The initiative started in Canada to promote awareness on strain injuries of various types and celebrates 20 years 2020. Professor Anna-Lisa Osvalder at Chalmers University of Technology is an expert in ergonomics and gives her best tips on how to avoid RSI.</b></p><img src="/SiteCollectionImages/Institutioner/IMS/Design%20and%20Human%20Factors/200x249_AL-foto-CTH.png" class="chalmersPosition-FloatRight" alt="" style="margin-right:15px;margin-left:15px" /><span style="background-color:initial"><strong>Why do you get RSI?</strong></span><div>It could happen if you for some time have exerted certain muscles through low-strain tasks. Like using a computer and a computer mouse in your everyday work. You might experience a pain in the arm, neck, wrist and fingers. That pain is caused by an increased strain in the muscles and ligaments, tendons or nerves being overloaded. Also, stress can increase the risk of RSI because you often tighten your muscles.</div> <div>When working with a computer mouse, you hold your hand in an unnatural position, both holding the mouse and clicking it. The hand is bent back in an unnaturally large angle between the forearm and the hand and the muscles are constantly strained. In addition, the hand is usually slightly twisted, with a turn to the little finger. This causes a greater pressure on certain nerves and the muscles in the forearm are forced to work in an unnatural way.</div> <div><br /></div> <div><strong>What did you find in your study of so-called ergonomic computer mice?</strong></div> <div>First, I would like to point out that a so-called ergonomic computer mouse cannot have good ergonomics in itself. It is only in collaboration with the user we can study how well it can avoid incorrect use which may cause RSI.</div> <div>In our evaluation, we took a closer look at four ergonomic computer mice of different brands. We examined two aspects – usability problems and use errors – in interaction with the mice.</div> <div>In the study of the four mice, we found 75 possible ways to use the mice incorrectly! The user did not understand from the design of the mouse how it was supposed to be held or which finger to use to click. From this, we found that it was difficult for the user to guess how an ergonomic mouse should be used properly. And the wrong use causes a strain in the wrist, hand and fingers which in the long run can lead to RSI.</div> <div>The study shows the importance of informing and educating the users on how to handle an ergonomic mouse properly. We also found that it is important to develop mice that you intuitively understand how to use. The best design is the one where you can only use the product in one way – the correct way.</div> <div><br /></div> <div><strong>What are your best tips to avoid RSI?</strong></div> <div>There is no special treatment for RSI. Instead you need to find a way to prevent long-term strain. These simple tips can prevent RSI and reduce existing problems:</div> <div><ul><li>Take more breaks! Rather many short breaks than a few long ones.</li> <li>Change work posture frequently.</li> <li>Stretch your body and your wrists (see picture).</li> <li><span style="background-color:initial">Avoid using the computer mouse – learn how to use keyboard shortcuts instead.</span></li> <li>Change hands maneuvering the mouse. It is difficult at first, but practice and you will get in to it.</li> <li>Make sure the mouse and keyboard are at a proper distance from the body, the closer the better.</li> <li>Keep the wrist straight, slightly twisted towards the little finger when using the mouse, ie try to hold the wrist in a natural posture to reduce strain <em>(see picture above).</em></li> <li>Reduce work-related stress.</li></ul></div> <div><br /></div> <a href="/en/Staff/Pages/anna-lisa-osvalder.aspx"><div><strong>Anna-Lisa Osvalder </strong><span style="background-color:initial;color:rgb(51, 51, 51);font-weight:300">researches in ergonomics and biomechanics since 1986.

Congratulations to Maria Siiskonen, who was awarded a grant of SEK 50,000 from the Chalmers Foundation and Göran Wallberg&#39;s Memorial Fund in 2019, which will give funding for a four-month stay in Copenhagen, Denmark.</b></p><br /><div>
The Chalmers alum Göran Wallberg (VV-45) generously donated 2 million with the aim of helping students and younger researchers to gain international experience during their studies. The grant covers the areas of ICT (Information and Communication Technology), Production Technology and Environmental Technology.
</div> <div>&quot;It's a very nice Christmas present,&quot; says Maria Siiskonen, PhD student at the Department of Industrial and Materials Science, Chalmers. “I will use the grant for a research stay at the Technical University of Denmark, DTU, to learn more about adaptable manufacturing systems for personalized medicines.”</div> <div><br /></div> <div><strong>
Looking for solutions
</strong></div> <div>Maria Siiskonen's previous research has focused on product design and how different functionalities can be incorporated into medicines, for example in tablets. It makes it possible to adapt the medicine to the needs of the individual patient and thus optimize patients' treatments against a number of different diseases. 
