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 ... -
Effect of annealing rate on film formation from poly(vinyl acetate) latex particles
(Taylor & Francis Ltd, 2008)The photon transmission technique was used to monitor the time and temperature evolution of film formation from poly(vinyl acetate) (PVAc) latex particles. The latex films were prepared below the glass transition temperature ... -
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 ... -
Film formation from nano-sized polystrene latex covered with various TiO2 layers
(Wiley, 2006-12)Steady-state fluorescence technique was used for studying film formation from TiO2 covered nano-sized polystyrene latex particles. The composite films were prepared from pyrene (P)-labeled PS particles by covering them ... -
Film formation stages for poly(vinyl acetate) latex particles: a photon transmission study
(Springer-Verlag, 2006-07)Photon transmission technique was used to monitor the evolution of transparency during film formation from poly(vinyl acetate) (PVAc) latex particles. The latex films were prepared below the glass transition temperature ... -
Fluctuation theory of the liquid-glass transition
(Trans Tech Publications Ltd, 2004)The glassy state and the character of the liquid-glass transition from undercooled liquid to amorphous solid is one of the biggest challenges of our time. In spite of significant progress we still cannot explain accurately ... -
Future global meteorological drought hot spots: A study based on CORDEX data
(American Meteorological Society, 2020-05-01)Two questions motivated this study: 1) Will meteorological droughts become more frequent and severe during the twenty-first century? 2) Given the projected global temperature rise, to what extent does the inclusion of ... -
Impacts of climate change on precipitation climatology and variability in Turkey
(Springer International Publishing Ag, 2020)In this chapter, changes in seasonal precipitation climatology, extreme weather conditions, and aridity conditions of Turkey are evaluated for the period of 2021-2050 with respect to the reference period of 1971-2000 by ... -
In situ fluorescence study of swelling, sorption and desorption processes in and out of PAAm gels
(Wiley-V C H Verlag GMBH, 2008-05)Small molecule sorption and desorption in and out of polyacrylamide (PAAm) gels were studied at various temperatures. Pyranine (P(y)) dissolved in water used as a probe. Fluorescence emission intensity, I(p) from P(y) was ... -
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 ... -
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 ... -
