Self‐Sustaining Hybrid Passive Cooler Enabling Highly Effective Thermal Management for Outdoor Electronics

open access: yesAdvanced Science, EarlyView.
An innovative hybrid passive cooler integrates a porous radiative coating and an atmospheric moisture‐harvesting hydrogel within a melamine sponge skeleton, synergizing radiative cooling, sensible‐heat absorption, and latent‐heat evaporation. It maintains an average 8.3°C sub‐ambient cooling under sunlight and a maximum ∼42.4°C drop under 2000 W·m−2 ...

Ferroionic Electrostatic Landscapes Enabling Wireless Energy Harvesting, Storage, and Sensing

open access: yesAdvanced Electronic Materials, EarlyView.
By integrating experiments and electrostatic field simulations, we show that long‐range wireless coupling in Li‐based ferroionics devices emerges from the cooperative interaction between ionic migration and electronic polarization. This coupling sustains self‐polarized electrostatic fields across centimeter‐scale air gaps without external bias or ...
