Catalytic behavior of rare earth oxides in the oxidation of nitrogen oxide

Journal of Catalysis, 1977
The catalytic activity of the series of nonsupported rare earth oxides in the oxidation of NO and the temperature-programmed desorption spectra of the O/sub 2/--Pr/sub 6/O/sub 11/, which gave the highest activity in the reaction, were reported. An attempt was made to clarify the role of oxygen from the oxide in the oxidation of NO.

The Mechanical Behaviors in Oxides: Beyond Brittleness

Advanced Materials
ABSTRACT Oxide materials are traditionally perceived as intrinsically brittle due to their strong covalent and ionic bonds, which hinder plastic deformation and limit their applicability in emerging technologies such as flexible and wearable electronics.

[The oxidation behavior of dithranol].

Arzneimittel-Forschung, 1985
When Dithranol is oxidized in a weakly alkaline buffer by air oxygen one has to discuss two different oxidative pathways. Under homogeneous conditions (dithranol dissolved) the only oxidation product is dithranol-dimer (and subsequently dithranol-brown) whereas under heterogeneous conditions (dithranol suspended) mainly chrysazine (dantron) is produced,

Oxidation Behavior of Silicon Carbide

Journal of the American Ceramic Society, 1958
The oxidation of purified green silicon carbide in controlled atmospheres was studied by weight‐gain measurement and by observation of the surface reaction products, including optical measurement of the thickness of the oxide surface film.

Oxidation behavior of aluminum nitride

Journal of Materials Research, 1993
The evaluation of the thermal stability of three different fully dense AlN materials in the temperature range of 600 °C to 1400 °C in air indicates the strong effect of the starting composition on the oxidation process. The oxidation resistance of pure AlN and Y2O3-doped AlN was found to be good up to ≍1350 °C. The kinetics are linear (1100 ≤ T ≤ 1400 °

The Ion Exchange Behavior of Oxides

2016
Oxides comprise the most common ion-exchange materials on our planet, with the clay minerals alone, formed by the weathering of rock, having a total mass of around 1025 g. This mass represents almost one-third of the total mass of Earth’s crust and is more than six times the mass of Earth’s oceans. These fine-grained ion exchange materials play a major

Thermoelectric Behavior of Nickel Oxide

The Journal of Chemical Physics, 1955
Measurements have been made on the thermoelectric power of several nickel oxide samples containing foreign ions. Using an energy model recently proposed for nickel oxide, the effect of the nature and concentration of additions on the Fermi level, hole concentration, and mobility is derived and discussed.

Oxidation Behavior of Uranium Monophosphide

Journal of the American Ceramic Society, 1965
Oxidation of UP at moderate temperatures was studied using DTA, X‐ray diffraction, TGA, and chemical analysis. Heating rates, atmosphere, and particle size were varied. Oxidation behavior of UP was significantly different from that of UC, UN, US, and UAs, all of which possess the NaCl‐type crystal structure.
