Green ammonia remains a challenge, but researchers make significant progress

The production of ammonia, essential for fertiliser production, is responsible for almost 1.5% of global carbon emissions. This needs to be greener, which is why researchers have been looking for sustainable alternatives for years.

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.

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.

Inaugural address: machine optimisation key to more efficient logistics system

The processing and transport of materials can be made much more efficient, says TU Delft professor Dingena Schott in her inaugural address, ‘Advancing Transport and Processing: from Model to Impact’. She will deliver her address on 15 November. Her research focuses on the interaction between machines and materials, with a special emphasis on granular materials.

Merging like a human: TU Delft develops new model to help self-driving cars drive socially

Scientists at TU Delft have developed a new model that better describes human behaviour when merging into motorway traffic. Current models often assume that drivers are constantly trying to optimise their behaviour to reach their destination as quickly and safely as possible, but this is not always the case, says postdoctoral researcher Olger Siebinga.

Bachelor students develop model to better understand the chemical process of renewable fuels

A group of TU Delft bachelor students has developed, as part of the students’ minor in Computational Science and Engineering, a new model that accurately predicts the molecular properties of alkanes. This knowledge is crucial for the development of renewable fuels.

Eight leading researchers receive Vidi-grant

NWO has awarded 102 researchers a Vidi grant in total 86,7 million euros. Eight promising TU Delft researchers from the domains Exact and Natural Sciences (ENS), Social Sciences and Humanities (SSH) and Applied and Technical Sciences (ATS) have been awarded. This Vidi grant up to 850,000 euros will enables the laureates to develop an innovative line of research over the next five years and further expand their own research group.

TU Delft innovations on a stamp

PostNL has released a stamp sheet on the occasion of international Stamp Day featuring two innovative and sustainable means of transport developed at TU Delft. The stamps feature alongside King Willem-Alexander, the WASP, a wind-assisted cargo ship and the Flying-V, an energy-efficient aircraft design for long distances.
