Native celluloses on the basis of two crystalline phase (Iα/Iβ) system

Wada, Masahisa, Sugiyama, Junji, Okano, Takeshi·1993·Journal of Applied Polymer Science

Abstract

A survey by X‐ray diffractometry was carried out to confirm the two crystalline phase Iα/Iβ(triclinic/monoclinic) system of native celluloses. We have investigated cellulose samples from 12 different origins and measured the d‐spacings with reasonable precision. The samples were then subjected to the hydrothermal annealing that brings the cellulose crystals to the monoclinic type; d‐spacings were reevaluated afterward. From the statistical analysis using observed d‐spacings, all the cellulose samples were categorized into the two groups that coincide with the two crystalline phase systems: one is the algal‐bacterial type rich in triclinic phase and the other is the cotton‐ramie type of the monoclinic phase. © 1993 John Wiley & Sons, Inc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
