Energy Portrait: Capturing a Molecule's Moment of Excitement

30-Sep-2024 - Researchers at the University of Regensburg in collaboration with IBM Research Europe - Zurich have found a way to access excited states of single molecules and determine their energies. A very fundamental property of atoms and molecules are the energies, at which electrons can be added to or ...

Small steps for electrons – big steps for the solar cells of the future?

Novel measurement method helps to improve perovskite solar cells in a targeted manner

19-Jul-2024 - Physicists at the University of Regensburg and the University of Oxford are using an ultrafast microscope to reveal how electrons move in a new type of solar cell material. The results provide insights into how the material can be used even more efficiently for photovoltaics. In the search for ...

A novel microscope pins down the miracle of molecular oxygen

Researchers track the first step of the reaction of one single dye pigment with oxygen at unprecedented resolution

26-Jul-2021 - Why is it that the colours of a t-shirt fade over time in the sun? Why do you get a sunburn, and why do the leaves of a tree turn brown in the autumn? These questions all have one theme in common, the interplay between dye pigments and ambient oxygen. Every child learns about this chemical ...

Physicists watch electron transfer in a single molecule

15-Feb-2019 - The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks directly, but rather by their mutual interactions, which are governed by their outer electron shells. Many chemical processes are based on the ...
