Could very fine gas bubbles suspended in certain liquids improve the efficiency of life support functions in space? Researchers at UMaine, USM, and Arizona State University will investigate this question with a $753,750 NASA grant to the Maine Space Grant Consortium and $350,000 in matching funds from the three institutions. Researchers will create nanobubbles then study their stability through a series of tests in microgravity and zero-gravity environments. The NASA grant was awarded through EPSCoR, the Established Program to Stimulate Competitive Research. The project will be overseen by Onur Apul, assistant professor of environmental engineering at UMaine.
