The result TiO2 nanorings were characterized by FE-SEM and XRD. Results showed that the inner diameter of the TiO2 nanorings matched size of the polystyrene nanospheres used, and the thickness with nanometer size depended on that of the TiO2 gel coated on the PS surface.展开更多

A two-step anodic oxidation of high purity aluminum was used to fabricate porous alumina templates with graded pore sizes. Based on the templates, metal silver graded nanowires were obtained by electrochemical deposition. SEM and TEM results show that the resulted metal silver nanowires have obvious graded diameters with gradient ranging from about 12 to 31 nm along the nanowire direction, and are single-crystalline with a preferential growth along <100> direction.展开更多
