Happy Holidays and a good start into 2023

Christmas Card 2022

Happy holidays and merry christmas to those who celebrate from the whole IMC Team. It has been a productive and successful year with over 20 publications, many conferences and recently two excellent PhD defenses. A big thank you to all of our friends, colleagues and collaborators.
Stay healthy and see you all in 2023!

A first binational PhD in the IMC Group. PhD Defense of David

David PhD Defense

We are proud of David who successfully defended his thesis on 15.12.2022 and obtained a binational PhD which he deserved for his outstanding achievement. The defense was held in a hybrid format. The examiners that were present in person included Prof. Sean Barry (Carleton University, Canada), Prof. Erwin Kessels (TU/E, Eindhoven, The Netherlands), Prof. Peter Awakowicz (AEPT, RUB) and Prof. Anjana Devi (RUB). The defense was chaired by Prof. Raphael Stoll. Other examiners from Carleton University namely Prof. Anatoli Ianoul and Prof.Reza Kholghy with Prof. Robert Burk being the co-chair of the defense participated via Zoom.
David’s performance was outstanding. David has 25 peer reviewed publications to his name which is an extraordinary performance. Given, that this thesis defense was the first of its kind to adhere to the examination rules from both participating universities, it was a unique and challenging experience for the candidate as well as the examiners. Hats off to David for his commendable efforts!

New Publication in Small

2022 has been yet another difficult year due to the pandemic. But it has also been extremely productive with several peer reviewed publications in high impact factor journals. The latest one for this year is a new publication in Small with our collaborators from Bielefeld University and Yale University on 2D-SiO2 membranes. We are very excited to collaborate with Petr, Eric and their respective teams on 2D materials. Thanks to the funding from the DFG for the PHANTOM project.
2D silicon dioxide membranes – The PHANTOM collaboration strikes again!
In our recent collaboration with Dr. Petr Dementyev from Bielefeld University and Prof. Eric Altman from Yale University, we continued our studies on two-dimensional SiO2 membranes for molecular separation of condensable species such as linear and branched alcohols versus inert gases. By combination of experimental and theoretical methods it was shown that freestanding silica bilayers with their well-defined pores facilitate an adsorption-mediated transport mechanism – the origin of perm-selectivity towards vaporous substances. With this work we illustrate that size exclusion in inherent 2D membranes is equally important to chemical affinity for specific separation applications. You can read about this exciting work here

PhD Defense of Nils

Nils PhD Defense

On Thursday (08.12.2022), Nils Boysen successfully defended his PhD thesis. Based on his excellent presentation on new precursors for spatial ALD and CVD of metals, followed by the oral exam, Nils could successfully convince the examination team of Prof. Thomas Riedl (University of Wuppertal), Prof. Maarit Karppinen (Aalto University, Finland) and Prof. Anjana Devi (RUB). The exam was chaired by Prof. Nils Metzler-Nolte (RUB). The committee decided to award Nils a Distinction for his PhD. Congrats from all your IMC team members for this great achievement! This is the first defense held in person after a period of two years in our group.

New Publication in Eur. J. Mass Spectrometry

Electron impact mass spectrometry (EI-MS) is a valuable tool to characterize CVD/ALD precursors and it typically provides the molecular mass as well as decomposition pattern of precursors to elaborate on the stability of the molecules in the gas phase. However, for unstable and reactive precursors, EI-MS reaches its limits. As a promising alternative, liquid injection field desorption (LIFDI)-MS can reliably determine the masses of the molecular ions due to its very soft nature of ionization. In our new publication in Eur. J. Mass Spectrometry, we highlight the advantages of LIFDI-MS for characterizing labile and reactive CVD and ALD precursors.
