Polydopamine‐Wool Textiles for Sustainable Interfacial Solar Vapor Generation

open access: yesAdvanced Science, EarlyView.
A natural wool textile engineered for high solar absorbance and a fast‐wicking structure serves as a highly efficient, single‐layer system for interfacial solar vapor generation (ISVG). This integrated evaporator seamlessly couples rapid water transport with continuous evaporation. Ultimately, this sustainable photothermal design offers a scalable, eco‐

Circadian‐Inspired Hydrogel Moisture Electricity Generation

open access: yesAdvanced Science, EarlyView.
A circadian‐inspired hydrogel moisture‐electric generator enables sustainable electricity generation by autonomously current direction switching between daytime and nighttime. This reversible output is accompanied by inversion of the internal water gradient, which effectively reduce hydrogel fatigue and offers a new strategy for harvesting diurnal ...

A Scalable Double‐Sided Wet Etching Strategy for Large‐Area Mushroom‐Shaped Bionic Adhesives

open access: yesAdvanced Science, EarlyView.
This work presents a scalable manufacturing strategy for high‐performance, large‐area, mushroom‐shaped bio‐inspired adhesives. Using a double‐sided wet etching process, the complex 3D metal molds are fabricated rapidly and controllably. The resulting adhesive structures exhibit strong, stable adhesion under various conditions, including atmosphere and ...
