Abstract

NPs under acoustic shocked conditions are explained by their lattice thermal conductivity values based on a superheating approach. From the observed results, it is confirmed that acoustic shock waves create a new stage, which requires a collective approach for reinvestigating/rewriting the classical P-T phase diagrams, conventional phase transition paths and compression behaviour of materials/minerals because of their unique structural results.
