Influence of grain boundaries on the radiation-induced defects and hydrogen in nanostructured and coarse-grained tungsten

G. Valles, +9 more
- 01 Jan 2017 - 
TL;DR: In this paper, the influence of grain boundaries (GBs) on the radiation-induced defect evolution and on H retention at 300 K, both experimentally and by computer simulations, was studied.

Hydrogen diffusion and trapping in nanocrystalline tungsten

Pablo M. Piaggi, +8 more
- 01 Mar 2015 - 
TL;DR: In this article, the hydrogen behavior in nanocrystalline W (ncW) samples with grain size of 5 and 10nm was studied using Molecular Dynamics (MD) with a bond order potential (BOP) for the W-H system.

The influence of high grain boundary density on helium retention in tungsten

G. Valles, +5 more
- 01 Feb 2015 - 
TL;DR: In this paper, the influence of a high grain boundary density on the amount, size and distribution of defects produced by pulsed helium (625 keV) irradiation in tungsten has been studied.

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.

Internal stresses in titanium, nickel, molybdenum, and tantalum films deposited by cylindrical magnetron sputtering

John A. Thornton, +1 more
- 01 Jan 1977 - 
TL;DR: In this article, Hoffman et al. measured the internal stresses in thin sputtered films of Ti, Ni, Mo, and Ta and found that the transition from low sputtering pressures to higher working gas pressures occurs at threshold pressures that increase with the atomic mass of the coating material.

Controlling Radiation Damage

Graeme J. Ackland
- 26 Mar 2010 - 
TL;DR: A mechanism in copper is described that suggests that nanomaterials in general might have exceptional radiation resistance, and is supported by some previous experimental findings and suggests new directions for trial materials.

TL;DR: Amorphous binary M(= Mo, Ta or W)-Si and ternary MSi-N, r.f.-sputtered from M 5 Si 3 and WSi 2 targets, are assessed as diffusion barriers between silicon substrates and copper overlayers in this paper.

Tungsten as first wall material in fusion devices

Michael Kaufmann, +1 more
TL;DR: In this paper, the authors describe the status of investigations on the use of tungsten as a first wall material in a fusion reactor. But, due to the high erosion rate of tritium, carbon plasma facing components (PFCs) appear to be unacceptable for a commercial fusion reactor, therefore, they are not suitable for the first wall coverage.
