Extractive composition and summative chemical analysis of thermally treated eucalypt wood (2008, background): “The ether linkages of lignins are cleaved and new free phenolic hydroxyl groups and a- and b-carbonyl groups arise, which are responsible for crosslinking via formation of methylene bridges (Tjeerdsma et al. 1998; Nuopponen et al. 2004; Wikberg and Maunu 2004; Tjeerdsma and Militz 2005).”
Impact of hot compressed water pretreatment on the structural changes of woody biomass for bioethanol production (2011, background): “Various pretreatment technologies have been developed, including dilute acid, ammonia, steam explosion, ethanol organosolv, sulfite pretreatment (SPORL), and ammonia fiber explosion (AFEX) (Alizadeh et al. 2005; Gupta and Lee 2009; Pan et al. 2005; Sassner and Zacchi 2008; Wyman et al. 2005).”
Colour in thermally modified wood of beech, Norway spruce and Scots pine. Part 1: Colour evolution and colour changes (2009, background): “This may be linked to the production and subsequent destruction of chromophoric species, probably originated from extractives, and/or due to condensation and re-polymerisation of the lignin substance (Wikberg and Maunu 2004).”
Mechanics of balsa (Ochroma pyramidale) wood (2015, background): “The degree of crystallinity has been determined to be typically on the order of 40-60% for both softwoods and hardwoods (Andersson et al. 2004; Wikberg and Maunu 2004; Penttilä et al. 2013).”
Wood modification by heat treatment: a review. (2009, background): “Other authors point out that the enhanced inaccessibility of hydroxyl groups to water molecules due to the increase of cellulose crystallinity are also significant (Wikberg and Maunu 2004; Bhuiyan and Hirai 2005; Boonstra and Tjeerdsma 2006).”
Influence of steam heating on the properties of pine (Pinus pinaster) and eucalypt (Eucalyptus globulus) wood (2007, background): “…has been active regarding the understanding of the chemical changes in treated wood (Kotilainen et al. 2000; Zaman et al. 2000; Sivonen et al. 2002; Wikberg and Maunu 2004; Nuopponen et al 2004a, b; Bhuiyan and Hirai 2005; Tjeerdsma and Militz 2005; Boonstra and Tjeerdsma 2006;Yamauchi et al.…”
