Bohr turned to Planck's quantum theory to explain the stability of most ... absorbs or gives off energy (as in light or heat), the electron jumps to higher or lower orbits. Bohr published these ...

Scientists have created an ultrashort electron beam with five times more peak current than any other similar beam on Earth.

At the time, he and others believed a handful of compounds must have these bonds. Electron theory was just a few decades old, and scientists were chipping away at the nature of atoms in fits and ...

THE great interest with which the electron theory of metals has been received by physicists is due chiefly to two reasons. The first is the practical importance of metals and their great variety ...

Density functional theory (DFT) is a cornerstone tool of modern physics, chemistry, and engineering used to explore the ...

Current concepts in light and electron microscopy and scanning probe techniques. Theory and practice of fluorescence (including confocal and multi-photon), atomic force, scanning and transmission ...
