News: Global related to Chalmers University of TechnologyTue, 21 Nov 2017 19:52:12 +0100 fruitful collaboration between medicine and engineering<p><b>​The initiative seminar Engineering Health – The Legacy of William Chalmers on 8-9 November 2017 gathered a large number of engineers and clinicians with one strong interest in common: to bring medicine and engineering closer together.</b></p>​The programme stretched from the past, to the present and into future challenges. Many short pair-presentations provided an overview of ongoing collaborations. These featured local, as well as international, researchers who have succeeded in establishing translational activities.There were a lot of evidence shown on how academia, industry and health care jointly collaborate for mutual progress, for the benefit of patients. Round table discussions and other activities provided plenty of networking opportunities.<br /><br />The initiative seminar was a collaboration between Sahlgrenska University hospital, AstraZeneca, Chalmers, University of Gothenburg and MedTech West. The first day was held at Chalmers and the following day took place at AstraZeneca in Mölndal.<br /><br />Here is a cavalcade of photos from the seminar day at Chalmers 8 November:<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/EngineeringHealth_171108_07_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />The opening of the seminar was held by Stefan Bengtsson, President of Chalmers, and Ann-Marie Wennberg, Hospital director of Sahlgrenska. By cutting a blue and yellow double twisted Möbius ribbon lengthwise they got two halves linked together, manifesting the fruitful collaboration between the two partners. Chalmers and Sahlgrenska – a never ending story.<br /><br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/EngineeringHealth_171108_02_600px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px;width:500px;height:340px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />In a historical reenacting Philip Wramsby and Johan Randhem appeared as William Chalmers and Pehr Dubb, giving the audience a humorous insight into how it might have happened when William Chalmers left half of his fortune to a school, nowadays known as Chalmers University of Technology, and the other half to Sahlgrenska hospital. And the rest is history…<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/EngineeringHealth_171108_08_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Kjell Torén from Sahlgrenska gave an overview of historical collaborations between Chalmers and Sahlgrenska. A traffic accident in the 1950s, where a Professor from Chalmers crashed his motorbike into a bus and got a complicated fracture, is said to have had importance for the upgrading of X-ray equipment at Sahlgrenska and also for the further collaboration in medical engineering.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/EngineeringHealth_171108_10_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />A long-distance guest was Chris Cheng from Stanford University, who gave a talk on “Vascular Biomechanics – A collaborative Effort at Stanford” mentioning that a Chalmers alumnus, Hans Wallstén, created one of the earliest and most successful stents – the Wallstent.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6876_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Stents was also the subject in the presentation given by Mårten Falkenberg, Sahlgrenska, and Håkan Nilsson, Chalmers: “Air bubble release and flow-induced forces in stent grafts”. <br />They also clearly pointed out the benefits of collaboration, listed according to their experience. Among Chalmers´ strengths are technologies, physics, mechanical as well as mathematical models, and analysis of results. Sahlgrenska, on the other hand, has expertise in life science problems, offers a clinical testbed and patient feedback, and is prominent in epidemiology.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/EngineeringHealth_171108_22_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Three flagships of medtech research, originating from Gothenburg, presented themselves. First in line was Max Ortiz Catalan from Chalmers, who gave a talk on “The future of bionic limbs: osseointegration and neural control”. In his research, conducted together with Rickard Brånemark, previously at Sahlgrenska but now at University of California, San Francisco, the world´s first mind-controlled arm prosthesis was developed, now regarded by the patient as a body part more than an external device. A coming research project is focused on feedback and doing the same with a leg; neuromuscular control of robotic leg prostheses.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6895_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />“You couldn´t do it without me!” said Sabine Reinfeldt from Chalmers and her colleague Måns Eeg-Olofsson from Sahlgrenska made the same statement: “You couldn´t do it without me!”. They jointly presented their research on “New hearing implant replacing the middle ear”, where functionally deaf patients can gain normal hearing with a Bone Conduction Implant (BCI). <br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/EngineeringHealth_171108_26_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Mikael Elam, Sahlgrenska, and Mikael Persson, Chalmers, are co-inventors of the stroke helmet Strokefinder and share many research projects in the field of traumatic brain injury and stroke. They presented “A Sahlgrenska Chalmers collaborative effort around Stroke and trauma”. <br />They also emphasized the importance of MedTech West as a network and collaborative platform for research, education, development and evaluation of new biomedical concepts and technologies. The focus is on addressing actual clinical needs in collaboration with relevant clinical staff, and to initiate, facilitate and promote increased research collaboration between the health care sector, industry and academia.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6930_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Elin Rønby Pedersen is a member of Google Medical Brain Team and uses brain technology to solve problems in clinical domains. She focuses her research on the human side of deep learning in health and medicine, for example when it comes to adapting deep neural networks to read fundus images. Big data will only be helpful if you understand the context, was one of her conclusions.