High-pressure chemistry

High-pressure chemistry is an interdisciplinary science exploring reactions and phenomena occurring at pressures above 100 kPa. Under these extreme conditions, substances undergo remarkable transformations, from quantum state alterations to the emergence of exotic stoichiometries. Beyond its role as a boundless source of scientific fascination, high-pressure chemistry unlocks high-yield processes that can save time and eliminate the need for catalysts, all while working with minuscule quantities of materials. Since the pioneering laboratory syntheses of diamond and cubic boron nitride in the late 20th century, high-pressure chemistry has evolved into an indispensable tool for both fundamental and applied materials chemistry. Recognizing the immense potential of this interdisciplinary field for structural exploration and sustainable material synthesis, this Communications Chemistry Collection seeks to encourage further advancements in this exhilarating realm of research.

We aim to cover a comprehensive range of topics related to chemical research at high-pressure. We welcome submissions exploring:

  • Design and high-pressure synthesis of new inorganic and organic materials and new material phases, including but not limited to materials that can be recovered at room pressure, finding applications as ultrahard, luminescent, or high-energy-density materials, high-transition-temperature superconductors, etc.
  • High-pressure phenomena and reaction pathways, structure transformations and transitions between solids, liquids, gases, or supercritical phases.
  • Theoretical and computational high-pressure chemistry, aiming at synthesis planning as well as at structure exploration or mechanistic elucidation.
  • Applications of high-pressure chemistry in environmental remediation, sustainable synthesis, and green chemistry.
  • Advanced monitoring techniques for high-pressure chemical reactions, shedding light on the dynamic evolution of chemical transformations at extreme pressures.
  • Method development for generating high static and dynamic pressures and for quenching high-pressure phases.

The Collection primarily welcomes original research papers, in the form of both full articles and communications. All submissions will be subject to the same review process and editorial standards as regular Communications Chemistry articles.
