TL;DR: In this paper, the changes in cotton fibers after ball milling for 15, 45 and 120 min were analyzed with the Rietveld method; DNP (dynamic nuclear polarization) natural abundance 2D NMR studies in the next paper assisted with the interpretation of the 1D analyses in the present work.

Isolation and characterization of cellulose nanocrystals from jackfruit peel.
C. Trilokesh,Kiran Babu Uppuluri +1 more
TL;DR: Of the three different methods tested, sodium chlorite treatment produced the highest yield of cellulose, 20.08 ± 0.05% w/w (dry weight) and Sulphuric acid hydrolysis was employed to produce SCNCs and examined by TEM for the morphology and by HPLC for the presence of glucose.
Increment in evolution of cellulose crystallinity analysis
TL;DR: French et al. as mentioned in this paper used the Rietveld method for cellulose crystallinity analysis, which includes the smaller peaks that are lost in what appears to be the background or amorphous scattering.

A profile refinement method for nuclear and magnetic structures
TL;DR: In this paper, a structure refinement method was described which does not use integrated neutron powder intensities, single or overlapping, but employs directly the profile intensities obtained from step-scanning measurements of the powder diagram.

An Empirical Method for Estimating the Degree of Crystallinity of Native Cellulose Using the X-Ray Diffractometer
TL;DR: In this paper, an empirical method for determining the crystallinity of native cellulose was studied with an x-ray diffractometer using the focusing and transmission techniques, and the influence of fluctuations in the primary radiation and in counting and recording processes have been determined.

Cellulose nanomaterials review: structure, properties and nanocomposites
Robert J. Moon,Robert J. Moon,Ashlie Martini,John A. Nairn,John Simonsen,Jeffrey P. Youngblood +5 more
TL;DR: This critical review provides a processing-structure-property perspective on recent advances in cellulose nanoparticles and composites produced from them, and summarizes cellulOSE nanoparticles in terms of particle morphology, crystal structure, and properties.
Cellulose crystallinity index: measurement techniques and their impact on interpreting cellulase performance
TL;DR: Four different techniques incorporating X-ray diffraction and solid-state 13C nuclear magnetic resonance (NMR) were compared using eight different cellulose preparations and it was found that the simplest method, which is also the most widely used, and which involves measurement of just two heights in the X- Ray diffractogram, produced significantly higher crystallinity values than did the other methods.
