Abstract: A method of manufacturing a hydrogen fuel cell hose and component parts is disclosed herein, including blending a formaldehyde-based, semi-crystalline engineering thermoplastic with graphene, wherein the graphene has a thickness of less than about 3.2 nm, a particle size of between about 50 nm and about 10 ?m, and contains greater than about 95% carbon, exfoliating the graphene into plates, wherein the graphene plates having substantially no carboxylic acid, alcohols, ketones, aldehydes, or hydroxyl groups on the graphene plate surface or graphene plate edges, and aligning the graphene plates into perpendicular alignment, such that the graphene plates provide a barrier to migration of oxygen, nitrogen, moisture, or water vapor molecules.

Abstract: A presentation display case for storing, displaying or preserving paper currency or valued memorabilia. The case is formed as a transparent, durable display case for sealing and preserving paper currency and memorabilia e.g. items that will be of monetary value when redeemed which can be displayed in trophy fashion in a casing that can stand on its base without the need for a stand.
