High lateral resolution imaging with sharpened tip of multi-walled carbon nanotube scanning probe

Article Abstract:

A tip sharpening process for multiwalled carbon nanotube (MWCNT) scanning probes is reported along with demonstrating its application in high lateral resolution imaging. The study shows that the coupling of the sharpening method and the superior mechanical properties of MWCNT results in a highly stable scanning probe with universal applications, from high lateral resolution to high aspect ratio imaging.

The [2+1] cycloadditions of dichlorocarbene, silylene, germylene, and oxycarbonylnitrene onto the sidewall of armchair (5,5) single-wall carbon nanotube

Article Abstract:

An exploration of the reaction pathway and site selectivity or the [2+1] cycloadditions of dicholorocarbene and oxycarbonylnitrene onto the sidewalls of single-wall nanotube (SWNTs) is carried out. In addition, it is predicted that whether such [2+1] cycloaddition chemistry can be extended to other reactants, such as silylenes and germylenes, on the sidewalls of SWNTs.

Preparation and characterization of multiwalled carbon nanotube- supported platinum for cathode catalysts of direct ethanol fuel cells

Article Abstract:

Two preparation methods for multiwalled carbon nanotube supported platinum nanoparticle catalysts as cathode catalysts in direct ethanol fuel cells (DMFCs) are presented. The XRD, TEM and HRTEM characterizations reveal that the high and homogeneous dispersion of Pt particles for the Pt/ multiwalled carbon nanotubes (MWNTs) can be prepared by the EG method.
