Abstract: A method of producing porous complex oxides includes the steps of providing a mixture of a) precursor elements suitable to produce the complex oxide; or b) one or more precursor elements suitable to produce particles of the complex oxide and one or more metal oxide particles; and c) a particulate carbon-containing pore-forming material selected to provide pore sizes in the range of approximately 7 nm to 250 nm, and treating the mixture to (i) form the porous complex oxide in which two or more of the precursor elements from (a) above or one or more of the precursor elements and one or more of the metals in the metal oxide particles from (b) above are incorporated into a phase of the complex metal oxide and the complex metal oxide has grain sizes in the range of about 1 nm to 150 nm; and (ii) remove the pore-forming material under conditions such that the porous structure and composition of the complex oxide is substantially preserved. The method may be used to produce non-refractory metal oxides as well.

Abstract: A differential gear assembly which is suitable for providing a power off-take from a gas turbine engine, comprises first and second power input gears which drive a plurality of idler gears rotatably mounted on a common cage structure. The idler gears are grouped in meshing pairs so that one idler gear of each pair is additionally in meshing engagement with one of the power input gears and the other idler gear of each pair is additionally in meshing engagement with the other of the power input gears. Together the first and second power input gears drive the common cage structure at the mean speed of the power input gears and the common cage structure in turn drives a single power output shaft.

Abstract: A method for producing complex metal oxide having nano-sized grains that includes the steps of forming a mixture containing at least one metal cation dissolved in a solution and particulate material containing at least one further metal in the form of metal(s) or metal compound(s) and treating the mixture to form the complex metal oxide having nano-sized grains. The at least one further metal from the particulate material becomes incorporated into the complex metal oxide.
