News: KoM related to Chalmers University of TechnologyWed, 17 Apr 2019 11:02:15 +0200 materials with ultrafast connections<p><b>Through magic twist angles and unique energy states, it is possible to design tailor-made, atomically thin materials that could be invaluable for future electronics. Now, researchers at Chalmers University of Technology, Sweden, and Regensburg University in Germany have shed light on the ultrafast dynamics in these novel materials. The results were recently published in the prestigious journal Nature Materials.​​​</b></p><div><div>Imagine you are building an energy-efficient and super-thin solar cell. You have one material that conducts current and another that absorbs light. You must therefore use both materials to achieve the desired properties, and the result may not be as thin as you hoped.</div> <div><br /></div> <div>Now imagine instead that you have atomically thin layers of each material, that you place on top of each other. You twist one layer towards the other a certain amount, and suddenly a new connection is formed, with special energy states – known as interlayer excitons – that exist in both layers. You now have your desired material at an atomically thin level.</div> <div><br /></div> <div>Ermin Malic, researcher at Chalmers University of Technology, in collaboration with German research colleagues around Rupert Huber at Regensburg University, has now succeeded in showing how fast these states are formed and how they can be tuned through twisting angles. Stacking and twisting atomically thin materials like Lego bricks, into new materials known as ‘heterostructures’, is an area of research that is still at its beginning.</div></div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/ErminMalic_190415_05_350xwebb.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><div>“These heterostructures have tremendous potential, as we can design tailor-made materials. The technology could be used in solar cells, flexible electronics, and even possibly in quantum computers in the future,” says Ermin Malic, Professor at the Department of Physics at Chalmers.</div> <div><br /></div> <div>Ermin Malic and his doctoral students Simon Ovesen and Samuel Brem recently collaborated with researchers at Regensburg University. The Swedish group has been responsible for the theoretical part of the project, while the German researchers conducted the experiments. For the first time, with the help of unique methods, they succeeded in revealing the secrets behind the ultrafast formation and dynamics of interlayer excitons in heterostructure materials. They used two different lasers to follow the sequence of events. By twisting atomically thin materials towards each other, they have demonstrated that it is possible to control how quickly the exciton dynamics occurs.</div> <div><br /></div> <div>“This emerging field of research is equally fascinating and interesting for academia as it is for industry,” says Ermin Malic. He leads the Chalmers Graphene Centre, which gathers research, education and innovation around graphene, other atomically thin materials and heterostructures under one common umbrella.</div> <div><br /></div> <div>These kinds of promising materials are known as two-dimensional (2D) materials, as they only consist of an atomically thin layer. Due to their remarkable properties, they are considered to have great potential in various fields of technology. Graphene, consisting of a single layer of carbon atoms, is the best-known example. It is starting to be applied in industry, for example in super-fast and highly sensitive detectors, flexible electronic devices and multifunctional materials in  automotive, aerospace and packaging industries.</div> <div><br /></div> <div>But graphene is just one of many 2D materials that could be of great benefit to our society. There is currently a lot of discussion about heterostructures consisting of graphene combined with other 2D materials. In just a short time, research on heterostructures has made great advances, and the journal Nature has recently published several breakthrough articles in this field of research. </div> <div><br /></div> <div>At Chalmers, several research groups are working at the forefront of graphene. The Graphene Centre is now investing in new infrastructure in order to be able to broaden the research area to include other 2D materials and heterostructures as well.</div> <div><br /></div> <div>“We want to establish a strong and dynamic hub for 2D materials here at Chalmers, so that we can build bridges to industry and ensure that our knowledge will benefit society,” says Ermin Malic.</div></div> <div>​<br /></div> <div></div> <div><span style="background-color:initial">Text and image: Mia Halleröd Palmgren, </span><a href=""></a><br /></div> <div>Translation to English: Joshua Worth,<a href=""></a></div> <div><br /></div> <div>Read the scientific paper <span style="background-color:initial"><a href="">Ultrafast transition between exciton phases in van der Waals heterostructures</a> </span><span style="background-color:initial">in Nature Materials.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release from Regensburg University, Germany. </a></div> <div><br /></div> <div><a href="/sv/centrum/graphene/Sidor/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about the Graphene Centre at Chalmers (GCC)</a></div> <span style="background-color:initial"></span></div> <div><br /></div> <h3 class="chalmersElement-H3">For more information: </h3> <div><a href="/sv/personal/Sidor/ermin-malic.aspx">Ermin Malic,​</a> Professor, Department of Physics and Director of the Graphene Centre, Chalmers University of Technology, Sweden, +46 31 772 32 63, +46 70 840 49 53, <a href="">​</a></div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/750x340/SamuelBremErminMalic_20190415_bannerwebb.jpg" alt="" style="margin:5px" /><br />Professor Ermin Malic (to the right) and his doctoral students Samuel Brem (left) and <span style="background-color:initial">Simon Ovesen (not pictured) r</span><span style="background-color:initial">ecently collaborated with researchers at Regensburg University.

