Technologies are developing quickly, and the challenge of securing the to-be-connected systems leads industries to actively search for innovative solutions. </div> <div>&quot;Omen Technologies offers novel research-based methods for monitoring these types of systems in real time to detect implausible behaviour that may be due to either intentional malicious manipulation or unintentional failures. Our ambition is to commercialize our research-based technology to bring it to full potential, and thus contribute to the sustainability and safety of the imminent transition into a highly connected and digitalized society&quot; says Wissam Aoudi.</div> <div><br /></div> <div>Omen Technologies is part of <a href="">Chalmers Ventures Tech Transfer-program</a>.</div> <div><br /></div> <div><a href="">In this movie</a> Wissam Aoudi describes the technology and the research behind it. <h2 class="chalmersElement-H2">The ÅForsk scholarship</h2></div> <div>The scholarship is awarded so that the scholars with their solutions, services and products can create positive effects for social development. The scholars are selected through a nomination process where business developers from regionally based innovation environments across the country can suggest entrepreneurs. This year, a record number of applications were submitted.</div> <br /><div>Among the ten selected entrepreneurs, <strong>Johanna Nissén Karlsson</strong> and <strong>Simon Isaksson</strong> also represent Chalmers and Chalmers Ventures. </div> <div><br /></div> <div><a href="">Press release from SSIP</a> (in Swedish)</div> <div><br /></div> <div><h2 class="chalmersElement-H2">Contact</h2></div> <div><a href="/en/Staff/Pages/wissam-aoudi.aspx">Wissam Aoudi,</a> PhD student, Networks and Systems, Computer Science and Engineering</div> <div><br /></div> <div></div>Fri, 03 Apr 2020 00:00:00 +0200 culture gives Chalmers a good rating from the Swedish Higher Education Authority<p><b>​In five out of six areas, Chalmers University of Technology fulfils the requirements from the Swedish Higher Education Authority (UKÄ) for quality control of undergraduate and postgraduate education. In the area of gender equality, we are deemed to need to develop systems to systematically ensure equality aspects in the planning and shaping of our education in order to reach all the way. That is the indication from the review on quality control work for undergraduate and postgraduate education that UKÄ has recently completed.</b></p><div><img src="/SiteCollectionImages/20200101-20200701/AnnaKarlssonBengtsson_190909_03_250x350px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 10px" />“We can be very proud of the review we have received. UKÄ believes that the way our quality systems are integrated into Chalmers education is functional and benefits us and our students well, but it also shows that we need to have a better system in how we work with gender equality,” says Anna Karlsson-Bengtsson, who is the Vice President of Education and Lifelong Learning.</div> <div> </div> <div>UKÄ's assessment team finds that Chalmers has a well-developed and appropriate quality system, with a high level of ambition, which ensures the quality of the education. In particular, they highlight the fact that the quality control program is integrated with the university's other processes and structures, which gives a holistic view of strategic planning, prioritisation and follow-up.</div> <h2 class="chalmersElement-H2">Education according to the needs of the students</h2> <div>The organisation of undergraduate and Master's education, where the education programs order courses and the department teachers deliver these, also receives a positive assessment from the assessment group. This means that the courses are ordered from a student perspective with the students' needs in focus.</div> <div> </div> <div>The assessment group also emphasises that the introduction of the faculty model, which allows teachers to both teach and research, ensures close collaboration between education and research. The model means that both research-active teachers participate in the education and that the syllabuses and course content are updated based on the research that is ongoing at Chalmers.</div> <h2 class="chalmersElement-H2">The postgraduate education</h2> <div><img src="/SiteCollectionImages/20200101-20200701/AndersPalmqvist_180925_01_250x350px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px 10px" />The quality control work in the postgraduate education is characterised by the fact that each doctoral student has an individual study plan, which differs from the structure within the undergraduate education. Systematics in the quality work is achieved by prerequisites, degree objectives and rules of procedure for the doctoral students being designed and updated centrally within the postgraduate education board where the Doctoral Student Guild and the Head of Departments participate. Further quality control takes place within the network of graduate schools Presidents, where experiences of challenges and possibilities are exchanged. Good access to sufficient resources to employ doctoral students and the long-term work to support and develop supervisors in postgraduate education help to ensure high quality.</div> <div> </div> <div>“It is very positive that our quality work processes are considered to be of good quality. Chalmers has a very developed quality culture that is carried by our employees at all levels of the education and it is gratifying to now get it confirmed,” says Anders Palmqvist, who is Vice President of Research and Research Education.</div> <h2 class="chalmersElement-H2">Gender equality is a development area</h2> <div>When it comes to gender equality, the assessment team finds that Chalmers has routines and processes to ensure that the gender equality perspective is included when the educations are being conducted. However, a clearer way of working is needed to include gender equality in the continuous development of the content and shape of all educations.</div> <div> </div> <div>The architecture education is highlighted as a good example and the extensive investments in equality that Chalmers has started in recent years are an asset in the development work. Other good examples mentioned are, among other things, follow-up of equal treatment in the course evaluations, efforts to achieve a more equal gender balance among teachers and follow-up of inclusive working methods in group projects.</div> <h2 class="chalmersElement-H2">Participation, commitment and responsibility</h2> <div>All in all, the assessment group notes that Chalmers has systematic processes that encourage both teachers and other staff, as well as undergraduate and postgraduate students to participation, commitment and responsibility. There are clear and well-functioning routines that give both undergraduate and postgraduate students a good basis for influencing their education and a developed system for collaboration with the industry and the surrounding world. Chalmers also ensures that the educations prepare students to meet changes in the working life.</div> <div> </div> <div>“The quality work in undergraduate and postgraduate education is always ongoing. Now we have received a confirmation that our way of working is really good – and that is a good starting point, among other things for our work with equality,” says Anna Karlsson-Bengtsson.