Production of 2-hydroxyethyl methacrylate-g-poly(ethylene terephthalate) nanofibers by electrospinning and evaluation of the properties of the obtained nanofibers
(WILEY, 2020)
Nanofiber production was investigated from poly(ethylene terephthalate) (PET) polymers functionalized with hydroxyethyl methacrylate (HEMA) by grafting of HEMA monomers onto the PET fibers. HEMA grafted PET (PET-g-HEMA) ...
Synthesis and characterization of poly(ethylene terephthalate) fibers grafted with N-(hydroxymethyl) acrylamide by free radical: its application in elimination of Congo red
(SPRINGER, 2020)
In this study, firstly, N-(hydroxymethyl) acrylamide (HMAAm) was grafted on poly(ethylene terephthalate) fibers (PET) by utilizing benzoyl peroxide (Bz(2)O(2)) as an initiator. The alteration in graft percentage with the ...
Microwave-assisted synthesis of alginate-g-polyvinylpyrrolidone copolymer and its application in controlled drug release
(Springer, 2014)
The aim of this study is to synthesize graft copolymer (NaAlg-g-PVP) in microwave oven and prepare pH-responsive beads with high entrapment efficiency. For this purpose, PVP was grafted onto sodium alginate using microwave ...
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 Saccharomyces cerevisiae on to modified carboxymethylcellulose for production of ethanol
(Springer, 2011)
In this work, modified carboxymethylcellulose (CMC) was used as a new support material for production of ethanol. Crosslinked graft copolymers of CMC with N-vinyl-2-pyrrolidone (N-VP) were prepared in different grafting ...
Production of bioethanol by immobilized Saccharomyces Cerevisiae onto modified sodium alginate gel
(Wiley-Blackwell, 2011)
BACKGROUND: Microbial bioethanol production is an important option in view of the finite global oil reserves. Bioethanol fermentation was carried out using immobilized microorganisms (Saccharomyces cerevisiae, Zymomonas ...
Controlled release of indomethacin from crosslinked alginate beads
(Walter De Gruyter Gmbh, 2008)
Beads of the sodium alginate ( NaAlg) were prepared by dropping aqueous sodium alginate ( NaAlg) into glutaraldehyde ( GA) as a crosslinker and HCl as a catalyst mixture solution. Beads prepared were used to deliver a model ...
Use of 4-vinylpyridine and 2-hydroxyethylmethacrylate monomer mixture grafted poly(ethylene terephthalate) fibers for removal of congo red from aqueous solution
(Walter De Gruyter Gmbh, 2008)
In this study, a novel fibrous adsorbent made by grafting 4-vinyl pyridine (4-VP) and 2-hydroxyethylmethacrylate (HEMA) monomer mixture onto poly(ethylene terephthalate) (PET) fibers was used for removal of Congo red (CR) ...
Adsorption behavior of congo red from an aqueous solution on 4-vinyl pyridine grafted poly(ethylene terephthalate) fibers
(John Wiley & Sons Inc, 2008)
In this study, a reactive fibrous adsorbent was prepared through the grafting of 4-vinyl pyridine monomer onto poly(ethylene terephthalate) (PET) fibers for the removal of Congo red (CR) dye from an aqueous solution with ...