Currently, development of digital systems is under way that in real time will control and distribute the available power, depending on such factors as how much each driver is prepared to pay, and how fast the vehicle must be fully charged for the next trip.</b></p>​<img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smartare%20laddning%20nyckeln%20till%20elektromobilitet/Lang_Tong2_300px.jpg" class="chalmersPosition-FloatLeft" alt="Lang Tong" style="margin:5px" /><span style="background-color:initial">During nine months, Chalmers University of Technology is reinforced by Professor Lang Tong from Cornell University, USA. As a guest professor, one of his tasks will be to contribute to Chalmers' research in the field of electric power engineering, primarily focusing on digitalization in large-scale infrastructure for the charging of electric vehicles.</span><div><br /></div> <div>“Being a researcher interested in electromobility, Chalmers is an attractive place to visit”, says Lang Tong. “The close relation to industry as well as Chalmers' often application-driven research on electrified vehicles are interesting to me. In return, I hope to be able to contribute with my knowledge of applying ideas from artificial intelligence and data science in power and energy systems.”</div> <div><br /></div> <div>Lang Tong was in 2018 awarded the prestigious Fulbright Distinguished Chair in Alternative Energy Technology. His visit to Chalmers is funded by the Fulbright Scholar Program, a bi-national organization promoting exchange between Sweden and the US with government funding from both nations.</div> <div><br /></div> <h5 class="chalmersElement-H5">Developing smart charging of electrified vehicles</h5> <div>He is currently engaged in a collaborative research project at the department of Electrical Engineering aiming at developing technology and software systems for smart charging of electrified vehicles.</div> <div><br /></div> <div>“In 12-14 years, the proportion of electric cars is forecasted to increase to about 10 percent of the vehicle fleet”, Lang Tong says. “The infrastructure for charging the vehicles must, by then, be upgraded to become sufficient and robust enough to handle the increasing demand. Otherwise the lack of infrastructure risks hampering the development.”</div> <div><br /></div> <div>What will happen if thousands of drivers in Gothenburg, when they get home from work in the evening, plug in their electric cars for charging at the same time?</div> <div><br /></div> <div>“Well, it won´t be possible to charge all those vehicles at the same time”, Lang Tong notes. “The local distribution network will get overloaded; the power demand will be too heavy.”</div> <div><br /></div> <div>Instead, the solution lies in applying digital systems that in real time control and distribute the available power depending on the demand. </div> <div><br /></div> <div>“To match supply and demand of energy the development of smart systems is required. The systems need to be so smart that they also can take into account such factors as how much each driver is prepared to pay, and how fast the vehicles must be fully charged for the next trip.”</div> <div><br /></div> <div>At times, when there is a high strain on the grid from prioritized electrical equipment, the charging of some vehicles could be planned to be conducted later. Or the stored energy in the batteries of the car could even be used as a reinforcement or backup to the grid.</div> <div><br /></div> <h5 class="chalmersElement-H5">The potential of digitalization</h5> <div>“I am very pleased with the help Lang Tong gives us to grasp the new possibilities and to develop the use of data science and artificial intelligence in our research and in our education of power engineers for the future,” says Jörgen Blennow, Head of division Electric Power Engineering. “Digitalization will emerge in more and more areas, and it is important for us to fully understand what that means in terms of reliability, controllability and optimization of power systems.”</div> <div><br /></div> <div>During his stay at Chalmers, Professor Lang Tong also will be giving courses on machine learning and artificial intelligence in power systems to doctoral students.</div> <div><br /></div> <h5 class="chalmersElement-H5">A sustainable approach to future power systems</h5> <div>“In Scandinavia, I experience that there are strong environmental concerns against the use of fossil fuels, which in turn support the development of more sustainable solutions for transportation, generation of electricity and heating”, Lang Tong says. “However, for the electrified transportation system to be expanded on a large scale, there is also a need for political long-term policies and incentives supporting electrification, along with the expansion of infrastructure for charging the vehicles.”</div> <div><br /></div> <div>“The current power system is going through a transformation”, he continues. “In my opinion, this development is driven by two technological areas that require the attention of the researchers of today. On one hand, there is the development of electromobility. On the other hand, there is the need of an expanded system for solar energy combined with batteries to store the energy. A new power system design will make it possible for people to produce their own energy, in a small scale at home, and to save surplus electricity for later.” </div> <div><br /></div> <div>If electricity does not necessarily need to be produced at the same time as it is consumed, to maintain the balance in the electrical grid, conditions are created for more producers to enter the system, while a higher share of renewable energy sources also can be introduced.</div> <div><br /></div> <h5 class="chalmersElement-H5">Visiting together</h5> <div>Professor Lang Tong and his wife, Professor Qing Zhao also from Cornell University, have accompanied each other to Sweden and Chalmers.

