Raman frequencies calculated at various pressures in phase I of benzene
Tarı, Özlem; Yurtseven, Hamit (KCS Publications, 2013)We calculate in this study the pressure dependence of the frequencies for the Raman modes of A (Ag), B (Ag, B2g) and C (B1g, B3g) at constant temperatures of 274 and 294K (room temperature) for the solid phase I of benzene. ... -
Surrogate Based Design Optimization of Multi-Band Antenna
Tarı, Özlem; Aysu, Belen; Mahouti, Peyman; Belen, Mehmet Ali (Institute of Electrical and Electronics Engineers Inc., 2021)In this work, design optimization process of a multiband antenna via the use of Artificial Neural Network (ANN) based surrogate model and meta-heuristic optimizers is studied. For this mean firstly, by using Latin-Hyper ... -
Temperature dependence of magnetic and thermal properties of chiral HyFe and HyMn close to phase transitions by using the Landau mean field model
Tarı, Özlem; Yurtseven, Hamit (Elsevier Science, 2019)Magnetic and thermal properties of chiral metal formate frameworks (MOFs) of NH2NH3M(HCOO)(3), M = Fe, Mn, namely, HyFe and HyMn are investigated close to phase transitions by using Landau phenomenological model. By expanding ... -
Temperature effect on the structural ferroelectric – paraelectric transition in Li2Ge7O15
Yurtseven, Hamit; Tarı, Özlem (Taylor & Francis, 2016)Li2Ge7O15 (LGO) undergoes the ferroelectric – paraelectric transition at Tc D283.5K. The crystal structure of LGO is orthorhombic with the four formula units in the unit cell in the paraelectric phase (T < TC) . The ... -

Variation of the molar volume with the temperature and the Pippard relations near the melting point in benzene
Tarı, Özlem; Yurtseven, Hamit (Elsevier, 2016)In this study, we calculate variation of the molar volume with the temperature at constant pressures (70.5, 85.2, 128 and 175.2 MPa) using the experimental data from the literature for the solid and liquid phases of benzene ... -
Variation of the raman frequency of a soft mode with the pressure (20 oc) for the phase transitions in NH4F
The Raman frequency of a soft mode (238 cm-1) is analyzed as a function of pressure at 20 oC for NH4F using the experimental data from the literature. This analysis is performed for the pressure dependence of the Raman ...
