Illustration of the mechanical equations of state for a variety of materials. Upper row: free energy profile; middle row: mechanical equations of state; bottom row: volume versus external trigger. a Free energies, mechanical equations of state PNT(V) and V(P) profiles for Al-Fumarate, MIL-53(Ga), MIL-53(Al)-F, MIL-53 and DUT-49(Cu) (DUT-49(Cu) axis are shown in olive green). b Free energies, mechanical equations of state PN(V;T) and V(T) profiles for MIL-53(Al)-F. c,d Free energies, mechanical equations of state PT(V;N) and V(N) profiles for methane@Co(bdp) and benzene@DMOF-1(Zn)
