    摘要： A process for the preparation of a catalyst useful for the vapor phase production of ethylene oxide from ethylene and oxygen comprising providing a catalyst precursor comprising an inert support having a catalytically effective amount of a silver containing compound, a promoting amount of an alkali metal containing compound, and a promoting amount of a transition metal containing compound disposed thereon; calcining the catalyst precursor to convert the silver in the silver containing compound to metallic silver by heating the catalyst precursor to form a catalyst; and curing the catalyst in an inert gas atmosphere at temperatures of about 250° C. to about 600° C. for a period of about 1 hour to 200 hours.

    摘要： A device is disclosed that utilizes color or polarization to generate two separate images of the same object taken from the two perspectives that correspond to the left and right eyes of an observer. The two separate images are captured through a single camera objective (e.g., a single shutter camera), resulting in a single image with 3D information encoded in the color or polarization. Advantageously, the images are captured simultaneously, permitting obtaining stereoscopic images of both static and moving subjects, allowing 3D video capture. The device can be an attachment to a conventional, single shutter, image capturing device, such as a camera, a smart phone with a camera feature, computer with a camera feature, and so on.

    摘要： A method for producing a catalyst effective in the oxidative conversion of ethylene to ethylene oxide, the method comprising subjecting a refractory carrier impregnated with a liquid silver-containing solution to a calcination process, wherein the calcination process comprises a solvent removal step in which the silver-impregnated carrier is heated to a base temperature (Tbase) of at least 80° C. and up to about 200° C. to produce a dry carrier impregnated with ionic silver, followed by a silver reduction step in which the dry carrier is gradually heated above the base temperature to a maximum temperature (Tmax) of at least 350° C. and up to about 500° C. and then gradually cooled to the base temperature, wherein the method is conducted such that (Tbase−Tmax)×HW is at least 2000 min.° C. wherein HW is a full width at half maximum of a temperature versus time curve delineated by the silver reduction step.
