New foundation strengthens Dutch Computational Science

Addressing major societal challenges such as clean energy, sustainable food systems, and improved water management increasingly depends on computational science. To strengthen Dutch expertise and innovation in this field, the Computational Science NL Foundation was established on October 15, 2024. The establishment of the Stichting marks a significant milestone for computational science in the Netherlands. This newly established foundation will drive the activities of the Computational Science NL platform , The aim is to strengthen the Dutch computational science knowledge and innovation ecosystem and drive future strategic investments in research, infrastructure, and human capital. The founding members of the board are Johan Mentink (Radboud University), Bianca Giovanardi (TU Delft) , and Linn Leppert (University of Twente), who will be chairman, secretary, and treasurer of the foundation board of directors, respectively. Together with Alfons Hoekstra (University of Amsterdam), Mark Roest (VORTech), and Wil Schilders (TU Eindhoven) they are also part of the Computational Science NL Strategy Board, established earlier this year. CWI, the NWO institute for research in theoretical computer science and mathematics, will serve as the foundation’s seat. National agenda Computational Science The Computational Science NL platform is built on and implements a roadmap outlined in the National Agenda for Computational Science , created by a coalition of Dutch scientists and industry representatives chaired by Kees Vuik, scientific director of the TU Delft Institute for Computational Science and Engineering . The National Agenda was presented to the Ministry of Economic Affairs (EZK) in 2022. This agenda highlights the critical role of computational models and simulations in addressing societal challenges and creating a sustainable future. Arriving at the most sustainable solution with computational power "The problems of our time, such as the transition to a sustainable future, are so complex that it is impossible to solve them with only theory or experiments," professor of Numerical Mathematics Kees Vuik explains. "Indeed: to arrive at a solution in this complex matter, you have to work through countless predictions, and that can only be done with (super-)computers. Take the course of our rivers under a changing climate, for example; you can't test or theorize that. You need models and simulations for that. In other words, Computational Science." Supercomputers The connected computing infrastructure for research and education of the Delft High Performance Computing Centre (DHPC) and supercomputer DelftBlue is available to Delft researchers and students. In addition, there’s of course SURF’s ICT infrastructure, which is vital for computational science professionals to conduct cutting-edge work.

Barrières doorbreken voor geothermische energie

Als Europa de doelstellingen op het gebied van duurzame energie wil halen, is het van belang om het gebruik van aardwarmte op te schalen. Het nieuwe EU gefinancierde consortium FindHeat zal onder leiding van Sebastian Geiger van de TU Delft een innovatieve toolkit ontwikkelen om geothermie efficiënter en duurzamer te exploiteren. Deze ontwikkeling beoogt technische en economische risico’s te verminderen en de steun van burgers te vergroten. TBM onderzoekers Gerdien de Vries en Fabiën Dekker brengen hun expertise in op het gebied van de sociale wetenschap. Momenteel houden technische en economische risico’s grote investeringen in geothermie tegen en ondermijnen het vertrouwen van burgers in deze duurzame energiebron. Het FindHeat consortium gaat een flexibele toolkit ontwikkelen om de drempels voor geothermie te verlagen. De focus van de toolkit is een nieuwe workflow voor de exploratie van aardwarmte waarin innovatieve softwareoplossingen, goedkope geofysische en geologische exploratietechnieken, training op maat en publieke betrokkenheid gecombineerd worden. Validatie op acht geothermie-locaties De nieuwe toolkit zal worden gevalideerd op acht verschillende geothermie-locaties die geologisch gezien van elkaar verschillen. Hier wil het consortium de economische en technische voordelen aantonen bij het verkennen en beoordelen van geothermische bronnen. Door eindgebruikers uit de industrie direct te betrekken kunnen zij helpen bij de ontwikkeling van de toolkit en deze tegelijkertijd toepassen in hun dagelijkse werkzaamheden. Dit geeft betere garantie voor de technische en economische haalbaarheid. Vertrouwen FindHeat omvat uitgebreid sociaal-wetenschappelijk onderzoek waarin gezamenlijk gewerkt wordt aan nieuwe communicatiestrategieën die de betrokkenheid van burgers verbeteren en helpen om meer vertrouwen te creëren. De combinatie van maatschappelijke steun en verlaagde technische en economische risico's zal leiden tot een efficiëntere en duurzamere exploitatie van geothermie. Daarmee draagt het bij aan het behalen van de Europese doelen voor duurzame energie uit aardwarmte. Binnen het consortium onderzoekt TBM hoe lokale culturen de percepties van geothermische energie beïnvloeden en hoe deze kennis kan worden gebruikt om de publieke communicatie te verbeteren. Dit onderzoek moet leiden tot een openbaar beschikbare handleiding voor belanghebbenden (zoals energiebedrijven) die in contact staan met lokale gemeenschappen. Psycholoog Gerdien de Vries: "Met dit cross-culturele onderzoek in acht landen willen we de relatie tussen lokaal sentiment en de publieke communicatie over geothermische energie beter begrijpen." Gerdien de Vries FindHeat consortium In het FindHeat-consortium komen expertise en innovatie uit de industrie en de academische wereld samen op het gebied van geologie, geofysica, techniek, sociale wetenschappen, economie, communicatie en technische training. Het consortium bestaat uit de academische partners ETH Zurich, Imperial College London, Charles University Prague, University of Cologne, Czech Geological Survey en TU Delft. Industriële partners zijn Reykjavik Energy (Orkuveitan), Electricite de Strasbourg, Repsol, Delft Inversion, en TRACS International Ltd. FindHeat is grotendeels gesubsidieerd door de Europese Uni een ontvangt ook subsidies van UK Research and Innovation, Swiss National Foundation, en TU Delft Excellence Foundation.

