Abstract: An embodiment vehicle seat includes a seatback configured to support an occupant's upper body, the seatback including an upper seatback part and a lower seatback part, wherein the upper seatback part includes a tilting part pivotably hinged onto the lower seatback part so as to be tiltable forward and backward with respect to the lower seatback part as the upper seatback part is pivoted forward and backward about the lower seatback part, and a tilting device configured to tilt the tilting part forward and backward in conjunction with a reclining operation of the seatback, wherein the tilting device is configured to tilt the tilting part forward in conjunction with a backward reclining operation of the seatback.

Abstract: An embodiment solid electrolyte includes a first compound and a second compound. The first compound is represented by a first chemical formula Li7-aPS6-a(X11-bX2b)a, wherein X1 and X2 are the same or different and each represents F, Cl, Br, or I, and wherein 0<a?2 and 0<b<1, and the second compound is represented by a second chemical formula Li7-cP1-2dMdS6-c-3d(X11-eX2e)c, wherein X1 and X2 are the same or different and each represents F, Cl, Br, or I, wherein M represents Ge, Si, Sn, or any combination thereof, and wherein 0<c?2, 0<d<0.5, and 0<e<1.

Abstract: Provided are a low-reflective coating layer, a porous layer, a method of fabricating the porous layer, and an optical member including the porous layer. According to an embodiment, a low-reflective coating layer comprising a porous film having hollow sphere structures or bowl-like structures is provided. Each hollow sphere structure or bowl-like structure may have cavity formed therein. The hollow sphere structures or the bowl-like structures may be formed from spherical micelles, and each spherical micelle may be formed by self-assembling a supramolecular complex of a first compound block and a second compound block. In addition, the first compound block may constitute a backbone of the supramolecular chemical compound and the second compound block may constitute a side chain of the supramolecular. The second compound block may be non-covalent bonded to the first compound block.
