Using Raman Spectroscopy to Analyze Wood, Cellulose-Nanomaterials, and Their Composites
Snapshot: Raman spectroscopy provides information based on molecular vibrations and is well-suited to analyze wood and cellulose-nanomaterials. Using a recently developed method to determine the fraction of cellulose that is in a crystalline region, this research project determined that cellulose crystals do not exist in green wood. The project alsohas been able to follow the formation of crystalline regions with wood processing for biorefinery and cellulose nanomaterials.
