a novel pyridine-2,6-dicarboxylic acid mixed ligands complex of formula [co(no3)2].6h2o has been obtained by the reaction of pyridine-2,6-dicarboxylic acid with cobalt nitrate and 1,10-phenanthroline on heating in water. the structures of [co(pydc)(phen)(h2o)](pydch2).4h2o receptors, and their complexes were optimized using dft method at the b3lyp/3-21g** level. the highest occupied molecular o...

In the present investigation the effect of cobalt chloride (CoCl ), ethylene biosynthesis inhibitor and 2 silver nitrate (AgNO ), ethylene perception inhibitor was studied on the seed germination of Vigna radiata. 3 While ethylene slightly promoted germination, both the inhibitors decreased the germination percentage. However, Ag was more effective in retarding germination than Co . A combined ...

β-SiC-supported cobalt catalysts have been prepared from nitrate, acetate, chloride and citrate salts to study the dependence of Fischer–Tropsch synthesis (FTS) on the type of precursor. Com/SiC catalysts were synthetized by vacuum-assisted impregnation while N2 adsorption/desorption, XRD, TEM, TPR, O2 pulses and acid/base titrations were used as characterization techniques. FTS catalytic perfo...

OBJECTIVE To determine the effects of cobalt nitrate on the arterial wall in a rat femoral artery vasospasm model. STUDY DESIGN Experimental study. PLACE AND DURATION OF STUDY Faculty of Medicine, Istanbul University, between November 2009 and September 2010. METHODOLOGY Twenty-four rats were separated into three groups named group 1 (n=8, sham-control); group 2 (n=8, vasospasm), and grou...

Silica nanoparticles were directly coated with cobalt hydroxide by homogeneous precipitation of slowly decomposing urea in cobalt nitrate solution. The cobalt hydroxide was amorphous, and its morphology was nanoflower-like. The BET (Brunauer-Emmett-Teller) surface area of the core-shell composite was 221 m²/g. Moreover, the possible formation procedure is proposed: the electropositive cobalt io...
