Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

It predicts that electrons should show diffraction effects with crystals ... is given by X=(Planck's constant A)/(the momentum of an electron). As this wave train passes through matter, each ...

Experiments suggest that an unusual magnetic material can help harness energy from the planet’s rotation. But not everyone is convinced. Electricity can be generated from the energy of Earth ...

This new method describes an experimental concept called ultrafast vortex electron diffraction, which allows for direct ...

Ultrafast electron imaging reveals never-before-seen nuclear motions in hydrocarbon molecules triggered by light. The ...
