In processes such as photosynthesis and many types of catalysis, charge transfer reactions between metal ions and their surroundings, and the time scale on which they occur, play a major role. Jakob Andreasson, guest researcher at the Condensed Matter Physics division at Chalmers University of Technology, has together with an International and interdisciplinary team of researchers performed a study where a combination of ultrashort X-ray and laser pulses were used to show how the local binding of copper ions depends on the speed of charge transfer in photochemical reactions. The results of this demanding series of experiments were published earlier this week in Nature Chemistry.</p> <p class="chalmersElement-P">The research project is led by Sonja Herres-Pawlis from the RWTH Aachen University (RWTH),  Michael Rübhausen from the University of Hamburg and Wolfgang Zinth from Munich’s Ludwig Maximilian University.</p> <p class="chalmersElement-P"><a href="">Read the press release from DESY</a><br /></p> <div> </div> <div><a href="">Read the article in Nature Chemistry<br /></a></div> <div>doi:10.1038/nchem.2916</div> <div><br /> </div> <div><p class="chalmersElement-P"><em>Photo: Jakob Andreasson during preparations for an experiment at the AMO instrument at the X-ray Free Electron Laser LCLS at SLAC, Stanford, California. </em>(Jakob Andreasson, private)</p> <div><a href=""></a> </div></div>Fri, 19 Jan 2018 11:00:00 +0100 charge of the largest battery research network in Europe<p><b>​​Patrik Johansson, Professor at the Department of Physics at Chalmers, has been elected new co-director of a large European battery research network – Alistore European Research Institute (Alistore-ERI).</b></p><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Patrik_Johansson200x270.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />The network is the largest academic-industrial collaboration on batteries in Europe and aims to tackle battery challenges and move towards sustainable energy solutions. The network has about 25 partners, with academic entities such as Cambridge, Oxford and Collège de France, and Bosch, Saft,  BASF and Renault on the industry side.<p></p> “Due to the current electromobility (r)evolution and the need to efficiently store renewable energy, Alistore-ERI is more important than ever before. As researchers, we create projects and share ideas within the network and get important feedback from other academics and the industrial partners,” says Patrik Johansson, who takes part in several national and international projects to develop the next generation of batteries.<p></p> Patrik Johansson will mainly be responsible for strategies for expansion of the network, to increase the internal and external interactions, as well as taking part in defining the research strategy. <p></p> “My role will be to build an even stronger network for future challenges – an inspiring task with many openings for Swedish industry as well,” says Patrik Johansson. <p></p> He will officially start his new assignment on 1st of January and will share the direction with Prof. Christian Masquelier from France and Dr. Robert Dominko from Slovenia. <p></p> Text: Mia Halleröd Palmgren, <a href=""></a><br /><br /><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more about Alistore-European Research Institute (Alistore-ERI).</a><br /><a href="/en/Staff/Pages/Patrik-Johansson0603-6580.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about Patrik Johansson and his research at Chalmers University of Technology.</a><br />Thu, 14 Dec 2017 00:00:00 +0100,-cheap-to-produce-and-easy-to-transport,-new-Wallenberg-Academy-Fellow-project.aspx,-cheap-to-produce-and-easy-to-transport,-new-Wallenberg-Academy-Fellow-project.aspxPolymer solar cells, new Wallenberg Academy Fellow project<p><b>Solar cells are predicted to play an important role in reaching a sustainable energy production, but a problem with the silicon based is their complicated manufacture process. Associate Professor Ergang Wang receives funding as a Wallenberg Academy Fellow to develop polymer solar cells that are bendable and easy to produce.</b></p><div><div>Organic solar cells, OSCs, normally consist a polymer as donor and a fullerene derivative as acceptor in the active layer. However, the fullerene derivate, which is the most common acceptor, cannot guarantee high enough efficiency and stability of OSCs to change the solar power market. As a Wallenberg Academy Fellow <a href="/sv/personal/Sidor/ergang.aspx">Ergang Wang </a>will explore another, fullerene-free path for the OSC. </div> <blockquote dir="ltr" style="font-size:14px;margin-right:0px"><div style="font-size:14px"><span style="font-size:14px">“This fellowship gives me freedom to explore the fields where I believe a solution may exist. It is of course an honour to become a Wallenberg Academy Fellow and a great feeling to finally get it. You should never give up!” he says.</span></div></blockquote> <div>OSCs have the advantages of light-weight, low cost and fast high-volume production. They are also believed to have little environmental impact. Due to the promise of OSCs, many countries have invested heavily in the research and development of OSCs with the aim of commercializing them. As a result, the development of OSCs has been significant with efficiencies improving from 1 percent to over 14 percent in the last two decades. Still the technology is not yet ready for practical applications.</div> <div><br />Fullerenes are football shaped molecules that have many good characteristics in many applications. In many OSCs of today they are used as acceptors in the cell’s active layer. The problem, however, is low stability caused by molecular diffusion, weak absorption in solar spectrum region, high cost and high-energy consumption required to produce fullerene derivatives themselves. Therefore, in order to boost the efficiency and stability of OSCs, there is a strong need to replace fullerenes as the acceptors in OSCs.</div> <blockquote dir="ltr" style="font-size:14px;margin-right:0px"><div style="font-size:14px"><span style="font-size:14px">“For long researchers have tried to improve the fullerenes to be optimised for the OSCs. I want to try a different path. I want my OSCs to be independent from the limitations of fullerenes,” says Ergang Wang.</span></div></blockquote> <div>Ergang Wang and his group have already come far in the development of solar cells only consisting of polymers in the active layer. They have reached an efficiency of nine percent with a blend based on three polymers. They are very light and easy to produce in big roll-to-roll printing machines, kind of like the ones than newspapers are produced in. The major issue now is to get a better stability and efficiency.</div> <blockquote dir="ltr" style="font-size:14px;margin-right:0px"><div style="font-size:14px"><span style="font-size:14px">“I believe that we are on the right track and my vision is that we, because of the funding, may be able to create a prototype with the right efficiency and stability to be able to start collaborations with industry.”</span></div></blockquote> <div>Ergang Wang thinks there is a great interest for breakthroughs in this kind of technology since it is sustainable both ecologically and economically. His goal is to reach towards an efficiency of around fifteen percent, which is a figure he says may make OSCs profitable and competitive in the market. </div> <blockquote dir="ltr" style="font-size:14px;margin-right:0px"><div style="font-size:14px"><span style="font-size:14px">“The silicon cells will be more efficient for a long time forward but OSCs will be more cost effective in the long run.

