Mechanism of Cobalt-Manganese Catalysts Deciphered

Combination of different methods was the key to success

22-Oct-2024 - The energy carrier hydrogen can be obtained from water by electrolysis. This works particularly well with Cobalt spinel electrocatalysts containing manganese. However, it was unclear why. Conventional catalysts for hydrogen production via water electrolysis usually contain precious metals and are ...

A sharper look at the interior of semiconductors

A research team is developing a high-resolution imaging technique that can be used to determine internal structures in materials and their chemical composition in a non-destructive manner and with nanometre precision

19-Feb-2021 - Images provide information – what we can observe with our own eyes enables us to understand. Constantly expanding the field of perception into dimensions that are initially hidden from the naked eye, drives science forward. Today, increasingly powerful microscopes let us see into the cells and ...
