Laboratory for Micro and Nanotechnology (LMN)

Every year, during the winter months, PhD students of the Swiss Nanoscience Institute take part in the SNI: Nano in the snow PhD school. Currently, as COVID-19 is still omnipresent in our everyday it happened virtually this year and Thomas Mortelmans took part. He said: “It was an exciting day filled with excellent scientific content from a variety of research fields; ranging from quantum physics, to protein engineering and drug delivery. During these events, the interdisciplinary of SNI is nicely highlighted and the benefit of joined research projects across scientific disciplines can be seen.”

Thomas gave an interdisciplinary introduction to the field of microfluidics and was awarded with the prize of best talk.

The compounds known as ‘pyrazinacenes’ are simple, stable compounds that consist of a series of connected nitrogen-containing carbon rings. They are suitable for applications in electrochemistry or synthesis, as the researchers describe in the science journal Communications Chemistry. They were first designed, synthesized and chemically characterized in solution by the Hill team and carefully investigated by Scanning Tunneling Microscopy and Surface Chemical Analysis. The compounds have been shown to reversibly release and accept electrons and arrange themselves differently depending on the oxidation state. Interestingly, the oxidation and reduction reactions of the pyrazinacenes are not only affected by a chemical impulse, but can also be stimulated by light so they can be considered photo-redox active.

Thomas A. Jung has been elected as a delegate of the Associate Members of the European Physical Society. As a member he shall contribute to the reviewing of the activities of the Society, the annual accounts and to the discussion of future priorities and new activities.
