Gradient Technology in conjunction with Professor M. Hillmyer of the Department of Chemistry at the University of Minnesota proposed to develop advanced technology to recover and convert the explosive and urethane binder found in plastic bonded explosives. This technology provides a unique reclamation, recovery, and reuse opportunity for dramatically reducing the disposal cost of technology munit ...

The feasibility of chemical beam epitaxy to grow ultrahigh quality GaN thin films will be developed. This process will allow the growth of GaN on high thermal conductivity substrates and enable the fabrication of precision superlattice structures. GaN will be grown using Ga effusion cells and ammonia-in an ultrahigh vacuum environment. This growth rate will be in the 1 micron per hour range at tem ...

Current off-the-shelf Windows-based software/hardware data acquisition and control (DAC) systems are relatively slow, inflexible, and incapable of driving high speed, multi-channel systems. The proposed product will advance this technology through the development of an innovative, Windows-based Graphic User Interface (GUI) and required PC-resident module interfaced with a VXI chassis containing s ...

The Theseus Logic/SUNY-Stony Brook team is proposing to develop, demonstrate and commercialize Rapid Single Flux Quantum (RSFQ) circuit designed using NULL Convention Logic (NCL). Phase I of this program will demonstrate, by simulation and modeling, the feasibility of implementing logic gate structures in RSFQ technology which can exploi the effective delay insensitivity of NCL. In Phase II the te ...

Time Domain Corporation proposes novel devices for achieving second harmonic generation in Laser Systems. The result will be a micro-size, layered, periodic, Semiconductor structure or a fiber Bragg grating that will perform several orders of magnitude better than devices in use today. Most second harmonic crystals that are currently used are of millimeter=size or greater. The simple design of ...

The objective of this research effort is to design a mobile robotic platform, and the related operator interfaces required for remote operation, which enhance a soldier's abilities to accomplish mission goals. This system will be modular in design, scaleable, low cost and rugged. The size and weight of these platforms will range form a meter long and 200 pounds, to a few centimeters long and abo ...

Higher efficiency solar cells are needed to reduce solar-array mass, volume, and cost. In this project we propose to develop: (i) a concept of the novel quantum dot superlattice (QDS) solar cells, which are estimated to be more efficient and radiation tolerant than conventional multi-junction solar cells, (ii) new computational tools for the quantum-dot nanostructure optimization for the specific ...

Morphing technology enables aerospace vehicles to achieve a broader range of operational modes. Computational aeroelastic and design analysis tools of these vehicles must be able to handle arbitrarily large deformations and shape changes. Innovative Volume of Solid technology is proposed to cast structure/body-dynamics equations in an Eulerian reference frame, preserving the order of accuracy of ...

A number of modern technologies utilize unique properties of highly non-equilibrium plasmas produced by electric discharges in molecular gases. Electron kinetics and vibrationally excited molecules define key chemical reactions in these plasmas. The goal of this project is to utilize the non-local nature of electron kinetics to improve the performance of various plasma devices under pulsed power c ...

Static stability is a major challenge for modern augmentors that feature close-coupled fuel injection/flameholders operating at low pressures and high inlet velocities, inlet temperatures and vitiation levels. Reduced dilatation and baroclinic vorticity effects at augmentor conditions cause large scale von Karman vortices to dominate the blowout event, in contrast to conventional bluffbody shear l ...
