We have demonstrated a new and efficient method for the synthesis and growth of well-dispersed perfect platinum nanocubes, employing a pair of low-resistivity fastened silicon (FS) wafers at 25 °C. The perfect Pt nanocubes deposited on the FS wafers exhibited an excellent catalytic activity and stability for methanol and ethanol oxidation.

A new adsorbent for removal of dye pollutants has been prepared by a simple one step solvothermal reduction method using non-toxic and cost-effective precursors. This adsorbent combines the advantages of magnetic nanoparticles and graphene, thus providing a novel platform for dye decontamination.

Self-consistent quantum simulations have shown it is possible to achieve a good transconductance and ballistic on–off ratio larger than 3, even at a channel length of 20 nm, by following design guidelines for electrostatic gate control necessary to extract the full potential of graphene for ultra high speed RF applications.

Field-effect transistors (FETs) have been fabricated using as-grown single-walled carbon nanotubes for the channel as well as both electrodes. The resulting FETs exhibited ION/IOFF ratios exceeding 106 and a maximum ON-state current of more than 13 μA.

A facile method for conversion of graphene oxide (GO) to reduced graphene oxide nanosheets (RGONS) and one-pot synthesis of Au nanoparticle–reduced graphene oxide nanosheet (Au–RGONS) hybrid materials is presented, based on sodium citrate as reductant and stabilizer.

Hexagram shaped gold particles and their analogues enclosed by high index facets with kinks have been successfully synthesized. The as-prepared gold particles exhibit a very high catalytic activity towards electrocatalytic oxidation of ascorbic acid due to their high density of step atoms and especially the kink atoms on the surface.
