Atomistic mechanisms for frictional energy dissipation during continuous sliding

Publikováno v: Scientific Reports, Vol 11, Iss 1, Pp 1-10 (2021)

Abstract After more than a century of detailed investigations into sliding friction, we have not arrived yet at a basic understanding of energy dissipation, even for the simple geometry of a rigid slider moving over a perfectly periodic counter surfa

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)

Although hydrodesulfurization is a key process in the chemical industry, a deep understanding of the catalyst structure under real reaction conditions is lacking. Here, the authors combine theoretical calculations with high-pressure scanning tunnelin

Observing the oxidation of platinum

Autor: Matthijs A. van Spronsen, Joost W. M. Frenken, Irene M. N. Groot

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-7 (2017)

Improving platinum as an oxidation catalyst requires understanding its structure under catalytic conditions. Here, the authors discover that catalytically important surface oxides form only when Pt is exposed to high pressure and temperature, highlig