</div> <div>A consequence from product customization is the accelerating number of product variants and previous studies indicate that current pharmaceutical production systems are not flexible enough to enable production of customized product in an economically feasible manner.
 </div> <div>“I want to take a closer look at how the production systems for individualized medicines to find how they should be designed, both from an economic and sustainable perspective.

A Novel Framework and Evaluation Methodology.&quot; on February 6, 2020. Opponent: Prof. Thomas J. Howard, Centre for Technology Entrepreneurship, Technical University of Denmark, Denmark Examiner: Prof. Rikard Söderberg IMS ​​</b></p><strong>Popular description</strong><div><div><div>Average consumer sees a car’s quality as a fancy mixture of a reliability, performance, design, aesthetics, and own previous experiences, unlike as a combination of mechanical parts, software pieces, advanced materials, cutting-edge manufacturing processes, with technical knowledge, skills and high production volumes – all ingredients involved into the modern car creation. Quite often, “humans do not see and act on the physical qualities of things, but on what they mean to them.” Closing the door of a Mercedes-Benz S-Class limousine produces signature sound with a vault-like thunk, making us react by generating multisensory images within ourselves. Handling certain premium quality wood panels gives a more sophisticated tactile impression than with a cheap plastic. The first olfaction, when entering a new Cadillac vehicle, creates a feeling of luxury, very different from that in a used car sold by a nearby car dealer shop.</div> <div><br /></div> <div>As one can see, understanding human’s perception of quality is a big challenge for researchers and practitioners. “What product features require the most attention for successful car design?” – The question engineers and designers need to answer under the pressure of shrinking product development time, a boost of available technologies, and financial limitations. Not to mention, the answer is expected to be given in numbers to sustain a fierce competition in the automotive industry. In that case, if a car manufacturing company wants to secure the ability to meet the consumer’s expectations, there is a need to control the perceived quality. Easy to say, hard to do.</div> <div><br /></div> <div>Perceived quality is a complex, multifaceted adaptive system - a system where a human is the main agent. Therefore, many perceived quality attributes are difficult to define explicitly. This fact creates a “wicked problem” for any car manufacturer. </div> <div><br /></div> <div>To confront the problem, we need to name it. For this reason, the perceived quality in engineering science has been defined and structured as the Perceived Quality Framework (PQF), in the form of a two-dimensional typology: (i) Technical Perceived Quality (TPQ), encompassing intrinsic attributes - everything that is part of a product and can be controlled by design and/or engineering specifications; (ii) Value-based Perceived Quality (VPQ), including extrinsic attributes - such as brand image, brand heritage, affective consumer judgments, design, hedonic or social values, the impact from other global attributes, advertising, and marketing promotion techniques. </div> <div><br /></div> <div>The perceived quality domain is a place where the product meaning, form, sensorial properties, and their execution intersect with human experience. Such an experience is driven by the interplay between product quality and its context. The ultimate goal is to find the trade-off between perceived quality elements. This resulted in the creation of the Perceived Quality Attributes Importance Ranking (PQAIR) method. The novel methodology was created to assist the engineer or designer in the decision-making process regarding the relative importance of perceived quality attributes for the final product. The PQAIR method illuminates the interplay between technical characteristics of the product and customer perceptions. The successful implementation of the method can help find an answer to the question, “What makes you, as a consumer, to fall in love with a specific car?” This is, after all, a very “expensive” question. Billion-dollar decisions in the automotive industry often rely on predictions and assumptions about how a customer will perceive and evaluate such a complex product as a car. The ontology of PQF and its principles shifts the perceived quality evaluation processes towards the objective and reproducible side. </div></div> <div><br /></div> <div></div> <div>Keywords: perceived quality, automotive, product development, product quality, premium, luxury,</div> <div>knowledge management, design, aesthetics, engineering;</div></div> <div><br /></div> <div><a href="https://research.chalmers.se/en/publication/514275"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the thesis</a></div> <div><a href="https://www.linkedin.com/in/kostas-stylidis/"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Kostas Stylidis on LinkedIn</a></div> <div><br /></div> <div><div><strong>Public defence</strong></div> <div>2020-02-06 09:00</div> <div>Virtual Development Laboratory (VDL), Chalmers Tvärgata 4C, Johanneberg Campus, Gothenburg</div></div> <div><br /></div> ​Wed, 15 Jan 2020 00:00:00 +0100https://www.chalmers.se/en/areas-of-advance/production/news/Pages/Chalmers-Sustainability-Day-2019---interview-.aspxhttps://www.chalmers.se/en/areas-of-advance/production/news/Pages/Chalmers-Sustainability-Day-2019---interview-.aspxChalmers Sustainability Day: Minimised waste and maximum use<p><b>The 8th of November, it&#39;s time for this year&#39;s edition of Chalmers Sustainability Day.

