Abstract: The present disclosure is related to a coating method of a long-chain entangled PDMS (LEP) gel in which self-replenishment of a lubricating layer is sustainable. More specifically, it is possible to achieve excellent slippery properties, anti-fouling performance, and anti-icing performance for a long period of time due to sustainable self-replenishment performance of a surface coated with LEP gel, by forming LEP gel impregnated with a low-viscosity silicone oil as a lubricant into the surface of long-chain entangled PDMS (LEP), in which long-chain free polymers are entangled in PDMS networks.

Abstract: A method and system for generating a target map for training a neural network and obtaining a sound source map regardless of the maximum number of sound sources, having a short computation time for inference, high spatial resolution and high sound source accuracy. The method includes generating grids each having a spacing within a given range at positions where sound sources are present in order to form a sound source map, calculating a result value for each of coordinates of the grids so that the result value is a local maximum at the position of a sound source and the result value decreases depending on the distance from the sound source, arranging the result values at positions on matrices corresponding to the respective coordinates of the grids, and generating a target map having an image form by using the result values arranged in on the matrices.

Abstract: Provided are a new ultrathin film silicon shadow mask which is flexible, is reusable, and can be precisely aligned and manipulated through transfer printing, and a lithography method using the same. A thin thickness of a silicon shadow mask may intrinsically form a pattern having an enhanced resolution in a plane and a non-planar surface. Further, the silicon shadow mask may be formed on a substrate by metal deposition in addition to etching in a multi-layer configuration by a transfer printing technology based alignment method. Through such a method, a material in which patterning is impossible may be patterned through photolithography.