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6937_red_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Oliver Aalami from Stanford University Hospital gave a talk on how “Apps, Augmented reality and Bio design” can be designed through collaboration between computer science and medicine. For example, smart glasses can be used by surgeons to better get an overview of monitors and screens in the operating room, without taking the eyes off the patient. <br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/EngineeringHealth_171108_04_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />About 270 persons had registered for the first seminar day at Runan, Chalmers.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6943_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Hanns-Ulrich Marschall, Sahlgrenska, and Paul Hockings, Chalmers, presented their collaboration in the TRISTAN project, focusing on “Imaging biomarkers for safer drugs”, especially in the field of assessment of liver toxicity. MRI-models are used to find biomarkers to better predict toxicity in humans in the development of drugs.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6959_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Marta Bally, Chalmers, and Nils Lycke, Sahlgrenska, gave a talk on &quot;Lipid nanoparticles for mucosal vaccine delivery: from physicochemical properties to immune stimulation&quot;. In their research, they have identified that lipid-based nanoparticles are suitable as pharmaceutical carriers. However, the physicochemical profile of an ideal nanoparticle for mucosal vaccine delivery remains to be further investigated.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6988_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><span><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />A garment with integrated sensors, from the smart textiles project “WearIT” was shown by Kristina Malmgren from Sahlgrenska and Leif Sandsjö from MedTech West/University of Borås. <span style="display:inline-block"></span></span><br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6966_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /> <span><span>Kris</span></span><span><span>tina Malmgren <span style="display:inline-block"> explained</span></span></span>.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6972_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />Textiles that monitor your health or measure your movements was the subject also for Nils-Krister Persson, Smart Textiles Technology Lab, and Anja Lund from Chalmers in their presentation “Chalmers Textiles as enabler for Engineering Health”. Amongst other things they defined the differences between medical textiles, medtech textiles and hygiene textiles. The presentation also included information about research on compression sensitive gastro intestinal stents, where a strain-sensing thread can be integrated in the stent to sense both position and amplitude of deformations.<br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6995_500.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />A poster session was arranged and showed even more projects where clinicians and engineers collaborate. <br /><a href="/en/areas-of-advance/lifescience/events/Engineering-Health/Pages/Abstracts.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read the abstracts from the poster session</a><br /><br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Livsvetenskaper/Engineering%20Health%208%20November%202017/DSC_6883_500px.jpg" class="chalmersPosition-FloatLeft" alt="" style="margin:5px" /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />A number of new Sahlgrenska-Chalmers contacts were made during the coffee breaks, lunch and dinner.<br /><br /><a href="/en/areas-of-advance/lifescience/events/Engineering-Health/Pages/default.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about the initiative seminar</a><br /><br /><span>​Text: Yvonne Jonsson<br />Photo: Yen Strandqvist<span style="display:inline-block"></span></span> and Yvonne Jonsson<br /><br />Tue, 21 Nov 2017 09:00:00 +0100 intelligence and autonomy at the AHA Festival<p><b>​Creative machines, dancing robots, artificial intelligence and investigating workshops. The AHA festival at Chalmers gathers researchers, students and artists - and invites the public to investigate the borders between science and art.</b></p><p>​This year, the theme is autonomy and the festival will take place at the Student Union building at Chalmers on 20-22 November. The programme will be filled with public performances, lectures, workshops, exhibitions and seminar conversations. Permeating the festival is the driving force of curiosity and the festival aims to celebrate science as well as art.</p> <p>“It is essential to have different perspectives and competences when facing the challenges in our society. The AHA festival combines different disciplines within both science and art and offers new ways of exploring the world, aiming towards a sustainable society”, says Peter Christensson, one of two project leaders of the AHA festival. </p> <p>The idea of a border-crossing and international event emerged from a poetry evening at Chalmers, and from ongoing artistic research at the Department of Architecture. In 2014 the first AHA festival was arranged at the department and last year the Department of Physics joined the festival. This year the festival is expanding even more and presents a wide range of Chalmers research and thrilling border-crossing activities. </p> <p>“It might not be that well known, but Chalmers rests upon both a scientific and an artistic ground. This is one way of expressing that. The driving force behind all creativity is curiosity and the most essential questions are the ones that you have in mind when you leave the festival”, says Michael Eriksson, project leader of the AHA festival.<br /> <br />Text: Mia Halleröd Palmgren, <a href=""></a></p> <p></p> <h2 class="chalmersElement-H2">Five highlights at this year’s Aha-festival:</h2> <div><strong>Opera, music technology and dancing robots meet across boundaries.</strong><br />Behind Opera Mecatronics are the artists Åsa and Carl Unander-Scharin.<br /></div> <p>20 November 13:00-14:30</p> <p><strong>Can machines think independently and be creative?</strong><br />Chalmers researchers Mikael Kågebäck and Devdatt Dubhashi speak about how artificial intelligence will change our lives.<br />21 November 9:00-10:00</p> <p><strong>Recycle me!

