Modelling the onset and evolution of immiscible viscous fingering in porous media

This paper investigates the physical mechanisms and modelling requirements for accurately simulating the onset and evolution of immiscible viscous fingering in porous media at high viscosity ratios, demonstrating that matching experimental finger scales and saturation patterns necessitates a multi-step approach involving linear stability analysis, the selection of a sufficiently small initial unstable wavelength to account for nonlinear merging, the inclusion of small-scale channelling effects, and a weakly oil-wet capillary pressure function.

Revealing rearrangement of local short-range order in metastable liquid metal under static magnetic field

Using in situ high-energy X-ray scattering and GAP-assisted modeling, this study reveals that a static magnetic field induces bond distortion and symmetry breaking in eutectic Ga-In liquid metal, lowering energy barriers between metastable configurations and offering an atomic-scale mechanism for magnetic field-assisted structural regulation.

Influence of surface nanoroughness on the wave field in an anisotropic half-plane with a nanoinclusion

This study presents a novel frequency-domain Boundary Element Method formulation that integrates continuum mechanics and surface elasticity theory to numerically investigate how surface nanoroughness and material anisotropy influence wave scattering and stress concentrations in an anisotropic half-plane containing an embedded nanoinclusion under P-wave excitation.

Assessments of Radiological Risks in the Buildings and Surroundings of Federal University Wukari (FUW) Campus, Taraba State, Nigeria

This study assesses the radiological risks of the Federal University Wukari campus in Nigeria by measuring indoor and outdoor terrestrial radionuclide concentrations, finding that while current hazard levels are generally low, buildings with poor ventilation and ground-floor locations exhibit higher radiation levels, suggesting that future campus construction should prioritize upper floors with excellent ventilation.

Solid-Phase Lithium Concentration Distribution and Average State of Charge Evolution in Blended Cathodes of Lithium-Ion Batteries Under a One-Dimensional Isothermal Model

This study employs a 1D isothermal COMSOL model with an "additional porous electrode" framework to reveal that blended cathodes exhibit non-monotonic kinetic behavior driven by open-circuit potential overlap, identifying intermediate NMC811 ratios as kinetically limited while terminal ratios offer synergistic optimization for electrode design.

Shape-induced alignment and voltage-controlled switching in cholesteric droplets for smart film applications

This study demonstrates that geometrically flattening cholesteric droplets within polymer films creates large, uniform toroidal director fields that enable reversible, voltage-controlled electro-optical switching with distinct pathways depending on the material's dielectric anisotropy.

Conductive Suppression of Piezoelectric Electromechanical Conversion in Fault-Zone Media

This paper extends a one-dimensional piezoelectric model to include finite electrical conductivity, demonstrating that while the mechanical wave branch remains largely unaffected, the associated electric-field amplitude is significantly suppressed by Ohmic dissipation, thereby establishing a critical conductivity threshold that determines the viability of piezoelectric electromagnetic signals in fault-zone media.

Monolithic kinetic algorithm for heterogeneous porous media systems using a continuous one-domain approach

This paper proposes a monolithic lattice Boltzmann model that utilizes a continuous one-domain approach to accurately simulate weakly compressible, isothermal flows in heterogeneous porous media by recovering generalized volume-averaged equations with correct porosity scaling, Galilean invariance, and enhanced numerical stability for device-scale design applications.
