Dancing Electrohydrodynamic Tip Streaming Modulated by Faraday Instability

Advanced Science, EarlyView.
A novel dancing electrospray phenomenon is reported characterized by high‐frequency, robust, and multi‐directional alternating ejection modes. This phenomenon arises from the electrohydrodynamic (EHD) tip streaming at the crests of Faraday waves excited on the liquid meniscus, and it offers significant advantages in high‐throughput and multi‐path ...

Laser‐Engraved Micro‐Patterned rGO/WPU Composite Structures for Aircraft Applications: Synchronizing Electrothermal De‐Icing and Broadband Microwave Transparency

Advanced Science, EarlyView.
While conventional electrothermal materials tend to reflect electromagnetic waves during de‐icing. Inspired by the frequency‐selective surface theory, this paper designs NJPS for rGO/WPU electrothermal coatings based on the traditional Jerusalem structure.

MUC15 Ectodomain Architecture Regulates Integrin Clustering to Control Cancer Metastasis

Advanced Science, EarlyView.
This study uncovers a size‐dependent adhesion paradigm, demonstrating that the glycocalyx protein MUC15 suppresses pancreatic cancer progression by attenuating integrin activation, focal adhesion assembly, and YAP mechanotransduction. Integrating computational modeling and experimental validation, the work reveals a mechanical mechanism by which MUC15 ...