The larger of these involves an investment into machine learning, deep learning and the next generation of AI. This has been termed “eXplainable AI” and involves asking the system how it reached a particular answer, whereby the system can justify its answers and use them in a general situation. The second pathway deals with increasing our understanding of the mathematical principles behind AI.<br /><br />Each of the two branches has resources to recruit 14 senior researchers and 40 research students, where the research students will become members of graduate schools and take specialist courses in relevant fields. The two new graduate schools will coordinate with the graduate school that has already been established within the framework of WASP, where just over 100 research students are currently studying. Both the senior researchers and the research students will be recruited at the universities that are participating in WASP, primarily Chalmers University of Technology, the Royal Institute of Technology, Linköping University and Lund University. Further Swedish universities, however, may also benefit from the research grant.<br /><br /><img src="/SiteCollectionImages/Areas%20of%20Advance/Information%20and%20Communication%20Technology/News%20events/DavidSands_170x220px.jpg" class="chalmersPosition-FloatRight" alt="David Sands" style="margin:5px" />&quot;This expansion of WASP is a fantastic opportunity for Chalmers and Sweden to build on our existing strengths in AI, but also recruit and train the next generation of AI experts,&quot; says David Sands, Chalmers representative in the WASP Program Management Group.<br /><br /><br />The grant also provides SEK 70 million to reinforce computing infrastructure.<br /><br />“This is a unique investment, even in an international perspective. WASP will in this way obtain the resources needed to create the knowledge platform that Sweden requires if it is to continue to hold its position at the forefront of research and remain competitive,” says Mille Millnert, chair of the WASP board.<br /><br />With this extension, WASP will have a budget of SEK 3 billion between now and 2026. At least 250 research students will be educated, at least 75 of them being industry-based research students. This is a powerful investment with connections to many different parts within artificial intelligence, software development and principles of autonomy. The new grant will also enable the recruitment of 46 senior researchers, the construction of demonstrators (arenas in which the research and commercial worlds can meet in concrete projects), investment into computer infrastructure, guest researcher programmes, and international collaboration.<br /><br />For more information about WASP at Chalmers, contact:<br />David Sands, Professor of Information Security, <a href=""></a><br />Mats Viberg, First Vice President with responsibility for research, <a href=""><br /></a><br /><a href="">Read the full press release from Linköping University &gt;</a>Thu, 16 Nov 2017 11:00:00 +0100 awards to Chalmers corrosion chemist<p><b>​Mohsen Esmaily, researcher at the Inorganic Environmental Chemistry Division has recently received two prestigious awards from the Electrochemical Society and Acta Materialia Inc for cutting-edge research in the field of materials and corrosion science.</b></p><p><a href="/en/Staff/Pages/mohsen-esmaily.aspx">​​Mohsen Esmaily</a> is currently employed as postdoctoral research fellow at the Department of Chemistry and Chemical engineering, Division of Energy and Materials at Chalmers University of Technology.

