Abstract: Systems and methods for high throughput fabrication and analysis of an array of coated materials. The systems include a movable substrate having a plurality of predefined regions, where a plurality of materials are provided for coating the substrate. A delivery mechanism associated with the plurality of materials delivers a continuously varying mixture of the plurality of materials onto the surface of the substrate. The methods include delivering a continuously varying mixture of a plurality of materials onto the surface of a movable substrate having a plurality of predefined regions to form a predefined coating on each of the regions.

Abstract: An electron emitter includes a coating layer of a mixture of carbon nanotubes and alkali-earth metal oxides on an electrically conducting structure. The preferred carbon nanotubes are those having a diameter less than about 200 nm. A substantial portion of electron emission is liberated from the carbon nanotubes, thus lessening the requirement on the alkali-earth oxides. Such an electron emitter is advantageously used in gas discharge devices to increase the energy efficiency thereof.

Abstract: A method includes providing a substrate and depositing components of a test contaminant library onto regions of the substrate to form at least two test contaminant members of the library. In another method, a chemical cleaning solution is selected by combinatorial high throughput screening. In the method, components of a test contaminant library are deposited onto regions of a substrate to form at least two test contaminant members of the library. The substrate is cleaned with a cleaning solution and cleanliness of the substrate evaluated to select a cleaning solution for at least one of the contaminant members. In a final embodiment, the invention is a combinatorial high throughput screening array plate, comprising (A) a substrate and (B) a test contaminant library deposited on the substrate.
