Utilising plastic waste, researchers from the National University of Singapore engineered thin-film aerogels that function as thermal insulators and radiative coolers. In this demonstration, the white aerogel insulates the area underneath from the surrounding heat, while simultaneously cools the area through radiative cooling, as shown by the lower temperature on the upper surface of the aerogel compared to the temperature of the hot water basin.

Researchers from the National University of Singapore developed an innovative aerogel that demonstrates an impressive performance of absorbing electromagnetic energy. In this demonstration, the mobile phone shielded by the grey aerogel recorded a significantly slower WiFi speed, indicating the absorption of electromagnetic waves received by the mobile phone.
