Composition and Basic Structure Analysis of SMS Polysaccharides;

Result: The values of expansion degree were decreased and the structures of polysaccharides were changed for the processed products compared with their crude seeds.

Improvements of the photo-electric characteristics induced by introduction of a series of advanced materials and structure,such as composite core-shell structure,doped TiO_2 electrodes,optimized materials and hierarchical structures are discussed in detail.

The chemical composition,hierarchical structure,structure-activity relationship,detection method and physiological function of medicinal fungi polysaccharides were introduced and the future research direction was proposed.

The results indicated that ZSM-5 zeolite with uniform size of 300-400 nm was synthesized, and it was spherical-like aggregates and has hierarchical structure constructed by many ZSM-5 nanotubes of 20-40 nm.

Aldononitrile acetates and alkaline nitrobenzene oxidations were used to analyze the change of structural polysaccharides and composition of lignin in 80 % ethanol-extracted rice straw treated with sodium hydroxide,ammonium bicarbonate,or urea.

Mesoporous materials with the primary structure units of zeolite in the pore wall have been synthesized by a two-step crystallization process at 140 ℃ and characterized by XRD, N 2 physical adsorption/desorption, TEM, IR and NH 3-TPD methods.
