Abstract:Presently the Marines use a wide range of handheld, head mounted, and weapons-mountable optical systems. These devices serve many functions; from visible and night vision imaging to target designation and ranging. Optical rangefinders employed by the Marines mostly utilize active laser sources.… more
Abstract:Threat of attack from within obscuring foliage is a very real threat to U.S. riverine craft or other marine operations close to shore. Generally, this asymmetric situation allows opposing forces to hide undetected within or behind bushes and trees until an opportune moment for attack. On the other… more
Abstract:Commercial gas sensors employ a number of different transduction mechanisms depending on the nature and reactivity of the gas and include systems based on optical, electrical and mass detection. Recent advances in gas sensor technology have provided even more sensitivity and are poised to increase… more
Abstract:Multispectral zinc sulfide (ZnS) because of its good visible and near infrared transmission as well as the 3-5 micron and, more importantly, the 8-12 micron range along with its good thermal shock resistance is one of a number of materials used as infrared windows. The window serves to protect the… more
Abstract:Nanohmics proposes to design a nanowire-based FET (NWFET) around an advanced nanolithographic imprint methodology which will lead to a scalable and economically competitive manufacturing process. The NWFET will consist of Si nanowires etched from an epitaxially deposited single crystal layer of Si,… more
Abstract:Wound-related pathogens (WRPs) are a major challenge affecting the care of injured soldiers. Infection caused by WRPs leads to morbidity and can lead to mortality if appropriate care is not administered in a timely fashion. Therefore, rapid identification of wound related bloodstream infections in… more
Abstract:Ceramics materials have great potential in a wide variety of applications but their use is often limited by the associated high cost of machining. Developing laser assisted machining (LAM) for a commercial environment will greatly mitigate these costs. Nanohmics and Dr. Y. C. Shin of Purdue… more
Abstract:Over the past fifty years, technological advancements in the microelectronics industry have been astounding. As a result of this success, today's microfabricated devices are inexpensive, can be produced in large volumes, and can be fabricated with billions of sub-100 nm logic elements as small area… more
Abstract:Nanohmics, Inc will develop a drop-in LED replacement for the M6363/3-2 reflector SC bayonet mount bulb used in these wingtip lighting assemblies. The Nanohmics LED replacement will have the same physical dimensions as well as comparable light output and angular intensity while using less electrical… more
Abstract:Production of long life, light weight, high-volumetric-energy-density, high-voltage bus capacitors, which are stable at temperatures over 250C, would enable the electrical system of an electric vehicle to operate at a higher temperature, thereby readying these systems for next-generation SiC-based… more
Abstract:The $100B thermal control market is dominated by compressed gas technology. Peltier devices are an interesting solid state alternative to standard compressor technology; however, these devices are grossly inefficient and are not capable of removing massive quantities of heat. Nonetheless, a solid… more
Abstract:Researchers have determined that lunar soil contains approximately 43% oxygen in the lunar soil oxides, which could be extracted to provide breathable oxygen for consumption by astronauts. The proposed program will develop a solar receiver for the hydrogen reduction process that uses sodium heat… more
Abstract:The DOE is investigating new technologies for high performance, low cost heat exchangers. One way to achieve this goal is to develop improved heat transfer fluids using nanotechnology. Nanofluids are metallic nanoparticles (10 -100 nm) that increase overall thermal conductivity when dispersed in… more
Abstract:Advanced Cooling Technologies, Inc. (ACT), supported by Texas A&M University (TAMU), proposes to develop a Momentum-driven Vortex Separator (MVS) technology for vapor and liquid management for the advanced vapor cycle Thermal Management Systems (TMS). The MVS developed at TAMU is a single component,… more
Abstract:Long-term Lunar and Martian systems present challenges to thermal systems, including changes in thermal load, and large changes in the thermal environment between day and night. The innovation in the program is the development of a variable conductance heat pipe (VCHP) that passively accommodates… more
Abstract:The Airborne Laser (ABL) program has significant cooling requirements that until present can only be addressed by mechanical refrigeration systems. These include cooling of the various high powered solid state lasers currently used on the ABL for tracking and ranging as well as standby cooling for… more
Abstract:This Small Business Innovative Research Phase I project will develop an innovative High Velocity Particle Consolidation system using liquid particle acceleration mechanisms for Cold Spray applications. Conventional Cold Spray uses high pressure process gas to accelerate particles to a critical… more
Abstract:As thermal management requirements aboard Navy platforms increase, conventional HVAC technology is becoming a liability in terms of mass, volume, and heat transfer capability. Future thermal demands will increase and the majority of this load will be handled by either the HVAC or chilled water… more
Abstract:Heat exchangers are often required to remove waste heat and cool vital components in industrial processes, automobiles, and commercial heating and cooling systems. The thermal efficiencies of these heat exchangers directly affect the overall energy efficiencies of these processes, and many aspects… more
Abstract:The Full Authority Digital Engine Control (FADEC) controls engine operation. It is historically mounted on the engine case to minimize the routing length of the sensor and actuator wiring. The FADEC must be maintained below 70oC, while the environment can be as hot as 170oC. The current design uses… 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.
