    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.
