Professor Gronewold’s video on Great Lakes ice

In a new video from MConneX, Adjunct Professor Andrew Gronewold discusses the implications of ice cover and frigid water on the lakes' future water levels and the shipping and tourism industries that depend on them.| Short Read

Gronewold explains why the record levels of ice on the Great Lakes may not have as big an impact as we might think, and how better tools will help engineers measure levels in the future.

In addition to his role with CEE, Gronewold is a physical scientist at the National Oceanic and Atmospheric Administration. His research interests include hydrological and water quality modeling with a focus on propagating uncertainty and variability into model-based management decisions. Specific research areas include predicting runoff in engaged basins and recreational water quality dynamics in Great Lakes Beaches.

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
