The U.S.… more
Abstract:The proposed work will result in a method for production of dense, hard, tough, strong tungten carbide (WC) ceramic material for ultimate use as the penetrating core in armor piercing projectiles. Focus is on the development and feasibility of a titanium silicon carbide (Ti3SiC2) based matrix as a… more
Abstract:Transportable energy storage systems are emerging products for grid-tied applications. High voltage pulse power systems are planned for assembly in standard shipping containers to allow for easy transportability. Unfortunately, the current capabilities of these systems are considered inadequate… more
Abstract:Thermally stable machine gun barrels that exceed current barrel life, reduce dispersion, and allow higher or longer sustained rates of fire, require erosion-resistant, high temperature materials and techniques to integrate them. The goal of this program is to eliminate the need to carry extra… more
Abstract:DESCRIPTION (provided by applicant): According to the National Institutes of Health, there are more than 80 million people in the US who suffer from a potentially sight-threatening disease. Doctors see seven to eight million new cases of eye disease annually. More than two million Americans age 50… more
Abstract:Aerosol research remains a priority area and requires strong efforts to resolve the very complex processes that occur in the atmosphere. To understand aerosol formation and their implications on climate the study of precursors provides very valuable information. Ammonia is one of the most… more
Abstract:Aircraft On-Board Oxygen Generating System (OBOGS) selectively filters compressed air from the aircraft's engine to remove nitrogen and other gaseous contaminants to provide the aircrew with an oxygen enriched breathing gas. During shipboard operations, Navy aircraft are particularly vulnerable… more
Abstract:The successful results of the Phase I work will be utilized by implementing an optimized ultra-short pulse Optical Parametric Chirped Pulse Amplifier at an eye safer Short Wave InfraRed (SWIR) wavelength. The system will be designed with a goal of 1 kHz repetition rate and will ultimately reach a… more
Abstract:To address the Army"s Phase-II requirements for a low-cost chaos-based radar demonstrator, TechFlow and its research partners- the University of New Mexico and Forza Silicon Corp., will implement and test a prototype E-band chaos radar system incorporating a coherent receiver. In Phase I, the… more
Abstract:To address PEO Ground Systems requirements for a low-cost system that can determine and display convoy vehicle spacing in low visibility conditions, TechFlow will adapt the capabilities of its innovative millimeter-wave coherent chaotic radar technology, currently being developed under an… more
Abstract:ABSTRACT: Mission planning, briefing, and debriefing in live virtual constructive (LVC) exercises has become a distributed operation. These exercises produce mission data that must be disseminated to all local and remote players for instructional and research purposes. The warfighter"s… more
Abstract:ABSTRACT: High-power electromagnetic (HPEM) interference can disrupt normal operation of aircraft electronic systems and cause mission abort or even endanger the crew. HPEM energy couples into these systems mostly through the conductors in the power distribution network (PDN) of packaged chipsets.… 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.
