The current paper focuses on high-pressure reservoirs and the consequences of their potential burst,related to scenarios of thermal or mechanical aggressions, in tunnels.CFD (Computational Fluid Dynamics) modeling can be used to account for the effects of suchscenarios. An intrinsic advantage of such an approach consists in integrating the specific...

The properties of YMg in B2 structure have been comprehensively analysed using the first-principles plane-wave pseudopotential method. Specifically, the structural, electronic, elastic, vibrational, and optical properties were investigated using the generalized gradient approximation (GGA) method in the context of density functional theory. The Vie...

Since the discovery of type-II Dirac semimetal (DSM) as the potential candidate for topological superconductor, magneto-transport studies on diverse type-II DSMs have been of tremendous research interest. Here we report the structural and magneto-transport properties of type-II DSM candidate Ir2In8S under high pressure. With increasing pressure, th...

Luminescent semiconductor nanocrystals are a fascinating class of materials because of their size-dependent emissions. Numerous past studies have demonstrated that semiconductor nanoparticles with radii smaller than their Bohr radius experience quantum confinement and thus size-dependent emissions. Exerting pressure on these nanoparticles represent...
The formation of boron carbide under high pressures and from elemental reactants has been studied and optimum parameters have been determined by varying the (P, T, reactants) conditions. To this end, stoichiometric mixtures of commercial beta rhombohedral boron and amorphous glassy carbon have been subjected to temperatures ranging from 1473 K to 2...
This article investigates the effects of increasing pressure up to 4 atm on radiative heat transfer in momentum-driven methane turbulent jet flames by using well-established chemical mechanism, combustion, soot production and radiation models. A transported PDF method is used to close properly the soot-production turbulence interaction and the emis...

Despite their apex predator role, relatively little is known about the foraging strategies that deep-diving marine mammals employ to target prey resources available at different depths with different costs of access. Using hidden Markov model (HMM) analysis of behavioral time series, we aimed to quantify the potential for multiple foraging strategi...

External pressure applied to a solid material causes modifications of the bonding which can provide a chemical explanations of phase transitions. The behaviour of the Electron Localization Function (ELF) has been examined for the body-centred cubic, face-centred cubic and I4̄3d−16\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysy...
The 5 K superconductor La2Sb shares some structural similarities with the iron-pnictides and -chalgogenides, especially the so-called 122-compounds, despite lacking a 3d-metal component. In order to look for similarities and dissimilarities of this layered metal pnictide with the higher- Tc Fe-based superconductors, we have performed a combined exp...
