    Abstract: A template-free reverse micelle (RM) based method is used to synthesize pyrochlore nanostructures having photocatalytic activity. In one embodiment, the method includes separately mixing together a first acid stabilized aqueous solution including pyrochlore precursor A and a second acid stabilized aqueous solution including pyrochlore precursor B with an organic solution including a surfactant to form an oil-in-water emulsion. Next, equimolar solutions of the first and second acid stabilized oil-in-water emulsions are mixed together. Then, the mixture of the first and second acid stabilized oil-in-water emulsion is treated with a base to produce a precipitate including pyrochlore precursors A and B. After which, the precipitate is dried to remove volatiles. The precipitate is then calcined in the presence of oxygen to form a pyrochlore nanostructure, such as a bismuth titanate (Bi2Ti2O7) pyrochlore nanorod.

  • Publication number: 20120094075
    Abstract: A method of obtaining a substrate coated on a first face with at least one transparent and electrically conductive thin layer based on at least one oxide, including depositing the at least one thin layer on the substrate and subjecting the at least one thin layer to a heat treatment in which the at least one layer is irradiated with aid of radiation having a wavelength between 500 and 2000 nm and focused on a zone of the at least one layer, at least one dimension of which does not exceed 10 cm. The radiation is delivered by at least one radiation device facing the at least one layer, a relative displacement being created between the radiation device and the substrate to treat the desired surface, the heat treatment being such that resistivity of the at least one layer is reduced during the treatment.
