Heat Delivery Accompanying Pulsed Field Ablation

Journal of Theoretical Biology
Pulsed Field Ablation (PFA) is a technique to achieve pulmonary vein isolation, alternative to the traditional thermal ablation procedures. Instead of delivering or subtracting heat, PFA uses rapid pulses of a high intensity electric field, inducing cells electroporation.

Hydrogen‐Bond–Driven Ion Retention in Electrolyte‐Gated Synaptic Transistors

Advanced Functional Materials, EarlyView.
Anion molecular design governs ion–polymer interactions in electrolyte‐gated synaptic transistors. Asymmetric anions induce hydrogen‐bond interactions that suppress ion back‐diffusion and stabilize doping, enabling enhanced nonvolatile synaptic properties.
