Scalable Polyelectrolyte Complex‐Based Sorbent With Hourly Sorption−Desorption Cycles for Multicyclic Atmospheric Water Harvesting in Arid Environments

open access: yesAdvanced Functional Materials, EarlyView.
A polyelectrolyte complex‐based sorbent is produced by scalable, environmentally benign aqueous phase inversion. Its porous, LiCl‐ and GO‐integrated architecture enables hourly adsorption−desorption cycles at low relative humidity (RH < 30%). A large‐scale prototype achieves multicyclic, solar‐driven atmospheric water harvesting of 1.37 L kg−1 day−1 ...

Integrated Visible Light and Oxidant Protection Through Multifunctional Sunscreens

open access: yesAdvanced Healthcare Materials, EarlyView.
High‐energy visible radiation (HEVR), although less energetic than UV light, penetrates deeper into the skin and contributes to photoaging, pigmentation disorders, and oxidative stress. The development of new HEVR‐targeted filters, therefore, represents not only a scientific challenge but also a pressing public health and cosmetic industry need.
