04.01.2019:   DAAD Mobility project approved 

Deutscher Akademischer Austauschdienst (DAAD) has approved two years mobility project of the group with the Institute of Physics of the Czech Academy of Sciences in Prague with the title Monodisperse direct-bandgap silicon nanoparticles for advanced optoelectronic and biological applications. Visits of scientists and young researchers from both institutions will be funded to investigate the plasma-based generation of silicon nanoparticles (Kiel) and their optoelectronic properties and interaction with biological substrates. RNDr. Kateřina Herynková is the principal investigator responsible for the research at the Department of Thin Films and Nanostructures of the Czech Academy of Sciences.

20.12.2018:   Tim Donders, physics student  at Eindhoven University,  finshed  internship

From September to December 2018, Tim Donders, a master student in the friendly  group of Job Beckers at Einhoven University of Technology, successfully completed an intership in Kiel. He performed  two dimensional  measurements with electrostatic probes and  video diagnostic of nanodusty plasmas. One focus was the investigation of filaments in  the magnetized plasma of a CCP.  The traces of the filaments in a nanodust cloud (see image)  can be used to  learn about the  scaling of the filaments with the magnetic field.

19.04.2018: New publication

The paper focuses on the reaction mechanisms of plasma-generated oxygen atoms in aqueous solutions. The effluent from a plasma source operated with standard and 18O-labeled O2 gas was used to treat water in the presence of phenol as a chemical probe. Comparing mass spectrometry and gas chromatography-mass spectrometry data of the solutions treated with plasma under normal and labeled oxygen provides clear evidence that O(aq) originating from the gas phase enters the liquid and reacts directly with phenol, without any intermediate reactions. Additionally, the atmospheric-pressure plasma source demonstrates great potential to be an effective source of O(aq) atoms without the requirement for any precursors in the liquid phase.
