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.

Atmospheric Doping of Stretchable Polymer Semiconductors for Skin Electronics
An atmospheric doping system using oxygen molecules in air as dopants is introduced for stretchable polymer semiconductors. The chemisorbed oxygen molecules act as acceptor, lead to increase not only the hole concentration of the semiconductor film over two orders of magnitude (3.37 × 1017 cm−3) but also electrical properties of the field‐effect ...

Chemo‐Mechanical Coupling in Hydrogels: Dynamics in the Diffusion‐Limited Regime
A time‐dependent continuum model is developed to capture the transient swelling dynamics of chemo‐mechanical hydrogels. By coupling chemical reactions, solvent transport, and polymer deformation, volume phase transitions, reaction kinetics, and transient mechanical instabilities are analyzed.
