Abstract:The superior optical properties of BBO and its applicability in frequency doublers and waveguides justifies development of thin film deposition processes which can be integrated with microelectronic processing. The high damage threshold of BBO, a necessary component for device integrity, is a major… more
Abstract:We propose to demonstrate the feasibility of solar-blind, multi-spectral III-V nitride UV detectors which can meet the requirements of applications in both the military and commercial sectors (missile threat warning, UV search and track, environmental monitoring in gas turbines, and general flame… more
Abstract:Spatial light modulators (SLM's) have been identified as critical elements in many optical computing and signal processing applications. Typically these devices use expensive bulk ceramics that result in high cost and difficult device integration. Ceramic materials in the PbLaZrTiO3 (PLZT) family… more
Abstract:Phase I will develop a gas-phase process for the deposition of low dielectric constant polymers for use in integrated circuits. This process will utilize the firm's liquid delivery technology to deliver the reactants and grow films at high deposition rates. Polymerization will be induced by thermal… more
Abstract:Radiation hardened ferroelectric random access memory (FRAM) devices have potential uses in numerous military applications. Until recently, FRAMs have relied on lead zirconate titanate (PZT) as the storage material. However, a new class of materials promises to offer higher device reliability and… more
Abstract:UV diode detector arrays have a wide range of both commercial and military applications. Examples include spectral measurement and calibration, pollution monitoring, environmental change monitoring, remote sensing of earth resources, solar UV monitoring, burner monitoring in gas turbines, flame… more
Abstract:Ultrasonic imaging is potentially one of the most versatile diagnostic tools in medicine, yet it istransducer designs. New applications of acoustical microscopy, performed at frequencies above 200 MHminiature transducer geometries to enable in vivo applications and to enhance present in vitro… more
Abstract:We will develop a computer-assisted system to improve the ability of breast sonography to distinguifrom benign lesions. These are lesions originally detected by mammography and sent to ultrasound forThe lesions are biopsied when they are classified by ultrasound as solid or indeterminate, even… more
Abstract:A new barrier coating for protection of continuous SiC fibers in composites up to 1500C will be applied to continuous fiber tows by chemical vapor deposition (CVD) in commercial apparatus. Current SiC fibers, and currently used BN barrier coatings, are restricted to use below 1100C and are… 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.