It gave us inventions like the laser and transistor – inventions that underlie the entire information technology that forms today's society.</div> <div> </div> <div> </div> <div> </div> <div>After many years of basic research on strange quantum phenomena such as superposition, entanglement and squeezed states, scientists have learned to control individual quantum systems as individual atoms, electrons and photons. The world record currently stands at 20 qubits, but rapid progress is being made each month. Applications such as extremely fast quantum devices, intercept-proof communications and hyper-sensitive measuring methods are in sight.</div> <div> </div> <div> </div> <div> </div> <div>Therefore, heavy investments in quantum technology are being made throughout the world. The EU launches a ten-year venture of one billion euros in 2019. Even larger programmes exist in North America, Asia and Australia. IT companies like Google, IBM, Intel and Microsoft are also making significant investments. Safe and fast communication is a strong driving force for quantum technology. Already today there are commercial systems that can transmit quantum encryption keys through an unbroken optical fibre over 100 kilometres, although at a relatively low speed.</div> <div> </div> <div> </div> <div> </div> <div>An imminent milestone that scientists are struggling to achieve is to demonstrate quantum supremacy, which means solving a problem beyond reach even for the most powerful future classic computer. This requires at least 50 qubits. This will be done by means of a quantum simulator, a simpler form of quantum computer. Useful applications of quantum simulation are expected within five years. Realizing a functioning programmable quantum computer will take significantly longer.</div> <div> </div> <div> </div> <div> </div> <div>Mankind’s knowledge about the world and our technical advances are limited by what we can measure, and how accurately. Researchers are also learning to use individual particles, such as photons and electrons, as sensors in measurements of force, gravity, electrical fields, etc. With quantum technology, the measuring power is pushed far beyond what was previously possible.</div> <div> </div> <div> </div> <div> </div> <div>See and hear the researchers tell their story in a video on Youtube &gt;&gt;&gt;<br /></div> <div><a href="">The Quantum Revolution</a></div> <div> </div> <div> </div> <div> </div> <div> </div> <div><strong>Read more about central quantum phenomena in the fact sheet &gt;&gt;&gt;</strong> </div> <div> </div> <div><a href="/en/news/Documents/quantum_technology_popdescr_171114_eng.pdf">Quantum technology</a> (pdf, 200 kB)  </div> <div> </div> <div> </div> <div> </div> <div> </div> <div><strong>Contacts:</strong></div> <div> </div> <div>Per Delsing, Professor of Quantum Device Physics at Chalmers University of Technology, +46-31-772 3317,</div> <div> </div> <div>Göran Johansson, Professor of Applied Quantum Physics at Chalmers University of Technology, +46-31-772 3237,</div> <div> </div>Wed, 15 Nov 2017 08:30:00 +0100 autonomous and eco-friendly public transportation into cities<p><b>Sohjoa Baltic is a EU-funded project that aims to facilitate the transition to autonomous and eco-friendly public transport in the cities around the Baltic Sea.

The research is published in Nature Astronomy on 30 October 2017.</b></p>​<span style="background-color:initial">A team of astronomers led by Wouter Vlemmings, Chalmers University of Technology, have used the telescope Alma (Atacama Large Millimetre/Submillimetre Array) to make the sharpest observations yet of a star with the same starting mass as the Sun. The new images show for the first time details on the surface of the red giant W Hydrae, 320 light years distant in the constellation of Hydra, the Water Snake.</span><div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/WHya_colour_solarsystem_72dpi_340x340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />W Hydrae is an example of an AGB (asymptotic giant branch) star. Such stars are cool, bright, old and lose mass via stellar winds. The name derives from their position on the famous Hertzsprung-Russell diagram, which classifies stars according to their brightness and temperature.</div> <div><br /></div> <div>– For us it’s important to study not just what red giants look like, but how they change and how they seed the galaxy with the elements that are the ingredients of life. Using the antennas of Alma in their highest-resolution configuration we can now make the most detailed observations ever of these cool and exciting stars, says Wouter Vlemmings.</div> <div><br /></div> <div>Stars like the Sun evolve over timescales of many billion years. When they reach old age, they puff up and become bigger, cooler and more prone to lose mass in the form of stellar winds. Stars manufacture important elements like carbon and nitrogen. When they reach the red giant stage, these elements are released into space, ready to be used in subsequent generations of new stars.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/WHya_dss_72dpi_340x340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />Alma's images provide the clearest view yet of the surface of a red giant with a similar mass to the Sun. Earlier sharp images have shown details on much more massive, red supergiant stars like Betelgeuse and Antares. </div> <div><br /></div> <div>The observations have also surprised the scientists. The presence of an unexpectedly compact and bright spot provides evidence that the star has surprisingly hot gas in a layer above the star’s surface: a chromosphere. </div> <div><br /></div> <div>– Our measurements of the bright spot suggest there are powerful shock waves in the star’s atmosphere that reach higher temperatures than are predicted by current theoretical models for AGB stars, says Theo Khouri, astronomer at Chalmers and member of the team.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/star_size_comparisons_72dpi_340x148.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />An alternative possibility is at least as surprising: that the star was undergoing a giant flare when the observations were made.</div> <div><br /></div> <div>The scientists are now carrying out new observations, both with Alma and other instruments, to better understand W Hydrae’s surprising atmosphere. Observations like these with Alma’s highest-resolution configuration are challenging, but also rewarding, explains team member Elvire De Beck, also astronomer at Chalmers.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/SEE/Nyheter/alma_dok-1114-cc_72dpi_340x340.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" />– It’s humbling to look at our image of W Hydrae and see its size compared to the orbit of the Earth.

