Its aim is that Sweden will regain an internationally leading position in the area. New mathematics is necessary for increasing areas of use in both research and industry. The funding does not target a particular area of mathematics, but will support basic research. </p> <p><a href="http://kaw.wallenberg.org/en/press/investing-millions-mathematics">Press release from the Knut and Alice Wallenberg Foundation &gt;&gt;</a></p> <p><a href="/en/Staff/Pages/wittnyst.aspx"><img width="250" height="300" class="chalmersPosition-FloatRight" alt="David Witt Nyström" src="/SiteCollectionImages/Institutioner/MV/Nyheter/DWN250x300.jpg" style="margin:5px" />David Witt Nyström</a> will receive funding to recruit an international researcher for a postdoctoral position at the Department of Mathematics, Chalmers University of Technology and the University of Gothenburg, Sweden. The proposed researcher Ya Dang will defend his doctoral thesis in May and is a Ph.D. student to Professor Jean-Pierre Demailly, Institute Fourier in Grenoble, who is a world leading researcher in Kähler geometry and who has had collaborations with the Complex Analysis group of the department earlier.</p> <p>Algebraic geometry, which has its roots in classical antiquity, is one of the oldest and most extensive branches of mathematics. New theories within its domain continue to arise, creating new methods for solving as yet unproven problems. Due to the wealth of new ideas, existing fields of mathematical research have been divided into smaller branches, such as complex geometry, which is at the heart of the current project. Algebraic geometry studies sets consisting of solutions to polynomial equations. Such solution sets can take the form of circles, ellipses, spheres, and other geometric objects. For example, two points can be associated with a one-dimensional family of circles crossing both points. This is an example of a linear series, which is an important field of study in algebraic geometry.</p> <p>In the beginning of the 1990s, a Russian-American mathematician, Andrei Okounkov, introduced a way of associating each linear series with a convex body, called an Okounkov body. In 2006 he received the most prestigious award in mathematics, the Field’s medal, which is awarded to eminent mathematicians under forty years old. These convex Okounkov bodies have been successfully used to explain the properties of linear systems. The theory of linear systems is also connected to Kähler geometry, which is a meeting place for complex geometry, differential geometry, and symplectic geometry. It is assumed that the well-known and fundamental results regarding linear series can be generalized to a broader Kähler setting. Such generalizations would have significant consequences for Kähler geometry. Even though it remains to be seen which generalizations are possible, interesting open problems abound. </p> <p><strong><img class="chalmersPosition-FloatRight" alt="Dmitrii Zhelezov" src="/SiteCollectionImages/Institutioner/MV/Nyheter/DZ250x300.jpg" style="margin:5px" />Dmitrii Zhelezov</strong> will receive funding for a postdoctoral position at a foreign university and funding for two years after returning to Sweden. He will hold a postdoctoral position with Professor Endre Szemerédi at Alfréd Rényi Institute of Mathematics in Budapest, Hungary. Dmitrii Zhelezov received his Ph.D. in Mathematics from Chalmers University of Technology in 2016 with the thesis ”<a href="/en/departments/math/news/Pages/Addition-versus-multiplication.aspx">Additively and multiplicatively structured sets</a>” and was employed at the Department of Mathematical Sciences until August 2016.</p> <p>The aim of the project is to study arithmetic combinatorics, a branch of number theory. In contrast to other branches of mathematics, combinatorics focuses on specific problems, which are easy to formulate but notoriously difficult to solve, even when sometimes no mathematical apparatus beyond high school level is necessary for the solution. One of the most famous problems in number theory is the Goldbach conjecture, which states that every even integer greater than two can be expressed as a sum of two prime numbers. In 1742, German mathematician Christian Goldbach formulated the conjecture in a letter to a Swiss mathematician, Leonard Euler, by then already recognized as a genius. Euler’s response confirmed that he thought it was true but he couldn’t prove it. Nor has anyone else been able to do so, in the almost 300 years since. The difficulty in proving the conjecture stems from the fact that it refers to addition, whereas prime numbers are defined through multiplication – an integer is prime if it can be divided only by 1 and by itself. However, not much is known about how prime numbers should be linked to addition. </p> <p>A set of sums consists of the sums of all pairs of elements in a given set. The Goldbach conjecture asks whether the set of sums of prime numbers contains all even numbers greater than two. Initially, easy to handle questions about sets of sums can be studied. Subsequently, more advanced new tools and sophisticated methods, which had been developed for other problems, can be applied. Sets of sums have many other applications as well. The methods and concepts of abstract number theory have been successfully applied to modern cryptography. They are used to process our credit card payments as well as when we surf the internet.