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.

Lateral Epitaxy Suppresses Self-Trapped Excitons in 2D perovskites

This study demonstrates that constructing lateral epitaxial heterostructures between PEA2PbCl4 and Sn-alloyed PEA2Pb1-xSnxBr4 suppresses self-trapped exciton emission and significantly enhances carrier mobility by mechanically stabilizing the lattice and facilitating efficient interfacial energy transfer.

A Reproducible Workflow for Extracting Quantum Hamiltonians from Surface-Adsorbate Models

This paper presents an open-source, reproducible workflow that bridges density functional theory surface models and quantum algorithms by automatically extracting hydrogen-capped clusters, selecting active spaces, and constructing validated fermionic and qubit Hamiltonians for surface-catalysis systems like IrO2(110) without requiring high-performance computing.

Higher-Order Photon Correlation Imaging with Single-Photon Detector Arrays Enables Noise-Blind Source Separation

This paper presents a noise-blind source separation technique for space-based faint target detection that utilizes a random dynamic mask modulation scheme to generate super-bunching light and achieve higher-order photon correlation imaging with single-photon detector arrays, enabling ultra-wide dynamic range, high-speed imaging even under extreme background noise and photon-starved conditions.

Existence Equilibrium: A Universal Mass–Lifetime Scaling Law Derived from 11-Dimensional Rotational Geometry

This paper proposes a zero-parameter scaling law derived from 11-dimensional M-theory geometry that successfully predicts particle masses and lifetimes across the Standard Model by defining a universal "existence budget" governed by topological constraints and a quantized discrete choice, thereby offering indirect evidence for G2-compactified M-theory.

Framework-stabilized multistage transition in antiferroelectric ceramics for high-energy storage

This paper demonstrates that stabilizing a PbZrO₃-derived antiferroelectric framework combined with microstructural engineering enables multistage polarization switching in ceramics, achieving ultrahigh recoverable energy density (15.2 J cm⁻³), high efficiency, and exceptional thermal stability for high-power pulsed power applications.