</div> <div><br /></div> <div><strong>Read more:</strong></div> <div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Quality assurance of higher education and research</a></div> <div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />The full report on the results for Chalmers University of Technology</a> <em>(Only in Swedish)</em><br /></div> <div><br /></div> <div><br /></div> <div><strong>Text:</strong> Anita Fors</div> <div><strong>Photo:</strong> Johan Bodell/ Chalmers<br /></div> <div> </div>Thu, 02 Apr 2020 15:00:00 +0200 and engineering on Instagram<p><b>​April 3rd is the theme day, IGEday – Introduce a Girl to Engineering Day. Under normal circumstances, companies and other organisations open their doors to showcase opportunities within the technology sector. Due to the outbreak of the coronavirus, digital channels will now serve as meeting places and information sources instead. The student initiative Chalmers Women&#39;s Association will go live on Chalmers’ Instagram account on Friday, with an hour full of inspiration and information about the engineering profession, focusing on the target group of young girls and non-binary people.</b></p>Chalmers wants to get more young people interested in technical education, and to increase their understanding of the kind of career opportunities that exist with a degree in engineering. It is clear that Chalmers should take part in the IGEday initiative, but this year, due to the ongoing outbreak of the Coronavirus, it is not possible to invite students to campus-based activities. The plan was to let approximately seventy students aged 13–19 visit Chalmers during the day and for the Chalmers Women's Association to host an inaugural speech. Now they will aim to inspire young people through the Chalmers Instagram account instead!<div><br /></div> <div><div><strong><img src="/SiteCollectionImages/20200101-20200701/CWA%20och%20IGEday/HannaS_textbild_cwa.jpg" alt="Hanna Svensson" class="chalmersPosition-FloatLeft" style="margin:5px;width:150px;height:156px" />Hello there, Hanna Svensson, founder and chairwoman of Chalmers Women's Association. What is IGEday?</strong></div> <div>The theme day IGEday in Sweden was originally an initiative from female engineers and engineering students through the Womengineer Foundation. They want to increase interest in technology among young girls and non-binary people, aged 13-19. Companies, organisations and universities around Sweden participate in the day to show some examples of what working as an engineer can be like.</div> <div><br /></div> <div><strong>What is the Chalmers Women's Association (CWA)?</strong></div> <div>The Chalmers Women's Association (CWA), is a non-profit association for female and non-binary Chalmers students and alumni. We started partly because we wanted to create a network for female students at Chalmers and partly because we want to push the work on equality forward. We want to show that it is obvious that everyone, regardless of gender, should have the same opportunities both during and after their studies. Unfortunately, this is not always the case. There are many prejudices that hold women back in the tech industry and we want to change that!</div> <div><br /></div> <div><strong>Why do you get involved in IGEday?</strong></div> <div>More women and non-binary people are needed in the field of tech! Through our participation in IGEday at Chalmers, we hope that we can inspire young girls and non-binary people and broaden the view of what it means to be an engineer and what opportunities and careers the technical sector can offer!</div> <div><br /></div> <div><strong>Why do you think girls are underrepresented at many technical educational programmes today?</strong></div> <div>I believe that many young people today, faced with choosing an education and profession, look to a large extent at the existing gender balance, and that they are formed by the traditions, prejudices and expectations that exists in society. If you are not sure what you want to do in the future, I think you are looking for role models and people you can relate to. Since there are not so many women in the tech industry, it can be difficult to find role models, and instead you choose the programme where you think you might find other like-minded women, instead of focusing on what you are really interested in yourself.</div> <div><br /></div> <div><strong>Why is it important to introduce more women to the tech world and to engineering professions?</strong></div> <div>It is important that everyone gets the same opportunity and conditions in their choice of education! By trying to introduce more women to the tech world, more people can find role models and inspiration for upcoming educational and professional choices.</div> <div><br /></div> <div>In addition, I think that increased equality in the technology industry is a matter of democracy! The digitisation and electrification of society affects everyone, and to be able to create safe and well-suited technologies for all people, diversity in the groups and companies developing them is required!</div> <div><br /></div> <div><strong>Why did you apply to Chalmers and the engineering profession yourself?</strong></div> <div>I always wanted to study engineering because I am a creative person, I have always liked math and I want to work together with other people! I applied to Chalmers because I liked the close collaboration that exists with the world of industry and research. It inspires and motivates me a lot in my studies, and it is cool to be able to see and to contribute to solutions to real problems during your studies.</div> <div><br /></div> <div>I’m a third-year student on the mechanical engineering programme and am very happy about that. I chose mechanical engineering because I thought it offered a good combination of basic engineering skills, such as math and physics, but also a deeper understanding of organisation and production.</div> <div><br /></div> <div><strong>What do you want to do in your future career?</strong></div> <div>I want to work in the industry and develop tomorrow's digital solutions to increase efficiency, quality, sustainability and create new business models. In addition, there are so many cool technologies like AI, VR, digital twins and autonomous robots and this is something I would love to learn more about. There are a lot of fun and exciting things going on in the tech industry right now and digitalisation will fundamentally change the industry. Being part of that shift is very exciting!</div> <div><br /></div> <div><strong>Tell us more about your live broadcast on Instagram!</strong></div> <div>We will go live on the account<a href="">​</a> at 13.00 on Friday 3 April. There will be opportunities to ask questions. We will give tips on how to become an efficient problem solver, and there will also be a problem-solving competition during the day. We hope to inspire others, to help broaden the view of what an engineer does and to smash some prejudices about girls in tech!</div></div> <div><br /></div> <div><div><br /></div> <div><a href="" target="_blank" title="Chalmers instagram"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Chalmers instagram account</a></div> <div><a href="" target="_blank" title="Chalmers Women Association"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Chalmers Women's Association</a></div> <div><a href="" title="IGE-day och Womengineer" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />IGE-day och Womengineer​</a> (In Swedish)</div></div> <div><br /></div> <div><br /></div> <div><strong>Text:</strong> Julia Jansson</div> <div><strong>Photo:</strong> <span style="background-color:initial">Chalmers Women's Association</span></div> <div><br /></div>Thu, 02 Apr 2020 00:00:00 +0200’s-most-innovative-entrepreneurs.aspx is one of Sweden’s most innovative entrepreneurs<p><b>Simon Isaksson, researcher at Department of Physics at Chalmers, has received ÅForsk’s annual scholarship for entrepreneurs. ​</b></p><div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Simon%20Isaksson_webb.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px;width:280px;height:280px" /><div><span style="background-color:initial">He is one of ten Swedish entrepreneurs selected, and the innovation is named Aquammodate. </span><span style="background-color:initial">The concept is based on a water purification filter with high selectivity and 100 times lower energy consumption.

