Determination of pre-gelation and post-gelation activation energies during free radical crosslinking copolymerization
(Taylor & Francis Ltd, 2005)
Steady-state fluorescence (SSF) and dilatoraetric techniques were used to study the free-radical crosslinking copolymerization (FCC) of styrene (S) and divinylbenzene (DVB) in bulk. The gel points (t g) were recorded by ...
Dissolution of Al2O3-polystyrene latex composites: A fluorescence study
(Taylor & Francis Ltd, 2005)
This work reports the use of the steady state fluorescence (SSF) technique to study dissolution of a composite film formed from a mixture of Al 2O3 and polystyrene (PS) latex particles. The composite films were cast from ...
Reversible film formation from PS doped PNIPAM particles in various compositions
(John Wiley & Sons Inc, 2008-02)
Film formation from polystyrene (PS) doped poly(N-isopropylacrylamide) (PNIPAM) particles was studied using photon transmission technique. The transmitted light intensity, Itr, was monitored during film formation process. ...
Structure and expression analyses of the Fertilization Independent Seed (FIS) gene orthologs of the apomict Boechera species
(Society for Biology and Biotechnology, 2015)
In this study Arabidopsis thaliana Fertilization Independent Seed 2 (FIS2) and Fertilization Independent Endosperm (FIE) genes orthologs were analysed in pseudogamous apomict and sexual Boechera species. FIS genes encode ...
New quartz technique for OSL dating of limestones
(2010)
The equivalent dose De determination of limestone-made ancient constructions by thermoluminescence (TL) prevents accurate measurements and requires plateau test of bleached curves. Optical stimulated luminescence (OSL) of ...
Critical behavior of thermal phase transitions of iota-carrageenan in CaCl2 solution
(Elsevier B.V., 2006-07-15)
In situ photon transmission method was applied to study thermal phase transitions of ?-carrageenan in CaCl2 solution. Coil-to-helix (c-h) and helix-to-dimer (h-d) transitions were detected upon cooling. An extra dimer-to-dimer ...
The statistics of energy states of a Hookean model for proteins
(TÜBİTAK, 2000)
A generic model of a random polypeptide chain, with discrete torsional degrees of freedom and Hookean springs connecting pairs of hydrophobia residues, reproduces the energy probability distribution of real proteins over ...
Comparision of critical parameters of polymerization and gelation processes: A fast transient fluorescence study
(World Scientific Publ Co Pte Ltd, 2005-03-10)
The fast transient fluorescence technique was used to study free-radical polymerization and crosslinking copolymerization of styrene. Ethylene glycol dimethacrylate and Pyrene were used as crosslinking agent and fluorescence ...
Synthesis and liquid crystalline behavior of random copolymer of poly(ethylene oxide) macromonomer and liquid crystalline monomer by the photon transmission technique
(Taylor & Francis Inc, 2005-12)
Random copolymers of poly(ethylene oxide) macromonomer with p-vinylbenzyl end-functional group (PEOVB) and liquid crystalline monomer, namely 6-(4-cyanobiphenyl-4'-oxy)hexyl acrylate (COA), were prepared by conventional ...
The liquid–glass transition – is it a fourth order phase transition?
(Elsevier Science, 2005-09-01)
The liquid-glass transition is analyzed using a theory of Brownian motion in liquids recently developed by the author. It is shown that if a liquid could be cooled in quasi-static process and still avoids crystallization ...
