The disclosure relates to processes for the electrochemical modification of electron emitting materials such as carbon nanotubes. The processes improve the oxidation resistance of the electron emitting materials when they are fired in an oxygen-containing atmosphere such as air. The disclosure also relates to the preparation of cathodes or cathode assemblies, for use in a field emission device, wherein are contained an electron field emitter made from such electron emitting material.

Process for improving the oxidation resistance of carbon nanotubes

This invention relates to the electrochemical deposition of carbon nanotubes ('CNTs') on a substrate using an electrochemical cell. A dispersion of a complex of CNTs and an anionic polymer is neutralized and thereby caused to deposit on the anode plate of the cell.

Method for the electrochemical deposition of carbon nanotubes

The present invention relates to electrically conductive polymer compositions, and their use in organic electronic devices. The electrically conductive polymer compositions include an intrinsically conductive polymer having at least on monomer unit derived from Formula I: where:

Electrically conductive polymer compositions

The present invention relates to electrically conductive polymer compositions, and their use in organic electronic devices. The electrically conductive polymer compositions include an intrinsically conductive polymer having at least one monomer unit derived from Formula I: where:

Described herein is a method for the photo-induced reduction/oxidation of carbon nanotubes, and their use in photochemical cells and in electrochemical cells for the generation of hydrogen.

Photo-induced reduction-oxidation chemistry of carbon nanotubes

Carbon nanotubes have been reversibly and readily oxidized and reduced with common chemicals in solution, thereby allowing the nanotubes to be used as catalysts for chemical reactions and as stable charge storage devices.

Carbon nanotubes as catalysts in redox reactions

Nucleic acid molecules in a stabilized solution such as single stranded DNA and RNA were able to disperse high concentration of bundled carbon nanotubes into aqueous solution.

Dispersion of carbon nanotubes by nucleic acids

Carbon nanotube-nucleic acid complexes

Reversible oxidation of carbon nanotubes

Metallic nanoparticles coated with a mixed monolayer with well defined thickness or length are prepared. The mixed monolayer comprises a capture coating component useful for the specific capture of materials and a shielding coating component for elimination of non-specific binding of materials to the capture component.

Ethylene glycol monolayer protected nanoparticles

Carbon nanotubes dispersed by a stabilized solution of nucleic acid molecules formed separated nanotube-nucleic acid complexes and were separated according to standard chromatographic methods, including gel electrophoresis, two phase solvent systems and ion exchange chromatography.
