TL;DR: In this paper, the hP18 variant of the P6 3 /mcm structure was determined using transmission electron microscopy and X-ray diffraction techniques, and the results of the evolution and stability of this structure were presented and discussed.

TL;DR: In this paper, the use of TEM in the study of various types of nanomaterials is described in the context of high-resolution electron microscopy (HREM), which can provide morphological information, crystallographic details and chemical composition of phases distributed on a very fine scale in a given microstructure.

TL;DR: DFT and classical molecular dynamics simulations suggest a hopping model in which the oxygen ions migrate from one tetrahedral site to another via octahedral interstitial sites, and nudged elastic band calculated diffusion barriers indicate that 〈001〉 is the easy direction for anion migration in the normal and superionic states.

TL;DR: In this article, the cross-section of Alloy 800 substrates indicated formation of multilayer of aluminides as revealed by microscopy, electron probe microanalysis and X-ray diffraction.

TL;DR: In this paper, an Electron Beam (EB) welding technique, which can produce narrow deep penetration welds with nominal heat affected zone (HAZ) and minimum contamination, is used to weld the Nb-1Zr-0.1C alloy.
