TL;DR: In this article, a Ni (110) surface reconstruction under the influence of adsorbed hydrogen atoms can proceed in two different ways: below 180 K, a 2×1 lattice-gas structure with θ H = 1.0 transforms cooperatively into a two-dimensional 1×2 structure by additional uptake of hydrogen up to 1.5, and activation local transformation into a more stable one-dimensional structure starts already at low coverages.

TL;DR: In this paper, an Al(111) surface in h.c.p-type threefold hollow sites is shown to exhibit local variations of their electronic structure induced by the chemical bond to the adsorbate, which lead to a decrease of the tunnel current at nearest neighbours and an increase at next-nearest neighbours.

TL;DR: A beam of silver clusters of 3 nm average diameter is produced by the gas-aggregation technique and deposited onto the NaCl (100) surface, which leads in part to the growth of rodlike particles with the structure of truncated decahedra of typical dimensions 70 nm long and 10 nm diameter and a fivefold symmetry.

TL;DR: In this article, the authors used scanning tunneling microscopy at 60\char21{}100 K to investigate the thermal motions and interactions of oxygen molecules chemisorbed on a Ag(110) surface.

TL;DR: It can be shown that H on Pd(111) and O on Cu(110) adsorb at 300 K above the first metal layer, in contrast to earlier conclusions which favored subsurface sites.
