Dilution of sera containing gentamicin or tobramycin in glass containers results in substantial adsorption of the antibiotic to the surface of the container, which can be prevented if acidic or basic solutions are used to dilute such sera. We describe protocols for radioimmunoassays of gentamicin and tobramycin that include solutions and containers that obviate this problem.

Truly environmentally friendly means of detoxifying chemical warfare agents have yet to be developed. Toward this end, Soman (GD), VX and agent simulants were treated with aqueous aluminum sulfate (alum), sodium aluminate, or mixtures of the two. The mixtures were prepared by combining varying volumes of the aqueous salts to give buffered solutions (pH 2-12). Reactions were tracked using phosph...

uv/tio2 photocatalysis of chelated copper in aqueous solutions has been performed starting from cu(ii)-tartaric acid, cu(ii)-citric acid, cu(ii)-edta and cu(ii)-dtpa,in the presence of oxygen and at acidic ph. the photocatalytic reaction obeys first-order kinetic equation. the influence of cu(ii) on photocatalytic oxidation of organic ligands and how the various organics will affect the treatmen...

Electrochemically activated solutions (ECAS) are generated by electrolysis of NaCl solutions, and demonstrate broad spectrum antimicrobial activity and high environmental compatibility. The biocidal efficacy of ECAS at the point of production is widely reported in the literature, as are its credentials as a "green biocide." Acidic ECAS are considered most effective as biocides at the point of p...

Polydispersed dinickel phosphide (Ni2P) nanoparticles were synthesized by a simple and scalable solid-state reaction. These nanoparticles are an excellent and robust catalyst for the electrochemical hydrogen evolution reaction, operating in both acidic and basic solutions.
