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.
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.
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 ...
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 ...
Part I, appearing in July 1913, described the quantum rules for electron orbits and quantum jumps in the hydrogen atom, explaining the spectrum of colors it emitted.
IF YOU have ever mined into a website looking for information, only to find yourself wandering around lost and wondering how to get out, then a new navigation interface developed at NUI Galway ...
An orbital structure is the space in an atom that’s occupied by an electron. But when describing these super-microscopic properties of matter, scientists have had to rely on wave functions — a ...
The quantum fix. Famed Danish physicist Niels Bohr was the first person to propose a solution to this issue. In 1913, he suggested that electrons in an atom couldn't just have any orbit they wanted.
