Abstract: Disclosed is an energy storage device based on metal oxide nanocrystals resealed through lithiation, and a supercapacitor using the same. The energy storage device is fabricated by dispersing transition metal nanoparticles over a carbon-based support with a large specific surface area, and then, dispersing and resealing the nanoparticles over the support using lithium ions with strong reductive ability, so that the resealed metal particles are substantially particles dispersed and resealed over the support as particles having a size of less than 1 nanometer on the scale of atomic units. The supercapacitor is fabricated using the energy storage device. The energy storage device higher capacitance than before resealing of metal oxide. Since the resealed metal particles are those having a size of less than 1 nanometer on the scale of atomic units, interference between particles disappears to exhibit excellent cycle life characteristics of 100% maintained performance in even more than 100,000 cycles.

Abstract: A method of preparing nucleic acid-inorganic hybrid nanoflowers is described, in which a nucleic acid is allowed to react with a solution of a metal ion-containing compound at room temperature, thereby forming a complex between the metal ion and the nitrogen atom of an amide bond or amine group present in the nucleic acid. Organic-inorganic hybrid nanoflower structures thus may be synthesized using nucleic acid in a simple manner under an environmentally friendly condition without any toxic chemical substance. The produced organic-inorganic hybrid nanoflower structures exhibit a high DNA encapsulation yield, nuclease resistance, and significantly increased peroxidase activity. These nanoflower structures may be widely used as gene therapy carriers and in biosensing technology.

Abstract: The present specification suggests a method for establishing a terminal-centric group cell on the basis of measurement signal variation for cooperative transmission and handover in a mobile communication system. Specifically, a base station receives transmissions of parameters from a terminal, configures a terminal surrounding cell information table, and configures a cooperative cell cluster configuration table using the terminal surrounding cell information table as the terminal moves. The base station performs cooperative transmission and handover using the cooperative cell cluster configuration table. The terminal sends parameters to the base station periodically or when a certain condition is met, and the base station updates the terminal surrounding cell information table and the cooperative cell cluster configuration table using the parameters sent from the terminal to thereby use the same for mobility management.
