Resolving the aragonite (CaCO3) superstructure paradox

This study resolves the long-standing aragonite superstructure paradox by demonstrating that mysterious symmetry-forbidden reflections, previously mistaken for new CaCO3 polytypes, are actually diffraction artifacts caused by nanoscale polysynthetic twinning, a finding validated through modeling and experiments that offers a generalized framework for identifying similar artifacts in other twinned materials.

Beyond Single-Copy Quantum Measurements: Ensemble Structure Enables Basis Discrimination

This paper demonstrates that while ensembles of qubits prepared in either the computational or Hadamard basis are indistinguishable via single-copy measurements due to identical maximally mixed reduced states, a graph-state protocol leveraging multi-copy statistical correlations can successfully discriminate between these basis families, a result experimentally validated on the IBM Fez quantum processor with high accuracy.

Stability-Based Optimization of Planar Quiet Wind Tunnel Nozzles: Two-Dimensional Design and Three-Dimensional Assessment

This study demonstrates that while two-dimensional stability-based optimization effectively suppresses instabilities on the top wall of planar quiet wind tunnel nozzles, reliable design requires three-dimensional assessment to account for sidewall-induced crossflow disturbances that the planar model fails to capture.

On Geometric Origin of Dark Matter, Dark Energy, and the Fine-Structure Constant

This paper proposes a parameter-free geometric framework where dark matter, dark energy, and the fine-structure constant emerge from the interplay of metric and invariant measures on spacetime, successfully reproducing key cosmological ratios and the value of $\alpha$ without invoking new particles.

Multi-Channel Nanoribbon Arrays for Enhanced Superconductivity in Magic-Angle Graphene

This paper proposes a conceptual framework for enhancing the superconducting critical temperature of magic-angle twisted bilayer graphene by utilizing patterned cobalt nanoribbon arrays to imprint a topological spin texture that suppresses intervalley phonon pair-breaking, supported by computational modeling and five falsifiable experimental predictions.

Theoretical Analysis of the Energy Cascade in Quantum Turbulence: From Richardson–Kolmogorov Eddies to Kelvin Waves

This paper presents a comprehensive theoretical analysis of the energy cascade in quantum turbulence, tracing the transfer of energy from macroscopic Richardson–Kolmogorov eddies through the inter-vortex bottleneck to microscopic Kelvin-wave cascades and dissipation, while examining the roles of vortex reconnection, competing cascade models, and finite-temperature mutual friction effects.

Influence of Bottom Electrode Material on the Morphological and Frequency-Dependent Electrical Characteristics of Sputtered HfO₂ Thin-Film Metal-Insulator-Metal Capacitors

This study demonstrates that the bottom electrode material significantly influences the surface morphology and frequency-dependent electrical performance of RF-sputtered HfO₂ MIM capacitors, with the Al/HfO₂/Pt structure exhibiting superior dielectric properties and lower energy dissipation compared to the Al/HfO₂/Al configuration, making it more suitable for high-frequency RF applications.

Bridging human kidney stone dynamics and damage under shock-wave lithotripsy: synchrotron X-ray imaging and tomography

By combining synchrotron X-ray imaging with high-speed optical techniques, this study reveals that while cavitation drives kidney stone comminution through surface erosion and interlayer bubble collapse, the specific fracture mechanism—ranging from spallation to delamination—is dictated by the stone's microstructure rather than the loading conditions alone.
