Abstract: The present invention relates to a method for fabricating microparticles by using a degassed gas-permeable micro-mold and discontinuous dewetting. The method for fabricating microparticles according to the present invention comprises the steps of: depressurizing and degassing a porous micro-mold including a plurality of micro-wells concavely recessed in a predetermined shape and size from one surface thereof (S100); loading a microparticle precursor solution on which the micro-wells are formed, and covering the microparticle precursor solution with a cover substrate (S200); moving the to cover substrate to the side (S300); and curing the microparticle precursor solution filled in the micro-wells, thereby synthesizing microparticles (S400).

Abstract: A method for preparing a pitch for carbon fibers and a pitch for carbon fibers prepared by the same are disclosed. The method includes introducing a peroxide compound and ozone into a petroleum-process residual oil, followed by heat treatment for reaction. By the method, the pitch for carbon fibers, which exhibits excellent oxidative stabilization and oxidative incompatibility while having a high softening point and high strength, can be obtained at high yield at a relatively low temperature.

Abstract: A dome switch integrated touch window for a mobile terminal includes a lower substrate, a dome switch, a spacer sheet, and an upper substrate. A dome switch is disposed on a lower substrate to correspond to a contact terminal. The dome switch extends through a spacer sheet and an upper substrate disposed on the spacer sheet. The dome switch is covered by a design film. The dome switch includes an operation member having a resilient base disposed over the contact terminal and a resilient protrusion projecting from the resilient base, and a dome disposed between the operation member and the lower substrate. The operation member may have an upwardly concaved dome-shaped groove to receive the dome.
