Multi‐Interface Polarization Modulation in Cu@TiO 2 @MgO/PVDF for Enhanced Dielectric Constant and Breakdown Performances

ABSTRACT Decoupling control and collaborative improvement in both dielectric constant ( ε ) and breakdown strength ( E b ) while holding low loss of polymeric composites, constitutes a challenge for power electronics and energy storage systems. To realize this objective in copper...

Geometrically Matched Bridge Adsorption: Boosting Polysulfide Conversion Kinetics via Fe 2 N 6 Catalysts

ABSTRACT The commercialization of lithium–sulfur batteries (LSBs) is hindered by sluggish lithium polysulfides (LiPSs) conversion kinetics. While single‐atom catalysts (SACs) are widely used, their rigid coordination often causes severe “geometric mismatches” with LiPSs, leading...

Governance disclosure regimes and investor confidence: evaluating comply-or-explain mechanisms in African capital markets

Purpose This study aims to investigate how governance disclosure regimes, particularly comply-or-explain mechanisms, affect investor confidence across African capital markets. Focusing on South Africa, Nigeria and Egypt, it examines whether high-quality governance disclosures enh...

A multi-channel signal-enhanced fractional-order vibrational resonance coupled stochastic resonance array method for early fault detection of rolling bearings

In the field of early fault detection for rolling bearings, stochastic resonance (SR) and vibrational resonance (VR) have been widely adopted as effective nonlinear signal processing tools. Nonetheless, when it comes to enhancing weak fault characteristics, most existing methods...

Decoupling Ion–Dipole Interactions via Competitive Coordination for Durable Dendrite-Free Zinc Metal Batteries

Abstract The aqueous zinc metal batteries (AZMBs) are famous for high-safety and high-energy-density, but limited by severe challenges around the Helmholtz plane layer such as the strong ion–dipole interactions between Zn 2+ and H 2 O, resulting in slow desolvation processes and...

Influence of substrate heating for microstructure and physical properties of Cu-Al-O thin film

We prepared Cu-Al-O thin films on silicon and quartz substrate by direct current (DC) reactive magnetron sputtering method. The substrate temperatures varied at room temperature (~25℃) and 200℃ with post-annealed at 900℃ in argon atmosphere for 3h. The results indicate that the f...

Image Inpainting in 30 Years: A Survey

ABSTRACT As a fundamental task in restoring continuous visual signals, image inpainting plays a critical role in autonomous driving perception, medical imaging, video editing and digital heritage preservation. Driven by deep learning and large‐scale generative models, the field h...