But the technology will also enable less waste of resources and induce a development towards a more sustainable society.​</b></p>​<span style="background-color:initial">What differs 5G from the previous generations of mobile standards is that the communication largely is controlled by software, and that the ‘cloud’ is moved closer to the users and applications.</span><div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/5G%20möjliggör%20kommunicerande%20prylar%20och%20hållbarhet/Tommy_Svensson_2016_150x200px.jpg" class="chalmersPosition-FloatRight" alt="Tommy Svensson" style="margin:5px;width:170px;height:228px" />“5G is an enabler for digitalisation and more efficient processes”, says Tommy Svensson, Professor of communication systems, focusing his research on wireless communications. “This means that machines can exchange information with each other, and that many devices are connected at the same time. Sensors are collecting large amounts of data of various kinds, which are processed rapidly for tailor-made and intelligent applications.”</div> <div><br /></div> <div>“Sometimes, I call myself a digital navvy; I'm building wireless digital roads. My research deals with the infrastructure and how data traffic can travel wirelessly, quickly and without obstacles. At the Department of Electrical Engineering at Chalmers University of Technology we are successful in our research on mobile systems, in my area with the focus on radio traffic to and from base stations in the mobile network, as well as in research on mobile base stations and vehicle communications.”</div> <div><br /></div> <div><strong>Fast, robust and powerful</strong></div> <div>5G consists of more advanced technical solutions than 4G and therefore enables the technology to be used for many more purposes. The researchers regard 5G as a tool for solving major societal challenges: climate impact, scarce natural resources, food production, care for an aging population, safe working environments, etc.</div> <div><br /></div> <div>“This new technology not only enables ‘Internet of information’ but also ‘Internet of skills’. That means that the exchange of information, as well as skills and abilities, can be performed from a distance,” Tommy Svensson continues. “For example, the possibility of remotely controlling machines in a mine from a safe and comfortable office above ground. Or surgery that can be performed from a distance and thus enabling more patients to benefit from the expertise of specialist doctors.”</div> <div><br /></div> <div>In order to perform this kind of advanced tasks correctly and safely from a distance, the communication system must be robust and allow very quick data transports. 5G may reduce delays in the data transmission to as short as 1 millisecond. The network can then also be virtually divided into software-controlled slices, where different slices can be designed and dynamically created for individual tasks. In that way the performance is ensured.</div> <div><br /></div> <div>Augmented reality is a concept that is often mentioned in the context of 5G. It means combining reality with digital content, via a mobile phone or through special glasses, that allows for the surroundings to be experienced with computer generated images placed on top. The faster the data transfer is, the more applications are available.</div> <div><br /></div> <div><strong>Paves the way for greater sustainability</strong></div> <div>“In my opinion, 5G clearly enables a transfer from a ‘wear and tear’ mentality to a society that is based on a higher degree of sustainability”, says Tommy Svensson. “Partly it is about the technology itself, and partly about what can be achieved by using the technology.”</div> <div><br /></div> <div>The 5G technology saves energy by streamlining the control of radio signals and by transferring only what is really needed – no superfluous system information needs to be handled. This makes the connection ten times more energy efficient than 4G of today.</div> <div><br /></div> <div>Through various applications of 5G, processes can be made more efficient and consume less resources. This means that it will be possible to benefit from individual and condition-based solutions, provided by multi-connected machines that are able to exchange information with each other.</div> <div><br /></div> <div><strong>Many applications</strong></div> <div>“In smart cities, public transports and other means of transportation can be adapted to external circumstances and to people's intentions”, Tommy Svensson exemplifies. “This makes the traffic flow smoother and less energy-consuming in total. The same applies to water consumption, waste management and other community services. Self-driving cars may not have their breakthrough as fast as originally anticipated, but by using mobile technology it is evident that they eventually will be an important component of the smart transport system of the future.”</div> <div><br /></div> <div>In agriculture, it will be possible to individually regulate watering and fertilization according to the needs of each plant through connected farm machinery and systems for data analysis. Another example is industrial production systems that can be made more flexible and thus enabling faster adjustments of the production to new conditions. If the machine park is equipped with connected sensors, maintenance measures can be adapted to the actual need without causing unplanned downtime.</div> <div><br /></div> <div>“In the future, the driving force for manufacturing companies will be more focused on creating offers that are sustainable, since it will be the services provided rather than the products themselves that the customers want to pay for,” says Tommy Svensson. “This development is being promoted in the connected 5G community.”</div> <div><br /></div> <div>E-health; using digital tools and exchanging information digitally to achieve and maintain good health, is an area also of great interest related to the 5G technology. The possibilities range from virtual meetings with doctors from home to sensors on the body and in textiles that record and analyze health data, thus providing individual-based diagnostics and treatment.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/5G%20möjliggör%20kommunicerande%20prylar%20och%20hållbarhet/smartcity_710x467px.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><br /><br /><br /><br /></div> <div><br /><br /><br /></div> <div><strong><br /></strong></div> <div><strong><br /></strong></div> <div><strong><br /></strong></div> <div><span style="background-color:initial"><em>In the connected 5G community, sensors in our everyday environment will collect real-time data and send radio signals via fixed and mobile base stations to masts in the mobile network, and also in the opposite direction.

