Direct borohydride fuel cells (DBFC) oxidize an easily-stored energy-dense (sodium borohydride: NaBH4), that in theory reacts ca. 400 mV below H2 and produces 8 electrons per BH4- anion. However, the oxidation reaction (BOR) does not fully meet these promises practice: electrocatalyst nature, structure state-of-surface, operating conditions (pH, concentration, temperature, fluxes) noticeably in...
Polyaniline and polyamide (nylon 6,6) nanocomposites with Silva were prepared by in-situ oxidativepolymerization of aniline monomers in the presence of Ag salt Nano particles of silver (NPs) were symthesieedby controlled reduction of Ag+ ions kith sodium borohydride at room temperature. Nylon 6,6 wax loaded withAg nanoparfieles by erdrapment of Ag+ ions into the polymer network, followed by red...
The 15e square-planar complexes [Co(PCPMe-iPr)Cl] (2a) and [Co(PCP-tBu)Cl] (2b), respectively, react readily with NaBH4 to afford complexes [Co(PCPMe-iPr)(η2-BH4)] (4a) and [Co(PCP-tBu)(η2-BH4)] (4b) in high yields, as confirmed by IR spectroscopy, X-ray crystallography, and elemental analysis. The borohydride ligand is symmetrically bound to the cobalt center in η2-fashion. These compounds are...
A new metal borohydride ammoniate (MBA), Zr(BH4)4·8NH3, was synthesized via ammoniation of the Zr(BH4)4 crystal. Zr(BH4)4·8NH3 has a distinctive structure and the highest coordination number of NH3 groups among all the known MBAs. This compound could quickly dehydrogenate at 130 °C, enabling it a potential hydrogen storage material.
A convenient and gentle procedure was used for in vitro radioisotopic labeling the proteins of Newcastle disease virus. This method, which utilizes [14C]formaldehyde and sodium borohydride, labels all the proteins of purified Newcastle disease virus. Virions labeled in this manner retained biological and biopysical integrity
