Abstract:The United States is the world¿s second largest producer of natural gas and also the largest importer. The increasing price of natural gas, along with a decreasing domestic supply, presents an opportunity to develop low-cost replacements. Thermo-chemical production of Synthetic Natural Gas (SNG)… more
Abstract:Development efforts for hybrid Flash Ladar receivers are underway, however a common limitation is the lack of an appropriate Readout Integrated Circuit (ROIC) to amplify and condition the hybrid Flash Ladar signals. Though Flash Ladar ROICs exist for direct-detect mode and concepts are under… more
Abstract:Aerius proposes to build detectors with low dark current and a cutoff wavelength of 3.0 um, using InP-based detectors. These detectors do not suffer from the same problems conventional "extended-wavelength" detectors suffer, such as high dark current, low quantum efficiency, and limited spectral… more
Abstract:The performance of diode pumped solid state lasers (DPSSLs) is often limited by the performance of the diode laser arrays used to pump the crystal. Of the components making up the DPSSL module, the diode laser arrays consume the most power, dissipate the most waste heat per unit area and are among… more

The approach employs Aerius' Optical preamplified Pixel Array (OPPA) which consists of a 2-D array of… more
Abstract:Aerius Photonics proposes to develop fiber laser pump modules based on Vertical-Cavity Surface Emitting Laser (VCSEL) arrays which can have a manufacturing cost ten times lower than the existing Edge Emitting Laser (EEL) technology. Aerius will demonstrate and deliver high power VCSEL array modules… more
Abstract:Aerius Photonics is proposing a highly practical and effective plan to develop a scene projector that allows the polarization state of each pixel to be independently and dynamically controlled at full frame rates. The projector would utilize a single unpolarized resistor array system with a 4… more
Abstract:Passive microwave emission from a missile plume offers potential for all-weather early launch detection because of superior microwave penetration through obscuring clouds, dust, haze, and fog. The task is to estimate through simulation the plume passive microwave signature due to gas/particle… more
Abstract:With improvements in high performance military jet aircraft engines and the increase in complexity of the exhaust systems the noise produced has become problematic. Reducing these noise levels, while maintaining overall system performance, has become the driving issue in new nozzle designs. This… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project aims to develop methodology and software for highly accurate and efficient semantic video retrieval and summarization. Video Semantics will, provide personalized summaries of video content that meet users' preferences. These summaries… more
Abstract:The drumbeat for higher efficiency gas turbine engines is driving new designs capable of operating at higher temperatures and pressure ratios, in fewer stages, and with higher airfoil loads. These conditions pose a great challenge for turbomachinery designers. They must now accurately predict… more
Abstract:Ammonia has an important role in the chemistry of the atmospheric environment and air quality. Ammonia emissions are a major environmental concern, yet they remain poorly quantified. There is a need for a sensitive ammonia instrument to monitor emissions and evaluate their effects on local and… more
Abstract:Carbon dioxide is monitored worldwide at hundreds of monitoring stations. However, existing methods rely on the use of high pressure calibration gas cylinders, which are both labor intensive and expensive. Thus, there is a pressing need for an affordable, highly accurate (at least 1 part in 3000)… more
Abstract:We propose to design, construct and test a first implementation of a non-dispersive technique for the measurement of atomic absorption in the plumes of liquid rocket engines in altitude test facilities. Led by NASA Stennis Space Center (SSC), the observation of metal atom emission from liquid… more
Abstract:This Small Business Innovation Research Phase I project proposes to develop a clinical monitor for propofol (2,6-diisopropylphenol), an intravenous anesthetic drug widely used in general surgery and as a sedative agent in the intensive care unit (ICU) because of its favorable safety profile and… more
Abstract:We have built and tested an optical extinction monitor for the detection of spacecraft cabin particulates. This sensor sensitive to particle sizes ranging from a few nanometer to tens of micrometers in diameter. Designed to utilize commercial off- the-shelf components, the monitor, once calibrated,… more
Abstract:Low visibility flares offer significant advantages for nighttime protection of rotary wing vehicles. Aerodyne Research Inc (ARI) and its teaming partner ATK propose flares having nearly same intensity in IR bands of interest while having greatly reduced visibility. The Phase I program will build… more
Abstract:This Small Business Innovation Research Phase II project concerns the development of a multi-wavelength monitor that will provide rapid, real-time measurement of the average aerosol absorption coefficient in a parcel of sample air. This monitor will employ Aerodyne's patented Cavity Attenuated Phase… more
Abstract:Aerodyne Research, Inc. (ARI) and MIT are collaborating to establish the feasibility of fully characterizing the complex chemistry of JP-10 high temperature decomposition, in the presence of oxygen, using a novel automatic reaction mechanism generation tool (RMG) developed at MIT. JP-10 is a very… more
Abstract:The characterization of aircraft particulate matter (PM) emissions has benefited greatly by the Aerosol Mass Spectrometer (AMS) by providing size resolved compositional information. AMS data have been critical to much of our understanding of aircraft PM emissions, but it has limited utility in… more
Abstract:Although aerosol particles have important impacts on visibility, acid deposition, climate, and human health, large uncertainties remain in quantifying their chemical composition and atmospheric transformations. Particularly lacking are real-time, quantitative instruments for the identification,… more
Abstract:Distinguishing between photosynthetic uptake and respiratory emission of CO2 from plants is a difficult problem; yet, determining the small difference between these two parameters is crucial for determining the net ecosystem exchange of CO2 between the atmosphere and the biosphere. Carbonyl sulfide… more
Abstract:Aerosol particles have important impacts on visibility, acid deposition, climate, and human health. A large fraction of these aerosols are generated from energy-related activities. These organic aerosols can be directly emitted from combustion sources or formed through gas-phase reactions of… more
Abstract:The increase of carbon dioxide (CO2) in the Earth¿s atmosphere is the most important driver of global warming. In order to predict future carbon dioxide concentrations under various mitigation strategies, a much better quantitative understanding of the sources and sinks of atmospheric carbon… more

There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
