Abstract: A method and system for diamagnetic manipulation of an object in a surrounding medium in a low gravity environment is provided. The system can be used in various applications such as containerless materials processing, protein crystal growth, and particulate filtering. If the application requires directional manipulation of the object, at least one magnet or electromagnet is required. The object is repulsed by the magnet if the object is more strongly diamagnetic than the surrounding medium. If the object is less diamagnetic than the surrounding medium, however, then the object is effectively attracted to the magnet. For an application that requires suspension of the object, two oppositely polarized magnets are used to generate an appropriate magnetic field gradient to suspend the object in a location where opposing field vectors generated by the two magnets cancel each other out, producing a net field strength of zero.

Abstract: The morphology of multidimensional, thermally stable oligomers is combined with the inclusion of charge carrier linkages within the polymer arms to produce thermally stable advanced composites from cured oligomers that are conductive or semiconductive if suitably doped.

Abstract: The morphology of multidimensional oligomers is combined with the inclusion of charge carrier linkages within the oligomer arms to produce oligomers that are useful for preparing conductive or semiconductive composites, if suitably doped. The Schiff base linkages are prepared by the condensation of aldehydes and amines. The oligomers can be blended, and either the oligomers or their blends can be prepregged.

Abstract: Filled fluorosilicone and filled fluorophosphazene composite films and unfilled fluorosilicone, fluorophosphazene, or copolymers provide atomic oxygen resistance to protect surfaces on spacecraft in low earth orbit. The preferred composite films are generally made by polymerizing suitable precursors on the exposed surfaces, the filler being mixed with the polymer precursors prior to curing. Second surface mirrors can be protected with these films while the flexibility of the mirror is retained.
