Multifunctional Carbon Dots for Electrochemical Capacitors Reviewed: Their Opportunities and Challenges

open access: yesAdvanced Science, EarlyView.
Carbon dots (CDs) with unique natures of small size, high specific surface area, and tunable surface functional groups significantly enhance the specific capacitance and cycling stability of electrochemical capacitors (ECs). This review systematically discusses critical challenges and opportunities associated with multifunctional CDs in ECs, aiming to ...

Photocatalytic Activity of Ionic Carbon Nitrides is Governed by Cation‐Modulated Dark Exciton Dynamics

open access: yesAdvanced Science, EarlyView.
This study establishes a direct link between photocatalytic activity, spectroscopic properties, and theoretical analysis of structural effects on exciton behavior in ionic carbon nitrides with different cations. The exciton lifetimes and photocatalytic activity are shown to be primarily related to different dark exciton dynamics governed by changes in ...

Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

open access: yesAdvanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Dynamic Mosaicity Modulates Ion Transport in Stimuli‐Responsive Liquid Crystal Electrolytes

open access: yesAdvanced Science, EarlyView.
Thermotropic ionic liquid crystals provide a tunable platform for dimensionally‐controlled soft electrolytes, where anisotropy, nanoconfinement, and dynamic mosaicity govern ion transport behavior. In situ and operando analyses reveal a direct correlation between dynamic mosaicity and mesoscopic conductivity.
