METHODS AND PROCESSES
7 method families group the 26 instrument investigations by the physical interaction each one relies on, so several investigations sharing a method are not read as several methods. Editorial classification of this atlas
Light emitted, absorbed or scattered by a sample carries the energy differences available to its atoms and molecules.
A focused probe forms a magnified picture of a specimen's surface or interior.
Waves scattered from an ordered structure interfere, so the pattern constrains the arrangement that produced it.
A mixture is separated by a physical property before its parts are counted.
Charge moving through a material or across an interface responds to composition and condition.
A material's response to heat, load or time reveals structure that is invisible at rest.
Radiation reaching a detector from a distant or radioactive source carries information about where it came from.
PROCESSES
Where the atlas already discusses a named process, this points at the passages. It describes none of them itself. 17 of the 40 processes searched for are not mentioned anywhere, which is a coverage gap rather than a claim about their importance.
Not mentioned anywhere: Hall–Héroult aluminum smelting, Bayer process, Kroll process, Czochralski crystal growth, Bessemer converter, Electrowinning and electrorefining, Froth flotation, Blast-furnace ironmaking, Calcination, Zone refining, Chlor-alkali process, Ostwald process, Solvent extraction, Chemical vapor deposition, Polymerisation, Catalytic cracking, Stellar nucleosynthesis.
