Abstract: A flexible display device is disclosed. The flexible display device comprises a first body, a second body, a flexible display, a ball module, and rails. The ball module includes a case and a plurality of moving balls. The moving balls are inserted into circulation paths of the case and arranged to be movable along the circulation paths, and some of the moving balls are in contact with sliding grooves of the rails. The case may be fixed to the first body, and the rails may be fixed to the second body. When the second body moves in parallel to a first direction with respect to the first body, the moving balls in contact with the sliding grooves roll and move along the circulation paths, such that slippage and friction generated on the ball module can be reduced, and the second body can move smoothly.

Abstract: The present invention relates to a multi-functional nucleic acid-based anti-cancer drug in which the anti-cancer drug is physically bound to a linear nucleic acid having a thiol group at 5? terminal thereof and then gold nanoparticles and aptamers are chemically bound. The present invention also relates to a method for preparing the anti-cancer drug and to an anti-cancer composition comprising the anti-cancer drug. The multi-functional nucleic acid-based anti-cancer drug according to the present invention uses A10 aptamer to achieve high targeting properties, and uses high-concentration anti-cancer drugs and gold nanoparticles to enable dual therapy of thermal therapy/chemical therapy, and may have less side effects and be more effective in anti-cancer therapy compared to existing anti-cancer drugs.

Abstract: A method of manufacturing a thin-film bonded substrate used for semiconductor devices. The method includes the steps of epitaxially growing an epitaxial growth layer on a first substrate of a bulk crystal, cleaving the first substrate, thereby leaving a crystal thin film on the epitaxial growth layer, the crystal thin film being separated out of the first substrate, and bonding a second substrate to the crystal thin film, the chemical composition of the second substrate being different from the chemical composition of the first substrate. It is possible to preclude a conductive barrier layer of the related art, prevent a reflective layer from malfunctioning due to high-temperature processing, and essentially prevent cracks due to the difference in the coefficients of thermal expansion between heterogeneous materials that are bonded to each other.

Abstract: A thermochromic substrate and a pair-glass with a thermochromic thin film, which increases the efficiency with which solar energy is transmitted and blocked. The thermochromic substrate includes a base substrate, a thermochromic thin film coating the base substrate, and a high-refractivity thin film coating the thermochromic thin film. The high-refractivity thin film shifts the reference wavelength in the infrared range, at which the variance in the transmittance due to the phase transition does not exceed 0, to a shorter wavelength. The efficiency with which solar energy is transmitted and blocked is increased, thereby decreasing the load of cooling and heating a building.
