A comprehensive approach to in vitro functional evaluation of Ag/alginate nanocomposite hydrogels
(Elsevier Sci Ltd, Oxford, 2014)
In this work, we present a comprehensive approach to evaluation of alginate microbeads with included silver nanoparticles (AgNPs) at the concentration range of 0.3-5 mM for potential biomedical use by combining cytotoxicity, ...
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 ...
Effect of Deposition Current Density and Annealing Temperature on the Microstructure, Hardness and Magnetic Properties of Nanostructured Nickel-Iron-Tungsten Alloys
(Electrochemical Soc Inc, Pennington, 2014)
Nanostructured nickel-iron-tungsten alloy coatings were electrodeposited from an ammonia citrate bath on steel and copper substrates at current densities in the range of 50 to 300 mA cm(-2). The contents of iron and tungsten ...
Trends in Encapsulation Technologies for Delivery of Food Bioactive Compounds
(Springer, New York, 2015)
The food industry expects increasingly complex properties (such as delayed release, stability, thermal protection, and suitable sensorial profile) from food ingredients, which often would not be able to be achieved without ...
Biological activity of electrochemically synthesized silver doped polyvinyl alcohol/graphene composite hydrogel discs for biomedical applications
(Elsevier Sci Ltd, Oxford, 2016)
Silver/poly(vinyl alcohol), Ag/PVA, and silver/poly(vinyl alcohol)/graphene, Ag/PVA/Gr, composite hydrogel discs were produced by freezing/thawing, followed by electrochemical reduction of Ag+ ions inside respective matrices, ...
Sonophotocatalytic degradation of dye CI Acid Orange 7 by TiO2 and Ag nanoparticles immobilized on corona pretreated polypropylene non-woven fabric
(Elsevier, Amsterdam, 2015)
This study discusses the possibility of using corona pre-treated polypropylene (PP) non-woven fabric as a support for immobilization of colloidal TiO2 and Ag nanoparticles in order to remove dye C.I. Acid Orange 7 from ...
Lignin degradation by selected fungal species
(Elsevier Sci Ltd, Oxford, 2013)
As biological decomposition of plant biomass represents a popular alternative environmental-friendly and economically justified process, screening of ligninolytic enzyme systems of various fungal species is a topical study ...
Waste animal fats as feedstocks for biodiesel production
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Biodiesel, an alternate and ecologically acceptable substitute for the conventional fuel, is usually produced from a wide range of edible vegetable oils, which are normally used for human consumption and whose prices are ...
In situ synthesis of Cu/Cu2O nanoparticles on the TEMPO oxidized cotton fabrics
(Springer, Dordrecht, 2018)
In situ synthesis of Cu/Cu2O nanoparticles on the cotton fabric discussed in this study relies on adsorption of Cu2+-ions by carboxylate groups generated through the TEMPO-mediated oxidation of cellulose and their subsequent ...
Lactic acid production on molasses enriched potato stillage by Lactobacillus paracasei immobilized onto agro-industrial waste supports
(Elsevier Science Bv, Amsterdam, 2018)
In this study, the production of lactic acid (LA) on sugar beet molasses enriched potato stillage by immobilized Lactobacillus paracasei NRRL B-4564 was examined. Three agro-industrial materials, such as sunflower seed ...
