Current techniques for the production of spherical, micron size, monodisperse metal powders such as comminution, atornization and gas phase synthesis cannot produce reactive metal powders on a large-scale while maintaining a pure surface. Coating of these highly reactive metal powders with a passivating layer requires special handling. Conventional processing techniques such as fluidized bed and ...

Conventional composite processing techniques are presently unable to fabricate Al1O3-fiber reinforced y-titanium aluminide matrix composites based on low cost, small diameter ( 5-20um) fibers. The primary problem is one of infiltration of the matrix in between the fibers without any degradation in fiber properties. Although pressure casting would be a low cost processing approach, the severe che ...

Design and fabrication of a high thermal conductivity carbon fiber/aluminum matrix composite architecture is proposed which consists of discrete segments of functional areas that can respond to complex design calling for thermal management, low-expansion, structural, and low specific weight requirements. Composites will be produced utilizing Hollow and Planar Cathode Magnetron Sputtering Processin ...

Current concepts of holographic and dye technology do not provide eye protection from lasers at unknown wavelength and in the spectral region from 400 - 900 nm. Recently it has been shown that fullerenes have excellent nonlinear optical properties and show the best limiting performance of all materials including response in the nanosecond range. This program will further investigate fullerenes ...

There is a critical need for the development of high temperature, corrosion resistant, low weight, and low cost recuperators to increase the efficiency of advanced gas turbine engines. The temperature requirements dictate the use of ceramic materials, and the material choice is silicon carbide (SiC) as a result of its high thermal shock resistance, high thermal conductivity, excellent corrosion r ...

There is an increasing need for innovative technologies that can destroy hazardous chemical wastes cost-effectively. The ideal technology needs to be non-polluting, of low capital and operating costs and capable of producing useful products from the wastes. Destructive Absorption Technology (DAT) has been demonstrated to meet two of these needs: DAT is non-polluting and can produce useful product ...

There is an increasing need for an innovative technology for low cost remediation of chemical warfare agents and chemical wastes. Existing technologies such as bioremediation are not suitable for remediating chemical warfare agents because they are toxic to biological processes. Furthermore, for chemical wastes of military and some commercial wastes such as surfactants, bioremediation is too slow ...
