Electron degeneracy pressure is a quantum-mechanical effect arising from the Pauli exclusion principle.

* Electron degeneracy pressure

Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure.

Electron degeneracy pressure results from the same underlying mechanism that defines the electron orbital structure of elemental matter.

Electron degeneracy pressure in a material can be computed as.

where is the breakdown potential in volts DC, and are constants that depend on the surrounding gas, represents the pressure of the surrounding gas, represents the distance in centimetres between the electrodes, and represents the Secondary Electron Emission Coefficient.

Therefore banks will issue a Visa Electron card to customers who may not qualify for credit.

In some cases, especially in the UK, rather than issuing Electron to customers who should not be allowed to go overdrawn, banks will issue what is ostensibly a full Visa Debit card that authorises online for every transaction, in exactly the same manner as Electron.

Electron beam welding has already been demonstrated on board the Skylab, and will probably be the method of choice in space.

Electron pairs are therefore considered lone pairs if two electrons are paired but are not used in chemical bonding.

& TOTSE ( Temple Of The Screaming Electron ) was -- if functioning -- a members-only BBS by 2000.

* Conductor → Electron head if exactly one or two of the neighbouring cells are electron heads, or remains Conductor otherwise.

At its peak, the Electron was the third best selling micro in the United Kingdom, and total lifetime game sales for the Electron exceeded those of the BBC Micro.

During its decline, Master RAM Boards were added to every Electron in an attempt to increase sales.

FireTrack exploits a division in the way the Electron handles its display — of the seven available graphics modes, two are configured so that the final two of every ten scanlines are blank and are not based on the contents of RAM.

In order to keep track of its position within the display, the Electron maintains an internal display address counter.

Electron beam lithography is also important commercially, primarily for its use in the manufacture of photomasks.

The first detection of tau neutrino interactions was announced in summer of 2000 by the DONUT collaboration at Fermilab, making it the latest particle of the Standard Model to have been directly observed ; its existence had already been inferred by both theoretical consistency and experimental data from the Large Electron – Positron Collider.

* Electron magnetic dipole moment, the magnetic moment of an electron caused by its intrinsic property of spin

Electron binding energy ( BE ), more accurately, is the energy required to release an electron from its atomic or molecular orbital when adsorbed to a surface rather than a free atom.

Electron capture is the primary decay mode for isotopes with a relative superabundance of protons in the nucleus, but with insufficient energy difference between the isotope and its prospective daughter ( with one less positive charge ) for the nuclide to decay by emitting a positron.

Other current developments include the installation of a Scanning Electron Microcope, the first of its kind in Europe, in December 2010.

The Silicon Gate Technology with self-aligned gates was presented by its developer Federico Faggin at the IEEE International Electron Device Meeting on October 23, 1968 in Washington D. C ..

Like its main rival, Visa Electron, Solo cards required all transactions receive electronic authorisation from the issuing bank.

Alternative methods that are non or less physically invasive and less expensive per individual test have been used and are continuing to be developed, such as those using computed tomography ( CT ; led by the Electron Beam Tomography form, given its greater speed ) and magnetic resonance imaging ( MRI ).

Its first article, " Electron ", was written on May 30, 2003, yet its Main Page ( Halaman utama ) was created six months later on November 29.

All games that could be ( and weren't considered ' too old ') were ported to the Acorn Electron after its release in 1983 and almost all new games were now released for these 2 machines.

These include the arcade adventure Castle Quest ( BBC only ) by Tony Sothcott, billed as " Probably the most challenging game ever devised for the BBC Micro " ( it was never converted for the Electron, probably because it used near full-screen scrolling in an 8-colour mode ), Doctor Who and the Mines of Terror ( BBC, C64, CPC ), a huge arcade adventure that required its own ROM chip to run on the Model B BBC Micro, and the puzzle / platform game Imogen ( BBC only, later ported to Electron by Superior Software and more recently remade for PC ) by Michael St. Aubyn which was noted for its witty, original puzzles and cute high-resolution monochrome graphics.

In a 2010 post to the Stardot forum, Harte explained at length his reasons for creating the format: being the first to address emulation of the Acorn Electron and its primary medium, tape, Harte wanted a fine-grained and technically optimal representation of media, compared to existing ad-hoc formats ; and to package the multiple media elements of a software release into a single file, so that downloading a UEF is " more like obtaining the original product ".

* Electron – capture mass spectrometry

Electron ionization is widely used in mass spectrometry, particularly for organic molecules.

In 1982 Heim's mass formula was programmed on a computer at the German Electron Synchrotron DESY in Hamburg with the assistance of some resident scientists.

Electron microscopes, mass spectrometry and various forensic techniques allowed scientists unique glimpses of the state of health in Egypt 4000 years ago.

The Acorn Electron is a budget version of the BBC Micro educational / home computer made by Acorn Computers Ltd.

There are at least 500 known games for the Electron and the true total is probably in the thousands.

If Acorn had thought to include this small modification in the original Electron design it is likely the machine would have had a much greater impact as it would have nearly doubled the amount of motion possible in games and saved modes 0 – 3 ( including the only 16 colour mode ) from being nearly useless due to contended memory timings.

The Electron is widely misquoted as operating at 1. 79 MHz after measurements derived from speed testing against the thoroughly 2 MHz BBC Micro for various pieces of ' common software '

Notable popular games particularly associated with the Electron include: Crystal Castles ( video game ) | Crystal Castles is an example of a popular arcade game officially ported to the Electron ( US Gold ).

Electron software is predominantly archived in the UEF file format.

Electron gas can undergo plasma oscillation, which is waves caused by synchronized variations in electron density, and these produce energy emissions that can be detected by using radio telescopes.

Electron beam lithography ( EBL ) is a method of etching semiconductors at resolutions smaller than a micron.

Electron beam processing is used to irradiate materials in order to change their physical properties or sterilize medical and food products.

The Transmission Electron Aberration-corrected Microscope is capable of sub-0. 05 nm resolution, which is more than enough to resolve individual atoms.

Electron counting is a formalism used for classifying compounds and for explaining or predicting electronic structure and bonding.

# Electron in the initial state is represented by a solid line with an arrow pointing toward the vertex (→•).

# Electron in the final state is represented by a line with an arrow pointing away from the vertex: (•→).

Electron beam lithography as it is usually practiced is a form of maskless lithography, in that a mask is not required to generate the final pattern.

Electron beam lithography ( often abbreviated as e-beam lithography ) is the practice of scanning a beam of electrons in a patterned fashion across a surface covered with a film ( called the resist ), (" exposing " the resist ) and of selectively removing either exposed or non-exposed regions of the resist (" developing ").

Electron capture is the main decay mode for isotopes lighter than the < sup > 51 </ sup > V.

* July 10 – Donald Crowhurst's trimaran Teignmouth Electron is found drifting and unoccupied.

Electron paramagnetic resonance, otherwise known as Electron Spin Resonance ( ESR ) is a spectroscopic technique similar to NMR, but uses unpaired electrons instead.
