Aldehyde condensation polymer, any of a number of industrially produced polymeric substances (substances composed of extremely large molecules) that are built up in condensation reactions involving an aldehyde.
Polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers.
Intermetallic compound, any of a class of substances composed of definite proportions of two or more elemental metals, rather than continuously variable proportions (as in solid solutions).
All these groups of substances have one thing in common they are all polymers (substances composed of large molecules formed from smaller ones), produced by applications of a rapidly growing branch of chemistry, polymer chemistry, established in the early 1930s.
Most surface coatings employed in industry and by consumers are based on synthetic polymers that is, industrially produced substances composed of extremely large, often interconnected molecules that form tough, flexible, adhesive films when applied to surfaces.
The more electrons and holes there are, and the faster they flow, the bigger the current will be.Perovskites are substances composed of what are known as cubo-octahedral crystals in other words, cubes with the corners cut off.
Alloys are substances composed of two or more metals or of a metal and a nonmetal that are intimately united, usually by dissolving in each other when they are melted.
Usually at least 100 monomer molecules must be combined to make a product that has certain unique physical properties such as elasticity, high tensile strength, or the ability to form fibres that differentiate polymers from substances composed of smaller and simpler molecules; often, many thousands of monomer units are incorporated in a single molecule of a polymer.
As material, fine substances, composed of particles, combined from air and fire, they can, as we have seen, be either inanimate or animate.
These known and many unknown antioxidant substances compose the body's complex antioxidant system.
