Stephan has been featured in a nice booklet published by the Kyoto University, in which 125 of their promising researchers could say a few words about their own work to the broad public. It is an interesting effort on scientific communication. This booklet can be found by clicking here, and Stephan's article is shown in page 34.
This is the picture of Stephan in the booklet, featuring him in his office, the stage for his Igor Pro magic.

Bernd Winter awarded - December 2024
For the invention of liquid jet photoelectron spectroscopy, the Innovation Award on Synchrotron Radiation 2024 was bestowed to Bernd Winter. He received the prestigious award together with Manfred Faubel from Max-Planck-Institut für Strömungsforschung (now Max-Planck-Institut für Dynamik und Selbstorganisation) in Göttingen. The award was presented in a ceremony framed by the BESSY Users’ Meeting. See here for our press release.

Beamtime @ SOLEIL - Pléiades - February 2024
This February we had another beamtime at the beamline Pléiades located in the synchrotron SOLEIL (Paris). We investigated Photoelectron Angular Distributions (PADs) from liquid micojets and flatjets.
Here we can see the circular facade of the laboratory, as it is typical for synchrotron facilities, and its nice surroundings.

Christmas/New year's party - Jan 2024
We had to postpone the Christmas party in our institute due to a wave of Covid infections. What took place instead was a Christmas + New year's party that began with a retrospective and announcements for 2024 from our director, Gerard Meijer.
The moment all the members from the Molecular Physics department gathered to hear the announcements made by Gerard Meijer can be seen on the left. On the right, a close-up photo of him while one of our latest papers is displayed!

Lab experiments - January 2024
Our friend and collaborator Christian Schewe spent almost two weeks performing experiments in our machine at the FHI, using the He lamp. He likes to study exotic systems such as liquid metal (GaIn and GaInSn alloys) and solutions which solvents aren’t water: acetonitrile, THF and others.
Christian brought his PEEK HPLC pump to avoid exposing our stainless steel pumps to aggressive solutions, or to solvents that don’t go well on water. Here we can see how the inlet filter was after running a ferrocenium tetrafluoroborate solution in acetonitrile.

And here we can see what was collected in our cryogenic catcher and trap after Christian performed some liquid jet photoelectron spectroscopy of ferrocene and ferrocenium solutions in acetonitrile. It’s hard to say if it’s pretty, gross or even scary to imagine having this inside our vacuum chamber!