<br /><br /><strong>Text</strong>: from the press release of KWA<br /><strong>Photos</strong>: Setta Aspström</p>Fri, 24 Mar 2017 10:00:00 +0100http://www.chalmers.se/en/departments/chem/news/Pages/Polymer-technologist-at-ERC-jubilee.aspxhttp://www.chalmers.se/en/departments/chem/news/Pages/Polymer-technologist-at-ERC-jubilee.aspxChalmers polymer technologist gets to present his work at the ERC jubilee<p><b></b></p><p><a href="/en/Staff/Pages/Christian-Müller.aspx">​Christian Müller, </a>Associate Professor at Chemsitry and Chemical Engieering, is one of three very successful researchers who had the opportunity to present their research under the headline “Beyond expectations” when the European Research Council, ERC, celebrated their 10 year anniversary in Brussels March 21. </p> <blockquote dir="ltr" style="margin-right:0px"><p style="font-size:14px"><span style="font-size:14px">- </span><i style="background-color:initial">The 10th ERC birthday celebration was a remarkable event, with many inspiring presentations.

IEA Bioenergy does not mince words in its critique of UK think-tank Chatham House’s report on the impact of bioenergy on global climate. According to IEA the report &quot;adds to the increasing number of misleading statements in the context of EU discussions about its energy future&quot;, and is backed up by 125 academic signatories worldwide, including Göran Berndes, Chalmers University of Technology.</b></p><div><span style="background-color:initial">With upcoming EU-level discussions on the future of European energy, publications analyzing the contribution of bioenergy have proliferated, including the recent Chatham house report “Woody Biomass for Power and Heat: Impacts on the Global Climate”. </span></div> <div><span style="background-color:initial">IEA Bioenergy (</span><span style="background-color:initial">the International Energy Agency Bioenergy Technology Collaboration Programme) </span><span style="background-color:initial">points out that this report does not present an objective overview of the current state of scientific understanding with respect to the climate effects of bioenergy. The report was analysed by members of the IEA Bioenergy Technology Collaboration Programme with globally recognised expertise in biomass production, carbon accounting and sustainability of biomass.

The report gives an inaccurate interpretation of the impact of harvesting on forest carbon stock, proposes a misguided focus on short-term carbon balances and overstates the climate change mitigation value of unharvested forests. It also assumes that forests would remain unharvested and continue to grow if no biomass was used for bioenergy, which is unrealistic.  <br /></li> <li>Bioenergy and forest products markets and systems. The report considers roundwood to be the main woody bioener<span style="background-color:initial">gy feedstock, but the on-ground reality is that in the EU, by-products and residues from silviculture are the most common type of feedstock. Furthermore, bioenergy can prompt forest owners to plant more trees and invest in sustainable forest management practices. The report largely overlooks the role bioenergy can play in supporting the urgently needed energy system transition.</span><br /></li> <li>Sustainability criteria. The report fails to acknowledge that forest bioenergy is not a single entity but an integral par<span style="background-color:initial">t of the forest management, forestry and energy-industry system that also produces material products. It is therefore unreasonable to expect that the maintenance of the carbon stock in forests would be guaranteed by sustainability criteria applied to the bioenergy category only. </span><br /></li></ol></div> <div> </div> <div>In the report’s general conclusion, it is proposed that &quot;Sustainability criteria should be used to restrict support to mill residues that are produced from legal and sustainable sources”. IEA Bioenergy, together with 125 scientists, strongly disagree with this recommendation, and urge Chatham House to reconsider their recommendations. “We invite Chatham House to engage in a more thoughtful and substantive discussion with technical experts like IEA Bioenergy and review the recommendations.

