Inspired by Schools of Fish, This Magnetic Material Swarms to Eat Carbon Dioxide

Universe Today - Mon, 12/08/2025 - 6:39am

Removing, or “scrubbing”, carbon dioxide from the air of confined spaces is a critical component of any life support system on a spacecraft or submarine. However, modern day ones are energy intensive, requiring temperatures of up to 200℃ to operate. So a research lab led by Dr. Hui He at Guangxi University in China has developed what they call “micro/nano reconfigurable robots” (MNRM) to scrub CO2 from the air much more efficiently. Their work is described in a new paper in Nano-Micro Letters.