We want to give a broad perspective on the concept, ranging from business models, materials, product development to future civil society. The first talk of the day will be held by an invited speaker who can give a broad understanding and background to the theme.&quot;</div> <div><br /></div> <div><strong>Circular economy - how would you describe it?</strong></div> <div>&quot;Oh, there are many descriptions of it. To me it is about being able to dare to change from linear to circular business models. To achieve true sustainability, we not only need to change our technical conditions, but also the ways we consume. Everything has to be linked, from business value for those who produce and deliver products and services, to the actual customer benefit.&quot;</div> <div><br /></div> <div><strong>What do you hope Chalmers Sustainability Day will bring?</strong></div> <div>&quot;I want more people to be inspired and take circular economics into account in their research, in a wider sense than today.

Why the choice of circular economy as a theme?</b></div> <div></div> <div>- We chose to focus on circular economics, as it is a theme that unites many of Chalmers Areas of Advance. The solutions of the future lie in how we implement circularity in society and here we have an opportunity to discuss it thoroughly. The theme can work both for big issues and in the small perspective as an individual citizen. We believe the theme can inspire and provide new knowledge for everyone - students, researchers and other staff at Chalmers.</div> <div><br /></div> <div><strong> What does circular economy mean to you?</strong></div> <div>- It's a quite difficult concept and theme. There is not only one answer, but many. I would like to compare the concept of circular economy to an umbrella, under which several different contexts and definitions can be gathered.</div> <div><br /></div> <div><strong>What do you hope visitors will bring home from the event? </strong></div> <div>- I hope for increased commitment and an understanding of what circular economics is. I also wish for a broadened understanding that a sustainable future is a matter of creating solutions. I would also be interesting if the discussions include a questioning attitude regarding suggested solutions. A sharper dialogue and debate are important for showing a sustainable way forward.

They are expected to develop realistic yet visionary maintenance strategies to secure the success of highly digitalised production systems. However, this requires answers to many difficult questions. What type of technologies should be employed? What type of skills are needed? How should one collaborate with other parties? What are the benefits? Even with those answers in hand, the means by which the strategies can be realized are not well understood. How can we measure our current status and track our digitalisation progress over time? How should we prioritize our actions in order to reach our strategic targets? How can we learn from others? This thesis brings clarity to such questions. Specifically, this thesis describes future scenarios for maintenance in digitalised manufacturing, conceptualizes “Smart Maintenance”, and develops an instrument to measure Smart Maintenance in manufacturing plants.</div> <div>The scenarios allow practitioners to see the bigger picture of digitalisation, consider changes that they might otherwise ignore, and begin to develop long-term strategies for maintenance organizations. The rich, understandable, and action-inspiring conceptualization of Smart Maintenance brings clarity to practitioners and policy-makers, supporting them in developing implementation strategies and initiatives to elevate the use of Smart Maintenance. Specifically, Smart Maintenance is defined as “an organizational design for managing maintenance of manufacturing plants in environments with pervasive digital technologies” and has four core dimensions: data-driven decision-making, human capital resource, internal integration and external integration. The measurement instrument makes it possible to measure Smart Maintenance in manufacturing plants, and consists of a set of questionnaire items that measure the four dimensions of Smart Maintenance. It can be used by practitioners to assess, benchmark and longitudinally evaluate Smart Maintenance in their organization, which serves to develop evidence-based strategies for successful implementation.</div> <div>Taken together, this thesis provides a holistic understanding of Smart Maintenance that ensures high performance manufacturing in digitalised environments. To know more about what the future of maintenance entails, what Smart Maintenance really is, and how Smart Maintenance can be measured, you are kindly invited to turn this book around, open the first page, and start reading the thesis. I hope you will learn a lot.</div></div> <div><br /></div> <div><a href="https://research.chalmers.se/en/person/bokrantz"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />More about Jon Bokrantz</a></div> <div><br /></div>Tue, 24 Sep 2019 10:00:00 +0200https://www.chalmers.se/en/departments/ims/news/Pages/Vinh-win-in-European-master-thesis-competition.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Vinh-win-in-European-master-thesis-competition.aspxVinh-win in European master thesis competition<p><b>During the EUROMAT conference in Stockholm, a true Vinh-win situation happened.

