It was found that the component of the reaction system has a significant influence on the formation of hollow Ag2S spheres. The possible formation mechanism of the hollow Ag2S spheres in the emusion system was also discussed.展开更多

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
