Leonard MacGillivray leads cadmium MOF prototypes
Led by Leonard MacGillivray at the University of Iowa, the team found that UV light kicks off a reaction that turns the crystals into tiny sponges, trapping water inside them.
Right now, the prototypes use cadmium, but researchers are working on switching to safer metals like zinc, so it's safe for drinking.
The big goal? A simple device that runs on sunlight and brings safe water to dry, remote, off-grid places, no electricity or energy-intensive infrastructure needed.