It is the first of its kind, and can extend the use of terahertz technology to applications that will require flexible electronics, such as wireless sensor networks and wearable technology. The results are published in the scientific journal Applied Physics Letters.</b></p>Terahertz radiation has a wide range of uses and can occur in everything from radio astronomy to medicine. The term refers to the electromagnetic waves whose frequencies range from 100 gigahertz to 10 terahertz. Demand for higher bandwidth in wireless communications and depiction for security applications has led to intensified research on systems and components intended for terahertz frequencies.<br /><br />One challenge has long been to enable low weight and cheap applications. However, advances in polymer technology have promoted the development of flexible electronics and enabled the production of high frequency units on flexible substrates.<br /><br />Now, Chalmers researchers Xinxin Yang, Andrei Vorobiev, Andrey Generalov, Michael A. Andersson and Jan Stake have developed the first mechanically flexible and graphene-based terahertz detector in its kind. Thus, paving the way for flexible terahertz electronics.<br /><img src="/SiteCollectionImages/Institutioner/MC2/News/thz_detektor_171017_adj.jpg" width="629" height="435" alt="" style="margin:5px" /><br /><span class="FeaturedImageText"><em>​</em><span><em>With the help of the two-dimensional material graphene, the first flexible terahertz detector has been developed by researchers at Chalmers. Illustration: Boid – Product Design Studio, Gothenburg.</em><br /></span></span><br />The detector has unique features. At room temperature, it detects signals in the frequency range 330 to 500 gigahertz. It is translucent and flexible, and opens to a variety of applications. The technique can be used for imaging in the terahertz area (THz camera), but also for identifying different substances (sensor). It may also be of potential benefit in health care, where terahertz waves can be used to detect cancer. Other areas where the detector could be used are imaging sensors for vehicles or for wireless communications.<br /><br />The unique electronic features of graphene, combined with its flexible nature, make it a promising material to integrate into plastic and fabric, something that will be important building blocks in a future interconnected world. Graphene electronics enables new applications for, among other things, everyday objects, which are commonly referred to as the Internet of Things.<br /><img src="/SiteCollectionImages/Institutioner/MC2/News/detektor_forskarbilder_171030.JPG" alt="" style="margin:5px" /><br /><em>The research group behind the flexible terahertz detector, from the left </em><span><em>Jan Stake, Xinxin Yang, Andrei Vorobiev, Andrey Generalov and Michael A.

It is a feature that makes graphene an attractive building block in fast electronics. The Chalmers researchers' work is therefore an important step forward for graphene in the terahertz area, and a breakthrough for high performance and cheap flexible terahertz technology.<br /><br />The detector drew attention at the EU Tallinn Digital Summit recently, where several important technological innovations made possible by graphene and related materials were on display. At the summit, EU Heads of State and Government gathered to discuss digital innovation and Europe's digital future. The flagship focus was to show what role graphene can play.<br /><br />The research is also part of Xinxin Yang's licentiate seminar, which will be presented at Chalmers on 22 November 2017.<br /><br />The research on the terahertz detector has been funded by the EU Graphene Flagship, the Swedish Foundation for Strategic Research (SSF), and the Knut and Alice Wallenberg Foundation (KAW).<br /><br />Text: Michael Nystås<br />Illustration: Boid – Product Design Studio, Gothenburg<br />Photographs of Jan Stake, Xinxin Yang, Andrei Vorobiev, Andrey Generalov and Michael A.

Exosomes in patients with the disease don’t have the same ability. This discovery by a research collaboration between Chalmers University of Technology and Astrazeneca takes us a step closer to a cure for type 2 diabetes.</b></p>​Proteins are the body’s workhorses, carrying out all the tasks in our cells. A protein is a long chain of amino acids that must be folded into a specific three-dimensional structure to work. Sometimes, however, they behave incorrectly and aggregate – clump together – into long fibres called amyloids, which can cause diseases. It was previously known that type 2 diabetes is caused by a protein aggregating in the pancreas.<br /><br />“What we’ve found is that exosomes secreted by the cells in the pancreas stop that process in healthy people and protect them from type 2 diabetes, while the exosomes of diabetes patients do not,” says Professor Pernilla Wittung Stafshede, who headed the study whose results were recently published in the <a href="">Proceedings of the National Academy of Sciences, PNAS</a>.<br /><br />What we know now is that “healthy” exosomes bind the protein that causes diabetes on the outside, preventing it from aggregating; however, the results do not explain why. We also don’t know if type 2 diabetes is caused by “sick” exosomes or if the disease itself causes them to malfunction.<br /><br />“The next step is to make controlled models of the exosomes, whose membranes contain lipids and proteins, to understand exactly what component affects the diabetes protein. If we can find which lipid or protein in the exosome membrane leads to that effect, and can work out the mechanism, then we’ll have a good target for development of treatment for type 2 diabetes.”<br /><br />The study is actually a part of industrial doctoral student Diana Ribeiro’s thesis work, and a collaboration between Chalmers and Astrazeneca.<br /><br />“She came up with the idea for the project herself,” says Wittung Stafshede, who is also Ribeiro’s academic advisor at Chalmers. “She had done some research on exosomes before and I had read a bit about their potential. It’s a fairly new and unexplored field, and honestly I didn’t think the experiments would work. Diana had access to pancreatic cells through Astrazeneca – something we’d never had access to before – and she conducted the studies very thoroughly, and this led us to our discovery.”<br /><br />This is the first time that Wittung Stafshede has worked with Astrazeneca.<br /><br />“We ought to collaborate more. It’s beneficial to them to understand what molecular experiments we can carry out, and it’s valuable for us to be able to put our research into a wider medical-clinical perspective. In the search for a future cure for type 2 diabetes, it’s also good for us to already be working with a pharmaceutical company.”<br /><br />Read the article in PNAS:<br /><a href="">Extracellular vesicles from human pancreatic islets suppress human islet amyloid polypeptide amyloid formation</a><br /><br />Text: Christian Borg<br />Photo: Anna-Lena LundqvistTue, 24 Oct 2017 10:00:00 +0200 nanoparticle mapping paves the way for better nanotechnology<p><b>​Researchers at Chalmers University of Technology and the Technical University of Denmark have developed a method that makes it possible to map the  individual responses of nanoparticles in different situations and contexts.

