BEIJING July 08. 2024 (Saba) -A team of Chinese researchers has crafted an innovative biomass-derived material using DNA, the genetic blueprint of life, to reduce ambient temperatures by 16 degrees Celsius on sunny days, even under intense solar radiation.
The researchers combined DNA and gelatin into an ordered layered aerogel structure that converts absorbed ultraviolet light into visible light to surpass 100 percent solar reflectance, yielding exceptional radiative cooling, Xinhua said on Monday.
The adoption of biopolymer-based radiative cooling material helps mitigate environmental pollution, according to a study published on Friday in the journal 'Science'.
This aerogel material is poised to revolutionize the energy efficiency of urban architecture as an outer protective layer, said the paper's corresponding author Zhao Haibo from Sichuan University.
The novel aerogel holds promise for significantly reducing carbon emissions and energy consumption and paves the way for innovative and sustainable radiative cooling materials in the future, Zhao added.
