Abstract:
In the present invention, a copper electrode having a nanohole structure is prepared by using a polymer substrate in the form of nanopillars in order to avoid fatigue fracture that causes degradation of electrical and mechanical properties of a flexible electrode during repetitive bending of a typical metal electrode. The nanohole structure may annihilate dislocations to suppress the initiation of fracture and may blunt crack tips to delay the propagation of damage. Therefore, the nanohole electrode exhibits very small changes in electrical resistance during a bending fatigue test.
Abstract:
Disclosed is an entropy-controlled solid solution matrix BCC alloy having strong resistance to high-temperature neutron radiation damage. The entropy-controlled solid solution matrix BCC alloy includes three or more multicomponent main elements selected from the element group consisting of Zr, Al, Nb, Mo, Cr, V, and Ti selected based on a neutron absorption cross-sectional area and a mixing enthalpy. Each of the elements is included in an amount of 5 to 35 at %, and the entropy-controlled solid solution matrix BCC alloy is a BCC-structure solid solution matrix alloy in a medium-entropy to high-entropy state. In this invention, damage caused by neutron radiation is reduced, and entropy is controlled to thus ensure a solid solution matrix BCC structure having a slow diffusion speed, and accordingly, resistance to void swelling due to radioactive rays is high.

Abstract:
Disclosed is a method for preventing, improving and/or treating cornea damage or a corneal disease, including administering an effective amount of an extract of a persimmon tree for preventing, improving or treating cornea damage to a subject in need thereof. The extract may be a persimmon leaf extract and the extract is effective in suppressing inflammation of the cornea and protecting corneal cells.
Abstract:
The present invention relates to a drug carrier having L-DNA nanocage structure prepared by using L-DNA, the mirror form of natural DNA, as a backbone. The drug carrier of the present invention has very superior cellular uptake efficiency and serum stability, so that it can be applied to deliver various drugs into cells usefully.
Abstract:
Disclosed herein are a transformed Synechococcus elongatus strain having improved capability of producing acetone and a method for producing acetone and a method for removing carbon dioxide using the same. In an aspect, the transformed Synechococcus elongatus strain of the present disclosure can produce acetone with high selectivity using carbon dioxide as a carbon source. The present disclosure is economical because the Synechococcus elongatus strain can economically produce high value-added acetone using carbon dioxide existing in the atmosphere as a carbon source without requiring an additional catalytic reaction. Also, the present disclosure is environment-friendly because carbon dioxide in the atmosphere can be removed or reduced using the microorganism.
Abstract:
The present invention relates to a nanophosphor and a synthesis method thereof, and provides a nanophosphor comprising a first compound of Formula 1, wherein the first compound is fluoride-based one which is co-doped with Ce3+ and Tb3+. NaGd1−p−q−rMrF4:Ce3+p,Tb3+q (1) In the Formula 1, descriptions on the p, q, r and M are overlapped with what was described in the detailed description of the present invention, so their concrete description are omitted. The nanophosphor has good light emission intensity and magnetic property as well as up-conversion and/or down-conversion property able to emit visible light after excitation by infrared and/or ultraviolet rays, so can be applied to a contrast agent and a counterfeit prevention code.
