Abstract: A method of manufacturing a stacked structure includes forming a first metal buffer layer including crystal grains on a base substrate, forming a second metal buffer material layer on the first metal buffer layer, and crystallizing the second metal buffer material layer to form a second metal buffer layer, wherein the second metal buffer material layer includes crystal grains, and a density of the crystal grains of the second metal buffer material layer is lower than a density of the crystal grains of the first metal buffer layer.

Abstract: A self-healing alloy contains 5 to 11% by weight of molybdenum (Mo), iron (Fe) as a remainder, and unavoidable impurities. A method for manufacturing the self-healing alloy includes heat treating the alloy or preparing an alloy raw material powder and sintering, homogenizing, and cooling the alloy raw material powder.

Abstract: The present invention relates to a method for preparing a radioactive film for local radioactive treatment. More particularly, the present invention relates to a method for preparing a radioactive film comprising the steps of; dissolving 0.1˜14.5 weight % of a stable nuclide and 13˜32.5 weight % of a film-forming base for the total amount of a solvent in the solvent; applying a stable nuclide solution on a release paper by a coater and drying; and irradiating a stable nuclide film with neutrons in a nuclear reactor. A method for preparing a radioactive film according to the present invention provides a radioactive film having a uniform distribution of radionuclides and an even thickness. Therefore, the therapeutic efficacy of the radioactive film for selective treatment of a lesion may be maximized by attaching the radioactive film on a patient's skin or a mucous membrane and by direct radioactive radiation.
