In this study, the modification of macroporous α-Al2O3 ceramics with AlOOH nanostructures impregnated silver particles is carried out using bicomponent Al/Ag nanoparticles obtained by simultaneous electrical explosion Al and Ag wires. Nanoparticle suspension impregnation porous followed oxidation water shown to lead formation a continuous nanosheet coating on ceramic surface, releasing surface ...

The kinetics of Ag nanoparticle photogeneration inside optically transparent thin polymer films was studied. Light sensitive polymer films able to initiate the reduction of Ag ions were prepared by blending poly(vinyl alcohol), PVA, and sulphonated poly(ether etherketone), SPEEK. Photolysis of such films with 350 nm photons produced benzophenyl ketyl (BPK) radicals of SPEEK, which are strong re...

Silver-Polyaniline (Ag-PANI) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (AOT) solution as an emulsifier. The synthesis of Silver-Polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (AOT), concentration of oxidation agent and c...

In this work, we apply a molecular dynamics simulation of Ag-nanoparticle-doped epoxy resin to analyze in depth the micro-mechanisms nanodielectric. The results show that when Ag nanoparticles with radius 10Å are used as dopants, periodically arranged atoms ~4.5-Å-thick surface layer have become amorphous. This modification interface depends on temperature and nanoparticle size leads an polariz...

in the present paper, the flow and heat transfer of two types of nanofluids, namely, silver-water and silicon dioxide-water, were theoretically analyzed over an isothermal continues stretching sheet. to this purpose, the governing partial differential equations were converted to a set of nonlinear differential equations using similarity transforms and were then analytically solved. it was found...

In this study, the nonlinear optical properties and optical limiting performance of the silver nanoparticles (AgNPs) in distilled water are investigated. The nonlinear absorption coefficient of the colloid is measured by the Z-scan technique. The optical limiting behavior of the AgNP suspension is investigated under exposure to nanosecond laser pulses at 532 nm. The results show that nonlinear ...

a facile and green approach has been developed to synthesize silver nanoparticle (ag-nps). this was carried out by a biosynthetic route using justicia adhatoda root extract as reducing and stabilizing agent. the structure, composition, average particle size (~25 nm) and surface morphology of ag-nps were characterized by the x-ray diffraction, transmission electron microscope and atomic force mi...
