Networks of pristine high quality single walled carbon nanotubes (SWNTs), the SWNTs after Ar-plasma treatment and carbon nanobuds (CNBs) have been tested for ethanol vapor sensing. The importance of defects in the carbon nanomaterials was demonstrated.

Co3O4 hollow spheres have been obtained by a one-pot and low hydrothermal temperature synthesis method using carbonaceous microspheres as sacrificial templates. These hollow spheres show excellent electrochemical performance in electrochemical supercapacitors.

We find evidence for structural feedback in graphene growth on copper foil—the copper surface becomes faceted under the graphene and in turn these facets influence the orientation of graphene from the onset of growth. Despite the differences in symmetry between the copper surface and graphene and the weak interaction between the two, the preferred orientations of the graphene grains are determined by the crystallography of the copper surface and hence an epitaxial relationship is found.

Fluorescence-enhancing microarrays on plasmonic gold films have been developed for multiplexed cytokine detection with up to three orders of magnitude higher sensitivity than on conventional nitrocellulose, glass substrates and enzyme-linked immunosorbent assay (ELISA). A panel of six cytokines (Vascular endothelial growth factor (VEGF), Interleukin 1β (IL-1β), Interleukin 4 (IL-4), Interleukin 6 (IL-6), Interferon γ (IFN-γ), and Tumor necrosis factor (TNF)) were detected in the culture media of cancer cells. This approach could pave a new way for better proteomic analysis and disease diagnosis.

An easy and effective solution based procedure for the synthesis of noble metal (both Au and Ag) tipped semiconductor nanomaterials is demonstrated where the metal precursors are dissolved in water and the semiconductors in an organic medium, exploiting the phase transfer and reducing capability of suitably chosen ligands.

Pentacene molecules preferentially adsorb on the face-centered cubic (fcc) regions of graphene/Ru(0001) in the initial stage. At high coverage, we have successfully controlled the molecular assembly from amorphous, local ordering, to long-range order by optimizing the deposition rate and substrate temperature. Intrinsic molecular orbitals are clearly resolved by scanning tunneling microscopy (STM) in each assembly structures due to the decoupling effect of a single graphene layer.

A small degree of graphene surface functionalization, using diazonium salts with electron-withdrawing and electron-donating functional groups, is sufficient to induce p-type doping without a decrease in conductivity at the neutrality point.
