In strong competition, Competence Centre for Catalysis, lead by Chalmers and a new competence center in nuclear technology, which includes researchers from Chalmers, have been selected as two of these.</b></p><div>​<span style="background-color:initial">Competence Centre for Catalysis has the position as Sweden's foremost in its field since it was founded in 1995 and is also an internationally important player. This has not made waiting for the Energy Agency’s decision less nervous for Magnus Skoglundh, Professor at the Department for Chemistry and Chemical Engineering, and Director for the center. He is shining in a contagious joy, when he talks about the news and what it means for the center.</span></div> <div><span style="background-color:initial"><div> </div></span></div> <div>“It has been a fierce competition, and we have been preparing for two years. The funding means that we can start new research areas and projects, and develop our existing areas”, says Magnus Skoglundh. <br /></div> <div> </div> <h2 class="chalmersElement-H2">Start chemical reactions and lowers energy consumption </h2> <div> </div> <div>Catalysis is a phenomenon that allows us to start and affect chemical reactions, with the help of a catalyst. The use of catalytic technology is essential for several of our critical sustainability issues. Therefore, competence and research within this field, is vital if we shall succeed in the transition to sustainable systems for transport, chemical and material production, and energy conversion.<br /><br /></div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/anslag%20kompetenscenter%20Katalys%20och%20kärnenergi/Magnus%20Skoglundh%20200x200.jpg" alt="portrait Magnus Skoglundh " class="chalmersPosition-FloatRight" style="margin:5px" />“The main property of a catalyst is that it lowers the energy barrier required for the reaction to take place. Instead of 300 degrees, it can for example proceed at room temperature, Magnus Skoglundh explains.”<br /><br /></div> <div> </div> <div>In the upcoming period, the center will focus on greenhouse gases to a greater extent than emissions, which they are already strong in. Further, the research on synthesis and production of fossil-free energy carriers will increase. Electrocatalysis is a large part of the center’s work and development of fuel cells, which is an important component for the future fossil-free society. They will also introduce a completely new part - energy efficient and greener chemical industry. The center has many exciting research projects underway. Right now, they are for example working on reducing nitrous oxide emissions, where they are internationally leading.</div> <div> </div> <div><br /></div> <div> </div> <div>One of the center's most important purposes is to train skilled engineers, licentiates, doctors and senior researchers, who can implement what they have learned in the industry. The collaboration with the business community has been ongoing from the start. Today, there are eight member companies in the competence center. At Chalmers, researchers in chemistry and physics have been included and now it will be further broadened with researchers in energy system analysis​.<br /></div> <div> </div> <h2 class="chalmersElement-H2">Premiere for nuclear technology support </h2> <div> </div> <div>Among the Swedish Energy Agency's designated competence centers, there is also research and competence in nuclear technology. It is the first time that the agency supports competence and research in this area. The competence center, which has been named ANItA (Academic-Industrial Nuclear Technology Initiative to Achieve a Future Sustainable Energy Supply) is led by Uppsala University, aims to support the development of small modular nuclear power reactors in Sweden. The project will primarily be focused on current reactor technology, but a significant part will also be about the foundation for future nuclear energy systems.

The monomeric ink is extruded from a print head onto a heated bed triggering the frontal polymerization (FP) reaction. Heat released from the polymerization activates adjacent monomer to further the curing process, thereby forming a self-sustaining propagating reaction wave that polymerizes the printed filament. The stiff polymerized segment of the filament can structurally support the printed part during its fabrication to produce three-dimensional (3D) free form printed structures with excellent fidelity. Fabricated parts exhibit a degree of cure of 99.2% and do not require further post-processing.  The addition of nanoparticles and other reinforcement phases allows access to a range of rheological profiles between low-viscosity liquid and free-standing elastomeric gel – all of which frontally polymerize upon thermal activation. This presentation will summarize the characterization of ink rheology for printing, influence of printing parameters, addition of reinforcing fillers, and the resulting mechanical properties of the printed structures.</span></li></ul></div>Wed, 22 Dec 2021 00:00:00 +0100https://www.chalmers.se/en/departments/physics/news/Pages/Professor-Imre-Pazsit-receives-Wigner-Award.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/Professor-Imre-Pazsit-receives-Wigner-Award.aspxProfessor Imre Pázsit receives Wigner Award<p><b>​Imre Pázsit receives The Eugene P.

Usually, materials in electronics consist of regular, repeating lattices of atoms which makes it very easy for electricity (and heat) to move through the material. But in the material that the researchers examined here, each sheet is slightly rotated, much as if you were carelessly stacking lasagna sheets into a pile. As a result, the heat flow between the layers is hindered, while the heat flow within the layers remains high.</span></div> <div><span style="background-color:initial"><br /></span></div> <div style="font-size:20px"><span style="background-color:initial">Containing and moving heat in different directions</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">This stacking technique provides a material that is extremely good at containing heat and moving it in different directions – an unusual ability at the microscale. </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Paul%20Erhart.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:0px 10px" />“Usually two materials are required: one that conducts heat and one that insulates from heat. This material does both at the same time. On one side of the material the heat is spread unhindered, on the other side it is cool.

