Indium oxide nanocrystals with mesoporous structure were successfully synthesized by using triblock copolymer as a template, and characterized by thermogravimetry-differential scanning calorimeter (TG-DSC), X-ray powder diffraction (XRD), high resolution transmission electron microscopy (HRTEM) and N₂ adsorption. A high EO/PO ratio is thought to be the key point to prepare mesoporous In₂O₃. The results show that the average pore diameter of the products is 6 nm, the BET surface area is 54.78 m²/g, and the adsorbing pore volume is 0.345 cm³/g. After comparing with normal indium oxide nanoparticles by BET test, mesoporous indium oxide demonstrates a large difference in adsorbing pore volume and average pore diameters from normal ones.

知识产权领域中的贸易保护主义及应对策略     

董晓雯 《山西师大学报(社会科学版)》2009,36(Z1)

随着全球经济一体化的不断深入,各国为保护本国的贸易利益而对他国设置了一系列名目繁多的贸易壁垒,其中,知识产权壁垒的作用在最近几年中表现的越发突出.认清知识产权国际保护的本质对指导我国如何开展国际贸易无疑具有重要意义.本文以TRIPS为核心的知识产权国际保护体系的建立和发展为视角,力图阐明知识产权的保护与贸易保护主义的关系,并进一步分析说明这种关系所带来的负面效应以及我国应采取的应对策略.  相似文献
