72323B03-I The exploration of certain regimes of high energy physics will require the development of photocathodes with emitted electron spin-polarizations above 90%. Emitted electron spin-polarizations approaching 90% have been achieved, but at the expense of quantum yield. Because natural diffusion spatial spread disfavors complete transport to the emitting surface, this project will deve ...

72212-The uniform dispersion of nanoceramic filler particles within a polymer matrix, for producing high quality polymer/ceramic nanocomposites, is a very time-and energy-intensive process. The development of efficient methods for uniformly dispersing nanoceramic inclusions, which are well-adhered to the polymer throughout the polymer matrix, and for fabricating parts from such composites at low ...

Atmospheric pressure non-equilibrium plasma sources are being actively developed for a variety of industrial and military applications. Many of these applications employ ultraviolet (UV) radiation or active species (radicals) generated by the plasma. Theefficiency of plasma sources depends on the energy distribution of electrons which are mainly responsible for the production of radicals and excit ...

Idealized analysis has shown that, for the same propellant supply pressure, higher performance can be obtained in a constant-volume combustion device than the traditional constant pressure rocket. CFDRC proposes an effort consisting of multiple levels ofanalysis, followed by design and testing of a rocket engine prototype that will substantiate this claim. Recent relevant experience in advanced ...

Low-power Hall thrusters offer potentially important advantages for certain military applications but issues of lifetime and efficiency degradation at lower powers are issues hindering its utilization. A factor impacting efficiency is that thestate-of-the-art techniques for electron generation used for neutralization (such as hollow cathodes operating on the same propellant as the thruster) do no ...

This STTR project develops self-powered PZT sensor/actuators, MEMS temperature sensors and data transmitters, chip-sized mechanical impedance analyzers, and data processing procedures and integrates them into a self-contained structural health-monitoringpackage for wireless inspection of aerospace-weapons systems.The opportunity:Legacy system maintenance, the development of relatively disposable a ...

This proposal is for the design and development of a challenging, adaptable, and extendible A/I system for use in state-of-the-art computer-based wargames. The development will result in a 3rd generation computer wargame based on modern air power conflictand the ability to apply the technology developed for this project in other wargames ranging from tactical ground-based warfare to naval conflic ...

The purpose of this proposal is the research and development of low power (about 100 W) close-drift thruster with improved magnetic field. The patented design of the magnetic field makes possible to dramatically reduce the permissible size of aconventional stationary plasma thruster (SPT) that is limited by magnetic saturation of the inner magnetic path. The thruster with our improved magnetic f ...

Knowledge Analysis Technologies (K-A-T) and Virginia Polytechnic Institute and State University (Virginia Tech) will partner to fulfill this Research and Development effort. We propose an unprecedented suite of Usability Engineering software tools to bebuilt upon the conceptual foundation of Virginia Tech's User Action Framework (UAF). We will use K-A-T's proprietary Latent Semantic Analysis (LS ...

70848T02-II Fuel oil is an important part of the energy supply mix for commercial and large residential buildings, but the development of low emission, high performance burners has received little attention. Recent advances in recirculating burner development with low pressure air atomization provide an opportunity to introduce such improved systems to the market. This project will develop a ...
