Researchers at Chalmers have developed a crash test dummy that now sets a new, life-saving standard for safety in passenger cars.</b></p>​​Having the misfortune to be in a car accident in a new and modern car is considerably safer compared to 30 years ago. The main driving force behind the increased safety has been the so-called<em> New Car Assessment Programs </em>(NCAP), which set a new standard for crash safety throughout the world. When the tests were launched in the early 1990s, they received a lot of media attention, which lead to more and more investments in safety by car manufacturers. For car manufacturers performing well in the tests became, and continues to be, one of the most important marketing arguments. <div><br /></div> <div>For some time, crash safety improved mainly for the types of collisions that were represented in the official crash tests, especially for car companies that previously had a low level of ambition in their safety work. However, the risk of injury was still high in accidents where the body was thrown forward in oblique positions, such as in frontal collisions with oblique force direction. “We wanted to contribute to a new test standard for oblique collisions. The dummy used previously turned out to be too rigid and did not give a fair representation of how an actual person reacts to a crash that throws the body forward obliquely”, says Mats Svensson, professor at the Department of Mechanics and Maritime Sciences.</div> <div><h2 class="chalmersElement-H2"><span>An impo</span><span>rtant research tool</span><span> </span></h2></div> <div>To find out how a person moves and is affected by the safety belt in a collision, researchers from Chalmers compiled results from earlier studies and supplemented it with own mobility tests of the shoulder part of test subjects. In this way, the researchers could see how a human shoulder moves and compare it with the standard dummy, which was used for crash tests. It then became evident that the greatest shortcoming of the crash dummy was the difference in the more extensive and complex motion range of the human shoulder.</div> <div><br /></div> <div> With the support of Volvo Cars and Autoliv, the Chalmers researchers developed an artificial shoulder for the crash dummy that could better mimic the human shoulder’s mobility in interaction with the three-point belt in oblique collisions. The design of the dummy is a key factor in the development and evaluation of new safety belts and airbags. “The new type of artificial shoulder was an important research tool for us at Volvo Cars, which makes it possible for us to gain a better understanding of the human body's movement and the car's protective function in collisions with oblique forward movements. Our accident follow-up shows that oblique collisions are common in traffic and have significance for the damage outcome”, says Lotta Jakobsson, Senior Technical Leader Safety at Volvo Cars and adjunct professor at mechanics and maritime sciences. </div> <div><h2 class="chalmersElement-H2"><span>NCAP next step </span></h2></div> <div>Chalmers has participated in the further development of the artificial shoulder and the new crash test dummy, which has resulted in that now both Euro NCAP and US NCAP has the ambition to use the new dummy in future standardized collision tests of new cars. Johan Davidsson is an associate professor at the Department of Mechanics and Maritime Sciences has been Chalmers spokesperson in the international forums that evaluated and recommended the new more advanced crash dummy with the new shoulder. “It is now possible to fine-tune and evaluate airbags and seat belts that use the latest sensor technology to tailor the protection in real-time in the event of a collision. We are convinced that we have contributed to a significant future reduction of injuries and deaths in car collisions”, says Johan Davidsson.</div>Wed, 10 Jul 2019 00:00:00 +0200https://www.chalmers.se/en/departments/mc2/news/Pages/He-built-the-optics-for-Swedens-new-research-satellite.aspxhttps://www.chalmers.se/en/departments/mc2/news/Pages/He-built-the-optics-for-Swedens-new-research-satellite.aspxBuilding the optics for new Swedish satellite<p><b>​It is the first Swedish research satellite in 18 years. Next year, MATS will be launched from Vostochny Cosmodrome in Russia. The main instrument on board the satellite is based on a new type of telescope developed in Gothenburg and described in a thesis by Arvid Hammar.</b></p><div><span style="background-color:initial">Arvid Hammar recently defended his thesis as an industrial doctoral student at the Department of Microtechnology and Nanoscience – MC2 – at Chalmers. He has worked at Omnisys Instruments AB and the Terahertz and Millimetre Wave Laboratory and has been part of a team from Gothenburg that developed and built the payload* of MATS (Mesospheric Airglow/Aerosol Tomography and Spectroscopy) – Sweden's new satellite for atmospheric research.</span><br /></div> <div><br /></div> <div>MATS has been developed in collaboration between researchers at Stockholm University, Chalmers and KTH Royal Institute of Technology. From its orbit at 600 kilometers altitude, MATS will be used to study so-called gravity waves* in the atmosphere by detecting formations in clouds in the mesosphere at altitudes between 70 and 110 kilometers. Just like waves in the ocean, gravity waves in the atmosphere give rise to large-scale circulation and are important to study in order to improve current climate models, and to give a better understanding of the atmosphere as a whole. To make measurements on gravity waves, MATS will detect signals from noctilucent clouds in the ultraviolet wavelength range (270-305 nm) as well as emissions from oxygen molecules at infrared wavelengths (754-772 nm). This will be done using six separate image sensors and by combining information from a large number of images, three-dimensional structures and temperature distributions in the atmosphere can be calculated.</div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/BILD_1_sprangskiss_vit_ENG-665px.jpg" alt="Exploded-view of MATS." style="margin:5px" /><br /><em>Exploded-view drawing of MATS showing the different parts of the satellite. Illustration: </em><em>Swedish National Space Agency</em><br /><br /></div> <div>Because the satellite itself was required to be relatively lightweight and compact– maximum 50 kilograms and not larger than a conventional dishwasher, 60×70×85 cubic centimeters (see picture below) – a single telescope had to be used to form images onto the six image sensors. In order to meet the scientific goals, MATS must be able to detect gravity waves with sizes down to 200 meters over a field of view of 250 kilometers in the atmosphere while disturbing signals – stray light – from, for example, the sun, and light from cities is efficiently suppressed.