Accelerating Sono‐Piezoelectric Charge Transport for Antibacterial Therapy and Bone Regeneration by Metal‐Deficient TiO2 Spin‐Polarization Effect

Advanced Science, EarlyView.
The deficient TiO2 (DTO) and Barium titanate (BTO) heterojunction treats osteomyelitis through SDT. The spin‐polarization effect induced by the unpaired spin electrons in Ti atoms can expedite the transfer of ultrasonic piezoelectric charges in BTO, enhancing surface sonocatalytic efficiency.

Protected Chaos in a Topological Lattice

Advanced Science, EarlyView.
Topological and chaotic dynamics are often considered incompatible, with one expected to dominate or disrupt the other. This work reveals that topological localization can persist even under strong chaotic dynamics and, counter‐intuitively, protect chaotic behavior.

Expansion Force‐Based Adaptive Multistage Constant Current Fast Charging with Lithium Plating Detection for Lithium‐Ion Batteries

Advanced Science, EarlyView.
This article presents an adaptive multistage constant current (MCC) charging method for lithium‐ion batteries, using expansion force feedback to detect lithium plating in real time. It outlines how force‐derivative thresholds enable self‐regulation of the charging rate, increasing speed by 50% without damage.

Enhanced Band‐Crystal Engineering Drives Superior Power Generation in GeTe

Advanced Science, EarlyView.
By precisely tuning the band structure and crystal structure in GeTe‐based thermoelectric (TE) materials, this study achieves comprehensive control over electron transport and phonon scattering. Structural optimization significantly enhances carrier‐weighted mobility (µw) while effectively suppressing lattice thermal conductivity (κL), resulting in a ...
