Towards New Degradable Lignin Types
Lignin is the major limiting factor in the conversion of lignocellulosic biomass into liquid biofuels. Over the past decade, researchers have made a number of exciting observations that have significantly extended our possibilities of engineering plant cell walls. One of these findings is that plants can tolerate large variations in the composition of the normal lignin units in the cell wall. S...
متن کاملPropensity of lignin to associate: light scattering photometry study with native lignins.
Many studies of lignins in solution invoke association and aggregation phenomena to explain their solution behavior (e.g., reprecipitation onto pulp fibers, condensation, etc.). Following their colloidal (apparent) molecular weights in solution as a function of time allows us to explore observable dissociation phenomena. These measurements were carried out using multiple angle laser light scatt...
متن کاملDe-etherification of lignin model compounds and lignins
Introduction Lignin is the second most abundant polymer on earth and is found in almost all biomass resources. This inexpensive feedstock is an ideal carbon source that can be used to makes fuels and chemicals. However, there are substantial challenges to convert it into a liquid fuel [1]. Lignin is an amorphous polymer consisting of randomly branched phenylpropenyl (C9) groups. The linkages be...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولLignin‐Retaining Transparent Wood
Optically transparent wood, combining optical and mechanical performance, is an emerging new material for light-transmitting structures in buildings with the aim of reducing energy consumption. One of the main obstacles for transparent wood fabrication is delignification, where around 30 wt % of wood tissue is removed to reduce light absorption and refractive index mismatch. This step is time c...
