A simple Theory is proposed to predict the effect of pressure to study the volume expansion of nanomaterials. Different possible forms of equation of state are discussed with their correlations. Only two input parameters, namely, the bulk modulus and its first pressure derivative are required for calculations. We have considered a wide variety of nanomaterials, such as, metals [Ni (20 nm), α-Fe (nanotubes), Cu (80nm) and Ag (55nm)], semiconductors [Ge (49 nm), Si, CdSe (rock-salt phase), MgO (20nm) and ZnO], carbon nanotube (CNT), ZnSe(Zinc Blende 80nm) and Znse(Rocksalt Phase 80nm) to analyze the effects of pressure on them. The results have been compared with the available experimental data as well as with those obtained through other theoretical approaches. A good agreement between theory and experiment demostrates the validity of present approach.
