We have examined the ion transport properties and the inhibition of rat liver mitochondrial substrate oxidation by the antibiotic W341C. W341C was able to transport 22Na+ and 42K+ across a bulk carbon tetrachloride layer. A preference was shown for K+ transport. With equal molar antibiotic concentrations, W341C transported 42K+ at a greater rate than the K+-selective ionophore nigericin, but tr...

Consider a substitutional solution of two metallic elements A and B. When the alloy is exposed to air at an elevated temperature, A oxidizes, but B does not. In the alloy, the two elements diffuse in opposite directions, but usually at different rates; the nonreciprocal diffusion is known as the Kirkendall effect. At the oxide-alloy interface, metallic atoms may either emit from or inject into ...

A method for efficient and aldehyde-selective Wacker oxidation of aryl-substituted olefins using PdCl(2)(MeCN)(2), 1,4-benzoquinone, and t-BuOH in air is described. Up to a 96% yield of aldehyde can be obtained, and up to 99% selectivity can be achieved with styrene-related substrates.

Cyclohexane oxidation is an important commercial reaction for the preparation of cyclohexanol and cyclohexanone, which are intermediates in the production of adipic acid and caprolactam respectively. These intermediates are important in the manufacture of nylon-6 and nylon-6,6 polymers (Yuan et al 2006 and Shylesh et al 2007). In addition, cyclohexanol and cyclohexanone are also used as solvent...

Tungsten oxidation worked as a simple chemical reaction for the effective detection of 5-hydroxymethylcytosine in DNA, distinguishing it from its epigenetic precursors, 5-methylcytosine and unmethylated cytosine. The tungsten-oxidation product obtained from 5-hydroxymethylcytosine was trihydroxylated thymine and was detected as a cleavage band in gel electrophoresis after treatment with hot pip...

Introduction Apart from the decline of fossil fuel energy resources, there is the added problem, recognised internationally, that fossil fuels are responsible for the greenhouse effect and global warming. Therefore, new alternative ways must be developed to satisfy not only energy needs and the production of chemicals but also for more benign effects on the environment. An approach already bein...

Iron molybdate catalysts were prepared using a sol gel route with malonic acid and oxalic their performance for the selective oxidation of methanol to formaldehyde was evaluated.

Oxidation Catalysts In article number 2211260, Javier Pérez-Ramírez and co-workers report the design of a novel atomically dispersed Mn catalyst on CeO2 for selective oxidation ammonia to nitrous oxide. Effective stabilization low-valence isolated manganese sites results in formation unique catalytic ensemble, which enables facile oxygen activation leads unprecedented activity stability.

A multiwall carbon nanotubes-modified carbon paste electrode (MWCNTs/MCPE) wasfabricated and used to study the electrooxidation of penicillamine (PA) by electrochemicalmethods in the presence of methyldopa (MDOP) as a homogeneous mediator. Theelectrochemical oxidation of PA on the new sensor has been carefully studied. The kineticparameters such as electron transfer coefficient, α, and catalyti...

We report the preparation and characterization of spinel-structured FeCo2O4 nanoparticles for the efficient and selective oxidation of sulfides. The as-prepared FeCo2O4 nanoparticles were characterized by powder X-ray diffraction (PXRD), energy-dispersive X-ray analysis (EDX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). According to TEM images, the size of the...
