Study on critical behaviour in N-isopropyl acrylamide gels by using fluorescence technique
(Taylor & Francis Group, 2006-11)
The steady state fluorescence (SSF) technique was used to study the sol-gel transition for the solution free radical crosslinking copolymerization of N-isopropyl acrylamide (NIPA), with N,N'-methylenebis (acrylamide) (BIS) ...
Effects of annealing on morphology of polymer/polymer (PS/PMMA) blend; a fluorescence study
(John Wiley& Sons Inc, 2006-05-05)
Steady state fluorescence (SSF) technique conjunction with optical microscopy were used to study the morphology of polystyrene (PS)/poly(methyl methacrylate) (PMMA) blend upon annealing above glass transition in elevated ...
Electrochromic switching of WO3 nanostructures and thin films
(Springer-Verlag, 2006-04)
We present transmission measurements through tungsten tri-oxide nanostructures and thin films prepared by sol-gel process on micro-contact printed substrates. Identical electrochromic switching times are found for both the ...
Electron-phonon mass enhancement parameter of the (Gamma) over-bar surface state on Au(111) measured by photoemission spectroscopy
(American Physical Society, 2006-07)
We report the measurement of lambda, the electron-phonon mass enhancement parameter, for the spin-orbit-split Gamma surface state on Au(111). lambda is determined from the change of the photoemission linewidth as a function ...
Theory of fluidity of liquids, glass transition, and melting
(Elsevier B.V., 2006-03-01)
This is a presentation of a rigorous theory of fluidity of liquids, glass transition and melting of solids in the frame of an asymmetric double well potential model. Potential wells are doubled time to time by the local ...
Film formation stages for poly(vinyl acetate) latex particles: a photon transmission study
(Springer-Verlag, 2006-07)
Photon transmission technique was used to monitor the evolution of transparency during film formation from poly(vinyl acetate) (PVAc) latex particles. The latex films were prepared below the glass transition temperature ...
Reversible film formation from nano-sized PNIPAM particles below glass transition
(Springer-Verlag, 2007-01)
Reversible film formation process from nano-sized Poly(N-isopropylacrylamide) (PNIPAM) microgel particles were studied during heating-cooling cycles at various rates. Photon transmission technique was used and transmitted ...
Drying of PAAm hydrogels at various temperatures: A fluorescence study
(Taylor & Francis Group, 2007-05)
The steady-state fluorescence (SSF) technique was employed for studying the drying of polyacrylamide (PAAm) hydrogels. Disc-shaped hydrogels were prepared by free-radical crosslinking copolymerization of acrylamide (AAm) ...
Study on swelling of hydrogels (PAAm) at various temperatures by using fluorescence technique
(Springer US, 2007-10)
Steady-state fluorescence (SSF) technique was employed for studying swelling of polyacrylamide (PAAm) hydrogels. Disc-shaped gels were prepared by free-radical crosslinking copolymerization of acrylamide (AAm) with N, N'- ...
Small molecule sorption and desorption in and out of iota-carrageenan gels
(Taylor & Francis Group, 2007-08)
Small molecule sorption and desorption in and out of Iota-Carrageenan was studied by using steady-state fluorescence (SSF) technique. Pyranine dissolved in water used as fluorescence probe. Fluorescence emission intensity, ...
