With the rapid development of the space industry, enhancing the stealth and survivability of spacecraft has become a critical challenge. Professor Qiang Li’s team at Zhejiang University has developed an innovative multilayer thin-film camouflage device, enabling invisibility across H, K, MWIR, and LWIR bands while efficiently radiating heat to address thermal control issues in space. This technology achieves precise management of solar and thermal radiation, offering significant support for future space exploration.

MIT engineers developed a fuel cell that offers more than three times as much energy per pound compared to lithium-ion batteries. Powered by a reaction between sodium metal and air, the device could be lightweight enough to enable the electrification of airplanes, trucks, or ships.
