摘要：
Eucalyptus leaves have been used as a common traditional herbal medicine for more than 200 years. In order to further utilize Eucalyptus leaves in biomedicine and put forward new ideas for biomedical manufacturing, the biomedical resources of extractives of Eucalyptus dunnii and Eucalyptus grandis leaves were analyzed by GC/MS. The results showed that: 1) The main constituents of benzene/ethanol extractives in E. dunnii leaves were α-amyrin(9.05%), cyclohexyl-15-crown-5-(6.51%), 1, 4, 7, 10, 13, 16-hexaoxanonadecane, 18-propyl-(6.09%), vitamin E (5.83%), 1, 19-eicosadiene(5.65%), 1, 4-dioxane-2, 6-dimethanol(5.32%), coumarin-6-ol, 3, 4-dihydro -4, 4-dimethyl-7-nitro-(4.42%), 2-furancarboxaldehyde, 5-(hydroxymethyl)- (4.21%), benzene, 1, 2, 3 -trimethoxy-5-methyl(3.45%), etc. 2) The main constituents of benzene/ethanol extractives in E. grandis leaves were (-)-globulol (7.35%), 1, 2, 3-benzenetriol(7.17%), D-allose(6.37%), 2- furancarboxaldehyde, 5-(hydroxymethyl)-(6.33%), N1-(4-hydroxybutyl)-N3-methylguanidine acetate(5.35%), 1, 4, 7, 10, 13, 16-hexaoxanonade-cane, 18-propyl-(3.95%), vitamin E(3.26%), cyclohexyl-15-crown-5-(3.13%), eucalyptol(2.91%), etc. The results of function analyses suggested that the benzene/ethanol extractives of both E. dunnii and E. grandis leaves were abundant in materials of noble natural biomedicines, and also contained constituents which could be developed into top value-added materials of cosmetics and health care. © (2010) Trans Tech Publications.

摘要：
PLA/BF composites,which are extremely flammable, must be carried out fire-retardant processing. However,traditional organic flame retardants release certain amount of pollutant to the environment,and inorganic flame retardants require more addition,which influenced the mechanical properties of composites. Therefore,nano inorganic flame retardants,which have some characteristics of small size,uniform shape and high specific surface area, can bring good flame-retardant effect with relatively few addition. Meanwhile,it can enhance the interaction of composites interface,and disperse more evenly in polylactic acid (PLA)matrix.Furthermore, it has light influence on the physical mechanical properties. In this study, nano structure anhydrous magnesium carbonate is used as flame retardant,Cone Calorimeter and Dynamic Thermal Mechanical Analyzer are adopted for studying the fire-retardant properties and the dynamic thermodynamic parameters of the PLA/BF composites, respectively. Results show that nano structure anhydrous magnesium carbonate flame retardant have good fire-retardant performance for the PLA/BF composites,considering practicality and economy,its ideal addition is 5%.

摘要：
Eucalyptus camaldulensis biomass has been widely used in fiber and pulp. However, this would result in serious water pollution and meanwhile bring a great waste of biological resources. Therefore, the ether/acetone extractives of Eucalyptus camaldulensis biomass were identified by Py-GC/MS. The main 350°C pyrolysis components were 7-Oxabicyclo[3.3.1]non-2-ene, 8-(4-methoxyphenyl)- 2,4,9-trimethyl- (7.1%), Indolo[2,3-b]quinoxaline, 1-fluoro(4.23%), etc. The main 550°C pyrolysis components were 7-Oxabicyclo[3.3.1]non-2-ene, 8-(4-methoxyphenyl)- 2,4,9-trimethyl-(7.1%), Indolo[2,3-b]quinoxaline, 1-fluoro(4.23%), etc. And the main 750°C pyrolysis components were oleic acid(6.77%), 10,18-bisnorabieta-5,7,9(10),11,13 -pentaene(2.33%), 9,12-hexadecadienoic acid, methyl ester(2.12%), etc. So the ether/acetone extractives of Eucalyptus camaldulensis could be used as biomedicine. © (2010) Trans Tech Publications.

