An improved procedure for determination of composition of heteropolysaccharides by radiochromatography of sodium [3H]borohydride-reduced hydrolyzates has been developed. The method is accurate and sensitive, is less cumbersome and more reliable than similar procedures currently in use, and permits, for the first time, compositional analysis of hydrolyzates containing both hexoses and uronic aci...

Rare-earth metal tris(borohydrides) [Ln(BH4)3(thf)3] (Ln = Y, La, Nd, Sm) are converted with one equivalent of the Brønsted acid [NEt3H]+[BPh4]- in thf into the monocationic bis(borohydride) complexes [Ln(BH4)2(thf)5]+[BPh4]-. They efficiently initiate the ring-opening polymerisation of epsilon-caprolactone.

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.

The title compound, C(22)H(22)BNO(3), was unintentionally obtained from salicyl-aldehyde benzyl-amine and sodium borohydride. The B-O bond lengths lie in the range 1.425 (2)-1.463 (2) Å, and B-N = 1.641 (2) Å. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains in the [010] direction.

Beyond hydrogen storage: The first example of reversible magnesium deposition/stripping onto/from an inorganic salt was seen for a magnesium borohydride electrolyte. High coulombic efficiency of up to 94 % was achieved in dimethoxyethane solvent. This Mg(BH(4))(2) electrolyte was utilized in a rechargeable magnesium battery.

This unit describes the fractionation and analysis of neutral oligosaccharides by high-performance liquid chromatography (HPLC) on bonded amine columns. Separation is based upon hydrogen bonding between the NH2 groups of the column and the hydroxyl groups of the oligosaccharides. A support protocol describes the reduction and desalting of neutral oligosaccharides with sodium borohydride.

In this study, we investigated the synthesis of nano-size iron particle using a borohydride reduction of ferric ion in the presence of solvent containing carbonyl groups. When we varied the contents of solvent, there is a corresponding variation of synthesis and iron form. Each sample of synthesized iron particles was characterized by transmission electron microscope (TEM) and powder X-ray diff...

The inherent property of palladium to form hydride is effectively exploited for the removal of adsorbed stabilizer and capping agents. Formation of hydride on exposure of Pd nanoparticles to sodium-borohydride weakens the metal's interaction with the adsorbed-impurities and thus enables their easy removal without compromising the shape, size and dispersion.
