalmersElement-P"> </p> <li><p class="chalmersElement-P">Anna Kårlund, University of Eastern Finland, Finland</p></li> <p class="chalmersElement-P"> </p> <li><p class="chalmersElement-P">Carlos Gómez-Gallego, University of Eastern Finland, Finland</p></li> <p class="chalmersElement-P"> </p> <li><p class="chalmersElement-P">Daniel P.

The UN SDG 6 spells “Clean water and sanitation”, and the World Toilet Day aims at celebrating toilets and to raise awareness of the severe problems connected to deficient sanitation systems. Theme of 2021 is” Sustainable sanitation and climate change”. But what is the connection between sustainable sanitation systems and climate change? And how can research contribute?</b></p><div>​   – A well-functioning sewage system where wastewater is transported and treated in an efficient, hygienic, and environmentally friendly way is fundamental to protect the environment and human health, says Professor Britt-Marie Wilén, Department of Architecture and Civil Engineering.    </div> <div> </div> <div> </div> <div> </div> <div>Climate change causes droughts, floods and rising sea levels, which threatens our sanitation systems in various ways. Floodwaters can spread human waste to drinking water sources and food crops and cause disease. Discharges of wastewater can also lead to eutrophication, which causes fish and aquatic plants and animals to die.    </div> <div> </div> <div> </div> <div> </div> <div>For Sweden’s part, increasing amounts of precipitation effect society as pipes and treatment plants aren’t dimensioned for an inflow that sometimes increases tenfold, which leads to an overflow in the sewage systems where polluted wastewater is discharged into the environment.    </div> <div> </div> <div> </div> <div> </div> <div>   – In countries that do not have sewage systems to the same extent, dry latrines can even be a better solution. In Sweden we have functioning systems that purify to a very high degree. What we are studying is how we can improve the processes further in terms of emission quality and energy consumption. Already today we extract energy from wastewater in the form of biogas, and in the future we may even be able to develop energy-neutral treatment plants. If we can find environmentally friendly, compact and resource-efficient processes, we can in the long run contribute to better sewage treatment and applications in countries with less developed systems, Britt-Marie Wilén comments.    </div> <div> </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">Bacteria do the job</h2> <div> </div> <div> </div> <div> </div> <div>With her promotion in 2021, Britt-Marie Wilén became Chalmers first female professor in the water and sanitation area**. She has a solid background at Chalmers and is part of the research theme of wastewater treatment and resource recovery (Bioresource Labs) in the Division of Water Environment Technology, with “Bio” being the key to sustainable wastewater treatment, according to Britt-Marie.    <img src="/SiteCollectionImages/Institutioner/BoM/Profilbilder/Vatten%20Miljö%20Teknik%20-%20profilbilder/Britt-Marie-Wilen.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /></div> <div> </div> <div> </div> <div> </div> <div>   – Purification with biological processes is based on bacteria doing the work of purifying the water. We don’t add any bacteria but create conditions in the treatment plant to make the bacteria from human faeces, as well as those that come in with stormwater and leakage into the pipe network, thrive and flourish.    </div> <div> </div> <div> </div> <div> </div> <div>A common method for purification where bacteria play an important role is the so called” activated sludge process”, where dissolved organic and inorganic substances in the wastewater, such as nitrogen and phosphorus, are converted into particles that can be separated. The bacteria grow and become sludge, and the sludge can, after purifying the wastewater, be used for biogas by digestion.    </div> <div> </div> <div> </div> <div> </div> <div><h2 class="chalmersElement-H2">Compact and efficient cleaning processes create sustainability</h2></div> <div> </div> <div> </div> <div> </div> <div>The goal for the researchers is thus to develop as resource-efficient, compact and environmentally friendly purification processes as possible. Like minimizing the use of chemicals and energy by reducing the amount of pumping and adding of oxygen, and to build less space-consuming purification processes. Through research, one can understand the processes better and make them more efficient, and thus move forward on the road to a more sustainable sewage management.    </div> <div> </div> <div> </div> <div> </div> <div>   – We try to understand what affects which bacteria can be found in the treatment plant and what they do. In this way, we can create conditions that make them thrive. We know, for instance, that bacteria like to grow together to assimilate nutrients in an easier way. We test different growth environments and growing methods such as granular sludge and biofilm where the bacteria grow close together. If you understand which bacteria do the job and how, then you can also understand how to control different parameters in a treatment plant, explains Britt-Marie.    </div> <div> </div> <div> </div> <div> </div> <div>The researchers at Chalmers collaborate with the municipal company Gryaab in the treatment plant Ryaverket in Gothenburg. The group is also looking at how to generate energy from wastewater, through so-called microbial electrochemical cells, a technique still at a research level, but in the long run could enable for treatment plants to generate their own energy in an even more efficient way, compared to current technology with digestion of sludge to biogas.    </div> <div> </div> <div> </div> <div> </div> <div>Other important research is about understanding how drug residues can be taken care of in the treatment plant – and also for this purpose, bacteria can be part of the solution.    </div> <div> </div> <div> </div> <div> </div> <div>   – We consume more and more drugs, which means that drug residues end up in the wastewater. This is a real problem because it has been shown to be related to hormonal disorders in fish and aquatic organisms, and cause antibiotic resistance  says Britt-Marie.    </div> <div> </div> <div> </div> <div> </div> <div>All water in nature is connected and becomes part of the natural cycle, and sewage treatment is thus important to protect all water in society.    </div> <div> </div> <div> </div> <div>By: Catharina Björk<br /><br /></div> <div> </div> <div>*3.6 billion people do not have access to a safely managed sanitation service (WHO/UNICEF 2021)  </div> <div> </div> <div>** Ann Mattsson is employed by Gryaab AB and was appointed adjunct professor in water and sewage technology in Chalmers by 2013.    </div> <div> </div> <div> </div> <div> </div> <div><a href="">Read more about the World Toilet Day and SDG6</a><br /></div> <div> </div> <div> </div> <h3 class="chalmersElement-H3">Read more about the research in the wastewater treatment area</h3> <div> </div> <div><a href="">Publications by Britt-Marie Wilén and colleagues </a> </div> <div> </div> <div><a href=";query=&amp;f_funder=&amp;f_person=&amp;f_organization=&amp;f_organization_country=&amp;f_is_public=&amp;f_is_verified=&amp;f_local_orgs_level_2=c3ea27a9-c971-4fe4-b7b7-608f000452b1%7cVatten+Milj%u00f6+Teknik">Research projects of the Division of Water Environment Technology    </a></div> <div>Read more about bacteria: <a href="/en/departments/ace/news/Pages/New-method-helps-us-understand-natures-sanitation-workers.aspx">&quot;New method helps us understand nature's own sanitation workers&quot;</a><br /></div>Fri, 19 Nov 2021 07:00:00 +0100 Professor on Highly Cited Researchers list<p><b>​Jens Nielsen, Professor of Systems Biology, is on the Highly Cited Researchers list −​ a list of the most cited, and thereby most influential, researchers in the world. </b></p><p class="chalmersElement-P">​<span>The <a href="">Highly Cited Researchers</a> list identifies scientists who have demonstrated significant influence through publication of multiple highly cited papers during the last decade.

One idea is to develop foods that contribute to an increased feeling of fullness and have positive effects on metabolism.</p> <p class="chalmersElement-P"><span style="background-color:initial">Previous studies have observed that those who eat rye, which has a very high content of dietary fibre, feel more full than those who eat the corresponding amount of energy in the form of refined wheat. One of the purposes of this study was therefore to investigate this potential link between increased intake of rye and weight loss.</span></p> <p class="chalmersElement-P"><span style="background-color:initial">“But surprisingly, in this study, we actually never observed any difference in appetite. We think this may be simply because the method we used to measure appetite was not go​od enough. We are therefore working on evaluating and developing the method further,” says Kia Nøhr Iversen.</span></p> <p class="chalmersElement-P"><span style="background-color:initial">In order for a food to be marketed with specific health claims, a series of rigorous studies must be carried out to prove the effect. These studies are costly and represent a barrier to obtaining the scientific evidence needed, making it less attractive in turn for food producers to develop and market products that could contribute to reducing excess weight and obesity. </span></p> <h2 class="chalmersElement-H2"><span>Simple advice for consumers</span></h2> <p class="chalmersElement-P"><span style="background-color:initial">“A particularly positive aspect of our study is that the rye products we used are easily attainable in normal supermarkets in Scandinavia and most of Europe. Consumers can therefore act on the new results immediately. It does not require particular effort or dedication to have a diet rich in whole grain rye”, says Kia Nøhr Iversen.</span></p> <p class="chalmersElement-P"><span style="background-color:initial">The researchers caution that there is more work needed before they can show in detail exactly what mechanisms determine why whole grain rye is good for weight loss at the individual level. But the results of the new study already demonstrate a causal link between rye intake and weight loss through fat reduction, and studies to determine the mechanisms behind this link are already under way. </span></p> <p class="chalmersElement-P"><span style="background-color:initial">“As we continue to look for the exact reasons why, our advice is to choose the rye bread instead of the sifted wheat bread,” says Kia Nøhr Iversen.</span></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><strong>More detailed info about the research</strong></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"></p> <ul><li>The scientific article <a href="">‘A hypocaloric diet rich in high fibre rye foods causes greater reduction in body weight and body fat than a diet rich in refined wheat: A parallel randomized controlled trial in adults with overweight and obesity (the RyeWeight study)’</a> has been published in Clinical Nutrition.