</div> <div>&quot;Combining these requirements in a single instrument is a big challenge that was driving the development of MATS telescope, which was the main focus of my thesis,&quot; says Arvid Hammar.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/BILD_4_storleksreferens_350px.jpg" class="chalmersPosition-FloatRight" alt="MATS compared to a dishwasher." style="margin:5px" />The telescope itself is a so-called off-axis telescope and is the first of its kind to utilize a new design method where linear astigmatism is eliminated to drastically enlarge the field of view while maintaining a high optical resolution. The fact that the field of view can be made larger is the key to a mission like MATS and cannot be done with classical telescope designs. The design utilizes three mirrors made of solid aluminum, which were fabricated using a special lathing process (diamond turning) that provides optical quality for the geometrically complex surfaces without any need for subsequent polishing.</div> <div><br /></div> <div>The development of the payload has been made in a short time and with small resources, which has been a challenge for Arvid Hammar and his colleagues at Omnisys Instruments.</div> <div>&quot;It was therefore of great value to cooperate with Professor Soojong Pak and his group from Kyung Hee University in South Korea who have years of experience with this new telescope technology that is now used for the first time in a real application,&quot; says Arvid Hammar and continues:</div> <div>&quot;We are a small team that has worked with the development of the optical instrument, but at the same time this has enabled us to work in an efficient manner where the expertise has for the most part been found in-house.&quot;</div> <div><br /></div> <div>In addition to design, the development of MATS has also implied extensive testing to ensure a functioning instrument in the challenging environment that space entails. The imaging quality of the telescope has been tested in a newly built lab that Arvid Hammar has set up and been responsible for as part of his work. In addition to optical resolution, stray light suppression has also been measured in the same facility.</div> <div>&quot;By utilizing a new extremely black material based on carbon nanotubes, the throughput of stray light has been minimized,&quot; says Arvid Hammar.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/BILD_3_mats_monterad_350px.jpg" class="chalmersPosition-FloatLeft" alt="Mats mounted." style="margin:5px" />For about two years, MATS will be used to study the upper part of the atmosphere. The data produced will be used by researchers worldwide. The launch is scheduled for 2020 when several satellites are sent up simultaneously using the same rocket, including a larger Canadian satellite. The last time Sweden put a research satellite in space was in 2001 when Odin was launched. During its 18 years in orbit, Odin has traveled nearly 100,000 times around the earth, although it was also expected to last for two years. A copy of the research satellite Odin can be seen close by Café Canyon at MC2. To the left is t<span style="background-color:initial">he research satellite MATS in mounted condition at OHB Sweden in Kista, with visible contributions from Omnisys and Chalmers.</span></div> <div><br /></div> <div>Arvid Hammar defended his research findings related to the MATS telescope in his thesis &quot;Optics for Observation Instruments&quot; on 12 April. The thesis also describes instruments operating at longer wavelengths for two other space-related projects. Professor Jan Stake, head of the Terahertz and Millimetre Wave Laboratory, has been Arvid's main supervisor together with Anders Emrich, technical manager at Omnisys.</div> <div>&quot;It is exciting to see how a solid thesis work can be an important part of a new Swedish research satellite, whose instrument will contribute to a better understanding of our atmosphere and global climate challenges.

The molecule has the unique ability to capture energy from the sun’s rays and release it later as heat. This is shown by researchers at Chalmers University of Technology, Sweden, in the scientific journal Advanced Science.</b></p>​<span style="background-color:initial">On sunny summer days, it can be little short of unbearable to stay indoors or in cars. The heat radiates in and creates an unpleasantly high temperature for people, animals, and plants. Using energy-intensive systems such as air conditioning and fans means combating the thermal energy with other forms of energy. Researchers at Chalmers University of Technology are proposing a method that utilises the heat and distributes it evenly over a longer period instead.</span><div>When their specially designed molecule is struck by the sun’s rays it captures photons and simultaneously changes form – it is isomerised. When the sun stops shining on the window film the molecules release heat for up to eight hours after the sun has set. </div> <div><br /></div> <div>“The aim is to create a pleasant indoor environment even when the sun is at its hottest, without consuming any energy or having to shut ourselves behind blinds. Why not make the most of the energy that we get free of charge instead of trying to fight it,” says chemist Kasper Moth-Poulsen, who is leading the research.</div> <div><br /></div> <div>At dawn when the film has not absorbed any solar energy it is yellow or orange since these colours are the opposite of blue and green, which is the light spectrum that the researchers have chosen to capture from the sun. When the molecule captures solar energy and is isomerised, it loses its colour and then becomes entirely transparent. As long as the sun is shining on the film it captures energy, which means that not as much heat penetrates through the film and into the room. At dusk, when there is less sunlight, heat starts to be released from the film and it gradually returns to its yellow shade and is ready to capture sunlight again the following day. </div> <div><br /></div> <div>“For example, airports and office complexes should be able to reduce their energy consumption while also creating a more pleasant climate with our film, since the current heating and cooling systems often do not keep up with rapid temperature fluctuations,” says Moth-Poulsen. </div> <div><br /></div> <div>The molecule is part