We perform a detailed investigation of coatings made of poly(p-xylylene) nanocomposites with embedded silver nanoparticles of sizes up to 12 nm and concentration up to 10.5 vol. %. We study their microstructure, mechanical, optical, and radiative characteristics. We reveal certain correlations between structural peculiarities and optical, as well as radiative properties. These correlations are due...
In this research, novel nanocomposite scaffolds with compositions based on cross-linked gelatin (Gel) and bioactive glass (BaG) nanoparticles in the ternary SiO2-CaO-P2O5 system were prepared and fully characterized. The scanning electron microscopy (SEM) observations revealed that the prepared scaffolds were porous with three dimensional (3D) and interconnected microstructure, pore size was 200-500...
The nanocomposite Ti-Si-N thin flims were prepared by reactive magnetron co-sputtering system. The experimental parameter effect on the evolution of mechanical property of nanocomposite TiSiN Films was investigated. The Ti-Si-N film is a mixed composite consisting of the Ti-Si, Ti-N and Si-N compounds. As Si is added to the polycrystalline Ti-N compound to form Ti-Si-N, the microstructure becomes...
In this paper, the resistivity and temperature coefficient of resistance (TCR) of nanostructured Ta-Si-N thin films fabricated on silicon substrate by reactively cosputtering have been studied. The substrate bias was controlled from 0 to -200 V at a fixed nitrogen flow ratio of 5 FN2% (FN2/ (FN2+FAr) times 100%) to study the electrical properties of different Ta-Si-N films. The Ta-Si-N films with...
In this study, the nanocomposite Ti-Si-N thin films were prepared by reactive magnetron co-sputtering system. The Ti-Si-N film is a mixed composite consisting of the Ti-Si, Ti-N and Si-N compounds. The TiN phase is polycrystalline while SiNx is amorphous. As Si is added to the Ti-N compound to form Ti-Si-N, the microstructure becomes nanocrystalline grains embedded in an amorphous matrix i.e. nanocomposite...
In this study, Sn-0.7Cu solder alloy was reinforced with Al2O3 (50 nm) and ZrO2 (45 nm) nano particulates to form Sn-0.7Cu/Al2O3 and Sn-0.7Cu/ZrO2 composites. The volume percentge of the Al2O3 and ZrO2 nanoparticulate reinforcement was kept at 1.5%. The composites were synthesized using powder metallurgy technique assisted with microwave sintering and incorporating hot extrusion as secondary processing...
In this work, pulsed laser annealing (PLA) was preformed on ion-beam-synthesized Ag-SiO2 nanocomposites to improve the FE properties of these samples by modifying the size and distribution of the Ag nanoclusters. The PLA was preformed using a 248 nm KrF excimer laser. Multiple pulses, with durations of 25 ns, at an energy density of 250 mJ/cm were accumulated onto the sample. The FE properties of...
The polyethylene/montmorillonite nano-composites are prepared by melting intercalation process. The morphology and dielectric properties of the nano-composites are investigated by means of X-ray Diffraction (XRD), scanning electronic microscope (SEM), atomic force microscope (AFM) and dielectric analyzer etc. The results indicated that polyethylene can be intercalated in organically modified montmorillonite...
