Tom Burdyny

Dr. Tom Burdyny Assistant Professor T.E.Burdyny@tudelft.nl Building 58 Van der Maasweg 9 2629 HZ Delft The Netherlands Management Assistant Roos Roeling +31 (0)15 27 82165 M.A.H.Roeling@tudelft.nl twitter instagram The Burdyny Energy Lab in the MECS Group is focused on researching technologies that are capable of replacing current fossil fuel manufacturing routes with processes that use renewable electricity as an input. These technologies use electricity to form chemical bonds (also known as electrocatalysis). At present, our primary research focus is on carbon-dioxide (CO 2 ) electrolysis, which can convert CO 2 into base chemicals such as CO and ethylene. We take a more engineering approach to the research problem and are focusing on a) scaling-up CO 2 electrolyzers in the lab, b) understanding transport related phenomena occurring inside a CO 2 electrolyzer, and c) assessing the potential impact and operation of H 2 O and CO 2 electrolyzers on our global energy infrastructure. The work is embedded within the e-Refinery Institute. Research group Academic background Thomas Burdyny has a mechanical engineering education in the form of a BEng and MASc from the University of Victoria in Canada. He moved to the University of Toronto for his PhD thesis in photocatalytic and electrocatalytic conversion of CO 2 (under Prof. David Sinton), before beginning a postdoctoral fellow at TU Delft in 2018. In 2019 he opened his research group as an Assistant Professor working to advance the performance and scalability of electrochemical technologies. The research mixture of the group is broad and ranges from operando techniques, catalyst development, electrochemical engineering, and transport analysis of electrochemical systems.

Matheus Martinez Garcia

Background I’m a Brazilian PhD candidate. I’ve obtained my Bachelor (2013-2018) and Master (2018) degrees in Mechanical Engineering at UNICAMP, both in numerical simulations (CFD) of multiphase flows. Currently, I’m working on the development of a controlled swirl-flow separator via an experimental approach. Research Optimized Controlled Inline Fluid Separation Petroleum is hardly found pure in nature. Its extraction usually involves large amounts of other components, such as water, gas or solid particles. Currently, around 4 barrels of water are extracted from the wells for each barrel of oil. The oil must be separated from the water to be sent to the refineries, and this is currently achieved by bulky (and extremely expensive) gravitational separators. Cyclones are compact alternatives to separate the phases. However, the high shear stress caused in the oil droplets by the swirling flow inside the element cause their breakup, and may lead to emulsions; conditions that certainly impact the efficiency of the device. A control system is required to adjust the flow conditions inside the separator depending on the upstream conditions to avoid, or at least minimize, such effects. My project is to develop the control algorithm that maximizes the efficiency of an inline swirl separator. To achieve such a goal it is necessary (i) an understanding of the hydrodynamics of the process, and (ii) image the distribution of phases inside the equipment. This will be achieved together with the other (3) students involved in the project. More info about the project can be found in the TOMOCON.eu website.

First-ever imaging of pathogens on lettuce leaves in real-time

Met een groeiende wereldbevolking van meer dan 8 miljard mensen is voldoende voedsel produceren een uitdaging. Nederland is ‘s werelds tweede exporteur van voedsel en verbouwt enorm efficiënt allerlei gewassen. Plantenziektes zoals valse meeldauw zijn echter een veelvoorkomend probleem dat de oogst van de boer flink kan bederven. Delftse wetenschappers hebben voor het eerst een manier ontwikkeld om de infectie in planten real-time te volgen, zonder de plant te hoeven doden. De hiermee opgedane kennis helpt om nieuwe resistente gewassen te kweken met een hogere opbrengst en minder gebruik van pesticiden. Het onderzoek staat nu in Nature Communications.

New LDE trainee in D&I office

Keehan Akbari has started since the beginning of September as a new LDE trainee in the Diversity and Inclusion office. What motivated him to work for the D&I office, what does he expect to achieve during this traineeship? Read the short interview below! What motivated you to pursue your LDE traineeship in Diversity and Inclusion office of the TU Delft? I completed both bachelor's and master's degrees in Cultural Anthropology and Development Sociology at Leiden University. Within these studies, my main area of interest was in themes of inclusion and diversity. After being hired as a trainee for the LDE traineeship, and discovering that one of the possible assignments belonged to the Diversity and Inclusion office, my choice was quickly made. I saw this as an excellent opportunity to put the theories I learned during my studies into practice. What specific skills or experiences do you bring to the D&I office that will help promote inclusivity on campus? I am someone who likes to connect rather than polarize, taking into account the importance of different perspectives and stakeholders. I believe that this is how one can achieve the most in fostering diversity and inclusion. You need to get multiple parties on board to get the best results. What are your main goals as you begin your role here, and how do you hope to make an impact? An important goal for me this year is to get students more involved in diversity and inclusion at the university. One way I will try to accomplish this is by contributing to the creation of D&I student teams. By establishing a D&I student team for faculties, it will be possible to deal with diversity- and inclusion-related issues that apply and relate to the specific department. How do you plan to engage with different (student) communities within the university? Since I am new to TU Delft, the first thing I need to do is expand my network here. Therefore, I am currently busy exploring the university and getting to know various stakeholders. Moreover, I intend to be in close contact with various student and study organizations to explore together how to strengthen cooperation on diversity and inclusion. Welcome to the team Keehan and we wish you lots of success with your traineeship!

