We studied the OH oxidation of submicron aerosol particles consisting of pure palmitic acid (PA) or thin (near monolayer) coatings of PA on aqueous and effloresced inorganic salt particles. Experiments were performed as a function of particle size and OH exposure using a continuousflow photochemical reaction chamber coupled to a chemical ionization mass spectrometer (CIMS) system, for detection...

A comprehensive survey of the interaction of the copper proteins and oxygen is presented including a correlation of structure, function, and other properties of the known copper oxidases and of hemocyanin. The origin of their blue color and the structure of copper complexes and copper proteins are related to the oxidation state of copper ion and relevant electronic transitions probably arising ...

Inspired by the paper, 'Brain glutamine synthesis requires neuronal-born aspartate as amino donor for glial glutamate formation' by Pardo et al, a modified model of oxidation-reduction, transamination, and mitochondrial carrier reactions involved in aspartate-dependent astrocytic glutamine synthesis and oxidation is proposed. The alternative model retains the need for cytosolic aspartate for tr...

The effect of pretreatment conditions on the oxidation state and activity of micelle-synthesized Pt nanoparticles supported on ZrO2 was studied for methanol decomposition and oxidation reactions. An O2-pretreatment is observed to be effective for producing clean, stable, and active nanoparticles. Pt-oxide species formed during such pretreatments were found to have little influence in methanol d...

A model of the self-discharge process of a nickel-hydrogen cell is presented. The model includes three electrochemical reactions on the nickel electrode (reduction of nickel oxyhydroxide, oxidation of hydrogen, and oxidation of hydroxyl ion to form oxygen) and two electrochemical reactions on the hydrogen electrode (reduction of oxygen and oxidation of hydrogen). The self-discharge pressure pro...

To understand the charge transport ability of the metal coordinated cyclobutadiene, a series of cyclobutadiene cobalt cyclopentadiene (CbCoCp) omplexes containing electrochemically polymerizable thiophene units were synthesized. The complexes were electrochemically polymerized nd the resulting polymers were characterized by cyclic voltammetry, in situ conductivity and UV–vis spectroelectrochemi...

Oxidation of binuclear Pd(II) complexes with PhICl(2) or PhI(OAc)(2) has previously been shown to afford binuclear Pd(III) complexes featuring a Pd-Pd bond. In contrast, oxidation of binuclear Pd(II) complexes with electrophilic trifluoromethylating ("CF(3)(+)") reagents has been reported to afford mononuclear Pd(IV) complexes. Herein, we report experimental and computational studies of the oxi...