of a concept the research team calls MOST, which stands for ‘Molecular Solar Thermal Storage’. Previously the team presented an energy system for houses based on the same molecule (see the related press release below). In that case – after the solar energy had been captured by the molecule – it could be stored for an extended period, such as from summer to winter, and then used to heat an entire house. The researchers realised that they could shorten the step to application by optimising the molecule for a window film as well, which would also create better conditions for the slightly more complex energy system for houses. </div> <div><br /></div> <div>What the researchers still have to do is to increase the concentration of the molecule in the film whilst also retaining the film’s properties, and bring down the price of the molecule. But according to Moth-Poulsen they are very close to this innovation. </div> <div><br /></div> <div>“The step to applying our film is so short that it could happen very soon. We are at a very exciting stage with MOST,” he says.</div> <div><br /></div> <div><strong>More about the research</strong></div> <div><a href="https://onlinelibrary.wiley.com/doi/full/10.1002/advs.201900367">Read the article in the paper Solar Energy Storage by Molecular Norbornadiene–Quadricyclane Photoswitches: Polymer Film Devices</a><br /></div> <div><br /></div> <div>The research has been funded by the Australian Research Council, the Knut and Alice Wallenberg Foundation and the Swedish Strategic Research Foundation.<br /></div> <div><br /></div> <div>For more information, contact:</div> <div>Kasper Moth-Poulsen, Professor of Nanochemistry, Chalmers University of Technology, Sweden, +46 761 99 68 55, kasper.moth-poulsen@chalmers.se</div> Mon, 08 Jul 2019 07:00:00 +0200https://www.chalmers.se/en/news/Pages/Proteins-trapped-in-glass-could-yield-new-medicinal-advances-.aspxhttps://www.chalmers.se/en/news/Pages/Proteins-trapped-in-glass-could-yield-new-medicinal-advances-.aspxUnique method open new doors for medicinal research<p><b>​Researchers at Chalmers University of Technology, Sweden, have developed a unique method for studying proteins which could open new doors for medicinal research. Through capturing proteins in a nano-capsule made of glass, the researchers have been able to create a unique model of proteins in natural environments. The results are published in the scientific journal, Small.</b></p>​<span style="background-color:initial">Proteins are target-seeking and carry out many different tasks necessary to cells’ survival and functions. This makes them interesting for development of new medicines – particularly those proteins which sit in the cellular membrane, and govern which molecules are allowed to enter the cell and which are not. This means that understanding how such proteins work is an important challenge in order to develop more advanced medicines. But this is no easy feat – such proteins are highly complex. Today several different methods are used for imaging proteins, but no method offers a full solution to the challenge of studying individual membrane proteins in their natural environment. </span><div><br /><div>A research group at Chalmers University of Technology, under the leadership of Martin Andersson at the Department of Chemistry and Chemical Engineering, has now successfully used Atom Probe Tomography to image and study proteins. Atom Probe Tomography has existed for a while, but has not previously been used in this way – but instead for investigating metals and other hard materials. </div> <div><br /></div> <div>“It was in connection with a study of contact surfaces between the skeleton and implants when we discovered we could distinguish organic materials in the bone with this technique. That gave us the idea to develop the method further for proteins,” says Martin Andersson. </div> <div><br /></div> <div>The challenge lay in developing a method of keeping the proteins intact in their natural environment. The researchers successfully achieved this by encapsulating the protein in an extremely thin piece of glass, only around 50 nanometres in diameter (a nanometre is 1 millionth of a millimetre.) They then sliced off the outermost layer of the glass using an electrical field, freeing the protein atom by atom. The protein could then be recreated in 3D on a computer. </div> <div><br /></div> <div>The results of the study have been verified through comparison with existing three-dimensional models of known proteins. In the future, the researchers will refine the method to improve the speed and accuracy. </div> <div>The method is ground breaking in several ways. As well as modelling the three-dimensional structure, it also reveals the proteins’ chemical composition. </div> <div><br /></div> <div>“Our method offers a lot of good solutions and can be a strong complement to existing methods. It will be possible to study how proteins are built at an atomic level,” says Martin Andersson. </div> <div><br /></div> <div>With this method, potentially all proteins can be studied, something that is currently not possible. Today, only around one percent of membrane proteins have been successfully structurally analysed. </div> <div>“With this method, we can study individual proteins, as opposed to current methods which study a large number of proteins and then create an average value,” says Gustav Sundell, a researcher in Martin Andersson’s research group. </div> <div><br /></div> <div>With Atom Probe Tomography, information on an atom’s mass can also be derived. </div> <div>“Because we collect information on atoms’ masses in our method, it means we can measure the weight. We can then, for example, create tests where medicinal molecules are combined with different isotopes – giving them different masses – which makes them distinguishable in a study. It should contribute to speeding up processes for constructing and testing new medicines,” says Mats Hulander, a researcher in Martin Andersson’s group. </div> <div><br /></div> <div><strong>Read the article:</strong> <br /><a href="https://onlinelibrary.wiley.com/doi/10.1002/smll.201900316">“Atom Probe Tomography for 3D Structural and Chemical Analysis of Individual Proteins” published in the journal Small.