For the first time, this makes it possible to compare the environmental effects of completely different types of textiles. The results will be used to create a practical tool for clothing manufacturers that want to lighten their environmental load.</b></p><div><span style="background-color:initial"><img src="/SiteCollectionImages/20170101-20170630/Sandra_Roos_Highrez-web.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Every year, 100 million tonnes of new textiles come onto the market and the textile industry has one of the highest turnovers in the world. It has long been understood that textile production has major environmental impact. But it has been difficult for textile companies to determine what choices they can make to reduce the environmental load, due to the wide variation in production processes.</span><br /></div> <div><span style="background-color:initial"><br /></span></div> <div>Now the industry is being given entirely new opportunities. Researcher Sandra Roos has taken an overall approach to the clothing life cycle with her doctoral thesis at Chalmers University of Technology and the research institute Swerea, within the research programme Mistra Future Fashion. Over the course of her five-year project, she studied 30 different sub-processes in textile production. </div> <div><br /></div> <div>‘I have also assessed the toxicity of the chemicals used in the processes,’ says Roos. ‘This is an area where, until now, there were huge knowledge gaps. The sub-processes I studied extend from techniques as different as entirely synthetic textile fibres made of plastic, to cotton production – where farmers cultivate the soil, plant and harvest the cotton, before ginning and preparing it.’ </div> <div><br /></div> <div>The life cycle perspective she used involves an overall assessment, from production to the user phase and product waste management. The effect of background processes such as electricity consumption and mining are also included. The results make it possible to compare textile products that are extremely different to each other, which was not possible before.</div> <div><br /></div> <div>Mistra Future Fashion is a collaborative project between the fashion industry and researchers in Sweden. Their next step will be to transform the results of the thesis to a practical tool that clothing manufacturers can use to improve the environmental performance of their processes and products. The tool is expected to be ready sometime in 2017. This is an important step, since the majority of the environmental load in the clothing life cycle is created in the production phase.</div> <div><br /></div> <div>Unsurprisingly, Sandra Roos’s research shows that conventional cotton growing, where large quantities of insecticides are spread directly on land, stands out as a particularly heavy burden on the environment. Another of her conclusions was more unexpected. </div> <div><br /></div> <div>‘At present, most environmental indices are based on the type of textile fibre used: wool, nylon, polyester or cotton. But that is not where the major environmental impact is found, which is actually in the post-fibre processing stages: spinning, weaving, knitting and, above all, in the dyeing – the wet processing. All the chemicals used in these processes actually make it as hazardous as cotton growing.’</div> <div><br /></div> <h5 class="chalmersElement-H5">Shopping trips cause one of the biggest climate effects of clothing</h5> <div>Roos’s research has also yielded conclusions about which consumer actions are most effective in reducing the environmental load of clothing.</div> <div>‘If you want to be as eco-friendly as possible, there is only one thing you need to remember: use your clothes until they are worn out. That is more important than all other aspects, such as how and where the clothes were manufactured and the materials they are made of.<span style="background-color:initial">‘</span><span style="background-color:initial"> </span></div> <span></span><div></div> <div><br /></div> <div>But in industrialized countries, only a tiny percentage of garments are worn 100 to 200 times, which is usually the potential lifetime. In Sweden, for example, consumers buy an average of 50 new garments per person and year. Similar figures apply to the rest of Europe and the United States.</div> <div><br /></div> <div>Such high consumption makes how the clothing is produced more important. But it is difficult for consumers to get information about the most important aspects – those related to processing of the textile materials. Instead, Sandra Roos has another recommendation to the average consumer who wants to live greener: </div> <div><br /></div> <div>‘Think about how you travel to the clothes shop. When it comes to impact on the climate, this is the factor that is the easiest to influence, other than buying fewer garments, and one that has substantial effect. Since many shopping trips are taken by car, consumer travel accounts for a large share of the climate load during the clothing life cycle. In Sweden, that share is a full 22 percent.’<br /><br /><strong>Text:</strong> Johanna Wilde and Christian Löwhagen<br /><strong>Photo:</strong> Sandra Roos <span>and Christian Löwhagen<span style="display:inline-block"></span></span><br /></div> <div><br /><a href="http://www.mynewsdesk.com/uk/chalmers/pressreleases/the-fashion-industry-gains-new-tool-to-reduce-its-environmental-load-1853732">Read the full press release &quot;The fashion industry gains new tools to reduce its environmental load&quot;</a>.<br /></div> <div><h5 class="chalmersElement-H5">Facts: Climate impact from the various phases of our clothing’s life cycle</h5> <div><img src="/SiteCollectionImages/Institutioner/EoM/Nyheter/Diagram-textiles_400.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />The chart shows climate impact generated by Swedes during the various phases of the clothing life cycle.  A similar pattern applies to the rest of Europe and the United States.</div> <div>Production accounts for 70 percent. Distribution of the clothes until they reach consumers accounts for only 4 percent – even though the clothes are mainly made in countries far away from Sweden.  Consumer shopping trips account for a full 22 percent.

