THEORETICAL STUDY OF NANOMATERIALS AT HIGH PRESSURE FROM EOSs

In present the work, we have theoretically calculated some important thermoelastic properties of nanomaterials under high compression, such as pressure, isothermal bulk modulus and percentage deviation of pressure of nanomaterials by using four different Equation of States (EOSs): viz. (I) Birch-Murnaghan EOS, (II) Bardeen EOS (III) Poirier- Tarantola and (IV) Suzuki EOS for 37nm Al2O3, 67nm Al2O3, 3C-SiC, nano-Ni and nano-ε-Fe nanomaterials. The result shows that the pressures increase as compression increases, which is in good agreement with experimental value. The bulk modulus also increases as compression increases, and computed value of percentage deviation in pressure at high compression this is demonstrates satisfying result across the entire compression range but the nano-ε-Fe nanomaterial percentage deviation shows excellent result with Poirier -Tarantola EOS.
