We've been hearing more and more about eco-friendly biodegradable plastics, made from cellulose nanofibers. Although those fibers are typically harvested from wood waste, new research shows that they ...
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 ...
