Isolated graphene nanoribbons with resistivity less that may be achieved with e-beam lithography can be easily produced in ambient air using atomic force microscopy-based electrostatic nanolithography (AFMEN). Reduction of fluorine from graphene fluoride occurs in non-uniform electric filed of magnitude 1每2 V/nm.

Combining neutron reflectometry and nanolithography, the detailed structure of a self-assembled organic thin film deposited on a regularly patterned silicon surface at the solid每liquid interface is presented. The detailed structure of the substrate and film, inside and outside of the 100 nm deep holes is revealed with sub-nanometer resolution.

A novel strategy to improve the upconversion luminescence (UCL) of NaYF4:Yb3+,Er3+ upconversion nanophosphors (UCNPs) is presented, combining the near-field coupling of the surface plasmon resonance (SPR) of a porous silver film and the far-field coupling of poly(methyl methacrylate) photonic crystals with the UCNPs. A maximum UCL enhancement of 60-fold was obtained and furthermore the porous structure of the silver film can suppress local thermal effects and increase transparency.

Composition-dependent photoconductivity in ternary CdSxSe1-x nanobelts is measured using optical pump-terahertz probe spectroscopy. Binary CdS and CdSe are observed to have much shorter carrier lifetimes than those of ternary alloys whilst ternary CdSxSe1-x nanobelts present much higher photoconductivity than those of binary nanobelts.

In the light of the current problems of silver nanoparticles (Ag NPs) in terms of antibacterial performance, we designed a trimetallic core/shell nanostructure with AgPt alloy nanodots epitaxially grown on gold nanorods (Au@PtAg NRs) as a potential antibacterial agent. Such architecture is not only found to be an effective way to incorporate the requirements of both high antibacterial activity and high chemical stability at the same time, but also promises great potential in utilizing additional plasmonic effects in the fight against pathogenic bacteria, including the challenge of increasing severity of multidrug resistance.

It is demonstrated that sizing of single Fe3O4 nanoparticles can be performed by two independent electrochemical routes〞cathodic and anodic particle coulometry. This allows precise nanoparticle size information and verification of the obtained results solely by electrochemical methods.

In an attempt to achieve graphene sheets with a highly restored 羽-conjugated structure for use in inkjet-printed electronics, we present a ※weak oxidation每vigorous exfoliation§ strategy for tailormade graphene oxide with a more intact carbon plane and suitable size. Its inkjet-printed patterns show an ultrahigh conductivity of ~420 S﹞cm每1, which is tens of times higher than previously reported results. Furthermore, printed all-carbon transistors with excellent performance are demonstrated.
