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 ...

Unlike Scanning Electron Microscopy that bounces electrons off the surface of a sample to produce an image, Transmission Electron Microscopes (TEMs) shoot the electrons completely through the sample.

In this video excerpt from NOVA's "Hunting the Elements," New York Times technology columnist David Pogue examines how atomic structure determines reactivity. Meet Theo Gray, chemist and author, who ...

Unlike the electron beam used in scanning and transmission electron microscopy (SEM, TEM), the beam in a focused ion beam system (FIB) is composed of gallium (Ga) ions. The ions forming the structure ...

Since the FE-SEM is in effect an electrical circuit, the specimen must be conductive. In the tungsten source SEM, any nonconductive specimen is coated with a very thin layer of conductive material in ...

The idea of dynamical decoupling originated in spin echo 16,17 in nuclear magnetic resonance, in which a single flip of nuclear spins by a radio pulse makes the noises ‘felt’ by the spins before and ...

Scientists have made the most accurate measurement yet of the shape of the humble electron, finding that it is almost a perfect sphere. The experiment suggests that if the electron were magnified to ...
