Chemists at the University of Iowa recently developed a millimeter-scale, 3D lattice capable of pulling water directly from the air and storing it. This discovery, published in the Journal of the American Chemical Society, introduces a novel method for addressing global water scarcity, relying entirely on freely available sunlight to trigger the process.The material is a specialized metal-organic framework constructed from metal atoms connected by organic molecules. Initially, the research team’s structural design lacked the internal cavities needed to trap water. However, they discovered that exposing the material to ultraviolet light causes a chemical reaction that fundamentally alters its architecture.