Each system usually contains many individual components that have to work together properly so that the mechanical system as a whole functions. A modern aircraft engine, for example, contains about 18000 individual components. During manufacturing of most of the components, different metal cutting operations are used to cut the material (also called workpiece) into the desired shape. Obviously, the whole engine can only work safely and reliably if every single component has the exact right shape and dimension. Small deviations due to problems during the cutting processes can cause catastrophic failures during the service life of the aircraft engine. </div> <div>One problem that can arise during metal cutting operations is excessive wear of the tools that are used to cut the workpiece. In such a case, the component that is cut can be damaged and has to be scrapped since it cannot be applied for its purpose. This problem can be compared to cutting vegetables with a knife (your cutting tool) in your kitchen at home: After long cutting time and maybe depending on what types of vegetables you cut, the edge of your cutting tool can wear and get blunt. Instead of cutting precise slices of for example tomatoes, you will rather squish the tomato and get “damaged” slices with intolerable dimensions and properties. </div> <div>In order to avoid this problem during manufacturing of mechanical components, it is therefore important to know or predict when the cutting tool is too blunt to cut the workpiece precise enough. This is however difficult, because it is not well understood how the different constituents of the workpiece affect the wear of cutting tools. It is further complicated by the fact that workpieces can vary depending on their type and the producer. Similarly, the characteristics of a tomato (for example size and amount of hard seeds) can vary depending on what kind of tomatoes are used and where they were grown.</div> <div>This thesis aims at increasing the fundamental understanding of how the workpiece material and variations in its microstructure affect the wear of the tools used to cut it. This was achieved by controlled cutting tests during which the amount of tool wear was measured and compared when cutting different workpieces. Furthermore, the workpieces and worn cutting tools were studied at the microscopic scale to identify the mechanisms responsible for the wear. The gained knowledge can help to optimize the cutting process as it allows to predict how fast cutting tools wear down and when they have to be replaced. In that way the risk for having to scrap components can be reduced which is beneficial from an economical and an environmental standpoint and leads to more sustainable processing.</div> <div><br /></div></div> <div><a href="https://research.chalmers.se/en/publication/511696"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the thesis</a></div> <div><a href="https://research.chalmers.se/en/person/?cid=hoierp"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />More about Philipp Hoier</a></div> <div><br /></div>Tue, 10 Sep 2019 14:00:00 +0200https://www.chalmers.se/en/departments/ims/news/Pages/Modeling-and-experimental-characterization-of-large-biaxial-strains-and-induced-anisotropy-in-pearlitic-rail-steel.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Modeling-and-experimental-characterization-of-large-biaxial-strains-and-induced-anisotropy-in-pearlitic-rail-steel.aspxModeling and experimental characterization of large biaxial strains and induced anisotropy in pearlitic rail steel<p><b>​Knut Andreas Meyer, Doctoral Student at Material and Computational Mechanics​ IMS, defends his doctoral thesis on October 4th 2019.</b></p><div><b></b><span></span><div><b>Dissertation</b></div> <div>2019-10-04 09:00</div> <div>VDL, Chalmers Tvärgata 4C</div> <div>Opponent: Professor Odd Sture Hopperstad, NTNU, Norway</div></div> <strong><div><strong><br /></strong></div> Po​pular description</strong><div><div>Have you ever noticed how hard it is to bike with soft tires? What about how different it feels after you inflate them? The bike may roll more easily, but the bumps on the road are also more noticeable. The same happens for railway wheels: A steel wheel rolling over a steel rail has a very low rolling resistance. This makes trains very eco-friendly. The drawback, however, is a very high contact loading equivalent to the weight of 100 bikers on an area the size of a coin. This, together with forces from acceleration and braking, cause the surface layer of the rail to deform. As the deformations increase, the properties of the rail material change, and cracks appear. When the cracks become too large they need to be removed by maintenance grinding. This is a costly and slow operation that requires planning well in advance to avoid delayed trains. </div> <div> </div> <div>In this thesis, a new experimental