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 ...

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.

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.
