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 58th European High Pressure Research Group Meeting on High Pressure Science and Technology (EHPRG-2020) will be held in Tenerife, Spain, from 6th to 11th September 2020. The 58th EHPRG Meeting will be chaired by Alfonso Muñoz Gonzalez (Universidad de La Laguna, Tenerife, Spain).

Neutralizing antibodies have become an important tool in treating infectious diseases. Recently, two separate approaches yielded successful antibody treatments for Ebola – one from genetically-humanized mice, and the other from a human survivor. Here, we describe parallel efforts using both humanized mice and convalescent patients to generate antibodies against the SARS-CoV-2 spike protein, yielding a large collection of fully-human antibodies that were characterized for binding, neutralization and three dimensional structure. Based on these criteria, we selected pairs of highly-potent individual antibodies that simultaneously bind the receptor-binding domain of the spike protein, providing ideal partners for a therapeutic antibody cocktail that aims to decrease the potential for virus escape mutants that might arise in response to selective pressure from a single antibody treatment.

High-pressure elastic properties of dolomite melt supporting carbonate-induced melting in deep upper mantle [Earth, Atmospheric, and Planetary Sciences]
by Man Xu, Zhicheng Jing, Suraj K. Bajgain, Mainak Mookherjee, James A. Van Orman, Tony Yu, Yanbin Wang
Deeply subducted carbonates likely cause low-degree melting of the upper mantle and thus play an important role in the deep carbon cycle. However, direct seismic detection of carbonate-induced partial melts in the Earth’s interior is hindered by our poor knowledge on the elastic properties of carbonate melts. Here we report...

Sampling mobility profiles of confined fluids with equilibrium molecular dynamics simulations
by Etienne Mangaud
The Journal of Chemical Physics, Volume 153, Issue 4, July 2020.
We show how to evaluate mobility profiles, characterizing the transport of confined fluids under a perturbation, from equilibrium molecular dynamics simulations. The correlation functions derived with the Green–Kubo formalism are difficult to sample accurately, and we consider two complementary strategies: improving the spatial sampling, thanks to a new estimator of the local fluxes involving the forces acting on the particles in addition to their positions and velocities, and improving the temporal sampling, thanks to the Einstein–Helfand approach instead of the Green–Kubo one. We illustrate this method in the case of a binary mixture confined between parallel walls, under a pressure or chemical potential gradient. All equilibrium methods are compared to standard non-equilibrium molecular dynamics (NEMD) and provide the correct mobility profiles. We recover quantitatively fluid viscosity and diffusio-osmotic mobility in the bulk part of the pore. Interestingly, the matrix of mobility profiles for local fluxes is not symmetric, unlike the Onsager matrix for the total fluxes. Even the most computationally efficient equilibrium method (the Einstein–Helfand approach combined with the force-based estimator) remains less efficient than NEMD to determine a specific mobility profile. However, the equilibrium approach provides all responses to all perturbations simultaneously, whereas NEMD requires the simulation of several types of perturbations to determine the various responses, each with different magnitudes to check the validity of the linear regime. While NEMD seems more competitive for the present example, the balance should be different for more complex systems, in particular for electrolyte solutions for the responses to pressure, salt concentration, and electric potential gradients.

Scalable molecular dynamics on CPU and GPU architectures with NAMD
by James C. Phillips
The Journal of Chemical Physics, Volume 153, Issue 4, July 2020.
NAMDis a molecular dynamics program designed for high-performance simulations of very large biological objects on CPU- and GPU-based architectures. NAMD offers scalable performance on petascale parallel supercomputers consisting of hundreds of thousands of cores, as well as on inexpensive commodity clusters commonly found in academic environments. It is written in C++ and leans on Charm++ parallel objects for optimal performance on low-latency architectures. NAMD is a versatile, multipurpose code that gathers state-of-the-art algorithms to carry out simulations in apt thermodynamic ensembles, using the widely popular CHARMM, AMBER, OPLS, and GROMOS biomolecular force fields. Here, we review the main features of NAMD that allow both equilibrium and enhanced-sampling molecular dynamics simulations with numerical efficiency. We describe the underlying concepts utilized by NAMD and their implementation, most notably for handling long-range electrostatics; controlling the temperature, pressure, and pH; applying external potentials on tailored grids; leveraging massively parallel resources in multiple-copy simulations; and hybrid quantum-mechanical/molecular-mechanical descriptions. We detail the variety of options offered by NAMD for enhanced-sampling simulations aimed at determining free-energy differences of either alchemical or geometrical transformations and outline their applicability to specific problems. Last, we discuss the roadmap for the development of NAMD and our current efforts toward achieving optimal performance on GPU-based architectures, for pushing back the limitations that have prevented biologically realistic billion-atom objects to be fruitfully simulated, and for making large-scale simulations less expensive and easier to set up, run, and analyze. NAMD is distributed free of charge with its source code at www.ks.uiuc.edu.

