Study of the degradation behavior of heat-treated jack pine (Pinus banksiana) under artificial sunlight irradiation (2012, background): “[17] Sivonen H, Maunu SL, Sundholm F, Jämsä S, Viitaniemi P.”
Extractive composition and summative chemical analysis of thermally treated eucalypt wood (2008, background): “Their deacetylation leads to acetic acid which is itself a depolymerization catalyst (Tjeerdsma et al. 1998; Sivonen et al. 2002; Nuopponen et al. 2004), while dehydratation induces formation of furfural and hydroxymethylfurfural (Tjeerdsma et al.”
Effect of Heat Treatment on Color Changes, Dimensional Stability, and Mechanical Properties of Wood (2012, background): “Cellulose is less affected by heat treatment in comparison to hemicelluloses because of its semi-crystalline nature.[1,23] Heat treatment generally results in increased proportion of lignin, which may be attributed to relative decrease in carbohydrate proportion and also to hemicellulose dehydration”
Wood modification by heat treatment: a review. (2009, background): “Sivonen et al. (2002) obtained a clear increase of cellulose crystallinity, confirmed by the increase of the peak at 89 ppm (crystalline cellulose) in the NMR spectra in relation to the peak at 84 ppm (amorphous cellulose) in heat-treated Pinus sylvestris at temperatures between 180-230ºC for 4…”
Heat-induced colour changes of pine (Pinus pinaster) and eucalypt (Eucalyptus globulus) wood (2008, background): “The thermal degradation starts by deacetylation of hemicelluloses and the released acetic acid acts as a depolymerization catalysist which further increases polysaccharide decomposition (Tjeerdsma et al. 1998; Sivonen et al. 2002; Nuopponen et al. 2004).”
Control of wood thermal treatment and its effects on decay resistance: a review (2016, unknown): “1998; Militz 2002), Germany (Rapp 2001) and Finland (Kotilainen et al. 2000, Sivonen et al. 2002, Hietala et al .”
Strength properties of thermally modified softwoods and its relation to polymeric structural wood constituents (2007, methodology): “This can result in new lignin based polymers [16] and/or in an increased cross-linking of the existing lignin network [4, 13, 43 , 48].”
Effect of thermal treatment on the chemical composition and mechanical properties of birch and aspen (2008, background): “The increase in crystallization of cellulose due to the degradation of the amorphous hemicelluloses content (Bhuiyan et al. 2000; Dwianto et al. 1996; Kubojima et al. 2001; Sinoven et al. 2002 ) can also slightly increase the hardness under 200 °C.”
Influence of steam heating on the properties of pine (Pinus pinaster) and eucalypt (Eucalyptus globulus) wood (2007, background): “…treatment of wood 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…”
Thermal Modifications in Softwood Studied by FT‐IR and UV Resonance Raman Spectroscopies (2005, background): “13 14 15 Acetyl groups of hemicelluloses are cleaved at relatively low temperatures, liberating acetic acid, which catalyses depolymerization of polysaccharides.”
Determination of formic-acid and acetic acid concentrations formed during hydrothermal treatment of birch wood and its relation to colour, strength and hardness (2006, background): “Along with the improvement in durability, some unwanted effects arise, such as reduction of wood strength (Noack 1969; Rusche 1973; Kubojima et al. 2000) and reduction of hardness ( Sandermann and Augustin 1963 ).”
FTIR-ATR spectroscopic analyses of changes in wood properties during particle- and fibreboard production of hard- and softwood trees (2008, background): “Nevertheless, changes in the extent of polymerisation can occur at lower temperatures and were already found at 180 °C (Sivonen et al. 2002; Garrote et al. 2001).”
