A sandwich structure employs a core sheet including alternating peaks and valleys therein. In another aspect, a sandwich structure includes at least one metallic core and at least one adhesively bonded outer face sheet. Yet another aspect of a sandwich structure has raised ridges bridging between adjacent peaks in a core sheet in one direction but not in a perpendicular direction, thereby achieving different properties in the different sheet directions.

A bar of noble metal or an alloy containing noble metal having a mass mB is subdivided into nm miniature bars 2, 3 each having a specified mass mk, wherein n and m each denote an integer 2, there being an interconnection of solid material (8) between directly adjacent miniature bars (2, 3). Another bar is affixed to a backing (13), to which the miniature bars are releasably attached. A method for the production of the bar consists in dividing up the same while leaving an interconnection of solid material or producing an arrangement thereof on a backing.

Embodiments of the present invention are generally directed to materials processing methods using femtosecond duration laser pulses, and to the altered materials obtained by such methods. The resulting nanostructured (with or without macro- and micro-structuring) materials have a variety of applications, including, for example, aesthetic applications for jewelry or ornamentation; biomedical applications related to biocompatibility; catalysis applications; and modification of, for example, the optical and hydrophilic properties of materials including selective coloring.

A finish part including a metal body, a metal engagement arm extending integrally from the body, a detent depending from the arm, the detent being formed from the metal of the arm that is plastically deformed out of a plane of the arm. A method for installing a finish part including aligning the engagement arm of the finish part with an opening in a structure upon which the part is to be installed, and urging the engagement arm and the detent into the opening. A structure including a frame having exposed unfinished surfaces, and the metal finish part disposed upon the unfinished surface and that finishes the unfinished surface.
