Zn aqueous batteries typically suffer from poor cycle life because water soluble zincate ions are formed during the oxidation of Zn. When Zn is oxidized, most of the Zn2+ ions detach from the current collector and become electrochemically inactive, leaving the battery non-rechargeable. Numerous reports demonstrate the use of Bi2O3 as an electrode additive to enhance electrochemical performance ...

Bismuth - sulphur quantum dots can be silver enhanced by autometallography (AMG). In the present study, autometallographic silver enhanced bismuth-sulphur nanocrystals were isolated from unfixed cryo-sections of kidneys and livers of rats exposed to bismuth (Bi207) subnitrate. After being subjected to AMG all the organic material was removed by sonication and enzymatic digestion and the silver ...

Bismuth telluride nanowires are of interest for thermoelectric applications because of the predicted enhancement in the thermoelectric figure-of-merit in nanowire structures. In this letter, we carried out temperature-dependent thermal diffusivity characterization of a 40 nm diameter Bi2Te3 nanowires/alumina nanocomposite. Measured thermal diffusivity of the composite decreases from 9.2310−7 m2...

Nano -and microcrystalline bismuth metal powders consisting of spherical particles with a size 150-250 nm were obtained by reducing formates in an ethylene glycol medium. The phase composition and morphology the reaction products studied X-ray thermal analysis, differential scanning calorimetry, transmission electron microscopy. Using Uv-vis, it was shown that bismuth-ethylene complex is formed...
