Carbene‐Stabilized Phosphenium Oxides and Sulfides
Chemistry – A European Journal, 2012AbstractCarbene→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, 2013Nanocrystalline 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, 1999Tubulin 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, 2008The 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, 2015The 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, 2002A 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

Preparation and stability of oxidized polyamines
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1971Abstract The products arising from the oxidation of spermidine and spermine by serum amine oxidase have been purified by ion-exchange chromatography on columns of SE-Sephadex. Oxidized spermidine, dioxidized spermine, and mono-oxidized spermine prepared by this procedure were approx.

Stabilization Against Thermal Oxidation
1984The autoxidation of hydrocarbons is probably the most extensively studied of all chemical reactions. This statement has been attributed to Bateman1) whose pioneering research at the British Rubber Producer’s Association between 1954 and 1964 established the mechanism for the low-temperature oxidation (autoxidation) of low-molecular weight hydrocarbons ...