However, the opportunities outweigh the risks. I am confident that we will find a good balance.”</div> <div><br /></div> <div><strong>New generations will follow</strong></div> <div>On a small scale, 5G networks already exist. The development of the technology is in full swing and in autumn 2020, <a href="" target="_blank">the Swedish Post and Telecom Authority ​</a>will hold an auction of the frequency ranges for 5G. The introduction will take place in stages, where several mobile network generations will exist in parallel. The industry's assessment is that the major breakthrough of the 5G technology will be in five to ten years.</div> <div><br /></div> <div>To most people, 5G might be a new and exciting technology, but the aim of the researchers is now set for 6G.</div> <div><br /></div> <div>”Currently, we have some interesting research projects underway. For example, we want to study how to integrate artificial intelligence into the sixth generation of mobile communication networks”, says Tommy Svensson. “When AI becomes part of the communication system, you can really talk about a revolution in intelligent services. 6G is likely to be introduced around year 2030.”</div> <div><br /></div> <div>Text: Yvonne Jonsson</div> <div><br /></div> <div><div><strong>For more information, contact</strong></div> <div><a href="/en/staff/Pages/tommy-svensson.aspx">Tommy Svensson</a>, Professor in the Communication systems research group, where he is leading the wireless systems research, Department of Electrical Engineering, Chalmers University of Technology</div> <div><a href=""></a></div></div> <div><br /></div> <div><br /></div> <div><h2 class="chalmersElement-H2">Facts about 5G</h2> <div><br /></div> <div><ul><li>Machine to machine communication – a large increase in the number of connected gadgets that are able to exchange information with each other, also called ‘Internet of Things’.</li> <li>Considerable growth in data traffic – about 1000 times more than today. 5G can handle a larger amount of data from multiple devices simultaneously.</li> <li>Higher transmission speed – top speeds up to 10 times higher than 4G, about 10 Gbit / second.</li> <li>Less latency, shorter response times – about 1 millisecond compared to 25-35 milliseconds today.</li> <li>Lower energy consumption – the connection via 5G becomes ten times more energy efficient than today's 4G. 5G requires only 0.2 watts of energy to transmit 1 megabyte of data.</li> <li>Hig​<span style="background-color:initial">her frequencies – in its first stage, 5G uses the frequency band 3.4-3.8 GHz, and in the future also the millimeter wave band (over 24 GHz).

Several authorities and organisations have already sounded the alarm about the dangerous lack of competence in this area. Now, the EU programme Euratom is investing around 5 million euros in educating a new generation of researchers and specialists in nuclear technology. Researchers from Chalmers University of Technology are at the heart of the initiative - based on online education.​​​​</b></p><div><div>The programme covers two major educational projects, of which Chalmers will coordinate one and participate as a partner in the other. Both aim to maintain competence in, respectively, reactor physics and nuclear chemistry.</div> <div><br /></div> <img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/ChristopheDemazière_20190614_beskuren_200x250.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><div>“If we do not maintain a sufficient level of knowledge and expertise, this could be a safety and security risk. There are more than a hundred nuclear reactors currently operating across Europe, which account for more than 25 percent of all electricity generation,” says Christophe Demazière, Professor at the Department of Physics at Chalmers and coordinator of the EU project Great Pioneer.</div> <div><br /></div> <div>As nuclear power plants are decommissioned, so interest in nuclear technology education has diminished throughout Europe. This has led several authorities and organisations, including the European Commission and the International Atomic Energy Agency (IAEA), to sound the alarm that a new generation of qualified researchers and specialists is needed to ensure nuclear safety. The Swedish Radiation Safety Authority (SSM) and the Swedish National Council for Nuclear Waste have voiced similar concerns.</div> <div><br /></div> <div>A report from SSM makes clear the nuclear industry’s great need for more experts in the next fifteen years. There is also a growing need for radiation science specialists, within areas such as healthcare. Within the Swedish nuclear industry and healthcare, a growing proportion of the expert workforce is expected to retire within a few years.</div> <div><br /></div> <div>The same trend is evident throughout Europe. As early as 2012 the Joint Research Center (JRC) warned the European Commission that there would be a shortage of around 7000 reactor physics and nuclear safety specialists by 2020. Since the report was written, several training programmes in the area have disappeared, which has contributed to increasing the shortfall further still.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Modelling%20algorithms_webb.jpg" class="chalmersPosition-FloatRight" alt="" style="background-color:initial" />The teaching of the three-year EU project Great Pioneer is based on innovative and successful methods in active and distance learning. Coordinator Christophe Demazière has developed these methods for many years, in close collaboration with two pedagogical researchers at Chalmers University of Technology’s Department of Communication and Learning in Science: Associate Professors Christian Stöhr and Professor Tom Adawi.

