Neutralizing electronic inhomogeneity in cleaved bulk MoS₂

Molybdenum disulfide (MoS2) is a highly versatile material that can function, for example, as a gas sensor or as a photocatalyst in green hydrogen production. Although the understanding of a material usually starts from investigating ...

How to protect biocatalysts from oxygen

There are high hopes for hydrogen as the key to the energy transition. A specific enzyme group found in algae and in bacteria can produce molecular hydrogen simply by catalyzing protons and electrons. However, the enzyme ...

What stinks? The role of hydrogen sulfide in the gut

Whoever smelt it dealt it … especially if what's been dealt smells like rotten eggs. The culprit behind that eggy stink is hydrogen sulfide (H2S), a colorless, pungent gas produced by both mammalian and bacterial cells ...

Detection of environmental PFAS by interrupted energy transfer

PFAS, a family of highly fluorinated substances, represent a danger for humans and the environment. Particularly problematic members of this family, such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) ...

Crunch time for Phoebus before testing

Launching things into space is hard. Aside from the engines and software, orbital calculations and the launch pad, the tanks that hold the fuel are a masterful example of engineering in their own right. And ESA will soon ...
