News: Fysik related to Chalmers University of TechnologyTue, 07 Dec 2021 12:46:56 +0100 of the future in focus for Distinguished Professor grant<p><b>​​What will be significant of the batteries of the future? 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. And that we have maintained our curiosity and long-term perspective.”</span></div> <div><br /></div> <div style="font-size:16px">About the Distinguished Professor grant:</div> <div><span style="background-color:initial"><br /></span></div> <div><ul><li><span style="background-color:initial">The purpose of the Swedish Research Council's Distinguished Professor Programme is to create conditions for the most prominent researchers to conduct long-term, innovative research with great potential to achieve scientific breakthroughs.

As a Wallenberg Academy Fellow Chalmers researcher Yasmine Sassa is developing new combinations of materials that display exotic magnetic states, skyrmions, which could play an important role in future technologies for data storage.</b></p>​<span style="background-color:initial">Our electronic revolution is built upon semiconducting silicon. Thanks to its unique properties, electronics and information technologies have developed at an explosive rate, but we are reaching the limit of what today’s materials can do. New hi-tech materials are needed for continued development.</span><div><br /></div> <div>Yasmine Sassa, Assistant Professor at the Department of Physics at Chalmers University of Technology, is developing experimental methods for studying transition metal oxides. These materials have many promising properties for future electronics; when they are combined in a particular manner, they can function as superconductors, or create the right conditions for exotic magnetic states, skyrmions or other topological magnetic states, that could be used for new ways of storing data. If the material is produced as extremely thin films, just a few atoms thick, quantum effects occur that can be used to build quantum computers. </div> <div><br /></div> <div style="font-size:20px">Unexpected magnetic and electronic materials properties<br /></div> <div><br /></div> <div>“My interest in strongly correlated physics started as a Master's student when I took a course about peculiar phenomena in solid-state physics,” says Yasmine Sassa. </div> <div><br /></div> <div>“In this course, we talked about frustrated magnetism and unconventional superconductivity, to name two examples out of many. After that, I had the privilege of extending my knowledge during my Ph.D. and Postdocs. I discovered a fascinating world of new physical properties that cannot be simply explained within classical models. The various correlations give rise to unexpected magnetic and electronic materials properties. If we understand how to control and tune them, we can develop and tailor materials for sustainable technological applications. This is what drives me to pursue research in this field.”</div> <div><br /></div> <div><span style="font-size:20px">Control of quantum effects</span><br /></div> <div><br /></div> <div>In her research, Yasmine Sassa will study the extremely thin films mentioned above, and optimize their chemical composition so that she can study novel topological magnetic states such as skyrmions and control their quantum effects. The long-term objective is to obtain materials that could start a new revolution in the development of hi-tech industries.  </div> <div><br /></div> <div>“I think this research project will push forward our understanding of the skyrmionics field and, in turn, help to develop energy-efficient and sustainable future memory and logic devices. It will give another approach to quantum computing.” says Yasmine Sassa. “The Wallenberg Academic Fellow is a very prestigious grant, and I am honored to receive it!

To be able to do this, different types of ‘resonators’ are often needed – meaning, in this context, an object inside which light bounces around, much like the way sound bounces inside the body of a guitar. Now, researchers working at the Department of Physics at Chalmers University of Technology, have discovered how a previously known form of resonator, made of two parallel mirrors, can be created and controlled in a much simpler way than previously realised.</span><div><br /></div> <div><a href="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Timur%20Shegai-webb_NY.jpg"></a><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Timur%20Shegai-webb_NY.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:135px;height:174px" /><span style="background-color:initial">“</span><span style="background-color:initial">Creating a high quality, stable resonator, such as we have done, is usually complicated and requires many </span><span style="background-color:initial">hours in the laboratory.

The two gold flakes are both positively charged as the aqueous solution covers them with double layers of ions. This causes a repelling electrostatic force, but, due to the simultaneous influence of something called the ‘Casimir effect’, an attracting force is also created, and a stable balance arises, leaving a distance between the flakes of around 150 nanometres. The two nanoflakes orient themsel</span><span style="background-color:initial">ves facing each other, with a cavity formed between them, and they remain stably in this arrangement, for weeks of observations.

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.

