Nucleophilic Gallyl Anions Enable Ga─Au Bimetallic Ammonia Activation

open access: yesAngewandte Chemie, EarlyView.
Unlocking gallyl nucleophiles: Counterion control enables formation of an unsupported gallyl─gold complex. Gold coordination induces a polarity switch at gallium, enabling cooperative activation of NH3 and related N─H/O─H substrates under mild conditions.

Piezoelectric Nanocomposite Hydrogel for Wireless Neural Stimulation and Tissue Augmentation

open access: yesAdvanced NanoBiomed Research, EarlyView.
A cell/tissue supporting piezoelectric hydrogel system (PZ‐gel) that incorporates ferroelectric, pyroelectric, and piezoelectric ceramic material barium titanate into an alginate/carboxymethyl chitosan hydrogel. The PZ‐gel can be sonoactivated for wireless neural cell and tissue stimulation, with the potential to be used as a stimulatory cell substrate

Interfacial Defect Engineering for Enhanced Polymer Solar Cell Performance

open access: yesJournal of Applied Polymer Science, EarlyView.
Plasmonic is an effective mechanism to improve the charge transport process in polymer solar cells. Numerical simulation confirms the effect of multiple enhancement mechanisms of plasmonic in PTB7:PC70BM‐based solar cells. ABSTRACT Plasmonic metal nanoparticles provide a promising strategy to simultaneously modulate optical absorption and charge ...
