Carbon nanotubes (CNT) complexes (RNA-wrapped, oxidized double-walled carbon nanotubes) were endocytosed by capture in clathrin-coated vesicles, as revealed by clear co-localization with both clathrin and transferrin. CNT complexes were also found in early endosomes, which was confirmed by co-localization with early endosome antigen (EEA). CNT complexes were not sorted for recycling back to the cell membrane (via fast recycling endosomes), as co-localization with Rab 4 was not observed. Instead, the overlapping of CNT complexes with both LAMP2 antibody and LysoTracker® marker indicated their sequestration in lysosomes. CNTs were also found within vesicles of the secretory pathway (Rab 11-positive vesicles), which for the first time suggests an exact route for their exocytosis.

A carbon nanotube has van der Waals interactions with both the substrate it is on and the atomic force microscope (AFM) tip that is used to image it. The deformation due to such interactions affects the measurement of the nanotube dimensions using AFM. The laser in the background represents Raman microscopy measurement of carbon nanotube (CNT) diameter.

The atomic structures and electronic and optical properties of the C60/CuPc heterojunction have been studied. The lying-down configurations facilitate interface charge transfer and yield larger open voltages.

Epitaxial growth of graphene, including homo- and hetero-epitaxy on graphite and SiC surfaces at a low temperature, has been accomplished by remote plasma-enhanced chemical vapor deposition. This graphene epitaxy technique provides a new strategy toward large-area and high-quality graphene with controlled layer thickness.

A three-dimensional and recyclable CdS nanoparticle每carbon nanotube (CNT) hybrid sponge photocatalyst has been fabricated. This hybrid sponge can remove dye molecules efficiently by simultaneous adsorption of organic molecules (by the CNT sponge) and photocatalytic decomposition (by the CdS nanoparticles).

Controlled self-assembly of ~2 nm gold nanoparticles (NPs) to afford one-dimensional (1D) nanochain, two-dimensional (2D) nanobelt and three-dimensional (3D) nanocomet architectures has been achieved by kinetically controlling the diffusion of gold NPs in solution. This study demonstrates that the surface effect of ultrasmall nanocrystals (nanoclusters) is critical in the construction of complex self-assemblies.
