But a major challenge facing this transition is that the gas is explosive when mixed with air. For this reason, it is crucial to be able to detect hydrogen leaks as early as possible. Now researchers at Chalmers University of Technology, Vrije Universiteit Amsterdam and Eindhoven University of Technology, have developed an optical sensor that can detect record low levels of hydrogen.</b></p><div>Hydrogen is seen as an important part of the decarbonisation of the heavy transport sector and around the world hydrogen-powered trains, trucks and airplanes are being developed and deployed. Even in heavy industry, hydrogen is regarded as very important, for example for the production of fossil-free steel. </div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">The risks of storing or using hydrogen are well known. Only four percent hydrogen is required in air for the formation of an explosive mixture (knallgas) that can ignite at the slightest spark. Therefore, it is important that ultra-sensitive sensors are in place to monitor leaks and alarm at critical levels.</span></div> <div><span style="background-color:initial"><br /></span></div> <div style="font-size:16px"><span style="background-color:initial">Safety of utmost importance in hydrogen use</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">Together with Dutch colleagues, researchers at the Department of Physics at Chalmers University of Technology, Sweden, have now developed an optical hydrogen sensor that detects record-low levels of hydrogen. It thus joins the most sensitive sensors in the world.  <a href="https://doi.org/10.1038/s41467-022-33466-8" target="_blank">The new research results are presented in an article in Nature Communications</a>.</span></div> <div><br /></div> <div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/400_ChristophLanghammerfarg.jpg" class="chalmersPosition-FloatRight" alt="Christoph Langhammer" style="margin:5px;width:180px;height:236px" />&quot;Safety is of the utmost importance in all use and storage of hydrogen. If leaks are detected early, they can be fixed so that you hopefully do not have to take the plant or vehicle out of service at all,&quot; says Chalmers Professor</span><strong style="background-color:initial"> Christoph Langhammer</strong><span style="background-color:initial">, one of the main authors of the scientific article.</span></div> <div><span style="background-color:initial"><br /></span></div> <div style="font-size:16px"><span style="background-color:initial">AI technology led the way</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">The optical hydrogen sensor consists of many metal nanoparticles that work together to detect hydrogen in their surroundings. The approach to how the new sensor was designed differs from what has been done previously. Instead of producing a large number of samples and testing them individually to see which one works best, the researchers have used advanced AI technology to create the optimal interaction between the particles based on their distance to each other, diameter and thickness. The result is a sensor that detects changes in hydrogen concentration that are as small as a few hundred thousandths of a percent.</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">The secret behind the new sensor's low detection limit is the combination of the arrangement of the particles in a regular pattern on a surface and their fine-tuned dimensions. This turned out to be more favourable for the sensitivity of the sensor than the random particle arrangement used in previous sensors of the same type.</span></div> <div>Christoph Langhammer's research group has previously been able to present <a href="/en/departments/physics/news/Pages/Worlds-fastest-hydrogen-sensor-could-pave-the-way-for-clean-hydrogen-energy.aspx">the world's fastest hydrogen sensor​</a>. For him, it is clear that many different types of sensors are needed and that they have to be optimised for specific applications.</div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial">&quot;The technology around hydrogen has taken a giant leap and therefore today's sensors need to be more accurate and tailored for different purposes. Sometimes a very fast sensor is needed, sometimes one is needed that works in a harsh chemical environment or at low temperatures. A single sensor design cannot meet all needs”, says Christoph Langhammer, who is also one of the founders of a new competence centre: TechForH2.</span></div> <div><span style="background-color:initial"><br /></span></div> <div style="font-size:16px"><span style="background-color:initial">Industry and academia in new collaboration on hydrogen</span></div> <div><span style="background-color:initial"><br /></span></div> <div><span style="background-color:initial"><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Tomas%20Grönstedt_400.jpg" class="chalmersPosition-FloatRight" alt="Tomas Grönstedt" style="margin:5px;width:180px;height:270px" />The new Chalmers-led centre brings together both academia and industry to develop new hydrogen technology with focus on the decarbonisation of heavy transport systems.

