• Heat-induced colour changes of pine (Pinus pinaster) and eucalypt (Eucalyptus globulus) wood (2008, background): “Amorphous cellulose is also degraded resulting in an increase of cellulose crystallinity (Bhuiyan and Hirai 2000, 2001, 2005; Wikberg and Maunu 2004; Boonstra and Tjeerdsma 2006).”
• A review of wood thermal pretreatments to improve wood composite properties (2013, unknown): “Reduction of the degree of polymerization of cellulose results from the regeneration of free radicals, elimination of moisture, formation of carbonyl and carboxyl groups, and formation of carbon dioxide (Bhuiyan et al. 2000, 2001).”
• Colour changes and acid formation in wood during heating (2004, background): “Increased Colour changes and acid formation in wood during heating 15 crystallinity for the cellulose of heat-treated wood compared to untreated wood has been reported for X-ray diffraction measurements (Bhuiyan et al. 2000).”
• Strength properties of thermally modified softwoods and its relation to polymeric structural wood constituents (2007, background): “Heat treatment under moist conditions, such as the hydrothermolysis stage, appears to have a stimulating effect on the crystallization of amorphous cellulose [3].”
• Extractive composition and summative chemical analysis of thermally treated eucalypt wood (2008, background): “The hydrolysates of autoclave treated samples showed a small decrease of glucose in relation to its original content in untreated wood (Table 2), which indicates some thermal induced effect on cellulose, namely on its amorphous regions (Bhuiyan and Hirai 2000, 2001, 2005; Wikberg and Maunu 2004).”
• Influence of drying method on the material properties of nanocellulose I: thermostability and crystallinity (2013, background): “Heat treatment can increase the crystallinity of cellulose (Bhuiyan et al. 2000; Yildiz and Gümüşkaya 2007).”
• Effect of thermal treatment on the chemical composition and mechanical properties of birch and aspen (2008, background): “On the other hand, for aspen, there is degradation of amorphous cellulose content and increase in relative crystallinity with heat maximum treatment temperature ( Bhuiyan et al. 2000; Dwianto et al. 1996; Kubojima et al. 2001; Sinoven et al. 2002) and this might explain the slight increase in MOE.”
• Crystallinity of wood and the size of cellulose crystallites in Norway spruce (Picea abies) (2003, background): “For example, it has been found that crystallinity increases with steaming treatment but decreases with heat treatment.(13,18)”
• Effect of thermal treatment on the physical and mechanical properties of phyllostachys pubescen bamboo (2012, background): “More crystallization is found and it is due to other components in wood which are involved in the increase of crystallinity accompanying wood cellulose during thermal treatment (Bhuiyan et al. 2000).”
