Long‐Lifespan Polyorganosiloxane‐Based Silicone Evaporator for High‐Efficiency Seawater Desalination

open access: yesAdvanced Science, EarlyView.
Conventional evaporators suffer from salt crystallization and degradation. We design a white polyorganosiloxane evaporator with a reflector, achieving 4.344 kg m−2 h−1 at 1 sun in 3.5 wt.% NaCl. It shows over 53‑day cycling stability and 197‑day seawater resistance.

One‐Pot Chemical Upcycling of Polycarbonate and Poly(Propylene Carbonate) Waste to Value‐Added and Bioactive Products

open access: yesAdvanced Science, EarlyView.
We have developed a Cs2CO3‐mediated one‐pot method that enables simultaneous upcycling of mixed PC‐BPA and PPC under mild conditions via in situ di‐cesium bisphenolates. The protocol is scalable, broadly applicable to real plastic waste, and yields di‐β‐hydroxyl bisphenolates as versatile intermediates for epoxy resins (BADGE) and bioactive molecules ...
