Oxidation on Metal Oxide Surfaces

1968
The 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, 1973
Abstract 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 ...

Polyneuropathy Due to Ethylene Oxide, Propylene Oxide, and Butylene Oxide

Environmental Research, 1993
Axonal 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.

Oxides, Oxides, and More Oxides: High-κ Oxides, Ferroelectrics, Ferromagnetics, and Multiferroics

Critical Reviews in Solid State and Materials Sciences, 2009
We review and critique the recent developments on multifunctional oxide materials, which are gaining a good deal of interest. Recongnizing that this is a vast area, the focus of this treatment is mainly on high-κ dielectric, ferroelectric, magnetic, and multiferroic materials.

Oxidants, oxidative stress and the biology of ageing

Nature, 2000
Living in an oxygenated environment has required the evolution of effective cellular strategies to detect and detoxify metabolites of molecular oxygen known as reactive oxygen species. Here we review evidence that the appropriate and inappropriate production of oxidants, together with the ability of organisms to respond to oxidative stress, is ...

Cobalt oxide and antimony oxide effects in the zinc oxide-bismuth oxide system

Materials Research Bulletin, 1994
The effects of Co[sub 3]O[sub 4] and Sb[sub 2]O[sub 3] in the ZnO-Bi[sub 2]O[sub 3] sintering process have been studied by several researchers. However, some aspects of their influence on ZnO-Bi[sub 2]O[sub 3] sintering behavior, which are important for the characteristics of ZnO varistors, such as the phase distribution, are still not well understood.

Modelling oxide–oxide and oxide–metal interfaces

J. Chem. Soc., Faraday Trans., 1990
Recent 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 ...

Silicon Oxides and Oxidation

1993
Silicon dioxide has many desirable properties: an optical material of wide band gap known by many as the stable insulating oxide which helps silicon retain its supremacy in microelectronic devices. I shall discuss some of the recent studies increasing our understanding in three main areas: oxidation processes; interface issues; and processing and its ...
