Study of Film Formation From PS Latex/TiO2 NanocompositesEffect of Latex Size and TiO2 Content
(Wiley-Blackwell, 2014)
In this work we investigated the film formation from polystyrene (PS) latex/TiO2 nanocomposites using the steady state fluorescence (SSF) and UV-vis (UVV) techniques depending on PS particle size and TiO2 content. The ...
Universality of elasticity on PAAM-NIPA copolymer gels
(EDP Sciences, 2015)
Polyacrylamide (PAAm)-N-isopropylacrylamide (NIPA) copolymers were prepared via free radical crosslinking copolymerization with different molar of NIPA varying in the range between 0 and 2 M. The mechanical properties of ...
Cation Effect on Slow Release from Alginate Beads: A Fluorescence Study
(Springer/Plenum Publishers, 2014)
In this study spherical alginate beads containing pyranine (P-y) as a fluorescence probe were prepared by ionotropic gelation of a sodium alginate solution. The steady state fluorescence technique was used to study pyranine ...
A mathematical characterization of the gel point in sol-gel transition
(IOP Publishing Ltd, 2015)
We model the sol-gel transition in terms of Susceptible-Infected-Removed (SIR) and Susceptible-Exposed-Infected-Removed (SEIR) models and compare with experimental results. We show, numerically, that the "gel point" described ...
Graphene oxide-polyacrylamide composites: Optical and mechanical characterizations
(Wiley Blackwell, 2019)
Graphene oxide (GO) is a two-dimensional carbon material with similar one-atom thickness, and is a light material having extremely high strength and thermal stability [1]. Thus, GO is an efficient filler for the enhancement ...
