Introduction Jasper Verschuur: New Team Member Climate Safety & Security Research Center

Welcome to Our New Assistant Professor: Jasper Verschuur We are thrilled to announce that Jasper Verschuur has joined our team as an Assistant Professor in Engineering Systems & Climate Security. Jasper will be playing a pivotal role within the Climate Safety & Security Research Center, within the Flagship 'Human Security and Liveable Environment.' “I joined the center as it offers a unique interdisciplinary environment to do research on some of the most pressing challenges that society faces in terms of rapidly decarbonising society, as well anticipating the adverse consequences of climate change. Moreover, the center provides a much-needed bridge to align TU Delft research with the needs of policymakers working on climate safety and security issues.” Research Focus and Objectives Jasper’s research addresses the systemic risks that climate change poses to infrastructure systems and the essential services they provide. This work spans both localized levels (e.g., household essential services) and a global scale (e.g., staple food flows). These systemic risks are complex and challenging to quantify due to the interdependencies between human, infrastructure, and economic systems. His research focuses on developing new modelling tools to better anticipate these risks and propose solutions to enhance resilience. This demands a forward-looking approach which not only tries to understand the various impacts of a changing climate, but also the evolving nature of the systems themselves, for instance due to the energy transition and rapid urbanization. This holistic perspective is crucial for devising effective strategies to mitigate systemic risks. Impact for a better society Aligned with TU Delft’s slogan, "Impact for a Better Society," Jasper's research aims to identify and address systemic risks that could lead to societal disruptions or economic losses. He focuses on ensuring that climate change does not exacerbate existing societal inequalities, particularly in the Global South, where these disparities are most pronounced. His work often includes a development angle, striving to assist those most vulnerable to climate risks. TU Delft’s mission in The Hague The mission of the TU Delft campus in The Hague is to bridge the gap and facilitate dialogue between engineering, sciences, and public policy. How can the newly established Climate Safety & Security Research Center contribute to this goal? “I see the research center as the central location to bring different people together and jointly discuss how the research center, and The Hague as a city, can make a difference in dealing with climate change.” In The Hague, there is a vibrant community of policymakers, think tanks, NGOs, and practitioners dedicated to safety and security issues. Climate change is increasingly recognized as a significant security threat. Jasper’s research is crucial for informing the decisions of those working on these challenges daily. In his near future endeavours, he aims to engage with the community in The Hague, understanding their primary challenges and collaborating to find solutions. We are excited to have Jasper on board and look forward to the significant contributions he will make to our community and beyond. Welcome, Jasper!

Students Amos Yusuf, Mick Dam & Bas Brouwer winners of Mekel Prize 2024

Master students Amos Yusuf, from the ME faculty (Mick Dam, from the EEMCS faculty and graduate Bas Brouwer have won the Mekel Prize 2024 for the best extra scientific activity at TU Delft: the development of an initiative that brings master students into the classroom teaching sciences to the younger generations. The prize was ceremonially awarded by prof Tim van den Hagen on 13 November after the Van Hasselt Lecture at the Prinsenhof, Delft. They received a statue of Professor Jan Mekel and 1.500,- to spend on their project. Insights into climate change are being openly doubted. Funding for important educational efforts and research are being withdrawn. Short clips – so called “reels” – on Youtube and TikTok threaten to simplify complex political and social problems. AI fakes befuddle what is true and what is not. The voices of science that contribute to those discussion with modesty, careful argument and scepticism, are drowned in noise. This poses a threat for universities like TU Delft, who strive to increase student numbers, who benefit from diverse student populations and aim to pass on their knowledge and scientific virtues to the next generation. It is, therefore, alarming that student enrolments to Bachelor and Master Programs at TU Delft have declined in the past year. Students in front of the class The project is aimed to make the sciences more appealing to the next generation. They have identified the problem that students tend miss out on the opportunity of entering a higher education trajectory in the Beta sciences – because they have a wrong picture of such education. In their mind, they depict it as boring and dry. In his pilot lecture at the Stanislas VMBO in Delft, Amos Yusuf has successfully challenged this image. He shared his enthusiasm for the field of robotics and presented himself as a positive role model to the pupils. And in return the excitement of the high school students is palpable in the videos and pictures from the day. The spark of science fills their eyes. Bas Brouwer Mick Dam are the founders of NUVO – the platform that facilitates the engagement of Master Students in high school education in Delft Their efforts offer TU Delft Master Students a valuable learning moment: By sharing insights from their fields with pupils at high school in an educational setting, our students can find identify their own misunderstandings of their subject, learn to speak in front of non-scientific audiences and peak into education as a work field they themselves might not have considered. An extraordinary commitment According to the Mekel jury, the project scored well on all the criteria (risk mitigation, inclusiveness, transparency and societal relevance). However, it was the extraordinary commitment of Amos who was fully immersed during his Master Project and the efforts of Brouwer and Dam that brought together teaching and research which is integral to academic culture that made the project stand out. About the Mekel Prize The Mekel Prize will be awarded to the most socially responsible research project or extra-scientific activity (e.g. founding of an NGO or organization, an initiative or realization of an event or other impactful project) by an employee or group of employees of TU Delft – projects that showcase in an outstanding fashion that they have been committed from the beginning to relevant moral and societal values and have been aware of and tried to mitigate as much as possible in innovative ways the risks involved in their research. The award recognizes such efforts and wants to encourage the responsible development of science and technology at TU Delft in the future.

