The selection process following the PhD Call for MCEC’s second phase has started. At Utrecht University, MCEC members Florian Meirer and Freddy Rabouw, Program Coordinator Nina Versteeg and Hannie van Berlo-van den Broek (ARC CBBC) came together to discuss the first round of candidates. Since our PhD Call received almost 900 submissions, we expect these discussions to continue well into December. Naturally, candidates will be informed as soon as possible. We wish our committees in Utrecht, Eindhoven and Twente as well as all the candidates every success!

A breath test instead of a blood test. That’s how much easier it is to use the test for industrial catalysts developed by chemists at Utrecht University. The test uses fluorescent molecules to literally show whether catalyst 1, 2, or 3 works better than the others. This makes it much easier to work on improving the catalysts, which allows production processes in the chemical industry to become increasingly more sustainable. The researchers, under the leadership of Prof. Bert Weckhuysen, will publish their results in Nature Chemistry of 5 November.

In their research, the chemists from Utrecht studied the sustainable production of methanol, one of the building blocks for products such as plastics. Sustainable methanol can be synthesised from CO₂ and hydrogen gas produced using wind- or solar energy or household waste. The catalyst is needed to ensure that the reaction produces as much methanol and as few by-products as possible, at the ideal temperature. The catalyst’s composition and porousness are important aspects of the process, but so is its shape.

During the MCEC-KNAW symposium last December, a group of environmental activists protested the presence (and invitation) of Shell. Bert Weckhuysen was interviewed by online magazine Down to earth (‘platform for green journalism’) for their column ‘Onder vuur’ (‘Under attack’), in which people or organisations who have been under attack for their green ambitions or promises (or lack thereof) , are given the opportunity to respond to the criticism.

“During the conversation [with the protesters] it became clear that we have the same goal: the transition to a sustainable society. But we take on different roles. I conduct research into alternative energy sources and try to help reduce the pollution of fossil fuels as much as possible. Fossielvrij [Fossil-free] wants to emphasize the urgency of change. That’s something I can appreciate.”

In October, November and December, three MCEC PhDs will defend their PhD dissertations: Ivan Devic (UT, 26 Oct.), Jiangtao Lu (TU/e, 19 Nov.) and Robin Geitenbeek (UU, 19 Dec.). We asked them about their research, their time at MCEC and of course and the contents of their dissertation. You can read their responses below. We wish Ivan, Jiangtao and Robin all the best and good luck with their defence! 

Ivan Devic: Wetting and dewetting effects of bubbles, droplets and solids

Could you tell us a little more about your dissertation?
The present dissertation explores many morphological properties of bodies in the presence of capillary interactions (surface tension). We obtain stable bubble/droplet shape by minimizing its interfacial energy, which in a case of a patterned substrate gets mathematically complicated. Throughout the thesis we have used many experimental and numerical techniques. Since the field itself is still very multidisciplinary, we’ve realised many collaborations as well.”

How do you look back on your time as a MCEC PhD?
I consider myself very lucky that I got to be part of the “first MCEC generation”, since I really enjoyed spending time with my MCEC peers on our project meetings.  Even though there were too many meetings in my opinion, I never got tired of my fellow PhDs.

What is your biggest motivation?
I wish I knew.
[Excerpt from the 2016 MCEC PhD Interview for the internal newsletter.]

Have you found your biggest motivation yet?
Yes, I have. It is to use all the education obtained, to control my life; not the other way around.

What’s next?
The complete net sum of my plans are as follows: go back home, and relax. I’ve decided to take a breather before embarking on new adventures.

Jiangtao Lu: Direct numerial simulation of couled heat and mass transfer in dense gas-solid flows with surface reactions

Could you tell us a little more about your dissertation?
An efficient ghost-cell based immersed boundary method is developed to perform direct numerical simulation of coupled heat and mass transfer problems in fluid-particle systems, which provides insights in the interplay among mass transfer, chemical transformations and heat effects.

• Please find the thesis summary here.

What, to you, is the most important result from your research?
It is the first time in the research of chemical engineering that the immersed boundary method is applied to modeling of realistic catalytic reaction processes.

How do you look back on your time as a MCEC PhD?
MCEC is well organized. The autumn school every year consists both knowledge-learning and fun-enjoying. MCEC also encourages collaboration, which provides me a chance to produce a joint paper.

What do you enjoy the most about your research?
Some innovative technique never done by other people before.
[Excerpt from the 2015 MCEC PhD Interview for the internal newsletter.]

Is that still the case?
Doing something innovative has indeed been the most exciting thing during my PhD research. As I focus on modelling, writing codes and finding bugs are permanent challenges and I always enjoy those.

