Abstract:
Nicotinamide and/or a compound which is chemically combined with nicotinamide may be used as a carbon nanotube (“CNT”) n-doping material. CNTs n-doped with the CNT n-doping material may have long-lasting doping stability in the air without de-doping. Further, CNT n-doping state may be easily controlled when using the CNT n-doping material. The CNT n-doping material and/or CNTs n-doped with the CNT n-doping material may be used for various applications.
Abstract:
Disclosed are a composite composition comprising carbon nanotubes and a transparent conductive film using the composite composition. The composite composition comprises a solution of an ion conductive polymeric binder in a solvent and carbon nanotubes dispersed in the solution. The transparent conductive film is formed by coating a dispersion of carbon nanotubes in an ion conductive polymeric binder on a base film to allow the transparent conductive film to be electrically conductive as a whole. The composite composition can be used to form a transparent conductive film with excellent bending properties as well as high electrical conductivity and high transparency. Therefore, the composite composition can be applied to transparent electrodes for use in foldable flat panel displays.
Abstract:
Disclosed is a method for hardening an interface of a carbon material by using nano silicon carbide coating. A carbon material-aluminum composite prepared by the disclosed method is light in weight, and has a high dynamic strength, and thus can be applied to currently used cars and aluminum wheels. Furthermore, the composite can be utilized as a material for aircrafts, spacecraft, ships, etc. requiring a high strength.
Abstract:
An apparatus includes a key providing unit to arrange one key group in a main touch area and to arrange remaining key groups in sub-touch area, a touch screen to display a virtual keyboard and to receive an input, and an input recognizing unit to recognize a user-inputted direction gesture. The key providing unit decreases the size of the key group in the main touch area and moves it to the sub-touch area, enlarges a size of a key group corresponding to the direction of the direction gesture and moved into the main touch area. A method to display the virtual keyboard also includes decreasing the size of the key group in the main touch area and rearranging it into the sub-touch area, enlarging a size of a key group in the sub-touch area receiving a click input, and arranging it into the main touch area.
Abstract:
Disclosed herein is a method of fabricating a transparent conductive film, including preparing a carbon nanotube composite composition by blending a carbon nanotube in a solvent; coating the carbon nanotube composite composition on a base substrate to form a carbon nanotube composite film, and acid-treating the carbon nanotube composite film by dipping the carbon nanotube composite film in an acid solution, followed by washing the carbon nanotube composite film with distilled water and drying the washed carbon nanotube composite film to form a transparent electrode on the base substrate. The transparent conductive film can have excellent conductivity, transparency and bending properties following acid treatment, so that it can be used in touch screens and transparent electrodes of foldable flat panel displays. Further, the carbon nanotube composite conductive film can have improved conductivity while maintaining transparency after acid treatment.

Abstract:
A method for pruning perimeter walks includes: hashing a name or attributes of an event, when the event occurs, to figure out a destination location of the event; performing greedy forwarding of geographic routing so as to send a packet of the event towards the destination location; checking a distance D between the destination location and a current node where a packet transmission using greedy forwarding mode is impossible, when the packet reaches the current node; checking distances between the destination location and respective neighboring nodes of the current node to obtain a neighboring node having a minimum distance M, when the distance D between the current node and the destination location is same or less than half of radio transmission range; comparing the minimum distance M to the distance D; and determining which node is a rendezvous node, according to the comparison result.
Abstract:
A new single optical interband transition occurs at the corresponding p-doping state of the carbon nanotubes in the VIS-NIR region when the degree of p-doping of carbon nanotubes is increased beyond a certain degree. P-doped carbon nanotubes to exhibit the new single optical interband transition in the VIS-NIR region may be used for devices so as to improve sensitivity and selectivity of the devices.
