The mechanical nanofibrillation of holocellulose nanofibers (HCNFs) and the recrystallization of mannan.

Caption

Spent coffee grounds are purified to yield holocellulose, which is then reduced to HCNFs using mechanical nanofibrillation. The HCNFs are 2-3 nm and 0.7-1 mm in length. An AFM (Atomic Force Microscopy) image of the HCNF shows recrystallization of mannan.