These high doses result in side effects on other organs.</span></p> <p class="chalmersElement-P"><span style="background-color:initial">“In order to use the immune system optimally, more intelligent therapies, that can direct the drugs to the right area, at the right concentration, and at the right time, are needed,” says Alexandra Stubelius. </span></p> <h2 class="chalmersElement-H2"><span>Three different strategies​</span></h2> <p class="chalmersElement-P"><span style="background-color:initial">Alexandra Stubelius explains that her team uses three different strategies to develop smarter nanomedicines.</span></p> <p class="chalmersElement-P"><span style="background-color:initial">First, they develop new materials, nanovesicles, that can carry existing anti-inflammatory drugs. The materials are designed to target the inflammation and deliver the drugs without damaging the surrounding tissue. </span></p> <p class="chalmersElement-P"><span style="background-color:initial">The second strategy is to create nanomaterials that can modulate the immune system. The nanomaterial acts as active substance that affects the immune response.  </span></p> <p class="chalmersElement-P"><span style="background-color:initial">“With this method, we can fight inflammation in a new way. We aim to interfere with the communication signals of immune cells already in the blood stream. This inhibits more immune cells to be recruited to the affected tissue and prevents the inflammation from getting worse.”</span></p> <p class="chalmersElement-P"><span style="background-color:initial"></span><span style="background-color:initial">The third strategy is based on the discovery that the immune system not only defends out bodies, but also heals damaged tissue. The researchers examine which components that affects the immune cells in the healing process. The identified components can then be used to continue develop smarter materials for more specific immune-regulating therapies.</span></p> <p class="chalmersElement-P"><span style="background-color:initial">“The grant I have been awarded by the Hasselblad Foundation will mainly go towards hiring a postdoc that can help me achieve my goal of smarter immunotherapies,&quot; says Alexandra Stubelius.</span></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><span style="background-color:initial"><strong>Text: </strong>Susanne Nilsson Lindh<br /></span><span style="background-color:initial"><strong>Photo:</strong> Hasselblad Foundation </span><span style="background-color:initial"><br /></span></p> <p class="chalmersElement-P"><span style="background-color:initial"><strong>More about: </strong></span></p> <p class="chalmersElement-P"></p> <ul><li><span style="background-color:initial"><a href="/en/departments/bio/research/chemical_biology/Stubelius-lab/Pages/default.aspx">Alexandra Stubelius research</a><br /></span></li> <li><span style="background-color:initial"><a href=""><span>The Hasselblad Foundation grant for female scientis</span>ts</a><br /></span></li></ul> <p></p> <div> </div> <div>​<br /></div> <div> </div>Thu, 30 Sep 2021 08:00:00 +0200<p><b>​With the new Chalmers initiative, CHAIR aims to establish an instrument that allows Chalmers-based researcher in any field (X) with a strong international standing to develop an environment that leverages AI to reach global excellence. ​​</b></p><strong>​</strong><span lang="EN-US"><span><strong>Karinne</strong></span><span><strong> Ramirez-Amaro, Assistant Professor at Electrical Engineering, is part of the working group that developed the call. <br /><br /></strong></span></span><div><span lang="EN-US"><span lang="EN-US"><span><em>What kind of collaboration and science is it that CHAIR hopes come out of the call?</em></span></span><span><em> <br /></em></span><span><strong><br /></strong></span></span></div> <div><span lang="EN-US"><span lang="EN-US"><span>This call aims to find one or more research topics (X) that can be combined with AI in a way that unifies and excites excellent research groups at Chalmers.

