Civil and Environmental Engineering PhD student Katherine Dowdell was selected by the National Water Research Institute (NWRI) to receive an NWRI-Biolargo Graduate Fellowship to support her research project on optimizing filter backwashing practices to reduce pathogens in drinking water. Katherine (Kate) is advised by Professor Lutgarde Raskin.

The NWRI-BioLargo Fellowship research must pertain to developing and/or enhancing water supplies. The fellowship provides $5,000 per year, for up to two years. Up to four students may be awarded the fellowship in a given year.

NWRI is a nonprofit organization that works to advance innovative water resources management practices. Biolargo, Inc. is a sustainable science, technology, and full-service environmental engineering company that works to develop innovative water treatment technology to solve pressing water challenges, while using as little electrical energy as possible.

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