Unfortunately, hydrogen gas is highly flammable when mixed with air, so very efficient and effective sensors are needed. Now, researchers from Chalmers University of Technology, Sweden, present the first hydrogen sensors ever to meet the future performance targets for use in hydrogen powered vehicles.</b></p><div><p class="chalmersElement-P">​<span style="background-color:initial">The researchers’ ground-breaking results were recently <a href="">published in the prestigious scientific journal Nature Materials.​</a> The discovery is an optical nanosensor encapsulated in a plastic material. The sensor works based on an optical phenomenon – a plasmon – which occurs when metal nanoparticles are illuminated and capture visible light. The sensor simply changes colour when the amount of hydrogen in the environment changes.</span></p> <p class="chalmersElement-P">The plastic around the tiny sensor is not just for protection, but functions as a key component. It increases the sensor’s response time by accelerating the uptake of the hydrogen gas molecules into the metal particles where they can be detected. At the same time, the plastic acts as an effective barrier to the environment, preventing any other molecules from entering and deactivating the sensor. The sensor can therefore work both highly efficiently and undisturbed, enabling it to meet the rigorous demands of the automotive industry – to be capable of detecting 0.1 percent hydrogen in the air in less than a second.</p> <img src="/SiteCollectionImages/Institutioner/F/350x305/Ferry_portratt_350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;height:216px;width:250px" /><p class="chalmersElement-P">“We have not only developed the world's fastest hydrogen sensor, but also a sensor that is stable over time and does not deactivate. Unlike today's hydrogen sensors, our solution does not need to be recalibrated as often, as it is protected by the plastic,” says Ferry Nugroho, a researcher at the Department of Physics at Chalmers.</p> <p class="chalmersElement-P">It was during his time as a PhD student that Ferry Nugroho and his supervisor Christoph Langhammer realised that they were on to something big. After reading a scientific article stating that no one had yet succeeded in achieving the strict response time requirements imposed on hydrogen sensors for future hydrogen cars, they tested their own sensor. They realised that they were only one second from the target – without even trying to optimise it. The plastic, originally intended primarily as a barrier, did the job better than they could have imagined, by also making the sensor faster. The discovery led to an intense period of experimental and theoretical work.</p> <p class="chalmersElement-P">“In that situation, there was no stopping us. We wanted to find the ultimate combination of nanoparticles and plastic, understand how they worked together and what made it so fast. Our hard work yielded results. Within just a few months, we achieved the required response time as well as the basic theoretical understanding of what facilitates it,” says Ferry Nugroho.</p> <p class="chalmersElement-P">Detecting hydrogen is challenging in many ways. The gas is invisible and odourless, but volatile and extremely flammable. It requires only four percent hydrogen in the air to produce oxyhydrogen gas, sometimes known as knallgas, which ignites at the smallest spark. In order for hydrogen cars and the associated infrastructure of the future to be sufficiently safe, it must therefore be possible to detect extremely small amounts of hydrogen in the air. The sensors need to be quick enough that leaks can be rapidly detected before a fire occurs.</p> <img src="/SiteCollectionImages/Institutioner/F/350x305/ChristophLanghammerfarg350x305.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;height:216px;width:250px" /><p class="chalmersElement-P">​“It feels great to be presenting a sensor that can hopefully be a part of a major breakthrough for hydrogen-powered vehicles. The interest we see in the fuel cell industry is inspiring,” says Christoph Langhammer, Professor at Chalmers Department of Physics.</p> <p class="chalmersElement-P">Although the aim is primarily to use hydrogen as an energy carrier, the sensor also presents other possibilities. Highly efficient hydrogen sensors are needed in the electricity network industry, the chemical and nuclear power industry, and can also help improve medical diagnostics.</p> <p class="chalmersElement-P">“The amount of hydrogen gas in our breath can provide answers to, for example, inflammations and food intolerances. We hope that our results can be used on a broad front. This is so much more than a scientific publication,” says Christoph Langhammer.</p> <p class="chalmersElement-P">In the long run, the hope is that the sensor can be manufactured in series in an efficient manner, for example using 3D printer technology.