Now, for the first time, a signal has been measured that is believed to be precisely this phenomenon. Thomas Nilsson, Professor at the Department of Physics at Chalmers University of Technology, has participated in the experiment and tells us more about the discovery. </b></p>​<span style="background-color:initial">Our world is made up of atoms, whose nuclei consist of protons and neutrons. Whether a system made up entirely of neutrons can exist has long eluded the world of physics, and more than half a century has passed since searching for it began. Twenty years ago, scientists found signs of the tetraneutron after an experiment in which neutron-rich beryllium isotopes collided with carbon atoms, but the result had large margins of error and was difficult to interpret.</span><div><br /></div> <div>During a large-scale experiment carried out by a big international research team at the Radioactive Ion Beam Factory at RIKEN in Japan, it has now been possible for the first time to demonstrate what is believed to be an observation of the tetraneutron; four neutrons that are fleetingly connected. The experiment was carried out in 2016, but it has taken until now to analyse the complex measurements, <a href="https://doi.org/10.1038/s41586-022-04827-6">the results of which have been presented in Nature</a>.</div> <div><br /></div> <div style="font-size:16px">Better understanding of the atomic nucleus</div> <div><br /></div> <div><strong><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Thomas%20Nilsson_400x415.jpg" class="chalmersPosition-FloatRight" alt="Thomas Nilsson" style="margin:5px 10px;width:180px;height:189px" />Thomas Nilsson</strong>, Professor of experimental subatomic physics and Head of the Department of <span style="background-color:initial">Physics at Chalmers, is part of the research team. In short, the driving force behind this type of research is the curiosity to better understand the world, he says.</span></div> <div><br /></div> <div>“The tetraneutron can help us understand the microcosm and how the atomic nucleus is built right down to the quark level – the smallest demonstrated building blocks of matter. It would be an extreme system to study and could give us insights into the strong interaction between neutrons and protons in an atomic nucleus, one of the four interaction types found in nature and the most complicated one to study, says Thomas Nilsson.</div> <div><br /></div> <div>“The tetraneutron can also give us insights into the processes that take place in the universe's neutron stars. Large parts of them are made up of neutrons alone, and it is believed that heavy elements are created when neutron stars collide.”</div> <div><br /></div> <div style="font-size:16px">A neutron star in the lab</div> <div><br /></div> <div>Experimental studies of neutron systems are challenging because free neutrons decay within minutes. Therefore, the researchers cannot start from them. To create a system where the neutrons could interact only with each other during the experiment, the researchers used nuclear reactions with atomic nuclei that already have a large excess of neutrons. The researchers overcame the challenge by creating a beam of the isotope helium-8 (with two protons and six neutrons) and firing it at half the speed of light at a target of hydrogen. Thus, a collision was created where sometimes only four neutrons remained. In turn, they formed into a system of four – albeit as fleetingly as for 10<sup>-</sup><sup>22</sup> seconds (0.0000000000000000000001 seconds).</div> <div><br /></div> <div>By measuring the mass and energy of the particles before and after the collision, the tetraneutron could be detected by the energy that was missing in the measurement after the collision.</div> <div><br /></div> <div>“In the past there have been indications of the tetraneutron, but they have not been statistically significant. Now we have received a very clear signal and you can say that we have possibly created a minimal neutron star in the lab”, says Thomas Nilsson.</div> <div><br /></div> <div>Further studies will be required to confirm the result of the experiment. In a few years, the German accelerator facility FAIR, Facility for Antiproton and Ion Research, is expected to be completed. There, the researchers will, among other things, be able to produce matter that is usually only found in space.</div> <div><br /></div> <div>“At FAIR, you will be able to measure all four neutrons separately. Then we will really be able to say whether it is a four-neutron system that we have found”, says Thomas Nilsson.</div> <div><br /></div> <div style="font-size:15px"><strong>More about the scientific article and the research:</strong></div> <div><ul><li>The article <a href="https://doi.org/10.1038/s41586-022-04827-6">“Observation of a correlated free four-neutron system“</a>, M.

