Figure 1
(a) Typical two-dimensional cellulose diffraction pattern (background subtracted) of a 20 µm-thick single cellulose fibre, measured with a 2 µm × 2 µm X-ray beam in 2 s (beamline ID13, ESRF). (b) Typical two-dimensional cellulose diffraction pattern (raw data without background subtraction) of a 200 µm-thick tangential section of pine wood, measured with a 250 µm × 250 µm X-ray beam in 3 s (beamline A2, HASYLAB). The circle in the centre of the image is scattering at the Kapton beam exit window; the shadow is from the beam stop holder. The strongest reflections on the equator of the fibre diffraction diagrams (left and right of the centre) correspond to the (200) Bragg planes of native cellulose I. |
