The event is coordinated from Chalmers with Professor Göran Wendin at the forefront. Now he is chasing top Swedish students for the conference.</b></p><img src="/SiteCollectionImages/Institutioner/MC2/News/GoranWendin_171101_01_350x305.jpg" alt="Picture of Göran Wendin" class="chalmersPosition-FloatRight" style="margin:5px" />Göran Wendin, to the right, is one of the driving forces within the Wallenberg Centre for Quantum Technology (WACQT), which is led by Chalmers and aims to build a Swedish quantum computer within twelve years. At the moment, however, he is fully busy with the QFA2020 management.<br />&quot;It is an extensive job with a lot of work, but also a lot of fun,&quot; he says in a pause.<br /><br />The assignment comes directly from the German research institute VDI Technologiezentrum [VDITZ] in Düsseldorf, which is the headquarters of the EU's research flagship on quantum technology, worth one billion euros, launched in autumn 2018.<br /><br />The idea of ​​QFA2020 is to offer European top students in the field of quantum technology an opportunity to gain new knowledge and new contacts in order to develop future commercial applications of the technology.<br />Similar events have been held four times before, then at the national level in Germany and France. Now, QFA is opening up and turning it into a major European education conference with participants from 30 countries.<br />&quot;One of the aims is to raise the understanding of quantum technology as a matter for Europe as a whole. We want to help create a sustainable network of young researchers,&quot; says Göran Wendin.<br /><br />Each participating country selects two students during the late summer who can travel to Germany completely free of charge in November. Travel, accommodation and living are fully reimbursed.<br /><br />QFA2020 will take place in Berlin. However, Göran Wendin points out that the organizers are closely following the development of the corona pandemic, and that all safety procedures will be followed.<br />&quot;All participants will receive detailed information in good time about any changes,&quot; he says.<br /><br />The application is open until 24 July for all interested students at the bachelor's or master's level with basic knowledge in quantum mechanics. In Sweden, the winners will be presented at a digital workshop at Chalmers in mid-September, where all applicants will present their ideas.<br /><br />The conference week in Berlin in November has a packed content. It will include study visits to companies and research laboratories, lectures, meetings with researchers, politicians and entrepreneurs, workshops and even cultural activities.<br />&quot;We can promise an exciting and exclusive week in Berlin,&quot; concludes Göran Wendin.<br /><br />Text: Michael Nystås<br />Photo: Johan Bodell<br /><br /><strong>Contact:</strong><br />Göran Wendin, Professor, Quantum Technology Laboratory, Wallenberg Centre for Quantum Technology (WACQT), Department of Microtechnology and Nanoscience <span>–<span style="display:inline-block"></span></span> MC2, Chalmers,<br /><br /><div><span><strong>Read more about Quantum Future Academy 2020 (QFA2020) &gt;&gt;&gt;</strong><br /><a href="/en/centres/wacqt/qfa2020"></a> and also<br /><a href=""></a> <br /><br /><strong><a href="/en/centres/wacqt">Read more about Wallenberg Centre for Quantum Technology (WACQT)</a> &gt;&gt;&gt;</strong><br /><br /><a href="">Läs mer om Read more about the EU flagship in quantum technology </a>&gt;&gt;&gt;<span style="display:inline-block"></span></span><br /></div>Fri, 03 Jul 2020 09:00:00 +0200's-disease-protein-damages-cell-membranes-.aspx's-disease-protein-damages-cell-membranes-.aspxNew method shows how Parkinson&#39;s protein damages cells<p><b>​In sufferers of Parkinson&#39;s disease, clumps of α-synuclein (alpha-synuclein), sometimes known as the ‘Parkinson’s protein’, are found in the brain. These destroy cell membranes, eventually resulting in cell death. Now, a new method developed at Chalmers University of Technology, Sweden, reveals how the composition of cell membranes seems to be a decisive factor for how small quantities of α-synuclein cause damage.</b></p><p class="chalmersElement-P">​<span>Parkinson's disease is an incurable condition in which neurons, the brain's nerve cells, gradually break down and brain functions become disrupted. Symptoms can include involuntary shaking of the body, and the disease can cause great suffering. To develop drugs to slow down or stop the disease, researchers try to understand the molecular mechanisms behind how α-synuclein contributes to the degeneration of neurons.