Humans have relied on biomass for survival and development since the Stone Age. All aspects of human needs for materials are covered by tools, fuel, and buildings. Nowadays, metals and petroleum-based materials are widely used in highly developed industries. Unfortunately, environmental contamination and the loss of natural resources have led to the reemergence of biomass resources as efficient and sustainable energy sources. Notably, simple and direct applications can no longer meet the demand for functionalization, high performance of materials and construction materials. Therefore, it is imperative to modify biomass and combine its utilisation to produce functionalization and high performance materials. For example, construction materials with superior mechanical properties and water resistance can be produced by reinforcing fibres to facilitate crosslinking. Water-oil separation or adsorption effects of hydrogels and aerogels are determined by the porosity and lightness of biomass, biocomposite conductor is prepared by chimaeric conductive material. Here, we review the approaches that have been taken to devise an environmentally friendly yet fully recyclable and sustainable functionalised biocomposites from biomass and its potential directions for future research.

引用

Science china Chemistry 2009年第4期52卷 523-528页

作者： ZENG Xi,WU Chong,DONG Lei,MU Lan,XUE SaiFeng & TAO Zhu college of Chemistry and Chemical Engineering ,guizhou University,guiyang 550003,china Key Laboratory of Macrocyclic and Supramolecular Chemistry of guizhou province,guizhou University,guiyang 550025,china college of Chemistry and Chemical Engineering Guizhou University Guiyang 550003 China Key Laboratory of Macrocyclic and Supramolecular Chemistry of guizhou province Guizhou University Guiyang 550025 China

A new tripodal rhodamine B derivative 2 was designed and synthesized by tripodal trialdehyde and rhodamine B hydrazide for the first time. This derivative could be used as a fluorescent chemosensor for the selective and sensitive determination of copper(II) in Tris-HCl buffer and ethanol aqueous mixed media. Under the optimum conditions described herein,fluorescence enhancement at 557/577 nm was linearly related to the concentration of copper(II) in the range of 0.10 to 10.00×10-5 mol·L-1,with a corre-lation coefficient of r2=0.9964 (n=15) and a detection limit of 1.129×10-7 mol·L-1 (the relative standard deviation for five repeated measurements at 4.00×10-5 mol·L-1 Cu(II) was 2.2%). The absorbance meas-urements at 557 nm were linearly related to the concentration of Cu(II) in the range of 0.50 to 25.00×10-5 mol·L-1,with a correlation coefficient of r2=0.9948 (n=13) and a detection limit of 3.338×10-7mol·L-1.

Speciation of the genus Arthricocephalus Bergeron, 1899 (Trilobita) from the late Early Cambrian and its stratigraphic significance

引用

progress in Natural Science:Materials International 2006年第6期16卷 614-623页

作者： YUAN Jinliang, ZHAO Yuanlong and YANG Xinglian (Nanjing Institute of Geology and palaeontology, Chinese Academy of Sciences, Nanjing 210008, china college of resource and Environment of guizhou University, guiyang 550003, china) [a] Nanjing Institute of Geology and palaeontology Chinese Academy of Sciences Nanjing China [b] college of resource and Environment of guizhou University Guiyang China

The genus Arthricocephalus Bergeron, 1899 is revised, and Halipanktos Balker & peel, 1997 is suggested here as a senior synonym. The subgenus Arthricocephalus (Arthricocephalites) Chien & Lin in Lu et al. , 1974 is considered as a separate genus. Of the 20 previously assigned species of Arthricocephaius (Arthricocephalus) Bergeron, 1899, Arthricocephalus (Arthricocephalites) Chien & Lin in Lu et al. , 1974, Arthricocephalus (Euarthricocephalus) Ju, 1983 are lumped into eight species. The speciation trend of Arthricocephalus and Arthricocephalites is demonstrated based on their stratigraphic occurrences. It not only enhances the resolution of the biostatigraphic zonation in the uppermost Lower Cambrian, but also represents a potential candidate to define the Duyunian stage. The base of the stage is suggested at the first appearance datum (FAD) of Arthricocephalus chauveaui Bergeron, 1899 within the evolutionary lineage from Ar. jiangkouensis Yin in Yin & Li, 1978 to Ar. chauveaui in a global scale.

BACKGrOUND: Hepatic fibrosis is the common patholo gical change in various chronic liver diseases,and its major cause is the imbalance between the production and degra dation of the extracellular matrix, which is mainly com posed of collagens. Dan-Shao-Hua-Xian ( DSHX) cap sule, a traditional Chinese herbal compound, has shown marked preventive effects on hepatic fibrosis in rats in our previous studies. The present study was designed to further investigate its therapeutic actions on hepatic fibrosis in rats and its possible mechanisms. METHODS: Eighty male Wistar rats were randomly divid- ed into normal control group, hepatic fibrosis group, non DSHX-treated group, low-dose-treated group, and high dose-treated group. The rat models of hepatic fibrosis were established by subcutaneous injecton of CC14 , drinking al- cohol , giving diet of hyperliprosis and hypoprotein for 8 weeks. The two DSHX-treated groups were treated respec- tively with low dose (0.5 g/kg) and high dose (1.0 g/kg) of DSHX capsule p. o. everyday for 8 weeks. At the end of the experiment, liver indexes were calculated in each group in addition to the levels of the serum hyaluronic acid and alanine aminotransferase. Their degree of hepatic fibrosis and urinary excretion of hydroxyproline and expression of collagen , were detected. rESULTS: Comparison of the indexes of the hepatic fibro- sis group and non-DSHX-treated group revealed that the liver indexes, levels of serum hyaluronic acid and alanine aminotransferase, and stage of hepatic fibrosis were all sig- nificantly reduced in the two DSHX treated groups. The urinary excretion of hydroxyproline was increased and the expression of collagen I and HI in liver tissue was lessened. These alterations were more obviously observed in the high-dose-treated group. CONCLUSION: DSHX capsule has certain therapeutic effect on hepatic fibrosis in rats.
