||By achieving extreme conditions such as static high pressure, shocking wave, high/low temperature, high magnetic field, irradiations, as well as large strains and quantum confined systems, we are now facing a new era with orders of magnitude more materials to be discovered than all that have been explored at ambient condition. Under extremes, materials will exhibit emergent and/or enhanced properties and functionalities which cannot be obtained using traditional methods. Challenges exist, however, in realizing these extreme systems and the characterization methodology under extremes. In-situ and operando techniques based on accelerator-based large-scale facilities (synchrotron, neutron and free-electron-laser sources) are highly essential to investigate the structure and property changes of the materials under extremes, as well as to develop decisive understanding of the structure-property relationship and the underlying mechanisms for the emergent properties. With the development of the advanced characterizations, together with novel extreme technologies, numerous exciting opportunities are emerging for materials research at extremes. To address the pressing challenges and difficulties, we envision this symposium to highlight most recent findings, trends, and forefront challenges in exploring new materials and novel phenomena related to extreme environments and the cutting-edge characterization technologies.
Topics will include:
• Materials design and exploration under high-pressure and/or high-temperature environments;
• Epitaxial thin films with large strains;
• Quantum confined systems such as low dimensional electron systems (2D electrons and 2D holes);
• Evolution of properties under extremes - mechanical, thermal, electrical, optical, magnetic, etc.;
• Emergent properties and functionalities induced by extreme conditions, the underlying mechanisms, and structure-property relationships;
• In-situ and operando characterizations of functional materials under extreme conditions such as static high pressure, high/low temperature, supercritical environments, high magnetic field, various irradiations (e.g. ions, electrons, photons) and shocking waves etc.;
• Advanced characterization techniques based on synchrotron, neutron, and free-electron-laser facilities -diffraction, scattering, spectroscopy and dynamics/transient techniques.