</span></p> <p class="chalmersElement-P">It is known that mitochondria, the energy-producing compartments in cells, are damaged in Parkinson's disease, possibly due to ‘amyloids’ of α-synuclein. Amyloids are clumps of proteins arranged into long fibres with a well-ordered core structure, and their formation underlies many neurodegenerative disorders. Amyloids or even smaller clumps of α-synuclein may bind to and destroy mitochondrial membranes, but the precise mechanisms are still unknown.</p> <h2 class="chalmersElement-H2">New method reveals structural damage to mitrochondrial membranes​</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The new study, recently published in the journal <em>PNAS</em>, focuses on two different types of membrane-like vesicles. One of them is made of lipids that are often found in synaptic vesicles, the other contained lipids related to mitochondrial membranes. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><span style="background-color:initial">The researchers found that the Parkinson’s protein would bind to both vesicle types, but only caused structural changes to the mitochondrial-like vesicles, which deformed asymmetrically and leaked their contents.</span><br /></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> “Now we have developed a method which is sensitive enough to observe how α-synuclein interacts with individual model vesicles, which are ‘capsules’ of lipids that can be used as mimics of the membranes found in cells. In our study, we observed that α-synuclein binds to – and destroys – mitochondrial-like membranes, but there was no destruction of the membranes of synaptic-like vesicles. The damage occurs at very low, nanomolar concentration, where the protein is only present as monomers – non-aggregated proteins. Such low protein concentration has been hard to study before but the reactions we have detected now could be a crucial step in the course of the disease,” says Pernilla Wittung-Stafshede, Professor of Chemical Biology at the Department of Biology and Biological Engineering. </p> <h2 class="chalmersElement-H2">&quot;Dramatic ​differences in how the protein affects membranes&quot;</h2> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The new method from the researchers at Chalmers University of Technology makes it possible to study tiny quantities of biological molecules without using fluorescent markers. This is a great advantage when tracking natural reactions, since the markers often affect the reactions you want to observe, especially when working with small proteins such as α-synuclein.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> “The chemical differences between the two lipids used are very small, but still we observed dramatic differences in how α-synuclein affected the different vesicles,” says Pernilla Wittung-Stafshede.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“We believe that lipid chemistry is not the only determining factor, but also that there are macroscopic differences between the two membranes – such as the dynamics and interactions between the lipids. No one has really looked closely at what happens to the membrane itself when α-synuclein binds to it, and never at these low concentrations.” </p> <p></p> <h2 class="chalmersElement-H2">Next step: Investigate proteins with mutations and cellular membranes</h2> <p></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The next step for the researchers is to investigate variants of the α-synuclein protein with mutations associated with Parkinson's disease, and to investigate lipid vesicles which are more similar to cellular membranes.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"> “We also want to perform quantitative analyses to understand, at a mechanistic level, how individual proteins gathering on the surface of the membrane can cause damage” says Fredrik Höök, Professor at the Department of Physics, who was also involved in the research.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“Our vision is to further refine the method so that we can study not only individual, small – 100 nanometres – lipid vesicles, but also track each protein one by one, even though they are only 1-2 nanometres in size. That would help us reveal how small variations in properties of lipid membranes contribute to such a different response to protein binding as we now observed.”</p> <p class="chalmersElement-P"><strong>Text: </strong>Susanne Nilsson Lindh and Joshua Worth<br /><strong>Illustration:</strong> Fredrik Höök</p> <p class="chalmersElement-P"><br /></p> <div> </div> <div><strong>More information on the method</strong></div> <div> </div> <div><ul><li>Vesicle membranes were observed by measuring light scattering and fluorescence from vesicles which were bound to a surface – and monitoring the changes when low concentrations of α-synuclein were added.</li> <li>Using high spatiotemporal resolution, protein binding and the resulting consequences on the structure of the vesicles, could be followed in real time.

