Abstract: A method of controlling oxygen vacancy concentration in a semiconducting metal oxide includes exposing a treated surface of a crystalline metal oxide to water at a temperature and pressure sufficient to maintain the water in a liquid phase. During the exposure, a portion of the water is adsorbed onto the treated surface and dissociates into atomic oxygen and hydrogen. The atomic oxygen is injected into and diffuses through the crystalline metal oxide, forming isolated oxygen interstitials and oxygen defect complexes. The isolated oxygen interstitials replace oxygen vacancies in the crystalline metal oxide.

Abstract: Provided herein is a process for the pretreatment of workpieces having a surface of aluminum or aluminum alloys for noncutting forming and/or joining by welding or adhesive bonding to similarly pretreated, precoated workpieces, or to optionally precoated parts. The parts are composed of steel, galvanized steel, and/or alloy-galvanized steel. Further provided herein is a subsequent permanent corrosion-protecting treatment by phosphating, by means of a chromium-free conversion treatment, by application of primer, or by surface coating, where the workpieces are a) pickled by means of an aqueous, acidic solution comprising mineral acid by dipping or spraying, b) rinsed with water, and c) brought into contact with an aqueous, acidic, chromium-free solution including Zr as complex fluoride and Mo as molybdate by application by dipping or spraying. After subsequent drying, a layer weight from 2 to 15 mg/m2 of Zr and Mo is formed.

Abstract: Methods for selective deposition of silicon oxide films on dielectric surfaces relative to metal surfaces are provided. A metal surface of a substrate may be selectively passivated relative to the dielectric surface, such as with a polyimide layer or thiol SAM. Silicon oxide is selectively deposited on the dielectric surface relative to the passivated metal surface by contacting the dielectric surface with a metal catalyst and a silicon precursor comprising a silanol.
