The symposium will be an interdisciplinary meeting for discussing recent trends and developments in the science of materials submitted to extreme conditions of pressure. The development and dissemination of new experimental, computational and theoretical tools have enormously increased the possibility to exploit how this fundamental thermodynamic parameter affects the physics and chemistry of different materials. The proposal is bring together basic and applied researchers working in this field, using high-pressure in a broad spectrum of approaches, including: study of basic materials properties, induction of electronic, magnetic and structural changes, production of novel materials, development of materials processing and analytical techniques, theoretical modeling and use of the state of the art computational tools.
