On July 5th, Academician Shen Changyu and Dr. Liu Xianhu of National Engineering Research Center of Rubber-Plastic Mold, Zhengzhou University published the perspective"DNA and Gelatin-a Cool Aerogel Mix" in Science (Science, 2024,385,30). Combined with the new progress in the field of radiation refrigeration in recent years, this article reviewed the Science paper “ A Photoluminescent Hydrogen-bonded Biomass Aerogel for Sustainable Rediaitve Cooling” by Ma (Science, 2024,385,68),and expect biodegradable polymer radiation cooling materials. Zhengzhou University is the only communication unit of the paper.