The platform provides teachers and students with a common educational environment and access to the same information, so that students have equal learning opportunities regardless of geographical location and individual level of knowledge. They have now been awarded the Bert-Inge Hogsved Award for Best Entrepreneurship by the Forum for Engineering Physicists at Chalmers.  </b></p><div><span style="background-color:initial"><strong>Simon Pettersson Fors</strong> and <strong>Eric Lindgren</strong> are the recipients of this year’s <a href="https://tekniskafysiker.wordpress.com/bert-inge-hogsveds-pris/">Bert-Inge Hogsved Award for Best Entrepreneurship</a>. The award was established in 2011 by <strong>Bert-Inge Hogsved</strong>, himself an engineering physicist. The award is presented annually to students studying the programmes Engineering Physics, Engineering Mathematics or Chemical Physics with Engineering Physics. The intention is to highlight entrepreneurial initiative among students at Chalmers. </span></div> <div><br /></div> <div><span style="background-color:initial"></span>A study conducted by the Swedish Board of Student Finance (CSN) in 2020 revealed that diminished mental wellbeing is significantly more common among students than skilled workers. Studies were perceived as overly demanding and stressful. </div> <div><br /></div> <div>“As a student, one is often frustrated, unable to make progress, something that creates stress. On our learning platform, it is easy to get help. Anyone can ask a question and it can be answered by both other students and teachers. All students remain anonymous in order to remove the stigma attached to ignorance,” Simon Pettersson Fors, doctoral student at the Department of Microtechnology and Nanoscience.</div> <div><br /></div> <div>The learning platform, Yata, is an open forum that facilitates joint discussion to solve various problems. As all questions and answers are available to everyone, the platform can help many students simultaneously. All information is saved for posterity, making the learning platform a knowledge bank for future students and a tool for streamlining teaching.</div> <div><br /></div> <div>For teachers, the primary benefit is saved time. A teacher can speak to the entire group at once, rather than emailing individual students. It also provides them with an opportunity to check that students are on the right track in their reasoning and plan the next stage of teaching based on ongoing discussions in the forum. They can also use earlier pedagogical posts by former teachers and students. </div> <div><br /></div> <div>“There are many learning platforms on the market but few aimed at learning physics, engineering and mathematics at higher education level. It’s great to be involved in solving problems that one has personal experience of as a student,” says Eric Lindgren, doctoral student at the Department of Physics. </div> <div><br /></div> <div style="font-size:16px">For more information, please contact:</div> <div><a href="/en/Staff/Pages/forssi.aspx">Simon Pettersson Fors</a></div> <div><a href="/en/Staff/Pages/Eric-Lindgren.aspx">Eric Lindgren</a></div> <div><br /></div> <div><strong>Text and photo:</strong> <a href="https://www.hogia.se/">Hogia</a></div> ​Tue, 29 Mar 2022 13:00:00 +0200https://www.chalmers.se/en/departments/physics/news/Pages/Thesis-with-a-personal-touch-receives-this-years-Best-Thesis-Award.aspxhttps://www.chalmers.se/en/departments/physics/news/Pages/Thesis-with-a-personal-touch-receives-this-years-Best-Thesis-Award.aspxThesis with a personal touch awarded at Physics<p><b>​​Magnus Rahm is the winner of the Department of Physics' annual prize for best doctoral thesis. A thesis that is not only distinguished by its playful cover and strong scientific impact – but also by its personal appeal and pedagogical features.</b></p>​​<span style="background-color:initial">The Department of Physics' Best Thesis Award for the academic year 2020/2021 goes to Dr. <span style="font-weight:700">Magnus Rahm</span>, for his dissertation entitled &quot;There is an Alloy at the End of the Rainbow: Structure and Optical Properties From Bulk to Nano&quot;.</span><span></span><div><br /></div> <div style="font-size:15px">The award committee's motivation for the award is:</div> <div><em>&quot;This year's award for the best PhD thesis goes to Magnus Rahm. The committee selected his thesis for its strong scientific impact as well as its pedagogical qualities. The thesis reflects Dr. Rahm's ability to solve complex problems requiring not only a profound and comprehensive understanding of physics and materials science, but also advanced technical skills in data analysis and software development. The thesis is easy to read and succeeds to introduce a complex subject to readers not familiar with the field. The committee also appreciated the author's personal touch throughout the thesis and in the cover art.”</em></div> <div><br /></div> <div><span style="font-weight:700">How does it feel to receive this award?</span></div> <div>”I’m of course very happy. You put a lot of time and energy into your thesis so the fact that someone has read and appreciated it is of course delightful. I was a little surprised, there were many good theses this year,and it almost feels a bit unfortunate that not everyone can get an award. But I was very happy with my own thesis.”</div> <div><br /></div> <div><span style="font-weight:700">What do you examine in your thesis?