But nanoparticles are temperamental personalities. Even when they look the same from a distance, they are obstinately individual when you zoom in to each individual one.</div> <div>Chalmers researchers Svetlana Alekseeva and Christoph Langhammer together with Danish researchers at the Technical University of Denmark have discovered why different polycrystalline nanoparticles behave so distinctly when they come into contact with hydrogen. This knowledge is essential in order to develop better hydrogen detectors, which are expected to play an important role in the safety of hydrogen cars.</div> <div><br />“Our experim<span><img src="/SiteCollectionImages/Institutioner/F/Divisions/Chemical%20Physics/Staff/Sveta.jpg" class="chalmersPosition-FloatRight" width="125" height="161" alt="" style="margin:5px" /><span style="display:inline-block"></span></span>ents clearly showed how the reaction with hydrogen depends on the specifics of the way in which the nanoparticles are constructed. It was surprising to see how strong the correlation was between properties and response – and how well it could be predicted theoretically,” says Alekseeva, a postdoc at the Department of Physics at Chalmers.</div> <div><br />A nanoparticle of a certain material is comprised of a number of smaller grains or crystals. The number of grains and how they are arranged are therefore crucial in determining how the particle reacts in a certain situation or with a certain substance.</div> <div>Alekseeva and her collaborators have produced maps  – effectively virtual portraits – of individual palladium nanoparticles. The images show the grains as a number of fields which are combined into a map. Some particles consist of a large number of grains, others have fewer grains, and the fields border on one another in different ways.</div> <div><br /></div> <div>This new method of characterising nanoparticles is based on a combination of electron microscopy and optical microscopy. The same individuals are examined using both methods and it is possible to monitor their response when they encounter other substances. This therefore makes it possible to map the basic material properties of nanoparticles at an individual level, and see how these correlate with the response of the particles when they interact with their environment.<br />As a result an almost infinite range of possibilities are opened up for further research and for the development of products and nanomaterials which are both technically optimised and safer from an environmental and health perspective.</div> <div>The nanoparticles that have been investigated also operate as sensors in themselves. When they are illuminated, they reveal how they react with other substances, such as various gases or fluids. Langhammer’s research team is currently working on several projects in this area, including some relating to hydrogen detection.</div> <div><br />But knowledge about nanoparticles is needed in a range of different fields in society. These include, for example, in new electronic devices, batteries, fuel cells, catalytic converters, textiles and in chemical engineering and biotechnology. There is still a lot we do not know about how these small particles operate or will come to affect us and the environment in the long term.</div> <div><br /></div> <div><span><img src="/SiteCollectionImages/Institutioner/F/Divisions/Chemical%20Physics/Staff/clangham2.jpg" class="chalmersPosition-FloatRight" width="125" height="162" alt="" style="margin:5px" /></span>“Nanotechnology is developing fast in the world, but so far the research into nanosafety is not happening at the same pace. We therefore need to get a much better grasp of the risks and what distinguishes a hazardous nanoparticle from a non-hazardous one,” says Langhammer, Associate Professor, Department of Physics, Chalmers.</div> <div>“Our work indicates that not everything is what it seems – it’s the details that are crucial. To understand if and why nanoparticles are hazardous to humans, animals or nature, we also need to look at them individually.

