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)
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. ...
Film formation from TiO2-polystyrene latex composite: a fluorescence study
(Taylor & Francis Group, 2007)
This work reports the use of the steady state fluorescence (SSF) technique for studying film formation from TiO2 covered polystyrene (PS) latex particles. The composite films were prepared from pyrene (P)-labeled PS particles ...
Film formation from pure and mixed latices; transient fluorescence study
(Academic press inc Elsevier science, 2005-11-15)
A fast transient fluorescence technique was used to study latex film formation induced by organic solvent vapor. Mixtures of pyrene (P)- and naphthalene (N)-labeled and/or pure naphthalene-labeled latex films were prepared ...
Film formation from PS latex doped PNIPAM hydrogels at various heating and cooling rates
(VSP BV, BRILL ACADEMIC PUBLISHERS, 2008)
Film formation from polystrene (PS) latex doped poly(N-isopropylacrylamide) (PNIPAM) hydrogels was studied by using photon transmission technique. The transmitted light intensity, It, was monitored during film formation ...
Small molecule desorption from a swelling polymeric glass in polymer solution: Energy transfer method
(Elsevier Science Sa, 2005-07)
Direct energy transfer (DET) method conjunction with fast transient fluorescence (FTRF) technique were used to study small molecule desorption from a swelling poly(methyl methacrylate) (PMMA) glass in polymer solution, ...
Time evolution of film formation from polystyrene particles: a percolation approach
This work reports the film formation process from surfactant-free polystyrene (PS) latex particles. Steady state fluorescence and photon transmission techniques were used to study the evolution of film formation. The films ...
Small molecule desorption prior to dissolution of a polymeric glass
(Wiley Subscription Services, Inc., A Wiley Company, 2006-07-15)
Poly(methyl methacrylate) (PMMA) discs in various molecular weights (M-w) were prepared by free-radical polymerization. Pyrene (Py) was introduced during polymerization as a fluorescence probe. In situ steady state ...
Monitoring diffusion of reptating polymer chains by a direct energy transfer method: A Monte Carlo simulation
A kinetic Monte Carlo method was used to simulate the diffusion of reptating polymer chains across an interface. A time-resolved fluorescence technique in conjunction with a direct energy transfer method was used to measure ...
