Ozonolisys is a procedure of adding ozone to an unsaturated organic compound, by which first ozonides emerge, and then degrade.
Paper is the thin sheet of material made of cellulose pulp, derived mainly from wood, but also from rags and certain grasses, and processed into flexible leaves or rolls. It is manufactured by bleaching raw material using the bleaching-powder, mixing it with inorganic fillers, colours and glues, and drying. Used primarily for writing, printing, drawing, wrapping, and covering walls.
Pauli exclusion principle is the statement that two electrons in an atom cannot have identical all four quantum numbers. It was first formulated in 1925 by the Austrian-born Swiss physicst Wolfgang Ernst Pauli (1900-1958).
Peptisation is a process in which coagulated colloid returns into a dispersed state.
Percolation is a procedure of extraction of a material in special pipes through which a solvent is gradually released.
Crystal system is a method of classifying crystalline substances on the basis of their unit cell. There are seven unique crystal systems. The simplest and most symmetric, the cubic (or isometric) system, has the symmetry of a cube. The other six systems, in order of decreasing symmetry, are hexagonal, tetragonal, rhombohedral (also known as trigonal), orthorhombic, monoclinic and triclinic.

Potassium-argon dating is a process of determining the age of mineral deposits by measuring the proportion between quantity of isotope 40Ar and 40K in mineral deposits.
Preservatives are substances that will prevent the development of wood-destroying fungi, borers of various kinds, and other harmful insects that deteriorate wood.
Propagation is the step in a polymerization mechanism, where new monomer molecules are added to the growing polymer chain in the free radical process.
