Linear variations of the thermodynamic quantities in the liquid phase of carbon tetrachloride close to the melting point Yurtseven, Hasan Hamit (Elsevier BV, 2008-03-15) We verify here a linear variation of the specific heat C-p with the thermal expansivity alpha(p) and also a linear variation of alpha(p) with the isothermal compressibility K-T for the liquid phase of carbon tetrachloride close to the melting point.
Temperature dependence of the specific heat of anisaldazine close to phase transitions Kilit, E.; Yurtseven, Hasan Hamit (Elsevier BV, 2008-04-15) The experimental data for the specific heat C-p is analyzed at various temperatures close to the nematic-isotropic liquid (T-NI = 180.5 degrees C) and the solid-nematic (T-SN = 168.9 degrees C) transitions in anisaldazine.
Temperature and pressure dependence of molar volume in solid phases of ammonia near the melting point Yurtseven, Hasan Hamit (Elsevier BV, 2008-08-20) Temperature and pressure dependencies of the molar volume are studied here along the transition curve between solid I and solid II phases near the melting point in ammonia. The molar volumes are calculated in the temperature range of 217 to 224 K and in the pressure range of 3 to 8 kbar with respect to the triple point (T-t=217.34 K. P-t=3.070 kbar) where the melting curves of solid I and solid II coincide with the transition curve in ammonia.
Temperature effect on dark electrical conductivity, Hall coefficient, space charge limited current and photoconductivity of TlGaS2 single crystals Qasrawi, AF; Hasanlı, Nızamı (IOP Publishing, 2005-05-01) The dark electrical conductivity, Hall coefficient, space charge limited current, and illumination and temperature dependences of the photocurrent of TIGaS2 single crystals in the temperature regions of 100-350, 200-350, 200-290 and 100-350 K, respectively, have been measured and analysed. The Hall coefficient measurements revealed the extrinsic type of conduction with conductivity-type conversion from p- to n-type at a critical temperature of 315 K. The temperature dependence of the dark electrical conduct...
Dielectric Properties of HDOBAMBC Close to the Smectic A-Chiral Smectic C (AC*) Transition Yurtseven, Hasan Hamit (Informa UK Limited, 2015-06-01) The temperature dependence of the dielectric susceptibility chi(g) is recalculated by making the elastic modulus K temperature dependent for the chiral smectic C phase in HDOBAMBC. For this calculation, the experimental data for the spontaneous polarization P-S, tilt angle theta and the helical pitch rho are used from literature close to the AC* transition in HDOBAMBC. The temperature dependences of the wave vector of the helical modulation q, the elastic free energy F and the critical electric field E-C ar...