In 2016, the Chalmers fence was launched during the annual Gothenburg Horse Show. Chalmers’ collaboration with the show has since then been about bringing theory and practice together, to decode the optimal jumping kinematics, and contribute with more sustainable horses and training methods.</b></p><div>Chalmers investment in equestrian sports technology has proven to be successful. The world of sport is always looking for new ideas and serves well as a testing arena for developing new technical solutions and materials. This research field is also giving Chalmers students the opportunity to combine leisure interests with studies.</div> <div> </div> <div><br /></div> <div> </div> <div>“The Chalmers fence is something the students work with in addition to their own studies, it is an opportunity to participate in a project that really makes a mark outside campus,” says Anna Karlsson-Bengtsson, Vice President of Education and Lifelong Learning at Chalmers University of Technology.</div> <div> </div> <h2 class="chalmersElement-H2">​​​<span>From idea to crowded arena</span></h2> <div> </div> <div>The Chalmers fence is a &quot;smart showjumping fence&quot; and every year a new technical solution is created to measure another kinematic aspect of the jumps. The results are presented to the large audience in Scandinavium on the jumbotron during the ongoing competition at the Gothenburg Horse Show.</div> <div> </div> <div><br /></div> <div> </div> <div><img src="/SiteCollectionImages/20200101-20200701/Chalmershindret%202016-2020/MagnusKarlsteen_textbild200x250.jpg" class="chalmersPosition-FloatLeft" alt="magnus karlsteen" style="margin:5px;width:150px;height:186px" />“I really want to point out that this project is the result of many enthusiasts' ideas and struggles. Many people at Chalmers have been involved over the years, not least horse-interested students,” says Magnus Karlsteen, adding that it is not only equestrian people involved in the projects. Many do it for the technical challenge and the community around it, says Magnus Karlsteen, who is responsible for the Chalmers Fence and Chalmers Equestrian sports projects.</div> <div> </div> <div><br /></div> <div> </div> <div>Magnus Karlsteen went to riding school for one summer as a 6-year-old, but he &quot;has hardly ever seen a horse since then&quot;. Nevertheless, Chalmers’ research into equestrian sports has attracted considerable attention in the equestrian world, which is much larger than most people can imagine. According to the Swedish Equestrian Federation, half a million Swedes are involved in the sport and it is Sweden's third largest youth sport (for 7–25-year olds). There is a significant equestrian sports industry with everything from suppliers of horse feed and veterinarians to product developers and trainers.</div> <div><br /></div> <div> </div> <div>Chalmers often organises public seminars, where different stakeholders are invited to share the latest in different research areas. When the first meeting regarding equestrian sports was organised in 2012, it turned out that the demand for research within the field was enormous.</div> <div><br /></div> <div> </div> <div>“At a certain equestrian technology meeting we received several hundred interested people. The interest was almost as great as when the Nobel laureates visits campus,” says Magnus Karlsteen.</div> <div><br /></div> <div> </div> <div>A few years later, in 2015, Chalmers met representatives from Gothenburg Horse Show for the first time and the Chalmers fence, which was originally initiated by the former Vice President Maria Knutson-Wedel, began to grow from idea to reality.</div> <div> </div> <div><br /></div> <div> </div> <div>“The collaboration with Chalmers is part of Gothenburg Horse Show's work to support development. Equestrian sport has been given new scientific information which supports our work on horse training and competition”, says Tomas Torgersen, director for the Gothenburg Horse Show.<span style="background-color:initial"> </span></div> <div> </div> <h2 class="chalmersElement-H2">Opportunity to combine interests with studies</h2> <div> </div> <div>Although the investment has only been going for five years, there are already examples of horse-interested Chalmers students who have gained interest in the engineering profession after seeing the Chalmers fence and visiting Chalmers’ booth during the competition in Scandinavium.</div> <div> </div> <div><br /></div> <div> </div> <div>Chalmers student Anna Skötte, project manager for the fence group 2020, is interested in both horses and technology and thinks that the Chalmers fence shows how well it works to combine these two interests.<img src="/SiteCollectionImages/20200101-20200701/Chalmershindret%202016-2020/Annaskotte_textbild_hinder.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:200px;height:196px" /><br /><br /></div> <div> </div> <div><span style="background-color:initial">“</span><span style="background-color:initial">The days we spent in Scandinavium were extremely exciting, even though they also were very busy. The most fun thing was that everyone involved and even the audience experienced the fence measurements as interesting and successful! Also, the fact that I got to know so many different people both from Chalmers and the outside world has been very valuable,” says Anna Skötte.