Preparation and characterization of sulfonyl-hydrazine attached poly(styrene-divinylbenzene) beads for separation of albumin
(Elsevier Science Bv, 2007)
Novel sulfonyl-hydrazine carrying poly(styrene-divinylbenzene), poly(S-DVB)-S-NH2 ion-exchange beads (size between 210 and 425 mu m) were prepared via suspension polymerization and, were first used as an ion-exchange support ...
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, ...
A model for initial-stage sintering thermodynamics of an alumina powder
(Elsevier Science Sa, 2008)
A model was proposed to calculate several thermodynamic parameters for the initial-stage sintering of an alumina powder obtained after calcinations at 900 degrees C for 2 h of a precursor. The precursor was synthesized by ...
Use of methacrylic acid grafted poly(ethylene terephthalate) fibers for the removal of basic dyes from aqueous solutions
(John Wiley & Sons Inc, 2008)
A reactive fibrous adsorbent was prepared through the grafting of a methacrylic acid monomer Onto poly(ethylene terephthalate) fibers for the removal of basic dyes such as methylene blue and basic red 9 from aqueous solutions ...
Chitosan-grafted poly(hydroxyethyl methacrylate-co-glycidyl methacrylate) membranes for reversible enzyme immobilization
(Wiley, 2007)
Epoxy group-contain g poly(hydroxyethyl methacrylate/glycidyl methacrylate), p(HEMA/GMA), membrane was prepared by UV initiated photopolymerization. The membrane was grafted with chitosan (CH) and some of them were chelated ...
Female sexual and hormonal status in patients with bronchial asthma: Relationship with respiratory function tests and psychological and somatic status
(Elsevier Science Inc, 2007)
OBJECTIVES To assess the relationship among the sexual, hormonal, physical, and psychological status of women with bronchial asthma (BA) compared with that of healthy volunteers. METHODS Thirty-eight women with BA were ...
Thermal properties and crystallinity of thermotropic liquid crystalline copolyesters prepared from poly(ethylene terephtalate) (PET) and rigid aromatic units
(Taylor & Francis Inc, 2007)
A series of copolyesters were synthesized by rnelt-polycondensation reaction of poly(ethylene terephtalate) (PET) with various proportions of equimolar compositions of p-acetoxybenzoic acid (p-ABA), hydroquinone diacetate ...
