Synthesis and liquid crystalline behavior of random copolymer of poly(ethylene oxide) macromonomer and liquid crystalline monomer by the photon transmission technique
(Taylor & Francis Inc, 2005-12)
Random copolymers of poly(ethylene oxide) macromonomer with p-vinylbenzyl end-functional group (PEOVB) and liquid crystalline monomer, namely 6-(4-cyanobiphenyl-4'-oxy)hexyl acrylate (COA), were prepared by conventional ...
Phase transitions of kappa-carrageenan gels in various types of salts
(John Wiley & Sons Inc, 2006-11-05)
Sol-gel and gel-sol phase transitions of K-carrageenan in various types of salts were studied using photon transmission technique. Here, LiCl, NaCl, KCl, MgCl2, CaCl2, and SrCl2 were chosen as the proper salts for the ...
Electron-phonon mass enhancement parameter of the (Gamma) over-bar surface state on Au(111) measured by photoemission spectroscopy
(American Physical Society, 2006-07)
We report the measurement of lambda, the electron-phonon mass enhancement parameter, for the spin-orbit-split Gamma surface state on Au(111). lambda is determined from the change of the photoemission linewidth as a function ...
Bifurcation of drift shells near the dayside magnetopause
(Amer Geophysical Union, 2007-07-10)
Close to the dayside magnetopause, there is a region of space where each field line has two magnetic field minima, one near each cusp. That region is located around local noon, and extends about 1-2 R-e from the magnetopause. ...
Universality of sol-gel phase transition of kappa-carrageenan in various salts: a steady state fluorescence study
(Taylor & Francis Ltd, 2007-08)
Thermal phase transitions of kappa-carrageenan in NaCl, KCl and CaCl2 solutions were studied using steady state fluorescence (SSF) technique. Pyranine was introduced as a fluorescence probe for studying sol-gel phase ...
Study of drying of kappa-carrageenan gel at various temperatures using a fluorescence technique
(Taylor & Francis Inc, 2008-01)
The steady-state fluorescence technique was used to study drying of kappa-carrageenan gel at various temperatures. Pyranine was doped as a fluorescence probe, and scattered light, I-sc, and fluorescence intensities, I, ...
Numerical calculations of relativistic electron drift loss effect
(Amer Geophysical Union, 2008-09-09)
It has been suggested that drift loss to the magnetopause can be one of the major loss mechanisms contributing to relativistic electron flux dropouts. In this study, we examine details of relativistic electrons' drift ...
Measurement and assessment of fatigue life of spot-weld joints
(Asme-Amer Soc Mechanical Eng, 2009-01)
Spot-weld joints are commonly used to fasten together metal sheets. Because fatigue fracture is the most critical failure mode for these joints under fluctuating loads, understanding their fatigue failure behavior and ...
Synergistic effect of the locust bean gum on the thermal phase transitions of kappa-carrageenan gels
(Elsevier Sci Ltd, 2009-03)
Synergism between K-carrageenan and locust bean gum (LBG) was studied using the photon transmission technique. Synergistic effects in these polymeric mixtures strongly affected the physical properties of the gel structure. ...
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. ...
