Abstract:Solvent extraction by hexane is the most common choice for extraction of oil/lipids from algae. However, hexane is not the best choice of solvent for algae oil extraction because of the need to market byproducts for human and animal consumption. Oil and hexane from the solvent extraction process are… more
Abstract:Vapors produced during the process of refueling cars are a significant source of Volatile Organic Compounds (VOCs) emissions. Uncontrolled emissions cause economic losses and pollute the environment. This problem is exacerbated when the gasoline contains bioethanol because its presence increases the… more
Abstract:Soybean is the major source for production of edible oils worldwide and in United States. Pressing of the soybean into flakes followed by the solvent extraction with hexane (solvent) is most widely practiced for extraction of oil. Separation of solvent from oil-solvent mixture for solvent recovery… 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.