The discovery represents an important piece of the puzzle for understanding these materials, and the findings have been published in the highly prestigious journal Science.</b></p><div>​Superconductivity, where an electric current is transported without any losses, holds enormous potential for green technologies. For example, if it could be made to work at high enough temperatures, it could allow for lossless transport of renewable energy over great distances. Investigating this phenomenon is the aim of the research field of high temperature superconductivity. The current record stands at −130 degrees celsius, which might not seem like a high temperature, but it is when compared to standard superconductors which only work below −230 degrees celsius. While standard superconductivity is well understood, several aspects of high temperature superconductivity are still a puzzle to be solved. The newly published research focusses on the least understood property – the so called ‘strange metal’ state, appearing at temperatures higher than those that allow for superconductivity.</div> <div> </div> <div>“This ‘strange metal’ state is aptly named. The materials really behave in a very unusual way, and it is something of a mystery among researchers. Our work now offers a new understanding of the phenomenon. Through novel experiments, we have learned crucial new information about how the strange metal state works” says Floriana Lombardi, Professor at the Quantum Device Physics Laboratory at the Department of Microtechnology and Nanoscience at Chalmers.</div> <h2 class="chalmersElement-H2">Believed to be based on quantum entanglement</h2> <div><img src="/en/departments/mc2/news/PublishingImages/Gruppfoto%20Floriana%20Lombardis%20forskargrupp.jpg" alt="Gruppfoto Floriana Lombardis forskargrupp.jpg" class="chalmersPosition-FloatRight" style="margin:5px;width:340px;height:217px" />The strange metal state got its name because its behavior when conducting electricity is, on the face of it, far too simple. In an ordinary metal, lots of different processes affect the electrical resistance – electrons can collide with the atomic lattice, with impurities, or with themselves, and each process has a different temperature dependence. This means that the resulting total resistance becomes a complicated function of the temperature. In sharp contrast, the resistance for strange metals is a linear function of temperature – meaning a straight line from the lowest attainable temperatures up to where the material melts.</div> <div> </div> <div>“Such a simple behavior begs for a simple explanation based on a powerful principle, and for this type of quantum materials the principle is believed to be quantum entanglement.” says Ulf Gran, Professor at the Division of Subatomic, High-Energy and Plasma Physics at the Department of Physics at Chalmers.</div> <div> </div> <div>“Quantum entanglement is what Einstein called ‘spooky action at a distance’ and represents a way for electrons to interact which has no counterpart in classical physics. To explain the counterintuitive properties of the strange metal state, all particles need to be entangled with each other, leading to a soup of electrons in which individual particles cannot be discerned, and which constitutes a radically novel form of matter.”</div> <h2 class="chalmersElement-H2">Exploring the connection with charge density waves</h2> <div>The key finding of the paper is that the authors discovered what kills the strange metal state. In high temperature superconductors, charge density waves (CDW), which are ripples of electric charge generated by patterns of electrons in the material lattice, occur when the strange metal phase breaks down. To explore this connection, nanoscale samples of the superconducting metal yttrium barium copper oxide were put under strain to suppress the charge density waves. This then led to the re-emergence of the strange metal state. By straining the metal, the researchers were able to thereby expand the strange metal state into the region previously dominated by CDW – making the ‘strange metal’ even stranger </div> <div> </div> “The highest temperatures for the superconducting transition have been observed when the strange metal phase is more pronounced. Understanding this new phase of matter is therefore of utmost importance for being able to construct new materials that exhibit superconductivity at even higher temperatures,” explains Floriana Lombardi. <div><br /></div> <div>The researchers’ work indicates a close connection between the emergence of charge density waves and the breaking of the strange metal state – a potentially vital clue to understand the latter phenomenon, and which might represent one of the most striking evidence of quantum mechanical principles at the macro scale. The results also suggest a promising new avenue of research, using strain control to manipulate quantum materials.  </div> <div> </div> <div><em>The article, <a href="" target="_blank" title="Restored strange metal phase through suppression of charge density waves in underdoped YBa2Cu3O7–δ">‘Restored strange metal phase through suppression of charge density waves in underdoped YBa2Cu3O7–δ’</a> is now available in the leading scientific journal Science.

