Ion and electron irradiation-induced effects in nanostructured materials
TL;DR: In this article, the authors review recent progress in the understanding of effects of irradiation on various zero-dimensional and one-dimensional nanoscale systems, such as semiconductor and metal nanoclusters and nanowires, nanotubes, and fullerenes.

Hydrogen in tungsten: Absorption, diffusion, vacancy trapping, and decohesion
TL;DR: In this article, the authors report results from periodic density-functional theory calculations for three crucial aspects of this interaction: surface-to-subsurface diffusion of H into W, trapping of H at vacancies, and Henhanced decohesion, with a view to assess the likely extent of hydrogen isotope incorporation into tungsten reactor walls.
Journal ArticleDOI
Ion-driven deuterium retention in tungsten
TL;DR: In this paper, the ion-driven retention of deuterium in polycrystalline tungsten (PCW) is studied experimentally and theoretically as a function of temperature, incident ion energy, and ion fluence.

Hydrogen in tungsten as plasma-facing material
J. Roth,Klaus Schmid +1 more
TL;DR: In this article, experimental evidence for the influence different trapping sites have on the hydrogen inventory in W as studied in ion beam experiments and low-temperature plasmas is presented. And the contribution of different traps to the tritium inventory in future fusion reactors is estimated.

A review of modelling and simulation of hydrogen behaviour in tungsten at different scales
TL;DR: In this article, the authors reviewed the recent findings regarding the behavior of H isotopes in W obtained via modelling and simulation at different scales, including dissolution, diffusion, accumulation and bubble formation.

The diffusion and trapping of hydrogen in steel
TL;DR: In this paper, the mobility of dissolved hydrogen in an iron lattice having a population of extraordinary, or trapping, sites for hydrogen is analyzed under the assumption of local equilibrium between the mobile and the trapped populations.

Thermal analysis of trapped hydrogen in pure iron
W. Y. Choo,Jai Young Lee +1 more
TL;DR: The relative amount of trapped hydrogen and the activation energy for its evolution from various lattice defects in iron were calculated by monitoring the pressure change caused by release of hydrogen from charged specimens heated at uniform heating rates as discussed by the authors.

The role of vacancies and dislocations in the nucleation and growth of gas bubbles in irradiated fissile material
TL;DR: In this paper, it was shown that fine scale bubbles are to be expected in reasonably pure material, the bubbles nucleating either homogeneously with a spacing less than a micron or on any nucleation sites that may exist on this or a finer scale.
Journal ArticleDOI
Self-trapping of helium in metals
TL;DR: In this paper, it was shown that helium atoms in a metal lattice are able to cluster with each other, producing vacancies and nearby self-interstitial defects, and that the binding energy of each additional helium atom to these clusters increases with helium concentration.

Ion-beam studies of hydrogen-metal interactions
TL;DR: Theoretical studies coupled with ion implantation and ion-beam analysis have provided a large body of new quantitative information on hydrogen interactions within metal matrices and at metal surfaces as discussed by the authors.
