EWRE Ph.D. Candidate Jeremy Guest receives the Walter J. Weber Jr. Award

In January, Jeremy Guest was awarded the Walter J. Weber, Jr. Award in Environmental and Energy Sustainability.| Short Read

The award honors students who have made “significant research contributions in the area of environmental and/or energy sustainability”. For his dissertation, Jeremy is evaluating the sustainability of using phototrophic microorganisms to recover energy and fertilizer from municipal wastewater, and the implementation of a sustainable design methodology for resource recovery design in wastewater management. His co-advisors are Drs. Nancy Love and Steve Skerlos.

Mr. Bobby Levine from the Chemical Engineering department was a co-recipient of the award this year.

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
