DR. G. I. FINCH and A. G. QUARRELL1 have reported many extra rings in electron diffraction patterns from thin metal foils containing preferentially oriented crystals. At first they attributed ...

SO-CALLED extra or forbidden rings have been observed from time to time in electron diffraction patterns, and their origin has been attributed to half-order diffractions or impurities. Cases in ...

A new nanoscale transistor that parcels out electrons with metronome-like regularity has the potential to lead to designs for electronic noses and tiny devices inside of cell phones.

Posted: Jul 27, 2017: Observing electron beam etching atom by atom (Nanowerk News) Researchers have utilized electron beam irradiation to in situ etch CaO in a TEM, which permits simultaneous ...

The largest Rydberg atoms have electron orbits with a diameter on the order of a micrometer, which means that something like 160 atoms are within the orbit when the Rydberg atom is formed.

In a unique experiment, researchers have clocked how long it takes for an electron to be emitted from an atom. The result is .00000000000000002 seconds, or 20 billionths of a billionth of a second.

Researchers at Leti, a CEA Tech institute, recently developed an electron holography technique capable of imaging material structures with a spatial resolution of just one atom. Electron holography, a ...

A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other. This attraction holds the atom together. It is ...

The electron from each atom feels the attraction from the proton in the nucleus of the other atom. This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond ...

Almost a century later, Joseph John Thomson, a fellow Mancunian working the University of Cambridge in 1897, discovered the electron, proving that the atom had smaller constituent parts.