​</a></div> <div><br /></div> <div><strong>Text:</strong> Malin Ulfvarson</div> <div><br /></div> </div>Wed, 03 Jul 2019 10:00:00 +0200https://www.chalmers.se/en/departments/see/news/Pages/current-pledges-to-phase-out-coal-power-are-critically-insufficient-to-slow-down-climate-change,-analysis-shows.aspxhttps://www.chalmers.se/en/departments/see/news/Pages/current-pledges-to-phase-out-coal-power-are-critically-insufficient-to-slow-down-climate-change,-analysis-shows.aspxCurrent coal phase-out pledges are insufficient<p><b>​The Powering Past Coal Alliance, or PPCA, is a coalition of 30 countries and 22 cities and states, that aims to phase out unabated coal power. But analysis led by Chalmers University of Technology, Sweden, published in Nature Climate Change, shows that members mainly pledge to close older plants near the end of their lifetimes, resulting in limited emissions reductions. The research also shows that expansion of the PPCA to major coal consuming countries would face economic and political difficulties.</b></p>​<span style="background-color:initial">By analysing a worldwide database of coal power plants, the researchers have shown that pledges from PPCA members will result in a reduction of about 1.6 gigatonnes of C02 from now until 2050. This represents only around 1/150th of projected C02 emissions over the same time period from all coal power plants which are already operating globally. </span><div><img src="/SiteCollectionImages/20190101-20190630/jessica-jewell_portrait.jpg" class="chalmersPosition-FloatRight" alt="" style="margin-right:10px;height:262px;width:200px" /></div> <div>​<br /><span style="background-color:initial"></span><div>“To keep global warming below 1.5°C, as aimed for in the Paris climate agreement, we need to phase-out unabated coal power – that is, when the carbon emissions are not captured – by the middle of this century. The Powering Past Coal Alliance is a good start but so far, only wealthy countries which don’t use much coal, and some countries which don’t use any coal power, have joined,” says Jessica Jewell, Assistant Professor at the Department of Space, Earth and the Environment at Chalmers University of Technology, and lead researcher on the article. </div> <div><br /></div> <div>To investigate the likelihood of expanding the PPCA, Jessica Jewell and her colleagues compared its current members with countries which are not part of the Alliance. They found that PPCA members are wealthy nations with small electricity demand growth, older power plants and low coal extraction and use. Most strikingly, these countries invariably rank higher in terms of government openness and transparency, with democratically elected politicians, independence from private interests and strong safeguards against corruption</div> <div><br /></div> <div>These characteristics are dramatically different from major coal users such as China, where electricity demand is rapidly growing, coal power plants are young and responsible for a large share of electricity production, and which ranks lower on government transparency and independence. </div> <div><br /></div> <div>The researchers predict therefore, that while countries like Spain, Japan, Germany, and several other smaller European countries may sign up in the near future, countries like China – which alone accounts for about half of all coal power usage worldwide – and India, with expanding electricity sectors and domestic coal mining are unlikely to join the PPCA any time soon. </div> <div><br /></div> <div>And recent developments confirm these predictions. Germany recently announced plans to phase out coal power, which could lead to a further reduction of 1.6 gigatonnes of C02 – a doubling of the PPCA’s reductions. On the other hand, the USA and Australia illustrate the difficulties of managing the coal sector in countries with persistent and powerful mining interests. The recent election in Australia resulted in the victory of a pro-coal candidate, supportive of expanding coal mining and upgrading coal power plants.</div> <div><br /></div> <div>More generally, the research suggests that coal phase-out is feasible when it does not incur large-scale losses, such as closing down newly constructed power plants or coal mines. Moreover, countries need the economic and political capacity to withstand these losses. Germany, for instance, has earmarked 40 billion Euros for compensating affected regions. </div> <div><br /></div> <div>“Not all countries have the resources to make such commitments. It is important to evaluate the costs of and capacities for climate action, to understand the political feasibility of climate targets,” explains Jessica Jewell. </div> <div><br /></div> <div><a href="https://www.nature.com/articles/s41558-019-0509-6" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the study “Prospects for Powering Past Coal” in the journal Nature Climate Change </a></div> <div><a href="https://poweringpastcoal.org/" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more on the Powering Past Coal Alliance here.</a></div> </div>Tue, 02 Jul 2019 08:00:00 +0200https://www.chalmers.se/en/departments/e2/news/Pages/Fast-charging-from-buses-to-boats.aspxhttps://www.chalmers.se/en/departments/e2/news/Pages/Fast-charging-from-buses-to-boats.aspxFast charging to be developed from buses to boats<p><b>​Volvo Penta, ABB and Chalmers University of Technology have initiated a collaboration on possible solutions for fast charging of electrified passenger vehicles in a marine environment.​</b></p>​<span style="background-color:initial">A feasibility study will assess if similar technology used for fast charging of electric buses also could be adapted for charging of electric vessels.

To achieve this, we use incredibly strong laser pulses and electrons with high energy,” says Mattias Marklund, Professor of Physics at the University of Gothenburg.</div> <div><br /></div> <div>The research group also includes Arkady Gonoskov, Assistant Professor at the Department of Physics, University of Gothenburg and Joel Magnusson, PhD-student at the Department of Physics at Chalmers.</div> <div><br /></div> <div>“What’s new about our results is that we have created an optimal configuration of laser pulses, where the laser energy is focused on an extremely small surface. This means that you get as much light as possible in the focus point,” says Joel Magnusson.</div> <div><br /></div> <div>The goal of creating such a forceful collision between laser pulses and electrons is to create photons (light particles) with as high energy as possible. If the research group's theories and simulations are successfully recreated in a lab, it would mean that researchers now have access to light with extremely high energy, known as gamma rays, at a level that has not previously been available. A photon produced according to the proposed experiment would have more than one billion times the energy of visible light.