Sodium carboxymethyl cellulose was converted into microspheres by crosslinking with aluminum chloride. Various microsheres with different amounts of crosslinker, biopolymer of various concentrations and molecular weights, and with different pesticide (Aldicarb) contents and pesticide to polymer ratios were prepared. The pesticide encapsulation efficiencies and aldicarb release kinetics of the resultant microcapsules were investigated. It was possible to modify the release behaviour by varying the above parameters and to have drug release with half-lives longer than 100 hours in aqueous media. The release kinetics were described by first order and zero order kinetics.

ELECTROLYSIS OF MGCL2 WITH A TOP INSERTED ANODE AND AN MG PB CATHODE GUDEN, M; Karakaya, İshak (Springer Science and Business Media LLC, 1994-08-01) High energy consumption in the production of magnesium by molten salt electrolysis is mainly due to the recombination of magnesium and chlorine. The large interelectrode distance used, in conventional techniques, to reduce the extent of 'back reaction', results in a significant potential drop. A laboratory cell that enables the operation with smaller interelectrode distance and easy separation of electrode products has been used to study electrolytic magnesium production. The cell features a top inserted gr...
Controlled release of vancomycin from biodegradable microcapsules Ozalp, Y; Ozdemir, N; Kocagoz, S; Hasırcı, Vasıf Nejat (2001-01-01) Poly D,L-lactic acid (PLA) and its copolymers with glycolide PLGA 90:10 and 70:30 were polymerized under various conditions to yield polymers in the molecular weight range 12 000-40 000 daltons, as determined by gel permeation chromatography. Vancomycin hydrochloride was the hydrophilic drug of choice for the treatment of methicillin resistant Staphyloccoccal infections. It was microencapsulated in the synthesized polymers using water-oil-water (w/o/w) double emulsion and solvent evaporation. The influence ...
Kinetic investigation of chemical vapor deposition of B4C on tungsten substrate Karaman, Mustafa; Sezgi, Naime Aslı; Doğu, Timur; Ozbelge, H. Onder (2006-12-01) Production of beta-rhombohedral boron carbide (B4C) on a tungsten substrate by the chemical vapor deposition from a BCl3-H-2-CH4 gas mixture was achieved. An impinging-jet reactor was used to minimize the mass-transfer limitations on the reaction kinetics, which made a detailed kinetic investigation possible. Results of the XRD and XPS analyses showed that the solid product formed on the substrate is a rhombohedral B4C phase. Both dichloroborane and boron carbide formation rates were found to increase with ...
Selective mercury uptake by polymer supported hydroxyethyl sulfonamides Oktar, Ceren; Yılmaz, Levent; Ozbelge, H. Onder; Bicak, Niyazi (Elsevier BV, 2008-04-01) Hydroxyethyl sulfonamide function supported on styrene-divinyl benzene (9% mol/mol) bead resin is presented as mercury selective reagent. The resin product with 3.49 mmol g(-1) of 2-hydroxyethyl sulfonamide content removes reasonable quantities of mercuric ions (0.83-1.64 mmol g(-1)) from aqueous solutions of HgCl2, Hg (CH3COO)(2) and Hg (NO3)(2), in non-buffered conditions. Experiments showed that, the resin is able to extract mercury selectively, in the presence of foreign ions such as Zn(II), Cd(II), Fe(...
Uptake of Divalent Ions (Mn+2 and Ca+2) by Heat-Set Whey Protein Gels Öztop, Halil Mecit; MCCARTHY, Michael J.; ROSENBERG, Moshe (2012-02-01) Divalent salts are used commonly for gelation of polymer molecules. Calcium, Ca+2, is one of the most common divalent ions that is used in whey protein gels. Manganese, Mn+2, is also divalent, but paramagnetic, enhancing relaxation decay rates in magnetic resonance imaging (MRI) and can be used as a probe to understand the behavior of Ca+2 in whey protein gels. The objective of this study was to investigate the diffusion of Ca+2 and Mn+2 ions in heat-set whey protein gels by using MRI and nuclear magnetic r...
