Trends in Stability of Perovskite Oxides

Angewandte Chemie International Edition, 2010
Perovskite oxides with general formula AMO3 have a large variety of applications as dielectrics and piezoelectrics, ferroelectrics and/or ferromagnetic materials, among others. Rare earth and alkaline earth metal perovskites are useful as catalysts for hydrogen generation, as oxidation catalysts for hydrocarbons, and as effective and inexpensive ...

Stability of Procaine in Deuterium Oxide

Journal of Pharmaceutical Sciences, 1964
Stability of procaine in protium oxide and deuterium oxide was studied over the pH and "apparent" pH range 8 to 11. Studies were conducted at 40 and 100°.

Stabilization of Silicon–Carbon Mixed Oxides

Journal of the American Chemical Society, 2015
The first carbene-stabilized silicon-carbon mixed oxide, (SiO2)2CO2 (4), was synthesized by CO2 oxidation of either carbene-stabilized disilicon, L:Si═Si:L (L: = :C{N(2,6-Pr(i)2C6H3)CH}2) (1), or carbene-stabilized Si2O3 (2) (which can be obtained via N2O oxidation of 1).

Oxidative Stability of Conjugated Linolenic Acids

Journal of Agricultural and Food Chemistry, 2009
Interest in conjugated linolenic acid (CLnA) and conjugated linoleic acid (CLA) as functional lipids is growing. The present study was (i) to study the oxidative stability of individual CLnA isomers and (ii) to compare the oxidative stabilities of CLnA and CLA with their corresponding nonconjugated counterparts, α-linolenic acid (LN) and linoleic acid (

Carbene‐Stabilized Phosphenium Oxides and Sulfides

Chemistry – A European Journal, 2012
AbstractCarbene→chalcogenophosphenium adducts, which correspond to an intermolecular stabilization mode of the so far elusive, free oxo‐ and thiooxophosphenium species [R2P+=X] (X=O, S) by imidazolylidene (NHC) and diaminocyclopropenylidene (BAC) donors, have been isolated and fully characterized.

Stabilizing nanocrystalline grains in ceramic-oxides

Physical Chemistry Chemical Physics, 2013
Nanocrystalline ceramic-oxides are prone to grain growth rendering their highly attractive properties practically unusable. Using atomistic simulations of ceria as a model material system, we elucidate a framework to design dopant-pinned grain boundaries that prevent this grain growth.

Stabilization of Tubulin by Deuterium Oxide

Biochemistry, 1999
Tubulin is an unstable protein when stored in solution and loses its ability to form microtubules rapidly. We have found that D2O stabilizes the protein against inactivation at both 4 and 37 degrees C. In H2O-based buffer, tubulin was completely inactivated after 40 h at 4 degrees C, but in buffer prepared in D2O, no activity was lost after 54 h ...

Oxidative Stability of Tree Nut Oils

Journal of Agricultural and Food Chemistry, 2008
The oxidative stability of selected tree nut oils was examined. The oils of almond, Brazil nut, hazelnut, pecan, pine nut, pistachio, and walnut were extracted using two solvent extraction systems, namely, hexane and chloroform/methanol. The chloroform/methanol system afforded a higher oil yield for each tree nut type examined (pine nut had the highest

Graphene Oxide’s Surprising Stability

Chemical & Engineering News Archive, 2015
The stability of graphene oxide films in water is crucial to their use as membranes for aqueous filtration and separation applications. That stability is also something of a mystery.

Stabilization of Pharmaceuticals to Oxidative Degradation

Pharmaceutical Development and Technology, 2002
A guide for stabilization of pharmaceuticals to oxidation is presented. Literature is presented with an attempt to be a ready source for data and recommendations for formulators. Liquid and solid dosage forms are discussed with options including formulation changes, additives, and packaging documented. In particular, selection of and methods for use of
