TLDR
In this paper, the details of the interface region of a molecular beam epitaxially grown Al single crystal on a single-crystal substrate were studied using X-ray diffraction and total external reflection.Abstract:
A new technique utilizing conventional x‐ray diffraction in conjunction with total external reflection has provided a powerful tool for studying ordered interfaces and surface phenomena. It has been used in this work to study the details of the interface region of a molecular beam epitaxially grown Al single crystal on a molecular beam epitaxially grown GaAs single‐crystal substrate. A simple model including variations of the lattice parameter and disorder in the interface region is in agreement with these experimental results.read more

Smaller is faster and more sensitive: the effect of wire size on the detection of hydrogen by single palladium nanowires.
TL;DR: It is concluded that the kinetics of hydrogen adsorption limits the observed response rate seen for the nanowire, and that hydrogen desorption from thenanowire limits the observation recovery rate; proton diffusion within PdHx does not limit the rates of either of these processes.

CXVII. The total reflexion of X-rays
TL;DR: In this article, the total reflexion of X-rays was studied and it was shown that X-ray can be interpreted as a measure of the amount of radiation absorbed by the human body.
