We have investigated two polymeric materials for incorporating high-Z metallic elements into ablation layers. Although each method ut~lizes solution-coating techniques, the materials and the resulting structures are basically different. The first, sulfonated polystyrene, which has a metal content of up to 5 atomic percent, is easily prepared and can easily be coated from solution. The second ma...

There have been many recent advances in the use of nanostructured materials for space power applications. In particular, the use of high purity single wall nanotubes holds promise for a variety of generation and storage devices including: thin film lithium ion batteries, microelectronic proton exchange membrane (PEM) fuel cells, polymeric thin film solar cells, and thermionic power supplies is ...

Recent research and development in laser machining and laser forming processes is reviewed. In the laser machining area, striation formation and prediction, and gas jet workpiece interactions are discussed. In the laser forming area, strain rate effects, and convex forming are presented.

The programme of qualification and improvement of materials for use in a fusion power station is crucial to the introduction of fusion power into the energy market and power plant studies are used to guide the targets for materials development. It is common to mis-interpret these targets as minimum values that must be achieved for fusion power to be a viable energy source, implying that failure...

A detailed investigation on the electrical, structural and fatigue characteristics of thin film ferroelectric memory devices fabricated from potassium nitrate-phase I11 (KN03-111) was conducted at Michigan Technological University under a grant from Ramtron Corporation, Colorado Springs, Colorado. This research involved: (1) fabrication and processing of 16x16 (256 bit) capacitor type memory de...
