Abstract: Provided are a method for preparing a polyetherketoneketone and a polyetherketoneketone prepared thereby, wherein, at the time of a polymerization reaction, nitrogen gas is blown into a liquid reaction medium while stirring, thereby quickly removing hydrochloric acid, which is a by-product generated during the reaction, and preventing aggregation of resin particles, thus suppressing the generation of scales.

Abstract: A battery module includes a housing having an internal space, a cell stack disposed in the internal space and including a plurality of battery cells and one or more thermal barrier assemblies, and an adhesive member disposed between the cell stack and the housing, wherein at least a portion of the adhesive member fills a gap between at least one edge of the thermal barrier assembly and the housing, and the at least one edge of the thermal barrier assembly is coupled to the housing by the adhesive member.

Abstract: The present disclosure relates to a battery module including: a battery cell stack in which a plurality of battery cells are stacked; and a pressure drop sheet on one side of the battery cell stack, in which the pressure drop sheet includes: a ventilation layer including ceramic fiber; and a sacrificial layer on at least one face of the ventilation layer, the sacrificial layer is disposed in a direction facing the battery cell stack, and the pressure drop sheet exhibits gas permeability at a critical temperature.

Abstract: Provided are an apparatus and a method for controlling a stored image in an image display device. When a time shift function is selected by a user in the image display device having a storage function, information regarding a recording material for each time with respect to time-shifted contents, and exploration to a desired position is conveniently made. That is, a list of time-shifted contents is generated in cooperation with collectable program information and source (channel) information during broadcast, and information for maintenance and management of time shift. The generated list of the contents is displayed in the form of one of summary, a list, and an EPG. When one of the contents displayed on the EPG is selected by the user referring to the EPG, movement is made to a corresponding position, and a corresponding program is reproduced. Therefore, times consumed for searching for and exploring contents, and movement to a position of the contents can he reduced.

Abstract: A display apparatus and a method of controlling the display apparatus are provided. The display apparatus includes: a display configured to display an image; a voice receiver configured to receive a user's voice; a storage configured to store information about the user's voice; and a controller configured to select a first operation of the display apparatus in response to a user's input, receive a first utterance of the user's voice corresponding to the selected first operation, store information about the received first uttered voice in the storage, receive a second utterance of the user's voice, and perform the corresponding first operation to be performed if the received second utterance of the user's voice matches the received first utterance of the user's voice.

Abstract: The present invention is a method of treating nitrogen oxides using an ozone and catalyst hybrid system, as well as an apparatus, specifically relating to a method of treating nitrogen oxide using an ozone and catalyst hybrid system comprising: 1)removing moisture from the nitrogen oxide polluted air to be treated; 2) contacting the moisture-removed nitrogen oxide polluted air with ozone to oxidize NO in said polluted air to NO2; 3) reacting the residual ozone with a catalyst to generate oxygen radicals and then, reacting the oxygen radicals with the nitrogen oxide polluted air from step 2) to oxidize NO2 in the polluted air to NO3?. The nitrogen oxide treatment method and apparatus according to the present invention can effectively treat harmful nitrogen oxides, such as NO, NO2, using an ozone and catalyst hybrid system at room temperature without requiring a high temperature reaction or an ammonia gas as a reducing agent.
