Microemulsion mediated synthesis of BaTi03-Ag nanocomposites

Synthesis and Characterization of Ag/PVP Nanocomposites by Reduction Method

A polyvinylpyrrolidone (PVP)/Ag nanocomposite was prepared by reduction of silver nitrate in ethylene-glycol in the presence of a polymeric protective agent (i.e., poly (N-vinylpyrrolidone)). The size dependent color variation of this nanocolloid is a clear indication of the presence of Ag as nanoparticles in the polymer matrix. The nonlinear optical properties were studied by Z-scan technique ...

Synthesis, characterization and multifunctional properties of plasmonic Ag-TiO2 nanocomposites.

We report on the synthesis of multifunctional Ag-TiO2 nanocomposites and their optical, physio-chemical, surface enhanced Raman scattering (SERS) and antibacterial properties. A series of Ag-TiO2 nanocomposites were synthesized by sol-gel technique and characterized by x-ray diffraction, scanning and transmission electron microscopy, energy-dispersed x-ray analysis, photoluminescence, UV-vis, x...

Dielectric Barrier Discharge (DBD) Plasma Assisted Synthesis of Ag₂O Nanomaterials and Ag₂O/RuO₂ Nanocomposites.

Silver oxide, ruthenium oxide nanomaterials and its composites are widely used in a variety of applications. Plasma-mediated synthesis is one of the emerging technologies to prepare nanomaterials with desired physicochemical properties. In this study, dielectric barrier discharge (DBD) plasma was used to synthesize Ag₂O and Ag₂O/RuO₂ nanocomposite materials. The prepared materials showed good c...

Synthesis, Characterization, and Properties of Microemulsion-Mediated Nanophase Ti02 Particles

Nanophase Ti02 particles, with typical particle sizes in the range of 20-50 nm, have been synthesized using a microemulsion-mediated process. In this process, the aqueous cores ofwater/TritonX-100/exanol/ cyclohexane microemulsions have been used as constrained microreactors for the precipitation of precursor titanium hydroxide. The hydroxide particles thus formed were separated, dried, and cal...
