Professor Athanasopoulos-Zekkos in new video

Professor Athanasopoulos-Zekkos's research is featured in the new video from MConneX titled, “Pile Driver Sensors.”| Short Read

When piles are driven into soil to provide foundational support for structures, vibrations are caused that can create cracks in deep foundations for nearby structures, like bridges.

Traditionally, these vibrations are measured by ground surface sensors, but the length needed to travel from deep underground in order to reach the sensors is telling only part of the story.

Assistant Professor Adda Athanasopoulos-Zekkos is taking a different approach by installing both geophones and accelerometers in depth and very close to the driven pile. This has given her team data that is first of its kind and will hopefully lead to a better understanding of how much soil settlement is produced in a construction site.

This research is the topic of a new video from MConneX titled, “Pile Driver Sensors.”

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
