It has been found that low doses of certain toxicants might generate a protective response to cellular damage. Previous data have shown that elevated doses of cobalt (Co) induce injury to cells and organisms or result in radiological combined toxicity. Whether low doses of Co generate a protective effect or not, however, remains controversial. In this study, we investigated the effect and mecha...

Novel eutectic mixtures have been produced using calcium chloride hexahydrate as the hydrogen bond acceptor, together with ethylene glycol donor. The liquids are found to increased conductivity, decreased viscosity and a lower glass transition temperature compared most deep solvents quaternary ammonium salts. Additionally, metal speciation was be almost same in commonly-used choline chloride: D...

The development of efficient and stable water oxidation catalysts is necessary for the realization of practically viable water-splitting systems. Although extensive studies have focused on the metal-oxide catalysts, the effect of metal coordination on the catalytic ability remains still elusive. Here we select four cobalt-based phosphate catalysts with various cobalt- and phosphate-group coordi...

We demonstrated that single-crystalline cobalt monoxide (CoO) hollow spheres and octahedra could be selectively synthesized via thermal decomposition of cobalt(II) acetylacetonate in 1-octadecene solvent in the presence of oleic acid and oleylamine. The morphologies and sizes of as-prepared CoO nanocrystals could be controlled by adjusting the reaction parameters. Cobalt oxide (Co(3)O(4)) hollo...

Experiments were designed to investigate the metabolism of Cyclophosphamide in vitro and in vivo following the administration of known stimulators and depressors of rat hepatic microsomal mixed-function oxidase activity, the antitumor efficacy of Cyclophosphamide as a function of its metabolism, and the toxicity of Cyclophosphamide as a function of its metabolism. Regarding the metabolism of Cy...

Cobalt (Co) toxicity is a potential public health problem due to recent renewed use of Co in orthopedic implants, dietary supplements, and blood doping in athletes and horses. We investigated the protective roles of kolaviron (KV), a bi-flavonoid of Garcinia kola, and gallic acid (GA) on cobalt chloride (CoCl2)-induced cardiorenal damage in rats. CoCl2 caused significant increases (p < 0.05) in...

Inhalation of cobalt (Co) and tungsten carbide (WC) particles, but not Co or WC alone, may cause hard metal disease, risk of which does not appear to be uniform across cemented tungsten carbide (CTC) production processes. Inhalation of Co alone or in the presence of WC may cause asthma. Hypothesizing that aerosol size, chemical content, heterogeneity, and constituent compaction may be important...

Tantalum cobalt nitride photocatalysts were prepared using a simple drop coating method on a Ta foil substrate followed by thermal ammonia treatment, and their photoelectrochemical (PEC) properties for water oxidation under visible light were studied. The resulting Ta0.9Co0.1Nx films showed a photocurrent of ca. 1.5 mA/cm (12 times higher than that of Ta3N5) under 100 mW/cm visible light irradi...

Cobalt was recovered electrogeneratively by using a batch cell. In this system, a spontaneous chemical reaction occurred where cobalt is reduced at the cathode and zinc is oxidized to produce a free flow of electrical energy without any external power supply. The performances of reticulated vitreous carbon (RVC) and porous graphite (PG) as cathodes were evaluated based on the time and percentag...
