A packaging material comprising a graphene-reinforced polymer matrix composite (G-PMC) is disclosed. The packaging material has improved barrier resistance to gas and liquid permeants. Also disclosed is a method of improving barrier resistance of a polymer to a permeant, the method comprising forming a graphene-reinforced polymer matrix composite within the polymer. The packaging material may be used for packaging food, drug, perfume, etc. and to make various containers.

An electronic device is provided. The electronic device includes a display, a substrate, and an anti-explosion layer. The substrate is disposed on the display. The anti-explosion layer is disposed between the substrate and the display, and the anti-explosion layer has a tensile strength in a range from 10 MPa to 30 MPa.

A piezoelectric speaker (10) includes: a piezoelectric film (35); a fixing face (17) for fixing the piezoelectric film (35) to a support; and an interposed layer (40) disposed between the piezoelectric film (35) and the fixing face (17). The interposed layer (40) has a holding degree of 510.sup.8 N/m.sup.3 or less.

A system for protecting a person's facial skin from contaminants due to the application of makeup is disclosed. The system may include one or more patches that may be applied to the person's eyelids, cheeks, lips or other locations, upon which makeup may then be applied. In this way the makeup is applied to the top surface of the patches and not directly to the person's skin. The system may thereby prevent microbes (e.g., bacteria, viruses, etc.) from being transferred from the makeup and/or the makeup applicator to the person's skin.

A protective cover for a vehicle is disclosed. The protective cover comprises a pad comprising a first layer, a second layer, and a third layer. The first layer is a waterproof outer layer. The second layer is an impact resistant layer. The third layer is a soft bottom layer. The pad is foldable at folding sections. The pad comprises a plurality of loops. The protective cover comprises at least one strap drawn through the plurality of loops. The protective cover further comprises a weighted ball device mounted at one end of a strap. The protective cover is placed over the vehicle and the strap is weighed down with the help of the weighted ball device mounted thereon. The weighted ball device is decoupled from the strap to allow ends of the strap to couple together. The pad protects the vehicle from objects falling onto or colliding with the vehicle.

A ceramic electronic component that includes an electronic component body having a superficial base ceramic layer; a surface electrode on a surface of the electronic component body, a peripheral section of the surface electrode having an opening therein; and a covering ceramic layer covering the peripheral section of the surface electrode and the opening therein.

A ceramic electronic component that includes an electronic component body having a superficial base ceramic layer; a surface electrode on a surface of the electronic component body; and a covering ceramic layer covering a peripheral section of the surface electrode. The peripheral section of the surface electrode that is covered by the covering ceramic layer has a thin portion located on a central side of the surface electrode and which is thinner than a central section of the surface electrode, and a width of the thin portion is 20% or more of a width of the peripheral section of the surface electrode that is covered by the covering ceramic layer.

A flooring assembly comprising a flooring unit comprising a stability core layer having a plurality of edge surfaces, two of which have an interlocking mechanism for attachment to the edge surfaces of the stability core of adjacent flooring units; a sound attenuating acoustic layer attached to the bottom surface of the stability core layer; and a finish layer attached to the top surface of said stability core layer.

Disclosed is an artificial leather base material having a surface with a lightness L* value of 50 and including a fiber base material that includes cationic dye-dyeable polyester fibers and an elastic polymer, the artificial leather base material being dyed with at least one cationic dye. Also provided is a resin layer-equipped artificial leather, a napped artificial leather, and a shoe that use the artificial leather base material is used. Also provided is a decorating sheet including the artificial leather base material, and a decorative molded body using the same.

A piezoelectric speaker (10) includes a piezoelectric film (35), a first joining layer (51), and an interposed layer (40). The piezoelectric film (35) includes a first electrode (61), a second electrode (62), and a piezoelectric body (30) sandwiched by the first electrode (61) and the second electrode (62). The first joining layer (51) is a layer having pressure-sensitive adhesiveness or adhesiveness. The interposed layer (40) is disposed between the piezoelectric film (35) and the first joining layer (51). Both principal surfaces of the piezoelectric film (35) vibrate up and down as a whole.
