High‐Speed, Maneuverable, and Terrain‐Adaptive Micro‐Robot with Tree Frog‐Inspired Bionic Feet

open access: yesAdvanced Science, EarlyView.
A 7.5 mm micro‐robot integrates tree frog‐inspired bionic feet with an electromagnetic linear motor to achieve high‐speed locomotion, slope climbing, and precise turning. It reaches 39 body lengths per second and ascends 30° slopes. The system demonstrates strong potential for inspection tasks in confined and complex environments, such as micro‐aero ...

Gecko‐Inspired Adhesive for Robotic Grippers with Excellent Ultra‐Low‐Temperature Adhesion Performance

open access: yesAdvanced Science, EarlyView.
Phenyl and vinyl groups are used to modify conventional polydimethylsiloxane (PDMS) to yield poly(methylphenylvinylsiloxane) (PMPVS). PMPVS‐based gecko‐inspired arrays with mushroom tips exhibit superior adhesion strength of 36.7 kPa even at −80 °C, which enhances by 5143% compared to PDMS‐based arrays (0.7 kPa at −70 °C).

Recent Advances in Mediator and Proton Relay Usage in Molecular Catalysis

open access: yesAdvanced Science, EarlyView.
The use of electron–proton transfer mediators, redox mediators, and proton relays in synergy with molecular catalysts in energy‐related small‐molecule and organic transformations is discussed, with a focus on recent advances. Linear free‐energy relationship and catalytic Tafel plots provide a systematic foundation for benchmarking these catalytic ...

Nanozyme‐Integrated Hydrogel Targeting AGEs for Diabetic Osteoarthritis Therapy

open access: yesAdvanced Science, EarlyView.
A nanozyme–integrated hydrogel (PTC‐MP) exhibiting with mild photothermal effects is constructed, and a “3R” (restrain‐restore‐reinforce) strategy is proposed for diabetic osteoarthritis (DOA) treatment based on advanced glycation end products (AGEs) targeting.
