    Abstract: Provided is a method for manufacturing metal nanoparticles having a core-shell structure with good oxidation stability, wherein the method comprises the steps of: heating and agitating a core metal precursor solution; mixing a shell metal precursor solution with the heated and agitated core metal precursor solution, and heating and agitating the mixed metal precursor solution; and irradiating the heated and agitated metal precursor solution with radioactive rays. Thus, since yield can be maximized through a simple and environmentally friendly process that does not use a chemical reducing agent, there is no need for a process for removing an added reducing agent, and since a post-heat-treatment of particles is not performed, the manufacturing process is rendered simple and highly economical.

    Abstract: An electron beam irradiator capable of performing electron beam irradiation in a wide area at a high current density with a field emitter tip. The electron beam irradiator comprises: a vacuum chamber having a beam irradiation window formed longitudinally in an outer periphery of the vacuum chamber; a cathode placed centrally and longitudinally inside the vacuum chamber, and having a field emitter tip formed on the cathode, corresponding to the beam irradiation window; and a high voltage supply placed at one end of the vacuum chamber, and adapted to apply high voltage toward the cathode. The electron beam irradiation can be made in a wide area without using an electromagnet as well as in a high current density without using a heater such as a filament or an additional power supply, thereby to ensure a simplified structure as well as a reduced size.
