A sound damping wallboard and methods of forming a sound damping wallboard are disclosed. The sound damping wallboard comprises a gypsum layer with a gypsum surface having an encasing layer. The encasing layer is partially removed to expose the gypsum surface and form a gypsum surface portion and a first encasing layer portion on the gypsum layer. A sound damping layer is applied to the gypsum layer to cover at least part of the gypsum surface portion and the encasing layer portion.

A thermal insulation article includes a thermally insulating pad shaped to be positioned in a cavity of a rectangular prism shipping container. The pad includes a solid compostable panel formed primarily of starch and/or plant fiber pulp that holds together as a single unit, and a water-proof or water-resistant film forming a pocket enclosing the panel. The panel includes a first section, a second section, and a third section connecting the first section to the second section, the first and second section each having a central portion and two flaps that extend from the central portion beyond the third section, and wherein the panel is foldable into an open box.

A water-based adhesive for the manufacture of laminated cellulosic boards includes monolayer graphene oxide as a glue enhancer. Laminated cellulosic boards may be obtained by providing cellulosic plies, applying a water-based adhesive, and contacting the surface of another cellulosic ply to the first cellulosic ply. A method for producing the water-based adhesive includes mixing starch, water and glue enhancer. The glue enhancer is a suspension of between 0.1 wt % and 0.001 wt % of monolayer graphene oxide in water.

In a method of producing a resin frame member for a fuel cell, a processing die is used. The method includes a processing step of moving an upper die toward a lower die to thereby form an inclined surface on each of side parts of a resin film. In the processing step, shearing is performed while maintaining a predetermined clearance between the lower processing section and the upper processing section and in a state where each of the side parts is at least partially positioned at a cutout so that each of the side parts is inclined downward toward the inside. The cutout is formed by cutting off an edge part of a placement surface that is positioned on the lower processing section side.

A carbon nanotube sheet structure includes: a carbon nanotube sheet; a first base material including a first base material surface facing the carbon nanotube sheet; and a first spacer providing a gap between the carbon nanotube sheet and the first base material. A first base material surface of the first base material includes a first region on which the first spacer is provided and a second region on which the first spacer is not provided. The first base material is spaced apart from the carbon nanotube sheet at the second region on the first base material surface.
