Cation effect on gel-sol transition of kappa carrageenan
(Springer, 2008-04)
The steady state fluorescence (SSF) technique was employed to study gel - sol transitions of kappa carrageenan in NaCl, KCl and CaCl2 solutions. Pyranine was used as a fluorescence probe for monitoring these transitions. ...
Tunneling rates of single electrons on liquid helium in an extracting field
(Springer/Plenum Publishers, 2009-02)
We calculated the tunneling rates of single electrons from the quasi-stationary states on both liquid He-4 and He-3 in an extracting electric field. The rates were obtained from the widths of the resonance lineshapes of ...
Sorption and slow release kinetics of PAAM gels at various temperatures
(Freund Publishing House Ltd, 2007-11)
Small molecule sorption and slow release in and out of polyacrylamide (PAAm) gels were studied by using steady state fluorescence (SSF) technique. Pyranine (P-y) dissolved in water used as a probe. Fluorescence emission ...
Thermoluminescence and optically stimulated luminescence properties of natural barytes
(Elsevier Ltd, 2010-12)
Heavy, baryte-loaded, concrete is commonly used as radiation shielding material around high energy particle accelerators. Concrete samples received from a shielding block located at CERN cite contain many crystalline ...
Age, composition and paleoenvironmental significance of a Late Pleistocene eolianite from the western Black Sea coast of Turkey
(Pergamon-Elsevier Science Ltd, 2013-05-16)
On the basis of field observations, thin section interpretations, microanalytical data, electrical resistivity survey and luminescence dating, the age, composition and internal structure of coastal eolianite on the west ...
A realistic quantum capacitance model for quantum Hall edge state based Fabry-Pérot interferometers
(Institute of Physics Publishing, 2017-01-25)
In this work, the classical and the quantum capacitances are calculated for a Fabry-Pérot interferometer operating in the integer quantized Hall regime. We first consider a rotationally symmetric electrostatic confinement ...
Strategies for the evolution of sex
(American Institute of Physics Inc., 2001-12)
The maintenance of a macroscopic sexual population is addressed. As a scenario, the mechanism of random conversion to sex, in the presence of a constant rate of mutation is examined. This scenario is very closely related ...
Determination of pre-gelation and post-gelation activation energies during free radical crosslinking copolymerization
(Taylor & Francis Ltd, 2005)
Steady-state fluorescence (SSF) and dilatoraetric techniques were used to study the free-radical crosslinking copolymerization (FCC) of styrene (S) and divinylbenzene (DVB) in bulk. The gel points (t g) were recorded by ...
Dissolution of Al2O3-polystyrene latex composites: A fluorescence study
(Taylor & Francis Ltd, 2005)
This work reports the use of the steady state fluorescence (SSF) technique to study dissolution of a composite film formed from a mixture of Al 2O3 and polystyrene (PS) latex particles. The composite films were cast from ...
Reversible film formation from PS doped PNIPAM particles in various compositions
(John Wiley & Sons Inc, 2008-02)
Film formation from polystyrene (PS) doped poly(N-isopropylacrylamide) (PNIPAM) particles was studied using photon transmission technique. The transmitted light intensity, Itr, was monitored during film formation process. ...
