Metal-semiconductor oxide (WO3@W) induces an efficient electro–photo synergistic catalysis for MOR and ORR

Zhongshui Li, +5 more
- 15 Jun 2021 - 
TL;DR: In this article, the oxide-derived metal nanostructures (M-MOx) were used to construct WO3@W in situ to ensure the close contact at the interface between W and WO 3, resulting in the unique two contact modes (Ohmic contact between X and Y and Schottky contact between Pt and X) in Pt-WO3-@W/graphene (simplified as PtwO3/W/GNs).

Hydrogen accumulation in nanostructured as compared to the coarse-grained tungsten

Raquel González-Arrabal, +7 more
- 01 Oct 2014 - 
TL;DR: In this paper, the influence of sample microstructure and of irradiation conditions on the H behavior in Tungsten (W) was investigated, where commercial coarse grained (CGW) and nanostructured W (NW) samples were implanted with (i) H at room temperature (RT), (ii) C and H at RT, and (iii) simultaneously (co-implanted) with H and C at RT.

Low-stress W/Cr films for SCALPEL® mask scattering layers

David L. Windt
- 05 Aug 1999 - 
TL;DR: In this paper, the authors describe the development of low-stress W/Cr bilayer films, for use as SCALPEL® mask scattering layers, which are produced by dc magnetron sputtering in argon, and consist of 25-50-nm-thick W layers deposited onto 5-10-nthick Cr layers.
