Abstract:
A method for providing 11C-labeled cyanides from 11C labeled oxides in a target gas stream retrieved from an irradiated high pressure gaseous target containing O2, wherein 11C labeled oxides are reduced with H2 in the presence of a nickel catalyst under a pressure and a temperature sufficient to form a product stream comprising at least about 95% 11CH4, the 11CH4 is then combined with an excess of NH3 in a carrier/reaction stream flowing at an accelerated velocity and the combined 11CH4 carrier/reaction stream is then contacted with a platinum (Pt) catalyst particulate supported on a substantially-chemically-nonreactive heat-stable support at a temperature of at least about 900° C., whereby a product stream comprising at least about 60% H 11CN is provided in less than 10 minutes from retrieval of the 11C labeled oxide.
Abstract:
This invention relates to a method of producing aromatics and olefins from oils derived from coal or wood, including partially saturating and cracking the oils derived from coal or wood in a hydrogenation and reaction area, separating them depending on the number of carbons, recirculating heavy oils having 11 or more carbons to the hydrogenation and reaction area, feeding oils suitable for producing BTX to an aromatic separation process and a transalkylation process to recover aromatics, and feeding hydrocarbonaceous components having 5 or less carbons to a light separation process, thus obtaining olefins.
Abstract:
A nonvolatile memory device includes multiple variable resistive elements formed on a substrate; multiple bit lines formed on the variable resistive elements, extended in a first direction, and separated from each other by a first pitch; multiple circuit word lines formed on the multiple bit lines, extended in a second direction, and separated from each other by a second pitch; and multiple circuit word lines formed on the multiple bit lines, extended in the first direction, and separated from each other by a third pitch, wherein the third pitch of the multiple circuit word lines is larger than the first pitch of the multiple bit lines.
Abstract:
The present invention relates to a method of producing aromatic products (benzene/toluene/xylene) and olefin products from petroleum fractions obtained by fluid catalytic cracking, and, more particularly, to a method of producing products comprising high-concentration aromatic products and high value-added light olefin products from light cycle oil obtained by fluid catalytic cracking.
Abstract:
A toilet plunger is used to unclog a drain of a toilet by removing impurities. The toilet plunger includes a gas container, with an opening thereof closed by a closing plate. A body has defined therein a passage extending in the lengthwise direction to allow gas to pass through and a gas container-receiving portion. A puncture pin is disposed in the central portion of the gas container-receiving portion. A cover has an inner space for receiving a portion of the gas container opposite the opening. The cover is screw-coupled to the upper portion of the body, such that the container is moved toward the puncture pin according to a screw motion. An insert is connected to the lower end of the body to guide the discharged gas along the passage toward the drain. A portion of the insert, which is intermediate in length, is bent in one direction.
Abstract:
A wheel house structure for a vehicle, in which a wheel house is assembled with a rear floor assembly. The wheel house of the wheel house structure includes a front wheel house having a first convex portion at one end thereof, and a rear wheel house having a second convex portion at one end thereof, wherein the first and second convex portions are coupled to be overlapped each other to form a beam between the front wheel house and the second wheel house inward the wheel house.
Abstract:
Disclosed herein is a wheel house structure for a vehicle, in which a wheel house is assembled with a rear floor assembly. The wheel house of the wheel house structure includes a front wheel house having a first convex portion at one end thereof, and a rear wheel house having a second convex portion at one end thereof, wherein the first and second convex portions are coupled to be overlapped each other to form a step between the front wheel house and the second wheel house inward the wheel house.
Abstract:
Disclosed is a portable terminal including a case having an opening that faces towards a user operating the terminal and a flange protruding towards the opening, a lower window having a partial surface that is attached to a lower surface of the flange, an upper window attached to the lower window to be exposed through the opening, and a liquid crystal panel placed under the lower window. The stress concentrated on and the likelihood of breakage of the flange structure of the portable terminal in which the case is connected with the window is thereby minimized.
Abstract:
Radiotracer vorozole compounds for in vivo and in vitro assaying, studying and imaging cytochrome P450 aromatase enzymes in humans, animals, and tissues and methods for making and using the same are provided. [N-radio-methyl] vorozole substantially separated from an N-3 radio-methyl isomer of vorozole is provided. Separation is accomplished through use of chromatography resins providing multiple mechanisms of selectivity.
Abstract:
The present invention relates to a method for manufacturing aromatic products (benzene/toluene/xylene) and olefinic products from an aromatic-compound-containing oil fraction, whereby it is possible to substitute naphtha as a feedstock for aromatic production and so make stable supply and demand, and it is possible to substantially increase the yield of high-added-value olefinic and high-added-value aromatic components, by providing a method for manufacturing olefinic and aromatic products from light cycle oil comprising a hydrogen-processing reaction step, a catalytic cracking step, an separation step and a transalkylation step, and optionally also comprising a recirculation step.
