The output of an ultrasonic wave driven nanogenerator (NG) has been shown to depend on the excitation conditions and geometry. Incidence angle tests indicate that the effective area of an NG determines the amount of power that can be generated. The output power of an NG is also directly related to its distance from the ultrasonic source.

Address correspondence to

Graphene oxide sheets have been successfully decorated with aerosol Ag nanocrystals at room temperature using electrostatic force directed assembly. Ripening of Ag nanocrystals was observed after annealing the Ag-graphene oxide hybrid structure in Ar. Schematics (top panel) are not to scale.


Direct Growth of Enclosed ZnO Nanotubes

Nano Res (2009)2:201-209

Address correspondence to

Single-crystal enclosed ZnO nanotubes can be grown by a direct wet chemical approach. A concave growth front can either remain unaltered or undergo a concave-to-convex transformation, leading to the growth of solid nanorods and/or hollow nanotubes.

Address correspondence to

A phase transition from an ordered packing arrangement with fourfold symmetry at negative bias to a random arrangement at positive bias was observed for a self-assembly of Lu2Pc3 molecules. Molecular switching behaviour by a bias-polarity-induced fl ipping process was demonstrated and confi rmed by the shift of the peak in dI/dV versus V curves for individual Lu2Pc3 molecules when the voltage scanning direction was reversed.

Address correspondence to Dongyuan Zhao,; Bo Tu,

A simple approach for hierarchically porous monolithic materials with different mesostructure is demonstrated by organic organic coassembly of the precursors on the 3-dimensional interconnected network of PU foam scaffold. The strategy is also a good candidate for mass production of mesostructured materials especially for the coassembly process in which the gas-liquid interface is required.

By means of scanning tunneling microscopy (STM) imaging and manipulation we investigate the morphology and anchoring of a specially designed Lander molecule on Cu(110) and Au(111) substrates. We conclude that Au(111) may be the more suitable substrate for the self-assembly of this Lander molecule since the weaker molecule¨Csubstrate interaction will be beneficial for the formation of ordered molecular architectures mainly driven by intermolecular interactions.