<br /><br /></p> <div><strong>Text: </strong><span style="background-color:initial">Mia Halleröd Palmgren,</span><span style="background-color:initial"> </span><a href=""></a> and <span style="background-color:initial">Joshua Worth,</span><a href=""></a><span style="background-color:initial">​ </span></div> <div><strong>Image</strong> of C<span style="background-color:initial">hristoph</span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"></span><span style="background-color:initial"> Langhammer: Henrik Sandsjö</span><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><strong>Illustration</strong> of the sensor technique: </span><span style="background-color:initial">Ella Marushchenko<br /></span><span style="background-color:initial">Images of Ferry Nugroho, the sensor and the group picture: Mia Halleröd Palmgren​</span></div></div> <div><img src="/SiteCollectionImages/Institutioner/F/750x340/Vatgassensor_750x340.jpg" alt="" style="color:rgb(33, 33, 33);font-family:&quot;open sans&quot;, sans-serif;font-size:24px;background-color:initial;margin:5px" /> ​</div> <h4 class="chalmersElement-H4"><span>Facts: The world's fastest hydrogen sensor​</span><span>​</span></h4> <div><span style="color:rgb(33, 33, 33);font-family:&quot;open sans&quot;, sans-serif;background-color:initial"><br /></span></div> <div><ul><li><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/vätgassensor_amerikansk_illu350x460.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:250px;height:324px" /><span style="background-color:initial">The Chalmers-developed sensor is based on an optical phenomenon – a plasmon – which occurs when metal nanoparticles are illuminated and capture light of a certain wavelength.</span></li> <li><span style="background-color:initial"></span>The optical nanosensor contains millions of metal nanoparticles of a palladium-gold alloy, a material which is known for its sponge-like ability to absorb large amounts of hydrogen.

The aim is for Sweden to recover its position at the international cutting edge by giving the best young researchers international experience and by recruiting young as well as more experienced mathematicians to Sweden.</p> <p><a href="">Press release from the Knut and Alice Wallenberg Foundation &gt;&gt;</a></p> <h4><a href="">New solutions to ancient problems </a></h4> <p><img class="chalmersPosition-FloatRight" alt="Photo Julia Brandes" src="/SiteCollectionImages/Institutioner/MV/Nyheter/JuliaBrandes200x250.jpg" style="margin:5px" />Julia Brandes plans in her project to make use of the improved precision of the circle method to study the number of integer solutions to certain equation systems under certain extra conditions. Two cases are particularly interesting. On the one hand, she studies such equation systems where the variables lie in widely differing ranges – some variables are large while others are small. The other part of the project is about solutions which, if they are written in a number system with a certain prime base p, avoid certain digits. Such numbers are of interest because they have a strange but regular fractal structure. By making use of this special structure it is expected that it will be possible to predict how many such solutions there are.</p> <p>– I think that research in mathematics should be supported for two reasons. On the one hand, there is a certain romance in fundamental mathematical research, as in fundamental research in terms of space travel or particle accelerators. That romance is not to be underestimated as the source of inspiration for future researchers. How many young people interested in mathematics do not read popular science books on, for example, Ramanujan or Fermat’s last theorem? The second reason is less romantic: A large part of the science and engineering research had not been imagined without mathematics.</p> <p><a href="">The whole interview with Julia Brandes at the Faculty of Science web site, in Swedish &gt;&gt;</a></p> <h4><a href="">Cosmic plasma in a mathematical suit </a></h4> <p><img class="chalmersPosition-FloatRight" alt="Photo Stephen Pankavich" src="/SiteCollectionImages/Institutioner/MV/Nyheter/StephanPankavich200x250.jpg" style="margin:5px" />Stephen Pankavich is an associate professor at the Colorado School of Mines, Golden, USA. He will be a visiting professor at the Department of Mathematical Sciences and together with researchers here develop new methods for solving different mathematical problems in the kinetic theory of plasma dynamics. Plasma is a special kind of gas in which electrons are stripped from the atoms, making the gas electrically charged. Plasma is therefore of practical interest; for example, plasma engines have been developed to drive probes that are sent far out in space. Plasma is regarded as the fourth form of matter, after gases, liquids and solids, and is the most common state of matter in the universe. Galactic clouds, tails of comets and the solar wind, among many other things, consist of plasma’s electrically charged particles.