A hybrid material that switches reversibly between two stable solid states
(PHYSorg.com Chemistry)

Solid matter typically contains a single, stable solid state for a specific set of conditions. Materials scientists envision that new materials with interchangeable solid states will be advantageous for diverse technical applications. In a new report now published on Nature Materials, Fut (Kuo) Yang and colleagues in the interdisciplinary departments of Chemical Engineering, Bioengineering and Biotechnology in Canada and China described the development of a two-in-one hybrid material.
