A metal substrate includes a first insulating substrate, a second insulating substrate, a first metal layer, a second metal layer and a release layer. The first insulating substrate has a first modified surface and a second surface opposite to the first modified surface. The first metal layer faces the second surface. The release layer is bonded on the first modified surface. The second insulating substrate is bonded on a side of the release layer, such that the release layer is between the first modified surface and the second insulating substrate. The second metal layer is disposed on a side of the second insulating substrate, such that the second insulating substrate is between the release layer and the second metal layer. An original surface roughness of the first modified surface has a variation substantially less than 10% after the first modified surface is released from the release layer.

A multi-layered surface indentation concealment system having a body including a medial portion and a flexible peripheral margin extending outward of said medial portion. The body can be disposed to conceal a surface indentation in a surface, whereby the medial portion spans the surface indentation and the flexible peripheral margin secures about the surface indentation by application of a coat composition to the flexible peripheral margin.

A gap finishing tape for use with drywall applications includes a trim strip body extending along a central body axis, a hot melt adhesive extending along the central body axis, and a backing paper. The trim strip body includes a first surface, a second surface opposite the first surface, a first side, and a second side opposite the first side, and is at least partially constructed from a metallic material. The backing paper is at least partially secured to the second surface of the trim strip body. The trim strip body is at least partially embedded in the hot melt adhesive.

Certain embodiments described herein are directed to mobile device bumpers that can reversibly couple to a mobile device case or a mobile device. In some examples, the mobile device bumper comprises a bioactive material that can kill or inactivate bioorganisms. The bioactive material can be a photocatalyst and may also comprise one or more transition metals. The mobile device bumpers can be used to reduce spread of infections.
