“Warm in Winter and Cool in Summer”: Scalable Biochameleon Inspired Temperature-Adaptive Coating with Easy Preparation and Construction

Nano Letters, Journal Year: 2023, Volume and Issue: 23(19), P. 9034 - 9041

Published: Sept. 20, 2023

The highly reflective solar radiation of passive daytime radiative cooling (PDRC) increases heating energy consumption in the cold winter. Inspired by temperature-adaptive skin color chameleon, we efficiently combine absorption and PDRC technology to achieve "warm winter cool summer". coating (TARCC) with variability is designed fabricated, achieving 41% visible light regulation capability. Comprehensive seasonal outdoor tests confirm reliability TARCC: summer, TARCC exhibits high reflectance (∼93%) atmospheric transmission window emittance (∼94%), resulting a 6.5 K subambient temperature. In winter, TARCC's dark strongly absorbs radiation, 4.3 temperature rise. Compared coatings, can save up 20% annual midlatitude regions increase suitable human hours 55%. With its low cost, easy preparation, simple construction, shows promise for sustainable comfortable indoor environments.

Seawater Interfacial Evaporation in Composite Gel Enables Photovoltaic Cooling, Simultaneous Seawater Desalination, and Enhanced Uranium Extraction

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 31, 2025

Abstract Overheating of photovoltaic (PV) panels poses a huge challenge to their practical operation. Herein, novel design is proposed that uses seawater interfacial evaporation integrate PV cooling, desalination, and uranium extraction. The sodium alginate (SA) gel with adsorbent filled utilized verify the efficacy this design. As light intensity increases from 0.5 1.5 suns, rate doped SA rises 0.98 2.62 kg m −2 h −1 , output gain panel 4.9 13.1% owing cooling effect gel. Additionally, high adsorption ratio exceeding 90% in 50 mg L solution or obtained under 1 sun (in‐lab). outdoor experiments imply composite can lower surface temperature by up 12 °C, maximum 8%. Meanwhile, capacity 6 g over 10 days also obtained. In summary, our work shows meaningful for multiple resources energy through offshore platforms.