</span></div> <div>“I have done simulations of materials, it is about material physics so they always start on the atomic or electron scale. I have looked at several different materials, but the common denominator is that there is some connection to nanoparticles and alloys, ie a mixture of metals. There is also a connection to hydrogen, as my project is partly funded by a larger project run by Professor Christoph Langhammer, which deals with hydrogen sensors made of nanoparticles.”</div> <div><br /></div> <div><span style="font-weight:700">Why did this topic attract you?</span></div> <div>”Doing physics through computer simulations appealed to me very much. Partly because I am clumsy in the lab, partly because this is the perfect way to do experiments as you have a precise view of what is happening. I also like data analysis and programming, so it was probably the combination of things I was drawn to.”</div> <div><br /></div> <div><span style="font-weight:700">Your thesis is called &quot;There is an alloy at the end of the rainbow&quot;. What is it at that you find at the end of the rainbow, more precisely?</span></div> <div>“It’s those fantastic materials that you can only imagine before you have them. Through simulations you can search for materials in a simpler way than through physical experiments. You can test more variants and you do not have the same limitations, it does not cost time or money to change an element, so you are free to search the entire periodic table. In terms of results, it is difficult to point to one single thing because the thesis consists of several different articles with quite different orientations, but what I think will perhaps have the biggest impact in the long run is the software we developed in the group during the time of my thesis.”</div> <div><br /></div> <div><span style="font-weight:700">In their motivation, the award committee writes that your thesis is easy to read and succeeds in introducing the reader to a complex subject. How was your writing process?</span></div> <div>”It is a fairly scattered thesis - my challenge was to turn it into a whole. The thing that tied it all together at the end was the explanation for why I chose the subject from the beginning. I spent a lot of time writing an introduction that would tie everything together. I also think it's fun to write and to articulate, and I had a lot of help from discussions with my supervisor Professor <strong>Paul Erhart</strong>.”</div> <div><br /></div> <div><span style="font-weight:700">What did you find difficult during the writing process?</span></div> <div>”In addition to getting the whole thing together, I could sometimes have a writer’s block and difficulty getting started, but the most important thing then was to just start writing about what felt motivating for the moment, instead of thinking that I had to write it from the beginning to the end.”</div> <div><br /></div> <div><span style="font-weight:700">Your dissertation also has a very special cover. Tell us more about it!</span></div> <div>“In the world of physics for the past 10–20 years, it has been popular with photorealistic 3D renderings of nanoparticles, small atoms, and so on. I have made these types of illustrations myself and wanted to do something else. I googled around and stuck to an illustration with video game aesthetics that I was inspired by. That way I could get all the different parts and details in the same picture. In addition, the cover indicates that the thesis is about something digital, simulations with ones and zeros. I put way too many hours on the cover!”</div> <div><br /></div> <div><span style="font-weight:700">What are you doing now?</span></div> <div>”I'm still in Paul Erhart's group, now as a postdoc. So I now do research on other materials, but in the same place.”</div> <div><br /></div> <div><span style="font-weight:700">Last but not least, do you have any good advice for those about to write a thesis themselves?</span></div> <div>”That you should not be afraid to be personal. In everything else you write within academia, several names appear as the sender and you write for scientific journals with strict guidelines. In a thesis, it is not quite the same. The product of five years of doctoral studies is not only the articles, but also yourself – you have become a doctor. I think that the thesis to some extent can reflect who you are, so if you think that sounds like a good idea, you should not be afraid to be a little bold. I tried to put my personal stamp on the thesis by having a twinkle in the eye where it suited, especially in the introductory chapter, but also in the introduction of each chapter. Everything does not have to be bone dry!”</div> <div><br /></div> <div><a href="https://research.chalmers.se/en/publication/?id=523675" target="_blank"><img class="ms-asset-icon ms-rtePosition-4" src="/_layouts/images/icgen.gif" alt="" />Read Magnus Rahm's thesis via research.chalmers.se</a></div> <div style="font-size:15px"><br /></div> <div style="font-size:15px">About the Best Thesis Award</div> <div>The Best Thesis Award was founded in 2013, as one among several initiatives at the Department of Physics, to maintain and improve the research quality, as well as to show appreciation for the PhD students' hard work.</div> <div>The management of the department also hopes that this award can help doctoral students receive an extra boost in their careers after the defence.

