In this study we calculate the T-X phase diagram for a mixture of liquid crystals. In this calculation we use a mean field theory We fit our calculated phase line equations to the experimental data from the literature. There is a very good agreement between our calculated and the experimentally observed phase diagram.

Calculation of the T – X phase diagram of tetradecane + hexadecane and tetradecane + pentadecane under high pressure by the landau mean field theory
Tari, O.; Yurtseven, Hasan Hamit (2022-08-01)
© 2022 Elsevier B.V.Landau phenomenological model is applied to two binary mixtures (tetradecane + hexadecane and tetradecane + pentadecane) to calculate T−x (temperature - composition) phase diagram under high pressure for their solid – liquid equilibria. The phase line equation derived from the free energy of the solid phase is fitted to the experimental liquidus curve (T−x) from the literature and the parameters in the Landau expansion are determined. As observed experimentally, variation of the temperat...
Calculation of the Raman frequencies as a function of temperature in phase I of benzene
Tari, O.; Yurtseven, Hasan Hamit (2013-06-01)
This study gives our calculation of the Raman frequencies of the lattice modes A (A(1g)), B (A(g)B(2g)) and C (B1gB3g) as a function of temperature at constant pressures of 0, 1.4 and 3.05 GPa for the solid phase I of benzene. The Raman frequencies of those lattice modes are calculated using the volume data from the literature through the mode Gruneisen parameters for the solid phase I of this molecular crystal. It is shown here that the Raman frequencies of the lattice modes studied decrease with increasin...
Calculation of the Raman frequencies as a function of pressure in the solid phases II and III (III ') of benzene
Yurtseven, Hasan Hamit (Springer Science and Business Media LLC, 2013-06-01)
We calculate here the Raman frequencies of the lattice modes A(A (g) ), B(B (2g) ) and C(B (1g) B (3g) ) as a function of pressure at room temperature for the solid phases (II, III and III') of benzene. This calculation is performed using volume data through the mode Gruneisen parameter. It is found that our calculated frequencies of those lattice modes increase with increasing pressure, as expected. Calculated frequencies are in good agreement with the measurements of the three lattice modes for the solid ...
Calculation of the Raman frequencies of lattice modes in the disordered phase II of NH4Br at high pressures
Yurtseven, Hasan Hamit (Physics Essays Publication, 2010-01-01)
The Raman frequencies are calculated here at various temperatures for the nu(7) (56 cm(-1)) and nu(5) (134 cm(-1)) lattice modes in the disordered phase II of NH4Br. The lattice parameter data obtained at zero pressure are used to calculate the Raman frequencies of those modes studied for constant pressures of 0.1, 108, and 637.5 MPa in phase II of the NH4Br crystal. Through the mode Gruumlneisen parameter which is kept constant in the disordered phase II, the Raman frequencies calculated decrease linearly ...
Calculation of the thermodynamic quantities from the Raman frequency shifts and the Pippard relations for the alpha, -alpha and alpha ' phases of oxygen
Tari, O.; Yurtseven, Hasan Hamit (2018-01-01)
Thermodynamic quantities such as the isothermal compressibility, thermal expansion and the difference in the specific heat are calculated as a function of pressure (T=10 K) for the alpha,-alpha and alpha ' phases of oxygen using the observed Raman frequencies of the two librons and one vibron from the literature through the mode Gruneisen parameter for this molecular solid. Calculated thermodynamic quantities decrease with increasing pressure with some discrepancies due to the different pressure - induced R...
