From: Theoretical study of cellulose II nanocrystals with different exposed facets

The structure and crystal facets of cellulose II nanocrystals. (A) The geometry of six types of cellulose II nanocrystal models. 6A6, 6A12, 6A19, and 10A12 denote 6 × 6 × 6, 6 × 6 × 12, 6 × 6 × 19, and 10 × 10 × 12 the crystal models with the crystal facets \((\overline{{1}} \; {1}\; {2)}\), respectively. 6B12 and 6O12 are 6 × 6 × 12 crystal models with \((\overline{{2}} \; {2}\; {1)}\) and (0 0 1) as crystal facets respectively; (B) Three types of inclined crystal facets. (C) 6 × 6 and 10 × 10 are the chain numbers of the ab base plane projections.