The model can be used to predict metabolic behaviour in cells, which can help researchers identify novel metabolic markers or drug targets for many diseases, such as cancer, type 2 diabetes, and Alzheimer’s disease.</b></p><p class="chalmersElement-P">​<span>“Human1 will transform the way in which scientists develop and apply models to study human health and disease”, says project leader Jens Nielsen, Professor in Systems and Synthetic Biology, at the Department of Biology and Biological Engineering at Chalmers University of Technology, about the model that was recently published in in Science Signaling.</span></p> <p class="chalmersElement-P">Metabolism is the network of chemical reactions providing cells with the building blocks and energy necessary to sustain life. Studying the individual components of human metabolism and how they function as part of a connected system is therefore critical to improving health and treating disease. To study such a complex system, computational tools such as genome-scale metabolic models have been developed. </p> <p></p> <h2 class="chalmersElement-H2">Human1 − ​highest quality genome-scale model</h2> <p></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Human1 is the newest, most advanced, and highest quality genome-scale model for human metabolism.

The integration revealed metabolic differences of clinical relevance, such as potential drug targets for cancers of the liver and blood. Furthermore, Human1 was demonstrated to predict the effect of gene disruptions with substantially greater accuracy than previous human models.</p> <p class="chalmersElement-P"> </p> <p></p> <h2 class="chalmersElement-H2">&quot;An advancement in the area of human metabolic modelling​&quot;</h2> <p></p> <p class="chalmersElement-P">A major limitation for human metabolic models has been the difficulty in simulating realistic reaction rates due to the infeasibility of obtaining the necessary measurements. However, the authors demonstrated that applying an enzyme-limitation framework to Human1 enabled the prediction of realistic growth and metabolite exchange rates without requiring these difficult measurements. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“This is a considerable advancement in the area of human metabolic modelling,” says Jens Nielsen. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“The framework now unlocks many powerful approaches that have typically only been feasible for studying microbes and it will enable a wide use of the model for studying metabolic diseases.”</p> <p></p> <h2 class="chalmersElement-H2">​Metabolic Atlas provides maps for metabolic pathways</h2> <p></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">In parallel with Human1, the researchers developed Metabolic Atlas, an online resource to explore and visualise the model.

This is according to research from Chalmers University of Technology, Sweden, in the journal Small.​</b></p><p class="chalmersElement-P">​<span>Every year, over four million people in Europe are affected by infections contracted during health-care procedures, according to the European Centre for Disease Prevention and Control (ECDC). Many of these are bacterial infections which develop around medical devices and implants within the body, such as catheters, hip and knee prostheses or dental implants. In worst cases implants need to be removed.</span></p> <p class="chalmersElement-P">Bacterial infections like this can cause great suffering for patients, and cost healthcare services huge amounts of time and money. Additionally, large amounts of antibiotics are currently used to treat and prevent such infections, costing more money, and accelerating the development of antibiotic resistance.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“The purpose of our research is to develop antibacterial surfaces which can reduce the number of infections and subsequent need for antibiotics, and to which bacteria cannot develop resistance. We have now shown that tailored surfaces formed of a mixture of polyethylene and graphite nanoplatelets can kill 99.99 per cent of bacteria which try to attach to the surface,” says Santosh Pandit, postdoctoral researcher in the research group of Professor Ivan Mijakovic at the Division of Systems Biology, Department of Biology and Biotechnology, Chalmers University of Technology. </p> <p class="chalmersElement-P"> </p> <p></p> <h2 class="chalmersElement-H2">​&quot;Outstanding antibacterial effects&quot;</h2> <p></p> <p class="chalmersElement-P">Infections on implants are caused by bacteria that travel around in the body in fluids such as blood, in search of a surface to attach to. When they land on a suitable surface, they start to multiply and form a biofilm – a bacterial coating.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">Previous studies from the Chalmers researchers showed how vertical flakes of graphene, placed on the surface of an implant, could form a protective coating, making it impossible for bacteria to attach – like spikes on buildings designed to prevent birds from nesting. The graphene flakes damage the cell membrane, killing the bacteria. But producing these graphene flakes is expensive, and currently not feasible for large-scale production.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“But now, we have achieved the same outstanding antibacterial effects, but using relatively inexpensive graphite nanoplatelets, mixed with a very versatile polymer. The polymer, or plastic, is not inherently compatible with the graphite nanoplatelets, but with standard plastic manufacturing techniques, we succeeded in tailoring the microstructure of the material, with rather high filler loadings , to achieve the desired effect. And now it has great potential for a number of biomedical applications,” says Roland Kádár, Associate Professor at the Department of Industrial and Materials Science at Chalmers.</p> <p class="chalmersElement-P"> </p> <p></p> <h2 class="chalmersElement-H2">​No damage to human cells</h2> <p></p> <p class="chalmersElement-P">The nanoplatelets on the surface of the implants prevent bacterial infection but, crucially, without damaging healthy human cells. Human cells are around 25 times larger than bacteria, so while the graphite nanoplatelets slice apart and kill bacteria, they barely scratch a human cell. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“In addition to reducing patients’ suffering and the need for antibiotics, implants like these could lead to less requirement for subsequent work, since they could remain in the body for much longer than those used today,” says Santosh Pandit. “Our research could also contribute to reducing the enormous costs that such infections cause health care services worldwide .”