The study shows how mixing multiple molecules – up to eight at a time – can result in a material that performs as well as the best currently known glass formers. </b></p>​<span style="background-color:initial">A glass, also known as an ‘amorphous solid’, is a material that does not have a long-range ordered structure – it does not form a crystal. Crystalline materials on the other hand, are those with a highly ordered and repeating pattern. The fact that a glass does not contain crystals is what makes it useful.</span><div><br /></div> <div>The materials that we commonly call ‘glass’ in everyday life are mostly silicon dioxide-based, but glass can be formed from many different materials. </div> <div><img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/Cellulosatråd/portratt_christian_muller_320x305px.jpg" alt="Porträttbild Christian Müller " class="chalmersPosition-FloatRight" style="margin:5px" /><span style="background-color:initial">Rese</span><span style="background-color:initial">archers are therefore always interested in finding new ways to encourage different materials to form this amorphous state, which can potentially lead to the development of new types of glass with improved properties and new applications. The new study,<a href="" title="Link to scientific article "> recently published in the scientific journal Science Advances</a>, represents an important step forward in that search.  </span><div><br /></div> <div>“Now, we have suddenly opened up the potential to create new and better glassy materials, by simply mixing many different molecules. Those working with organic molecules know that using mixtures of two or three different molecules can help to form a glass, but few might have expected that the addition of more molecules, and this many, would achieve such superior results,&quot; says Professor Christian Müller at the Department of Chemistry and Chemical Engineering at Chalmers University who led the research team behind the study.    </div> <div><h2 class="chalmersElement-H2">Best result for any glass forming material​</h2></div> <div>A glass is formed when a liquid is cooled down without undergoing crystallisation, a process called vitrification. The use of mixtures of two or three molecules to encourage glass formation is a well-established concept. However, the impact of mixing a multitude of molecules on the ability to form a glass has received little attention. <br /></div> <div><img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/Christian%20Müller%20Molekylmixning%20skapar%20superstabilt%20glas/Sandra%20Hultmark%20320x340.jpg" alt="Porträttbild Sandra Hultmark " class="chalmersPosition-FloatRight" style="margin:5px" /><br />The researchers experimented with a mixture of up to eight different perylene molecules which, individually, have a high fragility – a property related to how easy it is for a material to form a glass. But mixing many molecules resulted in a substantial decrease in fragility, and a very strong glass former with ultralow fragility was formed. </div> <br /></div> <div>“The fragility of the glass we created in the study is very low, representing the best glass-forming ability that has been measured not only for any organic material but also polymers and inorganic materials such as bulk metallic glasses. The results are even superior to the glass forming ability of ordinary window glass, one of the best glass formers that we know of” says Sandra Hultmark, doctoral student at the Department of Chemistry and Chemical Engineering and lead author of the study​</div> <h2 class="chalmersElement-H2">Extending product life and saving resources</h2> <div>Important applications for more stable organic glasses are display technologies such as OLED screens and renewable energy technologies such as organic solar cells. <br /><br /></div> <div><div>“OLEDs are constructed with glassy layers of light-emitting organic molecules. If these were more stable it may improve the durability of an OLED and ultimately the display,” Sandra Hultmark explains. </div> <div><br />Another application that may benefit from more stable glasses are pharmaceuticals. Amorphous drugs dissolve more quickly, which aids rapid uptake of the active ingredient upon ingestion. Hence, many pharmaceuticals make use of glass-forming drug formations. For pharmaceuticals it is vital that the glassy material does not crystallise over time. The more stable the glassy drug, the longer the shelf life of the medicine. <br /><br /></div> <div>“With more stable glasses or new glass forming materials, we could extend the lifespan of a large number of products, offering savings in terms of both resources and economy,” says Christian Müller.</div></div> <div><br /></div> <div></div> <div><br /></div> <h3 class="chalmersElement-H3">More about the research​</h3> <div><br /></div> <div><div><ul><li>The scientific article <a href="" title="Link to scientific article ">“Vitrification of octonary perylene mixtures with ultralow fragility”</a> has been published in the scientific journal Science Advances and is written by Sandra Hultmark, Alex Cravcenco, Khuschbu Khushwaha, Suman Mallick, Paul Erhardt, Karl Börjesson and Christian Müller.