The seminar brings together world-leading researchers from several science disciplines to present the latest advances within the field.</b></p>​ <br />The conference gathers distinguished researchers, industry representatives, decision makers and an engaged public for presentations and discussions on future energy solutions. Development of sustainable technologies for solar energy, batteries and energy storage is needed to make the necessary switch from fossil fuels to renewable energy sources. During the conference, the latest advances in the field will be highlighted, and the content will be made available to the public. Through live broadcast at <a href="" target="_blank">Molecular Frontiers YouTube Channel</a>  you will be able to follow the conference even if you are not in place. <br /><br /><br /><strong>150 high school students participate</strong><br />Sustainable Energy Symposium is a unique event in several ways – about half of the conference participants are high school students. This is possible thanks to the Molecular Frontiers Foundation which offers a scholarship for students from all over the country to come. The Molecular Frontiers emphasize in particular the importance of being curious and asking good questions. Approximately 150 students from all over the country are given the opportunity to listen to and ask questions to world-leading researchers.<br /><br /><br />Among the speakers are noted:<br /><br /><strong>Steven Chu, Nobel Prize winner in Physics 1997 and Obama's Energy Ministers 2009-2013.</strong><br />Steven Chu was awarded the Nobel Prize in Physics in 1997 for his work on laser cooling of atoms. Since then, his research has increasingly been about solving the challenges of climate change and sustainable energy supply. In 2009, Barack Obama appointed him the United States Secretary of Energy, and became the first scientist in an American government. After his time as Energy Secretary, he returned to research but remains a prominent debater focusing on renewable energy and nuclear power. He emphasizes the importance of reducing fossil fuel use to address global warming and climate change. He has put forward a number of innovative and sometimes controversial proposals for action.<br /><br /><strong>Paul Alivisatos, University of California at Berkeley</strong><br />Paul Alivisatos is a pioneer in nanotechnology, focusing on inorganic nanocrystals. By controlling the size and surface of the nanocrystals, his research team can tailor their properties and produce materials for a variety of applications, including solar cells and materials to reduce carbon dioxide into hydrocarbons. He has developed quantum dots, small semiconductors that are isolated from the environment and are extremely effective in absorbing and transmitting light. These are already used in the most energy efficient and high quality television screens in market today.<br /><br /><strong>Daniel Nocera, Harvard University</strong><br />Two inventions of Daniel Nocera may be of great importance in the future. The artificial leaf, mentioned in Time magazine’s list of Inventions of the Year 2011, mimics the photosynthesis, and splits water into hydrogen and oxygen by using sunlight. A further development of the concept is the bionic leaf, which takes carbon dioxide from the air and combines it with hydrogen from the artificial leaf to produce biomass and liquid fuel. In this way, a cycle is achieved that is much more efficient than photosynthesis in nature, which can contribute to a green and cheap production of fuel and food.<br /><br /><br /><strong>Program</strong><br /><a href="/en/conference/sustainableenergy/Documents/Program_Sustainable_Energy.pdf" target="_blank">Here you will find the entire program for the conference &gt;</a><br /><br /><br />Plenary lectures 7-8 December:<br />• <strong>Steven Chu</strong> – <em>Climate Change and innovative paths to a sustainable future</em><br />Nobel laureate in Physics 1997, former United States Secretary of Energy.

