Metal removal of cyanobacterial exopolysaccharides by uronic acid content and monosaccharide composition
(Elsevier Sci Ltd, 2014)In the present study, chromium, cadmium and metal mixed (chromium + cadmium) removal and its association with exopolysaccharides and uronic acids production in Synechocystis sp. BAS0671 were investigated. It was investigated ... -
pH responsive itaconic acid grafted alginate microspheres for the controlled release of nifedipine
(Elsevier Sci Ltd, 2011)A series of pH responsive alginate-g-poly(itaconic acid) (NaAlg-g-PIA) microspheres were prepared as drug delivery matrices of nifedipine cross-linked by glutaraldehyde (GA) in the hydrochloric acid catalyst. Graft copolymers ... -
Preparation of reversibly immobilized lysozyme onto Procion Green H-E4BD-attached poly(hydroxyethylmethacrylate) film for hydrolysis of bacterial cells
(Elsevier Sci Ltd, 2001)The flat sheet support for enzyme immobilization was prepared by UV-initiated photopolymerization of 2-hydroxyethyl-methacrylate (HEMA) in the presence of an initiator (alpha alpha'-azoisobutyronitrile. AIBN). An affinity ... -
Reversible immobilization of lipase on phenylalanine containing hydrogel membranes
(Elsevier Sci Ltd, 2001)Poly(2-hydroxyethylmethacrylate-co-methacrylamidophenlyalanine) poly(HEMA-MAPA) membranes were prepared by UV-initiated photopolymerization of HEMA and MAPA. Lipase immobilization onto these membranes from aqueous solutions ... -
Reversible immobilization of urease onto Procion Brown MX-5BR-Ni(II) attached polyamide hollow-fibre membranes
(Elsevier Sci Ltd, 2002)Urease was immobilized onto Procion Brown MX-5BR attached and Ni(II) incorporated microporous polyarnide hollow-fibre membrane via adsorption. Urease immobilization onto the polyamide hollow-fibre membrane from aqueous ... -
Silver and fluoride doped hydroxyapatites: Investigation by microstructure, mechanical and antibacterial properties
(Elsevier Sci Ltd, 2013)Hydroxyapatite co-doped with Ag+ and F- ions was synthesized by the precipitation method and sintered at 1100 degrees C for 1 h. Samples were characterized by density, X-ray diffraction, Fourier transform infrared spectroscopy, ... -
Synthesis and mechanical properties of interpenetrating networks of polyhydroxybutyrate-co-hydroxyvalerate and polyhydroxyethyl methacrylate
(Elsevier Sci Ltd, 1998)Naturally occurring, biocompatible, and biodegradable polyhydroxybutyrate-co-hydroxyvalerate (PHBV), and synthetic, non-degrading polyhydroxyethylmethacrylate (PHEMA) membranes were prepared and their mechanical properties ... -
Thermal behaviour of alumina precursor obtained by the aluminium sulphate-urea reaction in boiling aqueous solution
(Elsevier Sci Ltd, 2003)An aqueous solution containing 0.1 M Al3+ and excess urea was boiled for 4 h to obtain an alumina precursor precipitate. The precursor precipitate was separated into several portions and each portion was heated at a different ...
