EHPRG: The European High Pressure Research Group

Welcome

Welcome to the official website of the European High Pressure Research Group (EHPRG).

EHPRG is non-profitable academic association established in 1963 which is devoted to science and technology of matter under high pressure. It organizes an annual meeting which brings together hundreds of scientists of various fields, mainly physics, chemistry, Earth and planetary sciences, bio- and food science and technology.

The reasonable size of the group, low conference fees, and a friendly relationship between the attendants have made EHPRG meetings a major event in the European high-pressure community for more than half a century.

Upcoming EHPRG Meeting

The 63rd EHPRG Meeting will take place in Montpellier, France, in the period August 23-28, 2026.
The conference will be chaired by Julien Haines and Jérôme Rouquette, ICGM, Université de Montpellier, France.
Registration in now open. The deadline for the reduced registration fee is April 30th, 2026.
EHRPG 2026 will deal with a wide range of high-pressure studies from Bio/Life Sciences, Food Science and Technology, Physics, Chemistry, Geo- and Planetary Sciences, High-Pressure Crystallography, Instrumentation, Theory...
Further information is available on the conference website: https://ehprg2026.org/

Immediate past EHPRG Meetings

The 62nd EHPRG Meeting took place in Manchester, UK, at the Lowry, in the period August 31-September 5, 2025.
The conference was chaired by John Proctor, Salford University, UK.

For more information, please visit the official webpage of EHPRG-61.

The Joint 28th AIRAPT and 60th EHPRG International Conference on High Pressure Science and Technology (AIRAPT-2023) took place in Edinburgh, UK, at the Edinburgh International Conference Centre (EICC), from July 23-28, 2023.
Immediately prior to AIRAPT/EHPRG, from the 19th to 23rd of July 2023, a Summer School had taken place, also based in Edinburgh, with accommodation provided in University Halls of Residence. The School was aimed at young researchers, and experimentalists wanting a grounding in theory and vice versa.
A photo album is available on the AIRAPT website.

Midair Single-Sided Acoustic Levitation in High-Pressure Regions of Zero-Order Bessel Beams

by Yusuke Koroyasu, Christopher Stone, Yoichi Ochiai, Takayuki Hoshi, Bruce W. Drinkwater, and Tatsuki Fushimi

Acoustic levitation enables noncontact manipulation using sound waves. While conventional methods entrap particles at pressure nodes (zero-pressure region surrounded by high pressure), we demonstrate stable acoustic levitation and translation in midair within a high-pressure axial core of a zero-ord…

Pressure effects on metals, alloys, and compounds of transplutonium elements

by Tyler W. Hines, Nicholas B. Beck, Kacy N. Mendoza, Joseph M. Sperling, and Thomas E. Albrecht

Materials containing transplutonium elements (the actinides Am–Cm that come after Pu in the periodic table) are important for nuclear power, nuclear waste management, and long-term storage. They also have fascinating properties, with 5f electrons that lie at the boundary of being localized and itinerant. This paper reviews the physics and chemistry of transplutonium compounds under high pressure, covering both traditional metals, alloys, and compounds, as well as recent work on coordination complexes. Both the theory and experiments are challenging due to the high radioactivity and the complexity of studying heavy elements with both itinerant and localized electrons. The reviewed work represents a tour-de-force expansion of our understanding of the unique behavior of these materials.
