Controlled self-assembly of filled micelles on nanotubes.

Generating suspended single-walled carbon nanotubes across a large surface area via patterning self-assembled catalyst-containing block copolymer thin films.

Using self-assembled block copolymers as templates, catalytically active nanostructures with controlled size and space have been produced. A self-assembled polystyrene-b-polyferrocenylsilane thin film and monolayer of surface micelles of cobalt-complexed polystyrene-b-poly(2-vinylpyridine) are fully compatible with novolac-based conventional photoresists. Combining bottom-up self-assembly of ca...

A simple route to hierarchically assembled micelles and inorganic nanoparticles.

Earning their stripes: A hierarchical assembly of micelles composed of an amphiphilic diblock copolymer, poly(styrene)-block-poly(4-vinylpyridine) (PS-b-P4VP), were made by combining controlled evaporative self-assembly of the confined PS-b-P4VP toluene solution in a cylinder-on-Si geometry with spontaneous self-assembly of micelles. This method gave microscopic stripes of nanometer-sized PS-b-...

Self-assembly of Silicon Nanotubes

The growth of silicon nanotubes (SiNTs) by a dual-RF-plasma treatment technique is reported here. These SiNTs are vertically aligned and self-assembled from Si substrates at 500 °C by the use of Cu catalysts. Their diameters are ~50 to 80 nm with tubular wall thickness of ~10-15nm. Cu vapors were found partially filled inside the SiNTs. This is a novel technique that can convert bulk materials ...

Cascade Molecule−Particle−Molecule Self-Assemblies for Fabricating Narrowly Size-Distributed Polymeric Superparticles with a Bicontinuous Nanostructure

Broader developments of nanoscience and nanotechnology require complexly but regularly structured nanoparticles whose fabrications in turn pose a great challenge to nanoscience and nanotechnology. In this communication, we report a new and robust method with a clear mechanism for fabricating narrowly size-distributed superparticles with a bicontinuous inner structure. The processes for the fabr...
