This invention provides a process for improving the field emission of an electron field emitter comprised of an acicular emitting substance such as acicular carbon, an acicular semiconductor, an acicular metal or a mixture thereof, comprising applying a force to the surface of the electron field emitter wherein the force results in the removal of a portion of the electron field emitter thereby forming a new surface of the electron field emitter.

Process for improving the emission of electron field emitters

This invention relates to single-wall carbon nanotube/polymer composites, a process for the production of such, and their use as fibers, films and articles.

Single-wall carbon nanotube-polymer composites

Patterned ion-bombarded carbon electron emitters and the processes for producing them. The electron emitters are produced by forming a layer of composite of carbon particles and glass on a substrate then bombarding the composite with an ion beam. The electron emitters are useful in field emitter cathode assemblies which are fabricated into flat panel displays.

Past-deposited carbon electron emitters

Metal-oxygen-carbon field emission electron emitter compositions and field emission cathodes made thereform are disclosed. A process for making metal-oxygen-carbon whisker field emitters is also provided, wherein a metal substrate (e.g., tungsten wire) is coated with an organic polymer and heated to a temperature of from about 1100&deg; C. to about 1550&deg; C. in an inert atmosphere for about 15 minutes to about two (2) hours. The heating temperature can be reduced when heating is carried out in the presence of a catalyst, such as a copper-nickel alloy catalyst. The emitter compositions and field emission cathodes of the invention are useful in vacuum electronic applications and devices (e.g., flat panel displays).

Metal-oxygen-carbon field emitters

A method for introducing a biological substance into a target which utilizes particles having a substantially pure carbonaceous surface to which is associated a biological substance wherein the particles are sufficiently small to penetrate the target without killing the target is described.

Method for introducing a biological substance into a target

A three-dimensional arrangement of carbon fibers made from mesophase pitch are used to reinforce polymer resins to form a composite material. The composite material exhibits high thermal conductivity values on all axes through the composite.