The new method is an outcome of a collaboration between Chalmers University of Technology, Institute of Applied Physics and Lobachevsky University in Russia and University of Plymouth in the UK.

It’s an amazing thing that the photons from this source can be of such high energy,” says Mattias Marklund, professor at the Department of Physics at Chalmers. <p></p> The discovery is highly relevant for the future large scale laser facilities that are under development right now. The most intense light source on earth will be produced at such research facilities – as big as football fields. <p></p> “Our concept is already part of the experimental program proposed for one such facility: Exawatt Center for Extreme Light Studies (XCELS) in Russia. We still don’t know where these studies will lead us, but we know that there are yet things to be discovered within nuclear physics, for example new sources of energy. With fundamental studies, you can aim at something and end up discovering something completely different – which is more interesting and important,” says Arkady Gonoskov. <p></p> Text: Mia Halleröd Palmgren, <a href=""></a><p></p> <a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /></a>​ <strong>Read the scientific article</strong> <a href="">Ultrabright GeV Photon Source via Controlled Electromagnetic Cascades in Laser-Dipole Waves</a> in Physical Review X.<p></p> <p><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the press release and download high-resolution images. ​</a></p> <h5 class="chalmersElement-H5">More information: </h5> <p></p> <a href="/en/Staff/Pages/Mattias-Marklund.aspx">Mattias Marklund</a>, Professor, Department of Physics, Chalmers University of Technology, +46 31 772 39 39, <p></p> <p></p> <a href="/en/staff/Pages/arkady-gonoskov.aspx">Arkady Gonoskov</a>, researcher, Department of Physics, Chalmers University of Technology, +46 31 772 62 89,  <p></p> <strong>Further reading:</strong> <a href="">The code behind a breakthrough in plasma physics.</a><p>​ </p>Thu, 19 Oct 2017 08:00:00 +0200 initiative in process engineering at Chalmers<p><b>​In order to provide new opportunities for research in process engineering, the Chalmers University of Technology Foundation invested SEK 32.2 million in new equipment and personnel.

With the Chalmers University of Technology Foundation’s initiative for process engineering, new knowledge and new possibilities will be made to streamline the chemical engineering processes. The investment made it possible for the Department of Chemistry and Chemical Engineering to purchase new powerful magnetic resonance imaging equipment, MRI, which can depict non-optically available processes, enabling analyse in detail of what happens when, for example, chemicals are mixed into pulp or when medicine dissolves in stomach acid. Chalmers is one of a handful of universities in the world with similar MRI equipment, and this now give companies like Alfa Laval, AstraZeneca, Tetra Pak, Valmet, SCA, several new opportunities for collaboration with Chalmers in process engineering. </p> <blockquote dir="ltr" style="font-size:14px;margin-right:0px"><p style="font-size:14px"><span style="font-size:14px">– With the facility, we will be able to contribute to more efficient use of today's process equipment because we will know more about what actually happens inside the device.

The new MRI gives an opportunity to accurately follow the entire process.

More knowledge can lead to better materials, but also better utilization of equipment in the process industry.</p> <blockquote dir="ltr" style="font-size:14px;margin-right:0px"><p style="font-size:14px"><span style="font-size:14px">– The process industry has noticed that it is not enough only to buy new equipment to progress.

The one who finds the smartest method to quickly verify a system becomes highly sought after. Carl-Johan Seger is one of those people.</b></p>​ <br />In 1995, Carl-Johan Seger received a phone call with an offer that would change the direction of his research career at the University of British Columbia. He had only a few days earlier taken up a professor's appointment with so-called tenure, a meriting position.<br />&quot;I started my new position in June 1995 and in September I resigned,&quot; says Carl-Johan Seger, laughing at the memory.<br /><br />The phone call came from the American semiconductor company Intel, who was in great need of his skills.<br />&quot;There was a crisis at Intel. They had just rolled out a new generation of Pentium processors when a serious error in the construction was discovered. The error had escaped Intel's very extensive verification procedures. The final bill landed somewhere in the neighbourhood of 475 million dollar&quot;, he says.<br /><br />The problem was that the traditional verification method did not allow testing of all conceivable values, it could simply not be done within the time frame, even though very extensive verification was carried out.<br /><br /><strong>Mathematical tools for verification</strong><br />Carl-Johan Seger's research is on formal methods, i.e., mathematical tools for analysis and verification of systems. Very useful for verifying hardware – in this case silicon circuits. The tools that Carl-Johan Seger worked with in his research could offer the solution to the precise problems that Intel suffered.<br /><br />&quot;With formal methods, we developed a verification tool that was not only more reliable, we could also perform the verification faster.