Microtransit with major impact
Two federal grants, $2.1 million from the NSF and $1.8 million from the DOE, are enabling engineers to reimagine how regional transit systems operate, making them more accessible and efficient. Both projects, headed by Abhishek Dubey, assistant professor of electrical engineering and computer science, are with the Chattanooga Area Regional… Read MoreOct. 1, 2020

Self-sealing technology corrects for pore size
Membrane desalination is an efficient way to desalinate water but maintaining uniformity of the pore size is a challenge. A single “large” hole can cause high leakage, compromise membrane performance and contaminate the water. How do you drill trillions of holes between the size of 0.3 and 0.6 nanometers over… Read MoreOct. 1, 2020

Team achieves solute-solute separation with sub-Angstrom precision
A research team that includes Vanderbilt engineers is the first to successfully separate two ions with minute small size differences, a major advancement in separation science with widespread potential application. Their process is first to achieve solute-solute separation with sub-Angstrom precision. An Angstrom is one hundred-millionth of a centimeter, or… Read MoreOct. 1, 2020
