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...

The performance of an alkaline fuel cell is investigated using three different fuels, e g., methanol, ethanol and sodium borohydride. Pt/C/Ni was used as anode whereas Mn/C/Ni was used as standard (Electro-Chem-Technic, UK) cathode for all the fuels. Thus, the alkaline fuel cell is used for multi-fuel system. Fresh mixture of electrolyte, potassium hydroxide (5M), and fuel (2M) was fed to and w...

An enzyme from Vibrio 01 catalyzing cis-tram isomerization of maleylacetone has been identified and pursed. The enzyme has a molecular weight of about 35,000 and appears to be a single unit. Its density is low compared to other proteins. Glutathione is specifically required as a coenzyme. Treatment of the enzyme with sodium borohydride in the presence of substrate and GSH leads to increased act...

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...

Titanium dioxide is a very attractive material in catalysis. Although the titanium exhibits superior proper-ties ultra violet radiation, activity of catalyst can be improved by some modifications specially for daylight radiation. was colored thermal decomposition sodium borohydride at 400 0C. The gray nanotube-titanium obtained where molar ratio to borohydride, 1.2 and 0.6. black prepared makin...

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 ...