&quot;<br /><br />As a result, Carl-Johan Seger introduced early formal verification in the development process at Intel. <br />&quot;Early formal verification is extremely important for achieving good results. It is only after we verify that we can know for sure, and can draw conclusions from the work. It is usually said that we learn by our mistakes, and I couldn’t agree more.&quot;<br /><br />At Intel, he created the Forte Formal Verification System, based on his previous research, and the same verification system is still used today, over 20 years later.<br />&quot;If you buy a computer today with an Intel processor, large parts of the processor are verified by this method.&quot;<br /><br /><strong>Return to academia</strong><br />He stayed at Intel for 22 years, and during that time he has published his research with great impact.<br />&quot;It has been fun working in industry, but there is not much long-term research done. In 2006-2007, I was given the opportunity to be a visiting researcher at Oxford&quot;, he says. <br /><br />Perhaps that is where the thoughts of returning to academia took shape? So, when Intel last year announced staff cuts, and launched a retirement package, he took the offer.<br />&quot;Intel's offer turned to those who with x number of years in the company, added with one's own age, summed to the number 75 or higher. And it included me with a 3-month margin.&quot;<br /><br />Carl-Johan Seger is pleased with his choice to return to academia and Chalmers, and the mood is on top during the interview. We wonder, of course, how he experiences the transition.<br />&quot;It's a big change, I cannot say it's neither better nor worse, but on the other hand – it takes a lot of effort and renewal and it makes me feel younger.&quot;<br /><br /><strong>Important part of autonomous systems</strong><br />Carl-Johan Seger is recruited as part of Chalmers activities in the Wallenberg project WASP – <a href="/en/areas-of-advance/ict/research/automated-society/wasp/Pages/default.aspx">Wallenberg Autonomous Systems and Software Program</a>. An important trend along with the development of autonomous systems is the decreasing gaps between hardware and software, we are seeing much more of programmable hardware. There are two very big benefits to doing so – increased performance and reduced energy consumption.<br /><br />&quot;When a large number of sensors are introduced to enable an autonomous system, and all sensors are sending their data to a central processor, it becomes inefficient and slow. Through programmable hardware, or FPGA, Field-Programmable Gate Array, we can introduce more intelligence closer to the sensors&quot;, says Carl-Johan Seger.<br /><br />FPGA are circuits in which the function of the circuit is determined by software. It provides flexibility, you do not necessarily need to re-design your hardware to introduce new functionality – just rolling out new instructions is enough. But there's a big challenge, it gets a lot more difficult to design and verify.<br />&quot;Look at cars for example, they contain many computer-powered features, and it's crucial that the systems respond quickly, never fail and are secured. This is what we are testing using formal methods&quot;, says Carl-Johan Seger. <br /><br />So, what does Carl-Johan Seger think about the future of self-driving vehicles out of a safety perspective? He says that there are several layers of technology in the vehicles – all are not critical systems.<br />&quot;There is a core in the systems that we need to find solutions for, in order for the self-driving vehicles to succeed. The future is about robust technology, but it's also about working out the regulations and what the consequences are if anything goes wrong. The market will determine how big risks that are reasonable to take. If the cost of errors becomes too large then we will not see any self-driving vehicles on the roads.&quot;<br /><br />Carl-Johan Seger points out that autonomous systems are not just about vehicles. We will see all sorts of new services, inspections, deliveries, window cleaning, and a host of applications in industry.<br />&quot;The development of autonomous systems leads to an increasing need to do right from the start – and thus it gets more and more important with verification. It is simply faster and less of a business risk to do it right the first time.&quot;<br /><br /><strong>Back at Chalmers</strong><br />Carl-Johan Seger is now recruited to Chalmers as Professor of Computer Science. Which means he is back at Chalmers where he started his studies in 1981, after nearly 34 years in Canada, the United States and Britain.<br />&quot;I don’t say I'm moving <em>back </em>to Sweden. I've been away for so long, so I say I'm moving to Sweden. It actually makes it a little easier for me.&quot;<br /><br />The first task at Chalmers is to build a verification system. Intel has proprietary ownership of the Forte system, so Carl-Johan Seger could not bring it to Chalmers for further research.<br />&quot;My wife usually says Forte is my fourth child, and maybe there is something to it. I have spent at least as many hours with Forte as with my three children.&quot;<br /><br />However, he has the old system to build on, the one he developed during his time as a researcher before leaving for Intel.<br />&quot;Now we are rebuilding, and this time, of course, it will go much faster because we already know the target.&quot;<br /><br /><br />Contact details: Carl-Johan Seger, <a href=""></a><br /><br /><em>Text: Malin Ulfvarson</em><br /><em>Photo: Anneli Andersson</em>Tue, 17 Oct 2017 09:00:00 +0200
