News: Mikroteknologi och nanovetenskap related to Chalmers University of TechnologyTue, 24 Mar 2020 15:33:45 +0100 Simpanen got her doctoral hat online<p><b>​Ewa Simpanen, PhD student at the Photonics Laboratory, was in the limelight when MC2 for the first time streamed a thesis defence online on 20 March. &quot;It was tricky to get a flow in the presentation with all the technical issues and the fact that I had two cameras in front of me in different directions,&quot; she says.</b></p><div><img src="/SiteCollectionImages/Institutioner/MC2/News/esimpanen_disp_350x305.jpg" alt="Picture of Ewa Simpanen." class="chalmersPosition-FloatRight" style="margin:5px" />Ewa Simpanen defended her thesis &quot;Longer Wavelength GaAs-Based VCSELs for Extended-Reach Optical Interconnects&quot; in front of a sparse audience in the lecture hall Kollektorn. In the simultaneous YouTube webcast, the audience was much bigger. The participants could also easily ask questions and make comments in the chat.</div> <div> </div> <div>The decision to broadcast the defence online was made at short notice as a result of the ongoing virus outbreak. The limited time for preparation led to some technical problems, which Ewa Simpanen describes as a &quot;roller coaster&quot;.</div> <div>&quot;At first everything worked as it should, but then the sound disappeared and we had to restart several times,&quot; she says.</div> <div> </div> <div>The grading committee and the opponent, Dr. Nicolae Chitica from Finisar Sweden AB, participated via link in the video conferencing system Zoom. He praised her for a solid and interesting job.</div> <div> </div> <div>Two unintended breaks made the public defense one of the longest in the department's history with its four hours. In retrospect, Ewa thinks back to the day with joy, despite the technical issues:</div> <div>&quot;I got a lot of support from everyone who watched my presentation remotely and I absolutely didn't feel alone! It was fun that colleagues in other parts of Europe who otherwise would not have been able to join me, could also follow me online. And what amazing cheers I received when it was announced that I had been approved! An absolutely incredible feeling! I am very happy and grateful to all those who watched and gave me their support, before, during and after the presentation.&quot;</div> <div><div><img src="/SiteCollectionImages/Institutioner/MC2/News/esimpanen_disp_665x330.jpg" alt="" style="margin:5px" /> </div> <h3 class="chalmersElement-H3">What is your thesis about? </h3></div> <div>&quot;I presented the work on my lasers, which are used for optical cables in mega data centers. These lasers make it possible to send data at high-speed over longer distances of fiber, up to a few km, while being both cost and power efficient,&quot; Ewa says.</div> <div> </div> <div>With her fresh PhD grade, she plans to venture out into the world:</div> <div>&quot;I want to continue working with photonics or semiconductors in the industry and am now looking for jobs at large companies in the US,&quot; she says.</div> <div><br /></div> <div>On the picture below, Ewa is nailing her thesis on the tree of knowledge in Canyon.<br /></div> <div> </div> <div><img src="/SiteCollectionImages/Institutioner/MC2/News/esimpanen_disp_350x305b.jpg" class="chalmersPosition-FloatLeft" alt="Picture of Ewa Simpanen." style="margin:5px" />Henric Fjellstedt, IT-responsible at the department, kept a watchful eye on the technology. Ewa Simpanen was very pleased with his efforts:</div> <div>&quot;Without Henric, this really wouldn't have worked! He fixed all the technical parts at really short notice. I'm also proud that we have a head of department who was with us all the way and helped everywhere he could, that's cool.&quot;</div> <div> </div> <div>Already, several upcoming thesis defences have been postponed, but MC2's head of department, Mikael Fogelström, opens up to stream more of them in the future - at least in times of crisis:</div> <div>&quot;I think that one must first and foremost protect the fact that a dissertation is one of the most important academic ceremonies we have. It is therefore of great value that as many as possible are present in the auditorium,&quot; he says.</div> <div> </div> <div>Text: Michael Nystås</div> <div>Photo: Dag Winkler, Michael Nystås and private</div> <div> </div> <div><a href="">Read Ewa Simpanen's doctoral thesis</a> &gt;&gt;&gt;</div>Tue, 24 Mar 2020 11:00:00 +0100 nanoplatelets prevent infections<p><b>​Graphite nanoplatelets integrated into plastic medical surfaces can prevent infections, killing 99.99 per cent of bacteria which try to attach – a cheap and viable potential solution to a problem which affects millions, costs huge amounts of time and money, and accelerates antibiotic resistance. 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 facing the big challenges<p><b>Research into everything from galaxies to human health, developing the shipping industry, electric vehicles, material properties and sustainable cities.

Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded multiple scientific articles, in publications including Nature Communications.</b></p>​<span style="background-color:initial">Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now. But to accommodate this digital lifestyle, a huge amount of data needs to be transmitted through fibre optic cables – and that amount is increasing at an almost unimaginable rate, consuming an enormous amount of electricity. This is completely unsustainable – at the current rate of increase, if no energy efficiency gains were made, within ten years the internet alone would consume more electricity than is currently generated worldwide. The electricity production cannot be increased at the same rate without massively increasing the usage of fossil fuels for electricity generation, which of course would lead to a significant increase in carbon dioxide emissions.</span><div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smarta%20datachips%20del%20av%20lösningen%20för%20att%20göra%20internet%20energisnålare/Peter-Andrekson_250x333px.jpg" class="chalmersPosition-FloatRight" alt="Peter Andrekson" style="margin:5px;width:200px;height:263px" /><br /><span style="background-color:initial">“The challenge lies in meeting that inevitable demand for capacity and performance, while keeping costs at a reasonable level and minimising the environmental impacts,” says Peter Andrekson, Professor of Photonics at the Department of Microtechnology and Nanoscience at Chalmers.</span><br /></div> <div><br /></div> <div>Peter Andrekson was the leader of the 5-year research project <a href="" target="_blank">‘Energy-efficient optical fibre communication’</a>, which has contributed significant advances to the field.</div> <div><br /></div> <div>In the early phase of the project, the Chalmers researchers identified the biggest energy drains in today's fibre optic systems.

An optical frequency comb emits light at all wavelengths simultaneously, making the transmitter very frequency-stable. This makes reception of the signals much easier – and thus more energy efficient.</div> <div><br /></div> <div>Energy savings can also be made through controlling fibre optic communications at the network level. By mathematically modelling the energy consumption in different network resources, data traffic can be controlled and directed so that the resources are utilised optimally. This is especially valuable if traffic varies over time, as is the case in most networks. For this, the researchers developed an optimisation algorithm which can reduce network energy consumption by up to 70%.</div> <div><br /></div> <div>The recipe for these successes has been the broad approach of the project, with scientists from three different research areas collaborating to find the most energy-saving overall solution possible, without sacrificing system performance.</div> <div><br /></div> <div><img src="/SiteCollectionImages/Institutioner/E2/Nyheter/Smarta%20datachips%20del%20av%20lösningen%20för%20att%20göra%20internet%20energisnålare/Erik-Agrell_250x333px.jpg" class="chalmersPosition-FloatRight" alt="Erik Agrell" style="margin:5px;width:200px;height:263px" />These research breakthroughs offer great potential for making the internet of the future considerably more energy-efficient.

In just minutes, their quantum computer performed a computational task that, according to the researchers, would have taken more than ten thousand years for a powerful supercomputer. Göran Johansson, one of the leaders of Chalmers quantum computer project, sees this as a major milestone.</b></p><div><span style="background-color:initial"><strong>How did you feel when you heard of the news?</strong></span><br /></div> <div>“I felt very happy! I knew that Google's research team was starting to get results with their 53-qubit quantum computer Sycamore, but that they have now managed to get such good reliability in their operations that they can perform this kind of calculation – it's a fantastic breakthrough!”</div> <div><br /></div> <div><strong>What lies behind the breakthrough?</strong></div> <div>“Sycamore is quite similar to Google's previous quantum computers in its structure. The breakthrough rather results from careful design of the hardware and software used to control the chip and a thorough analysis of which computational task to choose.”</div> <div><br /></div> <div><strong>Does this mean that quantum computers now outperform regular computers in general?</strong></div> <div>“No, absolutely not. The research team has shown that their quantum computer can solve a single calculation task better than a regular computer. The solved task is completely useless, it was chosen solely because it was judged to be easy to solve for a quantum computer but very difficult for a conventional one. But as quantum computers evolve, they will outperform conventional computers in more and more types of tasks.”</div> <div><br /></div> <div><strong>IBM criticizes Google’s calculations and states that their best supercomputer could solve the task in less than three days. What do you think about that?</strong></div> <div>“If that is the case, it would still be the first time a quantum computer performs something that requires the full capacity of the world's largest supercomputer, for almost three whole days, to reproduce. Whether it's ten thousand years or three days, I see the achievement of Google’s team as a very important step forward.”</div> <div><br /></div> <div><strong>What does this breakthrough mean to Chalmers quantum computer project?</strong></div> <div>“We are aiming for a quantum computer with one hundred well-functioning qubits, and Google has now shown that it is possible to create over fifty qubits that operate at over 99 percent reliability. It is incredibly inspiring and motivating!”</div> <div><br /></div> <div><strong>How does your quantum computer compare to Google’s?</strong></div> <div>“We use the same basic building blocks – superconducting circuits – as Google. So far, we are working, completely according to our plan, with a chip with only two qubits. Our strategy is to first get it to work really, really well on a small scale. For example, Google's qubits have an average lifetime of 16 microseconds, while we have over 80 microseconds. The longer the lifetime, the more computational operations you can do. On the other hand, Google has managed to reach significantly faster operations than we have, but we are working at getting really good at that as well. Then we will start to scale up in fairly large steps.”</div> <div><br /></div> <div><strong>What will be the next milestone in the development of quantum computers?</strong></div> <div>“Finding a useful problem that is beyond the reach of ordinary computers, but which a quantum computer with fifty to a hundred qubits can solve.
