Abstract: A transition piece for use in a foundation of an offshore wind turbine including a tubular concrete support structure for supporting the wind turbine. The concrete support structure has a first end arranged to receive an end portion of a pile for mounting the transition piece on the pile and a second end distal from the first end for supporting the wind turbine. The transition piece may form part of the foundation for the offshore wind turbine in which the transition piece is mounted on the end of the pile extending from the sea floor. The end of the pile on which the transition piece is mounted is below the surface of the water and the transition piece protrudes above the surface of the water such that the wind turbine may be mounted thereon.

Abstract: A method of producing a hydrogen storage material including the steps of: forming a magnesium-nickel melt having up to 50 wt % nickel; adding up to 2 wt % of a refining element to the melt under a non-oxidizing atmosphere, the refining element having an atomic radius within the range of 1-1.65 times the atomic radius of magnesium, such as at least one element selected from the group consisting of Zr, Na, K, Ba, Ca, Sr, La, Y, Yb, Rb and Cs; and solidifying the melt to produce the hydrogen storage material.

Abstract: A method of forming a hypoeutectic aluminium silicon alloy including the steps of: forming an aluminium melt including greater than zero and less than about 12 wt % silicon, adding 20-3000 ppm of a eutectic modifying element selected from the group consisting of strontium, sodium, antimony, barium, calcium, yttrium, lithium, potassium, ytterbium, europium and mischmetal; and either adding nucleant particles and/or causing nucleant particles to be formed in the melt, the nucleant particles being selected from the group of TiSix, MnCx, AlP, AlBx and CrBx wherein x is an integer of 1 or 2.
