Summary: In this study, the pressure, bulk modulus, and first order pressure derivative of bulk modulus at different compression ratios (V/V0) were theoretically calculated to investigate the Gruneisen parameter in nanomaterials. The variation of Gruneisen parameter with respect to compression ratio (V/V0) for gamma-Fe2O3 nanomaterial was also predicted using the Borton and Stacey model at compressions up to V/V0 = 0.64. Three different equations of state were used: Birch-Murnaghan EOS, Brennan-Stacey EOS, and Vinet-Rydberg.

Summary: In this study, three equations of state (EOSs) including modified Lenard Jones EOS, Birch-Murnaghan (3rd) EOS, and Vinet-Rydburg EOS, were used to investigate the thermoelastic properties of carbon nanotubes under high pressure. The calculated pressures at various V/V-0 values matched well with experimental data, indicating the applicability of these EOSs for nanomaterial calculations. The findings of this study were consistent with the work of Stacey, demonstrating that pressure increases with a decrease in volume, while bulk modulus increases with an increase in pressure. Moreover, the Gruneisen parameter calculated from different EOSs followed the relationship that the ratio of Gruneisen parameter to V/V-0 remains approximately constant.

Summary: In this theoretical analysis, we examined the binding energy of metal and halogen atom pairs by using different mathematical models. The comparison between theoretical predictions and experimental measurements showed that the difference between them becomes more noticeable as the force constant increases. These findings are related to the rotation and vibration of atoms, which are key areas of study in molecular spectroscopy.

Summary: In this theoretical investigation, the limitations of EOSs at high pressures have been examined by analyzing the relationship between pressure and bulk modulus. A new relationship has been established for the infinite pressure range, and the applicability of different EOSs has been analyzed. The findings shed light on the constraints and potential improvements of EOSs for accurately predicting material behavior at infinite pressures.

Summary: The present study conducts a theoretical calculation to analyze the effects of high pressure on the thermodynamic properties of GaN. The results show that the bulk modulus of GaN increases with pressure, while the volume change is relatively small. Additionally, the theoretical calculations are in good agreement with experimental data, indicating the validity of the equations of state used in this study.
