Engineering Triboelectric Paper for Energy Harvesting and Smart Sensing

open access: yesAdvanced Materials, EarlyView.
Engineering nano‐graphite coated paper (NG@P) is produced to serve as triboelectric layers and electrodes for TENGs. Ultra‐high power density above 14 kW m−2 is achieved due to the electrostatic discharge on the surface. Moreover, smart home sensors are fabricated using the NG@P for motion sensing and sleep monitoring, which could be used for security ...

CO2‐Responsive Smart Wood Scaffold for Natural Organic Matter Removal without Secondary Pollution

open access: yesAdvanced Materials, EarlyView.
A CO2‐responsive smart wood scaffold is developed for sustainable water purification, achieving efficient natural organic matter (NOM) removal and microbial disinfection without secondary pollution. The CO2‐responsive polymer coating undergoes protonation upon CO2 exposure, enabling strong cation−π interactions with NOM.