</p> <p></p> <h2 class="chalmersElement-H2">​Correct orientation is the decisive factor</h2> <p></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">In the study, the researchers experimented with different concentrations of graphite nanoplatelets and the plastic material. A composition of around 15-20 per cent graphite nanoplatelets had the greatest antibacterial effect – providing that the morphology is highly structured.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">“As in the previous study, the decisive factor is orienting and distributing the graphite nanoplatelets correctly. They have to be very precisely ordered to achieve maximum effect,” says Roland Kádár.</p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The study was a collaboration between the Division of Systems and Synthetic Biology at the Department of Biology and Biological Engineering, and the Division of Engineering Materials at the Department of Industrial and Materials Science at Chalmers, and the medical company Wellspect Healthcare, who manufacture catheters, among other things. The antibacterial surfaces were developed by Karolina Gaska when she was a postdoctoral researcher in the group of Associate Professor Roland Kádár. </p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P">The researchers’ future efforts will now be focused on unleashing the full potential of the antibacterial surfaces for specific biomedical applications.</p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><strong>Read the scientific article in the scientific journal Small</strong></p> <p class="chalmersElement-P"><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /></a><span style="background-color:initial"><font color="#333333"><a href="">Precontrolled Alignment of Graphite Nanoplatelets in Polymeric Composites Prevents Bacterial Attachment​</a></font></span></p> <p class="chalmersElement-P"> </p> <p class="chalmersElement-P"><strong>Read the previous news text, from April 2018</strong></p> <p class="chalmersElement-P"><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" /></a><span style="background-color:initial"><a href="/en/departments/bio/news/Pages/Spikes-of-graphene-can-kill-bacteria-on-implants.aspx">Spikes of graphene can kill bacteria on implants​</a></span></p> <p class="chalmersElement-P"><br /></p> <p class="chalmersElement-P"><strong>Text:</strong> Susanne Nilsson Lindh and Joshua Worth<br /><strong>Ilustration:</strong> Yen Strandqvist</p> <p class="chalmersElement-P"> </p>Mon, 23 Mar 2020 00:00:00 +0100 Sustainability week, back this autumn<p><b>​The sustainability week, Act Sustainable, will be back this autumn November 16-20.

However, lots of the water resources such as rivers, lakes and groundwater are continuously contaminated by discharges of chemicals from industries and urban area. It’s an expensive and demanding process to remove all the increasingly present contaminants, pesticides, pharmaceuticals, perfluorinated compounds, heavy metals and pathogens. Graphil is a project that aims to create a market prototype for a new and improved way to purify water, using graphene.</b></p><div>Graphene enhanced filters for water purification (GRAPHIL) is one of eleven selected spearhead projects funded by The Graphene Flagship, Europe’s biggest initiative on graphene research, involving more than 140 universities and industries located in 21 countries. Chalmers is the coordinator of the Graphene Flagship. </div> <div><br /></div> <div> </div> <div>The purpose of the spearhead projects which will start in April 2020, building on previous scientific work, is to take graphene-enabled prototypes to commercial applications. Planned to end in 2023, the project aims to produce a compact filter that can be connected directly onto a household sink or used as a portable water purifying device, to ensure all households have access to safe drinking water.</div> <div><br /></div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Material%20och%20tillverkning/VincenzoPalermo.png" alt="Vincenzo Palermo" class="chalmersPosition-FloatLeft" style="margin:10px;width:196px;height:216px" /><br />&quot;This is a brand-new research line for Chalmers in the Graphene flagship, and it will be a strategic one. The purification of water is a key societal challenge for both rich and poor countries and will become more and more important in the next future. In Graphil, hopefully we will use our knowledge of graphene chemistry to produce a new generation of water purification system via interface engineering of graphene-polysulfone nanocomposites,&quot; says Vincenzo Palermo, professor at the Department of industrial and materials science. </div> <div> </div> <h2 class="chalmersElement-H2">Graphene enhanced filters outperforms other water purification techniques</h2> <div>Most of the water purification processes today are based on several different techniques. These are adsorption on granular activated carbon that removes organic contaminants, membrane filtration that removes for example, bacteria or large pollutants, and reverse osmosis. Reverse osmosis is the only technique today that can remove organic or inorganic emerging concern contaminants with high efficiency. Reverse osmosis has however high electrical and chemical costs both from the operation and the maintenance of the system. </div> <div> </div> <div>Many existing contaminants present in Europe’s water sources, including pharmaceuticals, personal care products, pesticides and surfactants, are also resistant to conventional purification technologies. Consequently, the number of cases of contamination of ground and even drinking water is rapidly increasing throughout the world, and it is matter of great environmental concern due to their potential effect on the human health and ecosystem.</div> <div> </div> <div>Graphil is instead proposing to use graphene related material polymer composites. Thanks to the unique properties of graphene, the composite material favours the absorption of organic molecules. Its properties also allow the material to bind ions and metals, thus reducing the number of inorganic contaminants in water. Furthermore, unlike typical reverse osmosis, granular activated carbon and microfiltration train systems, the graphene system will provide a much simpler set up for users. </div> <div><br /></div> <div><span><img src="/SiteCollectionImages/Institutioner/IMS/Material%20och%20tillverkning/Grafenprov.jpg" alt="Grafenprov" style="margin:5px;width:660px;height:309px" /><span style="display:inline-block"></span></span><br /></div> <div><br /></div> <div>Graphil will not just replace all the old techniques, but significantly out-perform them both in efficiency and cost. The filter works as a simple microfiltration membrane, and this simplicity requires lower operation pressures, amounting in reduced water loss and lower maintenance costs for end users.