Low-pressure chemical vapor deposition and stacked multiple transfer techniques have been developed to achieve high-density aligned carbon nanotubes and high-performance submicron nanotube field- effect transistors have been further demonstrated. This platform holds great potential for high performance nanoelectronics and analog/RF applications.

Water-soluble monodisperse single core nanocrystals (e.g., iron oxide nanoparticles and semiconductor quantum dots) as well as magnetic–optical hybrid nanoparticles have been synthesized using the amphiphilic copolymer poly(ethylene oxide)-b-poly (γ-methacryl- oxypropyltrimethoxysilane) (PEO-b-PγMPS) by enhancing ligand exchange through aging. Multi-core clustered nanoparticles have been generated using the same copolymer by minimizing the ligand exchange by not aging. The resulting multi-core clustered nano- particles exhibit enhanced magnetic and optical properties, and have greater capacities for biomedical applications.

Using in situ scanning tunneling microscopy (STM) and angle- resolved photoemission spectroscopy (ARPES), we show that ultrathin Sb2Te3 films grown layer-by-layer by molecular beam epitaxy (MBE) on Si(111) are atomically smooth, single-crystalline topological insulators.

The quantitative analysis of low temperature micro-photoluminescence spectra of around 100 nanowires reveals that each nanowire exhibits its own individual spectrum. A significant fraction of nanowires exclusively emits at energies corresponding to either surface- donor-bound or free excitons, demonstrating that optical properties of individual nanowires are determined by the presence and location of a few impurity atoms alone.

Direct laser patterning of superhydrophobic silicone nanofilaments is investigated. Processing with a focused laser beam at 355 nm allows selective removal of the coating which leads to contrasting wettabilities of the substrate.

High capacity and remarkable rate capability can be achieved with Co3O4 nanowire array electrodes by uniformly loading Ag nanoparticles onto the surfaces of the Co3O4 nanowires via the silver-mirror reaction.
