Lightweight, Strong, Hydrostable, Bendable, Rolled‐Up, and Biodegradable Straws Enabled by Nano‐ and Microarchitecture Tuning of the Wood Cell Wall and Molecular Welding Strategy

open access: yesAdvanced Sustainable Systems, EarlyView.
An all‐natural straw is fabricated through nano‐ and microarchitectural tuning of the wood cell wall using a molecular welding strategy. These all‐natural straws offer multiple advantages, including superior mechanical performance, excellent water and beverage stability, biocompatibility, full biodegradability, and recyclability.

The Global Warming Potential of Geoengineering via Radiative Cooling

open access: yesAdvanced Sustainable Systems, EarlyView.
The cooling power of engineered radiative cooling materials is determined and compared to conventional construction and roofing materials and Earth's natural surfaces. Results show if 1% of Earth's surface are to be covered with state‐of‐the‐art radiative cooling materials the terrestrial radiative forcing would decrease by 1.61 W·m−2 (from 0.6 to −1 ...
