Percolation approach to film formation from surfactant-free polystyrene particles
(Taylor & Francis, 2005-09)
In this study, a film formation process from surfactant-free polystyrene (PS) latex particles is reported. Steady state fluorescence (SSF) and photon transmission (UVV) techniques were used to study the evolution of film ...
Effects of annealing on morphology of polymer/polymer (PS/PMMA) blend; a fluorescence study
(John Wiley& Sons Inc, 2006-05-05)
Steady state fluorescence (SSF) technique conjunction with optical microscopy were used to study the morphology of polystyrene (PS)/poly(methyl methacrylate) (PMMA) blend upon annealing above glass transition in elevated ...
Swelling activation energy of kappa-carrageenan in its gel state: A fluorescence study
(John Wiley & Sons Inc, 2007-12-15)
A steady-state fluorescence technique was employed to study the swelling Of K-carrageenan gels at various temperatures. Pyranine was used as a fluorescence probe. The fluorescence intensity of pyranine was measured during ...
Electrochromic switching of WO3 nanostructures and thin films
(Springer-Verlag, 2006-04)
We present transmission measurements through tungsten tri-oxide nanostructures and thin films prepared by sol-gel process on micro-contact printed substrates. Identical electrochromic switching times are found for both the ...
Strategies for the evolution of sex
(American Physical Soc, One Physics Ellipse, 2001-12)
We find that the hypothesis made by Jan, Stauffer, and Moseley [Theory Biosci. 119, 166 (2000)] for the evolution of sex, namely, a strategy devised to escape extinction due to too many deleterious mutations, is sufficient ...
Calculation of the T-X phase diagram for a mixture of liquid crystals
(Pergamon-Elsevier Science, 2000-12)
In this study we calculate the T-X phase diagram for a mixture of liquid crystals. In this calculation we use a mean field theory We fit our calculated phase line equations to the experimental data from the literature. ...
Component-resolved thermal stability and recuperation study of the LM-OSL curves of four sedimentary quartz samples
(Elsevier Ltd, 2007-09)
Thermal stability as well as recuperation stands among the crucial general characteristics of different OSL components in quartz. Through a series of thermal stability and recuperation experiments, in conjunction with curve ...
Photon transmission study on conformational ordering of iota-carrageenan in CaCl2 solution
(Taylor & Francis Inc, 2005-06)
Coil-to-double helix (c-h) and double helix-to-dimer (h-d) phase transitions of iota-carrageenan in CaCl2 solution upon cooling were studied using photon transmission technique. Photon transmission intensity, I-iota r was ...
Size-dependent self-organization of colloidal particles on chemically patterned surfaces
(SP Zhejiang University Press, 2006-04-14)
A study of the self-organization of colloidal particles during the evaporation of particle solutions on chemically patterned surfaces is presented. On a surface with hydrophilic and hydrophobic regions, colloidal particles ...
Dissipative dynamics and the statistics of energy states of a Hookean model for protein folding
(Kluwer Academic Publishers-Plenum Publishers, 2000-07)
A generic model of a random polypeptide chain, with discrete torsional degrees of freedom and Hookean spring connecting pails or hydrophobic residues, reproduces the energy probability distribution of real proteins over a ...
