- Actinogenesis — A physical process, natural or artificial, through which rays or radiations are generated, produced, and emitted, particularly within the short-wave electromagnetic spectrum, such as ultraviolet radiation, X-rays, or gamma rays. This structural phenomenon constitutes a subject of study in nuclear physics and radiology, being essential for understanding the emission mechanisms of radiant sources, celestial bodies, or technological devices used in industrial medical imaging.
- Atomlysis — A rare conceptual term or neologism used in advanced spectroscopy and analytical chemistry to describe the process of complete splitting, dissociation, or decomposition of a molecule into its free constituent atoms, under the action of extreme heat, electric arcs, or high-power lasers. Unlike other chemical dissociations, atomlysis requires breaking all intramolecular bonds to bring the substance into a purely atomic state.
- Avogadro — The surname of the celebrated Italian physicist and chemist Amedeo Avogadro (1776–1856), globally recognized for his fundamental contributions to the development of molecular theory. In exact sciences, his name is directly associated with 'Avogadro's number' and 'Avogadro's law', essential constants and structural principles defining the proportions between gas volume and the number of molecules contained at a given pressure and temperature.