</p> <p>The motions of plasma are described by a number of complicated partial differential equations. The purpose of this project is to show that the equations have realistic solutions, and to determine the properties of these solutions, such as development over time, and calculate their sensitivity with respect to the plasma’s state, such as its mass, charge, or temperature. Since the mathematical models always have physical counterparts, the challenge of analyzing a problem mathematically also becomes a challenge in understanding the physical phenomena it describes at a deeper level. Therefore, a discovery of a specific behavior in solutions to partial differential equations can be translated into real knowledge of problems in plasma physics or astrophysics.</p> <h4><a href="">New tools for capturing the unruly </a></h4> <p><img class="chalmersPosition-FloatRight" alt="Photo Jakob Hultgren" src="/SiteCollectionImages/Institutioner/MV/Nyheter/JakobHultqvistKAW200x250.jpg" style="margin:5px" />Jakob Hultgren receives a postdoctoral position at a foreign university and funding for two years after his return to Sweden. The project’s title is “New notions of canonical metrics and stability in complex geometry” and contains two separate parts. The first is based on the new types of canonical metrics and stability conditions that Jakob introduced together with David Witt Nyström when he was a doctoral student (<a href="/sv/institutioner/math/nyheter/Sidor/Pa-jakt-efter-det-unika.aspx">interview before the thesis defence at Chalmers University of Technology last year</a>, in Swedish). There are many different things that needs investigation, but the overall goal is to establish new connections between geometric analysis and other fields such as algebraic geometry and probability theory. The second part of the project is about a question related to mirror symmetry in string theory that was posed in the early 2000s (the Gross-Wilson conjecture). This is a very algebraic problem and the new part of the approach is an analytical tool that Jakob developed together with Magnus Önnheim at Chalmers. </p> <p>– At the University of Maryland, I will mainly work with Yanir Rubinstein. He has made many important contributions to the field but is also very broad and flexible in his interests, so there will probably appear many unexpected and interesting angles during the time of the project. Many of our ideas and tools come from geometric analysis where <a href=";strukt_tid=73996">Karen Uhlenbeck, who received the Abel Prize last week</a>, is active.<br />For example, one of the inspirations for the first part of the project is one of her results: the Donaldon-Uhlenbeck-Yau theorem.<br /><br /><strong>Texts</strong>: Carina Eliasson, Simone Calogero, Jakob Hultgren<br /><strong>Photos</strong>: Johan Bodell (Julia Brandes), private (Stephen Pankavich, Jakob Hultgren)</p>Thu, 28 Mar 2019 03:30:00 +0100 consumption linked to tropical deforestation<p><b>A sixth of all emissions resulting from the typical diet of an EU citizen can be directly linked to deforestation of tropical forests. Two new studies, from Chalmers University of Technology, Sweden, shed new light on this impact, by combining satellite imagery of the rainforest, global land use statistics and data of international trade patterns.  “In effect, you could say that the EU imports large amounts of deforestation every year. If the EU really wants to achieve its climate goals, it must set harder environmental demands on those who export food to the EU,” says Martin Persson from Chalmers, one of the researchers behind the studies.</b></p><div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/Martin-Florence.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />​<span style="background-color:initial">The link between production of certain foods and deforestation has been known before. But what Martin Persson and Chalmers colleague Florence Pendrill have now investigated is the extent to which deforestation in the tropics is linked to food production, and then where those foods are eventually consumed. In the first study (</span><a href="" style="outline:currentcolor none 0px">Deforestation displaced: trade in forest-risk commodities and the prospects for a global forest transition</a>)<span style="background-color:initial">, they focused on how the expansion of cropland, pastures, and forestry plantations has taken place at the expense of the rainforest.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">“We can see that more than half of deforestation is due to production of food and animal feed, such as beef, soy beans and palm oil. There is big variation between different countries and goods, but overall, exports account for about a fourth of that deforestation which is connected to food production. And these figures have also increased during the period we looked at,” says Florence Pendrill.</span></div> <div> </div> <div><br /></div> <div>Using this information, the researchers investigated, in the second study (<span style="background-color:initial">(</span><a href="" style="outline:currentcolor none 0px">Agricultural and forestry trade drives large share of tropical deforestation emissions</a>)<span style="background-color:initial">,</span><span style="background-color:initial"> the amount of carbon dioxide </span><span style="background-color:initial">emissions resulting from this production (see the picture below), and where the produce is then consumed.

