Improving bridge safety; Highlight of Professor Lynch and Kamat’s research (video)

Associate professors Jerome Lynch and Vineet Kamat aim to improve the safety and effectiveness of bridges through wireless sensor communication in their NIST project.| Short Read

According to Lynch, there are 600,000 bridges in the United States, and 25% of those are structurally deficient or functionally obsolete.

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
