Triboelectric–Electromagnetic Generator‐Enabled Hybrid Power Backpack for Self‐Powered Field Safety Management

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A lightweight hybrid backpack integrating SC‐TENGs and R‐EMGs harvests biomechanical energy during walking. With a low activation speed of 3 km h−1 and a high specific power of 0.18 W kg−1, it enables self‐powered field safety management. The power backpack refers to an energy‐harvesting solution engineered to mitigate battery reliance in wearable ...

Resveratrol Ameliorates Allergic Rhinitis by Activating SIRT1 to Disrupt the Mitochondrial ROS‐Inflammation Vicious Cycle

open access: yesFlavour and Fragrance Journal, EarlyView.
This study demonstrates that resveratrol alleviates allergic rhinitis by activating SIRT1, thereby disrupting the mitochondrial ROS‐inflammatory cycle, improving mitochondrial function, promoting anti‐inflammatory M2 macrophage polarisation, and reducing epithelial oxidative damage.