method is presented. It is used to investigate how a material's properties are affected by large deformations. One important property is the yield limit. This is the maximum stress a material can withstand without permanently deforming. It is found that the yield limit is initially the same in all loading directions. After the deformations have accumulated, however, the yield limit depends on the loading direction. This effect is typically not accounted for when modeling the behavior of the rail material. Models that are capable of capturing this effect are therefore evaluated in this thesis. Such models can be used to optimize maintenance planning. Ultimately, our research should lead to smoother railway operations with fewer delayed trains.</div></div> <div><br /></div> <div><a href="https://research.chalmers.se/en/publication/512196"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read the thesis</a></div> <div><a href="https://research.chalmers.se/en/person/knutan"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />More about Knut Andreas Meyer​</a></div> <div><br /></div> ​Tue, 10 Sep 2019 14:00:00 +0200https://www.chalmers.se/en/departments/ims/news/Pages/Physically-based-constitutive-models-for-crash-of-composites.aspxhttps://www.chalmers.se/en/departments/ims/news/Pages/Physically-based-constitutive-models-for-crash-of-composites.aspxPhysically based constitutive models for crash of composites<p><b>​Sergio Costa, new doctor at Material and Computational Mechanics​, Industrial and Materials Science.</b></p>​<span style="background-color:initial">We congratulates Sergio Costa, new doctor at the Division of Material and Computational Mechanics, IMS. </span><div><span style="background-color:initial">On September 6th he successfully defended his doctoral thesis ”Physically based constitutive models for crash of composites”.

For this reason, the automotive industry investigates opportunities to reduce emissions, such as reducing the weight of the car. Composite materials, due to their high strength, stiffness and energy absorption to weight ratio, are a suitable material choice to reduce weight. The challenge here is that composites do not satisfy the fast development times and low costs required by the car industry. An efficient design phase, using more simulation and less physical testing, allows for time and cost-savings. However, there is a lack of efficient computational models to help the design with composite materials, which is fundamental for a widespread usage of composites in the automotive industry. This thesis presents the development, improvement and validation of constitutive models for composites in crash, focusing on compressive damage modes, matrix compression and fibre compression. The material being modelled is a carbon fibre/epoxy uni-weave Non-Crimp Fabric (NCF) composite. The properties of the composite constituents are homogenized to the ply level for a more efficient modelling.</div> <div><br /></div> <div>The matrix behaviour is modelled by combining damage and friction on the microcrack surfaces. The transverse mechanisms are modelled efficiently using a criterion for final failure, interaction of damage modes and a continuous response between compression and tension. The model is validated against 45- and 90-degree specimens. The fibre compression mode is fibre kinking growth, a very complex mechanism, responsible for high energy absorption. A homogenized 3D model based on Fibre Kinking Theory (FKT) is developed. It includes initial fibre misalignments and further rotations are governed by equilibrium with shear nonlinearity. The model is implemented in a commercial Finite Element (FE) software together with a mesh objective methodology. Furthermore, another formulation with similar physical principles but more suitable, efficient and robust for crash simulations is developed, implemented in an FE software and validated against experiments. The results show good qualitative and quantitative agreement. The proposed models allow for a reduction of physical testing required to develop crashworthy structures.</div></div> <div><br /></div> <div><a href="https://research.chalmers.se/en/person/?cid=sergioc"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read more</a></div> <div><br /></div></div></div>Tue, 10 Sep 2019 14:00:00 +0200https://www.chalmers.se/en/areas-of-advance/production/news/Pages/ICED-conference-to-Chalmers.aspxhttps://www.chalmers.se/en/areas-of-advance/production/news/Pages/ICED-conference-to-Chalmers.aspx​World-leading product development conference to Chalmers<p><b>​In August 2021, Chalmers University of Technology will host the world&#39;s largest scientific conference in product development, the 2021 International Conference of Engineering Design (ICED21).</b></p><div><span style="background-color:initial">The first ICED conference took place in Rome in 1983.

