New Technique ‘Defies’ Laws of Physics

Pressure-induced transitions are associated with near two-fold volume expansions. While an increase in volume with pressure is counterintuitive, the resulting new phases contain large fluid-filled pores, such that the combined solid-fluid volume is reduced and the inefficiencies in space filling by the interpenetrated parent phase are eliminated (Argonne National Laboratory)

Researchers at Argonne National Laboratory, Illinois, have found a way to apply pressure to make a material expand instead of compress. Pressure-induced transitions are associated with near two-fold volume expansions. While an increase in volume with pressure is counterintuitive, the resulting new phases contain large fluid-filled pores, such that the combined solid-fluid volume is reduced and the inefficiencies in space filling by the interpenetrated...
