Oxide Interfaces: Theory of Oxide-Oxide and Oxide-Metal Interfaces
1987We discuss the prediction of oxide-metal adhesion emphasising those cases where the metal does not react chemically with the oxide. Theoretically, the complications are forbidding, partly because of the chemical and morphological complexity of practical systems, and partly because there are many distinct contributions to adhesion.

Oxidant signals and oxidative stress
Current Opinion in Cell Biology, 2003Although oxidants clearly possess the capacity to behave in a random and destructive fashion, growing evidence suggests that in many instances the production of reactive oxygen species is tightly regulated and their downstream targets exquisitely specific.

Role of Nitric Oxide in Hydroxylamine Oxidation by Ammonia-Oxidizing Bacteria
Applied and Environmental Microbiology, 2023Ammonia oxidation by chemolithoautotrophic ammonia-oxidizing bacteria (AOB) is thought to contribute significantly to global nitrous oxide (N 2 O) emissions and leaching of oxidized nitrogen, particularly through their activity in nitrogen (N)-fertilized agricultural production systems.

Oxidation on Metal Oxide Surfaces
1968The redn. of transition metal oxides and of SnO2 + Sb2O3 by 1-butene and butadiene was investigated. A single parameter Qo, defined as the heat necessary to dissociate 0.5 O2 from the oxide, detd. the type of reaction. Starting from Q0 = 17 (MnO2) and proceeding to Q0 = 70 (SnO2), the redn. produces; CO2 -> (oxygenated products) -> butadiene ->

The decomposition of nitrous oxide on neodymium oxide, dysprosium oxide and erbium oxide
Journal of Catalysis, 1973Abstract The decomposition of nitrous oxide on neodymium oxide, dysprosium oxide and erbium oxide has been studied in two pressure ranges of approximately 1 to 10 Torr and 10 to 100 Torr, over a temperature range of 400 to 600 °C. In all cases, the kinetics are first-order in nitrous oxide with a pseudo-rate constant varying with initial pressure ...

Modelling oxide–oxide and oxide–metal interfaces
J. Chem. Soc., Faraday Trans., 1990Recent years have seen a large increase in interest in interfaces of ionic and ceramic crystals and an appreciation of their importance in determining many of the properties of materials. Static-lattice calculations have made a major impact on the interpretation of the role of point defects in controlling observed behaviour in the bulk and are now ...

Polyneuropathy Due to Ethylene Oxide, Propylene Oxide, and Butylene Oxide
Environmental Research, 1993Axonal neuropathy occurs due to occupational ethylene oxide (EtO) exposure. The experimental model of human EtO neuropathy was established. In addition, the neurotoxic effects of propylene oxide (PpO) and butylene oxide (BtO) were demonstrated in rats.

Kinetics of the Oxidation of Triphenylphosphine by Nitric Oxide
Inorganic Chemistry, 2002The oxidation of PPh3 by NO to N2O and Ph3PO in homogeneous solution occurs by third-order kinetics, d[Ph3P]/dt = k3[Ph3P][NO]2; analysis of solvent and substituent effects suggests formation of a phosphonium diazeniumdiolate intermediate prior to oxygen transfer from nitrogen to phosphorus.
