TL;DR: In this paper, the authors used in situ transmission electron microscopy to show that nanometer-sized loops with a Burgers vector of (1/2)111 in alpha-Fe can undergo one-dimensional diffusion even in the absence of stresses that are effective in driving the loops.

TL;DR: In this article, high temperature annealing of pure tungsten irradiated by self-ions was conducted to elucidate microstructural and defect evolution in temperature ranges relevant to fusion reactor applications.

TL;DR: In this paper, a stacking-fault tetrahedra model was proposed to describe how a high concentration of point defects is produced by a large number of parallel shifts of atomic planes without dislocations.

TL;DR: A new type of changing process in the Burgers vector of dislocations is reported by in situ transmission electron microscopy, where small interstitial-type perfect dislocation loops in bcc iron with diameters less than approximately 50 nm are transformed from a 1/2<111> loop to another 1/ 2 <111> one or an energetically unfavorable <100> one.

TL;DR: The Thorium Molten Salt Nuclear Energy Synergetic System [THORIMS-NES] as mentioned in this paper is a symbiotic system, based on the thorium-uranium-233 cycle.
