MCEC PhD Dirk Jonker‘ (UT) publication reports on the fabrication and modification of a top-down nanofabrication platform for enormous parallel silicon nanowire-based devices. In they paper the authors explain the nanowire formation in detail, using an additive hybrid lithography step, optimising a reactive ion etching recipe for obtaining smooth and vertical nanowires under a hybrid mask, and embedding the nanowire in a dielectric membrane.

Tenure Track Assistant and Co-Promotor: Freddy Rabouw on supervising Stijn Hinterding’s MCEC Project

Although Freddy Rabouw (UU) is a MCEC tenure track assistant professor and works on various MCEC projects in different roles, this was the first time that he supervised a PhD project from beginning to end. The MCEC Office was curious to know more about his experience!

Freddy Rabouw (UU) receives VIDI-grant

Blue and ultraviolet sunlight are highly energetic. Current technologies to harvest sunlight cannot use this energy efficiently. “Quantum cutting”, the conversion of blue and ultraviolet light into infrared, can change this. Freddy’s project ‘Science: Quantum cutting sunlight with Yb3+-doped perovskite’ will develop strategies for more efficient quantum cutting, which will inspire new technologies for sustainable energy production.

Last year, Rabouw received the Heineken Young Scientists Award in the category Natural Sciences from the Royal Netherlands Academy of Arts and Sciences (KNAW), for his research on new materials to generate light, for example for solar cells or display screens.

Many congratulations Freddy!

Online Lecture Series: Life After MCEC

Dear MCEC Members,

We are happy to invite you to our Online Lecture Series: “Life after MCEC” given by our MCEC members. We encourage you to actively participate and ask any questions through the chat or after the lecture.

Our second lecture will be given by dr. Jeroen Vollenbroek.

Date: Thursday 20/05/2021
Time: 13.00 /13.45 h.

My name is Jeroen Vollenbroek and I am a Postdoctoral researcher at the Nephrology and Hypertension department at the UMC Utrecht and also partially at the University of Twente. I did my bachelor and master in Electrical Engineering at the University of Twente. During my PhD within MCEC I worked on a multidisciplinary, highly collaborative project at the BIOS Lab-on-a-Chip group (University of Twente) and the Inorganic Chemistry and Catalysis group (Utrecht University). I worked together with Anne-Eva Nieuwelink on developing microreactors for the high-throughput activity screening (and sorting) of catalyst particles. During my MCEC project I could apply the knowledge I learned during my master and simultaneously learn a lot about chemistry and catalysis through the collaboration. Now, for my postdoc I am part of a long running project in developing a portable artificial kidney. My project focusses on the removal of urea from dialysate using electro-oxidation. During my talk/lecture I will tell about my experiences within MCEC, how MCEC helped me become the researcher I am, and a bit about my current project.


MCEC Members: Experienced Escapers

On Friday April 9th, MCEC’s C-Team organized a really fun, informal Remote Teambuilding Experience. It was an online escape room hosted by The Box Company.

The participants were divided into 5 teams of 5 people.

In the end Team Argon turned out to be the quickest to escape. Congratulations to Roy Hoitink, Ketki Srivastava, Juan Guillermo Ramírez, Mathieu Odijk and Jochem van Duin!
