There is provided a display including a display including a number of display cells (400). Each of the display cells (400) includes a first electrode (414), which is transparent and disposed over a front surface of a display cell (400). A second electrode (418) is disposed opposite the first electrode (414). A dielectric layer (404) is disposed between the first electrode (414) and the second electrode (418), and is patterned to create a plurality of recessed volumes (408). A fluid is disposed in a volume defined by the first electrode (414), the dielectric layer (404), and the recessed volumes (408). The fluid (410) comprises a dye of a different color from an adjacent display cell (400). Charged particles (412) are disposed within the fluid (410). The display also includes a display driver configured to pack the charged particles (412) against the front of the display cell to create a first optical state, to pack the charged particles (412) against the back of the display cell (400) to create a second optical state, or to pack the particles into the recessed regions (408) to create a third optical state.

An electrophoretic particle salt that includes a cationic electrophoretic particle and an anionic group ionically associated with the cationic electrophoretic particle is employed in an electrophoretic display. A spacer group chemically bonds a cationic moiety to a surface of the electrophoretic particle. A method of making the electrophoretic particle salt includes particle surface modification, nucleophilic substitution to create an interim salt and anion exchange. The electrophoretic particle salt has an ionization constant that favors dissociation into a positively charged electrophoretic particle and the anionic group in a nonpolar medium. The electrophoretic display includes a pair of electrodes and a dispersion of the electrophoretic particle salt in a nonpolar medium in a gap between the pair of electrodes.

Crystal growth performed in situ facilitates interconnection of prefabricated nano-structures. The nano-structures are immersed in a growth solution having a controllable saturation condition. Changing the saturation condition of the solution modifies a size of the immersed nanowires. The solution includes a solute of a nano-structure precursor material. The saturation condition is changed to one or both etch material from a surface of the nano-structures and initiate crystal growth on the nano-structure surface. A nano-structure interconnection system includes the growth solution and equipment to deposit the prefabricated nano-structures on a substrate. An interconnected structure includes a plurality of nano-structures disposed on a substrate in a cluster and a liquid phase-grown crystal lattice on surfaces of the nano-structures to form physical interconnections between the plurality. An ink formulation includes the plurality of nano-structures suspended in the growth solution.

An electrophoretic cell and methods of switching an electrophoretic cell and moving charged species in an electrophoretic cell employ differential electrophoretic mobilities and a time-varying electric field. The methods include providing first and second charged species that are oppositely charged and have different mobilities. The method of switching further includes inducing a net motion of both of the charged species using the time-varying applied electric field. The induced net motion results in either the first charged species being moved toward the electrode and the second charged species remaining essentially motionless or both of the charged species being moved toward the same electrode. The electrophoretic cell includes the first and second charged species with opposite charge and different mobilities, and further includes the time-varying applied electric field that provides the net motion of the charged species.

A self-aligning nanowire includes a nanowire portion and an aligning member attached to the nanowire portion. The aligning member interacts with another aligning member on an adjacent self-aligning nanowire to align the nanowires together. A method of aligning nanowires includes providing a plurality of the self-aligning nanowires, suspending the plurality in a carrier solution, and depositing the suspended plurality on a substrate. An ink formulation includes the plurality of suspended self-aligning nanowires in the carrier solution. A method of producing the self-aligning nanowire includes providing and associating the nanowire portion and the aligning member such that the nanowire produced is self-aligning with another nanowire.
