Abstract: A rewriteable diffraction grating contains first nanoparticles and second nanoparticles. Each first nanoparticle is configured and arranged to generate one or more charge carriers in response to a write beam. Each second nanoparticle is configured and arranged to substantially alter its response to light from a read beam upon receiving one or more charge carriers from the first nanoparticles. The second nanoparticles are disposed in proximity to the first nanoparticles to permit charge carriers generated by the first nanoparticles to interact with the second nanoparticles.

Abstract: Described is a method for preparation of carbon nanotubes (CNTs) with medium to low-site density growth for use in field emission devices (FEDs). The method involves the deposition of a non-catalytic metal layer (interlayer), preferably a metallic conductor, onto the surface of a substrate, prior to the deposition of a catalytic layer (overlayer). The interlayer allows for only partial (sparse) growth of CNTs on the substrate, and helps to prevent resist layer “lift-off” when photolithographic processing is employed.

Abstract: A method of making a carbon nanotube structure includes forming a plurality of carbon nanotubes and contacting the carbon nanotubes with a polymer. A solid composition is formed from the carbon nanotubes and polymer and then shaped. For example, the solid composition can be shaped into an elongated structure such as a filament, wire, rope, cable, and the like. In at least some instances, at least some, or all, of the polymer is removed from the solid composition after it is shaped.

Abstract: The invention includes providing a display by moving a colorant particle, having an electric charge, inside a channel of a body in a direction that is substantially parallel to a direction of extension of the channel and a direction of incoming illumination rays. The colorant particle can be moved between a position at a bottom of the channel and at a top of the channel by the force of an electric field generated by a charge at the bottom of the channel.

The invention is also not limited to covering displays, and also covers at least print media, wherein colorant particles are locked at appropriate locations within the channels, either temporarily or permanently.

Abstract: The invention concerns a method and apparatus that provides predetermined and user determined areas on an electronic whiteboard which provides the user with various computer-related functions. In particular, a communication server would monitor the hot zones for detection of the users electronic pen. If the communication server detects the users electronic pen in the hot zone area for longer than a predetermined time, for example two seconds, then the communication server would perform the function defined by that particular hot zone. A plurality of hot zones may be defined and fixed as part of either the electronic whiteboard environment, or they may be relative so that a user can define particular hot zone areas, including their location, content and function. These hot zone areas may be moved anywhere in the electronic whiteboard area.