This is the focus of Patrik Johansson's research project, which has been granted funding within the Swedish Research Council's Distinguished Professor Programme. The grant of 47.5 million SEK extends over a ten-year period.“The long time span opens up for greater risk-taking and provides the opportunity to work long-term. These are highly important factors for conducting research,” says Patrik Johansson.</b></p><div><strong>Patrik Johansson</strong> is professor at the Department of Physics and one of Sweden's most prominent battery researchers. His focus is on exploring new concepts and solutions for batteries – and that is also what he will do within the context of the Swedish Research Council’s Distinguished Professor Programme.</div> <div><br /></div> <div>The extensive grant means that he, as research leader, can build on already existing projects within his research group, but also explore new possibilities within the framework of what the project's title signals: the next generation of batteries.</div> <div><br /></div> <div>“As a battery researcher it can be easy to just look at the products that exist already today, and thus productize your thinking, especially due to the great interest in society for the ongoing electrification of everything and anything. Your focus turns to short term solutions, in order to help different actors solve whatever problems they are having here and now. That is of course something that has to be done – but as a researcher you also have a responsibility to resist this way of acting and focus on finding concepts that are favourable in a longer time perspective – more of revolution than evolution, says Patrik Johansson.</div> <div><br /></div> <div>“The grant gives me the opportunity to try a lot of fundamentally different things, which you may not always be able to say later on that you have &quot;succeeded with&quot;, but which you in turn learned all the more from and which have been really challenging. And that is successful in itself; discovering the concept space is probably just as important. A special driving force for me personally is to try to get the research group to get far with small and simple ideas – quite challenging today when a lot of research is made large and complicated. The grant is also important to me as a research leader to build our operation, to lead it forward strategically, and to plan for what competencies are needed for a broader and at the same time deeper scope. However, my research <em>itself </em>has not in any way improved by me getting a distinguished professor grant, says Patrik Johansson with a laugh.</div> <div><br /></div> <div style="font-size:20px">Batteries that meet the energy needs of the future</div> <div><br /></div> <div>The battery that is in vogue today is without a doubt the lithium-ion battery, which is found in everything from mobile phones to electric cars and electric ferries. But to meet the mobile and also stationary needs of the future for energy storage in the best way – readily available energy with high quality – large electrochemical energy storage solutions, i.e. batteries, will be needed. Here Patrik Johansson sees that we need to think afresh; perhaps create new types of batteries based on more common metals, such as sodium, calcium or aluminium? Or organic batteries?</div> <div><br /></div> <div>“Today, electrification is being built up in a lot of different sectors and everything is based on lithium-ion batteries. We already see this year that the price of lithium-ion batteries, which has fallen sharply for a long time, is now levelling out. In the long run, it's probably about sustainability. If you can then launch one or more complementary battery technologies that are cheaper, safer, or simply just different – there may be advantages for a battery to for example work at 80 rather than 25 degrees Celsius – there is much to be gained. Today battery researchers in general are not looking in that direction, which my research group will now do. Concept creation is always based on fundamental material physics, but also requires great methodological knowledge and application understanding, says Patrik Johansson.</div> <div><span style="background-color:initial"><br /></span></div> <div style="font-size:20px"><span style="background-color:initial">Conceptually different batteries</span></div> <div><br /></div> <div>Battery research is a field that is developing rapidly. What was in vogue five years ago has already passed in many ways, in terms of exploration of materials, methods and concepts. Likewise, society's needs are changing at a rapid pace – ten years ago there was hardly any talk of electric cars or electric aircraft, today the issue of electrification is dominant in the development of society. So where are we in 2030, to which is the year the Distinguished Professor Programme extends?</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“It is of course very difficult to predict, but what we want for 2030 is something that is conceptually different and not just a refinement of existing technology. Whether that change then may be at the battery, material or functionality level – so be it. What I wish us to have achieved in ten years' time is that we have found two or three new concepts that hold up to a critical examination and at least have the potential to complete the step from research to technology.

