News: Centre KCK related to Chalmers University of TechnologyWed, 17 Aug 2022 09:42:58 +0200​Time to inaugurate all-wise computer resource<p><b>​Alvis is an old Nordic name meaning &quot;all-wise&quot;. An appropriate name, one might think, for a computer resource dedicated to research in artificial intelligence and machine learning. The first phase of Alvis has been used at Chalmers and by Swedish researchers for a year and a half, but now the computer system is fully developed and ready to solve more and larger research tasks.​</b></p><br /><div><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/300x454_Alvis_infrastructure_1.png" alt="A computer rack" class="chalmersPosition-FloatRight" style="margin:10px;width:270px;height:406px" />Alvis is a national computer resource within the <strong><a href="">Swedish National Infrastructure for Computing, SN​IC,</a></strong> and started on a small scale in the autumn of 2020, when the first version began being used by Swedish researchers. Since then, a lot has happened behind the scenes, both in terms of use and expansion, and now it's time for Chalmers to give Swedish research in AI and machine learning access to the full-scale expanded resource. The digital inauguration will take place on <span style="font-weight:normal"><a href="/en/areas-of-advance/ict/calendar/Pages/Alvis-inauguration-phase-2.aspx">February 25, 202</a>2.</span></div> <div><br /></div> <div><b>What can Alvis contribute to, then? </b>The purpose is twofold. On the one hand, one addresses the target group who research and develop methods in machine learning, and on the other hand, the target group who use machine learning to solve research problems in basically any field. Anyone who needs to improve their mathematical calculations and models can take advantage of Alvis' services through SNIC's application system – regardless of the research field.</div> <div><span style="background-color:initial">&quot;Simply put, Alvis works with pattern recognition, according to the same principle that your mobile uses to recognize your face. What you do, is present very large amounts of data to Alvis and let the system work. The task for the machines is to react to patterns - long before a human eye can do so,&quot; says <b>Mikael Öhman</b>, system manager at Chalmers e-commons.</span><br /></div> <div><br /></div> <h3 class="chalmersElement-H3">How can Alvis help Swedish research?</h3> <div><b>Thomas Svedberg</b> is project manager for the construction of Alvis:</div> <div>&quot;I would say that there are two parts to that answer. We have researchers who are already doing machine learning, and they get a powerful resource that helps them analyse large complex problems.</div> <div>But we also have those who are curious about machine learning and who want to know more about how they can work with it within their field. It is perhaps for them that we can make the biggest difference when we now can offer quick access to a system that allows them to learn more and build up their knowledge.&quot;</div> <div><br /></div> <div>The official inauguration of Alvis takes place on February 25.

The chemical reactions in catalysis occur in a comparable way. Millions of individual particles are involved, and it is currently very difficult to track and determine the roles of each specific one – how effective they are, how much each has contributed to the reaction. <span style="background-color:initial"> </span></div> <div><span style="background-color:initial"><br /></span></div> <div>To better understand the catalytic process, it is necessary to investigate it at the level of individual nanoparticles.

In each tunnel the researchers placed a single gold nanoparticle. Though they are of similar size, each nanoparticle has varied catalytic qualities – some are highly effective, others decidedly less optimal.

In a catalyst, metal nanoparticles are often some of the most crucial active ingredients, because the chemical reactions take place on their surface. The best-known example is probably the three-way catalytic converter found in cars, which mitigates harmful emissions. Catalysis is also widely used in industry at large scale and has a key role to play in new sustainable energy technologies, such as fuel cells. To develop catalysts for the future, new and effective materials are needed.

To identify the efficiency of each particle in the catalytic process, the researchers isolated individual gold nanoparticles in separate nanotunnels. They then sent in two kinds of molecules that react with each other on the particles’ surfaces. One molecule (fluorescein) is fluorescent and when it meets its partner molecule (borohydride) the light emission stops upon reaction between the two.

