Poly (styrene) latex/modified na-activated bentonite nanocomposite films: a fluorescence study
(ELSEVIER SCIENCE BV., 2008-12)
We studied film formation of composites of surfactant-free polystyrene (PS) nanoparticles and modified Na-activated bentonite (MLB), by steady state fluorescence (SSF) technique. The films were prepared from a mixture of ...
Reordering of polystyrene gel due to multiple swelling in organic vapor- Fast transient fluorescence technique study
(Elsevier science sa, 2006-07-31)
Reordering of disc-shaped polystyrene (PS) gels due to multiple swelling, under organic vapor was studied by using Fast Transient Fluorescence (FTRF) technique. Disc-sbaped polystyrene gels were prepared by free radical ...
Molecular alignment during gel formation from methyl methacrylate: An excimer fluorescence study
(Taylor & Francis Ltd, 2005-05)
Glass transition during bulk polymerization was studied in free-radical cross-linking copolymerization (FCC) of methyl methacrylate (MMA) using the steady-state fluorescence (SSF) technique. Naphthalene (N) was used as a ...
Monitoring small molecule diffusion into hydrogels at various temperatures by fluorescence technique
(Elsevier B.V, 2006-12-01)
steady state fluorescence technique was used to study small molecule diffusion into polyacrylamide (PAAm) gels at various temperatures. Pyranine (P-y), dissolved in water was introduced as a probe and fluorescence emission ...
In situ fluorescence study of swelling, sorption and desorption processes in and out of PAAm gels
(WILEY-V C H VERLAG GMBH, 2008)
Small molecule sorption and desorption in and out of polyacrylamide (PAAm) gels were studied at various temperatures. Pyranine (P(y)) dissolved in water used as a probe. Fluorescence emission intensity, I(p) from P(y) was ...
Small molecule sorption and desorption in and out of PAAm hydrogels at various temperatures
(PROUS SCIENCE, SA, 2007-07)
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 ...
Photon transmission study on conformational ordering of iota-carrageenan in CaCl2 solution
(Adenine Press, 2005-06)
Coil-to-double helix (c-h) and double helix-to-dimer (h-d) phase transitions of iota-carrageenan in CaCl2 solution upon cooling were studied using photon transmission technique. Photon transmission intensity, I-iota r was ...
Ceramic encapsulated latex composites
(Elsevier Inc, 2006-04-15)
This work reports the encapsulation of latex particles in Al(2)O(3)-polystyrene (PS) composite films. These films were prepared from PS particles in Al(2)O(3) dispersion at room temperature in various latex contents. ...
Slow release from carrageenan gels at various temperatures
