Optimizing Instant Rice Quality of Milled and Brown Rice Through Cultivar‐Selection

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Instant rice products are increasingly favored for convenience; however, achieving consistent quality, particularly rehydration performance and texture, remains a challenge. Rice cultivars differ in physicochemical properties that influence processing behavior and final product quality, yet systematic screening ...

Closing the Loop in Agrivoltaics: A Radiative Cooling Coating for Synergistic Self‐Cleaning and Water Harvesting

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanostructured photonic‐thermal coating enables radiative‐cooling‐induced condensation and water harvesting, establishing a self‐sustaining agrivoltaics microclimate loop that transforms PV panels into active climate regulators. The integration of photovoltaic (PV) panels into agricultural landscapes (i.e., agrivoltaics) offers a promising path for ...