</div> <div> </div> <h2 class="chalmersElement-H2">Upscaling the technique for industrial use</h2> <div>Chalmers has, in collaboration with other partners of the Graphene Flagship, investigated during the last years the fundamental structure-property relationships of graphene related material and polysulfones composition in water purification. A filter has then been successfully developed and validated in an industrial environment by the National Research Council of Italy (CNR) and the water filtration supplier Medica.</div> <div><br /></div> <div>Now the task is to integrate the results and prove that the production can be upscaled in a complete system for commercial use.</div> <div><br /></div> <div>Prof. Vincenzo Palermo and Dr. Zhenyuan Xia from the department of Industrial and Materials Science, Chalmers will support Graphil with advanced facilities for chemical, structural and mechanical characterization and processing of graphene oriented-polymer composite on the Kg scale. Chalmers’ role in the project will be to perform chemical functionalization of the graphene oxide and of the polymer fibers used in the filters, to enhance their compatibility and their performance in capturing organic contaminants.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/IMS/Material%20och%20tillverkning/ZhenyuanXia_grafenprov_600px.jpg" alt="Zhenyuan Xia" class="chalmersPosition-FloatRight" style="margin:15px 10px;width:295px;height:207px" /><br />&quot;We are very excited to begin this new activity in collaboration with partners from United Kingdom, France and Italy, and I hope that my previous ten years’ international working experience in Italy and Sweden will help us to better fulfil this project,&quot; says Zhenyuan Xia, researcher at the Department of industrial and materials science. </div> <div> </div> <div> </div> <h2 class="chalmersElement-H2">Partners</h2> <div>Graphil is a multidisciplinary project that consists of both academic and industry partners. The academic partners include Chalmers, the National Research Council of Italy (CNR) and the University of Manchester. The industrial partners are Icon Lifesaver, Medica SpA and Polymem S.A – all European industry leaders in the water purification sector. The aim is to have a working filter prototype that can be commercialized by the industry for household water treatment and portable water purification.  </div> <div> </div> <h2 class="chalmersElement-H2">Funding</h2> <div>The Graphene Flagship is one of the largest research projects funded by the European Commission. With a budget of €1 billion over 10 years, it represents a new form of joint, coordinated research, forming Europe's biggest ever research initiative. The Flagship is tasked with bringing together academic and industrial researchers to take graphene from academic laboratories into European society, thus generating economic growth, new jobs and new opportunities.</div> <div> </div> <div>The total budget of the spearhead project GRAPHIL will be 4.88 million EURO and it will start from April 2020 with a total period of 3 years.</div>Sun, 22 Mar 2020 00:00:00 +0100 elected member of the Royal Swedish Academy of Sciences<p><b>​Fredrik Höök, Professor of Physics at Chalmers University of Technology, is a new member of the Royal Swedish Academy of Sciences.

The project focuses on encapsulating biological pharmaceuticals into nanoscale carriers in order to reach the body’s cells and treat severe diseases.</div> <div><br /></div> <div>In his research, Fredrik Höök is studying the role of the cell membrane in cellular communication, which play a key role in many biological processes and diseases. The membrane is essential for the cell’s ability to communicate with its surroundings and is the entry site for viruses. Sometimes particles of membrane can also detach to form “communication capsules”, (microvesicles), which transport molecular information to other cells. </div> <div><br /></div> <div>Fredrik Höök and his research group have developed new methods for microscoping combined with handling small quantities of liquid. One of their main aims is to analyze the microvesicles – exosomes – used by cells to communicate with each other. </div> <div><br /></div> <div>To make maximum use of the sensitive measuring methods, the researchers have designed structures that behave in the same way as cell membranes. This enables them to biophysically study how cell membranes interact with nanoparticles of various kinds, such as viruses and exosomes.</div> <div><br /></div> <div>Fredrik Höök’s research group uses artificial cell membranes to carry out in-depth studies of individual nanoparticles that have been attached to the membrane. The researchers also develop a bioanalytical tool capable of measuring the size, structure, and optical properties of individual particles. This will enable the research team to make detailed analyses of complex biological samples, and they also hope to be able to sort nanoparticles according to their properties.</div> <div><br /></div> <div>The aim is to better understand how the nanoparticles work, and what enables them to penetrate the cell. Höök wants to use that knowledge to design artificial exosomes as drug delivery vehicles.</div> <div><br /></div> <div>“Hopefully, this could lead to improved disease diagnostics and inspire new ways of developing and administering medication. Findings from the research may also answer fundamental questions about the properties of nanoparticles and how they interact with cell membranes. This may also be of benefit in the field of nanosafety, and in many other areas,” says Fredrik Höök. </div> <div><br /></div> <div><a href="/en/staff/Pages/Fredrik-Höök.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Read more about Fredrik Höök and his research.​</a><br /></div> <div><a href="/en/research/our-scientists/Pages/The-Royal-Swedish-Academy-of-Sciences.aspx" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" /> More Chalmers researchers in the Royal Swedish Academy of Sciences​</a><br /></div> <div><br /></div> <div><div><strong>Text</strong>: Mia Halleröd Palmgren, <a href=""></a></div> <div><strong>Image:</strong> Johan Bodell​<span style="background-color:initial">​</span></div></div> <div><span style="background-color:initial"><br /></span></div> <div><div><h2 class="chalmersElement-H2"><span>Press releases and articles about </span><a href="/en/Staff/Pages/Fredrik-Höök.aspx">Fredrik Höök </a><span>and his research</span></h2></div> <div><div><a href="/en/departments/physics/news/Pages/Prestigious-Wallenberg-grant-to-Physics-Professor---.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Physics Professor chosen to be Wallenberg Scholars​​</a><br /></div> <div><a href="/en/departments/physics/news/Pages/Investigating-cell-stress-for-better-health-–-and-better-beer.