A secure element has a card-type body made of a plurality of layers, arranged one above the other and generated by coextrusion. The secure element includes a first layer as the base layer made of a first material having a base polymer, wherein a first color is homogenously distributed in the first layer as the main color of the body. The secure element includes at least one second layer, as the colored layer made of a second material that has a carrier polymer. The base polymer and the carrier polymer have different material properties with randomized polychromatism visible in plan view and in cross section. The at least one second layer forms, together with the first layer in the card body in a random distribution, colored surface regions, which are dominated in part by the color of the first layer and in part by the color of the second layer.

An at least partially crystallized glass includes at least one crystal phase and pores which are distributed in the at least partially crystallized glass in a structured manner.

A floor, wall or ceiling panel comprises a core and a decorative top layer provided on the core. The core comprises a magnesium oxide-based board material, and wherein the aforementioned panel, on at least two opposite edges, is provided with coupling means allowing that two of such panels can be interlocked at the respective edges.

The present invention relates to a multi-layered article comprising at least a specific oriented polyethylene-based film (OPEF) and a specific non-oriented polyethylene-based film (NOPEF). Furthermore, the present invention relates to a method for producing said article and its use as a packaging material.

Methods and systems are provided for a process to generate a nonwoven textile. In one example, the nonwoven textile may have layered, zonal properties resulting from entangling of two or more types of staple fibers through a merging region between the layers of staple fibers while maintaining distinct zones, each zone comprising a type of staple fiber. Furthermore, the process may include embedding a filament layer into the nonwoven textile via a continuous assembly line.

Certain embodiments described herein are directed to composite materials effective for use in deep draw processes. In some examples, the composites can be used to provide vehicle panels such as, for example, vehicle underbody panels. In some configurations, the composite comprises a fiber reinforced polymer core and a skin material disposed on at least some portion of the fiber reinforced polymer core, in which the skin material comprises a basis weight of at least 65 g/m2 and an elongation at break of at least 20%.

A method for improving the air and/or water barrier performance of a building panel is disclosed. The building panel may be a gypsum board or cement board. In particular, the board may have improved resistance to bulk water penetration or permeation while maintaining breathability with respect to water vapor.

Embodiments of the present disclosure provide an epitaxial structure of a semiconductor device and a method of manufacturing the same. The epitaxial structure includes a substrate, and an epitaxial layer located on a side of the substrate, the epitaxial layer including a nucleation layer located on a side of the substrate and a buffer layer located on a side of the nucleation layer away from the substrate, wherein a thickness of the buffer layer is inversely proportional to a thickness of the nucleation layer.

A joined body includes a first member, a second member, and a joining portion disposed therebetween and joining the first member and the second member. The joining portion includes a first joining layer on a side toward the first member and formed of a first joining material, a second joining layer on a side toward the second member and formed of a second joining material, and a metal layer therebetween and having a plurality of holes communicating with one another. The metal layer includes a first-joining-material-impregnated layer on a side toward the first joining layer and in which the plurality of holes are impregnated with the first joining material, a second-joining-material-impregnated layer on a side toward the second joining layer and in which the plurality of holes are impregnated with the second joining material, and an unfilled hole layer therebetween and in which the plurality of holes are void.

The present disclosure relates to a plaster board comprising a first panel having an outer surface, an inner surface, a first edge, a second edge, and a center between the first edge and the second edge, a layer of hardened plaster material coupled to the inner surface of the first panel, wherein the hardened plaster material has a first density proximate the first edge of the first panel and a second density proximate the center of the first panel, the first density being greater than the second density, and a second panel having an outer surface, an inner surface, a first edge, a second edge, and a center between the first edge and the second edge, wherein the second panel is coupled to the hardened plaster material opposite the first panel.
