Combination of the surfactant-free nonaqueous sol–gel approach with the microwave technique makes it possible to synthesize Fe3O4, CoFe2O4, MnFe2O4, and NiFe2O4 nanoparticles of about 5–6 nm and with high crystallinity and good morphological uniformity. The synthesis involves the reaction of metal acetates or acetylacetonates as precursors with benzyl alcohol at 170 C under microwave irradiatio...

The kinetics of the reaction between malachite green and hidroxide ion was studied in several binary mixtures of water with alcohols (methanol, ethanol, 1-propanol, ethylene glycol and glycerol) and aprotic solvents (DMSO). In all solvents, the selective (preferential) solvation is present. A method for estimating the dielectric constant in the solvation shell and the constant of preferential s...

Greenhouse grown seedlings of corn (Zea mays L.) and foxtail (Setaria faberii Herrm.) were used as source material in determining the intracellular localization of nitrate reductase, nitrite reductase, and glutamic acid dehydrogenase, Nonaqueous and aqueous isolation techniques were used to establish that nitrite reductase is localized within the chloroplasts, but that nitrate reductase and glu...

The electrochemical properties of cytochrome c (cyt c) immobilized on multilayer nanozeolite-modified electrodes have been examined in aqueous and nonaqueous solutions. Layers of Linde type-L zeolites were assembled on indium tin oxide (ITO) glass electrodes followed by the adsorption of cyt c, primarily via electrostatic interactions, onto modified ITO electrodes. The heme protein displayed a ...

As the energy density of state-of-the-art lithium (Li)-ion batteries (LIBs) increases, safety concern LIBs using liquid electrolytes is drawing increasing attention. Flammability a critical link overall performance and Li metal batteries. For this reason, intensive efforts have been devoted to suppressing flammability electrolytes. In short review, common approaches reduce nonaqueous will be su...

A nonaqueous fractionation method to obtain highly purified mesophyll chloroplasts from lyophilized leaves of Zea mays L. is described. The levels of several metabolites including pyruvate were determined in the purified mesophyll chloroplast fractions which were prepared from leaves exposed to different light intensities. The role of pyruvate in the regulation of pyruvate,Pi dikinase in these ...
