In the bustling streets of Shanghai, China, scientists at Jiao Tong University are propelling the world into a new era of climate control with their pioneering invention: the Janus thermal cloak. Harnessing the power of silica, aluminium, and hexagonal boron nitride, this two-layered ‘cloak’ serves a dual purpose, modulating temperatures by cooling during the summer and warming in the winter, a trait akin to its namesake, Janus – the dual-faced Roman deity. The Inner Workings of the Thermal Titan Mirroring the Earth’s own cooling mechanism, the Janus cloak uses radiative cooling. The cloak’s outer skin, adorned with boron nitride-coated silica … Continue reading Enter the Next Level of Thermal Management: Shanghai’s Miraculous Janus Cloak
