Probabilistic characterization of seepage‐induced tunnel face failure via a two‐phase double‐point material point method

Deep Underground Science and Engineering, EarlyView.
To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Charting Water‐in‐Natural‐Salt (WiNS) Electrolytes. Part I: Effect of Anion's Alkyl Tail Length

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
At 20 m, potassium carboxylates from formate to butyrate reveal anion tail‐controlled nanostructure. SAXS shows a pre‐peak shifting to lower q with chain length. Molecular dynamics reproduces S(q) and attributes it to concentration fluctuations forming bicontinuous segregation.

Effects of hybrid metal oxide nanoparticles on the tribological and emission attributes of algae‐derived biofuel in compression ignition engines

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The growing demand for sustainable fuels has accelerated the development of algae‐derived biodiesel for compression‐ignition engines. In this study, Chlorella vulgaris methyl ester (AME) exhibited physicochemical properties comparable to diesel and satisfied ASTM D6751 fuel quality requirements, making it suitable for blending.

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Optimization of Blasting‑Induced Roof Cutting Parameters in Key Stratum and Its Application in Gob‑Side Entry Retention Technology

Energy Science &Engineering, EarlyView.
This study addresses hard roof coal seam conditions by optimizing key stratum blasting‐cutting parameters through theoretical analysis, numerical simulation, and field tests. It proposes calculation methods for blast hole spacing and delay timing based on stress wave theory, controlling roadway deformation within 35 mm, thereby enhancing resource ...
