An embodiment of the present disclosure provides a cover for a flexible display panel, including an organic film including a recessed portion, a reinforcing layer disposed in the recessed portion, and a first and second rigid structure adjacent to each other disposed on the organic film, the first rigid structure includes a first joint portion, and the second rigid structure includes a second joint portion, the first joint portion and the second joint portion being configured to be separated from each other when the reinforcing layer is bent, and to be joined to form a one-piece structure when the reinforcing layer is not bent. In an embodiment of the present disclosure, by providing on the organic film a reinforcing layer and rigid structures that can be joined and separated, the cover may exhibit enhanced surface hardness, impact resistance and user's feel while the bending of the cover can be realized.

Devices and methods fabricating devices having nanostructures that allow adhesion or growth of one cell type, such as endothelial cells, more than another cell type, such as smooth muscle cells. In particular, stent covers may have nanostructures that allow adhesion or growth of one cell type more than another cell type. Nanostructures forming the devices may be optimized.

A textile layered construction has a textile outer layer, a textile inner layer and an absorbing component, whereby line-shaped connections between the outer layer and the inner layer are designed as a laser welded joint, forming chambers fillable with insulating material between the welded joints. At least one line-shaped welded joint connection includes an interruption separating the line-shaped welded joint connection into two line-shaped welded joint connection parts.
