Helical superstructures of fullerene peapods and empty single-walled carbon nanotubes formed in water
Article Abstract:
The discovery that aqueous dispersions of empty single-walled carbon nanotubes (SWNTs) and of fullerene peapods prepared by using a carbon nanotube solubilizer trimethyl-(2-oxo-2-pyrene-1-yl-ethyl)-ammonium bromide form helical carbon nanotube superstructures in the shapes of rings, irregular rings, lassos handcuffs, catenanes, and pseudorotaxanes is presented. The mechanism of the superstructure formation is discussed in relation to the unique characteristics of stiff polymer chains with the aid of an off-lattice Monte Carlo simulation.

Optical trapping of a growing water droplet in air
Article Abstract:
A demonstration of the optical trapping of a water droplet in the gas phase with a converged laser is presented. The results reveal that the optical trapping is useful for observing the dynamic instability of micrometer-scale systems.
