We reported an electrochemically assisted Mechanically Controllable Break Junction approach to investigate single molecule junction conductance. Two probe molecules, benzene-1,4-dithiol and 4,4'-bipyridine were used to test the feasibility of our method.

We demonstrate a simple and controllable way to synthesize largearea, few-layer graphene on iron substrates by an optimized chemical vapor deposition method using a mixture of methane and hydrogen. An appropriate temperature and cooling process were found to be very important in the synthesis of highly crystalline few-layer graphene. The resulting materials were used to fabricate field-effect transistor devices.

Silver nanowire transparent electrodes with low sheet resistance and low surface roughness have been fabricated by mechanical pressing after rinsing at room temperature. This technique makes it possible to fabricate silver nanowire transparent electrodes on heat-sensitive plastic substrates.

Monodisperse Fe3O4 nanoparticles and M–Fe3O4 (M = Au, Ag, Pt, Pd) heterostructures have been fabricated by a thermal decomposition method using an iron oleate complex as a precursor. This method provides a way of achieving size tunability and monodispersity, and the resulting particles show excellent magnetic and optical properties which open the door for biomedical and environmental applications.

Magnetically recyclable Au/Co/Fe triple-layered core–shell nanoparticles (NPs) around 10 nm in diameter have been successfully synthesized via a one-step in situ reduction procedure. The catalytic activity of Au/Co/Fe NPs for the hydrolytic dehydrogenation of ammonia borane is much higher than those of corresponding monometallic or bimetallic NPs.

The kinetics of the graphene edge folding process have been investigated using molecular dynamics (MD) simulations. The energy diagram of a single-layer graphene edge folding process shows the initial, transition and final state energies, where the bottom left and the right figure show the initial and the final (with the folded edge) atomic structure, respectively.

Multifunctional FeCo–graphitic carbon nanocrystals have been used for drug delivery, in vivo imaging and tumor-selective nearinfrared photothermal therapy. The therapeutic system provides a highly effective treatment of 4T1 tumors in mice.

High-resolution transmission electron microscopy shows a surface dislocation slip for a <111> single crystalline gold nanowire (diameter ~6 nm) under tensile deformation, which was subsequently confirmed by molecular dynamics simulations.
