Electron microscopes are used to observe a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, metals, and crystals.

Electron microscopes are expensive to build and maintain, but the capital and running costs of confocal light microscope systems now overlaps with those of basic electron microscopes.

Electron microscopes equipped for X-ray spectroscopy can provide qualitative and quantitative elemental analysis.

Electron beam excitation is used in electron microscopes, scanning electron microscopes ( SEM ) and scanning transmission electron microscopes ( STEM ).

Transmission Electron Micrograph of DislocationsSome microscopes also permit the in-situ heating and / or deformation of samples, thereby permitting the direct observation of dislocation movement and their interactions.

Electron optics calculations are, besides other uses, needed for electron microscopes and are also crucial for the design of modern particle accelerators.

Electron spectrometers are used on a range of scientific equipment, including particle accelerators, transmission electron microscopes, and astronomical satellites.

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

Following the merger of Fisher Scientific with Thermo Electron Corporation in November 2006, Oxoid Ltd ( along with Remel Inc ) became a division of Thermo Fisher Scientific.

He became globally recognized as a leader in Microwave research and headed the development of GE ’ s Electron microscope.

This meant the Electron had a lifespan not much shorter than those more popular micros and much longer than competitors such as the Oric-1 and Dragon 32.

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 ).

There were also many popular games officially converted to the Electron from arcade machines ( including Crystal Castles, Tempest, Commando, Paperboy and Yie Ar Kung-Fu ) or other home computer systems ( including Impossible Mission, Jet Set Willy, The Way of the Exploding Fist, Tetris, The Last Ninja, Barbarian and SimCity ).

Pro Electron took the popular European coding system in use from around 1934 for valves ( tubes ), the Mullard – Philips tube designation, and essentially re-allocated several of the rarely-used heater designations ( first letter of the part number ) for semiconductors.

* In Romania, Maestro is a popular debit card ( the third one after Visa Electron and MasterCard Standard Debit ), is still the main debit card issued by 3 banks: Unicredit-Tiriac Bank, Intesa SanPaolo and RIB, another 5 banks are issuing Maestro as a secondary debit card, these are: BCR, BRD, Raiffeisen, Carpatica and Emporiki.

In countries that have stricter criteria for issuing credit cards Visa Electron has become popular with younger people and students.

Electron beam lithography was most popular during the 1970s, but was replaced in popularity by X-ray lithography during the 1980s and early 1990s, and then by EUV lithography from the mid-1990s to the mid-2000s.

Electron microscopic examination of the Af sample showed it to be composed of nearly isotropic particles about 0.3M in diameter.

Electron states are best represented by time-depending " mixtures " ( linear combinations ) of multiple orbitals.

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

The Electron was able to save and load programs onto audio cassette via a supplied converter cable that connected it to any standard tape recorder that had the correct sockets.

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.

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

The Electron was developed during 1983 as a cheap sibling for the BBC Micro with the intention of capturing the low-cost Christmas sales market for that year.

Despite this, several features that would later be associated with BBC Master and Archimedes were first features of Electron expansion units, including ROM cartridge slots and the Advanced Disc Filing System — a hierarchical improvement to the BBC's original Disc Filing System.

The Cartridge-port ROM-slots provided additional control lines, ( compared to the lines available via the Edge-connector on the rear of the Electron ), such as ROMSTBY, SNDIN, ROMQA, and some additional Voltage sources (+ 16V ) etc.

This enabled the Electron to achieve the same functionality as that provided by the Expansion-ROM slot on the bottom-left of the BBC Micro B keyboard.

The Plus 3 included an uprated Power-supply unit, that was designed to power the Plus 3, in addition to the Electron and the Plus 1 interface as well.

As a games machine the Electron shared the same failing as the Sinclair Spectrum in not having a joystick port.

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.

By providing extra storage this modification also allowed some games and applications intended for the BBC Micro to function on the Electron despite the lack of a native Mode 7.

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

Of the capabilities present in the BBC Micro but absent from the Electron, the teletext-style mode 7 was particularly conspicuous because of the very low memory usage in that mode ( just less than 1 kB ) and the high number of BBC programs that used it.

Although cheap and effective in enabling use of some software that only used official ROM entry points for text output, this solution proved very slow because the Electron had to be placed into an 80-byte-pitch display to be able to get anywhere near to reproducing mode 7 and the CPU spent a lot of time drawing approximations of mode 7 characters and graphics that in a hardware solution would be achieved without any CPU processing.

During the latter years, PMS produced a 2nd Processor specifically for the Electron.

An unusual variant of the Electron was sold by British Telecom Business Systems as the BT Merlin M2105 Communications Terminal.

This consisted of a de-badged Electron plus a large expansion unit containing 32 KB of RAM, 48 KB of ROM, a Centronics printer port and a modem.

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 '

Like the BBC Micro, the Electron was constrained by limited memory resources.

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.
