    摘要: Electron field emission devices (cold cathodes), vacuum microelectronic devices and field emission displays which incorporate cold cathodes and methods of making and using same. More specifically, cold cathode devices comprising electron emitting structures grown directly onto a substrate material. The invention also relates to patterned precursor substrates for use in fabricating field emission devices and methods of making same and also to catalytically growing other electronic structures, such as films, cones, cylinders, pyramids or the like, directly onto substrates.

    摘要: Methods and apparatus provide for spray drying a liquid product into a dried powder without applying heat, including: forming a slurry including a liquid solvent, a carrier, and an active ingredient; applying an electrostatic charge to the slurry; atomizing the charged slurry to produce a plurality of electrostatically charged, wet particles; suspending the electrostatically charged, wet particles for a sufficient time to permit repulsive forces induced by the electrostatic charge on at least some wet particles to cause at least some of such particles to divide into wet sub-particles; and continuing the suspending step, without the presence of any heated drying fluids, for a sufficient time to drive off a sufficient amount of the liquid solvent within most of the wet particles to leave a plurality of dried particles (the powder), each dried particle containing the active ingredient encapsulated within the carrier.
