Preparation and Characterization of Silver-Loaded Hemp Fibers with Antimicrobial Activity
(Korean Fiber Soc, Seoul, 2014)
The objective of this research was to impart antimicrobial properties to hemp fibers by incorporation of silver ions in hemp fibers by chemisorption. Sorption properties of hemp fibers were improved by non-selective oxidation ...
Synthesis of pure and La-doped anatase nanopowders by sol-gel and hydrothermal methods and their efficiency in photocatalytic degradation of alprazolam
(Elsevier Ltd., 2014)
Pure and La3+ doped titanium dioxide (TiO2) nanopowders were obtained by sol gel and hydrothermal methods. A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both ...
Influence of amine activators and reaction parameters on grafting reaction between polystyrene and starch
(Springer, Dordrecht, 2014)
Polystyrene graft corn starch copolymers (PS-g-starch) were synthesized by emulsion polymerization using sodium dodecylsulfate (SDS) as the emulsifier and potassium persulfate (PPS) as the initiator. Influences of temperature ...
Silver/Poly(N-vinyl-2-pyrrolidone) Hydrogel Nanocomposites Obtained by Electrochemical Synthesis of Silver Nanoparticles Inside the Polymer Hydrogel Aimed for Biomedical Applications
(Wiley, Hoboken, 2014)
Silver nanoparticles were produced inside a poly(N-vinyl-2-pyrrolidone) hydrogel (PVP) by an innovative method based on the electrochemical reduction of Ag+ ions within the swollen PVP hydrogel. UV-visible spectroscopy ...
Cytotoxicity studies of novel Ag/alginate nanocomposites aimed for wound treatment
(Wiley-Blackwell, Hoboken, 2014)
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, ...
Thermal treatment influence on the surface characteristics of the boron-doped hydrothermal carbon
(Society of Physical Chemists of Serbia, 2014)
Boron-doped carbons were produced using hydrothermal carbonization of
glucose carbohydrates under mild temperature (180oC). Boric acid was
introduced into glucose precursor solution in order to obtained boron
concentration ...
Photocatalytic Degradation of C. I. Acid Orange 7 by TiO2 Nanoparticles Immobilized onto/ into Chitosan- Based Hydrogel
(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 ...
Fermentative activity and viability of immobilized probiotic starter culture ABY-6 in whey based substrates
(Novi Sad : University, Institute of Food Technology, 2014)
The aim of this paper was to study fermentative activity by free and immobilized probiotic ABY-6
culture in whey substrate enriched with milk. Viability of free and immobilized probiotic cells in
simulated gastrointestinal ...
