The present invention relates to an electrode for electrolysis having a coating layer containing a ruthenium oxide, a platinum group oxide, and a manganese oxide. The electrode for electrolysis of the present invention is characterized by exhibiting excellent durability and an improved overvoltage since a tin oxide contained in a coating layer interacts with a ruthenium oxide and a platinum group oxide which are contained together to improve electrical conductivity.

Electrode for electrolysis

The present invention provides an electrode for electrolysis in which a planarized metal substrate having a mesh structure such that the aspect ratio of an individual cross-section of a wire constituting the mesh structure is 120% or greater is used to increase the surface area of a coating layer, thereby increasing adhesion to a membrane and gas trap is reduced to reduce overvoltage.

Provided is an active layer composition of a reduction electrode for brine electrolysis containing a metal precursor mixture containing a ruthenium precursor, a platinum precursor, and a lanthanide metal precursor, and an organic solvent containing an alcohol-based compound and an amine-based compound. Also provided is a reduction electrode containing a metal substrate and an active layer that is a dried and heat treated active layer composition positioned on the metal substrate.

Active layer composition of reduction electrode for electrolysis and reduction electrode derived therefrom

Provided are an anode for electrolysis, which includes a metal base, and a catalyst layer disposed on at least one surface of the metal base, wherein the catalyst layer includes a composite metal oxide of ruthenium, iridium, titanium, and platinum, and a metal in the composite metal oxide does not include palladium, wherein, when the catalyst layer is equally divided into a plurality of pixels, a standard deviation of iridium compositions of the plurality of equally divided pixels is 0.40 or less, and a method of preparing the same.

Anode for electrolysis and preparation method thereof

The present invention relates to a method of purifying waste hydrochloric acid, and more particularly, to a method of purifying waste hydrochloric acid which includes preparing an extraction solution by dissolving an extractant in an organic solvent (S), extracting metallic components with the organic solvent by adding the extraction solution to the waste hydrochloric acid (S), separating a waste hydrochloric acid layer and the organic solvent containing the metallic components (S), and obtaining purified hydrochloric acid by recovering the separated (fractionated) waste hydrochloric acid layer (S), wherein the extractant is used in an amount of 40 moles or more based on 1 mole of iron (Fe) included in the waste hydrochloric acid, and the waste hydrochloric acid and the extraction solution are mixed in a volume ratio of 1:0.1 to 1:1.

Method of purifying waste hydrochloric acid

The present invention relates to a rotating electric toothbrush comprising: a main body having a receiving space formed therein, a driving means received in the interior of the main body and providing a rotational force, a toothbrush handle having one end detachably coupled to the driving means, and receiving a rotational force of the driving means to be rotated, a support means coupled to the outer peripheral surface of the other end of the toothbrush handle and having plate-shaped support bodies made of a ductile material and radially formed to be spaced apart from each other, and a plurality of toothbrush bristles implanted between the support bodies. The present invention has a structure in which the toothbrush bristles are radially implanted on the outer peripheral surface of the end of the cylindrical rotating toothbrush handle, thereby removing food leftovers sandwiched on a tooth surface or at an interdental gap without damage of gums, and more surely removing dental plaque from the tooth surface due to silicon bristles implanted between the toothbrush bristles. Further, the silicon bristles implanted between the toothbrush bristles support the toothbrush bristles, thereby preventing deformation of the toothbrush bristles, and a space for receiving toothpaste is formed between the silicon bristles, thereby preventing the toothpaste from easily slipping off. Further, a tongue cleaner, which is detachable and made of a silicon material, is further comprised, thereby easily cleaning a tongue.

The present invention relates to a composition comprising an inhibitor of the expression or activity of SH3 domain containing ring finger 2 (SH3RF2) for preventing or treating cancers. More specifically, since the SH3RF2 protein, of which the expression level increases in various cancer tissues, binds to PAK4, which is a cancer-associated gene, to regulate an apoptosis inhibitory function of the PAK4 protein by ubiquitination activity of SH3RF2 RING domain, cancer cells, in which the expression of SH3RF2 is inhibited, sensitively respond to the induction of apoptosis to promote apoptosis and reduce in vivo tumorigenicity, such that the inhibitor of the expression or activity of SHRF2 can be useful as a composition for preventing or treating cancers.
