The extractability of hemicellulose from different lignocellulosics depends on the source of biomass. Differences in hemicellulose extractability are believed to be due to plant-specific hemicellulose arrangement alongside lignin within the cell wall. In this research, six biomasses were used to probe hemicellulose alkaline extractability as a function of the native lignin within the biomasses. Quantitative...
The impact of field-grown transgenic trees on wood characteristics and enzymatic saccharification was evaluated. Genes 4CL and CAld5H were down regulated or overexpressed to modify the lignin content or structure (S/V ratio) on black cottonwood (Populus trichocarpa Nisqually-1). These transgenic trees were grown in the real environment and evaluated after 2 and 3 years. The results exhibited that...
The objective of this research is to provide the first account of a simple preparation of surface fluorinated bulk cellulose nanocrystals and a characterization of their physical and chemical properties. The surface fluorinated, or polyfluorinated cellulose nanocrystals were first generated by reacting bulk cellulose with hydrochloric acid in an aqueous medium to yield cellulose nanocrystals that...
The heat of vaporization (Hvap) of water associated with cellulose fibers versus moisture ratio was determined using modulated differential scanning calorimetry. A steep increase in the Hvap for decreasing moisture ratio was observed at low moisture ratios (0.0–0.3 g/g), indicating a higher energy required to evaporate water interacting with the cellulose. The water molecules with elevated Hvap...
A new method is applied to classify water, termed ‘hard-to-remove (HR) water’, in a cellulosic fiber and water system from an isothermal thermogravimetric analysis (TGA). The hard-to-remove (HR) water content is defined as the moisture ratio (g of water / g of dry sample) of the fiber-water system at the transition between the constant rate zone and the falling rate zone of evaporative change in mass...