This cavity then functions as an optical resonator, a device which offers a tunable system for studying combinations of light and matter known as polaritons.</span><br /></div> <div><br /></div> <div><div><span style="background-color:initial">To see a video from the experiment, where the gold flakes create a self-assembled platform,</span> copy and paste the following link in your web browser: </div> <div><a href="https://static-content.springer.com/esm/art:10.1038/s41586-021-03826-3/MediaObjects/41586_2021_3826_MOESM2_ESM.mp4" style="font-size:10.5pt">https://static-content.springer.com/esm/art%3A10.1038%2Fs41586-021-03826-3/MediaObjects/41586_2021_3826_MOESM2_ESM.mp4</a></div></div> <div> </div> <div><span style="font-size:20px">For more information, contact:</span> </div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><a href="/en/Staff/Pages/Timur-Shegai.aspx">Timur Shegai</a>, Associate Professor, Department of Physics, Chalmers University of Technology, Sweden, +46 31 772 31 23, </span><a href="mailto:timurs@chalmers.se"><span style="background-color:initial">timurs@chalm</span><span style="background-color:initial">ers.se</span></a></div> <div><br /></div> <div><strong>Battulga Munkhbat</strong>, Post Doc, Department of Physics, Chalmers University of Technology, Sweden, +46 73 995 34 79, <a href="mailto:battulga@chalmers.se">battulga@chalmers.se</a></div></div> <div><br /></div> <div>Text: Lisa Gahnertz and Mia Halleröd Palmgren<br />Photo: Anna-Lena Lundqvist (portrait pictures) <span style="background-color:initial">| Illustration: </span><span style="background-color:initial">Yen Strandqvist and </span><span style="background-color:initial">Denis Baranov</span><span style="background-color:initial">​</span></div> <br />​Thu, 02 Dec 2021 07:00:00 +0100https://www.chalmers.se/en/departments/ims/news/Pages/Chalmers-part-of-new-3-billion-sek-research-initiative-on-materials-science-kaw.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Chalmers-part-of-new-3-billion-sek-research-initiative-on-materials-science-kaw.aspxMajor research initiative on materials science<p><b>​The Knut and Alice Wallenberg Foundation is funding just over SEK 3 billion in materials science research for a sustainable world. The purpose is to reduce environmental and climate footprints from the materials we use in our day-to-day lives and industry, which is a necessity to be able to achieve set climate and environmental goals.</b></p>​The Knut and Alice Wallenberg Foundation is now allocating SEK 2.7 billion during the period 2022 – 2033 to a new research program named Wallenberg Initiative Material Science for Sustainability (WISE). The aim of the research program is to create the conditions for a sustainable society by researching next generation of ecofriendly materials and manufacturing processes. This will also facilitate better technology for energy systems of the future, and to combat pollution and toxic emissions.<br /><br />In parallel with this funding, the Wallenberg Wood Science Center, which was established in 2009 with the aim of developing new innovative materials from the Swedish forest, will receive an increased grant of SEK 380 million.<br /><br />“It is incredibly exciting that KAW has chosen to invest in sustainable materials science in this forward-looking way. Chalmers has long conducted outstanding research in this area, and we will be able to contribute to the new initiative with a broad knowledge base. We will be able to take advantage of the new opportunities and strengthen our national collaborations and contribute to strengthening Sweden as an advanced materials development nation together with our strategic partners in the field,” says Anders Palmqvist, vice president for research and professor of materials chemistry, at Chalmers.<br /><div><br /></div> <div><h2 class="chalmersElement-H2">Wallenberg Initiative Material Science for Sustainability</h2> <div>Every year a vast quantity of raw materials is extracted across the world. These are mainly metals, minerals, fossil fuels and biomass. Today most of the extracted materials are non-renewable, placing a heavy burden on the environment, societies, and climate. Global production of materials accounts for a large proportion of the total emissions of greenhouse gases, and the production of metals requires a lot of energy.</div> <div> </div> <div>To meet these challenges, the Wallenberg Initiative Material Science for Sustainability research program focuses on four areas: conversion, storage and distribution of clean energy; circular materials replacing rare, energy-demanding, and hazardous materials; mitigation, cleaning and protection of atmosphere, soil, and water and discovery of materials for novel sustainable technologies.</div> <div> </div> <div>“To meet climate and environmental targets industry needs to transition towards sustainability at a swifter rate. For this reason, the research program will be conducted in collaboration with Swedish industry in the form of industrial PhDs and postdocs, and also via research arenas allowing an exchange of knowledge and problems between academia and private enterprises. Industry acquires knowledge generated by research in materials science, and researchers gain insights into the technological and application challenges faced by companies,” says Sara Mazur, director strategic research at Knut and Alice Wallenberg Foundation, and chair of the program.</div> <div> </div> <div>“We aspire to establish Sweden as a leading nation in this research field. The overall aim is to facilitate sustainable technologies and to educate the leaders of tomorrow in society, industry and academia,” explains Peter Wallenberg Jr.</div> <div><br /></div> <div><h2 class="chalmersElement-H2">Extended grant to Wallenberg Wood Science Center</h2> <div>Wallenberg Wood Science Center was founded in 2009 with the aim of developing new innovative materials from the Swedish forest. Chalmers has participated since the start and can today include researchers from five different departments.</div> <div> </div> <div>“Being part of this multidisciplinary center with a graduate school that has a strong educational program has meant a lot to the researchers. Collaboration across disciplinary boundaries has contributed to new cutting-edge research. At Chalmers, the ability to characterize biomass and developed material have been deepened and new process concepts established. Among other things, we have worked with advanced methods at the ForMAX beam-line at MAXIV in Lund,” says Lisbeth Olsson, professor in industrial biotechnology at Chalmers and co-director at WWSC.</div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Övriga/Lisbeth%20Olsson%20foto%20WWSC_web.jpg" alt="Lisbeth Olsson" class="chalmersPosition-FloatRight" style="margin:10px 15px;width:210px;height:263px" /><br />With the increased grant, the Knut and Alice Wallenberg Foundation has now funded a total of just over SEK 1 billion in research within WWSC. The grant will support research of renewable materials within the program &quot;New materials from trees for a sustainable future&quot;.</div> <div> </div> <div>“It’s fantastic that KAW has decided to continue and expand its funding for the Wallenberg Wood Science Center. It’s incredibly valuable for Chalmers researchers that we can continue the work.

