An ordered nanostructure formed by epitaxial crystallization of a semicrystalline block copolymer has been used as a patterned template for the selective deposition of thermally evaporated gold nanoparticles, resulting in a long-range order in the positioning of the functional nanoparticles, guided by the order of the nanostructured matrix.

A novel CdSe QD quantum dot (QD) sensitized Au/TiO2 nanocomposite has been synthesized and studied for photoelectrochemical applications. Au nanoparticles significantly enhance the photocurrent, which is tentatively attributed to increased light absorption of the CdSe QDs as a result of light scattering by Au nanoparticles.

A hybrid nanowire–superconductor system has been controlled via a mechanism of hot-electron injection. The experiment allows us to obtain new estimates of unknown thermal and electrical parameters of InAs nanostructures.

A miniature droplet reactor has been built on nanoparticle-derived superhydrophobic pedestals, which provide a confined space and the capability to perform a series of aqueous phase chemical reactions on a small scale. Due to the low-adhesive properties of the substrate, reaction products in liquid or solid states can be collected effectively, providing a promising way to harvest valuable products prepared in limited amounts.

TiO2/graphene composite photocatalysts have been prepared by a simple liquid phase deposition method using titanium tetrafluoride and electron beam (EB) irradiation-pretreated graphene as the raw materials, and their photocatalytic properties studied.

A hybrid silicon-carbon nanostructured composite with large area has been fabricated in a simple fashion using a conventional sputtering system, and when employed as the anode in lithium ion batteries gives a high specific capacity and good capacity retention.

The absorption of one atomic layer graphene can be saturated at quite low excitation intensity and gives a remarkably large modulation depth of 65.9%. Picosecond laser pulses (1.23 ps) can be generated using monolayer graphene as a saturable absorber. A monolayer graphene mode-locked laser shows better pulse stability and higher output energy.

We revealed a linear relationship between the red-shift of the near-band-edge (NBE) emission exciton energy and the strain-gradient in elastically bent CdS nanowires.

Using a newly-developed approach, we have achieved the direct growth of a nanographene film on a 4-inch glass wafer. The transmittance and conducting properties of films deposited on glass and quartz substrates have been studied.
