Alumnus Dr. Steven Chapra (PhD ’82) has been selected to receive the 2016 Wesley W. Horner Award from ASCE, making him one of two (first) authors to win the award in two consecutive years, as well as the fourth two-time recipient in the award’s 48-year history.

The award is presented to the lead author of the paper that makes the most valuable contribution to the environmental engineering profession. Chapra’s paper is titled, “Sed2K: Modeling Lake Sediment Diagenesis in a Management Context.” Co-authors include Rasika Gawde, Martin Auer and Noel Urban of Michigan Technological University and Rakesh Gelda of Upstate Freshwater Institute.

Chapra and co-author Martin Auer earned their PhDs from CEE with Professor Ray Canale as their advisor. Chapra says that he and Auer go to U-M football games together and they planned this paper in Ann Arbor prior to one of the 2013 games.

The award will be presented to Chapra in May 2016 at the World Environmental and Water Resources Congress in Florida.

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