A recently published scientific paper shows that health care professionals get vital information and can quickly decide on appropriate treatment if patients are examined using a microwave helmet.</b></p>​The study demonstrates a new health care application for microwave measurements. Previously, microwave measurements have been used to distinguish stroke caused by bleeding in the brain from stroke caused by cloth.<br /><br />The new study shows that the technology also applies to patients affected by traumatic brain injury, which is the most common cause of death and disability among young people. This type of injuries are often caused by traffic accidents, assaults or falls. An estimated 10 million people are affected annually by traumatic brain injuries.<br /><br />The study compared 20 patients hospitalized for surgery of chronic subdural hematoma – a serious form of intracranial bleeding – with 20 healthy volunteers. The patients were examined with microwave measurements which were compared to traditional CT scans. The results show that microwave measurements have great potential to detect intracranial bleeding in this group of patients.<br /><br />“The result is very promising even though the study is small and only focused on one type of head injury. The microwave helmet could improve the medical assessment of traumatic head injuries even before the patient arrives at the hospital”, says Johan Ljungqvist specialist in neurosurgery at the Sahlgrenska University Hospital. “The result indicates that the microwave measurements can be useful in ambulances and in other care settings.”<br /><span><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Strokefinder/MikaelPersson_200px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></span><br />Further studies of acute head injury patients are ongoing and planned in Sweden and abroad.<br /><br />“Microwave technology has the potential to revolutionize medical diagnostics by enabling faster, more flexible and more cost-effective care”, says Mikael Persson, professor of biomedical engineering at Chalmers University of Technology. “In many parts of the world microwave measurements systems can become a complement to CT scans and other imaging systems, which are often missing or have long waiting lists.”<br /><img src="/SiteCollectionImages/Institutioner/s2/Nyheter%20och%20kalendarium/Strokefinder/Mikael_Elam_200px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br />“It is challenging to develop a new clinical methodology, from early tests to a device for clinical use in a hyperacute clinical environment where routine care of patients cannot be delayed.

