Defects on surfaces
TLDR
A brief review of various types of defects on surfaces and their role in surface reactions is presented in this article, with particular emphasis on defects like steps/kinks and additives (promoters and poison).Abstract:

The hydration of periclase: atomistic insights from quantum-chemical look
TL;DR: In this paper, a density functional theory study has been carried out to investigate the hydration kinetics of periclase (MgO) through the interaction between water and pericloase (0, 0, 1) and (1, 1, 1), 1) surfaces.

Interaction of ammonia with Fe(111) and Fe(100) surfaces
TL;DR: The adsorption and decomposition of NH 3 on clean and nitrogen covered Fe(111) and Fe(100) surfaces has been studied by means of UPS, AES, LEED, thermal desorption, and work function measurements as mentioned in this paper.

Relation between surface relaxation and surface force constants in clean and oxygen-covered Ni (001)
TL;DR: In this article, the first interlayer spacing of Ni(001) is contracted if the surface is clean, but expanded if it is covered by half a monolayer of oxygen.

Truncation-induced multilayer relaxation of the A1(110) surface
J. R. Noonan,H. L. Davis +1 more
TL;DR: In this article, the results from a low-energy electron diffraction (LEED) analysis of the Al(110) surface are presented and discussed, showing that a multilayer relaxation exists in the Al110 surface region such that the spacing between layers 1 and 2 has a relative change of -8.5% from the bulk value.
