Sub‐Nanometer Ferroelectric Tunnel Junctions With Record‐High on‐Current Density Through Synergistic Microwave Annealing and High‐Field Activation

Small, EarlyView.
ABSTRACT High‐density memory systems require a high on‐state current density (Jon) to ensure fast read speeds and large sensing margins in cross‐point array applications. However, achieving high Jon in atomically thin ferroelectric tunnel junctions (FTJs) remains an unmet challenge, hindered by parasitic interfacial layer (IL), depolarization fields ...

Gelatin Nanosphere‐Decorated 3D Aramid Nanofiber Hybrid Nanoporous Separators with Regulated Ion Transport for Li‐Metal Batteries

Small, EarlyView.
Gelatin nanosphere‐decorated aramid nanofiber hybrid nanoporous separators with high porosity are fabricated via a phase separation‐induced self‐assembly method. This separator enhances cation transport and regulates ion distribution, enabling the formation of a stable solid electrolyte interphase layer and suppression of Li dendrite growth.

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Investigation of the Simplified Equivalent Circuit Model of the Post‐Arc Sheath Stage in DC Vacuum Circuit Breakers

High Voltage, EarlyView.
ABSTRACT This paper presents a simplified equivalent circuit model (ECM) for the post‐arc sheath stage in DC vacuum circuit breakers and outlines the method for calculating circuit parameters using the particle‐in‐cell Monte Carlo collision (PIC‐MCC) method. The post‐arc sheath is modelled as a parallel combination of a variable resistor and a variable
