Abstract:
A method for fabricating a nanoantenna array may include forming a resist layer on a substrate, forming a focusing layer having a dielectric microstructure array on the resist layer, diffusing light one-dimensionally in a specific direction by using a linear diffuser, forming an anisotropic pattern on the resist layer by illuminating the light diffused by the linear diffuser on the focusing layer and the resist layer, depositing a material suitable for a plasmonic resonance onto the substrate and the resist layer on which the pattern is formed, and forming a nanoantenna array on the substrate by removing the resist layer and the material deposited on the resist layer. A light diffusing angle by the linear diffuser and a size of the dielectric microstructure are determined based on an aspect ratio of the pattern to be formed.
Abstract:
An image generator is provided which obtains a specular image and a diffuse image from an image acquired by a polarized light field camera by separating two reflection components of a subject, and a control method thereof. The image generator may include a main lens, a polarizing filter part, a photosensor, a microlens array, and a controller that generates a single image in response to the electrical image signal and extracts, from the generated image, a specular image and a diffuse image that exhibit different reflection characteristics of the subject.

Abstract:
Disclosed is an antibacterial composition comprising titanium oxide particles immobilized with an antibody having affinity and cognitive power to a microorganism of interest, and a method for sterilizing the microorganism by using the same. In particular, the present invention relates to a method for preparing functional titanium oxide particles capable of recognizing a microorganism or a virus of interest, and a method for selectively and efficiently sterilizing the same by using the functional titanium oxide particles, and not for randomly sterilizing microorganisms or viruses by using conventional titanium oxide particles having no recognition power to a microorganism or a virus of interest.
Abstract:
Disclosed is a metal separator for a solid oxide regenerative fuel cell coated with a conductive spinel oxide film. In the conductive spinel oxide film, yttrium is added to a manganese-cobalt spinel oxide to suppress growth of an insulating oxide film on the surface of the metal separator and volatilization of metal. In the conductive oxide film coated on the metal separator, yttrium is segregated at the grain boundaries of the spinel so that migration of oxygen through the grain boundaries can be suppressed. Therefore, the surface of the metal separator can be protected from exposure to the atmosphere and water vapor when the solid oxide regenerative fuel cell is operated at high temperature. In addition, poisoning of electrodes by metal volatilization from the surface of the metal separator and growth of an insulating oxide film on the surface of the metal separator can be prevented. Therefore, the stability of the solid oxide regenerative fuel cell stack can be markedly improved.
