Abstract: Nanoparticles in a colloid are purified, with the colloid including a fluid, unwanted matter, and the nanoparticles to be purified. An electric field is applied that is substantially spatially uniform over a distance that is at least equal to a characteristic dimension of the nanoparticles, so that at least some of the nanoparticles move towards at least one collection surface as a result of the force arising between their electrical charge and the electric field, whereupon nanoparticles are collected on said at least one collection surface. The collection surface(s) may be one or more electrodes to which a voltage potential is applied. The collected nanoparticles are then removed from the collection surface, e.g., by dispersing them into another fluid.

Abstract: A multi-stable memory or data storage element is used in crosspoint data-storage arrays, as a switch, a memory device, or as a logical device. The general structure of the multi-stable element comprises a layered, composite medium that both transports and stores charge disposed between two electrodes. Dispersed within the composite medium are discrete charge storage particles that trap and store charge. The multi-stable element achieves an exemplary bi-stable characteristic, providing a switchable device that has two or more stable states reliably created by the application of a voltage to the device. The voltages applied to achieve the “on” state, the “off” state, any intermediate state, and to read the state of the multi-stable element are all of the same polarity.

The multi-stable element is stable, cyclable, and reproducible in both the “on” state and the “off” state. The storage medium has a relatively high resistance in both its on and off states.

Abstract: High density circuitry and metallic patterns are grown from polymer that has been patterned using a contact molding process. The patterned polymer is either intrinsically seedable or treated to make it seedable, e.g., it may be seeded with metallic seed ions, such as Pd ions. The patterned polymer is placed in an electroless deposition bath, with metal being plated onto its surface. Using these methods, metal (e.g, copper) may be deposited onto substrates of either organic or inorganic dielectric materials. The dielectric materials may comprise epoxy resins, ceramics, semiconductors (Si), glass, and silicon oxide.

Abstract: Multifunctional electroactive copolymers are provided. The copolymers may be A-B-A triblock copolymers, brush-type graft copolymers, or variations thereof. In a preferred embodiment, the copolymers are “dual use” in that they comprise both a light emitting segment and a charge transport segment. Methods of synthesizing the novel electroactive copolymers are provided as well, as are opto-electronic devices, particularly LEDs, fabricated with the novel copolymers.
