gold nanoparticles were synthesized in DMF (N, N-dimethylformamide) solution by using 3-(aminopropyl)triethoxysilane as stabilizer through wet chemical route. A characteristic surface plasmon band can be observed for the obtained gold nanoparticles from UV-vis absorption spectra, which indicate that KH-550 can serve as stabilizing agent for the formation of gold nanoparticles. The influence of reaction temperature, reaction time and precursor concentrations on the formation of gold nanoparticles is investigated through UV-vis absorption spectra. The results show that surface plasmon absorption peak could be red-shifted when reaction temperature, reaction time and precursor concentrations increase. Transmission electron microscopy (TEM) results show that the obtained gold nanoparticles with spherical morphology have a narrow size distribution.

Silica based ceramics are some of the most fundamental in crystal chemistry. The cristobalite form of silica has two modifications, α (low temperature, tetragonal form) and β (high temperature, cubic form). This paper describes our structural studies of unusual chemically stabilized cristobalite (CSC) material, a room temperature silica-based ceramic containing small amounts of dopants, prepared by a wet chemical route. It displays many of the structural charatcteristics of the high temperature β-cristobalite (∼270°C), but does not undergo phase inversion to α-cristobalite upon cooling. The Structure of α-cristobalite is well established, but that of β is not yet fully understood.Compositions with varying Ca/Al ratio and substitutions in cristobalite were prepared in the series, CaO:Al2O3:SiO2 : 3-x: x : 40, with x= 0-3. For CSC, a clear sol was prepared from Du Pont colloidal silica, Ludox AS-40®, aluminium nitrate nonahydrate, and calcium nitrate hexahydrate in proportions to form a final composition 1:2:40 composition.
