Abstract:
To predict the most suitable EOS for analysis of real compression behavior
of nanomaterials such as C60 solid, CdSe (5.4 nm), Ni-filled MWCNT, Fe-filled MWCNT, CNT, and ∝-Fe nanotubes under isothermal compression.
we have used Murnaghan, Tait EOS, based on thermodynamical
approximation and the results of the experiment have been compared. The
analysis of computed results suggests that Tait and Murnaghan’s EOS is in
good agreement with the experimental data that is already known, proving
the correctness of the formulation used in this study in the entire range of
pressure. Surprisingly it is also observed that the Murnaghan formulation
gives a better agreement with the experimental result for carbon nanotubes
than the Tait formulation.Thus, it is concluded that thewell-known and
widely used Murnaghan EOS is still most suitable and valid for bulk as well
as nanomaterials.The present study also reveals the fact that the carbon
Nanotubes are less compressible than Ni-filled MWCNT, and Fe-filled
MWCNT.
