TL;DR: In this article, short duration laser pulses have been used to simulate the deformation defect structure that develops in 304(L) austenitic stainless steel during exposure to sodium-water reaction.

TL;DR: In this paper, the energy of the ions impinging on the substrate during deposition was varied by changing the rf self bias voltage developed on a substrate, and the results obtained from different characterization techniques are correlated and explained on the basis of existing growth models for DLC films.

TL;DR: In this paper, a wurtzite GaN nanoprotruded microbelts with Ga2O3 core, with typical thickness 1-10μm, and length of few millimeters are synthesized by thermal annealing of Ga metal and subsequent reaction with ammonia at a low flow rate.

TL;DR: In this article, a custom made premixed-diffusion type burner with an extra coaxial oxygen inlet close to the burner mouth enabled variation of deposition temperature from 600 to 900°C in steps of 100 (± 10)°C.

TL;DR: In this paper, the influence of nitrogen concentration on the microstructure, chemical and electronic properties of Fe-N thin films and their tribological behavior are studied, and the lowest friction and longest wear life is observed in the film with 12% nitrogen, which is due to the formation of e-Fe2N phase having high bond strength and chemically passive surface.
