Carbon foam and C-C have also been identified as ideal core materials for advanced high temperature heat… more
Abstract:There is a constant need to reduce the size and part counts of state-of-the-art (SOA) turbine engines. One already demonstrated solution, which offers significant weight and cost payoffs, uses advanced fuel-lubricated (fuel-lubed) bearing. The challenge associated with fuel lubrication is that the… more
Abstract:Current science for Mars and lunar exploration demands that fairly small diameter intact rock cores be acquired for geologic evaluation. Tools to acquire these cores must be light weight, draw minimal power, and induce low loads on their robotic platforms. Unfortunately no tools have yet been… 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.
