We report measurements of excess electron mobility in dense Argon gas at the two temperatures T = 152.15 and 162.30 K, fairly close to the critical one (Tc = 150.7 K), as a function of the gas density N up to 14 atoms·nm−3 (Nc = 8.08 atoms·nm−3). For the first time a maximum of the zero-field density-normalized mobility μ0N has been observed at the same density where it was detected in liquid A...

Shock compression experiments achieving ≥100 GPa pressures are available for seven silicate liquid compositions in the system CaO-MgO-FeO-Al2O3-SiO2. Especially when liquid states have been sampled along multiple Hugoniots, these data are sufficient to evaluate the dependence of Grüneisen γ on volume in silicate liquids. The increase in γ upon compression in these liquids is a surprising featur...

The effect of three-body interactions on the solid-liquid phase boundaries of argon, krypton, and xenon is investigated via a novel technique that combines both nonequilibrium and equilibrium molecular dynamics. The simulations involve the evaluation of two- and three-body forces using accurate two-body and three-body intermolecular potentials. The effect of three-body interactions is to substa...

We investigate the relation between thermodynamic and dynamic properties of an associating lattice gas (ALG) model. The ALG combines a three dimensional lattice gas with particles interacting through a soft core potential and orientational degrees of freedom. From the competition between the directional attractive forces and the soft core potential results two liquid phases, double criticality ...

The density anomaly of liquid Ge(0.15)Te(0.85) measured between 633 and 733 K is investigated with ab initio molecular dynamics calculations at four temperatures and at the corresponding experimental densities. For box sizes ranging from 56 to 112 atoms, an 8 k-points sampling of the Brillouin zone is necessary to obtain reliable results. Contrary to other Ge chalcogenides, no sp(3) hybridizati...

Abstract Densities of two synthetic biomethane-like mixtures were measured in the homogeneous liquid phase and supercritical region using a low-temperature single-sinker magnetic-suspension densimeter. Both consist methane, nitrogen, hydrogen oxygen, whereas second mixture additionally contains carbon dioxide. For first mixture, four isotherms from (100 to 160) K studied over pressure range (1....

Background and objectives: Launaea procumbens is a member of Asteraceae family which can be found in the south part of Iran especially the province of Hormozgan. This plant has got a variety of usage in traditional medicine for curing the skin diseases. In this study, we have investigated the cytotoxic effect of its various extracts at concentrations b...

Comparison of optical power, external quantum efficiency in InGaN / GaN UV LEDs at room temperature and liquid nitrogen is carried out. The spectral densities the current low-frequency noise have been investigated. mechanisms carrier transport, formation noise, dependences rates radiative nonradiative recombination temperatures are considered.

Results are presented from recent density measurements on twenty-nine crystalline ices at temperatures applicable to the outer Solar System and interstellar medium. For each ice we report both a refractive index 670 nm, quantities needed calculate infrared band strengths, complex indices of refraction, and, ultimately, molecular abundances. Comparisons made between densities obtained micrometer...

Abstract The phase structure of baryonic matter is investigated with focus on the role fluctuations beyond mean-field approximation. prototype test case studied chiral nucleon-meson model, added comments quark-meson model. Applications to nuclear include liquid-gas transition. Extensions high baryon densities are performed for both and neutron matter. vacuum systematically explored. It pointed ...
