Disclosed are a silica sol composition including silica, an anionic dispersant, a cationic dispersant, an epoxy silane coupling agent, and an organic solvent, and a method for preparing the same. In the silica sol composition, a uniform surface modification of silica particles may be achieved by using an anionic dispersant and a cationic dispersant, and it is possible to effectively enhance the compatibility between a silica filler whose surface is modified with an epoxy group and a resin which is an underfill composition.

The present invention relates to a cathode for a metal-air battery, a method for manufacturing the same, and a metal-air battery including the same. The cathode comprises a needle-shaped core including two or more species of metals selected from the group consisting of nickel, cobalt, manganese, zinc, iron, copper, and chrome, or a cobalt oxide; and a flake-shaped shell including an oxide containing two or more species of metals selected from the group consisting of nickel, cobalt, manganese, zinc, iron, copper, and chrome or a cobalt oxide. As such, the core-shell structure may lead to a reduction in the charge voltage of the metal-air battery as well as the taking of the good capacity characteristics of the transition metal oxide. Further, according to the present invention, the cathode for a metal-air battery may be produced without adding carbon or binder.

This invention relates to a cathode for a lithium-air battery, a method of manufacturing the same and a lithium-air battery including the same. The method of manufacturing the cathode for a lithium-air battery includes 1) stirring a cobalt salt, triethanolamine and distilled water, thus preparing a cobalt solution, 2) electroplating the cobalt solution on a porous support, thus preparing a cobalt plated porous support, 3) reacting the cobalt plated porous support with a mixture solution including oxalic acid, water and ethanol, thus forming cobalt oxalate on the porous support, and 4) thermally treating the cobalt oxalate.

The present invention provides a method of separating ethylene or ethane from a mixed gas containing ethylene and ethane using hydroquinone. According to the present invention, hydroquinone selectively forms a clathrate with ethylene, and thus it is possible to separate ethylene with high yield and purity through a single process.

A disposable life-saving garment for use in the event of fire, comprises a body-protecting portion and a head-protecting portion. The body-protecting portion is configured with a lining formed to enclose the body of a wearer and a cover covering the liner, the cover being made of a sealed material that can block the passage of air. A closed air passage is formed between the liner and cover. A compressed air tank is installed in a pocket of the cover and is connected to the air passage through a check valve. An intake hose supplies compressed air from the air passage of the body-protecting portion to the head-protecting portion. The head-protecting portion has a heat-resistant transparent window and a one-way outlet unit. The body-protecting portion and the head-protecting portion are made of a nonflammable material or a fire retardant material.
