A sealable volume has a wall forming at least a portion of a boundary limiting the volume. The wall includes a hydrogen permeation barrier including a layer system (LS) having at least one layer. The layer system includes at least one hydrogen barrier layer (HPBL) of an at least ternary oxide. Preferably, the oxide is substantially composed of Al, Cr and O and the hydrogen barrier layer (HPBL) is deposited using physical vapor deposition, in particular cathodic arc evaporation. Preferably, the layer system includes at least one of: an adhesion layer (AdhL), a hydrogen storage layer (HStL), a protective layer (ProtL), in particular a thermal barrier layer (ThBL), a diffusion barrier layer (DBL), an oxidation barrier layer (OxBL), a chemical barrier layer (ChBL), a wear resistance layer (WRL). Excellent hydrogen permeation barrier properties can be achieved, and the layer system can be tailored as required by an envisaged application.

An ice pack comprises a plastic sac with an external surface, the plastic sac forming an interior chamber, a substance within the interior chamber capable of absorbing thermal energy, and a coating, which contains one or more antimicrobial agents, on the external surface. The substance can comprise water, including polymer beads mixed with the water. The one or more antimicrobial agents can include a quaternary ammonium ion or salt thereof, such as a silane quaternary ammonium ion or salt thereof. The silane quaternary ammonium ion or salt thereof can be 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium ion, 3-(trimethoxysilyl)propyldimethyloctadecyl ammonium chloride, 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium ion, or 3-(trihydroxysilyl)propyldimethyloctadecyl ammonium chloride. Instead of an ice pack, the apparatus comprising the coating containing one or more antimicrobial agents can be an object that is used around injured people and/or perishable items such as heating pads, coolers, and ice pack carriers.
