Abstract: The present invention relates to an electrolyte containing a polydopamine and a lithium-sulfur battery including the same and, more particularly, to a technique in which polydopamine contained in an electrolyte adsorbs a lithium polysulfide eluted from a positive electrode of a lithium-sulfur battery. When using an electrolyte, according to the present invention, to which polydopamine particles are added, the polydopamine particles dispersed in the electrolyte act to adsorb lithium polysulfide eluted from a positive electrode during the charging and discharging, and thus can suppress the diffusion thereof, i.e., suppress a shuttle reaction, thereby improving the capacity and lifetime characteristics of the lithium-sulfur battery.

Abstract: The present invention relates to a separator for a lithium-sulfur battery having a composite coating layer including polydopamine, and a method for preparing the same, and in particular, to a lithium-sulfur battery suppressing lithium polysulfide elution by using a composite coating layer including polydopamine and a conductive material on one surface of a separator. In the lithium-sulfur battery according to the present invention, a porous structure of polydopamine adsorbs lithium polysulfide eluted from a positive electrode preventing elution and diffusion, and by providing additional electric conductivity, a reaction site of a positive electrode active material is provided, and therefore, battery capacity and life time properties are enhanced.

Abstract: The present invention relates to a curable composition and a use thereof and, more particularly, to a curable composition and a use thereof, the curable composition comprising: (a) a compound capable of being denatured to a quinone-based compound by oxygen; (b) an amine-based polymeric compound; and (c) an oxygen clathrate structure. The curable composition is rapidly cured and can be cured not only at an interface of a conventional film but also to the inside of the film, such that the curable composition has uniform physical properties throughout the entire film and excellent physical properties compared to a curing film obtained by curing at an existing interface.

Abstract: The present invention relates to a heart targeting agent comprising tannic acid, in which the agent aids a heart disease therapeutic drug to be delivered to the heart and bind to the cardiac myocardium by inducing tannylation of the drug so as to make heart targeting and accumulation of the drug possible. Unlike the conventional invasive method used for the traditional drugs to be able to target the heart, the agent of the present invention can help a drug to target the heart with high efficiency just via non-invasive intravenous administration.

Abstract: The present invention provides facile and accurate molecular diagnosis of disease-specific genes capable of the naked eye detection through amplifying the target genes to selectively block the fluid path in a microfluidic device. Specifically, the present invention includes an isothermal amplification of target genes through a rolling circle amplification, a microfluidic device for detecting pathogen genes, and a detection method using the same. Therefore, the present invention can conveniently detect a single target gene, such as a single pathogen, or at the same time, several target genes, such as several pathogens, without complicated mechanical equipment.
