Mitochondrial Protection and Neural Repair via ROS‐Responsive Biomimetic Nanoparticles in Intracerebral Hemorrhage

Advanced Science, EarlyView.
A ROS‐responsive biomimetic nanoparticle platform co‐delivers DIDS and Mdivi‐1 to protect mitochondria and promote neural repair after intracerebral hemorrhage. By targeting LPAR1/VDAC1‐related mitochondrial dysfunction, the nanotherapy reduces oxidative injury, neuronal apoptosis, and blood‐brain barrier disruption, improving neurological recovery and

Unlocking the Full Potential of Jumping Condensation on Microstructured Surfaces

Advanced Science, EarlyView.
Microcone arrays exhibit a spacing‐dependent transition between jumping and non‐jumping condensation. Dense microstructures favor full Cassie droplets, which depart cleanly, while wider spacing favors partial Cassie droplets that retain a localized wet region initiating new nucleation. These findings establish a link between microdroplet morphology and

Habitat‐Specific Design Strategies for Untethered Soft Robots

Advanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Water‐Coupled Interfacial Modulation Enhances Photovoltaic and Pyroelectric Responses in Transparent Self‐Powered ZnO/NiO Photodetectors

Advanced Science, EarlyView.
Direct water contact enhances the performance of a transparent self‐powered FTO/ZnO/NiO/AgNW/ZnO UV photodetector. Reduced surface reflection improves optical transmission, while an electric double layer at the ZnO/water interface modulates interfacial electrostatics and promotes charge separation.
