Thermal Annealing Enhances Piezoelectricity and Regenerative Potential of PVDF‐TrFE Nanofiber Scaffolds

open access: yesAdvanced Materials Technologies, EarlyView.
Thermal annealing improves the structure, stiffness, and piezoelectric properties of poly(vinylidene flouride‐trifluoroethylene) (PVDF‐TrFE) nanofiber scaffolds. These annealed scaffolds promote Schwann cell proliferation and matrix remodeling in vitro and demonstrate in vivo biocompatibility.

RRFL: A rational and reliable federated learning incentive framework for mobile crowdsensing

open access: yesJournal of King Saud University: Computer and Information Sciences
The data privacy concern for mobile users (MUs) in mobile crowdsensing (MCS) has attracted significant attention. Federated Learning (FL) breaks down data silos, enabling MUs to train locally without revealing actual information.

Multi‐Level Hybrid Anti‐Counterfeit Labels via Solid‐State Dewetting Under Spatial Confinement

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a hybrid encoding approach combining deterministic patterns fabricated by photolithography and stochastic features formed by the solid‐state dewetting of silver films under strong confinement at the micrometer and nanometer length scales.
