Strain‐based modeling and analysis for rock blasting and geomechanics applications

open access: yesDeep Underground Science and Engineering, EarlyView.
This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

A Note on the Domain of Attraction for the Stationary Solution to a Singularly Perturbed Parabolic Equation

open access: yesМоделирование и анализ информационных систем, 2017
We consider  a boundary-value problem  for a singularly  perturbed parabolic  equation with an initial function  independent of a perturbation parameter in the case where a degenerate stationary equation  has smooth possibly intersecting roots.

Nonsilting transport characteristics of coal slurry in a deep underground fluidization conveying pipeline under the action of a guide vane swirler

open access: yesDeep Underground Science and Engineering, EarlyView.
Aiming at the scientific frontiers of in situ fluidized mining of deep resources, a deep coal fluidized pipeline lifting system based on hydraulic conveying has been proposed. To solve the issue of particle sedimentation of large particles in horizontal connection sections, a solution involving the installation of guide vane‐type swirlers in the ...

Organic Electrolyte Composed of Strongly and Weakly Coordinating Molecules for Sodium‐Ion Battery. A Molecular Dynamics Simulation Study

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Molecular dynamics simulations reveal that the addition of weakly coordinating solvents disrupts stable Na+ solvation with various coordinating configurations, accelerating solvents exchange and promoting Na+ migration. The optimized electrolyte achieves the highest ionic conductivity as well as the fractional ionic conductivity of Na+ of 3.68 ± 0.36 ...

Preparation of Se(IV) Aryltrifluoromethylselenide Dichlorides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
An efficient synthesis of dichloro(aryl)(trifluoromethyl)‐λ4‐selanes via chlorination of aryl trifluoromethylselenides with SO2Cl2 is reported. The compounds were fully characterized and their stability studied. Density functional theory studies reveal an asynchronous concerted, exergonic pathway, while formation of the Se(VI) derivative is both ...

Cytotoxicity of 19 Pesticides in Rainbow Trout Gill, Liver, and Intestinal Cell Lines

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract The rainbow trout gill cell line (RTgill‐W1), via test guideline 249 of the Organisation for Economic Co‐operation and Development, has been established as a promising New Approach Methodology, although to advance confidence in the method more case studies are needed that: 1) expand our understanding of applicability domains (chemicals with ...
