‘Do you also make money as a professor?"

During ‘Meet the Professor’, four 3mE professors visited several Delft primary schools. They gave fifth and sixth grade pupils guest lessons dressed in togas.

Visualising internal stresses in solid polymers using colour-changing Spiropyrans

Spiropyrans are chemicals that change colour when you shine light on them – a useful property in many areas of medicine and technology. Now Georgy Filonenko and his colleague, Richard Janissen at the Faculty of Applied Science have discovered a new use for these so-called photochromic molecules - visualising stresses in solid polymers. Their research is published in the ‘Journal of the American Chemical Society.’

New methods to investigate the interface between biomaterials and cells to help regenerate body tissues

Lidy Fratila-Apachitei and Murali Ghatkesar received a Cohesion grant to investigate how 3-D printed pillars with features in the sub-micrometre range can affect adhesion and mechanics of living progenitor cells at single cell level. Together with postdoc researcher Livia Angeloni and the other collaborators, they developed and applied a novel method based on fluid force microscopy.

In Memoriam Anton Paardekooper (1967-2022)

Anton Paardekooper passed away completely unexpectedly on 27 December 2022. Anton was a project lecturer at our faculty for six years. While studying mechanical engineering, he was a board member of Leeghwater.

Joost de Winter appointed Professor of Cognitive Human-Robot Interaction

De Winter’s research focuses on touchless interaction between robots and humans so that in the future, robots can read and understand the intentions and instructions of humans in their vicinity by means of eye-tracking and other sensors. And robots, in turn, will be able to adapt their functioning to communicate their own intentions both to nearby humans and other robots. The vision is to contribute to a future in which humans and robots share cognitive processes and adapt to each other.

EU Funds SeaClear2.0 for more underwater robots to collect heavier seafloor litter

Following the success of SeaClear1, which showed that a system of autonomous robots can detect and remove litter from the seafloor, the European Union’s Horizon Europe programme has awarded a second project, SeaClear2.0, nearly 8 million euros to extend the use of multiple robots working together to identify and collect even heavier objects from deeper seas.

3mE wins both second and fourth place in Best Tech-idea 2022

3mE researchers won second and fourth place in the Best Tech-idea 2022 competition run by Dutch science magazine, ‘KIJK’. Second place was awarded to Willem Haverkort for his work on hydrogen-production using membraneless electrolysis and fourth place goes to Farbod Alijani for his research on the use of graphene in detecting antibiotic resistant bacteria. More efficient hydrogen production Hydrogen-production by Electrolysis without using a membrane is an idea that won 3mE’s Willem Haverkort second prize in the ‘Best Tech-idea 2022’ competition run by the popular Dutch science magazine, ‘Kijk.’ “In electrolysis you make hydrogen and oxygen by applying a voltage to a salt-water mixture between two electrodes,” explains Haverkort. “This produces hydrogen at one end, and oxygen at the other end and usually there’s a membrane to stop them mixing and forming an explosive gas.” But using a membrane reduces energy efficiency by increasing resistance. So Haverkort has developed a different way to keep the hydrogen and oxygen separate using a flow system: “You make the water flow through the electrodes in opposite directions, so that the gases move away from each other without fear of them mixing.” This means that you can place the electrodes much closer together, reducing the resistance by a factor of ten, meaning more hydrogen for less energy and at lower costs.

(Willem) Haverkort +31 15 27 86651 J.W.Haverkort@tudelft.nl Using graphene to listen to bacteria 3mE’s Farbod Alijani also appeared in the ‘Best Tech-idea 2022’ listing, coming in at fourth place, for his work on the use of graphene to ‘listen to bacteria’ in order to detect whether or not they are still living. Graphene is a form of carbon made up of extremely thin layers - just one-atom thick - which are very sensitive to external forces. By making a sort of ‘drum-skin’ of graphene, Alijani has been able to detect the tiniest of sounds, including the vibrations of a single living bacterium. This device can therefore be used to tell whether bacteria are still alive or not, which has great potential for health care in helping scientists detect which types of bacteria are antibiotic resistant and which are not.

Nastaran Barin has developed a promising tool for studying brain cancer mechanobiology

Understanding the mechanobiology of glioma cells is of paramount importance for prospective treatment screening of this brain tumour. Nastaran Barin and Angelo Accard developed, in a joint effort with Erasmus MC, biomimetic 3D structures via two-photon polymerization and cultured therein patient derived glioma cells.
