Mechanical engineers lend fresh insight into battery-based desalination technology

A chemical analog to Prussian blue, the intense blue pigment used in Hokusai’s woodblock print “The Great Wave off Kanagawa,” is being utilized in an updated saltwater desalination technique. Mechanical engineers at U. of I. are using it in a new electrode equipped with flow channels to make the desalination process more effective and efficient.

To achieve more effective saltwater desalination in a new study, mechanical engineers have focused on fluid movement rather than new materials. By adding microchannels to the inside of battery-like electrodes made of Prussian blue—an intense …
