Sugarcane lignocellulosic matter is represented by bagasse, with its fiber and pith fractions, and trash. This matter is chemically composed by cellulose (41-47%), hemicelluloses (25-26%) and lignin (14-22%). The arrangement of these chemical components in space, in nanometric scale, is here called nanomorphology. The nanomorphological properties addressed in this project are related to two kinds of nanometric structures present in the materials: cellulose fibrils, which are predominantly crystalline, and pores filled with water. This project proposes the characterization of these structures by several techniques. In addition, it aims at understanding the evolution of these structures as conventional processes (related to the enzymatic route of lignocellulosic material conversion to ethanol) are applied. The analytical techniques proposed to characterize the materials nanomorphology are: x-ray diffraction, small-angle x-ray scattering, thermoporometry, water sorption and desorption analysis, solute exclusion, and gas adsorption. This is a promising research area mainly because lignocellulosic matter is an abundant and renewable source of energy and materials. However, in Brazil there is scarcity of researchers working with the nanomorphology of lignocellulosic matter, particularly regarding physical techniques of characterization. (AU)
