摘要:
Disclosed herein is a light-responsive photocatalyst composition, which is a composite oxide semiconductor containing tungsten, and which can efficiently absorb visible light emitted from the sun and light emitted from interior lamps, such as fluorescent lamps, etc., and a method of preparing the light-responsive photocatalyst composition. The visible light-responsive photocatalyst composition can decompose volatile organic compounds or harmful organic matter causing sick house syndrome, even indoors, because it can be activated by visible light outdoors and can respond to light emitted from interior lamps, such as fluorescent lamps, etc.

An approach is provided for search services. User-defined search input is received by at least one processor. At least a portion of the user-defined search input is determined, via the at least one processor, as corresponding to at least one functional keyword associated with a type of object to be searched. Classification information is generated to facilitate identification of the at least one functional keyword among at least one other portion of the user-defined search input. Search information is generated about at least one object relating to at least some of the user-defined search input based on at least some of the classification information.

The present invention relates to a method for preparation of organofluoro compounds containing radioactive isotope fluorine-18. More particularly, the present invention relates to a method for preparation of primary or secondary organofluoro compound by reacting fluorine salt containing radioactive isotope fluorine-18 with primary or secondary alkyl halide or primary or secondary alkyl sulfonate in the presence of alcohol of Chemical Formula 1 as a solvent to obtain high yield of organofluoro compound. Synthesis reaction according to the present invention may be carried out under mild condition to give high yield of the organofluoro compounds and the reaction time is decreased, and thereby is suitable for the mass production of the organofluoro compounds.

A method and a device for managing resources of a base station in a wireless communication system is provided. The method comprises: calculating an average resource use of serving resources, which are used as downlinks from a serving base station to a plurality of communication terminals; selecting one of the communication terminals, which has a maximum interference from a neighbor base station, if the calculated average resource use exceeds a preset threshold; and making a reservation for at least one of neighbor resources used as downlinks from the neighbor base station, the at least one neighbor resource corresponding to the serving resource for the selected communication terminal, so that the neighbor base station may decrease transmission power in the at least one neighbor resource.
摘要:
A process and apparatus for separating an olefin from mixed gases containing light olefins is provided. The process includes adsorbing the olefin of an olefin-containing mixed gas in an adsorption column packed with an adsorbent selectively adsorbing the olefin; discharging gases other than the olefin through the outlet of the adsorption column; desorbing the adsorbed olefin by displacement using a desorbent, and separating the olefin from the desorbent, thereby producing a high-purity olefin. The apparatus includes adsorption columns packed with an adsorbent selectively adsorbing an olefin, and at least two distillation columns for separating an olefin/desorbent mixture and an olefin poor stream/desorbent into their components. If the olefin concentration of the off-gas from an olefin rinse step is higher than that of a raw material gas, recovering the olefin from the off-gas is carried out before or after the adsorption step.
摘要:
[Structure] An olfactory display 10 includes a housing 12 having an emitting port 22, and presents a fragrance within a range bounded in terms of time and space. Within the housing 12, a fragrance chamber 14 having an air inlet 26 and a fragrance outlet 24 which is communicated with the emitting port 22 is formed, and in the fragrance chamber 14, a solid-like fragrance source 20 is accommodated. Furthermore, in the fragrance chamber 14, there is provided with a airflow source 16 comprising a diaphragm 34 having a piezoelectric device 32. In presenting a fragrance, an air is sent into the fragrance chamber 14 from the air inlet 26 by the airflow source 16, and accordingly, the air within the fragrance chamber 14, which including a gas-like fragrance component volatilized from the fragrance source 20 is emitted from the emitting port 22 passing through the fragrance outlet 24.