Eager researchers watched as the precious, long-awaited packages were loosened. There were worries that the lift might not even be able to cope with the weight, but it managed. Almost a year of assembly, installation and adjustment followed, and now the microscope, which weighs five tonnes, is in place at Chalmers Material Analysis Laboratory (CMAL). It sits in a disturbance-protected room with adapted temperature and air conditions and is available to researchers in both the academy and industry.<br /><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/IMG_1755EvaOlsson_01_350x.jpg" class="chalmersPosition-FloatRight" alt="" style="background-color:initial" />“It is great that we can now start all the experiments we have planned – we have a long wish list. When we can study and control different materials, right down to the atomic level, a whole universe of possibilities opens. For example, we can produce more healthy foods, smarter solar cells and more environmentally-friendly textiles and paper,” says Physics Professor Eva Olsson, who is responsible for the microscope project at Chalmers.<br /><br /></div> <div>She has worked hard for Chalmers to be able to buy a total of three advanced electron microscopes that open up new possibilities in soft microscopy. What is now being inaugurated is a transmission electron microscope (TEM) made in Japan by JEOL, by far the standout of the three. The total investment is around 66 million Swedish kronor, of which the Knut and Alice Wallenberg Foundation has contributed half.</div> <div>What is unique about the new, large TEM is its very high spatial and energy resolution.

Professor of physics Aleksandar Matic, and researcher Carmen Cavallo, published an article on how they managed to produce a cathode material for lithium sulphur batteries, based on graphene, allowing for higher energy content and longer lifespan. They investigated the structure of the cathode material using the new microscope. Meanwhile, Eva Olsson's research group has also developed the knowledge about how to make solar cell nanowires more efficient.

The results have been published in Nature Communications. The methods can be used to improve many different types of catalysts.​</b></p><div>Catalysts are materials which cause or accelerate chemical reactions. For most of us, our first thought is probably of catalytic converters in cars, but catalysts are used in a number of areas of society – it has been estimated that catalysts are used in the manufacture of more than 90 percent of all chemicals and fuels. No matter how they are used, catalysts operate through complex atomic processes. In the new study from Chalmers, physics researchers combined two approaches to add a new piece to the catalyst puzzle. They used advanced, high-resolution electron microscopy and new types of computer simulations.</div> <div><br /></div> <div>&quot;It is fantastic that we have managed to stretch the limits and achieve such precision with electron microscopy. We can see exactly where and how the atoms are arranged in the structure. By having picometre precision – that is, a level of precision down to one hundredths of an atom’s diameter – we can eventually improve the material properties and thus the catalytic performance,&quot; says Torben Nilsson Pingel, researcher at the Department of Physics at Chalmers and one of the authors of the scientific article.</div> <div><br /></div> <div>Through this work, he and his colleagues have managed to show that picometre-level changes in atomic spacing in metallic nanoparticles affect catalytic activity. The researchers looked at nanoparticles of platinum using sophisticated electron microscopes in the Chalmers Material Analysis Laboratory. With method development by ​Andrew Yankovich, the researchers have been able to improve the accuracy and can now even reach sub-picometre precision. Their results now have broad implications.</div> <div><br /></div> <div>&quot;Our methods are not limited to specific materials but instead based on general principles that can be applied to different catalytic systems. As we can design the materials better, we can get both more energy-efficient catalysts and a cleaner environment,&quot; says Eva Olsson, Professor at the Department of Physics at Chalmers.</div> <div><br /></div> <div>The work was carried out within the framework of the Competence Centre for Catalysis at Chalmers. In order to study how small changes in atomic spacing really affect the catalytic process, Mikkel Jørgensen and Henrik Grönbeck, PhD student and Professor at the Department of Physics respectively, performed advanced computer simulations at the national computing centre, located at Chalmers.