</div> <div><br /></div> <div>“Through this discovery, new areas of physics can be reached, realms of physics that have previously not been available to study. Eventually, we hope that our models will be tested in the newly built ELI laboratory in Prague. The next step will then be to identify how to utilize these new opportunities,” says Arkady Gonoskov.</div> <div><br /></div> <div>The amounts of energy that the proposed experiment would give access to can be compared to the levels found in heavy atomic nuclei – or in astronomical phenomena that have so far only been observed with telescopes.</div> <div><br /></div> <div>“A possible use for these findings is in laboratory astrophysics. The technique could recreate astrophysical conditions in a controlled laboratory environment. This would bring the physics of the stars down to earth,” says Mattias Marklund.<span style="background-color:initial">​</span></div></div> <div><br /></div> <span></span><div></div> <div><span></span><a href="https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.122.254801%E2%80%8B">The results are published in Physical Review Letters.</a> The research has been done in collaboration with Lawrence Berkeley National Laboratory (LBNL) in California, USA, ELI Beamlines in Prague, Czech Republic and Kansai Photon Science Institute in Kyoto, Japan.​<br /></div> <div><span style="background-color:initial"><br /></span></div> <div><span></span><a href="https://news.cision.com/se/goteborgs-universitet/r/ny-laserfysik-uppnar-energi-pa-astronomiska-nivaer%2cc2853281"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release and download hig resolution images. ​​</a></div> <div><br /></div> <div><div><span style="font-weight:700;background-color:initial">Text and photo</span><span style="background-color:initial">: Carolina Svensson, </span><a href="mailto:carolina.svensson@physics.gu.se%E2%80%8B">carolina.svensson@physics.gu.se​​</a><br /></div> <div><span style="font-weight:700">Illustration</span> <span style="background-color:initial">of the extremely powerful light source: </span><span style="background-color:initial">Joel Magnusson​​​​​.​​​</span></div></div> <div><span style="background-color:initial">​<br /></span></div> <div><img src="/SiteCollectionImages/Institutioner/F/750x340/Pressmeddelande%20Arkady%20Mattias%20Joel%202019%20(Cred%20Carolina%20Svensson)750x340.jpg" alt="" style="margin:5px" />The researchers behind the results: <span style="background-color:initial">Arkady Gonoskov, Mattias Marklund and Joel Magnusson. </span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="color:rgb(33, 33, 33);font-family:inherit;font-size:20px;background-color:initial">For more information: </span><br /></div> <div><strong style="background-color:initial"><br /></strong></div> <div><strong style="background-color:initial">Mattias Marklund</strong><span style="background-color:initial">, P</span><span style="background-color:initial">rofessor of Physics, Department of Physics, </span>University of Gothenburg<span style="background-color:initial"><br /></span><span style="background-color:initial">+46 (0)31 786 9127, </span><span style="background-color:initial"><a href="mailto:mattias.marklund@physics.gu.se">mattias.marklund@physics.gu.se</a></span><br /></div> <div><br /></div> <div><strong>Arkady Gonoskov</strong>, <span style="background-color:initial"></span><span style="background-color:initial">Assistant P</span><span style="background-color:initial">rofessor, Department of Physics, University of Gothenburg</span></div> <div><span style="background-color:initial"></span><span style="background-color:initial">+46 70 208 56 94,</span><a href="mailto:%20arkady.gonoskov@physics.gu.se"><span style="background-color:initial"> </span><span style="background-color:initial">arkady.gonoskov@physics.gu.se</span></a></div> <div><br /></div> <div><span style="background-color:initial"><strong>Joel Magnusson,</strong> </span>PhD-student, Department of Physics, Chalmers University of Technology</div> <div><span style="background-color:initial"></span><span style="background-color:initial">+46 (0)31 772 3708</span><span style="background-color:initial">, </span><span style="background-color:initial"><a href="mailto:%20joel.magnusson@chalmers.se"> </a></span><span style="background-color:initial"><a href="mailto:%20joel.magnusson@chalmers.se">joel.magnusson@chalmers.se</a></span></div> <div><br /></div></div> <p class="chalmersElement-P"> </p>Tue, 02 Jul 2019 00:00:00 +0200https://www.chalmers.se/en/departments/tme/news/Pages/Statue-honours-first-woman-in-Sweden-to-become-an-engineer.aspxhttps://www.chalmers.se/en/departments/tme/news/Pages/Statue-honours-first-woman-in-Sweden-to-become-an-engineer.aspxStatue honours first woman in Sweden to become an engineer<p><b>Just over a century ago Vera Sandberg became the first woman in Sweden to receive an engineering degree.

The other two are the author and poet Karin Boye, whose statue is located outside Göteborg City Library, and Johanna Hedén, whose bust is located outside Östra Sjukhuset’s women’s clinic. Hedén was a midwife and the first Swedish woman to receive formal training as a surgeon.</li> <li>‘Veras laboration’ is a bronze statue with lighting and motion, which depicts Vera Sandberg working in a laboratory. The statue is a total of four metres high, including a two metre high pedestal. “I wanted to depict Vera in her working environment, and think that she represents an encounter between the past and the present”, said Cardell during the unveiling.</li> <li>Many alumni and friends of Chalmers have made donations towards the statue, to a value totalling around half a million SEK. The Chalmers University of Technology Foundation has contributed the same amount. The donors include students, relatives of Sandberg, Dan Sten Olsson, alumni such as Rune Andersson (through Mellby Gård) and several companies.</li></ul>Mon, 01 Jul 2019 14:00:00 +0200https://www.chalmers.se/en/departments/chem/news/Pages/Bo-Albinsson-new-member-of-the-Royal-Swedish-Academy-of-Sciences.aspxhttps://www.chalmers.se/en/departments/chem/news/Pages/Bo-Albinsson-new-member-of-the-Royal-Swedish-Academy-of-Sciences.aspxBo Albinsson new member of the Royal Swedish Academy of Sciences<p><b>​Bo Albinsson, Professor of Physical Chemistry at the Department of Chemistry and Chemical Engineering has been elected member of the Royal Swedish Academy of Sciences.</b></p>​<span style="background-color:initial">In his research, Bo Albinsson moves within the entire spectrum of physical chemistry, from experimental molecular spectroscopy to theoretical modeling and quantum mechanical calculations.

