The magnetic fields can be measured through the Zeeman effect of radiative emissions of atoms and molecules.

Utilising plastic waste, the team engineered thin-film aerogels that function as thermal insulators and radiative coolers.

The new aerogels developed by the NUS team present a passive cooling alternative, leveraging the natural process of radiative cooling to dissipate heat into space without consuming energy.

In addition to Xu's MOF-based electrochromic film, several other research groups have reported electrochromic coating designs, including a UV-blocking but visually transparent radiative cooling film, a colorful plant-based film that gets cooler when exposed to sunlight, and a temperature-responsive film that turns darker in cold weather and lighter when it's hot.

"A key feature is the ability to efficiently radiate heat through the Earth's atmosphere's long-wave infrared transmission window, releasing heat into the cold expanse of the universe. This allows for passive radiative cooling without electricity consumption," explains Bryce S. Richards, Professor at IMT and LTI.