Tao’s visit is funded by the Fulbright programme since he was awarded the prestigious Fulbright Distinguished Chair in Alternative Energy Technology. One of his tasks will be to contribute to the research in <a href="/en/centres/ccr/Pages/default.aspx">Competence Centre Recycling (CCR) </a>with his knowledge in solar cell technology and recycling. He is interested in solar cells from a holistic point of view with the goal set on making the solar cell the prime energy source of the future. <blockquote dir="ltr" style="font-size:14px;margin-right:0px"><div style="font-size:14px"><span style="font-size:14px">- I look holistically at the obstacles that stop solar cells from really reaching a meaningful scale.

I therefore focus on these areas, says Meng Tao. </span></div></blockquote> <div>If you calculate how many solar cells it takes to produce the amount of energy needed to cover the global demands ther<img class="chalmersPosition-FloatRight" src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/Meng%20Tao%20vid%20solceller_340.jpg" width="340" height="305" alt="" style="height:239px;width:265px;margin:5px" />e is still not enough silver, which is an important metal as an electrode in most solar cells, for this to happen, according to Tao. In addition to making solar cells more efficient he believes in finding a way to replace silver with, for example, aluminium. Furthermore, terawatt-scale production of solar cells would take around half of the world’s electricity production of today, which would not be sustainable. Thirdly, for solar cells to really become a sustainable alternative they have to be recyclable. Meng Tao wants to collaborate with Chalmers to remove these and other obstacles by combining the research on recycling methods for solar cell materials that is being carried out at Chalmers and at his home university. </div> <div><br />He will be positioned at the Department of Chemistry and Chemical Engineering, but he is interested in research from all over Chalmers. </div> <blockquote dir="ltr" style="margin-right:0px"><div><span style="font-size:14px">- One of the reasons I came to Chalmers is for the competence in recycling research that can be found in CCR, but I also look forward to getting to know more about the energy research that is going on here and also about the projects around electric vehicles that are conducted at the Swedish Electromobility Centre.