Furthermore, the EU shall soon present a plan for how to reduce its contribution to deforestation.</span></div> <span></span><div></div> <div> </div> <div><br /></div> <div>The EU already has strict requirements in place connected to deforestation which producers of timber and wood products must adhere to in order to export their goods to the EU. This demonstrates their ability to influence other countries’ work in protecting the rainforest.</div> <div><br /></div> <div> </div> <div>“Now, as the connection between food production and deforestation is made clearer, we should start to discuss possibilities for the EU to adopt similar regulations for food imports. Quite simply, deforestation should end up costing the producer more. If you give tropical countries support in their work to protect the rainforest, as well as giving farmers alternatives to deforestation to increase production, it can have a big impact,” says Florence Pendrill. </div> <div><br /></div> <div> </div> <div>The current studies were done in collaboration with researchers from the Stockholm Environment Institute in Sweden, Senckenberg Biodiversity and Climate Research Centre in Germany, and NTNU, the Norwegian University of Science and Technology. They are a continuation of research which was done through the Prince project (Policy Relevant Indicators for National Consumption and Environment), where the connections between Swedish consumption and emissions from deforestation were presented in the autumn. </div> <div><br /></div> <div> </div> <div>The studies indicate that, although there is a big variation between different EU countries, on average a sixth of the emissions from a typical EU diet can be directly traced back to deforestation in the tropics. Emissions from imports are also high when compared with domestic agricultural emissions. For several EU countries, import emissions connected to deforestation are equivalent to more than half of the emissions from their own, national agricultural production. </div> <div><br /></div> <div> </div> <div>“If the EU really wants to do something about its impact on the climate, this is an important emissions source. There are big possibilities here to influence production so that it avoids expanding into tropical forests,” says Martin Persson. </div> <div><br /></div> <div> </div> <div>Above all, Martin Persson believes the responsibility for achieving these changes lies with bigger actors, such as countries and large international organisations. But he also sees a role for the consumer to get involved and have an influence.</div> <div><br /></div> <div> </div> <div>“Public opinion is vital for the climate question – not least in influencing politicians, but also commercially. We can see already that several companies have made commitments to protecting tropical forests, through voluntarily pledging to avoid products which are farmed on deforested land. And in large part, that results from the fact that popular opinion is so strong on this issue,” he concludes. </div> <div><br /></div> <div><em>Text: Christian Löwhagen. </em></div> <div><em>Photos: Anna-Lena Lundqvist and Christian Löwhagen.</em></div> <em> </em><div><em> </em></div> <em> </em><div>​<br /></div> <div> </div> <div><h5 class="chalmersElement-H5"><span>More information on: Carbon dioxide emissions due to tropical deforestation</span></h5></div> <h5 class="chalmersElement-H5"> </h5> <div>For the period 2010–2014, the researchers estimate net emissions of 2.6 gigatonnes of carbon dioxide due to deforestation associated to the expansion of croplands, pastures and forestry plantations in the tropics.

These so-called sub-cycle pulses can be used to probe and control matter in unique ways. Conventional methods can only produce sub-cycle pulses of limited field strength: above a certain threshold the amplifying medium would be ionized by the intense fields. The researchers propose to use an electron beam in a plasma, which is not subject to a damage threshold, as an amplifying medium for a seed electromagnetic pulse. To ensure that energy is transferred from the electron beam to the pulse in such a way that a sub-cycle pulse is produced, the beam needs to be introduced at an appropriate phase of the oscillation of the electromagnetic field. This can be achieved by using a mirror to reflect the seed pulse while the electron beam is being injected. This scenario leads to significant amplification of the seed pulse and the formation of an intense, isolated, sub-cycle pulse. Readily available terahertz seed pulses and electron bunches from laser-plasma accelerators could generate mid-infrared sub-cycle pulses with millijoule-level energies, which are highly desirable as probes of matter but not possible to produce with conventional sources.</div> <div><br /> </div> <h4 class="chalmersElement-H4">For more information: </h4> <div><a href="">Illia Thiele</a>, Postdoctoral researcher, Department of Physics, Chalmers University of Technology, +46 76 607 82 79,<a href=""></a><br /></div> <div> </div> <div><span style="background-color:initial"><a href="/en/staff/Pages/Tünde-Fülöp.aspx">Tünde Fülöp,​</a> Professor, Department of Physics, Chalmers University of Technology, +46 72 986 74 40, </span><a href=""></a></div> <div><br /><a href=";disableRedirect=true&amp;returnUrl=;userId=xsimev">Evangelos Siminos</a>, Assistant Professor, Department of Physics, University of Gothenburg</div></span><div><span style="background-color:initial">+46 31 786 9161, <a href=""></a></span></div>Tue, 19 Mar 2019 07:00:00 +0100 giants: Alma witnesses the birth of a massive binary star<p><b>​A team of astronomers, among them Jonathan Tan (Chalmers) have made new observations with Alma of a molecular cloud that is collapsing to form two massive protostars that will eventually become a binary star system.</b></p>​<span style="background-color:initial">While it is known that most massive stars possess orbiting stellar companions it has been unclear how this comes about.

