Abstract: A cathode heater assembly for use in a vacuum electronic device comprises a refractive cup having a bottom portion and side walls forming a container; a cathode secured in the container of the refractive cup; and a heater wire coupled to the refractive cup. The cathode heater assembly may be manufactured by providing a refractive cup having a bottom portion and side walls forming a container; inserting a cathode pellet in the container of the refractive cup; impregnating the cathode pellet with electron emissive materials while the cathode pellet is in the container of the refractive cup; and attaching a heater wire to the refractive cup.

Abstract: This invention generally relates to cationic oil-in-water emulsions that contain high concentrations of cationic lipids and have a defined oil:lipid ratio. The cationic lipid can interact with the negatively charged molecule thereby anchoring the molecule to the emulsion particles. The cationic emulsions described herein are useful for delivering negatively charged molecules, such as nucleic acid molecules to cells, and for formulating nucleic acid-based vaccines.

Abstract: Ink compositions for forming active layers in an organic light-emitting diode are provided. Also provided are methods of forming active layers of an OLED using the ink compositions. The ink compositions comprise a solvent system in which a substantial majority of the solvent is comprised of one or more ester compounds.

Abstract: A cosmetic container that includes a lid assembly and a base assembly, the base assembly configured to hold a cosmetic product. The lid assembly and the base assembly are pivotably coupled to one another. The lid assembly may be releaseably secured to the base assembly through a rotatable handle and release mechanism. Rotation of the handle may actuate the release mechanism to move a clasp between a locked and an unlocked configuration to lock and unlock the lid assembly relative to the base assembly.

Abstract: The present teachings relate to various embodiments of an ink composition, which once printed and cured forms an organic thin film on a substrate such as, but not limited by, an OLED device substrate. Various embodiments of the ink can be printed using an industrial inkjet printing system that can be housed in a gas enclosure, which gas enclosure defines an interior that has a controlled environment maintained as an inert and substantially low-particle process environment. Patterned printing of an organic thin film on a substrate, for example, but not limited by, an OLED device substrate, in such a controlled environment can ensure a high-volume, high yield process for a variety of OLED devices.
