TL;DR: Using a combination of quantitative low-energy electron diffraction, scanning tunneling microscopy, and density functional theory calculations, it is shown that an ordered array of subsurface iron vacancies and interstitials underlies the well-known (2×2)R45° reconstruction of Fe3O4(001).

TL;DR: TiO2 selectively adsorbs atmospheric carboxylic acids that are typically present in parts-per-billion concentrations while effectively repelling other adsorbates, such as alcohols, that are present in much higher concentrations.

TL;DR: A combination of photoemission, atomic force, and scanning tunneling microscopy/spectroscopy measurements shows that excess electrons in the TiO2 anatase (101) surface are trapped at step edges, and steps act as preferred adsorption sites for O2.

TL;DR: It is shown that carbon monoxide plays a dual role in the coarsening of otherwise highly stable Pt atoms on an Fe3O4(001) support: CO adsorption weakens the adatom–support interaction inducing mobility, and stabilizes the Pt dimer against decay into two adatoms.

TL;DR: In this paper, the adsorption of Ni, Co, Mn, Ti, and Zr at the (root 2 x root 2)R45 degrees-reconstructed Fe3O4(001) surface was studied by scanning tunneling microscopy, x-ray and ultraviolet photoelectron spectroscopy, low-energy electron diffraction (LEED), and density functional theory (DFT).
