Hydrogel Thermostat Inspired by Photoprotective Foliage Using Latent and Radiative Heat Control

Advanced Materials, EarlyView.
Guided by Populus alba foliage, this hydrogel latent‐radiative thermostat (LRT) actively balances latent and radiative heat fluxes. An LRT switches solar reflectance, maintains high mid‐IR emissivity, and reversibly evaporates/regenerates water, while titanium oxide (TiO2) nanoparticles toughen the film.

Facet‐Selective Electrostatic Assembling of 2D Mxene onto Anisotropic Single‐Crystal Metal Oxides for Enhanced Photocatalysis

Advanced Materials, EarlyView.
Overcoming random aggregation, Facet‐Selective Electrostatic Assembly (FSEA) achieves site‐specific integration of 2D MXenes onto 3D TiO2 supports. This electrostatic assembling creates optimized interface energy junctions that facilitate spatial charge transfer.