Their research could revolutionise the manufacturing of green products. Through emulating the natural cellular architecture of wood, they now present the ability to create green products derived from trees, with unique properties – everything from clothes, packaging, and furniture to healthcare and personal care products.</b></p>​<span style="background-color:initial">The way in which wood grows is controlled by its genetic code, which gives it unique properties in terms of porosity, toughness and torsional strength. But wood has limitations when it comes to processing. Unlike metals and plastics, it cannot be melted and easily reshaped, and instead must be sawn, planed or curved. Processes which do involve conversion, to make products such as paper, card and textiles, destroy the underlying ultrastructure, or architecture of the wood cells. But the new technology now presented allows wood to be, in effect, grown into exactly the shape desired for the final product, through the medium of 3D printing. </span><div><br /><div>By previously converting wood pulp into a nanocellulose gel, researchers at Chalmers had already succeeded in creating a type of ink that could be 3D printed. Now, they present a major progression – successfully interpreting and digitising wood’s genetic code, so that it can instruct a 3D printer.</div> <div><br /></div> <div>It means that now, the arrangement of the cellulose nanofibrils can be precisely controlled during the printing process, to actually replicate the desirable ultrastructure of wood. Being able to manage the orientation and shape means that they can capture those useful properties of natural wood.</div> <div><img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/Mimicking%20the%20ultrastructure%20of%20wood/Paul%20Gatenholm.png" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><span style="background-color:initial">“This is a breakthrough in manufacturing technology. It allows us to move beyond the limits of nature, to create new sustainable, green products. It means that those products which today are already forest-based can now be 3D printed, in a much shorter time. And the metals and plastics currently used in 3D printing can be replaced with a renewable, sustainable alternative,” says Professor Paul Gatenholm, who has led this research within Chalmers University of Technology’s Wallenberg Wood Science Centre.</span><br /></div> <div><br /></div> <div>A further advance on previous research is the addition of hemicellulose, a natural component of plant cells, to the nanocellulose gel. The hemicellulose acts as a glue, giving the cellulose sufficient strength to be useful, in a similar manner to the natural process of lignification, through which cell walls are built.</div> <div><br /></div> <div>The new technology opens up a whole new area of possibilities. Wood-based products could now be designed and ‘grown’ to order – at a vastly reduced timescale compared with natural wood.</div> <div><br /></div> <div>Paul Gatenholm's group has already developed a prototype for an innovative packaging concept. They printed out honeycomb structures, with chambers in between the printed walls, and then managed to encapsulate solid particles inside those chambers. Cellulose has excellent oxygen barrier properties, meaning this could be a promising method for creating airtight packaging for foodstuffs or pharmaceuticals for example.</div> <div>“Manufacturing products in this way could lead to huge savings in terms of resources and harmful emissions,” he says. “Imagine, for example, if we could start printing packaging locally. It would mean an alternative to today's industries, with heavy reliance on plastics and C02-generating transport. Packaging could be designed and manufactured to order without any waste”.</div> <div><br /></div> <div>They have also developed prototypes for healthcare products and clothing.

This ambitious plan aims to both reduce direct emissions and increase involvement in societal climate questions.</b></p>​<span style="background-color:initial">The latest IPCC report from the UN’s climate panel showed that efforts to halt climate change must increase drastically if global warming is to be kept below two degrees. To achieve that climate goal, which Sweden and other countries have signed up to via the Paris agreement, emissions need to be roughly halved every decade. </span><div><br /><span style="background-color:initial"></span><div>That will require rapid changes to society as a whole. All sectors will be influenced. Universities and colleges have several roles to play in this process, including core missions which are now more important than ever:</div> <div><br /> </div> <div><ul><li>​To research climate change – both how to combat it, and how we can adjust to manage it. </li> <li>To educate the citizens and leaders who can carry out the actions required.</li> <li>To develop solutions to reduce greenhouse gas emissions and also remove previously emitted carbon dioxide from the atmosphere. And, to be involved in implementation of those solutions. </li> <li>To spread awareness of new scientific knowledge. </li></ul></div> <div>​<br /></div> <div>For the higher education sector in general, it is these activities that have the biggest potential for contributing meaningful climate action. They are part of the climate framework. </div> <div><br /> </div> <div>But the framework also aims to reduce those climate emissions directly linked to universities’ own operations. One of the biggest factors here is air travel. Tackling this source of carbon dioxide emissions is a challenge for universities, because of the highly international aspect of much of the work. The framework is therefore vital as a collaborative tool, and the signed-up universities and colleges will meet annually to cooperate in this area.</div> <div><br /> </div> <div>The initiative for the climate framework comes from KTH Royal University of Technology and Chalmers </div> <img class="chalmersPosition-FloatRight" alt="Syntolkning: Bild på Chalmers rektor Stefan Bengtsson." src="/SiteCollectionImages/20190101-20190630/StefanBengtsson_190425_07_2.jpg" style="width:189px;height:240px;margin-top:5px;margin-right:10px;margin-bottom:5px" /><div>​University of Technology.</div> <div><br /> </div> <div>“Because reducing emissions is such an urgent need, it is not enough to just focus on technical solutions,” says Chalmers President Stefan Bengtsson. “Behavioural changes are needed too, and this of course affects universities as well. We are some of the country’s largest employers. It is important to show too that we actually take our own research on climate change seriously.”</div> <div><br /> </div> <div>“The higher education sector has a comprehensive responsibility to develop the understanding of climate issues, and their solutions,” says KTH President Sigbritt Karlsson. “To simply pass that responsibility on to coming generations is not good enough.