While stellar and planetary dynamos are well studied, our understanding of the dynamo in galaxy clusters is much more limited.

Now the result is here – a technology that with good accuracy can detect disturbances in a nuclear power reactor in operation.</b></p><strong>​</strong><span style="background-color:initial"><strong>Christophe Demazière</strong> and <strong>Paolo Vinai</strong>, both at the Department of Physics, have coordinated the Cortex research project, in which the European Commission has invested 5,1 million euros. Over 70 researchers from various organizations, primarily in Europe, but also from the USA and Japan, have participated in the project during a four-year period, which ended in the summer of 2021.</span><div><br /><div>The project team has consisted of experts from several different research areas: from reactor physics and artificial intelligence, to computational physics and experimental reactor physics. An advisory group of end users has ensured that the research has been carried out in line with the needs of the nuclear power industry and that the benefits of the innovations can be used in the industry.</div> <div><br /></div> <div>The team's collaboration has led to the development and testing of a technology that can detect disturbances in nuclear power reactors.</div> <div><br /></div> <div><span style="font-size:16px">Combines nuclear reactor modelling and artificial intelligence</span><br /></div> <div><br /></div> <div>“By our combined expertise, we have achieved a technology that combines nuclear reactor modelling and artificial intelligence by which you can detect if there is an anomaly in a reactor core. The technology can also detect what kind of disturbance there is and where in the system it is located,” says Christophe Demazière.</div> <div><br /></div> <div>The fundamental of the technology is to teach an artificial intelligence algorithm how a nuclear reactor behaves in the presence of different types of disturbances and their positions. These disturbances lead to fluctuations in the neutron flux, the so-called neutron noise, and they are measured by neutron detectors in the reactor. The algorithm needs to be fed with a lot of data of different types of disturbances and corresponding responses from the reactor.</div> <div><br /></div> <div>“To build such a database, we have developed advanced modelling tools. The algorithm then compares the measurements from the reactor with simulations from these modelling tools. From all these simulations, the algorithm can thus identify in a given measurement if there is a disturbance, of what type it is and where it is located. A reactor core is around three to four meters in diameter and height. Using a few neutron detectors in the core, we can detect where there is a disturbance with a margin of five to ten centimetres. Previous research has shown that this is something that could be done, but no technology has been developed to do so in such a systematic way and to such an extent as in the Cortex project,” says Christophe Demazière.</div> <div><br /></div> <div style="font-size:16px">Keeps track of disturbances</div> <div><br /></div> <div>The technology can, for example, be used during operation to see what is happening in the reactor, the so-called core monitoring. By keeping track of disturbances, you can also better plan for how to handle possible problems when closing a reactor for inspection, maintenance, and fuel reloading.</div> <div><br /></div> <div>Further development of the technology will be required before it can be used on an industrial scale. How or in what form the research project will continue remains to be seen.</div> <div><br /></div> <div>How has it been then, to coordinate such a large project, with so many participants?</div> <div><br /></div> <div>“In the beginning, we spent a lot of time getting to know each other's different research fields, in order to work towards the same goal. We have had close contacts with each othereach other, and everyone has been very motivated in this collaboration. It has been a great job to contribute to the project and see that you do something useful,” says Christophe Demazière.</div> <div><br /></div> <div><a href="https://vimeo.com/578466058" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />See more about how the technology works in a film about the project</a></div> <div><br /></div> <div><strong>Facts about the research project:</strong></div> <div><br /></div> <div>Cortex (CORTEX) stands for &quot;core monitoring techniques and experimental validation and demonstration.&quot; The project aimed to develop innovative methods that can be used to detect and categorize disturbances in commercial nuclear reactors during operation.
