Abstract: A selector according to an embodiment of the present disclosure includes a first electrode; a second electrode disposed opposite to the first electrode; an ion supply layer disposed between the first electrode and the second electrode to be on the side of the first electrode and doped with a metal, wherein the doped metal diffuses toward the second electrode; a switching layer disposed between the first electrode and the second electrode to be on the side of the second electrode, wherein the doped metal diffuses from the ion supply layer into the switching layer so that metal concentration distribution inside the switching layer is changed to generate metal filaments; and a diffusion control layer inserted between the ion supply layer and the switching layer, wherein the diffusion control layer serves to adjust electrical characteristics related to the generated metal filaments as the amount of the diffusing metal is adjusted in proportion to a thickness of the diffusion control layer.

Abstract: A vehicle door glass assembly capable of regulating a position of a door glass may include a door frame forming a vehicle door; a garnish joined to a periphery of the door frame to finish an outer side face of the door frame; the door glass installed so as to be raised or lowered within the door frame; a glass run assembled to the door frame to support a periphery of the door glass; and a slider installed in an inner side face of the door glass to guide a raising or lowering movement of the door glass, where the garnish is provided with a restraint device configured to prevent the slider from moving in a longitudinal direction of a vehicle.

Abstract: A door glass assembly includes a door frame configured to form a door of a vehicle, a door glass configured to be installed in the door frame to be ascended and descended relative to the door frame, a garnish configured to be engaged with an outer surface of the door frame so that the outer surface of the door frame is finished with the garnish, a slider installed on the door glass and having a front end received in the door frame to guide the door glass, and a position adjusting part provided on an inner surface of the door glass and configured to adjust a gap between an end portion of the door glass and the garnish.

Abstract: A door glass assembly for a vehicle is configured such that a driving motor for raising and lowering a door glass of the vehicle is directly connected to the door glass. The door glass assembly for the vehicle includes the door glass installed to be capable of being raised and lowered in a door of the vehicle and the driving motor for raising or lowering the door glass. The door glass assembly further includes a motion converting means for converting the rotational motion of the driving motor into the linear motion of the door glass between the driving motor and the door glass.

Abstract: A door glass assembly capable of adjusting position includes a door frame configured to form a door of a vehicle, a door glass configured to be installed at the door frame to be ascended and descended, a garnish configured to be engaged with an outer surface of the door frame so that an outer surface of the door frame is finished with the garnish, a slider installed on at an inner circumference of the door glass and having a front end received in the door frame to guide the door glass to be ascended and descended, and a position adjusting part provided at an inner surface of the door glass and configured to adjust a gap between an end portion of the door glass and the garnish by varying a position of the slider.

Abstract: Disclosed is a fuel composition for fuel cells with improved performance. In order to efficiently remove undesirable intermediates of a fuel cell that uses liquid oxygenated hydrocarbons as fuel thereof, polyoxometalate as an oxidation assistant is directly added to the fuel cell. Herein, polyoxometalate includes at least one redox reactive anion caused by dissolution of polyoxometalate in an organic medium containing solution and/or an aqueous solution. The intermediates generated during activating the fuel cell are efficiently oxidized and, additionally, carbon monoxide with the property of catalyst poisoning of electrode catalyst is eliminated, thereby accomplishing improvements in poisoning resistance of the catalyst and, in turn, performance of the fuel cell.