New catheter technology promises safer and more efficient treatment of blood vessels

Each year, more than 200 million catheters are used worldwide to treat vascular diseases, including heart disease and artery stenosis. When navigating into blood vessels, friction between the catheter and the vessel wall can cause major complications. With a new innovative catheter technology, Mostafa Atalla and colleagues can change the friction from having grip to completely slippery with the flick of a switch. Their design improves the safety and efficiency of endovascular procedures. The findings have been published in IEEE. Catheter with variable friction The prototype of the new catheter features advanced friction control modules to precisely control the friction between the catheter and the vessel wall. The friction is modulated via ultrasonic vibrations, which overpressure the thin fluid layer. This innovative variable friction technology makes it possible to switch between low friction for smooth navigation through the vessel and high friction for optimal stability during the procedure. In a proof-of-concept, Atalla and his team show that the prototype significantly reduces friction, averaging 60% on rigid surfaces and 11% on soft surfaces. Experiments on animal aortic tissue confirm the promising results of this technology and its potential for medical applications. Fully assembled catheters The researchers tested the prototype during friction experiments on different tissue types. They are also investigating how the technology can be applied to other procedures, such as bowel interventions.

A key solution to grid congestion

On behalf of the TU Delft PowerWeb Institute, researchers Kenneth Brunninx and Simon Tindemans are handing over a Position Paper to the Dutch Parliament on 14 November 2024, with a possible solution to the major grid capacity problems that are increasingly cropping up in the Netherlands. The Netherlands is unlikely to meet the 2030 climate targets, and one of the reasons for this is that large industry cannot switch to electricity fast enough, partly because of increasingly frequent problems around grid capacity and grid congestion. In all likelihood, those problems will actually increase this decade before they can decrease, the researchers argue. The solution offered by the TU Delft PowerWeb Institute researchers is the ‘flexible backstop’. With a flexible backstop, the current capacity of the power grid can be used more efficiently without sacrificing safety or reliability. A flexible backstop is a safety mechanism that automatically and quickly reduces the amount of electricity that an electric unit can draw from the grid (an electric charging station or a heat pump) or deliver (a PV installation). It is a small device connected or built into an electrical unit, such as a charging station or heat pump, that ‘communicates’ with the distribution network operator. In case of extreme stress on the network, the network operator sends a signal to the device to limit the amount of power. Germany recently introduced a similar system with electric charging stations. The backstop would be activated only in periods of acute congestion problems and could help prevent the last resort measure, which is cutting off electricity to users. ‘Upgrading the electricity network remains essential, but in practice it will take years. So there is a need for short-term solutions that can be integrated into long-term planning. We, the members of the TU Delft PowerWeb Institute, call on the government, network operators and regulator to explore the flexible backstop as an additional grid security measure,’ they said.
