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.

Structure and properties of stacking faulted A15 tungsten thin films

Yaogen Shen, +1 more
- 01 Jan 2001 - 
TL;DR: In this paper, a combination of energy-filtered electron diffraction, x-ray photoelectron spectroscopy, electron energy loss spectrograms, field-emission scanning electron microscopy, and x- ray diffraction is used to establish that oxygen impurities incorporated in the tungsten films prepared by magnetron sputtering play a dominant role in the formation of the stacking faulted A15 W structure.

Controlled nanostructuration of polycrystalline tungsten thin films

Baptiste Girault, +6 more
- 07 May 2013 - 
TL;DR: In this paper, the effect of tungsten sublayers' thicknesses on film composition, residual stresses, and crystalline texture evolution has been established, and the texture development of α-W phase with two texture components is shown to be the result of a competition between crystallographic planes energy minimization and crystallographic orientation channeling effect maximization.
