Study Explores Remarkable Negative Thermal Expansion Seen in Layered Ruthenates

A formerly unnoticed monoclinic distortion in Ca2RuO4 explains its enormous negative thermal expansion (NTE) over a wide range of temperatures, discover researchers from Tokyo Tech. The work promises a different route for the design of unconventional NTE materials, with applications in engines, thermal barrier ceramics, and precision instruments, among other things.
