Doped and undoped ZnS semiconductor nanocrystals having different recombination pathways are explored to study the charge transfer reaction between the nanocrystals and the 4-nitrophenol/sodium borohydride redox couple.

The ‘living’ species selenide anion Se2, generated in situ by the reduction of 1,2-bis(bis(4-chlorophenyl)methyl)diselane with sodium borohydride, was treated with various organic halides to afford synthetically important organoselenium compounds including α,ω-diselenoethers and selenides bearing ester functionality, under mild and neutral conditions. These compounds have been characterized ana...

An analytical method for dimethyl sulfoxide (DMSO) in aqueous samples at nanomolar levels has been improved. DMSO was reduced to dimethyl sulfide (DMS), concentrated on an adsorbent, and measured by gas chromatography. In the presence of iron chloride, the sodium borohydride (NaBH4) reduction of DMSO proceeded smoothly and efficiently, and the repeatability of this reaction was significantly im...

Abstract Synthesis of silver nanoparticles was successfully synthesized by a chemical reduction method using nitrate (AgNO 3 ) as precursor and sodium borohydride (NaBH 4 reducing agent. The optical properties were studied based on their surface plasmon resonance (SPR) phenomenon UV-Visible spectrophotometry. absorbance spectra colloidal show the peak at wavelength range 380 nm to 450 nm.
