Excitation of robust materials

Kiel physics team observed extremely fast electronic changes in real time in a special material class

10-Jul-2020

In physics, they are currently the subject of intensive research; in electronics, they could enable completely new functions. So-called topological materials are characterised by special electronic properties, which are also very robust against external perturbations. This material group also ...

Boron nitride destroys PFAS 'forever' chemicals PFOA, GenX

Pollutant-destroying properties surprise Rice engineer: ‘It’s not supposed to work’

10-Jul-2020

Rice University chemical engineers found an efficient catalyst for destroying PFAS "forever" chemicals where they least expected. "It was the control," said Rice Professor Michael Wong, referring to the part of a scientific experiment where researchers don't expect surprises. The control group is ...

New light-based method for faster and 'green' production of building blocks for medicines

"Significant breakthrough" simplifies processing of gaseous, low-weight hydrocarbons in industry

07-Jul-2020

In industry, gaseous hydrocarbons, such as ethane and methane, are frequently changed into molecules that can act as building blocks for pharmaceuticals and agrochemicals. Typically, these processes take place at high temperatures and pressures, and can also produce large amounts of pollutants. ...
