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 ...

Looking at the Sides of Molecules: Lateral force microscopy reveals previously unseen hydrogen atoms

The ability to directly observe hydrogen atoms marks a significant breakthrough and opening up new avenues for research and innovation

23-Jan-2024 - Researchers at the University of Regensburg and the Graz University of Technology have shown that hydrogen atoms at the sides of molecules lying on a surface can directly be seen. The study, published in the journal “Proceedings of the National Academy of Sciences”, describes that by looking ...

A novel microscope operates on the quantum state of single electrons

08-Dec-2023 - We, and everything around us consists of molecules. The molecules are so tiny that even a speck of dust contains countless of them. The more fascinating it is that nowadays it is routinely possible to precisely image such molecules with a microscope called atomic force microscope. It works quite ...

Unpacking the smart way

How Incoming adenoviruses change their chromatin structure for efficient gene expression

05-Sep-2023 - Adenoviruses, known for their low pathogenicity and technological approachability, have become instrumental in many therapeutic applications, including as vaccination vector platform during the recent SARS-CoV-2 pandemic. Central to their efficacy is the remarkably efficient delivery and ...

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 ...

Slow-motion movies of tiny nanostructures

Researchers developed a novel microscope

07-Oct-2014 - Physicists from the University of Regensburg have developed a novel microscope that allows them to record slow-motion movies of tiny nanostructures with groundbreaking time resolution – faster even than a single oscillation cycle of light. With their new microscope they have directly imaged the ...
