The present disclosure is directed to dielectric elastomeric composites that include a retainable processing membrane, an elastomer material, and an electrically conductive material. The elastomer layer may be partially imbibed into the retainable processing membrane. The retainable processing membrane may be porous. The retainable processing membrane is compacted in the transverse in direction, machine direction, or in both directions prior to the application of an elastomer material and an electrically conductive material. The compaction of the retainable processing membrane may form structured folds or folded fibrils in the membrane, giving the retainable processing membrane a low modulus and flexibility. In some embodiments, the dielectric composites are positioned in a stacked configuration. Alternatively, the dielectric elastomeric composites may have a wound configuration. The dielectric composites have a total thickness less than about 170 m. The dielectric elastomeric composites may be used, for example, in dielectric elastomer actuators, sensors, and in energy harvesting.

There are provided a soundproof structure, which can have high soundproofing performance in a wide frequency band and in which visual recognition of through-hole can be suppressed, and a sound absorbing panel and a sound adjusting panel using the soundproof structure. A sheet member having a plurality of through-holes passing therethrough in a thickness direction and a sound absorbing body disposed in contact with one main surface of the sheet member are provided. An average opening diameter of the through-holes is 0.1 m or more and less than 100 m. Assuming that the average opening diameter of the through-holes is (m) and an average opening ratio is a parameter A expressed by A=+.sup.2 is 92 or less.

A board consisting at least of a substrate formed at least of a gypsum-based and/or cement-based basic material layer. The board is provided with a chamfer extending through the basic material layer.

An insulation panel has a top barrier, a bottom barrier, and an insulation core layer disposed between to the top and bottom barriers. The insulation core layer includes a plurality of discrete hydrated compressed puffed polysaccharide particulates that are mechanically and/or chemically adhered to one another and to the top and bottom barriers. The plurality of discrete particulates defines a plurality of voids within the core layer.

A beverage-packaging container is provided that includes a container body for receiving the liquid and a cork stopper for sealing the liquid contents within the container body. The sidewalls and bottom wall of the container body are formed of paperboard and are preferably formed of a layered, recycled paperboard. The top wall of the container body is formed of a cork material with a cork-receiving hole disposed within the top wall. The cork stopper has a truncated cone-shaped portion that is configured to engage frictionally with the edges of the cork-receiving hole. The cork stopper may also have a wooden crown to aid the user in grasping and removing the cork stopper from the top hole of the container body.
