Film formation from TiO2-polystyrene latex composite: a fluorescence study
(Taylor & Francis Group, 2007-03-01)
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 ...
Monovalent and divalent cation effects on phase transitions of iota-carrageenan
(Sage Publications Ltd, 2007-01)
Phase transitions Of L-carrageenan in a variety of monovalent (Li, Na, K) and divalent (Mg, Ca, Sr) cation solutions were studied during heating and cooling by using photon transmission technique. Photon transmission ...
A photon transmission study for film formation from poly(vinyl acetate) latex particles with different molecular weights
(John Wiley & Sons Inc, 2007-10-15)
The photon transmission technique was used to monitor the temperature evolution of film formation from poly(vinyl acetate) (PVAc) latex particles with two different molecular weights. Two sets of latex films were prepared ...
