Abstract:
Small-angle X-ray scattering (SAXS) experiments with in situ dehydration have been performed on small bundles of flax fibers. Analysis indicated that the structure of the cellulose microfibrils is consistent with a cross section of approximately 10 x 50 A2. The microfibril misalignment was Gaussian with a full width at half-maximum of 11-15 degrees, dependent on hydration level. A meridional peak at q = 0.095 A-1 was observed, possibly for the first time in cellulose I fibers, and this has been attributed to a crystalline/noncrystalline repeat repeat distance of 60-70 A. It has also been noted that there is considerable change in structure as flax fibers dry from the wet state.

Diffraction
Diffraction is the change in the direction of travel experienced by an electromagnetic wave when it encounters a physical barrier whose dimensions are comparable to those of the wavelength of the light. X-rays are electromagnetic radiation with wavelengths about as long as the distance between neighboring...

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
