โฆ Synopsis
polyaniline. The rate of metal salt reduction and the size of the metal particles were found to be strongly dependent on the medium used, the initial ratio of metal ions to polyaniline, and the reaction time. The polyaniline-metal particle systems were characterized using X-ray photoelectron spectroscopy, UV-visible absorption spectroscopy, and FTIR spectroscopy. Scanning and transmission electron microscopy and laser light scattering were used to determine the size of the metal particles in polyaniline.

Nanoparticles of tin oxide (SnO 2 ) have been prepared from water-in-oil microemulsions consisting of water, AOT (surfactant), and n-heptane (oil). Precursor hydroxides were precipitated in the aqueous cores of water-in-oil microemulsions and then calcined at 600ยฐC for 2 h to form tin oxide powder.
We report studies of the effect of hydrothermal treatment on physical properties such as crystalline phase, size, and morphology of nanosized cadmium sulfide (CdS) particles. CdS precipitates have been synthesized by the reaction of Cd(NO 3 ) 2 with Na 2 S at room temperature. These CdS precipitates
Ultrafine metal particle-supported carbon particles were synthesized by pyrolysis of polymer particle-metaI ions such as Co(II), Ni(II), Cu(II), Ag, Pd(II), and Rh(II1) complexes. The sizes of metal particles increased with increasing pyrolysis temperature. P d and Rh particles were on the whole sma
