摘要:
In a heat exchanger having tubes and fins, a polyaniline film made of polyaniline and/or a derivative thereof is formed on the surfaces of the tubes and the fins. This polyaniline film is imparted with at least one hydrophilic functional group selected from the class consisting of a primary amino group, a secondary amino group, a tertiary amino group, an ammonium group, a nitric acid group, a carboxyl group, a sulfonic acid group, a phosphonic acid group and a hydroxyl group. Accordingly, the surfaces of the tubes and the fins has good water wettability while maintaining deodorizing and sterilizing functions.
摘要:
A surface polyaniline layer comprising a polyaniline and/or a derivative thereof capable of generating active oxygen or hydrogen peroxide upon the reaction with the water component in external air that comes in contact therewith, is formed on at least a portion of the outermost surface of a base body constituting tubes and/or fins, wherein a benzenoid/quinoid ratio in the surface polyaniline layer (defined as a ratio of an absorbancy of the benzenoid structure to an absorbancy of the quinoid structure in the polyaniline and/or the derivative thereof) is in a range of about 0.5 to about 3.0.

An additive for water-added bio fuel of the present invention includes: a surface active agent; glycol alcohol; alcohol synthesizable from biomass; and ammonia. A water-added bio fuel of the present invention is obtained such that water and the additive for water-added bio fuel according to the present invention are combined with a fuel oil in a predetermined ratio and that a particle of the water is made fine relative to the fuel oil so as to be dispersed and soluble in the fuel oil.
摘要:
A manufacturing method of an SiC single crystal includes preparing an SiC substrate, implanting ions into a surface portion of the SiC substrate to form an ion implantation layer, activating the ions implanted into the surface portion of the SiC substrate by annealing, chemically etching the surface portion of the SiC substrate to form an etch pit that is caused by a threading screw dislocation included in the SiC substrate and performing an epitaxial growth of SiC to form an SiC growth layer on a surface of the SiC substrate including an inner wall of the etch pit in such a manner that portions of the SiC growth layer grown on the inner wall of the etch pit join with each other.
摘要:
An additive for water-added bio fuel of the present invention includes: sodium hypochlorite; sodium hydroxide; hydrochloric acid; magnesium chloride; and calcium hydroxide, and makes the water soluble in the fuel oil. Further, a method of producing an additive for water-added bio fuel of the present invention includes: a step of agitating and mixing by putting sodium hydroxide into a solution of sodium hypochlorite; a step of agitating and mixing by putting magnesium chloride and calcium hydroxide into a solution of sodium hypochlorite; and a step of agitating and mixing the two types of solutions.
