Abstract: The present invention relates to a system and a method of integrally accumulating and granting a bonus in an on-line commercial transaction, in which in order to integrally accumulate an accumulated point according to a wired/wireless on-line site commercial transaction, an Internet of communication (IoC)-bonus gateway automatically calculates various commercial transaction bonuses and transmits the calculated commercial transaction bonuses to a user terminal device, and the commercial transaction bonuses are transmitted from the user terminal device to a bonus server, so that the on-line commercial transaction bonus is granted, accumulated, and integrated, without passing through an on-line electronic payment granting intermediary gateway (payment gateway (P/G)).

Abstract: Disclosed is an anticorrosion paint for preventing steel materials from corrosion by using polyaniline as an anticorrosion pigment. The anticorrosion paint has an excellent anticorrosion effect, long persistence of the anticorrosion effect, high durability and superior coating property controlling the anticorrosion effect, without using metal causing environmental pollution as an anticorrosion pigment. Especially, in the anticorrosion paint, the top coat paint for improving the protection of the primer coat paint and the anticorrosion effect. The top coat paint includes 40 to 89 wt % of matrix resin, 5 to 54 wt % of colored pigment, 1 to 50 wt % of dopants and 5 to 54 wt % of mixed solvents, and the primer coat paint includes 3 to 49 wt % of the polyaniline, 40 to 86 wt % of the matrix resin, 1 to 47 wt % of the dopants and 10 to 56 wt % of the mixed solvents. The anticorrosion paint plays a role in exerting persistently the excellent anticorrosion effect without causing environmental problem.

Abstract: A method for producing nano-sized titanium dioxide (TiO2) ultrafine powder from titanium tetrachloride (TiCl4) in the vapor phase by the gas phase oxidation reaction using flames, in which the method comprises: simultaneously introducing titanium tetrachloride (TiCl4), vapor, argon, oxygen, hydrogen and air into a five-piped flame reactor to form a flame having a temperature of greater than 1,000° C.; and producing nano-sized titanium dioxide ultrafine powder having an average particle size of less than 50 nm.

Abstract: A binder composition for a photocatalytic coating is disclosed. The binder composition comprises 60-80 wt. % of a first monomer which is a non-fluoro containing monomer selected from the group consisting of acrylic monomers, methacrylic monomers, and mixtures thereof, having an aliphatic group and 20-40 wt. % of a second monomer which is at least one monomer selected from the group consisting of a fluoro containing monomer and a silicone monomer. The fluoro containing monomer is selected from the group consisting of styrene monomer, acrylic monomer and methacrylic monomer.
