Efficient Removal of Acidic Dye Using Low-Cost Biocomposite Beads
(Amer Chemical Soc, 2013)
The objective of this study is to prepare and characterize chitosan/zeolite biocomposite beads and utilize them as adsorbent for removal of anionic dye, Acid Black 194 (AB194). Characterization studies of biocomposite beads ...
Non-Acidic Mediated Friedel-Craft Reaction of Thiophene Using EtAlCl2
(Asian Journal Of Chemistry, 2013)
Since alkyl Lewis acids are Bronsted bases, they give a non-acidic reaction media. In this context, acylation of thiophene is investigated in the presence of EtAlCl2 and non-acidic media. Besides 8 examples of thiophene, ...
Covalent immobilization of Candida rugosa lipase on aldehyde functionalized hydrophobic support and the application for synthesis of oleic acid ester
(Taylor & Francis Ltd, 2013)
This study focuses on Candida rugosa lipase (CRL) immobilization by covalent attachment on poly(ethylene terephthalate)-grafted glycidyl methacrylate (PET-g-GMA) fiber. The immobilization yielded a protein loading of ...
Fabrication and characterization of gold-nanoparticles/chitosan film: a scaffold for L929-fibroblasts
(Taylor & Francis Ltd, 2013)
The objective of the present study was to fabricate a gold nanoparticle crosslinked chitosan (Ch/AuNPs) composite film simple and to evaluate its use as a carrier matrix for L929-fibroblasts. L929-fibroblasts were seeded ...
Preconcentration and electroanalysis of silver at pt electrode modified with poly(2-aminothiazole)
(Maik Nauka/Interperiodica/Springer, 2013)
Conducting poly(2-aminothiazole) (PAT) films were electrodeposited on a platinum disc electrode surface by constant potential electrolysis of 2-aminothiazole (AT) for the stripping voltammetric determination of Ag(I). Ag(I) ...
Statistical Classification of Cigarettes Using High Pressure Liquid Chromatograms of Cigarette Filter Tar as Fingerprint
(Asian Journal Of Chemistry, 2013)
In this work, we have showed that a liquid chromatogram can be used as finger print to characterize and classify cigarettes. A liquid chromatographic (high pressure liquid chromatography) procedure was first developed to ...
An indirect thermodynamic model developed for initial stage sintering of an alumina compacts by using porosity measurements
(Springer, 2012)
The specific micro- and mesopore volumes (V) of alumina compacts fired between 900 and 1250 A degrees C for 2 h were determined from nitrogen adsorption/desorption data. The V value was taken as a sintering equilibrium ...
Improvement of Bioethanol Productivity of Immobilized Saccharomyces Bayanus with Using Sodium Alginate-Graft-Poly(N-Vinyl-2-Pyrrolidone) Matrix
(Springer, 2012)
In this study, immobilization conditions and bioethanol production characteristics of immobilized Saccharomyces bayanus were investigated into sodium alginate-graft-poly(N-vinyl-2-pyrrolidone; NaAlg-g-PVP) matrix. The ...
Investigation on selective adsorption of Hg(II) ions using 4-vinyl pyridine grafted poly(ethylene terephthalate) fiber
(Wiley, 2012)
In the work, poly(ethylene terephthalate) (PET) fibers were grafted with 4-vinyl pyridine (4-VP) monomer using benzoyl peroxide (Bz(2)O(2)) as initiator in aqueous media. The removal of Hg(II) ions from aqueous solution ...
Immobilization of laccase on polyacrylamide and polyacrylamide – κ – carragennan-based semiinterpenetrating polymer networks
(Informa Healthcare, 2012)
In this study, laccase enzyme (L) from Agaricus bisporus was immobilized by entrapment into polyacrylamide (PAAm) and semi-interpenetrating polymer networks (semi-IPNs) prepared with either polyacrylamide/kappa-carragennan ...
