Abstract: A protective film included in the display device is manufactured by preparing a graphene oxide particle in powdered state, adjusting a size of the graphene oxide particle to achieve a preselected dispersibility in the carbon nanocomposite, and mixing the size-adjusted graphene oxide particle with a photocurable resin.

Abstract: Disclosed is a method for preparing a porous carbon structure, the method comprising the steps of: (a) mixing a carbon precursor, a pyrolytic template, which is pyrolyzed at the carbonization temperature of the carbon precursor or removed by post-treatment after the carbonization of the carbon precursor so as to form pores, and a solvent, to prepare a spray solution; and (b) subjecting the spray solution either to spray pyrolysis or to spray drying and then spray pyrolysis, so as to form a carbonized carbon structure, and then removing the template from the carbon structure. A mesoporous spherical carbon prepared according to the disclosed method may have a large specific surface area and a large pore volume through the control of the kind and concentration of template, and thus can be used in a wide range of applications, including catalysts, adsorbents, electrode materials, materials for separation and purification, and materials for storing hydrogen and drugs.

Abstract: A diagnostic and analytical apparatus including the microfluidic device having: an inlet portion with a first cross-section, a flow delaying portion with a second cross-section that is larger than the cross-section of the inlet portion thereby reducing the interfacial curvature of the microfluid entering from the inlet portion by capillary force and the flow rate of the microfluid, and a flow recovery portion having a third cross-section that is smaller than the cross-section of the flow delaying portion. The flow of a very small volume of fluid can be quantitatively regulated through a channel having a particular design that can induce spontaneous flow by capillary force without additional manipulation processes and energy requirement.
