Abstract:
Characterization of composition and structure is crucial to understanding the properties and performance of nanomaterials. For nanowires and nanotubes, determining radial compositional and structural modulations is particularly challenging. Here we use a focused ion beam (FIB) lift-out technique to show that Cu-Ni core/shell nanowires fabricated by template synthesis are characterized by large, high purity (>99 atom %) copper grains surrounded by much smaller, high purity (>99 atom %) nickel grains.

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
