Abstract: The present disclosure provides a biogas reformer in which a portion of biogas feed can be combusted in a burner to supply the required heat amount to a catalytic reactor without supplying heat from an external heat source, and the CO2:CH4 ratio can be adjusted to be advantageous for a catalytic reforming reaction of the biogas by supplying a combustion effluent together with the biogas feed to the catalytic reactor.

Abstract: The present invention relates to a composition comprising an araloside-based compound and, more particularly, to a composition for external application to skin, the composition comprising, as an active component, an araloside-based compound, including araloside X, araloside V and araloside VII. Thus, the composition restores skin markers damaged by external environmental stress, such as harmful substances or fine dusts, and reduces the expression of skin inflammatory factors to help the recovery of damaged skin, thereby providing effects, such as anti-oxidation, skin trouble suppression, anti-inflammation, or skin barrier improvement.

Abstract: An organic light emitting display device includes a controller to control a first area and a second area of a display based on a predetermined condition. The controller simultaneously controls the pixels in the first area to display an image and controls the pixels in the second area to display light having a same gray scale value. The predetermined condition may be a user command or an operational condition, power mode, or status of a host device. The same gray scale value may be a lowest gray scale value in a predetermined range. The first and second areas may have different contours, and may be located at respective main and peripheral display locations of the host device.

Abstract: The present invention relates to a composition for collection of carbon dioxide using a liquid surfactant. The aerosol composition containing a liquid surfactant, of the present invention, has no deterioration in quality even at high temperatures, absorbs carbon dioxide to form a predetermined shaped foam when sprayed on the skin, is smoothly absorbed when rolled several times, and is naturally absorbed into the skin after several minutes even when left by completely losing carbon dioxide, and thus the aerosol composition can be favorably used as a foam type cosmetic product.

Abstract: Disclosed herein is an antireflective photocatalyst composition including a titanium dioxide-based photocatalyst, a binder, water, and alcohol, and a substrate using the composition. The antireflective photocatalyst composition is advantageous in that, when it is applied to a glass substrate, such as a glass antireflective film for a solar cell or a glass illuminator, it can prevent incident light energy from scattering and improve optical transmissivity, and in that it decomposes pollutants due to the dual action of harmful gas decomposition and self-purification, which are specific characteristics of a photocatalyst.
