CEE Students build Sustainable Systems

CEE students plan to streamline their filter installation process at schools in Brazil.| Short Read

Several CEE undergraduate students have been actively involved in the Pantanal region of Brazil for the last several years. Their initial objective was to get a school constructed and operational in a remote fishing village; this school will be starting up next fall. Last summer, two CEE students, Greg Ewing (undergraduate) and Cory Vonachen (MSE, Environmental) constructed a biosand filter for water treatment for the school. An official from the Ministry of Education saw it and remarked that there were some thirty other schools in the region that could use such facilities. This summer represents the beginning of the implementation of that program and a group of about a dozen students are currently in Brazil. In the future, they hope to partner with Brazilian university students to further this project. The following link was produced by the College of Engineering and describes a bit about the project and the group’s efforts this last winter term to streamline their filter installation process. Julie Bateman, who just graduated with her BSE in Civil Engineering was one of the founders of the Patanal Partnership. She was recently profiled here as one of about five graduating seniors across the university.

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
