"Characterization of CO2 Precipitated Kraft Lignin to Promote its Utilization," an article by the Institute of Paper Science and Technology at Georgia Tech (Atlanta, Ga., USA) team of Arthur J. Ragauskas, professor of chemistry and biochemistry, and Ph.D. students Máté Nagy, Matyas Kosa, and Hans Theliander, was among the top ten accessed on the web from the online version of Green Chemistry in January.

The study reported in the article examines the fundamental chemical structure of lignin recovered from kraft pulping streams by an acid precipitation/washing methodology. Functional group analysis and molecular weight profiles were determined by NMR and SEC with promising results for future conversions; such as low hydroxyl (oxygen) contents and low molecular weights.
