Abstract:
A fast method of creating nanostructures comprising the steps of forming one or more electrically-charged regions ( 5 ) of predetermined shape on a surface ( 1 ) of a first material, by contacting the regions with a stamp for transferring electric charge, and providing electrically charged nanoparticles ( 7 ) of a second material, and permitting the particles to flow in the vicinity of the regions, to be deposited on the regions.
Abstract:
PROBLEM TO BE SOLVED: To provide an improved method allowing the fabrication of a nano-structural device having a very small geometric feature. SOLUTION: The nano-structure is formed on a surface of a semiconductor substrate or a surface of a passivated semiconductor substrate by the process comprising a step of forming one or more electrically charged sites having a preliminarily decided shape, where a first surface part corresponding to the one or more sites is brought into contact with a solid material tool (9) so that an electric charge moves between the tool and the first surface; a step of depositing particles (7) of a second material onto the first surface by making the particles (7) to flow near the one or more electrically charged sites to attract or repulse the particles (7) to or from the one or more electrically charged sites so as to conform the particles (7) to the electrically charged sites, provided in the step of forming, by virtue of the polarity of the charge against the potarity of the electrically charged sites; and a step of creating a chain (148) of a nanometer-size filament or particle, an array of filament (158) of carbon nanotubes or a filament or nanorod (168) of a semiconductor material or a magnetic material.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of dipping pen nano-lithography (DPN), a substrate processed by patterning by DPN, a kit for carrying out DPN, and an AFM chip coated by hydrophobic compound. SOLUTION: The interatomic force microscope (AFM) has the chip coated with the hydrophobic compound. The interatomic force microscope (AFM) functions as the dipping pen nano-lithography (DPN) for writing a pattern on a gold substrate (AU) by transferring molecules from the chip of the interatomic force microscope (AFM) to the gold substrate (AU).

Abstract:
PROBLEM TO BE SOLVED: To provide a cationic coating composition which considers process saving, the optimization of production cost, environmental measures, and the like, and to provide a method for forming a multi-layered coating film including an intermediate coating and a top coating. SOLUTION: This cationic coating composition comprises (A) an unsaturated group-modified blocked polyisocyanate cross-linking agent obtained by reacting a hydroxyl group-containing unsaturated compound (a) with a blocking agent (b) and a polyisocyanate compound (c), a cationic epoxy resin (B), and a photopolymerization initiator (C). A cathodic electrodeposition coating using the composition. A method for forming a coating film comprises applying the irradiation of light and heating to the coating film of the cathodic electrodeposition coating. And a method for forming a multi-layered coating film comprises a process for forming the coating film of a cathodic electrodeposition coating composition on an article to be coated, a process for irradiating the formed coating composition with light, a process for coating an intermediate coating and/or a top coating to form coating films, and a process for simultaneously heating the multi-layered coating film comprising the cathodic electrodeposition coating film, the intermediate coating film and/or the top coating film to cure the multi-layered coating film.