</span></div> <div> </div> <h2 class="chalmersElement-H2">​&quot;We forgot that horses have tails”</h2> <div> </div> <div>Technical problems and time issues are a part of the everyday life of an engineer, something that the Chalmers students who have been involved in the Chalmers fence have gained practical experience of. </div> <div><br /></div> <div>Magnus Karlsteen talks about one of the most memorable incidents over the years. During a test run a few days before the show, the participating horse had an unusually long tail. The fence had been jumped before and everything had worked well, but now the technology caught the lowest point of the tail, instead of the hooves, as the measuring point over the fence. In the computer, it looked like every bar was falling down, when in reality it was only hairs from the tail that rubbed the bars.</div> <div><br /></div> <div> </div> <div>“It was eventually solved by having students manually reviewing each point of the kinematics before the results were posted on the jumbotron in the arena. It is an example of what a good training in problem-solving the project gives the students – they get an invaluable experience of real working life,” says Magnus Karlsteen.</div> <div> </div> <h2 class="chalmersElement-H2">Old truths questioned through new knowledge</h2> <div> </div> <div>The Chalmers fence has questioned a long-lived myth in the world of equestrian sport. The old truth says that the horse's takeoff point  is as far ahead of the fence as the fence is high. But when the students' results of the Chalmers fence in 2017 were analysed by Chalmers researcher Kristina Wärmefjord, it was confirmed that the horses jump off considerably further away than that. There is even a formula for this, which reads &quot;1.3x obstacle height + 0.2&quot;. The measurements showed that on a 1.50 fence, the horse's hooves are on average 2.15 meters from the fence in the take-off.</div> <div> </div> <div><br /></div> <div> </div> <div><img src="/SiteCollectionImages/20200101-20200701/Chalmershindret%202016-2020/Chalmershindret_200x250px.jpg" alt="showjumping" class="chalmersPosition-FloatLeft" style="margin:5px" />The results from Gothenburg Horse Show have over the years also confirmed knowledge that previously was mostly based on the riders' gut feeling, for example that more experienced horses and riders manage to maintain a more even rhythm and speed – before, over and after the fence. In classes with young riders or young horses, the numbers were much more varied than in the world elite jumping classes.</div> <div> </div> <div>Worldwide interest </div> <div> </div> <div><br /></div> <div> </div> <div>Chalmers has collaborations with several stakeholders both in Sweden and abroad regarding equestrian sport technology. There are collaborations with the Swedish breeding association SWB, and research applications are in progress together with the International equestrian committee, Fédération Équestre Internationale (FEI). There is also a collaboration with Sahlgrenska University Hospital and with the Swedish University of Agricultural Sciences (SLU). During the European Championships in Gothenburg 2017, Chalmers students also participated in the production of obstacles for the competitions in driving, and through a design competition Chalmers students developed no less than four of the jump fences at the Ullevi stadium. There are also examples of Chalmers projects in trotting and horse racing.</div> <div> </div> <div><br /></div> <div> </div> <div>A collaboration with the Swedish School of Textiles in Borås has resulted in development of the possibility to measure ECG, heart rate and breathing with smart textiles through the horses’ fur – the list of impacts in different areas can be long. Chalmers’ equestrian technology has established contacts within equine research in Australia. Among other things, several students were invited to present their horse racing project in the Australian city of Wagga Wagga in 2018.</div> <div> </div> <div><br /></div> <div> </div> <div>“The students are given a unique opportunity to create a network – internally at Chalmers, in the corporate world, in the horse sector and in various research areas around the world. We are constantly contacted by new stakeholders,” says Magnus Karlsteen.</div> <div> </div> <div><br /></div> <div> </div> <p class="chalmersElement-P">Ireland is another great horse nation that has shown interest in Chalmers’ equestrian technology. During Gothenburg Horse Show this year, the fence group was contacted by the head of the Ireland national team.

The phones in our pockets have cameras comparable to a DSLR – technological masterpieces with millions of pixels of resolution.

These technologies have developed extremely rapidly in recent years, due mainly to smaller and more effective circuit components.<br /></div> <div><br /></div> <div><div>However, camera lenses themselves have not changed as much. The majority of today's lenses are based on the same physical principles, and include the same basic limitations, as the first prototypes invented in the sixteenth century.

