Carbon Fiber Reinforced Polymer has gained widely usages cause of high strength-to-weight ratio and stiffness. One kind of Material-Property database of Carbon Fiber Reinforced Polymer based on J2EE technology was constructed based on SQL server to find the relationship between one kind of property data in the same table for one material, otherwise, the development tendency of this material with small property values would be obtained. Simultaneously, the overall structure, functional modules and database design of the system were introduced. The foundation of Material-Property Database plays an important role in data management, data analysis and data development tendency, so as to provide solid technology supports for materials and products design.

We herein described the design, synthesis and application of two recyclable benzyl-type fluorous tags with double fluorous chains. The benzyl-type fluorous tags were prepared in 3 steps from a commercially available fluorous alcohol. The glycosylation of the benzyl-type tags with imidate donors proceeded smoothly to provide the corresponding fluorous-tagged carbohydrates in good to excellent yields, which were readily purified by fluorous solid-phase extraction (FSPE). Efficient removal of the tags from tag-tethered carbohydrates were conducted under the common catalytic hydrogenation condition and the initial benzyl-type fluorous tags could be regenerated via a 2-step simple procedure in 69%–93% yields. The utility of the new benzyl-fluorous tag was demonstrated via the FSPE-assisted synthesis of oligosaccharides Gb3.

Carbon fiber reinforced epoxy composites is playing a role in reducing structural weight and costs, saving resources and optimizing processes. However, the low properties of epoxy matrix and the weak interfacial bonding between carbon fiber and epoxy lead to the poor interlaminar performancec for carbon fiber or fabric reinforced epoxy composites. The application of nanomaterials is an effective way to improve or enhance the interlaminar properties of composite materials. Therefore, this paper summarized the research on the methods of nanomaterialsto reinforce resin matrix, and nanomaterials-carbon fibers multi-scale reinforcement to enhance the interlaminar performace, and nanomaterials to distribute the surface of prepreg uniformly, and nanomaterials to promote interfacial binding energy between carbon fiber and epoxy and nanomaterials macrostructure to improve the interlaminar properties of composites.

Due to the growing needs of thermal management in modern electronics, epoxy-based composites are increasingly demanded in heat dissipating materials. A simple preparation of composites with high thermalconductivity was developed through the graphenenanosheetshomogeneously dispersed in theepoxy matrix. A high thermal conductivityof 0.4843W/mK ( increased by184% over that of pure epoxy) could be obtained for the compositeswith a filler content of 5wt.%. It was proved that high aspect ratio of GNPs are critical issues of theconstitution of a special interface region between the GNPs and epoxy matrix of the composites.The more than mere additive effect on the through-thickness thermal conductivity suggests synergistic physical interactions between graphenenano sheets leading to further enhancement in the through-thickness thermal conductivity. Thus, the graphene-reinforced composites are promising for usageas an efficient heat spreader for heat dissipation applications.

ZnO thin films were prepared on quartz glass substrates by different sol-gel methods using a spin-coating technique. The structural and optical properties of ZnO thin films were studied by X-ray diffraction (XRD) and transmission spectra analysis. The results show that different factors such as Zn2+ concentration, solvent, sol stabilizer, pre-heat treatment temperature, and annealing temperature have a great impact on the structural and optical properties of ZnO thin films.

An efficient method to rapidly synthesize 3-deoxy-d-manno-2-octulosonic acid (Kdo) and its derivatives in large scale has been developed. Starting from d-mannose, the di-O-isopropylidene derivative of Kdo ethyl ester was prepared in three steps on a scale of more than 40 g in one batch in an overall yield of 75–80% without any intermediate purification. Kdo, Kdo glycal, and 2-acetylated Kdo ester were synthesized quickly in high yield from a di-O-isopropylidene derivative of Kdo ethyl ester. 2-Deoxy-β-Kdo ester was obtained with high stereoselectivity via the epimerization of the α-isomer using t-BuOH as a proton source.
