Spectroelectrochemical sensing a metal in two different oxidation states, both of which are weakly absorbing in the visible wavelength range, was demonstrated with ferrous and ferric ion. The sensor consisted of an indium tin oxide optically transparent electrode (ITO OTE) coated with a thin film of Nafion preloaded with the ligand 2,2'-bipyridine (bipy). Fe2+ in the sample partitioned into the...

This study aims to control the wettability of pure transition metals by liquid sodium or tin. Such was evaluated measuring contact angles with droplet method. Pure titanium, iron, nickel, copper, and molybdenum were selected as specimens in this experiment. All experiments conducted an environment high argon gas extremely low moisture avoid influence oxygen on metals. The measurement temperatur...

abstracta novel floatation-spectrophotometric extraction method was developed for the recovery of tin (ii) from aqueous samples prior to determination by uv spectrophotometric detection. the method is based on the formation of a complex between tin (ii) and kalmagyte in ph=8. the complex is floated in the interface of n-hexane and aqueous phases. after removing the aqueous phase, the floated pa...

The effects of dietary tin on tin and calcium metabolism were determined in eight adult males. Subjects were fed mixed diets containing 0.11 mg tin daily (control diet) and 49.67 mg tin daily (test diet) for 20 days each in a cross-over design. The level of tin in the control diet was typical of the level of tin found in diets that contained only fresh and frozen foods; the level of tin in the ...

Titanium oxynitrides (Ti(N,O,C)) are abundant in xenolithic corundum aggregates pyroclastic ejecta of Cretaceous volcanoes on Mount Carmel, northern Israel. Petrographic observations indicate that most these nitrides existed as melts, immiscible with coexisting silicate and Fe-Ti-C silicide melts; some may also have crystallized directly from the melts. The TiN phase shows a wide range solid so...