Their research could revolutionise the manufacturing of green products. Through emulating the natural cellular architecture of wood, they now present the ability to create green products derived from trees, with unique properties – everything from clothes, packaging, and furniture to healthcare and personal care products.</b></p>​<span style="background-color:initial">The way in which wood grows is controlled by its genetic code, which gives it unique properties in terms of porosity, toughness and torsional strength. But wood has limitations when it comes to processing. Unlike metals and plastics, it cannot be melted and easily reshaped, and instead must be sawn, planed or curved. Processes which do involve conversion, to make products such as paper, card and textiles, destroy the underlying ultrastructure, or architecture of the wood cells. But the new technology now presented allows wood to be, in effect, grown into exactly the shape desired for the final product, through the medium of 3D printing. </span><div><br /><div>By previously converting wood pulp into a nanocellulose gel, researchers at Chalmers had already succeeded in creating a type of ink that could be 3D printed. Now, they present a major progression – successfully interpreting and digitising wood’s genetic code, so that it can instruct a 3D printer.</div> <div><br /></div> <div>It means that now, the arrangement of the cellulose nanofibrils can be precisely controlled during the printing process, to actually replicate the desirable ultrastructure of wood. Being able to manage the orientation and shape means that they can capture those useful properties of natural wood.</div> <div><img src="/SiteCollectionImages/Institutioner/KB/Generell/Nyheter/Mimicking%20the%20ultrastructure%20of%20wood/Paul%20Gatenholm.png" class="chalmersPosition-FloatRight" alt="" style="margin:5px" /><br /><span style="background-color:initial">“This is a breakthrough in manufacturing technology. It allows us to move beyond the limits of nature, to create new sustainable, green products. It means that those products which today are already forest-based can now be 3D printed, in a much shorter time. And the metals and plastics currently used in 3D printing can be replaced with a renewable, sustainable alternative,” says Professor Paul Gatenholm, who has led this research within Chalmers University of Technology’s Wallenberg Wood Science Centre.</span><br /></div> <div><br /></div> <div>A further advance on previous research is the addition of hemicellulose, a natural component of plant cells, to the nanocellulose gel. The hemicellulose acts as a glue, giving the cellulose sufficient strength to be useful, in a similar manner to the natural process of lignification, through which cell walls are built.</div> <div><br /></div> <div>The new technology opens up a whole new area of possibilities. Wood-based products could now be designed and ‘grown’ to order – at a vastly reduced timescale compared with natural wood.</div> <div><br /></div> <div>Paul Gatenholm's group has already developed a prototype for an innovative packaging concept. They printed out honeycomb structures, with chambers in between the printed walls, and then managed to encapsulate solid particles inside those chambers. Cellulose has excellent oxygen barrier properties, meaning this could be a promising method for creating airtight packaging for foodstuffs or pharmaceuticals for example.</div> <div>“Manufacturing products in this way could lead to huge savings in terms of resources and harmful emissions,” he says. “Imagine, for example, if we could start printing packaging locally. It would mean an alternative to today's industries, with heavy reliance on plastics and C02-generating transport. Packaging could be designed and manufactured to order without any waste”.</div> <div><br /></div> <div>They have also developed prototypes for healthcare products and clothing. Another area where Paul Gatenholm sees huge potential for the technology is in space, believing that it offers the perfect first test bed to develop the technology further.</div> <div><br /></div> <div>“The source material of plants is fantastically renewable, so the raw materials can be produced on site during longer space travel, or on the moon or on Mars. If you are growing food, there will probably be access to both cellulose and hemicellulose,” says Paul Gatenholm.</div> <div><br /></div> <div>The researchers have already successfully demonstrated their technology at a workshop at the European Space Agency, ESA, and are also working with Florida Tech and NASA on another project, including tests of materials in microgravity.</div> <div><br /></div> <div>“Traveling in space has always acted as a catalyst for material development on earth,” he says.</div> <div> </div> <div>Read the article<a href="https://www.sciencedirect.com/science/article/pii/S2352940718304918?via%3Dihub#fig0025"> “Materials from trees assembled by 3D printing – Wood tissue beyond nature limits”​</a> published in Applied Materials Today.

