查询词典 ordered pair

We prepared the ordered porous alumina membrane by a two-step anodization method in oxalic or sulfuric acids, which is a self-ordered hexagonal array of cells with an adjustable pore diameter of 20-150nm and a different pore structures (i.e. Y-branched, dendriform, toothed and torous ones). Furthermore, the template-electrodeposition, vapor-catalytic growth, and controlled chemical etching were developed for well-aligned carbon nanotubes and oxide nanopillars with adjustable diameter, Al2O3-AlN one-dimensional heterojunction, Y-junction and dendriform metal nanowires, as well as Y-junction, and torous carbon nanotubes. The resultant one-dimensional junctions were characterized by XRD, SEM, TEM,HRTEM, and STM, and the field emission of the well-aligned carbon nanotubes and the luminescence of ZnO nanopillar array have also been mearsured.

Ordered Sr_2CeO_4 nanowire arrays embedded in anodic alumina membranes were fabricated by a converse transport technique that precipitations were shaped into one dimension structure in the hexagonally ordered nanochannels of the AAM and changed into the Sr_2CeO_4 nanowire by the subsequent treatment.

以多孔阳极氧化铝为模板，采用逆向迁移技术，在模板的纳米孔道内反应形成一维纳米结构前驱体，再经后续处理，制得了Sr2CeO4纳米线。

Synthesis and chracterization of high ordered Ladderlike Polysilsesquioxane Since Brown first reported the synthesis of ladderlike polyphenylsilsesquioxane via "thermal equilibration polymerization"in 1960, it is still a question whether ordered ladderlike polysilsesquioxane can be prepared or not all over the world till now.

第一部分高规整性梯型聚硅氧烷的合成1960 年Brown 首次报道了用&热平衡缩聚法&合成含梯形结构的聚苯基倍半硅氧烷，但该报道受到许多研究者的质疑。至今40 多年来对能否合成真正规整梯形结构的聚倍半硅氧烷一直存在着争议。

Azobenzene functionalized polyelectrolytes and polyamphiphiles are novel functional polymers with many interesting characteristics such as the photo-responsive properties based on the photo-induced cis-trans isomerization, the ability to build up ordered supramolecular structure, and the sensitivity to the environmental stimuli. The aim of this dissertation is to investigate the rules that control the formation of ordered structures from the azo polyelectrolytes and polyamphiphiles based on the supramolecular interaction, to explore the relationships between the material functionality and the supramolecular self-assembled structures at different levels, and to establish the methods for producing novel materials with potential applications in photonic and electronic areas.
