  1. * Reference [7].
  2. Reference [11].
  3. According to manufacture's data.
  4. § Fluka and Sigma are subsidiaries of Sigma-Aldrich.
  5. In the case of Sigmacell 101, no clearly resolved X-ray diffraction profiles were detected. Instead, a smooth peak was detected which is typical for amorphous cellulose according to Hall et al. [107]. Pala et al. [37] found similar results for Sigmacell 101.
  6. CrI, the crystallinity index of cellulose; DP w , the weight-average degree of polymerization;
  7. d P , the geometric mean particle size; CMC, carboxymethyl cellulose.