of Advance Award for exploring the structure of proteins<p><b>​This year&#39;s Areas of Advance Award is given for the development of a unique method of analysing the structure and chemical composition of proteins. Increasing our knowledge of proteins could yield many advances, including the development of new and more effective drugs.</b></p>​The Areas of Advance Award this year goes to Martin Andersson, Pernilla Wittung Stafshede and Fredrik Höök, who combined materials analysis with biology using a clear multidisciplinary approach.<br /><br />“It is very encouraging to have our work highlighted in this way,” says Martin Andersson, who first initiated the research project.<br /><br />He contacted Pernilla Wittung Stafshede and Fredrik Höök to combine research expertise from the three departments of Chemistry and Chemical Engineering, Biology and Biological Engineering and Physics. The aim of the project is to develop a unique method for studying proteins, and thereby open up new knowledge and greater understanding of their functions.<br /><br /><strong>High resolution analysis</strong><br />An important group of proteins, especially when it comes to development of pharmaceuticals, are those found in the membrane of cells. About 60 percent of all pharmaceuticals target membrane-bound proteins, directly or indirectly, which shows their great importance. <br /><br />However, due to these proteins’ need for the cell membrane environment, it is difficult to analyse their structure with established methods, such as X-ray crystallography, magnetic resonance imaging or cryo-electron microscopy.<br /><br />The current project makes use of Atom Probe Tomography instead, with which both the structure and chemical composition of proteins can be observed. The technology offers enormous precision. At present the researchers have shown that it is possible to determine the structure of individual proteins with approximately 1 nanometre resolution. However, the challenge lies in designing a sample preparation method that makes the process faster, and allows to focus on individual proteins, which is the focus of the collaboration.<br /><br />“We still have a lot to learn about proteins, such as those that contribute to ‘misfolding’ diseases like Parkinson's and Alzheimer's. The proteins involved here are very flexible and begin to clump together during illness, but we do not know why and how because they are difficult to study with other methods,” says Pernilla Wittung Stafshede.<br /><br /><strong>New use of an established method</strong><br />Atom Probe Tomography is a well-established technology, but it has mainly been used previously to characterise metals and other hard materials. Applying the method to biological materials, especially proteins, shows an innovative approach. The researchers have continued work to develop and adapt the sample preparation process.<br /><br />“Our project can be described as high-risk – we do not yet know if it will be successful. But if we do succeed, it could potentially be of huge benefit. Getting the Areas of Advance Award is a strong encouragement to continue,” says Fredrik Höök, Professor of Physics.<br /><br />The current project has been financed by the Materials Science Area of Advance.<br />“It is very valuable that Chalmers' Areas of Advance can offer support for early testing of our idea. We need to be able to show preliminary results in order to successfully seek funds from external donors,” says Martin Andersson.<br /><br />Now, the first scientific article has been accepted, and the three researchers hope to expand the project going forward. A first application was made a couple of years ago but was rejected.<br /><br />“But now we have shown that the method works! Sometimes one has to ignore some of the accepted expertise and go on intuition. And then you have to have the opportunity to experiment,” says Martin Andersson.<br /><br /><div><br /> </div> <div><em>Text: Malin Ulfvarson</em></div> <div><em>Photo: Johan Bodell</em></div> <div><br /> </div> <strong>The Areas of Advance Award</strong><br />With the Areas of Advance Award, Chalmers looks to reward those who have made outstanding contributions to cross-border collaborations and who, in the spirit of the Areas of Advance, integrate research, education and utilisation. The award will be given out during the Chalmers doctoral conferment ceremony on 18 May, 2019. <br /><br /><strong>Recipients</strong><br />The project is led by Martin Andersson, Professor at the Department of Chemistry and Chemical Engineering, in collaboration with Professor Pernilla Wittung Stafshede, Biology and Biological Engineering and Professor Fredrik Höök, Physics.<br /><br /><strong>Note</strong><br />Chalmers were international pioneers in the development of Atom Probe Tomography for hard materials, a technology initiated by Professor Hans-Olof Andrén during the 70s. The application of Atom Probe Tomography to study proteins began a few years ago at the Department of Chemistry and Chemical Engineering, by a project group consisting of Dr. Gustav Sundell, Dr. Mats Hulander and doctoral student Astrid Pihl, under the leadership of Professor Martin Andersson.<br /><br /><br /><br /><strong>Previously published news articles about the three prize winners:</strong><br /><br />Martin Andersson: <a href="/en/departments/chem/news/Pages/Skeletal-imitation.aspx">Skeletal imitation reveals how bones grow atom-by-atom</a> (Nov 2018)<br /><br />Pernilla Wittung Stafshede: <a href="/en/departments/bio/news/Pages/Eating-fish-could-prevent-Parkinsons-disease.aspx">Eating fish could prevent Parkinson's disease</a> (May 2018)<br /><br />Fredrik Höök: <a href="/en/departments/physics/news/Pages/75-MSEK-for-developing-target-seeking-biological-pharmaceuticals.aspx">75 MSEK for developing target seeking biological pharmaceuticals</a> (Feb 2017) <br />Tue, 30 Apr 2019 11:00:00 +0200
