  • Patent number: 11944958
    Abstract: Disclosed herein are a catalyst for hydrocracking reaction of high molecular weight components in bio-oil, a method for preparing the same and a method for bio-oil upgrading using the same. The catalyst includes a zeolite carrier; and at least one metal selected from the group consisting of nickel (Ni), ruthenium (Ru) and cerium (Ce) supported on the carrier. The catalyst promotes the hydrocracking of high molecular weight compounds contained in the bio-oil, but also inhibits the polymerization reaction of the decomposed product, thereby more effectively enhancing the hydrocracking reaction of the bio-oil.

  • Patent number: 9118000
    Abstract: Provided are a method of manufacturing a flexible piezoelectric energy harvesting device using a piezoelectric composite, and a flexible piezoelectric energy harvesting device manufactured by the same. The method of manufacturing the flexible piezoelectric energy harvesting device includes: forming a first electrode layer on a first flexible substrate; spin-coating a piezoelectric composite layer on the first electrode layer, wherein the piezoelectric composite layer is produced by mixing piezoelectric powder with polymer; performing heat treatment on the piezoelectric composite layer to harden the piezoelectric composite layer; and bonding a second flexible substrate with a second electrode layer on the hardened piezoelectric composite layer. Therefore, it is possible to simplify a manufacturing process and manufacture a high-performance flexible piezoelectric energy harvesting device having various sizes and patterns.

  • Patent number: 8828845
    Abstract: Provided is a method of fabricating an oxide thin film device using laser lift-off and an oxide thin film device fabricated by the same. The method includes: forming an oxide thin film on a growth substrate; bonding a temporary substrate on the oxide thin film; irradiating laser onto the growth substrate to separate the oxide thin film on which the temporary substrate has been bonded from the growth substrate; bonding a device substrate on the oxide thin film on which the temporary substrate has been bonded; and forming an upper electrode film on the oxide thin film. Therefore, it is possible to overcome problems caused by a defective layer by transferring an oxide thin film transferred on a polymer-based temporary substrate onto a device substrate, without using an interface on which a defective layer formed due to oxygen diffusion upon laser lift-off is formed.

  • Patent number: 8749023
    Abstract: Disclosed are a ReRAM, which is a non-volatile memory device, and a production method therefor. A resistance-variable layer, which varies the resistance in accordance with an applied pulse, has a multilayered structure comprising 3 oxide films. Each oxide film consists of an oxide film of the same type as the neighbouring oxide film(s), but the oxygen ratios in the compositions of neighbouring oxide films differ from each other.

  • Publication number: 20080200003
    Abstract: The invention relates to a method for forming a multi-layered binary oxide film for ReRAM. The method includes forming a lower electrode layer on a substrate; forming a metal layer on the lower electrode layer in a vacuum atmosphere; oxidizing the metal layer into a binary oxide film in a vacuum atmosphere; repeating the steps of forming and oxidizing the metal layer to form a desired thickness of the multi-layered binary oxide film; and forming an upper electrode layer on the multi-layered film. The method allows a nonvolatile memory device more efficient than the conventional perovskite structure in a simple process without concerns for surface contamination since the metal layer is formed and oxidized in a vacuum atmosphere.
