types:
assorbimento
(physics) the process in which incident radiated energy is retained without reflection or transmission on passing through a medium
centrifugazione
the process of separating substances of different densities by the use of a centrifuge
diffusione
(physics) the process in which there is movement of a substance from an area of high concentration of that substance to an area of lower concentration
distillazione
the process of purifying a liquid by boiling it and condensing its vapors
deriva
the gradual departure from an intended course due to external influences (as a ship or plane)
estrazione
the process of obtaining something from a mixture or compound by chemical or physical or mechanical means
filtrazione
the process whereby fluids pass through a filter or a filtering medium
fossilizzazione
the process of fossilizing a plant or animal that existed in some earlier age; the process of being turned to stone
bradisismo
(geology) a natural process whereby geological features are modified
ionizzazione
the process of ionizing; the formation of ions by separating atoms or molecules or radicals or by adding or subtracting electrons from atoms by strong electric fields in a gas

sericoltura
raising silkworms in order to obtain raw silk
sinergia
the working together of two things (muscles or drugs for example) to produce an effect greater than the sum of their individual effects
traspirazione
the passage of gases through fine tubes because of differences in pressure or temperature
assorbimento
(chemistry) a process in which one substance permeates another; a fluid permeates or is dissolved by a liquid or solid

a process that impregnates something with calcium (or calcium salts)
catalisi
acceleration of a chemical reaction induced the presence of material that is chemically unchanged at the end of the reaction
reazione
(chemistry) a process in which one or more substances are changed into others
cancrena
decay of matter (as by rot or oxidation)
decadimento
the spontaneous disintegration of a radioactive substance along with the emission of ionizing radiation
emissione
the release of electrons from parent atoms
denudazione,
erosione
(geology) the mechanical process of wearing or grinding something down (as by particles washing over it)

riscaldamento
the process of becoming warmer; a rising temperature
meccanica
the atomic process that occurs during a chemical reaction
osmosi
(biology, chemistry) diffusion of molecules through a semipermeable membrane from a place of higher concentration to a place of lower concentration until the concentration on both sides is equal
saturazione
the process of permeating or infusing something with a substance
fotosintesi
synthesis of compounds with the aid of radiant energy (especially in plants)
polimerizzazione
a chemical process that combines several monomers to form a polymer or polymeric compound
sintesi
the process of producing a chemical compound (usually by the union of simpler chemical compounds)
fermentazione
a process in which an agent causes an organic substance to break down into simpler substances; especially, the anaerobic breakdown of sugar into alcohol
