Abstract:… magnet manufacturing facility, about 20-30% of the magnetsare wasted as scrap, which is an estimated 1500-2500 tons/year. In the case of Sm-Co magnets, about 15-30% of the raw materials are wasted as scrap at a typical Sm-Co manufacturing site. Therefore, the recycling… more
Abstract:… and reduced reverse salt flux compared to conventional membranes. It is more chemically stable, enabling the development of a system that uses a draw solute which can capture carbon dioxide from flue gas. The draw solute can obtain high osmotic pressure and is recyclable… more
Abstract:This Phase I SBIR addresses the need for a manufacturing method for recovery and recycle of metal removed during electrochemical machining (ECM). Direct current (DC) ECM uses viscous solutions with additives such as fluoride resulting in difficult to control electrolytes,… more
Abstract:Recovery and re-use of Rhenium is of critical importance to the superalloy industry due to its limited availability and growing demand. The recycling loop in the superalloy industry is currently far less efficient.The proposal addresses the recovery of Rh
Abstract:… pristine GaAs surface with its original thickness. All mechanical polishing is eliminated in this proposed work, ensuring a constant substrate thickness through repeated substrate reclaim cycles and also drastically reducing the estimated cost of the recycling process… more
Abstract:Electronic waste (e-waste) is one of the most rapidly growing waste problems worldwide. Improper handling of e-waste results in vast amounts of toxic waste being sent to landfill and leaching into the water supply. Due to these concerns e-waste recycling is a rapidly growing… more
Abstract:… application of this material where it could be of substantial benefit to the warfighter. Creare"s innovative Cryogenic Machining approach addresses this need by dramatically increasing processing speed and tool life, and eliminating lubricant capture and recycling… more
Abstract:… the potential to meet the entire projected U.S. REE demand over the next decade utilizing a small fraction of the annual production of the domestic raw materials. Our approach is complementary, but far more efficient, than other methods of recovering REE, e.g., recycling… more
Abstract:… these radiation-induced defects, the mechanical and physical properties of the tungsten will be degraded. In addition, radioactive materials increase the cost of operation due to concerns with occupational exposure, accident conditions, and long-term storage/recycling. … more

Abstract:…, fase and economical process. In Phase I we demonstrated that high surface area magnetite particles embedded in wood are highly efficient in reducing P to ultra low levels (as much as 0.01 mg/L). The adsorbed P can be recovered from the media and potentially recycled as… more
Abstract:… share. The industry seeks products with higher quality, consistency and performance that address environmental concerns, while remaining cost competitive. The material which has been developed meets or exceeds all required performance standards, and its high recycle content… more
Abstract:… commercial opportunity for a platform technology with the ultimate potential to transform the industrial and residential water treatment landscape. Future applications may include ultrahigh efficiency water deionization, softening, and industrial wastewater recycling,… more
Abstract:… stream being utilized is largely scrapped into landfills today. From an environmental and health risk standpoint, PVC is problematic. Worldwide, government agencies and NGOs are seeking alternatives for PVC replacement. Furthermore, PVC cannot be easily recycled, and… more
Abstract:This Small Business Innovation Research Phase I project will effectively and efficiently recycle post-consumer plastic materials for high value applications through an innovative and environmentally benign approach known as solid-state shear pulverization (SSSP). SSSP subjects… more

Abstract:… lower system weight and cost for equivalent production. With respect to the latter, lifetimes beyond 1600 h of continuous operation in accelerated aging test have already been demonstrated. Our design philosophy is to produce robust, inexpensive, and fully recyclable modules… more
Abstract:…d cement for use in concrete accounts for roughly 5% of global CO2 emissions. A common practice in the production of Portland cement concrete (PCC) to reduce CO2 emissions levels is the partial substitution of cement with supplementary cementitious materials (SCMs) from … 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.
