In one embodiment, a display element includes a first electrode, a second electrode, and a dielectric layer on the second electrode. The dielectric layer has recess regions therein. The display element includes an opaque layer on the second electrode within each recess region and a fluid with colorant particles between the first electrode and the second electrode.

A method for depositing a seed layer for a controllable electric pathway on a substrate includes selectively dispensing a seed material from an inkjet material dispenser onto said substrate.

System and method for depositing a seed layer

This disclosure relates to a system and method for fabricating and using a superlattice. A superlattice can be fabricated by applying alternating material layers on a ridge and then removing some of the alternating layers to expose edges. These exposed edges can be of nearly arbitrary length and curvature. These edges can be used to fabricate an array of nano-scale-width curved wires.

Fabrication and use of superlattice

Subject matter includes a fuel cell with a catalytic combustor seal and related methods. The catalytic converter is positioned to come in contact with a fuel after the fuel has traversed a path over an intended electrode and the fuel is catalytically converted before the fuel can come in contact with an unintended electrode.

Fuel cell with catalytic combustor seal

A method of plating a substrate including coating a substrate surface, laser-treating a region of the coated surface, and plating the region.

Laser enhanced plating for forming wiring patterns

A fuel cell includes one or more fuel cell assemblies. Each of the fuel cell assemblies has an electrolyte having a length, an anode having a length and disposed on one side of the electrolyte, and a cathode having a length and disposed on the same or the other side of the electrolyte. The fuel cell further includes a plurality of current collectors. Each of the current collectors is substantially embedded within, and continuously extends substantially the respective length of at least one of the electrolyte, anode and cathode.

Fuel cell with embedded current collector

An emission device includes a plurality of electron emitter structures of varied geometry that have a conducting layer deposited thereon. The conducting layer has openings located at tunneling sites for each of the electron emitter structures. The tunneling sites facilitate electron emissions from each of the varied geometry electron emitter structures upon voltage biasing of the conducting layer relative to the electron emitter structures.

Emission device and method for forming

A method for creating a mandrel for electroforming orifice sheets with tapered bores is described. The method uses photo-imagable polymer or photoresist to create the desired profile. This is followed by electroforming a parent mandrel over which a mandrel-quality sheet of glass is melted. An array of pillars with defined location and shape is formed with a desired profile for the mandrel to be used for the electroforming process. The glass is then metalized. A photoresist mask is formed on the metalized glass and a dielectric is deposited onto the pillars.

Re-usable mandrel for fabrication of ink-jet orifice plates

A plate has a rectangular plate body with a plurality of nozzle arrays. The plate also has first and second end zones in between the plurality of nozzle arrays and opposing ends of the plate body, respectively. There is a break tab in at least one of the first and second end zones. In between the first and second end zones is a middle zone. A plating material encapsulates the plate body in the middle zone.

Orifice plate with break tabs and method of manufacturing

An orifice plate of a fluid ejection device comprises a rectangular plate body having an edge and a plurality of nozzle arrays, wherein the edge has a pair of recesses therealong, and a break tab in between the pair of recesses along the edge.
