The unions listed below were created to promote high-pressure science and technology. They join a number of research groups from different countries.
AIRAPT grew from the Gordon Research Conference on Research at High Pressures (GRCHP), the first one of which was held in 1955
COMPRES, the Consortium for Materials Properties Research in Earth Sciences is a community-based consortium whose goal is to enable Earth Science researchers to conduct the next generation of high-pressure science on world-class equipment and facilities. It facilitates the operation of beam lines, the development of new technologies for high pressure research, and advocates for science and educational programs to the various funding agencies.
At the 14th Congress of International Union of Crystallography in Perth (1987) a High-Pressure Group was established to represent and support high-pressure crystallography
The Deep Carbon Observatory is a global community of multi-disciplinary scientists unlocking the inner secrets of Earth through investigations into life, energy, and the fundamentally unique chemistry of carbon
The European High Pressure Research Group originated in the initiative taken by the High Pressure Section of Standard Telecommunications Laboratories (now Bell Northern Research Laboratories), Harlow (UK), in 1963, to bring together scientists active in field of high pressure research for informal discussion of common problems
The Japan Society of High Pressure Science and Technology established in October 1989 by organizing group of the annual meeting (the High Pressure Conference of Japan) and its participants unites physicists, chemists, biologists, Earth and space scientists under a common subject of "high pressure". The primary mission of JSHPST is to promote exchange and collaborative activities in the researchers and engineers.
The MALTA project gathers more than seventy scientists of eleven Spanish research groups dedicated to the study of diverse high pressure phenomena under a variety of different perspectives. It is the synergy from the cooperation among the participant groups that provides a real added-value to this ambitious project and confers worth to this initiative.
