Abstract:…. In Phase I, we propose two barcoding methods to trace transcripts back to single cell sources. The Phase I effort will form a basis for Phase II studies that will scale the technology to the full transcriptome and for analysis of different cell types, such as yeast and algae… more
Abstract:Cooling water systems in thermal power plants are notoriously difficult to maintain because they provide the ideal, warm environments for the growth of algae and bacteria. This biofouling can lead to corrosion and cracking of cooling pipes in heat exchangers. Conventionally,… more
Abstract:There is an urgent need for domestic sources of low-cost, large-scale renewable biofuels. Micro-algae are one of most promising sources of renewable energy, with high potential per-acre oil productivity, minimal competition with arable land and limited freshwater supplies, and… more
Abstract:This Small Business Innovation Research (SBIR) Phase I project will employ an innovative approach to metabolically engineer algae and enable low-cost, carbon-free hydrogen production at medium to large scale. One approach to achieving high hydrogen production involves the use of… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project plans to refine and test prototype facilities for commercialization of on-farm algae production and harvesting. Algae will be utilized initially for livestock feed and in future for bio-fuel. The… more
Abstract:One of the principal technical and cost barriers to successful commercialization of algal biofuels as an alternative energy source is the inability to extract the useful oil components from the algae in an economical and environmentally sound fashion. Indeed, the DOE… more
Abstract:… filtration and adsorptive media. The size exclusion step will remove all three classes of microbes (Protozoa, Bacteria, and Virus) to levels satisfying purification status including passing the NSF P248 test protocol. This filtration stage will also remove turbidity, algae… more
Abstract:A novel process is proposed which will allow continuous dewatering of algae growth culture in a device which is robust (no moving parts) and readily scalable through process parallelization. The process makes use of innovative passive (low energy input) flow control and does not… more
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… more
Abstract:…. For example, solvent recovery by the superior membrane filtration technology will be of great value in processing other oil seeds such as corn, cotton seed and canola. Other applications of the proposed membrane filtration technology include solvent recovery from algae… more
Abstract:This Small Business Innovation Research Phase I project will develop a method for lysing algae and recovering the oil without pre-concentrating or dewatering. A promising feedstock for biofuels is photosynthetic algae, which can produce lipids in much higher yields per acre then… more
Abstract:One of the most promising biomass sources for fuels and other feedstocks is photosynthetic algae. Algae can produce lipids, proteins, and other compounds, and can be grown in salt water. Current production practices rely on expensive means of harvesting, concentrating, and… more
Abstract:This Small Business Innovation Research (SBIR) Phase II project addresses the need for innovative approaches to harvesting oil from bio-algae, specifically to dewater the bio-algae and recycle the processed algae stream for reuse. The subject innovation will… more
Abstract:Algae are one of the most, if not the most, productive biomass crops known and have a photosynthetic efficiency almost twice that of the most productive terrestrial crop, sugarcane. However, algae are not without disadvantages relative to terrestrial crops, and do require their… more
Abstract:…, if their concentration is thought to be incorrect, they are discarded into the environment and replaced with a new solution. This leads to nutrient waste and widespread environmental contamination of aquatic, ground and drinking water that causes blooms of harmful algae… 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.
