Effect of the Interface on the Compressibility of Substances with Spherical Nano-Inhomogeneities on the Example of Al/C.

The paper examines the compressibility of media with nano-inhomogeneities using the example of an aluminum melt and C fullerenes immersed in it. The results of molecular dynamics simulations indicate a significant effect of the interface on the effective compressibility of a heterogeneous medium. It is found that the application of the rule of mixture for the Al/C system results in an incorrect qualitative picture of the dependence of compressibility on the concentration of fullerenes.