The purpose is to develop techniques that make it possible to identify disturbances in operating nuclear reactors at an early stage. During four years, the European Commission will invest 5,1 million euros in the project Cortex, managed by Christophe Demazière and Paolo Vinai, Professors at the Department of Physics.</b></p>​“We believe that these techniques can be applied to both the existing fleet of operating nuclear reactors and the ones that will be built in the future. This will contribute to a lowering of the CO2 footprint on the environment, and to a more reliable production of cheap base-load electricity for the consumers. An additional aspect is the ageing fleet of reactors in Europe: operational problems are expected to be more frequent in these plants and we need to detect such problems at an early stage”, says Christophe Demazière. <br /><p></p> <p>The project is funded within the EU program Horizon2020 and is a large international collaboration involving 17 European partners, two partners from Japan, and one partner from USA. The consortium consists of several research groups from academia, research institutes, safety and technical organizations, and private companies servicing the nuclear industry. In addition, this project is in line with the expertise and competence developed at Chalmers by Professor Imre Pázsit, who is also involved in the project. </p> “The scope of the research is very interdisciplinary. The project will combine the work of experts in different fields spanning from nuclear reactor physics to artificial intelligence and from computational to experimental physics. An advisory end-user group will help keep the research aligned with the needs of the nuclear industry and to maximize the impact in terms of industrial innovation”, says Paolo Vinai. <p>The Swedish nuclear power plant Ringhals takes part in the advisory group.<br /><br />Text: Mia Halleröd Palmgren<br /><a href="mailto:mia.hallerodpalmgren@chalmers.se">mia.hallerodpalmgren@chalmers.se</a><br /><br /><strong>More information:</strong><br /><a href="/en/Staff/Pages/Christophe-Demazière.aspx">Christophe Demazière</a>, Professor, Division of Subatomic and Plasma Physics, Department of Physics, Chalmers, +46 31 772 30 82, <a href="mailto:demaz@chalmers.se">demaz@chalmers.se</a></p> <p></p> <p><a href="/en/Staff/Pages/Paolo-Vinai.aspx">Paolo Vinai</a>, Associate Professor, Division of Subatomic and Plasma Physics, Department of Physics, Chalmers, +46 31 772 30 80, <a href="mailto:vinai@chalmers.se">vinai@chalmers.se<br /></a></p> <p><br /><a href="mailto:vinai@chalmers.se"></a> </p> <p></p> <p><strong>More about Cortex: </strong><br />Cortex (CORTEX) stands for core monitoring techniques and experimental validation and demonstration.

Such techniques are based on the monitoring of stationary fluctuations in the neutron flux in reactors. A tool that was earlier developed at Chalmers to calculate the effect of known perturbations will be used in the project.

But none have succeeded, until now. With new findings from Chalmers the enzyme FAS has started to produce sustainable chemicals for biofuels.</b></p>​We are in great need of sustainable and clean alternatives to oil-derived products. One of the choices at hand is to produce chemicals and biofuels from sustainable biomass.<br /><br />To do this, researchers in the group of Professor Jens Nielsen at the Department of Biology and Biological Engineering is hard at work trying to design yeast cell factories that can actually produce the chemicals we need in a sustainable way. The group now had a major break-through, as they developed a novel method of changing the enzyme FAS, fatty acid synthase, into producing new products.<br />– This enzyme normally synthesizes long chain fatty acids, but we have now modified it into synthesizing medium chain fatty acids and methyl ketones – chemicals that are components in currently used transportation fuels, Post-doc Zhiwei Zhu explains.<br />– In other words: We are able to produce gasoline and jet fuel alternatives by yeast cell factories, and this has never been done before.<br /><br />The important enzyme was first elucidated by Nobel Prize winner Feodor Lynen, and many researchers have in recent years tried to modify it. But it seemed very hard, or close to impossible – until now.<br />– We did not expect this. Actually, it was thought by the scientific community that this rigid enzyme was not readily amenable to manipulation, says Zhiwei Zhu.<br /><br />The findings are in fact a result of a lucky break. A few years ago, the researchers occasionally found a FAS which had two acyl carrier protein domains.<br />– We first tried to change this FAS by replacing one of its acyl carrier protein domains with a foreign enzyme to render it new activities, and surprisingly it worked. Then we implemented such modification in other fungal FASs and found this approach versatile.<br /><br />The researchers are now focusing on using the modified enzyme to build yeast cell factories for production of chemicals and fuels. An invention patent has been filed, and the company Biopetrolia – a spin-off company to the Chalmers department – are closely involved, trying to further develop the technique to make it economically viable.<br /><br />But as a researcher, Zhiwei Zhu also has a long-term goal of his own:<br />– I am also interested in deeply revealing the biochemical and structural basis of this novel modification in fungal FAS.<br /><br /><br />Link to the scientific article: <a href="http://www.nature.com/nchembio/journal/vaop/ncurrent/full/nchembio.2301.html">Expanding the product portfolio of fungal type I fatty acid synthases</a> <br /><br />Text: Mia Malmstedt<br />In the photo: Zhiwei Zhu, Jens Nielsen and Biopetrolia CEO Anastasia Krivoruchko.
