An ordered array of Ni submicrotubes with up to 35 ìm in length has been successfully prepared by electrodeposition in the pores of alumina membrane modified with methyl-?-diethylenetriaminopropyl-dimethoxysilane...An ordered array of Ni submicrotubes with up to 35 ìm in length has been successfully prepared by electrodeposition in the pores of alumina membrane modified with methyl-?-diethylenetriaminopropyl-dimethoxysilane as pore-wall-modifying agent. Furthermore, using the array of Ni submicrotubes with an alumina membrane support as a "second-order-template", the concentric composite structure of Co wires filling Ni submicrotubes was prepared by electrodeposition method. Magnetization measurements on the array of the Ni submicrotubes and the concentric composite structure of Co wires filling Ni submicrotubes revealed different uniaxial magnetic anisotropy.展开更多

The ordered structure arranged by the uniform pores and the pore-pore interconnectivity through the window channel is confirmed by SEM characterization. UV-Vis-near IR absorption experiment result reveals that the wavelength at the stop band peak is tunable within the whole visible spectrum via simply altering some parameters such as pH value and light incidence angle. This finding allows to design frequency-tunable photonic band gap materials.展开更多
