Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers

Advanced Functional Materials, EarlyView.
Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

Alginate‐Sludge Derived Biochar‐Calcium Hydrogel for Phosphate Removal and Slow‐Release Fertilizer: A Sustainable and Multifunctional Solution

Advanced Functional Materials, EarlyView.
An alginate‐based biochar hydrogel (ABC‐hydrogel), derived from sewage sludge, is developed for simultaneous phosphate removal and agricultural reuse. It captures phosphorus from water and gradually releases it as fertilizer, enhancing lettuce growth.

Dynamically Adaptive Wrinkle‐Structured Light‐Regulating Films for Energy‐Efficient Buildings

Advanced Functional Materials, EarlyView.
A scalable, moisture‐responsive cellulose nanofibril/polyvinyl alcohol (CNF/PVA)‐glycerol film with switchable wrinkled surfaces for dynamic light regulation is developed. Compared to glass, it achieves tunable light diffusion for daylight harvesting, thermal regulation, and privacy control.

High Dynamic Range Thin‐Film Resistive Flow Sensors for Monitoring Diverse Biofluids

Advanced Functional Materials, EarlyView.
Thin‐film resistive flow sensors with thermoresistive and piezoresistive mechanisms are developed for biofluid monitoring. Fabricated using biocompatible materials and laser micromachining, the devices achieve sub‐millimeter dimensions and a broad dynamic range.
