A welding method includes: moving a welding head toward a plurality of workpieces, wherein each of the plurality of workpieces includes a polymeric composite, the polymeric composite includes a polymer matrix and a plurality of fibers, and each of the fibers includes a magnetic material; applying a joining pressure to the workpieces with the welding head; applying energy to the plurality of workpieces to melt an interface between the plurality of workpieces, wherein a weld plane is defined at the interface between the plurality of workpieces; and applying a magnetic field to the plurality of workpieces to change an orientation of the plurality of fibers relative to the polymer matrix in the weld area so that the fibers in a weld area are at an angle relative to the weld plane.

An image displaying device includes a background layer and a display layer. The display layer includes an inner surface and an outer surface. The inner surface is substantially smooth, and the outer surface includes a plurality of raised areas and recessed areas. The display layer has a first zone with a first thickness measured between the inner surface and a raised area and a second zone with a second thickness measured between the inner surface and a recessed area. The display layer also includes a coloring agent having a higher concentration in the first zone as compared to the second zone. The display layer has increased light transmissivity through the recessed areas and decreased light transmissivity through the raised areas such that a contrast of light transmissivity between the raised and recessed areas generates an image.

Process for encapsulation of a microelectronic device comprising the following steps in sequence: supply a support substrate comprising a first principal face on which a microelectronic device is placed, a second principal face, and a lateral face, deposit a bonding layer on the first principal face of the substrate, position an encapsulation cover comprising a first principal face, a second principal face, and a lateral face, on the bonding layer, deposit a lateral protection layer on: the lateral face and the periphery of the second principal face of the support substrate, the lateral face and the periphery of the second principal face of the encapsulation cover, the lateral protection layer delimiting a protected zone, thinning of the second principal face of the support substrate and/or the second principal face of the encapsulation cover outside the protected zone.

Disclosed herein is a nano membrane. The nano membrane includes an insulating layer having a thickness corresponding to a diameter of each of metal nanowires and configured to contain the metal nanowires therein, and the metal nanowires arranged to cross and having portions of side surfaces which protrude from one surface of the insulating layer.
