A new method for identification and characterization of an acyl phosphate linkage in phosphorylated proteins is presented. The method involves reductive cleavage of the acyl phosphate bond with sodium [3H]borohydride to form a labeled aminohydroxy acid residue. [3H]Borohydride reduction of the phosphorylated (Ca2+, Mg2+)-adenosine triphosphatase of sarcoplasmic reticulum, followed by analysis o...

surface oxidized carbon vulcane xc-72 is prepared as catalyst support and platinumnanoparticles are chemically anchored onto the modified surface. the nanoparticles of pt weresynthesized by reduction of h2ptcl6 with sodium borohydride in a 5.5 m buffer solution ofsodium citrate; the complexation of citrate with metal ions is beneficial to the formation ofnanoparticles. the electro-oxidation of ...

The rearrangement reaction of thebaine (1) with methanesulfonic acid, in the presence of hydrogen sulfide, resulted in a sulfide-type bisaporphine 13, instead of the expected thiol 12. The acidic hydrolysis of the thiocyanato derivatives 3, 9, 20 and 21, obtained from thebaine (1), as well as the reduction of 9 and 21 with sodium borohydride yielded disulfide-type bisaporphines 16 and 23.

Manganese oxides are often used as catalysts for oxygen reduction reactions due to their low price and high stability, they have been extensively studied. However, the poor electrical conductivity intrinsic activity of manganese restrict its application in reduction. In this paper, oxide octahedral molecular sieve is research object, performance material adjusted by surface etching treatment so...

This work is aimed at preparation of small silver nanoparticles (Ag NPs) with various sizes using two-step preparation method. The silver bromide nanoparticles were prepared in the first step and they were reduced to metal silver nanoparticles in the second step. Size of prepared silver nanoparticles was controlled by using of several modifiers. Two surfactants (SDS and Tween 80) and two natura...

A class of novel nickel cobalt oxide hollow nanosponges were synthesized through a sodium borohydride reduction strategy. Due to their porous and hollow nanostructures, and synergetic effects between their components, the optimized nickel cobalt oxide nanosponges exhibited excellent catalytic activity towards oxygen evolution reaction.
