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 ...
Molecular recognition during sol-gel and gel-sol transition of kappa-iota carrageenan mixtures
(Taylor & Francis ltd, 2005-12)
Sol-gel and gel-sol phase transitions of kappa-iota (kappa-iota) carrageenan mixtures in two types of salts were studied using photon transmission technique. Here, KCl and CaCl2 were chosen as the proper salts for the ...
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 ...
Film formation from nano-sized polystrene latex covered with various TiO2 layers
(Wiley Subscription Services, Inc., A Wiley Company, 2006-12)
Steady-state fluorescence technique was used for studying film formation from TiO2 covered nano-sized polystyrene latex particles. The composite films were prepared from pyrene (P)-labeled PS particles by covering them ...
Fluorescence study on Al2O3-polystyrene latex composite film formation
(John Wiley & Sons Inc, 2005-06)
This work reports a steady state fluorescence (SSF) technique for studying film formation from mixture of Al2O3 and polystyrene (PS) latex particles. The composite films were prepared from dispersion of pyrene (P)labeled ...
Slow release from carrageenan gels at various temperatures
(PROUS SCIENCE, SA, 2007-07)
Cation effect on gel-sol transition of kappa carrageenan
The steady state fluorescence (SSF) technique was employed to study gel - sol transitions of kappa carrageenan in NaCl, KCl and CaCl2 solutions. Pyranine was used as a fluorescence probe for monitoring these transitions. ...
Vapor-induced film formation from low-T-g particles for different solvent compositions
(Elsevier Inc, 2006-05-15)
The photon transmission method was used to study latex film formation from poly(vinyl acetate) (PVAc) particles induced by two different solvents. Films with the same latex content were prepared from PVAc particles and ...
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 diffusion into swelling Iota-Carrageenan gels: A fluorescence study
(Taylor & Francis Group, 2007-04)
Small molecule diffusion into Iota-Carrageenan gel was studied by using steady-state fluorescence (SSF) technique. Pyranine, dissolved in water was used as fluorescence probe. Fluorescence emission intensity, I-p, and ...
