Polymers from renewable resources: synthesis and characterization of poly(2,5-dihydro-2,5-dimethoxy furan)
(Scientific Technical Research Council Turkey-Tubitak, 2012)
The cationic polymerization of cis, trans-2,5-dihydro-2,5-dimethoxy furan (DHMF) was studied in the presence of HClO4, in acetonitrile. Different reaction parameters were investigated such as initiator concentration and ...
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 ...
Polyaniline micro-rods based heterojunction solar cell: Structural and photovoltaic properties
(Amer Inst Physics, 2012)
The present paper reports the fabrication and photovoltaic characterization of pure and dodecyl benzene sulfonic acid (DBSA)-doped polyaniline (PAni) micro-rods polymer/n-Si heterojunction solar cells, and also the ...