摘要：
ZnO nanostructured thin films formation in situ on the surface of bamboo via a low temperature aqueous solution route is studied. The effects of immersion time in seed solution, growth solution concentration, growth time, and pH of seed solution on ZnO morphology are also discussed. Field emission scanning electron microscopy is used to examine the surface morphology of the samples and X-ray powder diffraction is used to detect crystal structure and crystallinity. Results reveal that: prolonging the immersion time, the morphology of the films transforms from grain-net-line-cylinder-to-hexahedron; increasing the growth solution concentration, the compactness of surface films is enhanced as well as there is an enlargement on the size of the line, hexadron, cylinder; and self-assembled ZnO films is a promising material for bamboo protection, and prevents wood material from discoloration, degradation, and ageing when exposed to sunlight.

摘要：
The fibre-reinforced green composites made from bamboo fibre and biodegraded resin(Polylactic Acid) were fabricated by injection molding, effects of alkali treated bamboo fibres on mechanical properties ( tensile strength and impact strength) of fibre-reinforced green composites were studied, and variance of main chemical components of alkali treated bamboo fibres and untreated bamboo fibres was characterized by FT-IR spectroscopy, the tensile fracture surfaces and the interfacial adhesion of composites were examined by scanning electron microscopy(SEM). Results showed that surface of alkali treated bamboo fiber became loose and existed gaps, under pressure action polylactic acid melt infiltrate through fiber surface layer, so "glue nails" were formed on the interface polylactic acid and bamboo fiber, interface mechanical occlusive action was improved, therefore mechanical properties of green composites was increased. ©2010 IEEE.

摘要：
Collapse-type shrinkage is the greatest obstacle to prevent planted eucalypts from being used for solid wood products. In order to make the suitable drying schedules for high effective utilization of eucalypt wood, the total shrinkage and collapse on two species of difficult-to-dry E.urophylla and E.grandis wood under continuous and intermittent drying regimes were measured. The results show that total shrinkage and collapse in both eucalypts exhibited higher values for continuous drying than intermittent drying. With increasing drying temperature, total shrinkage and collapse increase in both drying regimes, while the increasing magnitude of both parameters becomes apparently larger for continuous drying than intermittent drying regime, in particular higher temperature condition. Properly elevating drying temperature to make up for the intermittent-waiting time may be allowed for intermittent drying regime. Drying duration at each intermittent drying period has a greater effect on total shrinkage and collapse of eucalypt wood. When more than a drying duration of 6 hours at an intermittent drying period is used, the differences in shrinkage and collapse between both drying regimes are very slight. Intermittent duration at an intermittent drying period has a comparatively larger effect on total shrinkage and collapse. Accordingly, we may draw a conclusion that intermittent drying regime is very likely to be a potential drying one suitable for collapse-prone lower-density plantation-grown eucalypt wood. © (2010) Trans Tech Publications.

摘要：
阐述了棉秆陶瓷的制备过程,并利用X射线研究了不同温度和原料配比所制备的棉秆陶瓷在炭化过程中的结构变化。结果表明,随着炭化温度的升高和酚醛树脂的增加,XRD谱图中衍射峰、强度以及石墨化程度逐渐增大,而石墨微晶的平均层间距d（002）逐渐减小。

摘要：
Plantations have been planted in large area in South China now. A mass of leaves was naturally abandoned and degradable so that the resources were wasted. Therefore, in order to make full use of the leaves resources, the effect of bioactive substance in leaves on bamboo biomass moulding was studied based on full-factor test. The result is: (1) Tree species of leavies extractives had highly obvious influence on bamboo biomass moulding. Tree species of leavies was key to preparation of mould inhibitor. And treatment time had no influence on bamboo biomass moulding. And treatment time was adjusted based on the anti-mold effect of the leavies extractives on bamboo biomass moulding. (2) The optimal anti-mold effects of bamboo biomass was the leavies extractives of Cinnamomum camphora and Cornus controversa. The next was Cryptomeria japonic, Cupressus funebr, Masson pine, Pterocarya tonkinesis, and Idesia polycarpa. The worse were Metasequoia glyptostroboides. ©2010 IEEE.
