Bioreactor validation and biocompatibility of Ag/poly(N-vinyl-2-pyrrolidone) hydrogel nanocomposites
(Elsevier Science Bv, Amsterdam, 2013)
Silver/poly(N-vinyl-2-pyrrolidone) (Ag/PVP) nanocomposites containing Ag nanoparticles at different concentrations were synthesized using gamma-irradiation. Cytotoxicity of the obtained nanocomposites was determined by MU ...
Potential of Trametes species to degrade lignin
(Elsevier Sci Ltd, Oxford, 2013)
Well developed ligninolytic enzyme system in white-rot mushrooms is responsible for degradation of low degradable and lignin rich unused plant debris, which represents serious environmental ballast. The biological degradation ...
Determination and analysis of the dynamic loaded screws by structural analysis, fractography and numerical simulation
(Trans Tech Publications Ltd, Durnten-Zurich, 2013)
This paper analysis the cause's dynamically loaded screws failure, using the structural analysis of mechanical properties and numerical simulation. The comparison with the new unbroken screws, which were not in use, has ...
Investigation of silver impact on hydroxyapatite/lignin coatings electrodeposited on titanium
(Elsevier Science Sa, Lausanne, 2013)
Silver doped hydroxyapatite (HAP) [Ca9.95Ag0.05(PO4)(6)(OH)(2)] composite coatings with natural polymer organosolv lignin (Lig) were produced by electrophoretic deposition (EPD) on titanium. Coatings were characterized by ...
Solubility of thymol in supercritical carbon dioxide and its impregnation on cotton gauze
(Elsevier Science Bv, Amsterdam, 2013)
Through this study, an attempt has been made to evaluate the solubility of thymol in supercritical carbon dioxide as well to investigate a prospect of its impregnation on cotton gauze on laboratory scale. Solubility of ...
Photocatalytic Degradation of Dye CI Direct Blue 78 Using TiO2 Nanoparticles Immobilized on Recycled Wool-Based Nonwoven Material
(Wiley, Hoboken, 2013)
This paper discusses the possibility of immobilization of TiO2 nanoparticles onto recycled wool-based nonwoven material, which can be utilized for removal of dyes from wastewater. The photocatalytic activity of TiO2 ...
Isopiestic determination of the osmotic and activity coefficients of the {yKBr + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2013)
The molality-based osmotic coefficients of aqueous mixtures of KBr and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method at KBr ionic strength fractions y = (0.18328, 0.38241, 0.58031, 0.79186, ...
Corrosion Stability and Bioactivity in Simulated Body Fluid of Silver/Hydroxyapatite and Silver/Hydroxyapatite/Lignin Coatings on Titanium Obtained by Electrophoretic Deposition
(Amer Chemical Soc, Washington, 2013)
Hydroxyapatite is the most suitable biocompatible material for bone implant coatings. However, its brittleness is a major obstacle, and that is why, recently, research focused on creating composites with various biopolymers. ...
In situ generation of Ag nanoparticles on polyester fabrics by photoreduction using TiO2 nanoparticles
(Springer, New York, 2013)
This study discusses the possibility of in situ generation of Ag nanoparticles on polyester fabric by photoreduction of Ag+ ions with deposited TiO2 nanoparticles in the presence of amino acid alanine and methyl alcohol. ...
Poly(methacrylic acid) based hydrogels as sorbents for removal of cationic dye basic yellow 28: Kinetics, equilibrium study and image analysis
(Elsevier Science Sa, Lausanne, 2013)
Poly(methacrylic acid) based hydrogels with neutralization degree of monomer of 0% (PMAA/0) and 80% (PMAA/80) were synthesized and their sorption potentials toward model cationic dye, basic yellow 28 (BY28), from aqueous ...
