Single-walled carbon nanotubes (SWCNTs) have unique material properties making them very attractive for use in a variety of electronic applications. However, as-grown SWCNTs contain a mixture of tubes with heterogeneous optical and electronic properties. The chiral species must be separated in order to maximize the desired properties. To date, no large scale separation process has been accomplishe ...

We will develop technology, termed a Ruggedized Wind Measurement System (RWMS), to measure directly extreme winds with high space and time resolution, focusing on the winds that occur beneath hurricanes at land fall. This development effort will include design, fabrication of two prototype RWMS units, and a series of proof-of-concept demonstrations in strong mountain-induced downslope and severe t ...

In the conduction of benchmark combustion experiments, a fuel spray nozzle that produces a steady-well-defined spray is needed. This fuel spray, of known properties, is a boundary condition for the atomization, mixing, and combustion which results throughout the combustor volume. Present spray nozzles use fluid turbulence, which is chaotic, to drive the spray formation. Because the turbulence ampl ...

Finish machining of structural ceramics can produce residual stresses, and subsurface defects (SSD) acting as stress concentrators, in the near-surface material. Residual stresses and SSD produced by machining affect the mechanical properties of ceramic components. In this context, it is essential that the residual stresses be properly quantified in ceramics, in order to establish suitable machini ...

While much of the data involved in product and order definition has been captured in standard electronic structures such as IGES and EDI, material and process specifications are still handled as amorphous, paper-based documents. The use of manual, text-based specifications is an extremely labor-intensive and time-consuming process. Specifications are an integral part of the product and order defin ...

This proposal describes a new research program to be established at the small business Still Sciences, LLC, in collaboration with Department of Physics of Oklahoma State University. The overall goal is to develop and commercialize an all-optical dosimetry system for industrial radiation processing based on a novel Pulsed Optically Stimulated Luminescence readout technique and a new Al2O3 material ...

A program is proposed to demonstrate the feasibility of developing a general computational fluid dynamics (CFD) method for predicting turbulent, multi-phase mixing and reacting fluid/particle dynamics for three-dimensional spray combustion systems. The method allows coupled flow, chemistry and polydisperse aerosol behavior to be calculated efficiently in a Eulerian reference frame. Dispersed dropl ...

In the Phase I effort, in order to build a cost-effective multicomputer, we will refine our proposed system-level design, specify the appropriate combination components which meet the desired goals, procure and assemble the hardware components and operating system, install the other systems software with which to perform parallel programming, and demonstrate the multicomputer. The key concept beh ...
