Large colloidal environmentally stable silica-coated cobalt particles were synthesized by combining the sodium borohydride reduction in aqueous solution and the Stöber method. Low size polydisperse cobalt spheres with an average size of 95 nm were synthesized by using a borohydride reduction method and were subsequently coated with a thin layer of silica by means of hydrolysis and condensation ...

Sodium borohydride or sodium tetrahydroborate is used as a reducing agent in many organic and inorganic reactions. Therefore, the determination of sodium borohydride present in the system is of great importance. Borohydride releases hydrogen under appropriated conditions in the presence of a suitable catalyst. Since the amount of hydrogen emitted is proportional to the amount of borohydride, th...

A borohydride reduction method was used to identify the phosphorylated amino acid in the phospho-enzyme of the red beet (Beta vulgani L.) plasma membrane ATPase. Plasma membrane fractions were phosphorylated with unlabeled ATP in the presence of MgSO4 at pH 6.5 and then treated with sodium l3Hlborohydride. The borohydride-treated samples were subjected to hydrolysis in 6 normal HCI at 110°C for...

Reduction of reconstituted native type collagen fibrils with sodium borohydride produced a firmly cross-linked polymer as determined by solubility, thermal shrinkage and dissolution, and renaturation studies, and by examination of the denatured protein by ultracentrifugation, gel filtration, polyacrylamide electrophoresis, and carboxymethyl cellulose chromatography. Maximum reduction occurred w...
