Abstract:
A silicon nanowire including metal nanoclusters formed on a surface thereof at a high density. The metal nanocluster improves electrical and optical characteristics of the silicon nanowire, and thus can be usefully used in various electrical devices such as a lithium battery, a solar cell, a bio sensor, a memory device, or the like.
Abstract:
Disclosed is a carbon nanotube (CNT) thin film having metallic nanoparticles. The CNT thin film includes a plastic transparent substrate and a CNT composition coated on the substrate. The CNT composition includes a CNT and metallic nanoparticles distributed on the CNT surface. The plastic transparent substrate is flexible. The metallic nanoparticles are formed by heating a metallic precursor adsorbed in the CNT surface. A method of manufacturing the CNT thin film having metallic nanoparticles is also disclosed. A CNT-dispersed solution is prepared by mixing a CNT with a dispersant or a dispersion solvent. The CNT-dispersed solution is used to form a CNT thin film. Metallic precursors are implanted in the CNT thin film. Then, a heat-treatment is applied to transform the metallic precursors into metallic particles including metallic nanoparticles.
Abstract:
Disclosed herein is an ultraviolet (UV) light-blocking composition comprising a metal nanoparticle that absorbs and blocks a UV light wavelength using a surface plasmon-absorbing wavelength, and a dielectric. The UV light-blocking composition is capable of absorbing and blocking a UV light wavelength or, a specific wavelength, using the surface plasmon-absorbing wavelength of the metal nanoparticle or, the plasmon-absorbing wavelength transited by the dielectric, thereby demonstrating increased visibility when applied to an image display apparatus such as a mobile phone, and the like.

Provided is a method of fabricating carbon nanotubes using a focused ion beam (FIB). The method includes: preparing a substrate; scanning the substrate with the FIB; and growing the carbon nanotubes on the scanned substrate.
Abstract:
A developing device for a liquid electrophotographic image forming apparatus is provided. The developing device may have a developing roller, which supplies ink to a photosensitive body on which an electrostatic latent image is formed and develops the electrostatic latent image. The apparatus may include an ink reservoir in which ink supplied to the developing roller is accommodated, and an ink removal unit, which removes ink remaining in the ink reservoir after a development operation is performed. The ink removal unit may comprise an ink removal member rotatably installed in the ink reservoir that exhausts ink through a through hole formed under the ink reservoir. A driving member rotates the ink removal member. An ink cartridge stores ink exhausted through the through hole.

A liquid electrophotographic image forming apparatus using an ink developing solution having a high concentration where a non-volatile carrier is used as a dispersion solvent includes a photosensitive body, a charge unit increasing a potential of the photosensitive body to a charge potential, an exposure unit projecting a beam onto the photosensitive body and forming a latent electrostatic image, a developing solution supply unit supplying a developing solution to the photosensitive body, the developing solution having a high concentration where a non-volatile carrier is used as a dispersion solvent, a developing unit receiving the developing solution having the high concentration to form a developing film having the high concentration and to develop the latent electrostatic image, a transfer unit contacting the photosensitive body and moving the developed image to a recording medium, and a fixing unit fixing the transferred image in the recording medium at a temperature lower than a flash point of the non-volatile carrier. By using the non-volatile developing solution having the high concentration, a smell generating due to vapor of a carrier can be prevented, and an image forming apparatus having a simple structure can be provided.
