Abstract:Manufacturers of military batteries often need raw materials that may have long lead times, limited production and/or high costs. During Phase I of this project, Advanced Membrane Systems (AMS) made some modifications and improvements to one of its products (a lithium ion battery separator), and… more
Abstract:DESCRIPTION (provided by applicant): Cardiovascular disease (CVD) is the number 1 killer in the United States and much of the Western world. Treatment of the disease costs billions of dollars each year and the costs continue to rise exponentially. If consi
dered as a separate condition outside of… more
Abstract:DESCRIPTION (provided by applicant): This Small Business Technology Transfer Phase I project will develop a prototype online perchlorate monitor for a resin bed perchlorate remediation reactor. The device will be have less than 4 ppb limit- of-detection, p
rovide results in less than 3 min., and… more
Abstract:The recent emergence of the Silicon Drift detector (SDD), for use in Energy Dispersive x-ray Spectroscopy (EDS), has made possible x-ray event streams with input count rates in the range of 1-10 Mcps. Modern digital pulse processors are therefore required to run at fast time constants to achieve… more
Abstract:The Small Business Innovation Research (SBIR) Phase I project will develop a novel Omni-Directional Antireflective Coating (Omni-AR) to improve light collection in photovoltaic cells. The coating consists of a monolayer of microscale silica particles partially immersed into a film of spin-on glass.… more
Abstract:This proposal details the feasibility, design, implementation, risk mitigation, and plan for construction of prototype millimeter-wave, electronically tunable filters. Such a technology can achieve near fixed frequency filter performance while tuning over a respectable bandwidth enabling… more
Abstract:DESCRIPTION (provided by applicant): MRI is a proven non-invasive technique to make functional MRI (fMRI) by measuring changes in blood oxygen level dependent (BOLD) contrast in different regions of the brain resulting from the neurovascular coupling of
neuronal activity. Echo planar imaging… more
Abstract:Orion requires a rendezvous and docking sensor to provide relative navigation information during proximity operations and docking. In order to dock, the sensor must provide full six degree of freedom (6 DOF) relative position and relative attitude information at a rate sufficient for the rendezvous… 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.