The topic is &quot;Additive Manufacturing – From academic challenges to industrial practice&quot;. The event will take place online, November 17th, with several internationally recognized speakers. ​</b></p>​​<img src="/en/areas-of-advance/materials/news/PublishingImages/Uta-Klement_MFT.jpg" alt="Uta Klement" class="chalmersPosition-FloatRight" style="margin:5px" /><span style="background-color:initial"><strong>“There is a very close </strong>cooperation between academia and industry. This is also reflected in CAM2, the Centre for Additive Manufacture – Metal, in which around 25 companies are involved and help define research questions”, says Uta Klement, and she continues:</span><div><br /></div> <div>“To achieve the United Nations SDGs, we need to fundamentally change the way we live, including the way we manufacture products. Additive manufacturing contributes to resource efficiency by reducing material waste and energy consumption. Additive manufacturing, AM, can also help to produce lightweight components, which will help reduce fuel costs and the carbon footprint of, for example, planes, cars, and trucks”.</div> <div><br /></div> <div><strong>Uta Klement </strong>is Professor in Materials Science at Chalmers University of Technology with emphasis on Electron Microscopy and is Head of the Division of Materials and Manufacture at the Department of Industrial and Materials Science. She is also heading the Surface and Microstructure Engineering research group.</div> <div><br /></div> <div><strong>Why is this technology so interesting?</strong></div> <div>“In addition to rapid prototyping through 3D printing, Additive Manufacturing can offer local on-demand spare parts production, customer-specific products, lightweight construction, functional integration, and the opportunity to implement completely new ideas. Product development and market entry can be accelerated significantly while cost reduction and sustainability goals can be achieved at the same time”, says Uta Klement.</div> <div><br /></div> <div><strong>What is the most exciting in the field?</strong></div> <div>“A broader adoption of the additive manufacturing technology depends on the ability to control the entire eco-system, involving pre-printing, printing, and post-printing. This is what we do in CAM2, the Centre for Additive Manufacture - Metal. In addition to a better understanding of the different parts of the process chain, there is currently much focus on quality assurance and the use of inline process monitoring systems together with AI to detect and avoid defects in built components. Also in operando measurements are of much interest to better understand the process and the formed microstructure.</div> <div>Even though additive manufacturing enables the manufacture of parts with a high degree of complexity, internal cooling channels or lattice structures, the surface integrity of the parts is often of inadequate quality, where values for the surface roughness can be much higher than acceptable for many applications. Therefore, surface integrity plays an important role in defining the part's operational performance, which is why post-processing to improve the surface integrity of additively manufactured parts is critical to the introduction of the technology in its broadest sense and requires more attention”, says Uta.</div> <div><br /></div> <div><br /></div> <div><strong>Which materials can be used in Additive Manufacturing / 3D printing?</strong></div> <div>“Due to their ease of use and low melting temperatures, 3D printing began with polymeric materials. Today, additive manufacturing / 3D printing encompasses most types of materials, from polymers to metals, ceramics to living cells”.</div> <div><br /></div> <div><br /></div> <div><strong>Which is the most advanced object constructed using additive manufacturing?</strong></div> <div>“That is of course a matter of opinion. Being able to make custom body parts after trauma surgery can be seen as very important and advanced. But even parts that cannot be manufactured using conventional, i.e., subtractive processes, including material-saving lightweight structures, are very progressive and require a completely new design. For future space exploration, when we travel to Moon and Mars, Additive Manufacturing will be fundamental for producing the vital infrastructure”.</div> <div><br /></div> <div><strong>What are you most looking forward to at this seminar?</strong></div> <div>“I'm looking forward to interesting lectures that give a broad overview of what can already be done with Additive Manufacturing / 3D printing and what challenges we still face”.</div> <div><br /></div> <div><strong>Who should attend to the seminar?</strong></div> <div>“Everyone is welcome, from beginners to experts. I think the seminar offers something for everyone and everyone can learn something new.</div> <div>I hope the participants learn during the seminar that additive manufacturing is very broad and a topic that will keep us busy for the next years to come”, Uta Klement concludes.</div> <div><br /></div> <div><a href="/en/areas-of-advance/materials/Calendar/Pages/Materials-for-Tomorrow-2021.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" /><span style="background-color:initial">P</span><span style="background-color:initial">rogram Materials for Tomorrow 2021 </span></a><br /></div> <span style="background-color:initial"><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Register to the seminar </a></span>Fri, 24 Sep 2021 00:00:00 +0200