Now, a new ISO standard will help companies valuate and manage the impact of their environmental damage, by providing a clear figure for the cost of their goods and services to the environment.</b></p><p></p> <div>We know what goods and services cost us, but what does the environment pay? For many years now, this question has been the focus of several global companies and researchers at the Swedish Life Cycle Center, a competence centre hosted by Chalmers University of Technology, Sweden. For as long as 30 years, they have been using the so-called <a href="">EPS tool</a> to place a monetary value on environmental damage.</div> <div> </div> <div>Over the past three years, Bengt Steen, Professor Emeritus at Chalmers, has led the development of a new ISO standard for monetary valuation. The work has been in collaboration with AB Volvo, Essity, Nouryon (formerly Akzo Nobel Specialty Chemicals) and the IVL Swedish Environmental Institute. The initiative was taken by Swedish Life Cycle Center.</div> <div> </div> <div>“One reason why sustainable development does not move fast enough is that it is not linked to the economy,” says Bengt Steen. “Experts speak one language, and business leaders another. The negative environmental effects often remain just figures on paper. But by translating environmental issues into a monetary value, it becomes much easier to present the whole picture to an organisation and influence their strategic decisions.”</div> <div> </div> <div>Unlike many other tools, EPS weighs different types of environmental impacts, not just the effect on climate. For example, a given course of action may be beneficial for the climate but damaging for biodiversity or public health. With this approach, an overall picture is reached of what impact a product or service has on the environment, throughout its entire life cycle. A large variety of aspects are covered. Until now, this has been complex work, requiring a lot of manual input and expert knowledge.</div> <div> </div> <div>“With this standard, we can remove several of the obstacles to increased usage of monetary valuation. In a few years, when users can routinely assess the total environmental damage cost for a given investment, supplier, product design and so on, environmental issues can occupy a more central place in the boardroom. Costs to the environment can be presented side by side with profits for the company,” says Bengt Steen.</div> <div> </div> <div>Emma Ringström, Sustainability Manager at Nouryon, says that monetary valuation has given the company much valuable insight.</div> <div> </div> <div>“We have made monetary valuation of a number of our value chains and included the results of this ​​in our annual report. The analyses include financial, social, human and environmental capital, where environmental capital is partly calculated with life cycle assessment and with EPS as a valuation method. The tool has also used to see which activities in the value chain have a large total environmental damage cost compared to profit, and therefore need to be prioritised to become more sustainable.”</div> <div> </div> <div>Although tools such as EPS have existed for 30 years, and many companies like Nouryon use them to calculate their costs to the environment, Bengt Steen believes their development moves too slowly. There is no standardised framework, and few databases exist that enable their use in a uniform manner.</div> <div> </div> <div>Therefore, in 2015, the idea of a new ISO standard was born within Swedish Life Cycle Center. Together with SIS – the Swedish Standards Institute – a proposal was written that now after just over three years of work, together with many internationally recognised experts, is launched.</div> <div> </div> <div>“Few things yield such an impact as these type of heavyweight, international standards,” explains Bengt Steen. “When companies in the future can see where there are clear environmental benefits, investments are stimulated for a sustainable business.”</div> <div> </div> <div><a href="">The ISO standard</a> contains a guide for how monetary valuation should be made, defines terms and sets requirements for documentation. By extension, the standard is expected to lead to increased collaboration between experts of various kinds, as well as helping to create credible databases and software.</div> <div> </div> <div><strong>How to calculate a monetary valuation of environmental impacts </strong></div> <div>With monetary valuation of environmental impacts, many different aspects are taken into consideration. These can include energy consumption, climate impact, material use and emissions into water, air and soil. During a product’s lifetime, the amount of emissions generated, and amount of resources expended can also be measured. These lead to many demonstrable environmental effects, such as reduced crop yields, lower fish stocks and shortened human life spans, due to floods and heat waves.</div> <div> </div> <div>Finally, using generally accepted sources, such as the OECD's estimate of people's productivity value, and market prices for cereals, fish and meat, the cost of the impact can be ascertained. The end result is a concrete figure, calculated in Euros.