Abstract: A display apparatus according to a concept of the disclosure includes: a display panel configured to display an image in a front direction; a top chassis positioned in a front direction of the display panel; a bottom chassis positioned in a rear direction of the display panel; a rear cover covering a rear side of the bottom chassis; and a stand member being accommodatable in the rear cover and selectively coupled with a rear surface of the rear cover, wherein the rear cover includes an accommodating portion in which the stand member is accommodated and a coupling portion coupled with the stand member, and the stand member includes an inserting protrusion which is inserted into the accommodating portion and the coupling portion.

Abstract: The present invention relates to an adsorbent including a hierarchically porous silica monolith, and particularly, to an adsorbent for adsorbing or separating carbon dioxide in air or heavy metals in an aqueous solution, in which an amino group is covalently bonded to the silica monolith. Further, the present invention relates to a method for preparing the adsorbent including a hierarchically porous silica monolith, and particularly, to a method for preparing an adsorbent for adsorbing or separating carbon dioxide in air or heavy metals in an aqueous solution, in which an amino group is covalently bonded to the silica monolith.
