Abstract: A method of electrospinning fibres is disclosed. The fibres have an inner core surrounded by a porous outer shell. The method comprises co-electrospinning first and second liquids as core and shell respectively, the second liquid surrounding the first liquid in a jet issuing from a Taylor cone, wherein the first and second liquids are miscible or semi-miscible with each other, such that pore generation is driven in the shell of the fibre. The liquids may be solutions or melts. The electrical conductivity, viscosity, miscibility and other parameters of the liquids determine the structure of the produced fibres. As well as producing fibres having a porous shell there are described methods of co-electrospraying porous beads as well as core- shell vesicles having a porous shell. The methods may be used to produce hydrogen storage fibres, vesicles and beads. The methods may also be used for producing controlled drug- delivery fibres, vesicles and beads.

Abstract: Composite fibres are produced by co-electro-spinning core and shell / sheath liquids. Vesicles are produced by co-electro-spraying core and shell liquids. The core has higher electrical conductivity than the outer layer which surrounds it in a jet issuing from a Taylor cone. Porous or non-porous outer layers can be formed by using miscible or immiscible liquids. Hollow fibres can be produced by removing the core. Preferably the core comprises a pharmaceutical drug or a hydride, especially ammonia borane or an amide-hydride compound, a borohydride or a amido-borane of magnesium, lithium, sodium, aluminium, potassium, beryllium or calcium. Preferably the shell comprises a polymer, especially polystyrene, polysulphone, polyvinyl acetate (PVAc), polyimide, polybenzinmidazole, polystyrene butadiene, polyvinylidene fluoride (PVdF). The materials can be used to store hydrogen, as a wound dressing or tissue scaffolding.

Abstract: The present invention relates to a method of producing hydrogen from ammonia, and in particular a method of producing hydrogen from ammonia by reacting it with a Group I metal, particularly with sodium, for use in a fuel cell and/or in a prime mover. The method may be carried out in-situ in a vehicle. The invention also relates to an apparatus for producing hydrogen from ammonia.
