The Elite: A high speed, low-cost general aviation aircraft for Aeroworld

The Elite is a six passenger, general aviation aircraft targeted at the upper middle class private pilot. The Elite is a low wing, conventional monoplane utilizing rudder, ailerons, and a stabilator. The Elite will create a new class of aircraft in Aeroworld. This class of aircraft will demonstrate a substantial improvement in cruise speed over the current existing commercial fleet of aircraft in Aeroworld. This new class will be capable of servicing all existing airstrips in Aeroworld, including rough and short airways. The drivers of this design were aesthetics, a high cruise speed, and take-off distance

Synthesis of the positron-emitting radiotracer [18F]-2-fluoro-2-deoxy-d-glucose from resin-bound perfluoroalkylsulfonates

A new approach to the synthesis of 2-fluoro-2-deoxy-D-glucose (FDG, [19/18F]- 3) is described, which employs supported perfluoroalkylsulfonate precursors 33–36, where the support consists of insoluble polystyrene resin beads. Treatment of these resins with [19F]fluoride ion afforded protected FDG [19F]- 18 as the major product, and the identities of the main byproducts were determined. Acidic removal of the acetal protecting groups from [19F]- 18 was shown to produce [19F]FDG. The method has been applied to the efficient radiosynthesis of the imaging agent [18F]FDG, and was shown to produce the radiochemical tracer in good radiochemical yield (average 73%, decay corrected)
