Pulsed-field ablation versus cryoballoon ablation in patients with persistent atrial fibrillation

International Journal of Cardiology: Heart & Vasculature
Background: Current thermal energy sources such as cryoballoon (Cryo) ablation technology are associated with high rates of reconnected pulmonary veins (PV), especially in patients with persistent atrial fibrillation (AF). Pulsed-field ablation (PFA) may

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

Advanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Bio‐Inspired Artificial Ionic Mechanoreceptor

Advanced Functional Materials, EarlyView.
A skin‐inspired artificial mechanoreceptor based on ionic interactions is presented for biomimetic tactile sensing. Pressure‐driven ionic redistribution within microfluidic channels generates a self‐powered electrical signal without external bias. The generated waveform exhibits mechanoreceptor‐like temporal features, including overshoot and undershoot,

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

Advanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.
