Technologies are described for methods for fabricating a film component. The methods may comprise sputtering a first film onto a substrate. The first film may include a semiconductor compound material. The semiconductor compound material may include a semi-metal material and one or more alkali material. The methods may further comprise evaporating a second film onto the first film. The second film may include the one or more alkali materials. The one or more alkali materials may catalyze crystallization of the semiconductor compound material in the first film substantially throughout the first film to form the film component in the first layer.

Photocathode and method for assembly

A vacuum encapsulated, hermetically sealed cathode capsule for generating an electron beam of secondary electrons, which generally includes a cathode element having a primary emission surface adapted to emit primary electrons, an annular insulating spacer, a diamond window element comprising a diamond material and having a secondary emission surface adapted to emit secondary electrons in response to primary electrons impinging on the diamond window element, a first high-temperature solder weld disposed between the diamond window element and the annular insulating spacer and a second high-temperature solder weld disposed between the annular insulating spacer and the cathode element. The cathode capsule is formed by a high temperature weld process under vacuum such that the first solder weld forms a hermetical seal between the diamond window element and the annular insulating spacer and the second solder weld forms a hermetical seal between the annular spacer and the cathode element whereby a vacuum encapsulated chamber is formed within the capsule.

The cathode capsule is formed by a vacuum cold-weld process such that the first cold-weld ring forms a hermetical seal between the cathode element and the annular insulating spacer and the second cold-weld ring forms a hermetical seal between the annular spacer and the diamond window element whereby a vacuum encapsulated chamber is formed within the capsule.

Chemotactin, diethyl phthalate, is shown to be a chemoattractant secreted by H. pylori. Chemotactin attracts phagocytic cells with a resulting inflammatory episode. Chemotactin and its metabolites may be used for diagnosis and monitoring courses of infection by H. pylori or other chemotactin secreting organisms. In addition, chemotactin may be used in research for studying the inflammatory process, for identifying new drugs for modulating chemoattraction and activation of phagocytic cells, and for inducing an inflammatory response as a therapeutic intervention.