They will produce a new research methodology that, on atomistic level, will enable customisation of the next generation of catalysts, which may become the cornerstones of future energy systems.</b></p>​ <div>A catalyst is a substance that increases the rate of a chemical reaction, without becoming consumed. The project addresses heterogeneous catalysis, which means that when molecules come in contact with the catalyst's surface, they are affected by the surface's electrons and converted into new molecules. Catalysis both occurs in nature and is used industrially on a large scale. Over 90 percent of all chemicals are produced using catalysts, and they are, for example, needed to produce renewable fuels. New knowledge on catalysts will enable harmful processes to be replaced by environmentally friendly alternatives. </div> <p><br />- &quot;Catalysis constitutes such a major part of production that development of catalysts is entirely decisive for the future. Without progress, we will not be able to achieve an energy-efficient society,&quot; says Magnus Skoglundh. </p> <p><br /><img class="chalmersPosition-FloatRight" alt="Max IV synchrotron facility in Lund" src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/2s5d97491_300.jpg" style="height:220px;width:338px;margin:20px 10px" />The research team, which consists of researchers from Chalmers (in addition to Magnus Skoglundh and Henrik Grönbeck also Per-Anders Carlsson and Anders Hellman), Lund University and the Max IV synchrotron facility in Lund, will produce a method that in the future may become the leading way to design catalysts. With funding from the KAW Foundation for the project Atomistic Design of Catalysts, they will, amongst other things, take on the challenging task of creating a short cut in the production of methanol directly from methane. Methanol is currently produced through several catalytic steps, but the new method is expected to be effective to the extent that methanol could be produced in a single catalytic reaction, which would increase profitability in production and reinforce methanol's position as alternative fuel.  </p> <div><br />- &quot;In the world of catalysis, being able to produce methanol through direct partial oxidation would be something of a dream reaction. In this process, methane becomes methanol by adding oxygen, something which is not yet possible to do industrially,&quot; says Magnus Skoglundh. </div> <div><br />The primary aim of the project, however, is to develop a new methodology that can be used for several different types of reactions. Direct partial oxidation of methane to methanol is one example of a very difficult key reaction the team hopes to achieve. </div> <div><br />In order to succeed with this reaction and many others, researchers are going down to atom level. The surface on which the catalytic reactions take place must be adjusted so that the atoms are optimally placed for the catalytic reaction. </div> <div><br />- &quot;It is a matter of how the electrons move. We calculate what is happening during the reaction and how the atoms should be arranged to achieve better results. The computational methods have become so powerful that it is now possible to predict how the catalysts will function before the material is even produced. It has not been possible to do this before now. This is one of the most fascinating scientific advances that have been in made in the past twenty years,&quot; says Henrik Grönbeck. </div> <div><br />The researchers say that primarily two scientific advances have made the current project possible. The technical and theoretical development during recent years has resulted in the possibility to conduct quantum mechanical calculations on how electrons behave when molecules come into contact with different surfaces, at the same time that the thoroughly modern Max IV synchrotron facility will be ready for use. From the point of view of the project, Max IV will make it possible, with synchrotron light, to measure what is happening on atom level in a catalytic reaction, which has not been possible previously. </div> <div><br />- &quot;We can study a catalytic reaction in the Max IV laboratory and obtain a large amount of data. We then use quantum mechanics and a great deal of computational resources to interpret the data to give it a physical reality and compute what will happen if we modify the structure of the surface,&quot; says Magnus Skoglundh. </div> <div><br />It is also possible to follow the reaction while it is in progress. Some catalysts are most effective at certain conditions, which will be possible to measure with synchrotron light. It will also be possible to take the optimal conditions into account in the calculations.</div> <div><br />- &quot;In order to make progress in catalysis research, we have to know what happens when the reaction is happening. This has been very difficult thus far,&quot; says Henrik Grönbeck.</div> <div><br />The grant from KAW will enable additional new doctoral students to be hired to work on developing the method and explore the different catalytic reactions on a level that has not previously been possible.</div> <div><br />- &quot;The funding constitutes a substantial contribution to catalysis research at Chalmers and the Competence Centre for Catalysis (KCK). With a grant of this size, we can take large steps forward,&quot; says Henrik Grönbeck.</div> <div> </div> <div> </div> <div>The Knut and Alice Wallenberg Foundation is Sweden's largest private financier of research. In October, the foundation will allocate 25 grants for research projects deemed to maintain a high international standard and to have the potential to lead to future scientific breakthroughs. The grants will go towards basic research in medicine, technology and science. </div> <div> </div> <div><strong>Text: </strong>Mats Tiborn</div> <div><strong>Photo: </strong>Mats Tiborn and Perry Nordeng</div> <div> </div>Fri, 09 Oct 2015 00:00:00 +0200
