image: The flow-through reaction setup progressively dissolves biomass, producing fractions that are rich in (from left to right) lignin monomers, hemicellulose and cellulose-derived sugars. This image relates to a paper that appeared in the Jan. 17, 2014, issue of Science, published by AAAS. The paper, by Jeremy Luterbacher at University of Wisconsin -- Madison in Madison, Wis., and colleagues was titled, "Nonenzymatic Sugar Production from Biomass Using Biomass-Derived γ-Valerolactone." view more
