Acoustic Analogy of Quantum Baldin Sum Rule for Optimal Causal Scattering

This paper derives a universal acoustic sum rule analogous to the quantum Baldin sum rule, demonstrating that the integral of the extinction cross-section is fundamentally constrained by a scatterer's static effective mass and stiffness, thereby establishing a theoretical framework for optimizing the transmission loss bandwidth of passive metamaterials.

Dislocation-ledge coupling governs semicoherent precipitate growth

This study resolves the kinetic mechanism of semicoherent precipitate growth by demonstrating that lath morphology is governed by the coupling of diffusion-enabled dislocation network reorganization with nanoscale ledge sweeps, a finding validated through phase-field-crystal simulations and in situ transmission electron microscopy.

Correlative Microstructural Analysis of a Weathered Nantan Meteorite Fragment

This study employs correlative microstructural and compositional analysis to reveal that the weathering of a Nantan meteorite fragment produces a magnetite-rich matrix with distinct grain size variations linked to nickel content, alongside various iron-nickel oxides and carbonates formed through the aqueous alteration of kamacite and direct oxidation of Fe-Ni metal.

Configuration-dependent electronic and optical properties of 2D Mo1x_{1-x}Wx_xS2_2 alloys across the full composition range

This study reveals that while the structural stability of 2D Mo1x_{1-x}Wx_xS2_2 alloys is primarily composition-driven, their electronic and optical properties, including band-edge splitting, valley energetics, and optical selection rules, are critically governed by the specific microscopic arrangement of atoms across the full composition range.
