CEE researchers earn best paper award from ES&T Letters

Environmental Science & Technology Letters select CEE students' paper as one of the best papers that merit inclusion. | Short Read

Environmental Science & Technology (ES&T) Letters has selected four papers from 2015 that merited inclusion in their awards for best papers.

One of the papers that ES&T Letters chose to recognize was written by Graduate Student Jeseth Delgado Vela and co-authored by Graduate Student Lauren Stadler, Alumna Kelly Martin, Professor Lutgarde Raskin, Professor Nancy Love and Charles Bott of Hampton Roads Sanitation District.

Their paper is titled, “Prospects for Biological Nitrogen Removal from Anaerobic Effluents during Mainstream Wastewater Treatment.” According to the summary, “They concluded that development of effective nitrogen removal technologies will require the development of sensor-mediated controls, improved computational models, and improved removal efficiency relative to reducing energy demands.”

ES&T Letters is an international forum for brief communications on experimental or theoretical results of exceptional timeliness in all aspects of environmental science (pure and applied), and short reviews on emerging environmental science & technology topics.

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
