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:… for dry adhesives would improve product safety, reduce environmental impact from messy liquids, and improve educational experiences for children. In labels, an easily removable adhesive would eliminate residue glue, in turn simplifying and increasing recyclability of… 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: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:… comprise greater than 25% of total U.S. wastewater flow. The AET system is projected to be life cycle cost competitive with currently available nutrient removal technologies in the single home arena. It is eminently modular and adaptable to a wide variety of recycling and… 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
Abstract:… play a pivotal role in achieving both the energy and the life support needs of extraterrestrial bases. For example, the Martian atmosphere, which is predominately CO2, can be directly used as a feedstock for the production of both fuel and water. The water can then be … 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.
