Three-dimensional

Nanomaterials whose three (3) dimensions exceed the nanoparticle range (i.e., 1–50 nm).

Two-dimensional

Nanomaterials which have two (2) dimensions exceeding the nanoparticle range.

One-dimensional

Nanomaterials which have one (1) dimension exceeding the nanoparticle range

Zero-dimensional

Nanomaterials whose three (3) dimensions never exceed the nanoparticle range

Levigation

The process of washing away the impurities from powdered ore, leaving the required metals to precipitate

Froth Flotation

The process of mixing powdered ore with water and a small amount of oil within a tank, with the air blown inside the tank, creating a froth that carries the important metals to the surface

Liquation

The process of heating the ore, allowing the metal with the lower melting point to collect at the bottom, leaving the impurities

Magnetic Separation

The process of separating the ore from the impurities by means of magnetic manipulation

Leaching

The process of adding chemicals that can effectively dissolve the required metals in a powdered ore, leaving the impurities behind

Calcination

The process of converting oxide and carbonate ores into metal oxides by heating the enriched ores in the absence of air

Roasting

The process of converting sulfide ores into metal oxides by heating the enriched ores in the presence of air

Copper

ductile metal, resistant to corrosion, with very high thermal and electrical conductivity. Pure copper is soft and malleable; a freshly exposed surface has a reddish-orange color

Organic Compounds

Compounds comprising mostly of carbon (C), hydrogen (H₂), and oxygen (O₂), which are the building blocks of living things

Hydrocarbons

Compounds mostly made up of C and H₂

Aliphatic

C - H compounds forming open chains

Alkanes

group of saturated hydrocarbons whose single-bond C - C chains form an open tree structure

Condensation reaction

reaction where two (2) or more molecules combine to form a larger molecule, at the expense of losing some smaller molecules simultaneous to the reaction (usually water or methanol

Addition reaction

Involves unsaturated compounds containing double (or triple) bonds
