Understanding chorus waves is vital, as they create fast-moving, highly energetic electrons (known as killer electrons) that ...

Achieving practical interstellar travel requires overcoming the immense challenge of reaching extraordinary velocities. To ...

In scanning electron microscopy, a thermionic electron source such as a tungsten filament is usually used. The subject of this tutorial, the Hitachi S-4700 FE-SEM, utilizes a cold cathode field ...

Common detectors pick up back-scattered electrons bouncing back toward the electron source. There are also low-energy electrons bouncing off in random directions, depending on the topology of the ...

I used to have access to some pretty nice Scanning Electron Microscopes (a SEM) at my day job. While they are a bit more complex than a 3D printer, they are awfully handy when you need them.

Attosecond science, honored with the 2023 Nobel Prize in Physics, is transforming our understanding of how electrons move in ...
