Ambient‐Dried MOF/Cellulose‐Based Aerogels for Atmospheric Water Harvesting and Sustainable Water Management in Agriculture

open access: yesAdvanced Functional Materials, EarlyView.
Ambient‐dried composite aerogels integrating MOF‐303, TEMPO‐oxidized cellulose nanofibers (TOCNF), and hygroscopic salts enable high‐performance atmospheric water harvesting (AWH), achieving competitive uptake at both low and high humidity. Enhanced with a solar‐evaporation layer, these scalable aerogels support self‐sustained plant growth in a ...

Dual‐Nanoparticle Engineered Hydrogel Reverses Bicellular Oxidative Stress to Accelerate Diabetic Fracture Healing

open access: yesAdvanced Functional Materials, EarlyView.
CD105‐LNPs and PS‐LNPs can deliver α‐lipoic acid to bone marrow mesenchymal stem cells and bone marrow‐derived macrophages, reversing high glucose‐induced oxidative stress while enhancing osteogenesis and M2 polarization. Integrating both nanoparticles into glucose‐responsive hyaluronic acid hydrogel forms DLNPs@HA hydrogel, which accelerates diabetic ...

Highly Scalable, Raspberry‐Like Microbeads with Nano‐/Micro‐Confined Hybrid Hydrogel Desiccants for Rapid Atmospheric Water Harvesting

open access: yesAdvanced Functional Materials, EarlyView.
A scalable nano‐/micro‐confinement strategy is developed, where polyacrylamide (PAM)‐LiCl hybrid desiccants are confined within hollow nanoparticles (HNPs) and assembled into raspberry‐like microbeads. The beads have a hydrogel‐rich core and an NP‐rich shell for fast absorption and desorption, releasing water 13.6 L kg⁻¹ day⁻¹.

Covalent Adaptable Networks with Associative Siloxane Exchange Enabled by Amide‐Based Internal Catalysis: Designing for Reprocessability and Extrudability by Increasing the Cross‐Link Density

open access: yesAdvanced Functional Materials, EarlyView.
Internally catalyzed siloxane dynamic chemistry is demonstrated resulting from amides covalently linked through alkyl chains to siloxanes. The alkyl length in the siloxane‐containing monomer tunes the network cross‐link density. Siloxane exchange dynamics are faster with increasing cross‐link density, because associative exchange is second order in ...

Graft Copolymer‐Stabilized Liquid Metal Nanoparticles for Lithium‐Ion Battery Self‐Healing Anodes

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a self‐healing liquid metal anode for lithium‐ion batteries, where graft copolymer‐stabilized eutectic gallium indium (EGaIn) nanoparticles enhance stability and rate performance. The fluorinated grafted copolymer forms ionic channels, preventing EGaIn aggregation and facilitating lithium‐ion migration.
