The liquid–glass transition – is it a fourth order phase transition?
(Elsevier Science, 2005-09-01)The liquid-glass transition is analyzed using a theory of Brownian motion in liquids recently developed by the author. It is shown that if a liquid could be cooled in quasi-static process and still avoids crystallization ... -
LM-OSL thermal activation curves of quartz: Relevance to the thermal activation of the 110 degrees C TL glow-peak
(Pergamon-Elsevier Science Ltd, 2008-01)The thermally activated characteristics (TAC) of the linearly modulated optically stimulated luminescence (LM-OSL) signals of seven quartz samples from different origin were studied relative to the TAC of their respective ... -
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 ... -
Luminescence dating of prehistoric site of smintheion (Gulpinar) in NW Turkey
(Univ Agean, Dept Mediterranean Stud, 2010)This study aims to place the prehistoric settlement of Smintheion in northwestern Turkey in its temporal setting on the basis of the dating of the quartz from pottery and sediments collected from the site employing Optically ... -
Magnetoresistivity of a weakly-screened, low-density, two-dimensional electron liquid
(Physical Soc Japan, 2013-07)We probe the strength of electron-electron interactions at intermediate magnetic fields in the classical regime using magnetoconductivity measurements of two-dimensional, non-degenerate electrons on liquid helium. We span ... -
A mean field model near the NAC point in liquid crystals
(Physical Soc Republic China, 2002-10)In this study we obtain the phase line equations for the nematic-smectic A (NA), smectic A-smectic C (AC) and nematic-smectic C (NC) transitions using a mean field model. We fit these phase line equations to the experimental ... -
A model of AlN layer formation during ion nitriding of Al
(Springer-Verlag, 2004-11)A diffusion model of AlN layer formation by ion nitriding of Al is proposed based on the analysis of atomic transport during the process. This model is reduced to the following. Implantation of N ions to the surface of the ... -
Molecular alignment during gel formation from methyl methacrylate: An excimer fluorescence study
(Taylor & Francis Ltd, 2005-05)Glass transition during bulk polymerization was studied in free-radical cross-linking copolymerization (FCC) of methyl methacrylate (MMA) using the steady-state fluorescence (SSF) technique. Naphthalene (N) was used as a ... -
