Synthesis and characterization of silver/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposite obtained by in situ radiolytic method
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
This work describes radiolytic synthesis of silver nanoparticles (Ag NPs) within the poly(N-vinyl-2-pyrrolidone) (PVP) hydrogel. The hydrogel matrix was obtained by gamma irradiation-induced cross-linking, while the in ...
The formation of oxide nanoparticles on the surface of natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Nanoparticles of NiO, ZnO and Cu(2)O crystallize when the Ni-, Zn- and Cu-exchanged natural clinoptilolite, respectively, are dehydrated by heating in air at 550 degrees C. The dehydration of Mn-exchanged clinoptilolite ...
Nanocomposite microfibers based on alginate and PVA hydrogels with incorporated silver nanoparticles
(Wiley-Blackwell, Hoboken, 2012)
In vitro investigation of cytotoxicity and antimicrobial activity of silver/alginate nanocomposite microbeads
(Wiley-Blackwell, Hoboken, 2012)
Extraction of phenolic compounds from agro-industrial wastes and evaluation of their antioxidative potential
(Skopje, Macedonia : Consulting and Training Center - KEY, 2021)
Constant world population growth imposes the need for the production of more food, and as a consequence, has an increase in the organic-rich wastes. These agro-industrial wastes represent problem from the environmental ...
Microstructure of new composite electrocatalyst and its anodic behavior for chlorine and oxygen evolution
(Elsevier Sci Ltd, Oxford, 2012)
The first layer of active coating made from a rutile-structured solid solution of ruthenium and titanium dioxides having an average crystal grain size of 30 nm was thermally deposited on an adequately prepared titanium ...
Influence of picosecond laser pulses on the microstructure of austenitic materials
(Springer, New York, 2011)
We investigate samples of austenitic materials - stainless steel and iron-based superalloy - which are widely used at high temperatures and pressures. The samples were exposed to Nd(3+):YAG laser pulses with a wavelength ...
Tio2/zro2 thin films synthesized by pld in low pressure n-, c- and/or o-containing gases: structural, optical and photocatalytic properties
(Inst Materials Physics, Bucharest, 2012)
Doped TiO2/ZrO2 films were obtained by Pulsed Laser Deposition method under different synthesis conditions. The onset of absorption spectra was red shifted for the films obtained in N-2 containing gas mixtures, while a ...
Optimization of modifier deposition on the alumina surface to enhance mechanical properties and cavitation resistance
(Springer, New York, 2020)
Composites based on poly(methyl methacrylate), dimethyl itaconate matrix and alumina particles were prepared. Ferrous oxide-doped alumina particles (Al2O3Fe) and commercial alumina nanoparticles (Al(2)O(3)n) modified with ...
Development of advanced floating poly(lactic acid)-based materials for colored wastewater treatment
(Journal of Supercritical Fluids, 2021)
The release of industrial wastewater into the ecosystem prompted our research on the development of an efficient and biodegradable material that can be used for wastewater treatment. We optimized preparation of porous ...
