This study demonstrates that integrating local cooking practices into physics instruction in Nigerian secondary schools significantly enhances students' conceptual understanding of heat transfer, boosts engagement, and promotes gender equity by leveraging culturally familiar, constructivist learning environments.
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.
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.
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.
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.
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.
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.
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.
This paper proposes a hybrid spectral-geometric neural architecture that combines convolutional networks with spectral methods and physics-informed constraints to achieve a 414.9x acceleration in 2D fluid simulations over traditional solvers while maintaining high physical accuracy on complex, irregular boundaries.
This study demonstrates a robust method for fabricating high-purity, high-fidelity 3D ferromagnetic iron nanostructures by combining dwell-time simulation-assisted calibration for precise growth control with plasma-based post-deposition purification to achieve over 80% iron content.
