magnon

A magnon is a quasiparticle representing a quantized spin wave in a magnetic material. In other words, it is a collective excitation of the spins of electrons in a magnetic solid, analogous to the...

Manufacturing Automation Protocol

A computerized token-passing local area network (LAN) configuration adopted by General Motors for real time control over the mediation of interconnected devices from multiple manufacturers over the...

matrix-assisted laser desorption/ionization

Process of analysis in which the analyte substance is distributed in a matrix before laser desorption. This method avoids the mass limitations associated with laser desorption and possibly enhances...

megabit — The megabit (also expressed as Mbit) is equivalent to one million (or 106) of the standard unit for digital information storage in telecommunications which is the bit.

megabyte — The megabyte (also expressed as Mbyte) is equivalent to one million (106) of the standard unit for digital information storage in computing which is the byte.

MB/s

megabytes per second — The megabyte per second (not to be mixed up with the Mb/s -- megabits per second) is a unit of data transfer rate equivalent to one million (106) bytes per second over a given information network.

Mb/s

megabits per second — The megabit per second (not to be mixed up with the mbit/s – millibit per second, or Mbitps- megabit picosecond) is a unit of data transfer rate equivalent to one million (or 106) bits per second over a given information network.

medical lasers

Medical lasers are devices that produce intense beams of light with specific characteristics and properties, which are used for various medical applications. These lasers emit light in the form of...
