Abstract:Blood Irradiators typically contain 2,000 to 7,000 curies of Cesium-137, which is a highly dangerous radioactive substance. The National Research Council has identified as a high priority the replacement of such sources with alternative technologies in order to prevent them from falling into the… more
Abstract:To improve public security and prevent the diversion of radioactive material for Radiation Dispersion Devices (or so-called dirty bombs), The US government is planning to dramatically reduce the amount of radioactive material in use. Ir-192 is the most common isotope used for radiography and poses a… more
Abstract:In X-ray Free Electron Lasers (FEL) the use of ultra-compressed beam bunches often results in a residual chirp left in the beam from the compression stages, which can be detrimental to the FEL performance. The problem is particularly acute in the next generation X-ray FELs which will be using… more
Abstract:A major problem with nuclear fission reactors is the welding of components of dissimilar metals, where the filler is usually of an additional metal alloy that is not necessarily the same as the two parts to be joined. Welding of metals will often have a heat affected zone (HAZ) and a thermo-… more
Abstract:Numerous navigation bands are currently available in addition to L1 and L2. Receivers that receive and process multiple bands are the future standard for high precision navigation, jamming resistance and spoofing mitigation. To this end, Nu-Trek"s program will deliver a multi-band signal… more
Abstract:Within the radio spectrum between 80 MHz and 3 GHz there are many signals that can augment and substitute for GPS navigation. However, current military user equipment is incapable of receiving or processing these signals. This precludes the use of many signals that are already available, plus those… more
Abstract:The proposed work seeks to demonstrate real-time monitoring of broadcast news streams to support a tactical operations center (TOC). Automatically detected essential elements of information (EEI) can be augmented with additional big data streams (news archives and social media) for relevant… more
Abstract:Remarkable advances in the emerging field of Ultrafast Electron Microscopy (UEM) have permitted atomic- resolution imaging and diffraction studies of dynamic processes with a temporal resolution measured in femtoseconds. However, limitations with femtosecond electron sources in brightness and pulse… more
Abstract:Lygos is developing new technologies for the production of high-value chemicals from renewable resources, including sugars derived from non-food biomass. The resulting technology could enable increased domestic production of chemicals near exclusively produced abroad today.
Abstract:Throughout our modern world, most of the global population has evolved a heavy reliance on computing and networks for almost all essential components of our lives. Unfortunately the threats to the information we maintain on our systems and networks are ever growing and the risks to our personal… more
Abstract:LaunchPoint Technologies proposes to adapt their patented electromagnetic valve actuator (EVA) to the C12 engine in the MTVR cargo vehicle. The actuator will allow the implementation of variable valve timing and cylinder deactivation functionality on the engine, which will result in increased engine… more
Abstract:The exploration of the structure, composition and bonding states at the nanoscale are key to the understanding of advanced materials. Transmission electron microscopes have been widely used to study materials under high spatial resolution, and when equipped with electron energy-loss spectrometers,… more
Abstract:For this SBIR project, Strategic Operations, Inc, and our subcontractor, VCOM-3D, Inc, propose to develop a Blended Reality Medical Training System (BRMTS) for humeral head intraosseus (IO) infusion. A Hyper-Realistic hands-on training manikin and Virtual Instruction System (VIS) will be integrated… more
Abstract:Maintaining warship effectiveness requires uninterrupted electrical power. Currently fielded Uninterruptible Power Supplies (UPSs) rely on lead-acid batteries to store energy and deliver power during primary power system outages. Lead-acid batteries are affordable and robust, but require regular… more
Abstract:In this abstract the development of vertical power transistors utilizing bulk GaN substrates with breakdown voltages of 1200V or higher, normally-off operation, and a drain current rating of 100A is proposed. These devices will feature vertical current flow, avalanche ruggedness, and a wide… more
Abstract:Networked applications work very badly when delay variation (queuing delay) gets large but evidence shows that current queuing delays are barely tolerable and rapidly increasing. There are a plethora of commercial, home-rolled, open source, and university created tools, but none are capable of… more
Abstract:ABSTRACT: Corrosion damage in hidden and/or hard to access locations within aircraft structures and components can be difficult to detect and even more difficult to repair. The Air Force is seeking innovative technologies for dimensionally restoring aircraft aluminum components damaged by corrosion… more
Abstract:The NAVAIR Fleet Readiness Centers (FRC) have a critical need to repair high-value assets on NAVAIR aircraft. Due to lack of off-the-shelf OEM replacement parts, these operational centers are experiencing service challenges to meet the Fleet demand. The FRCs do not currently have a technically… more
Abstract:The US Department of Energy (DOE)s networking cyber infrastructures are experiencing a massive explo- sion of data volumes because of emerging e-science applications to support high-energy physics, astrophysics, genomics, climate modeling, large-scale science collaborations, etc. The same is… more
Abstract:3um fiber laser sources suffer from limitations in the fiber, such as high loss. Fluoride fiber has been utilized as a solution for this problem, but this suffers from a low damage threshold among other issues. SA Photonics in collaboration with the LLNL Fiber Laser Group has proposed a hybrid… more
Abstract:In what follows, we propose a rather unique way to both design and construct new and certifiable composite material NDI standard calibration blocks that can be used by Air Force NDI technicians to both calibrate their existing NDI equipment and also qualify new and innovative NDI equipment for use… more
Abstract:Liquid fuel produced from dried plant material (i.e. lignocellulosic biomass such as wood chips, straw, switchgrass, and corn stover) is nearly cost competitive with corn ethanol. Lignocellulosic biomass is the most abundant, readily available, and renewable material on Earth to produce biofuels.… more
Abstract:The DOE Sunshot initiative aims at reducing the installed cost of solar energy systems by about 75% and predicts that this will drive widespread, large-scale adoption of this renewable energy technology and restore U.S. leadership in the global clean energy race. Conventional solar technologies are… more
Abstract:The objective of this project is to develop improved simulation and modeling codes for diffractive optics based on Rigorous Coupled-Wave (RCW) theory.

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.
