Electron micrographs, cellulose crystals

Figure 2. Electron micrographs of crystals of cellulose II prepared at 50 C, after shadowing with W/Ta. 2h Sample from microcrystalline cellulose (DP 34) solution. Sample from cotton cellulose (DP 2000) solution. 2C X-ray dic gram, identical for either scunples.

Figure 4. Electron micrographs of crystals of cellulose prepared at 90 C after shadowing with W/Ta. 4A from Avicel (DP 120) cellulose solution the structure consists of rod-like elements together with granular aggregates (arrows). Insert corresponding X-ray diagram. from microcrystalline cellulose (DP 34)solution. Insert corresponding electron diffraction diagram.
