Poly (styrene) latex/modified na-activated bentonite nanocomposite films: a fluorescence study
(Elsevier Science BV, 2008-12)
We studied film formation of composites of surfactant-free polystyrene (PS) nanoparticles and modified Na-activated bentonite (MLB), by steady state fluorescence (SSF) technique. The films were prepared from a mixture of ...
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, ...
Luminescence ages of feldspar contaminated quartz from fluvial terrace sediments
(Wind-J Wojewoda Publ Co, 2008-01-01)
This study focuses on obtaining luminescence ages in feldspar contaminated quartz from well-developed fluvial terraces of the Yesilirmak (Iris) river located inside the eastern North Anatolian Fault Shear Zone (NAFZ). We ...
Film formation from PS latex doped PNIPAM hydrogels at various heating and cooling rates
(VSP BV, Brill Academic Publishers, 2008-05-01)
Film formation from polystrene (PS) latex doped poly(N-isopropylacrylamide) (PNIPAM) hydrogels was studied by using photon transmission technique. The transmitted light intensity, It, was monitored during film formation ...
On the Origin and Age of the Ariburnu Beachrock, Gelibolu Peninsula, Turkey
(Scientific Technical Research Council Turkey-TUBITAK, 2008-03-13)
The beachrock formation on the Ariburnu coast situated in the Gelibolu Peninsula has been studied by field observation, thin-section interpretation, physicochemical analyses including ICP-AES and SEM/EDS, and OSL dating. ...
The conformal Penrose limit: back to square one
(IOP Publishing LTD, 2008-08-21)
We show that the conformal Penrose limit is an ordinary plane wave limit in a higher dimensional framework which resolves the spacetime singularity. The higher dimensional framework is provided by Ricci-flat manifolds which ...
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. ...
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. ...
Component resolved IR bleaching study of the blue LM-OSL signal of various quartz samples
(Wind-J Wojewoda Publ Co, 2008-01-01)
The present work provides an initial component resolved analysis concerning the effect of infra-red (IR) exposure at elevated temperatures on the blue LM-OSL signal of quartz (stimulated at 470 nm). The study was performed ...
Swelling of iota-carrageenan gels prepared with various CaCl2 content: A fluorescence study
(European Polymer Federation, 2008-01-05)
Iota carrageenan gels prepared with various CaCl2 content were completely dried and then swelled in water vapor. Steady-state fluorescence ( SSF) technique was used to monitor the swelling process of each iota carrageenan ...
