Hierarchical structured Ni nanoring and hollow sphere arrays by morphology inheritance based on ordered through-pore template and electrodeposition

Article Abstract:

The fabrication of micro/nano-hierarchical Ni ordered nanostructured arrays is shown by electrochemical deposition on the ordered alumina through-pore template induced by solution-dipping the colloidal monolayer. The micro/nano-hierarchically structured arrays have shown good magnetic properties and can be used in the fields of catalysis, magnetics, optoelectronics, surface-enhanced Raman scattering (SERS), and new nanodevices.

Effect of Ni and Pd on the geometry, electronic properties, and active sites of copper clusters

Article Abstract:

First-principle methods are used to investigate the effect of Ni and Pd atoms on the geometry, electronic properties and active sites of copper clusters. The interaction between impurities and copper atoms can modify the chemical hardness and active sites of doped copper clusters markedly inducing directionality in the reactivity, which is relevant to the behavior of catalysts as well as in the growth of metallic films.
