Optical data carriers such as DVDs, Blu-rays and CD-RWs store data in layers of so-called "phase change materials". In the future, these materials will enable the development of fast, non-volatile and energy-saving main memories. ...

(PhysOrg.com) -- A well-insulated mug may keep your coffee somewhat warm, but now scientists have designed a high-tech mug that can keep drinks hot or cold at the perfect temperature for up to half an hour.
When temperature or pressure is applied to a material, its state changes from liquid to solid or remains solid but exhibits structural changes. This change is called a phase transition or change.
