TLDR
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.About:

Efficient annealing of radiation damage near grain boundaries via interstitial emission.
TL;DR: Simulations show that grain boundaries in copper can act as sinks for radiation-induced defects, and find thatgrain boundaries have a surprising “loading-unloading” effect.

Formation process of tungsten nanostructure by the exposure to helium plasma under fusion relevant plasma conditions
TL;DR: In this paper, it was shown that the tungsten nanostructure is easily formed when the temperature is in the range 1000-2000 K, and the incident ion energy is higher than 20 eV.
