X-ray fluorescence spectroscopy is a widely used and extremely sensitive analytical technique for qualitative as well as quantitative chemical analysis. Superconducting Transition Edge Sensor (TES) microcalorimeter detectors have now been developed that achieve an energy resolution of 2 eV (full width at half maximum) for 1.5 keV X-rays, which is sufficient to enable the measurement of the small s ...

ABSTRACT: The proposed Phase I Small Business Technology Transition (STTR) program will develop and demonstrate a thermally conductive structural two-dimensional (2D) graphite fiber reinforced hybrid matrix composite material with a through-thickness thermal conductivity of at least 20 W/m & #8729;K. This novel structural prepreg material will be developed through engineering of an optimal fiber ...

ABSTRACT: RNET and The Ohio State University propose to use algorithmic modifications and multi-level parallelization techniques and tools to improve the scalability of the CFD/CSD codes relevant to the DoD/AF (e.g., CREATE/Kestrel). The linear system solver is expected to be a primary bottleneck in aero-line/aero-elastic CFD and CSD codes. RNET and its subcontractors will explore effectiv ...

ABSTRACT: The proposed Phase I Small Business Technology Transition (STTR) program will develop and demonstrate a Hybrid Graphitic Foam with tailored surface chemistry for optimal heat transfer characteristics for high heat flux, high thermal energy storage applications. Such a material system, in combination with an infused Phase Change Material (PCM) or Metal Hydride (MH) will exhibit several ...

ABSTRACT: Multidimensional simulation of plasmas will be critical to the design of high voltage and high energy density devices over coming decades. Individual fluid simulation codes are presently limited to one or perhaps two of three plasma models: the higher densities and longer time scales of magnetohydrodynamics (MHD), the lower densities and shorter time scales of extended MHD (XMHD), and ...

ABSTRACT: We propose to develop and validate a strongly-coupled non-equilibrium plasma simulation model. Strongly coupled plasmas occur in a wide range of physical situations impacting a wide range of research and development areas connected to Air Force technology. The simulation model proposed here is based on the particle-in-cell (PIC) methodology, which has recently been validated by the pro ...

ABSTRACT: Phosphor materials are currently being utilized in a wide variety of applications. The requirements for phosphors have become more and more stringent with smaller and smaller particles being required. In the Phase I program UES Inc in collaboration with Penn State University proposes to develop a novel approach for high rate production of high efficiency IR to IR up-converting nanoparti ...

ABSTRACT: TechFlow Scientific, a division of TechFlow Inc., along with its teaming partner, the University of New Mexico, is pleased to propose a three-phased research and development effort for the design, development, fabrication, and testing of miniaturized functional cellular elements that can be incorporated into an ensemble based mesoscopic framework. The TechFlow team comprises leading sci ...

The research objective of the proposed work is to apply the foundational knowledge of ultrasonic bonding, metallic composites, microstructure transformation kinetics and material failure criteria to create a multi-scale simulation model for the optimization of ultrasonic additive manufacturing (UAM) of metallic composites. The ultrasonic fabrication will be represented as a superposition of multip ...

Reductions and reallocations of telemetry wireless bandwidth have prompted the need for DoD agencies to adapt to operation in more restricted and less desirable frequency spectrum. Telemetering systems must evolve to address these frequency allocation changes, while retaining operational characteristics that are vital to MDA mission success. The design and implementation of high performance transm ...
