A collage of self-assembled structures formed via molecular simulation from anisotropic "patchy particles." The foreground is a rendering of an icosahedron formed from nanoparticles with two attractive equatorial rings. The background is a rendering of a honeycomb lattice of nanoparticles with triangular attractive patterning.

Zinc dendritic structures formed by electrodeposition on Cu substrates using a mixed solution of ZnO powders and NaOH at room temperature. The Cu substrate was pretreated to form a layer of nanowires before it was used to form the Zn dendritic structures. Various forms of nanostructures can be formed by controlling the electroplating conditions. (Magnification: 1,300x)

Two-dimensional carbon nanostructures grown on a Ga droplet using microwave-enhanced chemical vapor deposition. The orientation of the curved nanosheets is determined by the local electrical field direction. (Magnification: 13,000x)

A color enhanced scanning electron micrograph of ZnO grown in aqueous solution by homogeneous precipitation. The crystal morphology of the zinc oxide was controlled by using a sequential nucleation and growth process in which simple morphology crystals were grown and then subjected to further growth in the presence of different growth modifiers.
