The present invention relates to a method and apparatus for providing and/or receiving audible sound. In particular, the invention relates to apparatus, such as a micro speaker, which includes an active region which comprises a particulate adsorbent material comprising i) microporous organic polymer (MOP) material, and/or ii) metal organic framework (MOF) material treated with a hydrophobic coating or a membrane. The particulate adsorbent material is either in the form of loose or semi-loose granules, or it is supported by or impregnated into a woven, knitted or non-woven felt material. The apparatus of the present invention is suitable for use in an electronic device, for example a mobile or portable electronic device, to provide improved audible sound.

The invention generally relates to a process for purifying a hydrogen gas for use in a fuel cell. The process involves taking a hydrogen feed stream from a high-pressure tank and passing it through a purifier comprising an adsorbent to provide a purified hydrogen stream which is sent to a fuel cell. A particular adsorbent which can be used is a metal-organic framework composition. The adsorbent can be housed in a device such as a canister or cartridge having an inlet and outlet port.

The invention is directed to a nanostructured composite material comprising a mixture of at least one metal particle such as iron and a carbon material from biomass such as D-glucose, D-glucosamine hydrochloride or α-cyclodextrin. The invention is also directed to a composition comprising the composite material comprising the composite material and an inorganic salt, and a method for synthesizing the composite material comprising immersing the carbon material into a solution of metal ions, drying the impregnated carbon particle and subjecting the impregnated carbon particle to a carbothermal reduction process. The nanostructured composite material is useful as an oxygen scavenging layer in a multi-layer film which comprises the oxygen scavenging layer and an oxygen barrier layer that retards the permeation of oxygen from an external environment.
