Abstract:
PVD coatings have been studied as candidates for erosion protection of carbon fibre reinforced polymers. Thus, multilayer Ti/TiN coating stacks with different thicknesses ranging from 1.5 to 11 μm have been deposited by pulsed…

Phys. Rev. Lett. 125, 256101 – Published 17 December 2020

Abstract:
In ceria-based catalysis, the shape of the catalyst particle, which determines the exposed crystal facets, profoundly affects its reactivity. The vibrational frequency of adsorbed carbon monoxide (CO) can be used as a sensitive probe…
