Award Data

Infrared (IR) windows operating in the environment experienced by endo-atmospheric interceptors are limited in performance by the high heat fluxes, temperatures, and pressures characteristic of these environments. Window temperature can exceed 900 C from exposure to the high heat fluxes and temperatures associated with hypersonic flight. Existing materials are limited by poor mechanical and optica ...

Modern Model-Based Enterprise / Engineering (MBE) systems rely on freeform surfaces built as complex combinations of geometric primitives to define engineered objects. Unfortunately, the intersection of freeform surfaces in MBE applications results in highly approximated solutions, degrading models that cost billions annually by US industry to fix. Current technology limits the abilities of users ...

Industrial facilities, manufacturing plants, and electric power plants that burn fossil fuels exhaust the combustion products to atmosphere through their smokestacks. Stack pollutant emissions are quantified using manual testing methods developed in the 1960s, which are prone to error if non-axial flow exists in a stack.Recently, NIST has been working on an improved technique of performing 3D flow ...

Phase I has proven that the current setup achieves better than 8mm spatial resolution for 2.2MeV prompt gammas. However, 1mm spatial resolution presents a significant challenge for the current setup due in part to limited timing resolution and count rate. A new analog ASIC will be developed to replace the current analog ASIC that will have better timing resolution and deliver higher count rates. I ...

In this Phase I SBIR proposal, SandBox Semiconductor™ proposes to develop an Advanced Manufacturing and Material Measurements software tool called Weave ™ for accelerating and automating SEM image analysis for the semiconductor industry. During the development of a new manufacturing process line for a semiconductor device, tens of thousands of scanning electron microscopy (SEM) images are take ...

To evaluate the technical feasibility of prompt gamma neutron activation (PGAA) as an alternative to a set of standard destructive tests of concrete petrography including aggregate type, water/cement ratio, aggregate/binder ratio, density, chloride content and chloride bulk diffusion constant; and to determine the specifications for the design of a dedicated commercial laboratory-based PGAA facili ...

This project will develop a new scientific instrument optimized for the advanced characterization of near-infrared fluorescent nanoparticles that can exist as left- or right-handed structures (enantiomers). Single-walled carbon nanotubes (SWCNTs) are the leading current example of such nanomaterials. Applied NanoFluorescence, LLC (ANF) proposes a novel multi-mode chiroptical spectrometer that can ...

In order to address various issues relating to digital element integration and execution for large-scale end-to-end capability evaluation of the Ballistic Missile Defense System (BMDS), Knowledge Based Systems, Inc. (KBSI) proposes to conduct research and development leading to the Integration, Verification &Validation for E2E Capability Evaluation for BMDS (INVICTUS) framework and supporting disc ...

Explosions and high-velocity impacts can create strain rates up to 106 s-1 in carbon-carbon composites (CCC). To simulate these events, first-principles codes require material models that are valid at these loading rates. Currently, the amount of test data, material models and material constants for this strain rate range is extremely limited, and an innovative and cost-effective laboratory test p ...

Intercontinental Ballistic Missiles (ICBMs) fired at the United States can be destroyed during their midcourse coast phase by an exo-atmospheric neutral beam of high velocity particles. Lynntech will determine the feasibility of modifying a TRL 5 magnetoplasma engine into a neutral beam emitter. Modification of the magnetic coil geometry and strength will be investigated to focus, collimate, and s ...
