Homogeneous suspensions of individualized microfibrils from TEMPO-catalyzed oxidation of native cellulose.
TL;DR: Never-dried native celluloses (bleached sulfite wood pulp, cotton, tunicin, and bacterial cellulose) were disintegrated into individual microfibrils after oxidation mediated by the 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) radical followed by a homogenizing mechanical treatment.

Native cellulose: a composite of two distinct crystalline forms.
TL;DR: Multiplicities in the resonances of chemically equivalent carbons, which appear in the solid-state carbon-13 nuclear magnetic resonance spectra of native celluloses, have been examined at high resolution and are consistent with the existence of two distinct crystalline forms.
