Titania, single-doped and lanthanum-silver co-doped titania nanocomposite were coated on cellulosic and polyacrylonitrile fibers via sol–gel method. The prepared samples were evaluated using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive x-ray spectroscopy (EDX), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), photolumines...

Silver nanoparticles were synthesized via laser ablation in two different organic solvents (tetrahydrofuran and toluene). The influence of solvent choice on the production behavior silver dispersed a polystyrene matrix was investigated. UV–Vis spectroscopy, ellipsometry scanning probe microscopy techniques used for characterization. nanoparticles’ optical properties modified by existence core-s...

Nanoparticles (NPs) of noble metals can strongly absorb visible light because of their plasmon resonance, which is greatly influenced by their morphology and size. The phenomenon of plasmon resonance gives rise to important applications such as colorimetric sensors, photovoltaic devices, photochromic devices, and photocatalysts. Noble metal NPs exhibit characteristic optical and physical proper...

Abstract Nanopowders doped with silver were produced by the method of pulsed electron beam evaporation. The pore sizes nanoparticles 25-32 nm. Evaluation photocatalytic and cytotoxic properties on cells was carried out. prospects using multimodal nanopowders as a agent, well for use in medicine, have been shown.

Abstract The work is devoted to the creation of a laser method for monitoring virucidal properties nanocoatings medical instruments. relationship between intensity spectra washes from silver-doped coatings and concentration pathogens was studied. Plasmon resonance obtained using DFB in order be able develop this method.

Staphylococcus aureus can cause a range of diseases, such as osteomyelitis, as well as colonize implanted medical devices. In most instances the organism forms biofilms that not only are resistant to the body's defense mechanisms but also display decreased susceptibilities to antibiotics. In the present study, we have examined the effect of increasing silver contents in phosphate-based glasses ...

${\mathrm{AgF}}_{2}$ is a correlated charge-transfer insulator with properties remarkably similar to insulating cuprates, which have raised hope that it may lead new family of unconventional superconductors upon doping. We use ab initio computations study doping strategies leading metallization. Because the upper Hubbard band very narrow electron leads undesired strongly self-trapped states (po...
