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 ...
Component resolved OSL dose response and sensitization of various sedimentary quartz samples
(Elsevier Ltd, 2007-02)
The structure of the linearly modulated optically stimulated luminescence (LM-OSL) signal was studied for four sedimentary quartz samples, collected from different sites around Istanbul, Turkey. Applying a computerized ...
Ceramic encapsulated latex composites
(Elsevier Inc, 2006-04-15)
This work reports the encapsulation of latex particles in Al(2)O(3)-polystyrene (PS) composite films. These films were prepared from PS particles in Al(2)O(3) dispersion at room temperature in various latex contents. ...
A photon transmission study for film formation from poly(vinyl acetate) latex particles with different molecular weights
(John Wiley & Sons Inc, 2007-10-15)
The photon transmission technique was used to monitor the temperature evolution of film formation from poly(vinyl acetate) (PVAc) latex particles with two different molecular weights. Two sets of latex films were prepared ...
The correlation of fast OSL component with the TL peak at 325 degrees C in quartz of various origins
(Elsevier Science BV, 2010-02)
The fast component of the optically stimulated luminescence (OSL) signal in quartz is the basic tool for the optical dating. Its relation with the thermoluminescence (TL) glow-peak at about 325 degrees C is well established ...
Thermally assisted OSL from deep traps in Al2O3:C
(Pergamon-Elsevier Science Ltd, 2010-03)
The present work suggests an alternative experimental method in order to not only measure the signal of the deep traps in Al2O3:C without heating the sample to temperatures greater than 500 degrees C, but also use this ...
Investigation of beachrock using microanalyses and OSL dating: a case study from Bozcaada island, Turkey
(Coastal Education & Research Foundation, 2010-03)
We investigated the origin and absolute age of beachrock samples on Bozcaada Island, located on the northern Aegean Sea coast of Turkey, using energy dispersive X-ray spectroscopy (EDX) and scanning electron microscopy ...
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, ...
Investigation of OSL signals from very deep traps in unfired and fired quartz samples
(Elsevier Science BV, 2010-03-15)
This paper presents an attempt to isolate experimentally optically stimulated luminescence (OSL) signals which may originate from very deep traps (VDT) in quartz samples. As VDT we consider those traps which are responsible ...
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 ...
