Sentences with phrase «perform electron energy»

To perform electron energy gain and loss spectroscopy experiments, scientists place a sample material in the electron microscope.

Not exact matches

This calculation method enabled us to more accurately perform theoretical prediction of IMFP compared to the experimental value, which was obtained by applying spectrometry (extended X ‐ ray absorption fine structure spectrometry) to low - speed electrons of Copper and molybdenum at the high - brilliant synchrotron radiation facility, and to explain the relationship between energy measurement and the types of materials.

Experiments were performed at the National Center for Electron Microscopy in the Molecular Foundry at Berkeley Lab, which is supported by the U.S. Department of Energy.

The belts, consisting of high - energy electrons and protons discovered above Earth's upper atmosphere in 1958 by James Van Allen, can pose a significant hazard to satellites and spacecraft, as well to astronauts performing activities outside a spacecraft.

We already know the result of this experiment, because our early universe performed it for us about 13.8 billion years ago when it was that hot: Almost 100 percent of the matter got converted into energy, with less than one billionth remaining in the form of quarks and electrons, which make up all the matter we observe in our universe today.

Electrons moving through a leaf or a green sulfur bacterial bloom are effectively performing a quantum «random walk» — a sort of primitive quantum computation — to seek out the optimum transmission route for the solar energy they carry.
