Laurence N. Warr Article Correction Metrics Get access Share Cite Rights & Permissions Abstract WebX-Ray diffraction analysis. Cellulose crystallinity was determined by X-ray diffraction (JDX-3530, JEOL, Tokyo, Japan). Samples of each size fraction were analyzed. All samples were scanned from 2 ¼ 7 to 40 with a step size of 0.02 . Determination time was 1s/0.02 . The crystallinity index (CrI) was defined as follows: CrI ¼ðI 002 I amÞ ...

Several techniques, such as infrared spectroscopy, x-ray diffraction, and optical analysis, can be used for determining the amorphous content or the crystallinity.
WebMar 12, 2014 · We report the growth of crystalline Al 2 O 3 thin films deposited by thermal Atomic Layer Deposition (ALD) at 200 °C, which up to now has always resulted in the amorphous phase. The 5 nm thick films were deposited on Ga 2 O 3, ZnO, and Si nanowire substrates 100 nm or less in diameter.
WebCase studies are presented to illustrate the effect of different process parameters on crystallinity for representative materials: aluminium oxide, zirconium oxide, zinc oxide, titanium nitride, zinc zulfide, and ruthenium. Finally, we discuss the general trends in the development of film crystallinity as function of ALD process parameters. dark iphone 6 wallpaperWebCotton cellulose differs from wood cellulose primarily by having a higher degree of polymerization and crystallinity.
