In atomic physics and quantum chemistry, the electron configuration is the arrangement of electrons in an atom, molecule, or other physical structure (e.g., a crystal). Like other elementary particles ...

Alloys created by mixing three atomic species (medium-entropy alloys, or MEAs) or five species or more (high-entropy alloys, or HEAs) have emerged as hot properties in materials science. In metallurgy ...

High-order harmonic generation (HHG) provides a main route to generate attosecond (10-18 s) pulses, which have been considered “the world’s fastest film camera” for imaging the movement of electrons.

MR. ROY GARDNER gave an interesting paper on “A Method of Setting out the Classification of the Elements” at a recent meeting of the New Zealand Institute. The paper included the accompanying Table, ...
