Thiolate-protected gold nanoclusters are explored for catalytic application in the selective oxidation of sulfide to sulfoxide by PhIO. The TiO(2)-supported Au(25)(SR)(18) nanocluster catalysts give rise to high catalytic activity (e.g.∼97% conv. of Ph-S-CH(3) and ∼92% selectivity for Ph-S(=O)-CH(3) sulfoxide) and show excellent recyclability in the sulfoxidation process.

Interactions of oxyvanadium compounds with cellular metabolism have recently been demonstrated. Membrane-stimulated vanadate-dependent NADH oxidation has been hypothesized to involve the cellular accumulation of HzOz, which may cause the vanadate sensitivity of animals and microbes. This report shows that the vanadate-dependent NADH oxidation activity of the yeast plasma membrane requires oxyge...

The Cyclic Voltammetric (CV) behavior of Alizarin Red-S (ARS), which is an Anthraquinone dye was examined by utilizing TX-100 modified carbon nanotube paste electrode (TX-100MCNTPE). The surfactant utilized is TX-100, and it has been found that it has good electrocatalytic activity towards ARS. Distinctive parameters like pH, scan rate, detection limit have been studied in the potential range o...

(1, 2). However, it was reported in the foregoing paper (3), that the -S-Slinkages formed by iodine oxidation of the SH-groups of native egg albumin could react with the thiol-form of thiamine or O-benzoylthiamine (OBT) without denaturation. To investigate the effect of denaturation on the reaction is an interesting problem, giving means of elucidating the molecular structure of pro teins. Inve...

The CO oxidation behaviors on single Au atom embedded in two-dimensional h-BN monolayer are investigated on the basis of first-principles calculations, quantum Born-Oppenheim molecular dynamic simulations (BOMD) and micro-kinetic analysis. We show that CO oxidation on h-BN monolayer support single gold atom prefers an unreported tri-molecular Eley-Rideal (E-R) reaction, where O2 molecule is act...
