Recently, a number of novel compounds have been synthesized at high pressures which hold a promise to become prototypes of new classes of materials with greatly improved for the practical application properties. These include superhard and high energy-density materials, high-temperature superconductors, etc. Other findings include synthesis of materials with chemical compositions, which may be relevant for the planetary interiors. Many of these discoveries have been guided by novel structure search algorithms but the importance of the experimental verification remains decisive. Of particular interest are unusual bonding schemes and modified stoichiometry of these novel materials. In this session we invite theoretical and experimental contributions that enhance newly emerging physics and chemistry at extreme conditions.
