New lab safety video

If you’ve ever wondered about the machinery you see in the structures lab, take a look at the new lab safety video for the 500 kip compression machine.| Short Read

In the video, lab technician Bob Spence demonstrates the capability of the machine for compressing and shattering concrete blocks and cylinders.

Students, such as graduate student Ravi Ranade in the video, use the machine to test concrete materials for strength.

Watch the video below, and make sure you don’t go near it without proper safety training.

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