Molecular dynamics simulations of interfacial properties of the CO2–water and CO2–CH4–water systems
by Parisa Naeiji
The Journal of Chemical Physics, Volume 153, Issue 4, July 2020.
Molecular dynamics simulations were performed to study the interfacial behavior of the pure carbon dioxide–water system and a binary 40:60 mol. % gas mixture of (carbon dioxide + methane)–water at the temperatures of 275.15 K and 298.15 K and pressures near 4 MPa for CO2 and up to 10 MPa for methane. The simulations are used to study the dynamic equilibrium of the gases at the water–gas interface, to determine the z-density profiles for the gases and water, and calculate the interfacial tension γ under the different temperature/pressure conditions close to those of the formation of clathrate hydrates of these gases. At the same hydrostatic gas phase pressure, the CO2–water interface has a lower interfacial tension than the CH4–water interface. A greater number of CO2 molecules, as much as three times more than methane at the same pressure, were adsorbed at the interfacial layer, which reflects the stronger electrostatic quadrupolar and van der Waals interactions between CO2 and water molecules at the interface. The water surfaces are covered by less than a monolayer of gas even when the pressure of the system goes near the saturation pressure of CO2. The surface adsorbed molecules are in dynamic equilibrium with the bulk gas and with exchange between the gas and interface regions occurring repeatedly within the timescale of the simulations. The effects of the changes in the CO2–water interfacial tension with external temperature and pressure conditions on the formation of the clathrate hydrates and other CO2 capture and sequestration processes are discussed.

Addressing the sensitivity of signals from solid/liquid ambient pressure XPS (APXPS) measurement
by Jin Qian
The Journal of Chemical Physics, Volume 153, Issue 4, July 2020.
Ambient pressure XPS has demonstrated its great potential in probing the solid/liquid interface, which is a central piece in electrocatalytic, corrosion, and energy storage systems. Despite the advantage of ambient pressure XPS being a surface sensitive characterization technique, the ability of differentiating the surface adsorbed species (∼Å scale) and bulk electrolyte (∼10 nm scale) in the spectrum depends on the delicate balance between bulk solution concentration (C), surface coverage (θ), bulk liquid layer thickness (L), and inelastic mean free path (λ) as a function of photon energy. By investigating a model system of gold dissolving in a bromide solution, the connection between theoretical prediction at the atomic resolution and macroscopic observable spectrum is established.

Inertial effects on trapped active matter
by Luis L. Gutierrez-Martinez
The Journal of Chemical Physics, Volume 153, Issue 4, July 2020.
In this work, the dynamics of inertial (mass and moment of inertia) active Brownian particles trapped in a harmonic well is studied. This scenario has seen success when characterizing soft passive and active overdamped matter. Motivated by the variety of applications of this system, we analytically find the effect of translational and rotational inertia on the mean-square displacement (MSD), mean-square speed (MSS), swim, Reynolds, and total pressures of a system of inertial active Brownian particles subject to a weak and a strong harmonic trap. Following a Langevin formalism, we explicitly find that as inertia grows, the systems’ MSD and total pressure are enhanced, but its MSS and swim pressure decrease. The use of Langevin dynamics simulations enables us to observe that as inertia grows, inertial active matter under a strong trap no longer “condensates” at the “border” of the trap, but it rather tends to uniformly spread in space. Our analytical results are also numerically validated.

First-principles prediction of two-dimensional copper borides
by Xiao-Ji Weng, Xin-Ling He, Jing-Yu Hou, Chun-Mei Hao, Xiao Dong, Guoying Gao, Yongjun Tian, Bo Xu, and Xiang-Feng Zhou
Author(s): Xiao-Ji Weng, Xin-Ling He, Jing-Yu Hou, Chun-Mei Hao, Xiao Dong, Guoying Gao, Yongjun Tian, Bo Xu, and Xiang-Feng Zhou

Ordered borides of group IB and IIB metals (Cu, Ag, Au, Zn, Cd, Hg), as the well-known immiscible materials, are practically unknown due to the small electronegativity difference and large mismatch in their atomic sizes. Nevertheless, such rule may be broken under extreme conditions, i.e., high pressure or low dimensionality. Here two-dimensional (2D) copper borides were predicted from ab initio evolutionary searches, identifying that two structures are metallic whereas another one is strikingly a nodal line semimetal. These results challenge the long lasting puzzle in the immiscible systems and add new members to the 2D materials.
