UW-Madison researchers James Dumesic and Jeremy Luterbacher use a plant-derived chemical, called gamma valerolactone or GVL, to produce a concentrated stream of sugars. Luterbacher (right) holds a vial containing light colored concentrated sugar solution, which spontaneously separates from the dark GVL when high salt or high sugar concentrations are present or when liquid carbon dioxide is added to the mixture.
