Capillary electrophoresis in metabolomics
(Elsevier Sci Ltd, 2006)
This article describes the potential of capillary electrophoresis (CE) in metabolomics, which concerns the comprehensive analysis of endogenous low-molecular weight compounds in a biological system. Consequently, metabolomic ...
Functionalization of low molecular weight atactic polypropylene - Part II. Thermal and molecular weight studies
(Springer, 2000)
Number average molecular weight (M-n), intrinsic viscosity ([eta]) and glass transition temperature (T-g) of low molecular weight atactic polypropylene (APP) grafted with 4-allyl-1,2-dimethoxybenzene (DMAB), 4-allyl-2-me ...
Preparation of ion-exchange beads based on poly (methacrylic acid) brush grafted chitosan beads: Isolation of lysozyme from egg white in batch system
(Elsevier Science Bv, 2007)
Poly(methacrylic acid) brush grafted crosslinked-chitosan (chitosan-g-poly(MAA)) beads were prepared in two sequential steps: in the first step, chitosan beads were prepared by phase-inversion technique and then were ...
Synthesis and characterization of poly(N-Vinyl-2-pyrrolidone) grafted sodium alginate hydrogel beads for the controlled release of indomethacin
(Wiley, 2008)
Graft copolymers of sodium alginate (NaAlg) with N-vinyl-2-pyrrolidone were prepared using azobisisobutyronitrile as initiator. The graft copolymers (NaAlg-g-PVP) were characterized with Fourier transform infrared spectroscopy, ...
Novel hydrophobic ligand-containing hydrogel membrane matrix: preparation and application to gamma-globulins adsorption
(Elsevier Science Bv, 2001)
In this study, phenylalanine as a hydrophobic ligand was covalently attached to the co-monomer methacrylochloride. Then, poly(2-hydroxyethylmethacrylate-co-methacrylamidophenyalanine) [poly(HEMA-MApA)] membranes were ...
Studies of adsorption of alkaline trypsin by poly(methacrylic acid) brushes on chitosan membranes
(John Wiley & Sons Inc, 2008)
Poly(methacrylic acid)-grafted chitosan membranes (chito an-g-poly(MAA)) were prepared in two sequential steps: in the first step, chitosan membranes were prepared by phase-inversion technique and then epichlorohydrin was ...
DNA adsorption on a poly-L-lysine-immobilized poly(2-hydroxyethyl methacrylate) membrane
(Wiley, 2003)
The DNA adsorption properties of poly-L-lysine-immobilized poly(2-hydroxyethyl methacrylate) (pHEMA) membrane were investigated. The pHEMA membrane was prepared by UV-initiated photopolymerization and activated with ...
Kinetics of mercury ions removal from synthetic aqueous solutions using by novel magnetic p(GMA-MMA-EGDMA) beads
(Elsevier, 2007)
Poly(glycidylmethacrylate-methylmethacrylate), p(GMA-MMA-EGDMA), magnetic beads were prepared via suspension polymerization in the presence of ferric ions. The epoxy groups of the beads were converted into amino groups via ...
Synthesis, Physical Properties, and Application of Aminated Poly(glycidyl methacrylate)/Zeolite Composite
(Wiley, 2016)
Poly(glycidyl methacrylate)/zeolite (PGMA/Z) composite was prepared by free radical polymerization and it was further modified to contain amino groups on its surface, by reacting to hexamethylenediamine. FTIR, TG, and SEM ...
On Multivariate Bleimann, Butzer and Hahn Operators
(SPRINGER BASEL AG, 2020)
In this paper, we state a Korovkin-type theorem for uniform approximation of functions, belonging to a class generated by multivariable function of modulus of continuity, by the sequence of multivariate positive linear ...
