Precious metal alloys enables new possibilities to tailor materials for specific optical functions. Here we present a systematic study of the effects of a nanoscale alloying on the permittivity of Au-Ag-Cu metals at 38 different atomic mixing ratios. The permittivity was measured and analyzed numerically by applying the Drude model. X-ray diffraction (XRD) revealed the face centered cubic latti...

Nanocrystalline undoped and 5% Mn doped ZnO powders are synthesized by sol-gel route using constituent nitrate and citrate precursors. The physico-chemical characterizations of powders calcined at various temperatures (400-1100 ̊C), are performed using techniques (XRD and SQUID) to study structural, nano/microstructural, and magnetic properties. XRD patterns clearly revealed the evolution of ma...

Maghemite (γ-Fe2O3) nanoparticles have been synthesized using chemical co-precipitation at a different temperature. Characterizations of the sample were performed by X-ray diffraction (XRD), transmission electron microscopy (TEM), alternating gradient magnetometry (AGM) and thermogravimetryanalysis (TGA). The stability of the maghemite nanoparticles suspension was studied at different pH and ti...

The Rietveld Method was used to investigate the structure of three Fe-Zn intermetallic phases and to quantify their proportion. The zeta, delta and gamma phases were successfully obtained by the sintering process. A simple mixture of the three intermetallic phases was made with a known mass percentage and the XRD pattern of this mixture was collected and analyzed by the Rietveld Method. A diffe...

High density sodium lithium niobate lead free ceramics near the morphtropic phase boundary [NaxLi1−xNbO3, (LNN), x=0.12] were prepared by the solid state reaction method. XRD patterns showed that the lattice structures were changed after polarization. The temperature dependence of the dielectric constant and dielectric loss, pyroelectric coefficient and DSC curves of LNN ceramics showed that th...

PbSrWO4 and PbBaWO4 have been synthesised by the solid state reaction technique XRD patterns show them to be tetragonal. Dielectric constant (K/) and Dielectric loss (K//) of PbSrWO4 and PbBaWO4 have been measured at 1 kHz in the temperature range of 300 to 1050 K. The log K/ vs T as well as log K// vs T plot of PbSrWO4 and PbBaWO4 shows rapid increase of dielectric constant above 590 K and 640...

The reduction of aluminium trichloride by lithium aluminium hydride in the presence of poly(vinylpyrrolidone) or poly(methylmethacrylate) in mesitylene yielded nano aluminium particles in the matrices of respective polymers. Solution phase synthesis methodology was used successfully to produce composites of various Al/polymer ratios. The composites were characterized by powder XRD patterns and ...
