The damage and failure mechanism of prestatically loaded rock during medium‐strain rate cyclic impact loading

Deep Underground Science and Engineering, EarlyView.
Based on experimental results and theoretical analysis, an established rock damage accumulation model that comprehensively considers the preapplied static load, impact peak value, impact frequency, and impact times. Abstract To study the rock damage mechanism under high static loading and superimposed medium strain rate cyclic impact loading, a series ...

No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.

Effect of Hydrotreating Severity on Jet Fuel Thermal Oxidation Stability of Olefinic Synthetic Kerosene

Energy Science &Engineering, EarlyView.
The extent of hydrotreating that is required for olefinic kerosene to pass the jet fuel thermal oxidative stability test was investigated. Fouling species are destroyed after mild hydrotreating, and no further benefit is derived from more severe hydrotreating.

Performance Assessment of the Immersed Boundary Method in the Framework of the Moment Representation Lattice Boltzmann Method

International Journal for Numerical Methods in Fluids, EarlyView.
The immersed boundary method (IBM) was coupled with the moment representation lattice Boltzmann method (MR‐LBM), reducing bandwidth requirements compared to population‐based LBM formulations. A systematic assessment of IBM parameters was conducted to quantify their effect on computational performance.
