Novel magnetic nanohybrids composed of nanomaghemite covered by organic molecules were successfully synthesized at room temperature with different functionalization agents (sodium polystyrene sulfonate, oxalic acid, and cetyltrimethylammonium bromide) in low high concentrations. Structural, vibrational, morphological, electron energy-loss spectroscopy, magnetic, Mössbauer characterizations unraveled the presence mainly cubic inverse spinel maghemite (γ-Fe
Glasses containing metallic nanoparticles are promising materials that should also possess the best spectroscopic, chemical, mechanical and thermal characteristics for technological applications in optics photonics. For this reason it was chosen to synthesize characterize pure silver doped borosilicate glasses nitrate. The present work investigates generation of on surface mass a glass which directed synthesis process consisted: stoichiometric calculations, determination melting temperature,...
The direct electrodeposition of CoFeNiMoW high entropy alloy (HEA) thin films from aqueous medium is demonstrated. By employing a citrate-containing bath and varying the applied current density (ic), HEAs with different compositions are obtained. Specifically, composition HEA film obtained at ic = 50 mA cm-2 Co30Fe21Ni19Mo25W5. physical characterization performed by energy dispersive x-ray spectrometry (EDS), grazing incidence diffraction (GIXRD), 57Fe Mössbauer spectroscopy. Results confirm...