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Investigating cell stress for better health – and better beer</a></div> <div><a href="/en/departments/physics/news/Pages/75-MSEK-for-developing-target-seeking-biological-pharmaceuticals.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />75 MSEK for developing target seeking biological pharmaceuticals</a></div> <div><a href="/en/departments/physics/news/Pages/A-Chalmers-innovation-paves-the-way-for-the-next-generation-of-pharmaceuticals.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Chalmers paves the way for the future of designed pharmaceuticals</a></div> <div><a href="/en/centres/gpc/news/Pages/Portrait-Fredrik-Hook.aspx"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/ichtm.gif" alt="" />Portrait: A matter of life and Science​</a></div></div></div> <h2 class="chalmersElement-H2">All the new members of the Royal Swedish Academy of Sciences:</h2> <div>At the General Meeting on 11 March Fredrik Höök, Chalmers University of Technology, and Martin Malmsten, University of Copenhagen were elected Swedish members of the Academy’s class for technical sciences, Taija Mäkinen and Staffan Svärd, Uppsala University and Martin Högbom, Stockholm University were elected members of the class for biological sciences and Barbara Canlon, Karolinska Institutet, was elected foreign member of the Academy’s class for medical sciences.</div> <div><div><br /></div> <div><a href=""><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more about the new members of the Academy</a></div></div> <div></div>Fri, 20 Mar 2020 00:00:00 +0100 reality – the future of safe Arctic shipping<p><b>​Maritime traffic in the Arctic region is rapidly increasing which in turn has led to an increased risk of maritime casualties in the region. Now researchers at Chalmers together with the Oslo School of Architecture and Design have developed an AR tool in a VR-environment that will be able to help officers on the bridge to make the right decision under pressure whilst navigating the risky Arctic waters.</b></p>Maritime traffic in the northern Arctic Ocean is now increasing as more shipping-lanes are ice-free for longer periods of time due to the increased melting of sea ice as a result of climate change. However, navigating in Arctic waters is dangerous because of icebergs, rapid weather changes and, in some cases, lack of experience in the ships’ crew. This can lead to accidents and the release of oil and hazardous chemicals for example.<p></p> <p>“As an officer, you need a lot of experience to navigate the shipping routes in the Arctic Ocean. For example, a highly trained eye is required to determine if it is newly formed ice that the ship can easily pass through or if it is hard multi-year ice that can tear the hull”, says Monica Lundh, associate professor and Head of Unit at Maritime Human Factors at the Department of Mechanics and Maritime Sciences.<br /></p> <h2 class="chalmersElement-H2">Safe Arctic Bridge</h2> <p>The research project SEDNA aims to improve the safety of maritime operations in the Arctic. One part of this project is to define the “Safe Arctic Bridge” which has been a collaborative effort between the Oslo School of Architecture and Design and Chalmers. Augmented reality (AR) solutions have been developed based on ship visits, feedback from subject matter experts and simulator exercises that help officers on board avoid hazards such as icebergs, shallow waters and other vessels. In the future, the AR solutions will be based on big data from, for example, satellite, radar, sensors and charts. Katie Aylward, PhD student at the unit for Maritime Human Factors:</p> <p><img src="/SiteCollectionImages/Institutioner/M2/Nyheter/vr-ar320x320.jpg" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /></p> <p><span style="background-color:initial">“The Arctic environment adds increased pressure on the crew. A unique work environment, paired with information from a variety of sources, presented on different interfaces can be very stressful. This can lead to an inaccurate assessment of a situation, leading to poor decision-making. Our hope is that the AR solutions will give officers the most relevant information for the situation, at the right time to help them make the right decision under pressure in a harsh environment.”</span></p> <h2 class="chalmersElement-H2">Testing in a VR/AR-lab</h2> <p>In order to test the AR solutions safely, they have been developed and implemented in a Virtual Reality (VR) bridge environment. The Maritime Human Factors researchers have created a “VR/AR lab” to test the solutions on both future mariners – students in their last year at the Maritime program at Chalmers, and more experienced mariners – simulator instructors and industry personnel. </p> <p>&quot;To get feedback from mariners with different experiences and with different perspectives is valuable for the continued development and eventual real-world implementation of the AR-tool. We don’t know when it will happen, but the advantage of AR solutions is that they can be applied to existing vessels and are not dependent on redevelopment on the bridge. However, to ensure safe Arctic navigation, I hope it is sooner rather than later,&quot; says Katie Aylward.</p> <p><br /></p> <p><strong style="background-color:initial">Facts:</strong><span style="background-color:initial"> AR is an abbreviation for Augmented reality where digital elements are added to reality in real-time.

Given Chalmers’ size as a workplace and study environment, it is important we help reduce the spread of the coronavirus in this way. Of course, it will require great efforts by all staff and students, but the difficult situation society is in requires extraordinary measures and we must all contribute in the ways we can,” says Chalmers President Stefan Bengtsson.</div> <div> </div> <div>Chalmers had already, in common with many other educational institutions, imposed certain restrictions on visits, business and study trips, and conferences, for example. These are now further tightened – no international business trips, and within Sweden only operationally critical trips permitted.

This is currently valid until 31 May.</div> <h2 class="chalmersElement-H2">Remote exams</h2> <div>During the exam week now in progress, all exams are being conducted remotely. Some of the many reasons behind this decision are that examinations mean many people will gather in a small area, in many cases pensioners, who may be at increased risk of complications from an infection.</div> <div>The students will now take the exams at home and submit through Canvas, the digital learning platform used in many educational tasks, and which is already widely used in teaching at Chalmers under normal conditions.</div> <div> </div> <div>“So far, it has worked very well, thanks to great efforts by programme directors to transform the original examinations to digital formats, so they can be taken from home.