The signed-up institutions recognise the climate as an essential and high-priority future issue and agree to the following. </div> <div><br /> </div> <div><ul><li>To continue contributing to society in ways such that climate goals can be achieved, through education, research and collaboration. </li> <li>To reduce their own climate impact, and by 2030 have introduced measures to be in line with the 1.5C warming limit.</li> <li>To set up long-term goals for climate work and dedicate resources to achieving those goals and carrying out follow-up measures.</li> <li>To clearly communicate their climate work, to inspire and spread knowledge to other actors and wider society. </li></ul></div> <div><br /> </div> <div>The climate framework is connected to a set of guidelines which describe a number of key areas where the higher education sector can influence society and suggests measures for reducing climate impact. The guidelines can help each university to choose the areas they will work most on, defining the goals and measures required based on their own situation. </div> <h2 class="chalmersElement-H2">More on: the climate measures needed</h2> <div>The latest report from the Intergovernmental Panel on Climate Change, the IPCC, underlined the seriousness of climate change and the urgency with which it needs to be addressed. The report showed that already a warming of 1.5C would result in serious consequences, and that this would markedly increase with a warming of 2 degrees. The current measures to combat climate change, made by various countries, will still lead to a warming of at least 3 degrees this century, with further increases after that. </div> <div><br /> </div> <div>To keep warming below 2 degrees and strive for the 1.5 degree target of the Paris agreement, global emissions will need to reduce by about 50 percent per decade, to reach climate neutrality around the middle of this century. Thereafter, negative emissions need to be achieved. For Sweden, equivalent goals exist through the national climate policy framework. If the reduction in emissions is not fast enough, there is a risk that the climate could pass a critical point where the temperature increase becomes self-reinforcing. </div> <div><br /> </div> <div>Between 2017 and 18 Sweden’s emissions actually increased and no clear reduction in Swedish emissions has occurred since 2014.</div> <div><br /> </div> <div><strong>For more information, please contact: </strong></div> <div><ul><li>​Göran Finnveden, Vice President for Sustainable Development, KTH, +46 8-790 7318, <a href="mailto:goranfi@kth.se">goranfi@kth.se</a> </li> <li>Fredrik Hörstedt, Vice President for Utilisation and Sustainable Development, Chalmers, +46 31-772 43 22, <a href="mailto:fredrik.horstedt@chalmers.se">fredrik.horstedt@chalmers.se</a></li></ul> <div><br /> </div> <div><strong>Text:</strong> Johanna Wilde</div></div> </div>Thu, 27 Jun 2019 00:00:00 +0200https://www.chalmers.se/en/news/Pages/through-australia-entirely-on-solar-power.aspxhttps://www.chalmers.se/en/news/Pages/through-australia-entirely-on-solar-power.aspxThrough Australia entirely on solar power<p><b>​A car that will drive 3,000 km, using the sun as its only energy source.

For five years, research at Chalmers has been underway to build models for energy-efficient data traffic. So far, the researchers have managed to reduce energy consumption to one tenth in specified areas.​</b></p>​​<span style="background-color:initial">We are streaming movies and music, saving our pictures in the cloud, and are constantly connected to all the opportunities that the internet offers. The use of a regular smartphone requires about as much electricity as a refrigerator. However, the charging of the mobile phone only accounts for a negligible part of that energy. The rest of the electricity is not being used at our homes, but in data centres which are housing the data stored in the cloud, and during the transportation of data through fiber-optic cables, sometimes being hundreds of kilometers long.</span><div><br /></div> <div><strong>An immense increase in data traffic</strong></div> <div>The amount of data transported via fiber-optic cables is increasing at an almost unimaginable rate. And so does the energy consumption from the data traffic. If nothing is done about the situation, within ten years, the internet alone will consume more electricity than is globally produced. </div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Ny%20modell%20för%20datatrafik%20sparar%20energi%20på%20internet/peter_andrekson_170112_250px.jpg" class="chalmersPosition-FloatRight" alt="Peter Andrekson" style="margin:5px" />“It is a great challenge for society, and for us as researchers, to solve the equation of how to meet the demand for data capacity and performance, while keeping costs at a reasonable level and minimizing environmental impact. Not least, it requires a completely new way of optimizing the technical systems, says Peter Andrekson, Professor of photonics at Chalmers, who over the past five years has been the leader of a large research project with the aim to build a future model for energy-efficient optical fiber communication.</div> <div><br /></div> <div>The intention of the project has been to locate the dominating energy consumers in the fiber-optic systems, and then to design and build a model that only uses one-tenth as much energy as the existing systems do. To succeed in this, a broad approach has been applied. Three different scientific perspectives have been joined together – optical hardware, electronic hardware and information theory, in order to perform coordination and transfer of data in the best possible way.</div> <div><br /></div> <div><strong>Many small energy thieves</strong></div> <div>Something that, at least to some extent, came as a surprise to the researchers was the fact that there are quite many small energy thieves with the potential of affecting the system – not a few large bottlenecks to tackle.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Ny%20modell%20för%20datatrafik%20sparar%20energi%20på%20internet/ErikAgrell_170608_250px.jpg" class="chalmersPosition-FloatLeft" alt="Erik Agrell" style="margin:5px" />“Examples of such energy thieves are the signal processors in the transmitters and receivers in the optical systems”, says Erik Agrell, Professor of communication systems, who in this project has been responsible for developing mathematical models for designing new, more efficient types of transmitter and receiver algorithms. “Higher data transfer rates are requiring transmitters and receivers with the ability to handle stronger signals. However, with the help of error correcting codes, the requirements on the optical hardware can be partially lowered. On the other hand, it also consumes more energy, because the error correcting electronic hardware also runs on electricity. This is a concrete example of the need to find a balance between performance, cost and energy consumption in order to choose the best solution in every individual case.”