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 ...
Evaluation and improvement of antioxidant and antibacterial activities of supercritical extracts from clove buds
(Elsevier, Amsterdam, 2013)
For the first time, extracts from clove buds obtained by supercritical carbon dioxide extraction were screened for antioxidant and antibacterial activities. Additionally, antioxidant and antibacterial activities of extracts ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO·ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Silver incorporation on viscose and cotton fibers after air, nitrogen and oxygen DBD plasma pretreatment
(Springer, Dordrecht, 2013)
Dielectric barrier discharge (DBD) pretreatments in air, nitrogen and oxygen plasma of viscose and cotton fabrics with subsequent immobilization of silver were studied. Surface activation of treated fibers was evaluated ...
Inhibition properties of self-assembled corrosion inhibitor talloil diethylenetriamine imidazoline for mild steel corrosion in chloride solution saturated with carbon dioxide
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The inhibition effect of talloil diethylenetriamine imidazoline (TOFA/DETA imidazoline) on corrosion of mild steel in chloride solutions saturated with CO2 was investigated by weight loss measurements (WL) and atomic force ...
Functionalization of textile materials with TiO2 nanoparticles
