Advent of Pulsed Field Ablation for Atrial Fibrillation: State-of-the-Art Review

Reviews in Cardiovascular Medicine
Pulsed field ablation (PFA) is a novel ablation technique for atrial fibrillation (AF). Indeed, PFA utilizes cell electroporation and exhibits selectivity for myocardial tissue, depending on the method used to deliver the pulsed electric field ...

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.

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

Advanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Simultaneous Enhancement of Performance and Stability in Dual‐Gate a‐IGZO Thin‐Film Transistors via Single‐Step Laser Annealing for Capacitor‐Less DRAM

Advanced Functional Materials, EarlyView.
A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.
