Pressure is one of the fundamental thermodynamic variables. It affects intermolecular interactions and interatomic properties. Under extreme conditions such as high pressure, materials exhibit properties which can be remarkably different from those observed at ambient conditions. Advances in high pressure research have shown that it can be used to produce exotic materials with a range of different characteristics such as superhardness, superconductivity, and novel mechanical properties.
This Collection is open to research investigating high pressure techniques, applications, and products, including methods of retaining properties gained under high pressure once the sample is returned to ambient conditions.
Pressure, as one of the fundamental thermodynamic parameters, can profoundly change the interatomic distances, electronic interactions, chemical bonding and crystal structures, leading to exotic structures and properties of materials. High-pressure techniques have significantly impacted disciplines like physics, chemistry, geology, and life science, creating new materials, advancing knowledge of Earth's interior, and influencing pharmaceutical development. This editorial reviews the latest research published in this Collection, highlighting the potential of high-pressure studies to further our understanding of materials’ behavior under extreme conditions.
