The objective of this proposal is to demonstrate the feasibility of producing exchange-coupled magnets with a mixture of Sm2Fe17Nx and alpha double prime-iron nitride powders as starting materials. Advanced Materials Corporation (AMC), together with Georgia Institute of Technology propose to produce these powders with the use of a fluidized bed reactor and consolidate mixtures of these powders uti ...

Optical filaments, formed by high intensity ultra-short laser pulses, provide high-intensity coherent white light in the atmosphere at great distances from the laser source. This high-intensity interrogation of the atmosphere yields backward directed emissions for detection from a sensor co-located with the laser system. This has clear advantages for remote sensing in hostile environments, or en ...

Laser Induced Breakdown Spectroscopy (LIBS) is being successfully transitioned to field applications in both close-contact (proximity) and standoff detection modes. LIBS is attractive since it can be used to detect a wide range of chemical, biological and explosive (CBE) hazardous materials. While LIBS is well suited to evaluation of complex hazards, including improvised explosive devices (IEDs) ...

The main goal of the proposed program is to develop Sm2Fe17Nx/Fe16N2 high performance bulk nanocomposite magnets with maximum energy product approaching 100 MGOe. The proposed study includes: (1) Development of Sm2Fe17Nx single-phase powder with superior magnetic properties; (2) Development of Ti-stabilized Fe16N2 nanoparticles; (3) Development of nanocrystalline composite hard magnetic materials ...

KCF Technologies will develop an energy scavenging device as a component in the ankle of a lower extremity prosthetic limb. The component will be designed and demonstrated on a C-Leg, in collaboration with Otto Bock USA. The component will capture and store energy during normal activities such as walking and running. The captured energy will automatically recharge the batteries of the C-Leg. T ...

ORBITEC proposes a parallel computational and experimental effort to understand the phenomena underlying hypergolic ignition of gelled propellants. Gelled hypergolic propellants offer many benefits to modern propulsion systems. They offer good insensitive munitions characteristics and versatile performance. However, gelled propellants typically exhibit longer ignition delays than liquid propell ...

The high strength to weight and elasticity properties of spider silk make it of significant interest for the production of advanced fibers for military and civilian applications. Plants may offer the only feasible mechanism to produce quantities of spider silk proteins sufficient to sustain large scale manufacturing of these high performance fibers. Successful implementation of bioengineered spid ...

This Phase I proposal will test a UV-B light inducible system in tobacco to produce exceptionally large amounts of protein. There are three principal components to the system: 1) a tightly regulated, UV-B inducible promoter fused to a geminivirus replication associated protein (Rep) coding region, 2) a geminivirus-derived vector that is rapidly amplified by the Rep protein to produce very high y ...

This Phase I effort identifies and analyzes a variety of antennas that can be used to mitigate standing-wave effects for pulsed and/or CW sub-millimeter-wave and THz imaging spectrometers independent of their technology (e.g. mm-wave vector network analyzers vs. fast-pulse time-domain THz systems). A close collaboration with Prof. Susan Hagness, who is an expert in computational electromagnetics a ...

Few-cycle mid-infrared lasers are highly demanded for a variety of practical applications. NP Photonics and University of Arizona propose to develop a wavelength tunable and power-scalable optical parametric laser system at 8-12 micron capable of producing collimated few-cycle pulses with pulse energy>100 microJoule. In this phase I program, we will design the whole laser system and do a feasibil ...
