amounts of waste and reduces the availability of natural
resource.
Linear geometry
An arrangement of three or more atoms along a single
direction.
M
MAP
Modified Atmosphere Packaging, use of an inert gas instead
of air to prevent oxidation.
Mass spectroscopy Analytical technique that allows to measure the mass of
fragments generated from a starting molecular compound by
high energy bombardment.
MEA
Monoethanolamine, an organic species containing the
amino (NH 2 ) and alcohol (OH) moieties, of formula
H 2 NCH 2 CH 2 OH, used for the capture of CO 2 .
Merchant market
