The invention relates to a multi-layer, preferably co-extruded, plastic film with improved modulus properties, which is suitable, in particular, for producing three-dimensionally shaped articles.

A steel sheet has a chemical composition with a steel structure containing, by volume fraction, soft ferrite: 0-30%, retained austenite: 3-40%, fresh martensite: 0-30%, pearlite and cementite: 0-10%, and a remainder including hard ferrite. In the steel sheet, a number proportion of retained austenite having an aspect ratio of 2.0 or more in the total retained austenite is 50% or more, and a soft layer having a thickness of 1-100 μm is present. In the soft layer, a volume fraction of ferrite grains having an aspect ratio of less than 3.0 is 50% or more, and a volume fraction of retained austenite is 50% or more of the volume fraction of the retained austenite of the inside of the steel sheet. A peak of an emission intensity at a wavelength indicating Si appears in a range of more than 0.2 μm to 5 μm or less from the surface.

A display device includes a display panel; a supporter disposed on a surface of the display panel; and an adhesive layer disposed between the supporter and the display panel, wherein the supporter includes metal layers spaced apart from each other; and a cushion layer surrounding the metal layers, the adhesive layer includes a first area overlapping the metal layers in a vertical direction to the display panel; and a second area not overlapping the metal layers in the vertical direction to the display panel, and a modulus of the second area of the adhesive layer is larger than a modulus of the first area of the adhesive layer.

A protective coating layer, an electronic device including such a protective coating layer, and the methods of making the same are provided. The electronic device includes a substrate, a thin film circuit layer disposed over the substrate, and a protective coating layer disposed over the thin film circuit layer. The protective coating layer includes a first coating and a second coating disposed over the first coating. Each coating has a cross-plane thermal conductivity in a direction normal to a respective coating surface equal to or higher than 0.5 W/(m*K). The first coating and the second coating have different crystal structures, or different crystalline orientations, or different compositions, or a combination thereof to provide different nanoindentation hardness. The first coating has a hardness lower than that of the second coating.

A glass sealing system includes a glass portion and a first adhesive layer disposed along an exterior surface of the glass portion. The glass sealing system also includes a cover with a first surface secured to the first adhesive layer and a second surface opposing the first surface. The glass sealing system includes a second adhesive layer disposed on the second surface and configured to secure the cover to a support structure. The cover obscures the second adhesive layer from view of a user looking through the glass portion toward the support structure.

The disclosed invention includes articles having advantageous ceramic layers with a ceramic/metal intermediate layer that diminishes towards a pure metal core. Such articles have substantial use in unconventional, harsh environments.

One or more aspects of the disclosure pertain to an article including a film disposed on a glass substrate, which may be strengthened, where the interface between the film and the glass substrate is modified, such that the article retains its average flexural strength, and the film retains key functional properties for its application. Some key functional properties of the film include optical, electrical and/or mechanical properties. The bridging of a crack from one of the film or the glass substrate into the other of the film or the glass substrate can be prevented by inserting a crack mitigating layer between the glass substrate and the film.

A method to create a multi-zone microstructure spring includes releasing a buckling layer from a substrate, wherein the buckling layer displaces into a curved shape after the releasing. The buckling layer is displaced, relative to the substrate, through at least one of a first zone, a second zone, and a third zone, wherein the buckling layer provides positive stiffness in the first zone, zero stiffness in a second zone, and negative stiffness in a third zone, and the buckling layer must pass through the first zone to reach the second zone and the buckling layer must pass through the second zone to reach the third zone. A multi-zone microstructure spring includes a substrate and a buckling layer. The buckling layer has a surface area. The buckling layer has a positive stiffness in a first zone, zero stiffness in a second zone, and a negative stiffness in a third zone. The buckling layer must pass through the first zone to reach the second zone and the buckling layer must pass through the second zone to reach the third zone. The buckling layer is connected to the substrate. The microstructure includes an elastic connection. The elastic connection is in contact with the buckling layer over a fraction of the buckling layer's surface area.

A multilayered composite shape memory material includes a coextruded first polymer layer of a first polymer material and a second polymer layer of a second polymer material. The composite shape memory material after thermomechanical programming being capable of undergoing at least one temperature induced shape transition from a temporary shape to a permanent shape. The first polymer layer defines a hard segment of the shape memory material that provides the shape memory material with the permanent shape, and the second polymer layer defines a switching segment of the shape memory material that provides the shape memory material with the temporary shape.
