Thermal Phase Transitions of IOTA Carrageenan in CaCl2 Solutions: A Fluorescence Study
(Taylor & Francis Inc, 2011)
The fluorescence technique was employed to study thermal phase transitions of iota (-) carrageenan (IC) in CaCl2 solution. IC gels underwent coil to double helix (c-h) and double helix to dimer (h-d) transitions upon ...
Modelling of Swelling by the Fluorescence Technique in Kappa Carrageenan Gels
(Amer Inst Physics, 2011)
Kappa (-kappa) carrageenan gels prepared with various carrageenan concentrations in pure water were completely dried and then swelled in water vapor. Steady state fluorescence measurements were performed using a spectrometer ...
The Effect Of Surfaces On The Orientational Properties and Phase Transitions Peculiarities Of A Nonpolar Smectogen
(World Scientific Publ Co Pte Ltd, 2010)
The effect of thin films on the orientational and optical properties of nonpolar monolayer smectogen 4-butoxyphenyl-4'-decyloxybenzoate ((10) over barO (4) over bar) liquid crystal has been studied by polarizing microscopy ...
Particle Size Effect on the Film-Forming Process of PS/PBA Composite Latexes
(John Wiley & Sons Inc, 2010)
In this work the effect of hard particle size and blend ratio on the film formation behavior of hard polystyrene (PS) and soft poly(n-butyl acrylate) (PBA) latex blends was studied by means of steady-state fluorescence and ...
Comparison of cation effects on phase transitions of kappa and iota carrageenan
(European Polymer Federation, 2010)
Phase transitions of kappa and iota carrageenan in KCl NaCl and CaCl2 solutions were separately studied during heating and cooling processes by using fluorescence technique. Scattered light I-SC and fluorescence intensity ...
Film Formation of Nano-Sized Hard Latex (PS) in Soft Polymer Matrix (PBA): An Excimer Study
(John Wiley & Sons Inc, 2010)
This work reports steady state fluorescence (SSF) technique for studying film formation from pyrene (P)labeled nano-sized polystyrene (PS) and poly(n-butyl acrylate) (PBA) hard/soft latex blends. Blend films were prepared ...
Conductivity percolation of carbon nanotubes (CNT) in polystyrene (PS) latex film
(Canadian Science Publishing Nrc Research Press, 2010)
In this study the effect of multiwalled carbon nanotubes (MWNT) on film formation behaviour and electrical conductivity properties of polystrene (PS) latex film was investigated by using the photon transmission technique ...
Electrical and optical percolations of polystyrene latex-multiwalled carbon nanotube composites
(Academic Press Inc Elsevier Science, 2010)
Electrical conductivity and optical transmittance properties of polystyrene (PS)-multiwalled carbon nanotube (MWCNT) composite films were investigated. Composite films were prepared by mixing of various mass fractions of ...
Drying process in vapor swollen heterogels
(Springer, 2010)
Disk-shaped heterogels were prepared by combining methyl methacrylate (MMA) and styrene (S) with ethylene glycol dimethacrylate (EGDM) as a crosslinker agent in the presence of 22'-azobisisobutyronitrile (AIBN). Swelling ...
Effect of LCST on the swelling of PAAm-NIPA copolymers: a fluorescence study
(Springer, 2012)
Temperature sensitive copolymers were prepared by free radical crosslinking copolymerization in aqueous solution with different molar percentage of N-isopropylacrylamide (NIPA) and acrylamide (AAm) monomers. NN'-methylenebis ...
