Selective Clay Placement Within a Silicate Clay-Epoxy-Blend Nanocomposite

The resulting toughened epoxies and composites are used for commercial and military aircraft, and marine applications. John H. Glenn Research Center, Cleveland, Ohio The dispersion of a layered silicate into an epoxy matrix often increases the material strength and stiffness, but reduces resin toughness. This innovation is a method to selectively place organically modified clay within specific regions of an epoxy blend, where the clay provides maximum benefit to the material performance. By this process, the material yield stress was observed to increase by 40 to 100%, depending on the blend composition. The toughness of the material, as defined by the area under the stress-strain curve, was observed to increase or remain unchanged.

Zero-G Condensing Heat Exchanger with Integral Disinfection

The proposed concept promises to improve the life support environment for astronauts. John H. Glenn Research Center, Cleveland, Ohio A concept for a unique zero-g condensing heat exchanger that has an integral ozone-generating capacity has been conceived. This design will contribute to the control of metabolic water vapor in the air, and also provide disinfection of the resultant condensate, and the disinfection of the air stream that flows through the condensing heat exchanger.
