Abstract: The present invention relates to a foam-shaped graphene structure and, more particularly, to a method for producing a foam-shaped graphene structure by boiling, and to a foam-shaped graphene structure using same. Provided is a method for producing a foam-shaped graphene structure by boiling, which includes the steps of: preparing a base substrate (S1); placing the base substrate in a reduced graphene oxide (RGO) colloid solution (S2); applying a heat flux to the base substrate using an exothermic body so as to cause boiling (S3); and generating the foam-shaped graphene structure on the base substrate as bubbles generated by the boiling become overlapped (S4).

Abstract: A sodium-nanoliquid reactivity experiment apparatus includes: a storage tank that stores liquid sodium; a mixing tank that is connected to the storage tank through a first transport line to receive supply of the liquid sodium and that injects nanoparticles to mix the nanoparticles with the liquid sodium; and a reactor that is connected to the mixing tank through a second transport line to receive supply of a sodium-nanoparticle mixture and that injects water to react the water with the sodium-nanoparticle mixture.

Abstract: Provided is an apparatus for anodizing an internal surface of a tube including an electrolyte container storing an electrolyte solution, a first solution conduit connected with the electrolyte container to receive the electrolyte solution, a first jig configured to fix one end of a targeted tube to a downstream end of the first solution conduit, a second solution conduit in which the other end of the targeted tube is connected to an upstream end to discharge the electrolyte solution flowing into the targeted tube, a second jig configured to fix the other end of the targeted tube to an upstream end of the second solution conduit, and a cathode rod inserted from the second jig and extended to the first jig through the inner portion of the targeted tube, in which, while the electrolyte solution passes through the inner portion of the targeted tube, a cathode is applied to the cathode rod and an anode is applied to the targeted tube to perform an anodizing process.
