EHPRG

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.

Harnessing nanofluidic rectification for electrically driven water purification


Nature Materials, Published online: 18 June 2025; doi:10.1038/s41563-025-02271-1

Electro-osmotic flow rectification, a nonlinear nanofluidic effect, has been scaled up to the membrane level. This effect allows for continuous water purification using oscillating electric fields and achieves a performance equivalent of up to 15 bars of pressure per applied volt. This approach offers a scalable, energy-efficient alternative to pressure-driven filtration and electrodialysis.

Neural Canonical Transformations for Quantum Anharmonic Solids of Lithium
by Qi Zhang, Xiaoyang Wang, Rong Shi, Xinguo Ren, Han Wang, and Lei Wang
Author(s): Qi Zhang, Xiaoyang Wang, Rong Shi, Xinguo Ren, Han Wang, and Lei Wang


Lithium is a typical quantum solid, characterized by cubic structures at ambient pressure. As the pressure increases, it forms more complex structures and undergoes a metal-to-semiconductor transformation, complicating theoretical and experimental analyses. We employ the neural canonical transformat…

Neutron diffraction reveals that superconductivity in UTe2 emerges near an incommensurate antiferromagnetic phase under pressure, pointing to antiferromagnetic—rather than ferromagnetic—correlations as a key driving force.

Colloquium: Room temperature superconductivity: The roles of theory and materials design
by Warren E. Pickett
Author(s): Warren E. Pickett


Superconductivity, discovered in 1911 and first theoretically understood in 1957, remains a fascinating phenomenon for reasons both fundamental and applied. Reliably calculating the critical temperature of a given material, and even more so predicting it, turned out to be a considerable challenge. This Colloquium explains how theoretical developments have led to increasingly reliable predictions that have culminated in the discovery of the hydride materials that display superconductivity under high pressure at temperatures just shy of room temperature.

Sodium (Na), silicon (Si), and oxygen (O) are main abundant elements to form the minerals inside the Earth's interior. Here, combining first-principles calculations and crystal structural prediction methods, we propose the formation of a distinct stoichiometry, ${\mathrm{Na}}_{6}{\mathrm{SiO}}_{5}$,…

Fully thermal meta-GGA exchange correlation free-energy density functional
by Katerina P. Hilleke, Valentin V. Karasiev, S. B. Trickey, R. M. N. Goshadze, and S. X. Hu
Author(s): Katerina P. Hilleke, Valentin V. Karasiev, S. B. Trickey, R. M. N. Goshadze, and S. X. Hu


Warm dense matter (WDM) is the materials regime that bridges condensed matter and plasmas that occurs in giant-planet centers and the state trajectory of inertial confinement fusion experiments. Predictive density functional theory simulations of WDM must use an explicitly temperature-dependent free-energy exchange-correlation functional. Incorporating thermal effects at the meta-GGA level of refinement, the newly developed fully thermal fTSCAN functional provides high accuracy across the entire temperature and pressure range from ambient to extreme conditions. Tests on model systems highlight the contributions of thermal and density inhomogeneity effects, while molecular dynamics simulations demonstrate accuracy for materials ranging from water under ambient conditions to dense hydrogen at a wide range of temperatures.

High-pressure floating zone crystal growth of ${\text{Sr}}_{2}{\text{IrO}}_{4}$
by Steven J. Gomez Alvarado, Yiming Pang, Pedro A. Barrera, Dibyata Rout, Claudia Robison, Zach Porter, Hanna Z. Porter, Erick A. Lawrence, Euan N. Bassey, and Stephen D. Wilson
Author(s): Steven J. Gomez Alvarado, Yiming Pang, Pedro A. Barrera, Dibyata Rout, Claudia Robison, Zach Porter, Hanna Z. Porter, Erick A. Lawrence, Euan N. Bassey, and Stephen D. Wilson


Here we demonstrate the floating zone crystal growth of the ${J}_{\mathrm{eff}}=1/2$ Mott insulator ${\mathrm{Sr}}_{2}{\mathrm{IrO}}_{4}$. Historically, the growth of iridates from a ternary melt has been precluded by the extreme vapor pressure of the metal oxide species and the difficulty of mainta…

Author(s): G. Lamura, H. Ninomiya, R. Khasanov, K. Kawashima, N. Takeshita, H. Ogino, and T. Shiroka


In the search for superconductivity with a high critical temperature ${T}_{c}$, new materials with light elements are expected to favor electron-phonon coupling at higher frequencies, thus achieving a higher ${T}_{c}$. Due to their typically stiff bonds and the small atomic masses, carbon intercalat…
