nanomagnetic mgfe2o4 is an active, stable, and reusable catalyst for the oxidation of alcohols. the oxidation of various primary and secondary alcohols has been examined and related corresponding products were obtained in good yields. the reactions were carried out in the presence of water as solvent and oxone (at room temperature) or h2o2 (at 60 ºc) as an oxidant. the catalyst was investigated...

ABSTRACT: Degumming and neutralization processes are two essential stages carried out on crude edible oils in order to remove some unwanted impurities namely gums and free fatty acids. In this research study two popular less expensive commercial oils that are consumed to a great extent namely soyabean and sunflower seed oils are selected and subjected to both degumming and neutralization proces...

The regulation of nonenzymatic and enzymatic lipid oxidation reactions by nitric oxide (.NO) is potent and pervasive and reveals novel non-cGMP-dependent reactivities for this free radical inflammatory and signal transduction mediator.NO and its metabolites stimulate and inhibit lipid peroxidation reactions, modulate enzymatically catalyzed lipid oxidation, complex with lipid-reactive metals, a...

The combination of visible light, photovoltaics, and electrochemistry provides a convenient, inexpensive platform for conducting a wide variety of sustainable oxidation reactions. The approach presented in this article is compatible with both direct and indirect oxidation reactions, avoids the need for a stoichiometric oxidant, and leads to hydrogen gas as the only byproduct from the correspond...

A combination of photocatalytic oxidation experiments and quantum mechanical calculations was used in order to describe the mechanism and the nature of the photocatalytic oxidation reactions of dinitronaphthalane isomers and interprete their reactivities within the framework of the Density Functional Theory (DFT). The photocatalytic oxidation reactions of three dinitronaphthalene isomers, 1,3-d...

a mixture of manganese, cobalt and lead para-amino benzoates supported on silica gel is used to catalyze oxidation of xylenes to toluic acids in presence of oxygen or air. reactions are clean and catalysts can be recovered easily and reused.

Ferric leghemoglobin reductase (FLbR) from soybean (Glycine max [L.] Merr) nodules catalyzed oxidation of NADH, reduction of ferric leghemoglobin (Lb(+3)), and reduction of dichloroindophenol (diaphorase activity). None of these reactions was detectable when O(2) was removed from the reaction system, but all were restored upon readdition of O(2). In the absence of exogenous electron carriers an...

The anaerobic oxidation of Fe(II) by subsurface microorganisms is an important part of biogeochemical cycling in the environment, but the biochemical mechanisms used to couple iron oxidation to nitrate respiration are not well understood. Based on our own work and the evidence available in the literature, we propose a mechanistic model for anaerobic nitrate-dependent iron oxidation. We suggest ...
