Observation of Shortwave Fadeout Events Using Chinese Dual Auroral Radar Network (CN‐DARN) During the Severe Solar Storm in May 2024

Space Weather
Shortwave fadeout (SWF) is a typical dayside high‐frequency radio disturbance caused by solar flare‐induced ionospheric ionization enhancement. Using newly built Chinese Dual Auroral Radar Network (CN‐DARN) observations, we investigate two X‐flare‐driven

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Spatially Regulated Silicon Clusters in Trimodal Composite Anodes for High‐Energy Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A trimodal anode architecture spatially regulates silicon clusters within confined interstitial environments formed by graphite and contorted hexabenzocoronene. This confinement suppresses silicon aggregation and localized stress while enabling efficient Li‐ion transport, achieving high‐capacity, stable lithium‐ion batteries.
