On Ag(110), 2,6-naphthalenedicarboxylic acid (NDCA) molecules self-assemble to form extended one-dimensional (1-D) assemblies, which cross the step edges and have lengths of several hundred nanometers. On Cu(110) and Ag(111), in contrast, step-crossing is not observed.

The (M)-enantiomer of hexanitrostilbene docks in an electrostatic nest formed on a graphene sheet with specific boron and nitrogen substitution doping (top). The molecule does not bind well to the same nest on the bottom of the graphene sheet, which matches the opposite enantiomer. The presence of the docked molecule and its chirality can be recognized once the system is vibrated at different normal frequencies that become selectively modified by the docking.

A simple and efficient biosynthesis method has been developed to prepare easily harvested, highly fluorescent and protein-capped cadmium telluride (CdTe) quantum dots (QDs) using yeast cells. The biosynthesized CdTe QDs show excellent biocompatibility, and the in situ bio-imaging of yeast cells is easily achieved.

Peculiar outer rings with concentric inner holed rings have been formed by aluminum droplet epitaxy, and a mathematically simple empirical equation established in order to examine the edge profiles of the outer rings.

Polymer/nanocrystal (NCs) composites with emission over the whole visible range (400–800 nm) have been obtained by changing the size and amount of the NCs with the aim of realizing the controllable regulation of the emitting color. A pure white-light emitting material can be prepared using NCs with emission wavelength of 559 nm and the mechanism of the white-light emission process is discussed.

Gold seed particles provide the most highly controlled nanowire growth. We show that the use of different generation and deposition methods for the gold seed particles affects nanowire growth to some extent. The time before the nanowires start to grow varies depending on the fabrication method of the seed particles.

Corrugated silicon nanocone arrays with strong antireflection and superhydrophobic properties have been fabricated. The effective thickness of the transition layer is enlarged by the compound silicon pillars, which can avoid strict requirements such as sharp conical shape and high aspect ratio.

GaN nanowires can be grown by molecular beam epitaxy either catalyst-free or catalyst-induced by means of Ni seeds. Under identical growth conditions, both types of GaN nanowires are of wurtzite structure elongated in the Ga-polar direction and are constricted by planes. However, the catalyst-induced nanowires contain many more basal-plane stacking faults and their photoluminescence is weaker. These differences can be explained as effects of the catalyst seeds.