This research will benefit from Meng Tao’s experience. The mutual exchange will be that we have been working on different kinds of solar cells, and may therefor conduct comparative studies and system studies for solar power and energy storing and the material streams, she says.</span></div></blockquote> <div>She also sees possibilities for interesting collaborations with Meng Tao’s home university and expanding Chalmers’ network with other interesting researchers in materials recycling and solar cell materials.<br />Meng Tao’s choice to come to Chalmers is, to Britt-Marie Steenari, a very good thing, but not so surprising.</div> <blockquote dir="ltr" style="margin-right:0px"><div><span style="font-size:14px">- Chalmers was early in seeing materials recycling as a necessary research area. Now it has happened. Many research groups are working with recycling research and development of processes, but the Chalmers Industrial Materials Recycling group is still one of the leading ones in that area. We often get invitations from other universities to participate in materials recycling projects. Chalmers not only host the chemical parts of recycling research, but also production technology, systems analysis, economics and organisation, and all that is needed for a well-functioning and sustainable recycling system. You find all this and more at Chalmers, she says. </span></div></blockquote> <div>The strong research group in materials recycling that exists today at Chalmers is based on the initiative and donation from Stena Metall in 2007, which made way for the international impact of today and led to the collaboration with Meng Tao.

We can see how they store, produce and use energy. A fantastic thing is that we can even make experiments in the microscopes. That makes it possible to optimize materials and improve the effects on our health and environment. The new technique paves the way for sustainable and smart products”, says Eva Olsson, Professor at the Department of Physics at Chalmers University of Technology, and a driving force within the Area of advance for material science. </div> <div> </div> <div>Chalmers has invested in three state of the art electron microscopes for soft matter. Two of them have arrived recently and the third one will be delivered at the end of the year. In total, the equipment costs about 6,9 million euros, of which half the amount was sponsored by Knut and Alice Wallenberg Foundation. </div> <div> </div> <div>Hopefully, the new technique will promote the field of material science and result in better products and fabrication processes in the industry. For example, it can be used to develop functional food and to improve pharmaceuticals, medical implants or solar cells. By designing the microstructure in a better way, it could also be possible to manufacture pulp and paper products in a more environmentally friendly way. </div> <div> </div> <div>To implement the new possibilities, Chalmers invites the industry to different collaborations. On the 5th of May, the first workshop with the new microscopes was arranged. Soft Microscopy Centre hosted the event. The centre is a cooperation between Chalmers’ area of advance Material Science and Research Institutes of Sweden (RISE). The aim is to create opportunities for smart materials for the future and to promote collaborations between academia and the industry. </div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/F/340x296px/Eva_Olsson340x296_NY_IMG_0210.MiaHallerodPalmgrenJPG.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />“I’m proud that we can develop smart materials that contribute to a more sustainable society.

It can reveal the structure of smaller objects and makes it possible to study single atoms. A soft electron microscope is based on the same method, but the energy of the electrons is lower. That makes it possible to study soft organic materials, such as food, textiles or tissues, without destroying the structure of the material. There are different kinds of electron microscopes, for example transmission electron microscopes (TEM), scanning transmission electron microscopes (STEM), scanning electron microscope (SEM) and a combinations of focused ion beam microscope and SEM (FIB-SEM). </div> <div> </div> <h4 class="chalmersElement-H4">Soft microscopy workshop at Chalmers:</h4> <div>On the 5th of May,<a href="/en/areas-of-advance/materials/research/smc/Pages/default.aspx"> Soft Microscopy Centre</a> hosted an industrial workshop aimed for industrial scientists, specialists, and research managers, and academic scientists with an interest in applied science and soft microscopy.

The process is based on the organic compound norbornadiene that upon exposure to light converts into quadricyclane.</div> <div><br /></div> <div>‘The technique means that that we can store the solar energy in chemical bonds and release the energy as heat whenever we need it.’ says <a href="/en/staff/Pages/kasper-moth-poulsen.aspx">Professor Kasper Moth-Poulsen</a>, who is leading the research team. ‘Combining the chemical energy storage with water heating solar panels enables a conversion of more than 80 percent of the incoming sunlight.’</div> <div><br /></div> <div>The research project was initiated at Chalmers more than six years ago and the research team contributed in 2013 to a first conceptual demonstration.
