Abstract: The present invention relates to a non-halogenated phosphorus flame retardant containing adenosine triphosphate (ATP) as an organic compound that supplies energy for life activity, a flame-retardant polymer resin having the non-halogenated phosphorus flame retardant coated thereon, and a method for preparing the same. The non-halogenated phosphorus flame retardant according to an embodiment of the present invention contains adenosine triphosphate (ATP).

Abstract: A thermoplastic resin composition of the present invention is characterized by containing: about 100 parts by weight of a thermoplastic resin including rubber-modified vinyl-based graft copolymer and aromatic vinyl-based copolymer resins; about 10-50 parts by weight of a flame retardant other than a phosphorus-based compound; about 1.5-3.5 parts by weight of zinc oxide particles having an average particle size of about 0.2-3 ?m and a BET specific surface area of about 1-10 m2/g; and about 2.5-6.5 parts by weight of sodium phosphate. The thermoplastic resin composition has excellent antibacterial properties, flame retardant properties, and impact resistance properties.

Abstract: A thermoplastic resin composition according to the present invention comprises: about 100 parts by weight of a thermoplastic resin comprising about 30 to about 60 wt % of a rubber-modified aromatic vinyl-based copolymer resin, about 30 to about 60 wt % of a polycarbonate resin, and about 5 to about 25 wt % of a polyester resin; about 0.1 to about 5 parts by weight of zinc oxide; about 0.1 to about 3 parts by weight of a phosphite compound comprising at least one type from among a phosphite compound represented by chemical formula 1 and a phosphite compound represented by chemical formula 2; and about 5 to about 30 parts by weight of a phosphorus-based flame retardant. The thermoplastic resin composition has excellent hydrolysis resistance, flame retardancy, and impact resistance, excellent balance of the foregoing physical properties, and the like.

Abstract: The present disclosure provides an achromatic colorimetric nanosensor, by using a mixture of nanoparticles with complementary colors. The color changes from an achromatic color to a chromatic color enables more clear color-transition and, thus, allows immediate analysis of the presence of a target analyte. Further, the present disclosure provides achromatic colorimetric nanosensor for detection of multiple analytes using plural nanoparticles via color changes from an achromatic to multiple chromatic colors.

Abstract: Provided is a colorimetric sensor whose color is changed from an A color to a B color after being exposed to analytes and which adds a dye or pigment complementing the A or B color so as to induce the color change from a black color to another color thereby maximizing a color contrast effect. The colorimetric sensor according to embodiments of the present invention includes a color change detecting part in which an indicator of which a color is changed according to presence and absence of the analytes and a dye which complements the color of the indicator are mixed, wherein the analytes are detected using a color change of the color change detecting part.
