Communications Physics. volume 4, Article number: 98 (2021) 

Abstract:
Single crystals of URu2Si2 show below 17.5 K a transition into an ordered state with a significantly reduced entropy. The low temperature phase is called the hidden order (HO) state, because its microscopic origin is still unknown—there are no charge….

Wear. Volumes 466–467, 15 February 2021

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…

Author: Pablo G. Lustemberg, Philipp N. Plessow, Yuemin Wang, Chengwu Yang, Alexei Nefedov, Felix Studt, Christof Wöll, and M. Verónica Ganduglia-Pirovano

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…