The purpose of the award is to draw attention to outstanding contributions for students in applied physics and applied mathematics at Chalmers.</b></p><strong>​</strong><span style="background-color:initial"><strong>What does it mean for you to receive this prize?</strong></span><div>“I am very happy and honoured. It is great to know that the students appreciated my lectures. As a former Engineering Physics student (enrolled 1991) I feel a strong connection with the students. I got lots of positive energy from them during the whole course. And that they even nominated me for this fantastic prize, it is unbelievable!”</div> <div><br /></div> <div><strong>How did you set up the course to make the students feel committed, and what do you think of as success factors in your teaching?</strong></div> <div><img src="/SiteCollectionImages/Institutioner/F/Blandade%20dimensioner%20inne%20i%20artikel/Tunde%20Fulop.jpg" class="chalmersPosition-FloatRight" alt="Tünde Fülöp" style="margin:5px;width:215px;height:284px" />“Above all, I really enjoy teaching. It feels a bit like walking on clouds, and I suspect that feeling may be contagious. I do my best to create a relaxed atmosphere, so that the students can feel that they can ask any questions, like in a happy family. My aim is that it should feel like a dialogue between me and the students. It does not always work out like that, but this group of students was really fantastic.”</div> <div><br /></div> <div>“One way to make my lectures more personal is to tell anecdotes about the scientists that are relevant for the material. I am a bit of a science history nerd, knowing about how the subject developed and who have been involved is a way for me to understand the big picture. But beyond the pedagogical value, I think it is a lot of fun to share such information. <span style="background-color:initial">To become a physicist is a journey and it is much more fun if you get to know your travel companions, whether they are dead or alive.”</span></div> <div><br /></div> <div><strong>Were there any challenges in teaching the course during the pandemic, and if so, how did you address them?</strong></div> <div><span style="background-color:initial">“</span><span style="background-color:initial">We were lucky in that sense. Almost all the restrictions were lifted during that period. I chose to have all activities on campus and booked the largest lecture halls available. In some cases, when students could not attend due to illness, we tried to help them by sending them notes. </span><br /></div> <div>As far as I know, there were no major issues, and the examination showed that the students managed to learn the material.”</div> <div><br /></div> <div><strong>What does teaching and meeting with the students give back to you?</strong></div> <div>“It gives me a lot of joy and strength. There is not much that can compete with the energy that comes from a classroom full of interested students. Something magical happens there and it is hard to explain that to outsiders. As a physicist, I think of resonance phenomena, but it is better than that, it is not something that happens just then and there, the feeling remains for a longer time. I still feel happy when I think back to the lectures and students from the fall term.”</div> <div><br /></div> <div><strong>Last but not least, how are you going to celebrate?</strong></div> <div>“I will go to the section dinner on Saturday and celebrate together with the students.”</div> <div><br /></div> <div><br /></div> <div style="font-size:15px">The motivation for the award Guldäpplet 2022 by the Student Board of Physics:</div> <div><em>With her burning interest and inspiring lectures, Tünde has made the course &quot;Vector fields and classical physics&quot; a favourite among many students.