</div> <div><br /></div> <div>Within the framework of the project, chips containing error correcting code have been designed at Chalmers and then custom made by a manufacturer in Europe. Thereafter, the chips have been tested to verify that the theoretical models and simulations of the power consumption are correct, also in practice. The design and testing have been conducted by researchers in Professor Per Larsson-Edefors' research group at the department of Computer Science and Engineering at Chalmers.​</div> <div><br /></div> <div><strong>Aims at reducing energy consumption to one tenth</strong></div> <div>The prerequisites for how to design the optimal system differ, among other things, depending on the distance that data is being transported. On one hand, the researchers have studied data communication over short distances, from 1 up to 500 meters, which occur, for example, in data centres and in network-based computation clusters. On the other hand, research has also been focused on larger optical systems, where traffic from many users simultaneously travel over distances up to hundreds of kilometers.</div> <div><br /></div> <div>The project aim, to reduce energy consumption to one tenth compared to the models used today, seemed in advance to be quite tough.</div> <div><br /></div> <div>&quot;Within defined areas, we are able to state – not without pride – that we have managed to reach the levels that we aimed for,&quot; says Peter Andrekson. “This applies not least to the power reduction thanks to the error correcting code. We have also received good feedback on the scientific results that we have presented. However, commercial companies are not particularly willing to contribute to this type of research. For competitive reasons, they keep their knowledge to themselves but on the other hand they don´t hesitate to apply the results from academia.”</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Ny%20modell%20för%20datatrafik%20sparar%20energi%20på%20internet/Erik-Agrell-1_500px.jpg" class="chalmersPosition-FloatLeft" alt="Cristian Bogdan Czegledi and Erik Agrell" style="margin:5px" /><em>Professor Erik Agrell (to the right) is discussing effects of polarization in fiber optical communication with the doctoral student Cristian Bogdan Czegledi. (Photo J-O Yxell)​</em><br /><br /><br /></div> <div><strong>Interdisciplinary approach</strong></div> <div>To present results that really optimize the system as a whole, and not just the constituent parts, the researchers have worked interdisciplinary across three research fields. In total, the project will result in five doctoral theses. The doctoral students have worked in pairs circulating across departmental borders – an approach that has been the basis for reaching research results in a broad perspective.</div> <div><br /></div> <div>“To be honest, the process of fully understanding each other's concepts within the project has been time-consuming. Even though we work within related fields of research, there are cultural differences between our specialist areas. Chalmers has a strength in the competence center <a href="/en/centres/force/Pages/default.aspx">FORCE​</a>, which coordinates research on fiber-optical communication”, says Peter Andrekson, who is also the director of this centre. ”We are now expanding, thanks to the move of the research group Optical Networks to Chalmers from KTH in Stockholm.”</div> <div><br /></div> <div><strong>Sustainable economizing of the internet</strong></div> <div>“To obtain an internet that is sustainable from a resource-based point of view, three different perspectives have to be applied, says Erik Agrell. Firstly, it is about developing and using communication technology that is energy efficient, and in this perspective we can contribute as researchers. Secondly, it is about raising awareness and creating incentives for every one of us as internet users not to be unnecessarily wasteful of data traffic. In this case, the individual person, as well as the society at large, and our politicians, have a shared responsibility to maintain sustainability. And lastly, it is important for the climate which energy sources are used in each country to produce the electricity – the less fossil fuels and the more renewables the better.</div> <div><br /></div> <div>“I am convinced that we are moving towards a paradigm shift”, he concludes. “In a not-too-distant future, data transfer and heavy calculations on the internet will be seen as resources to economize with, not as free and unlimited assets.”</div> <div><br /></div> <div><div><strong>More about the research</strong></div> <div>The research has been funded by the Knut and Alice Wallenberg Foundation during five years starting from 2014, with 33,9 MSEK.</div> <div><a href="https://research.chalmers.se/en/project/?id=5914" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Energy-efficient optical fibre communication</a></div> <div><br /></div> <div><strong>For more information, contact:</strong></div> <div><a href="/en/Staff/Pages/Peter-Andrekson.aspx">Peter Andrekson</a>, Professor of photonics, Department of Microtechnology and Nanoscience, Chalmers University of Technology, <a href="mailto:%20peter.andrekson@chalmers.se">peter.andrekson@chalmers.se</a></div> <div><a href="/en/staff/Pages/erik-agrell.aspx">Erik Agrell​</a>, Professor of communication systems, Department of Electrical Engineering, Chalmers University of Technology, <div style="display:inline !important"><a href="mailto:%20agrell@chalmers.se">agrell@chalmers.se</a></div></div> <div><br /></div> <div><div>Text: Yvonne Jonsson</div> <div>Photo: J-O Yxcell (photo at the top of the page), Henrik Sandsjö (portrait photo of Peter Andrekson) and Oscar Mattsson (portrait photo of Erik Agrell)</div></div> <div><br /></div> <a href="mailto:%20agrell@chalmers.se"></a><div><br /></div> <div><strong style="background-color:initial">Data traffic and storage on the internet – this is how it works</strong><br /></div> <div>The internet is largely made up of fiber-optic cables, which are built into our houses, buried in the ground and at the bottom of the sea. In these cables, light is passed through the bundles of optical fibers with cores of very clean glass or plastic. The diameter of the fibers can range from a few millimeters down to less than a strand of hair, and they can be very long. A transmitter sends coded light signals through the optical fibers using lasers or light emitting diodes. At the other end, a receiver obtains the light signals and translates them back into electrical pulses, which are then passed on to computers, TV sets or mobiles. When the fiber-optical system is extended over long distances, signal amplifiers between the transmitter and the receiver may also be needed.</div> <div>When we use internet-based cloud services, we get access to applications, data storage and server capacity via the internet instead of having to handle them locally. Our data is then stored in huge server halls.
