Chitosan based metal-chelated copolymer nanoparticles: Laccase immobilization and phenol degradation studies
(Elsevier Sci Ltd, 2017)
Immobilization improves the stability and reusability of enzymes. In this study, laccase, which is a green biocatalyst, was immobilized onto Cu (II)-chelated chitosan nanoparticles via adsorption and successfully applied ...
Colorimetric Bisphenol-A Detection With a Portable Smartphone-Based Spectrometer
(Ieee-Inst Electrical Electronics Engineers Inc, 2018)
Water quality monitoring in resource-limited settings without access to a sophisticated laboratory requires the development of low cost and portable instrumentation. Herein, we propose a newly designed handheld reflection-based ...
Preparation of nanofibrous polymer grafted magnetic poly(GMA-MMA)-g-MAA beads for immobilization of trypsin via adsorption
(Elsevier, 2008)
Poly (glycidylmethacrylate-methylmethacrylate), poly(GMA-MMA) beads were prepared via suspension polymerization in the presence of ferric ions. The epoxy groups of the poly(GMA-MMA) beads were converted into amino groups ...
Synthesis and Characterization of Chitosan/Polyvinylpyrrolidone/Zeolite Composite by Solution Blending Method
(Springer, 2014)
Polymer/clay composites have been studied for several decades; in the study, polymer/zeolite composite beads have been prepared by a simple solution blending method using chitosan, polyvinylpyrrolidone and zeolite particles ...
Increasing the crystallite and conductivity of polypyrrole with dopant used
(Springer Heidelberg, 2014)
The chemical polymerization method is very convenient for obtaining a plurality of the polymer. Chemical synthesizes of polypyrrole (PPy) were performed in acetonitrile solutions containing different dopants: dodecylbenzene ...
Tetrakis(μ3-phenoxo-acetonitrilelithium), a tetrameric lithium aryloxide with a cubane core
(Int Union Crystallography, 2003)
The title compound, (CH3CNLiOC6H5)(4) or [Li-4 (C6H5O)(4) (C2H3N)(4)], is tetrameric with a distorted Li4O4 cube core. The molecule has crystallographic (4) over bar symmetry. Each Li atom has distorted tetrahedral ...
Poly[μ-aqua-aqua-μ-3-carboxypyrazine-2-carboxylato-sodium(I)]
(Int Union Crystallography, 2006)
The crystal structure of the title compound, [Na(C6H3N2O4)(H2O)(2)](n), consists of molecular ribbons containing octahedral NaO5N units. Two adjacent Na atoms are bridged by two water molecules to give a centrosymmetric ...
ICG-Conjugated magnetic graphene oxide for dual photothermal and photodynamic therapy
(Royal Soc Chemistry, 2016)
Aptamer-functionalized magnetic graphene oxide conjugates loaded with indocyanine green (ICG) dye, or Apt@ICG@mGO, have been successfully developed for dual-targeted photothermal and photodynamic therapy. In general, a ...
Adsorption of trypsin onto magnetic ion-exchange beads of poly(glycidylmethacrylate-co-ethyleneglycoldimethacrylate)
(John Wiley & Sons Inc, 2008)
Magnetic beads were prepared from glycidyl methacrylate (GMA), and ethyleneglycol dimethylmethacrylate (EGDMA) in the presence of Fe3O4 nanopowder via suspension polymerization. The magnetic beads were characterized by ...
Removal of Cd(II), Hg(II), and MID ions from aqueous solution using p(HEMA/Chitosan) membranes
(Wiley, 2007)
An interpenetration network (IPN) was synthesized from 2-hydroxyethyl methacrylate (HEMA) and chitosan, p(HEMA/chitosan) via UV-initiated photo-polymerization. The selectivity to different heavy metal ions viz Cd(II), ...
