Applied Quantum Technologies proposes the development of a snapshot Raman spectral imager for chemical imaging applications with a 1-5 meter standoff. Standoff chemical imaging methods are typically point-based, making scan times impractical for situations where a wide area needs to be surveyed. The high spectral resolution needed to take advantage of the specificity of Raman spectroscopy limits t ...

ABSTRACT: Providing electrical power for long duration hypersonic flight is a technology that is required to bring about this revolutionary mode of transport. Whether for weapons delivery or for space access, the long duration missions anticipated require a novel approach to the generation of electrical power during flight. Scramjets contain no rotating shafts from which typical generators or mec ...

ABSTRACT: The potential of scramjet engines for use by the U.S. military would revolutionize countermeasures enabling rapid responses to global hot spots. The scramjet traveling at hypersonic speed cannot use rotary power typically employed at sub-Mach velocities, while auxiliary power units and batteries add weight, volume, and system complexity. Thus, alternative power sources are sought to ai ...

This STTR phase II proposal addresses AFOSR's task to: "Develop seamless, easy to use, efficient code to calculate electronic wave functions and potential energy surfaces of molecules and predict kinetic rate constants for reactions a priori." This is a long-unsolved problem, fundamental to chemistry, where quantum chemical methods must be extremely accurate to yield reliable rate constants. Yet u ...

The conceptual design of a novel, hypersonic electromagnetic launch system has been developed. Phase-1 assumed a 100-kg projectile leaving the launcher at 7,000 m/sec. The projectile is propelled and levitated by electromagnetic forces inside a tube filled with low pressure helium. A controlled acceleration profile, fully adjustable to the requirements of various missions, is used to reach 5000 ge ...

The development of tractable mathematical models of gradient-frequency nonlinear resonator networks is critical to advanced computer applications that require faithful computer simulation of human attention and/or perception. Conventional linear resonator models are computationally and analytically tractable, however tractability is achieved at the expense of capturing many significant features of ...

An innovative methodology, based on mechanistic models, will be developed for prediction of long-term (25+ years) durability of composites for the US Army's emerging facilities in different climatic zones. Accelerated testing simulating the Army's composites applications in various constructions and fields will validate it. Phase I developed the basic predictive tool using the Arrehenius principle ...

Kyma Technologies will team with North Carolina State University to develop growth techniques using the hydride vapor phase epitaxy technique to fabricate large area non-polar GaN substrates. Using high quality non-polar seed crystals developed during the Phase I effort, the HVPE growth process will be optimized to increase the GaN crystal size and result in large area substrates. Kyma will perfor ...

Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

Cermet, Inc in collaboration with Georgia Institute of Technology proposes to develop spin Light Emitting Diode (LED) in a 24 month Phase II program. The spin LED is a simple yet powerful spintronic device that produces circularly polarized light and is a potent tool to quantify the spin injection efficiency and spin polarization efficiency.