What’s next?
Throughout my PhD years, I found my personality is more suitable for academia. I study, and think about problems quietly, and then merge myself into the process of solving a problem. But industry requires a more outward personality, which means fast but superficial solutions, good talking skills and interacting with a lot of different people all day long. It’s something I can do, of course, but it requires changes and it might not be comfortable for me. So, I’ll probably stay in academia. In the following years, I will do a PD at ARC CBBC.

Robin Geitenbeek: Luminescence Thermometry: Fundamentals and Applications

Promotors: Prof. Andries Meijerink, Prof. Bert Weckhuysen and Prof. Alfons van Blaaderen

More information & location (t.b.a.)

Could you tell us a little more about your dissertation?
My dissertation is about monitoring temperature by looking at light. We have prepared special nano- and microparticles that have temperature-dependent luminescence. By monitoring this luminescence using light microscopy we have been able to determine temperatures up to 900 K with a spatial resolution of up to at least 10 µm.

Looking back at your research, what are you most proud of?
The thing I am most proud of is the fact that a lot of people are now using the technique that I developed in Utrecht. Some of the showcases performed in my dissertation were done to demonstrate the potential of Luminescence Thermometry. However, there are also chapters in my thesis in which the research started with a problem statement and I helped by performing measurement to clarify the strange results. It seems it’s really applicable!

How do you look back on your time as a MCEC PhD?
I had a lot of fun in the MCEC group. For me, there has been added value. I enjoyed my time in Team Community, during the annual meetings and especially the social activities with my fellow MCEC colleagues.

Now that you’re (almost) done, have there been other things that you found enjoyable? Or is there maybe a different scientist or historical figure you’d like to offer a beer?
I also enjoyed writing my thesis and articles. Although it can be tedious, it also gives a lot of satisfaction once a work is finished, submitted, peer-reviewed, rewritten and finally accepted! I guess in that sense I would like to enjoy a beer now with the person who invented coffee as a drink. Really started to appreciate that more the last few months of writing!

So now that you can’t put off thinking about the future any longer (see final question in the 2016 interview), have you been able to make a well-balanced decision yet?
I actually already partially answered this question during the previous interview! I was really still in doubt what I wanted to do. I have thought about teaching and I followed some courses on this topic. However, I think I would be bored too fast with a pure teaching job. I think my new job still needs to have an element of research in there. I prefer to stay at the University (although I don’t think I would like to do a post-doc) and otherwise a job as scientist in a research institute or company also sound very appealing!

We are very pleased to announce that Detlef Lohse will be awarded the prestigious Balzan Prize 2018 for his fluid dynamics research. The price, of 750,000 Swiss Francs, will be awarded during an official ceremony in Rome, in November.

Hello members of the MCEC Community,

My name is Daan van Arcken. I have recently joined the MCEC office in Utrecht as Communications Assistant. Before this, I worked as a bike messenger for De Fietskoerier Utrecht. I actually still do that part-time now.

Next to riding my bike, I’ve enjoyed working at many different companies doing many different things. For example, at Kugler Publications I was in charge of the digital publication process. I made sure deadlines were met, in-text citations referred to actual sources and the result looked somehow professional in the end.

My role at the MCEC Office will be to assist the program coordinator Nina and communications officer Christine. I am very enthusiastic about joining the MCEC team. I’ve already had the chance to meet some of the research group in Utrecht and I look forward to visiting Eindhoven and Enschede soon.

If you have any questions, want to go out for a bike ride or talk about music feel free to contact me at d.r.vanarcken@uu.nl or via LinkedIn.

MCEC is looking for highly motivated and creative PhD candidates in the fields of Chemistry, Physics and/or Engineering, who aspire to jointly and multidisciplinary address one of the grand challenges of today: sustainable energy conversion.

Please visit this page for more information (temporarily also accessible via the menu above, via Home).

The NWO Domain Applied and Engineering Sciences had granted Emiel Hensen (TU/e) with a Take-off proposal grant for Vertoro. This start-up valorises the catalytic process for lignin depolymerisation, as developed bij Emiel Hensen and his team at Eindhoven University of Technology.

Lignin is a waste stream of bioethanol plants and paper mills. Vertoro, a spin-off of the InSciTe consortium Emiel Hensen is board member of, aims to scale up the above mentioned chemical process, to produce a so-called crude lignin oil (CLO). This oil will then serve as platform for resins, chemicals and fuels – just like fossil crude oil, but made out of waste.  At the start of 2019, a pilot plant will be ready at Brightlands Chemelot Campus in Geleen.

We congratulate Emiel Hensen and his team on this award!

You can read more about Vertoro and/or InSciTe here.
