Structure and magnetic properties of electrodeposited Ni87.3Fe11.3W1.4 alloy
(Elsevier, Amsterdam, 2014)
A dark gray nanostructured coating of an alloy composed of 87.3 wt.% Ni, 11.3 wt.% Fe and 1.4 wt.% W (Ni87.3Fe11.3W1.4) was electrodeposited from an ammonia citrate bath on a titanium cathode at a current density of 500 ...
Potential of Pleurotus ostreatus Mycelium for Selenium Absorption
(Hindawi Publishing Corporation, New York, 2014)
The aim of this study was to evaluate the effect of high selenium (Se) concentrations on morphophysiological and ultrastructural properties of Pleurotus ostreatus. Mycelium growth was good in media enriched with 5.0, 10.0, ...
Removal of model cationic dye by adsorption onto poly(methacrylic acid)/zeolite hydrogel composites: Kinetics, equilibrium study and image analysis
(Elsevier, Amsterdam, 2014)
Composites based on poly(methacrylic acid) (PMAA) and two types of zeolite, hydrophilic zeolite A and hydrophobic zeolite ZSM-5, were synthesized. The obtained hydrogel composites that combine well the strong interaction ...
Rapid cationic dye adsorption on polyphenol-extracted coffee grounds-A response surface methodology approach
(Elsevier Science Bv, Amsterdam, 2014)
The Box-Behnken design under the response surface methodology (RSM) with five interacting parameters (adsorbent dose, initial dye concentration, time of agitation, initial solution pH and time of the adsorbent microwave ...
Lipase-Catalyzed Esterification of Phloridzin: Acyl Donor Effect on Enzymatic Affinity and Antioxidant Properties of Esters
(Amer Chemical Soc, Washington, 2014)
Lipase-catalyzed acylation of phloridzin with a wide range of fatty acids and antioxidant activities of synthesized esters were investigated in this study. Polar solvents were suitable reaction media for esterification, ...
Catalyzed Ester Synthesis Using Candida rugosa Lipase Entrapped by Poly(N-isopropylacrylamide-co-itaconic Acid) Hydrogel
(Hindawi Publishing Corp, New York, 2014)
This study reports the synthesis of polymeric matrices based on N-isopropylacrylamide and itaconic acid and its application for immobilization of lipase from Candida rugosa. The lipase was immobilized by entrapment method. ...

(Wiley, Hoboken, 2014)
Photocatalytic degradation of dye C.I. Acid Orange 7 in aqueous solution using TiO2/hydrogel nanocomposite under solar light simulating source was studied. Hydrogel based on chitosan, itaconic and methacrylic acid was ...
Effect of nutrient supplements on growth and viability of Lactobacillus johnsonii NRRL B-2178 in whey
(Elsevier Sci Ltd, Oxford, 2014)
The main objectives of the paper were to study the effects of nutrient supplementation of cows' whey on the growth and viability of the probiotic microorganism Lactobacillus johnsonii NRRL B-2178. Because of the short ...
Quality attributes of a fermented whey-based beverage enriched with milk and a probiotic strain
(Royal Society of Chemistry, 2014)
Beverages produced by fermentation of whey have significantly lower viscosity, milder flavour and less viability of probiotic microorganisms compared to those obtained by fermentation of milk. Therefore, it is necessary ...
The potential application of TiO2/hydrogel nanocomposite for removal of various textile azo dyes
(Elsevier, Amsterdam, 2014)
TiO2/hydrogel nanocomposite has been utilized for investigation of photocatalytic degradation of three different groups of anionic azo dyes in aqueous solutions under solar light simulating source in order to evaluate its ...
