Abstract: There are provided a method and an apparatus for manufacturing a metal nanopowder having a uniform particle size distribution by uniformly applying current to a center portion of the metal wire and a surface portion thereof. The method includes increasing a surface roughness of a metal wire; supplying the metal wire having the increased surface roughness to an electrode in a reaction chamber; and wire-exploding the metal wire by supplying electrical energy to the electrode.

Abstract: Disclosed herein is a method for surface treating metal nano particles, including: surface treating metal nano particles with an alkanol amine containing solution.

Abstract: Disclosed herein are a cleaning apparatus of magnetic nanoparticles and a cleaning method of magnetic nanoparticles using the same. The cleaning apparatus of magnetic nanoparticles includes: a cleaning bath into which a solvent and magnetic nanoparticles are fed; a magnet member that is formed at a lower portion of the cleaning bath to separate the magnetic nanoparticles; and a discharge means that discharges the solvent from which the magnetic nanoparticles are separated.

Abstract: The subject invention is directed to a mixed cell composition to generate a therapeutic protein at a target site by providing a first population of mammalian cells transfected or transduced with a gene that is sought to be expressed, and a second population of mammalian cells that have not been transfected or transduced with the gene, wherein endogenously existing forms of the second population of mammalian cells are decreased at the target site, and wherein generation of the therapeutic protein by the first population of mammalian cells at the target site stimulates the second population cells to induce a therapeutic effect.

Abstract: An organic light emitting display and a method of fabricating the same are disclosed. The organic light emitting display may include a transistor on a substrate, a lower electrode on the substrate, the lower electrode being electrically connected to the transistor, an organic light emitting layer on the lower electrode, an upper electrode on the organic light emitting layer, and a buffer layer formed on the upper electrode to modify a predetermined thickness of the upper electrode to be a non-conductive material.

Abstract: The present application discloses a method of preventing degeneration of nerve, which includes: a) generating a recombinant viral or plasmid vector comprising a DNA sequence encoding a member of a transforming growth factor superfamily or neurotrophic factor proteins operatively linked to a promoter; b) transfecting in vitro a population of cultured cells with the recombinant vector, resulting in a population of the cultured cells; and c) transplanting the transfected cells to an area near an injured nerve, such that expression of the DNA sequence within the area near the injured nerve causes prevention of degeneration of the nerve.
