  • The interaction between perovskite oxides and water can have a significant influence on practical performance. Here the authors study the dynamics of surface water adsorption and hydroxide formation during monolayer formation on a ruthenate.

  • Surface structures can have an important effect on the traits of two-dimensional electron liquids. Here, the authors demonstrate how the surface terminations of SrTiO3(001) affect the mechanism and properties of the two-dimensional electron liquid.

  • Photocatalysts such as titanium dioxide that use sunlight to split water and produce hydrogen would be a clean and sustainable solution to many problems, but their efficiency is currently too low to be widely used. Two approaches to engineer the surface properties of titanium dioxide offer hope that its efficiency can be increased.

  • The interaction of water with metal oxides is important for catalysis and biochemistry. Charge rearrangement at the water–anastase (101) interface affects the adsorption of further water molecules, and results in short-range repulsive interactions and locally ordered water-molecule superstructures.

  • Non-contact atomic force microscopy measurements are used to probe the hydrogen bond strength of individual surface hydroxyl groups and determine their acidity with atomic precision.

  • The availability of surface oxygen vacancies or electrons is often viewed as the defining factor for the reactivity of perovskite oxides. Two precisely controlled surfaces on SrTiO3(110) show strikingly different O exchange kinetics, which the authors ascribe to the flexibility of the surface polyhedra.

  • Although the coarsening of catalytically active metal clusters can be accelerated by the presence of gases, the role played by gas molecules is difficult to ascertain. Carbon monoxide-induced coalescence of Pd adatoms supported on a Fe3O4 surface is now investigated at room temperature, and Pd-carbonyl species are shown to be responsible for their mobility.

  • Mica is a naturally occurring 2D mineral that has been heavily studied in many diverse areas. Here authors present atomic force microscopy images to study the mica surface in ultra-high vacuum conditions; they unveil the distribution of its surface K+ ions and give insights into the distribution of subsurface Al3+ ions.

  • As ternary perovskite-type oxides are increasingly used in fuel cells and catalysis, greater understanding of their surface chemical properties is required. Here the authors report a pronounced ordering of hydroxyls on the cleaved (001) surface of Ca3Ru2O7 perovskite induced by O-octahedral rotation and tilt.

  • Defect-free surfaces with excess charge are typically described as a homogeneous 2D electron gas. Here, in contrast, the authors find that the KTaO3(001) surface hosts a charge density wave coexisting with a pattern of electron polarons, highly localized states of excess electrons bound to a lattice distortion.

  • Knowing how individual water molecules interact with surfaces is crucial for understanding surface and interface phenomena. Here, the authors show how local water-water interactions enable an unforeseen and surprisingly rapid mechanism of atom exchange between a common mineral and its surroundings.

  • Polarons — quasiparticles arising from the interaction of electrons with lattice vibrations — strongly influence materials properties. This Review provides a map of the theoretical models and experimental techniques used to study polarons in materials, presenting paradigmatic examples of different types of polarons and polaron-driven phenomena.