</div> <div>In some cases, the figure represents a real incurred cost for the company, in the form of taxation or fees. In other cases, the figure signals possible future economic liabilities, or is simply a sign that the product results in environmental damage that the company wants to avoid.</div> <div> </div> <div><strong>A simple example of environmental impact valuation</strong></div> <div>Imagine a wooden chair, which is worn out and needs to be disposed of. The chair weighs 12 kg. There are two options:</div> <div> </div> <div>1. Throw the chair into a nearby rubbish bin, after which it ends up in landfill.</div> <div>2. Drive the chair to a heating plant 10 km away, where it will be burned, and used for local heating instead of fossil fuels.</div> <div> </div> <div>In the first case, the cost of transport and the landfill is low – 0.40 Euros, and the emissions from the transport are largely negligible. But, the degradation of the wood in the landfill takes place under oxygen-poor conditions, resulting in 4 kg of methane being formed. This leaks into the atmosphere and contributes to the greenhouse effect. The environmental cost of methane emissions has been calculated at EUR 3.80/kg using the EPS methodology. In total, therefore, there is a conventional cost of 0.40 Euros, and an environmental damage cost of 4 X 3.80 = <strong>15.20 Euros.</strong></div> <div> </div> <div>In the second case, the transport costs 5 Euros. The transport gives an emission of 3.8 kg carbon dioxide, but the thermal energy derived from the chair means that 6 kg of coal does not have to be burned for the heating plant to produce the heat needed. This results in a saving of about 20 kg of carbon dioxide emissions, and 6 kg of the finite natural resource, coal. With EPS, the environmental damage cost for carbon dioxide has been calculated at EUR 0.135/kg and the natural resource value of coal at EUR 0.161/kg. Therefore, this method of disposal results in a total conventional cost of 5 Euro, but a saving of environmental damage costs, an actual environmental gain, of 0.135 X (20 - 3.80) + 0.161 X 6 = <strong>3.153 Euros.</strong></div> <div> </div> <div><span><span><strong>Text: Ulrika Georgsson<span style="display:inline-block"></span></strong></span></span><br /></div> <h4 class="chalmersElement-H4">More about: ISO</h4> <div>ISO is an international standardisation body, consisting of national standardisation organisations.

The project abbreviated &quot;Ultimate&quot;, which was coordinated by Chalmers, is now being praised by the EU.</b></p>The project &quot;Ultra Low emission Technology Innovations for Mid-century Aircraft Turbine Engines&quot;, abbreviated &quot;Ultimate&quot; has been running for three years targeted radical concepts for new aero engines, in line with the EU’s long-term emissions reduction target for 2050.  The EU is highlighting the project as a success.  <h5 class="chalmersElement-H5">Could save 3 billion tonnes of CO2 emissions over the first 20 years after 2050 </h5> <div>To address this challenge, the ULTIMATE project has developed radical new propulsion concepts that should help the aviation industry meet the targets. The partners have studied how different technologies could be combined to work together in synergy to improve efficiency and reduce emissions. If fully implemented, the engine concepts proposed by the ULTIMATE project could save 3 billion tonnes of CO2 emissions over the first 20 years after 2050. <img src="/SiteCollectionImages/Institutioner/M2/Nyheter/tgartikel.jpg" class="chalmersPosition-FloatRight" alt="Tomas Grönstedt" style="margin:5px;width:200px;height:300px" /><br /><br /></div> <div>“The technologies combined in our new engine systems benefit one another.

Next, the project team made system models and based on efficiency estimates for each component, they were able to accurately predict how new and existing engine system components would interact and optimise the engine performance cycles. These new jet engines could dramatically improve aircraft efficiency and reduce emissions. They may also be used in novel aircraft designs, with new fuels such as biofuels, hydrogen or methane, and together with turboelectric systems. </div> <h5 class="chalmersElement-H5">Radical engine concepts work </h5> <div>Grönstedt emphasises the importance of the project outcomes: “Radical improvements to aviation will only happen if the engineering community believes they are possible. Engineers don’t like to introduce unnecessary technical risk and they need to know that improvements can be made economically. The ULTIMATE project has indicated that such engines are feasible, which will help to increase confidence in these radical concepts.” </div> <h5 class="chalmersElement-H5">Read more </h5> <div><a href="">EU Research Success Story - Synergistic jet engines for cleaner aviation  </a></div> <div><a href="/en/departments/m2/news/Pages/The-EU-commits-to-research-into-ultra-efficient-aero-engines.aspx">The EU commits to research into ultra-efficient aero engines </a></div>Fri, 08 Mar 2019 11:00:00 +0100,-drinking-water,-and-marine-technology-–-2019s-honorary-doctorates.aspx,-drinking-water,-and-marine-technology-%E2%80%93-2019s-honorary-doctorates.aspxPlants, drinking water, and marine technology – 2019&#39;s honorary doctorates<p><b>​Three researchers have been awarded honorary doctorates at Chalmers for 2019.
