Abstract:
In accordance with the present disclosure, a hybrid electronic sheet which exhibits superior electrical property and allows biomaterial functionalization and flexible device patterning may be provided by binding a graphitic material in colloidal state to a biomaterial capable of binding thereto specifically and nondestructively. Since the electronic sheet is an electronic sheet wherein a biomaterial and an electrical material (graphitic material) are hybridized, it exhibits good compatibility with biomaterials and can be further functionalized with, for example, an enzyme that selectively reacts with a biochemical substance. Accordingly, an electrical material and a chemical or biological material may be effectively nanostructurized and it can be realized as a multi-functional, high-performance electronic sheet.
Abstract:
Disclosed is a method for adsorbing a dye for a dye-sensitized solar cell. The method includes: coating a paste including metal oxide nanoparticles on the upper surface of a titanium oxide thin film and calcining the coated paste to form a porous film; adding an additive to a sensitizing dye solution to promote the adsorption of the dye; and dipping the porous film in the sensitizing dye solution to adsorb the sensitizing dye onto the surface of the porous film. The sensitizing dye solution is a dispersion of the sensitizing dye in an organic solvent. Also disclosed are a working electrode prepared using the sensitizing dye solution and a dye-sensitized solar cell including the working electrode. The addition of the additive shortens the time of dye adsorption. Despite the shortened adsorption time, the dye does not undergo desorption in the long term as well as in the short term, ensuring long-term stability of the solar cell.

Abstract:
Provided is a method of preparing cellulose fiber and carbon fiber by recycling industrial wood waste, wherein the carbon fiber is prepared by preparing high purity cellulose pulp by using, as a raw material, wood waste generated by manufacturers of pulp, furniture and other industrial products from wood and by eliminating resin and lignin impregnated in the wood waste through pulping and bleaching of the raw material, by preparing cellulose fiber by directly dissolving the prepared pulp in a cellulose solvent, and then by performing stabilizing and carbonizing with the cellulose fiber as a precursor.
Abstract:
2-dimensional nanostructured tungsten carbide which is obtained by control of the alignment of nanostructure during growth of tungsten carbide through control of the degree of supersaturation and a method for fabricating same are disclosed. The method for fabricating 2-dimensional nanostructured tungsten carbide employs a chemical vapor deposition process wherein a hydrogen plasma is applied to prepare 2-dimensional nanostructured tungsten carbide vertically aligned on a nanocrystalline diamond film. The chemical vapor deposition process wherein the hydrogen plasma is applied includes: disposing a substrate with the nanocrystalline diamond film formed thereon on an anode in a chamber, disposing a surface-carburized tungsten cathode above and at a distance from the substrate, and applying the hydrogen plasma into the chamber.
Abstract:
Provided is a 3D image display apparatus, which configures a light path such that light sources radiated from at least two projection optical systems pass through any one point (or nodal point) formed before the imaging position and forms a viewing zone having at least two viewing points at each observation position. Thereby, fixing a ratio of a degree of overlap (crosstalk) between neighbor viewing zones according to each depth sense (or observation distance) behind the imaging position, establishing a 3D viewing environment suitable for an observer, and enabling the observer to view a multi-view and super multi-view image. In addition, by merging the adjacent viewing points within one viewing zone, it is possible to minimize an area in which the viewing zones are overlapped and uniformize the intensity of light representing an image.
Abstract:
By forming a structure wherein an oxygen ionic conductor or a mixed ionic-electronic conductor (MIEC) on a cathode surface is not covered by a molten carbonate electrolyte using an oxygen ionic conductor or a mixed ionic-electronic conductor having poor wettability on the molten carbonate electrolyte, a new electrochemical reaction site may be provided in addition to that provided by the molten carbonate electrolyte. As a result, cell performance, particularly cathode performance, can be improved even at low operation temperatures (e.g., 500-600° C.).
