摘要:
Disclosed is a carbon nanoball for deodorization composed of a circular hollow core, and a porous carbon shell to which at least one deodorizing material selected from the group consisting of transition metal, oxidized transition metal and alkali metal salt is adhered. The porous carbon shell of the carbon nanoball for deodorization has multi layers more than 2 layers having different pore sizes, and a pore formed in an outer layer has a larger average diameter than a pore formed in an inner layer. This multi-layered carbon nanoball for deodorization may absorb various kinds of stink-generating materials together with good deodorizing capability. Thus, the multi-layered carbon nanoball may give excellent deodorizing effects by capturing and dissolving stinky substances when it used as a deodorant for various stinky daily necessaries or in houses, offices, industrial facilities and other various stink-causing circumstances.
摘要:
Disclosed are mesoporous silica particles and a preparation method thereof, particularly, a method of preparing mesoporous silica particles, including mixing a silica precursor, an alkylamine-based surfactant, and a phosphoric acid-based cosurfactant, thus preparing a mixture solution (a mother liquor); adding or not adding the mixture solution with an acid solution, and conducting stirring, thus providing mesoporous silica particles; and thermally treating the mesoporous silica particles. These mesoporous silica particles are prepared using a phosphoric acid-based cosurfactant for stabilizing the surface of the particles to prevent the aggregation thereof, thereby uniformly distributing the particles. Through a hydrothermal reaction, the mesoporous silica particles have various pore sizes, a large surface area, and a high pore volume, and thus are widely used in catalysts, adsorbents, low dielectrics, and separation and purification processes, and are useful as templates for the preparation of novel porous materials, including porous carbon.

An organic light emitting diode (OLED) display device having a pixel area and a pad area. The pad area includes a silicon layer pattern arranged on the substrate, an insulating layer arranged on the silicon layer pattern, an interconnection layer arranged on the insulating layer, and a protective layer surrounding an edge of the interconnection layer and having an opening exposing the interconnection layer. Since a surface area of the interconnection layer is increased due to a roughness of the underlying polycrystalline silicon layer pattern in the pad area, resulting in increased contact area and reduced contact resistance between parts configured to operate a flat panel display device and the interconnection layer is increased.

摘要:
In an organic light emitting display, a conductive layer is formed on the bottom surface of a substrate, and the conductive layer is used as a wiring line for supplying a power source, and as the electrode of a capacitor. Therefore, it is possible to easily secure the aperture ratio of a pixel, to easily solve the problem of IR drops by controlling the area or thickness of the conductive layer, and to easily secure the electrostatic capacity of the capacitor. In particular, in the case of a front surface light emitting structure, since a capacitor of a metal/insulating layer/metal (MIM) structure may be formed in a light emitting region, enough aperture ratio and electrostatic capacity may be secured. Therefore, a high resolution organic light emitting display may be easily realized, and enough aperture ratio and electrostatic capacity are secured so as to realize high picture quality.
