CEE PhD student Avery Carlson has received the Water Environment Federation’s Technical Exhibition and Conference (WEFTEC)’s Martha Hahn Memorial Award. This award is presented to the highest-rated abstract in the Municipal Symposium track, which is also the largest and most competitive track at WEFTEC.

Carlson received the award for his paper, “Troubleshooting Long-term Biofouling by Dispersed Bacteria in Full-scale Membrane Bioreactor.” WEFTEC is the largest conference of its kind in North America and offers water quality professionals from around the world, the best water quality education and training available. WEFTEC serves as a forum for domestic and international business opportunities, and promotes invaluable peer-to-peer networking among registrants. WEFTEC was held in Chicago from September 21st to September 25th. Carlson presented his work at the conference on September 24th.

Carlson is a second year PhD candidate in the Environmental Biotechnology Group in the Department of Civil and Environmental Engineering. His focus is on wastewater treatment processes and nutrient recovery through the use of membrane technologies. He received his Master’s degree from University of Michigan in 2017, during which time he investigated fouling issues at Traverse City Regional Wastewater Plant’s membrane bioreactor. Carlson is advised by Professor Glen Daigger.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