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.

Een flexibele backstop als deel van de oplossing voor netcongestie

Uit naam van het TU Delft PowerWeb Institute overhandigen onderzoekers Kenneth Brunninx en Simon Tindemans op 12 november 2024 een Position Paper aan de Tweede Kamer, met een mogelijke oplossing voor de grote netwerkcapaciteit-problemen die in Nederland steeds vaker opspelen. Waarschijnlijk haalt Nederland de klimaatdoelen 2030 niet, en dat komt onder andere doordat de grote industrie niet snel genoeg kan overstappen op elektriciteit, mede doordat er steeds vaker problemen ontstaan rondom netwerkcapaciteit en netcongestie. Naar alle waarschijnlijk zullen die problemen dit decennium eerst zelfs toenemen, voordat ze kunnen afnemen, stellen de onderzoekers. De oplossing die de onderzoekers van het TU Delft PowerWeb Institute aanbieden, is de ‘flexibele backstop’. Met een flexibele backstop kan de huidige capaciteit van het elektriciteitsnet efficiënter gebruikt worden zonder aan veiligheid of betrouwbaarheid in te boeten. Een flexibele backstop is een veiligheidsmechanisme dat semiautomatisch en op korte termijn de hoeveelheid elektriciteit vermindert die een elektrische verbruiker van het elektriciteitsnet kan onttrekken (een elektrische laadpaal of een warmtepomp) of leveren (een PV-installatie). Het is een klein apparaatje dat is aangesloten of ingebouwd in een elektrische verbruiker, zoals een laadpaal of warmtepomp, en dat ‘communiceert’ met de distributienetwerkbeheerder. In geval van acute congestie op het netwerk geeft de netwerkbeheerder een signaal aan het apparaat om de hoeveelheid stroom te beperken. Duitsland heeft recent een vergelijkbaar systeem ingevoerd voor elektrische laadpalen. De backstop wordt enkel geactiveerd in periodes van acute congestieproblemen, nadat alle andere maatregelen uitgeput zijn. “Het opwaarderen van het elektriciteitsnetwerk blijft essentieel, maar zal in de praktijk nog jaren duren. Er is dus behoefte aan kortetermijnoplossingen die geïntegreerd kunnen worden in de langetermijnplanning. Wij, de leden van het TU Delft PowerWeb Institute, roepen de overheid, netwerkbeheerders en regulator op om de flexibele backstop als extra veiligheidsmaatregel voor het netwerk te onderzoeken”, aldus de onderzoekers. Het gehele paper is hier te lezen. Kenneth Bruninx is universiteit hoofddocent bij de faculteit Techniek, Bestuur en Management, waar hij met kwantitatieve modellen energiebeleid, regulering en marktontwerp evalueert. Simon Tindemans is universitair hoofddocent in de Intelligent Electrical Power Grids groep van faculteit Elektrotechniek, Wiskunde en Informatica. Hij doet onder andere onderzoek naar onzekerheid en risicomanagement voor elektriciteitsnetwerken. Het TU Delft PowerWeb Institute ontwerpt het elektriciteitsnetwerk van de toekomst.