Researchers from TU Delft and Cambridge University collaborate on innovative methods to combat Climate Change

For over a year and a half, researchers from TU Delft and the Cambridge University Centre for Climate Repair have worked together on groundbreaking techniques to increase the reflectivity of clouds in the fight against global warming. During a two-day meeting, the teams are discussing their progress. Researchers at Cambridge are focusing on the technical development of a system that can spray seawater, releasing tiny salt crystals into the atmosphere to brighten the clouds. The team from TU Delft, led by Prof. Dr. Ir. Herman Russchenberg, scientific director of the TU Delft Climate Action Program and professor of Atmospheric Remote Sensing, is studying the physical effects of this technique. Prof. Russchenberg emphasizes the importance of this research: "We have now taken the first steps towards developing emergency measures against climate change. If it proves necessary, we must be prepared to implement these techniques. Ideally, we wouldn't need to use them, but it's important to investigate how they work now." Prof. Dr. Ir. Stefan Aarninkhof, dean of the Faculty of Civil Engineering and Geosciences, expresses pride in the team as the first results of this unique collaboration are becoming visible. If the researchers in Delft and Cambridge can demonstrate the potential of the concept, the first small-scale experiments will responsibly begin within a year. This research has been made possible thanks to the long-term support from the Refreeze the Arctic Foundation, founded by family of TU Delft alumnus Marc Salzer Levi . Such generous contributions enable innovative and high-impact research that addresses urgent global challenges like climate change. Large donations like these enable the pursuit of innovative, high-impact research that may not otherwise be feasible, demonstrating how our collective effort and investment in science can lead to real, transformative solutions for global challenges like climate change.

How system safety can make Machine Learning systems safer in the public sector

Machine Learning (ML), a form of AI where patterns are discovered in large amounts of data, can be very useful. It is increasingly used, for example, in chatbot Chat GPT, facial recognition, or speech software. However, there are also concerns about the use of ML systems in the public sector. How do you prevent the system from, for example, discriminating or making large-scale mistakes with negative effects on citizens? Scientists at TU Delft, including Jeroen Delfos, investigated how lessons from system safety can contribute to making ML systems safer in the public sector. “Policymakers are busy devising measures to counter the negative effects of ML. Our research shows that they can rely much more on existing concepts and theories that have already proven their value in other sectors,” says Jeroen Delfos. Jeroen Delfos Learning from other sectors In their research, the scientists used concepts from system safety and systems theory to describe the challenges of using ML systems in the public sector. Delfos: “Concepts and tools from the system safety literature are already widely used to support safety in sectors such as aviation, for example by analysing accidents with system safety methods. However, this is not yet common practice in the field of AI and ML. By applying a system-theoretical perspective, we view safety not only as a result of how the technology works, but as the result of a complex set of technical, social, and organisational factors.” The researchers interviewed professionals from the public sector to see which factors are recognized and which are still underexposed. Bias There is room for improvement to make ML systems in the public sector safer. For example, bias in data is still often seen as a technical problem, while the origin of that bias may lie far outside the technical system. Delfos: “Consider, for instance, the registration of crime. In neighbourhoods where the police patrol more frequently, logically, more crime is recorded, which leads to these areas being overrepresented in crime statistics. An ML system trained to discover patterns in these statistics will replicate or even reinforce this bias. However, the problem lies in the method of recording, not in the ML system itself.” Reducing risks According to the researchers, policymakers and civil servants involved in the development of ML systems would do well to incorporate system safety concepts. For example, it is advisable to identify in advance what kinds of accidents one wants to prevent when designing an ML system. Another lesson from system safety, for instance in aviation, is that systems tend to become more risky over time in practice, because safety becomes subordinate to efficiency as long as no accidents occur. “It is therefore important that safety remains a recurring topic in evaluations and that safety requirements are enforced,” says Delfos.