Unlike today's lithium-ion batteries, solid-state batteries have a solid electrolyte and therefore contain no environmentally harmful or flammable liquids.</div> <div>Simply put, a solid-state battery can be likened to a dry sandwich. A layer of the metal lithium acts as a slice of bread, and a ceramic substance is laid on top like a filling. This hard substance is the solid electrolyte of the battery, which transports lithium ions between the electrodes of the battery. But the ‘sandwich’ is so dry, it is difficult to keep it together – and there are also problems caused by the compatibility between the ‘bread’ and the ‘topping’. Many researchers around the world are working to develop suitable resolutions to address this problem.</div> <div><br /></div> <div>The material which the researchers in Gothenburg and Xi'an are now working with is a soft, spreadable, ‘butter-like’ substance, made of nanoparticles of the ceramic electrolyte, LAGP, mixed with an ionic liquid. The liquid encapsulates the LAGP particles and makes the interlayer soft and protective. The material, which has a similar texture to butter from the fridge, fills several functions and can be spread easily.</div> <div>Although the potential of solid-state batteries is very well known, there is as yet no established way of making them sufficiently stable, especially at high current densities, when a lot of energy is extracted from a battery cell very quickly, that is at fast charge or discharge.

He did a great job on studying kinetics of nanoparticle catalysis from first principles. His thesis is well written, there is a coherent flow of information throughout the whole work. The thesis is also written in a very pedagogical way, so that a person outside of the catalysis and physical chemistry field could follow and understand both basic and advanced concepts. Moreover, Mikkel's work has generated a considerable impact due to the substantial amount of high-profile peer-reviewed publications on which the thesis is based. We were particularly impressed by Mikkel's outstanding contributions to these publications (the thesis is based on ten publications, out of which Mikkel is the first author of nine. Eight of the articles are written by only him and his supervisor). Altogether, this made us to choose Mikkel for the best PhD thesis award in 2019.

Combining this with standard overhead film, they created a face visor approved for use in healthcare. </span><div><br /><div>Jonsson contacted 3Dteamet, the 3D printing team in the Physics Building – twelve students with the ability to put them into rapid production. Edward Hadziavdic and Marcus Toftås got their group in the Physics laboratory going, with the full support of Lars Hellberg, who is responsible for the Physics Department’s experimental laboratory where much of the equipment is located. Meanwhile Jonsson adjusted the design, making it more robust and more suitable for manufacture and added a support so that it would fit staff with different head sizes. 3Dteamet rewrote the code that everyone is now using.</div> <div><br /></div> <div>On Sunday 29 March Chalmers made an initial test shipment of 230 visors to hospitals in Western Sweden.</div> <div><br /></div> <div>“The region got in touch on Monday and asked us to continue with production of the approved design. We don’t have the capacity to manufacture 100,000, which is what they really need, according to Region Västra Götaland (VGR),” says Hadziavdic, who is now VGR’s contact for the visors and who is coordinating all the new volunteers that offer their services to help tackle the lack of visors in the short term. </div> <div><br /></div> <div>VGR uploaded a direct link to the Chalmers’ team on its website, for anyone who was interested in contributing via their own production. Every day has brought streams of new producers. Toftås rapidly became the ‘production manager’ and is handling the logistics from private producers, other workshops at Chalmers and large industrial companies. </div> <div><br /></div> <div>“Right now we are gathering everything in our laboratory in the Physics Building which is where VGR brings trucks to make collections several times a week,” says Toftås.</div> <div><br /></div> <div>Now on the ninth delivery day, VGR has received a total of 2,500 visors from Chalmers, and just as many are in progress or already completed and awaiting collection.</div> <div><br /></div> <div>“We are incredibly grateful for all the hard work that all the volunteers have put in.

In addition to visors, Chalmers has sent lab coats and produced hand sanitiser, mainly from the Chemistry Department. So far several hundred litres of hand sanitiser have been dispatched. </div> <div><br /></div> <div>“A dialogue in currently under way to find out how we can help with other items. I am convinced we can do a lot more than visors,” says Jan Froitzheim, Associate Professor of Chemistry, who is coordinating Sjukvårdshjälpen from Chalmers.</div> <div><br /></div> <div>But visors are what VGR has asked Chalmers to address urgently at the moment, and that is what is being delivered.</div> <div><br /></div> <div>“The last few days have been devoted to making contact with and coordinating across producers. We’re currently working with the majority of manufacturers in Västra Götaland and there are around 250 different producers involved, 50 of which are companies.
