#kinetics

• Absorption — The physical or chemical process by which a substance (gas, liquid, or energy) enters the mass of another body; in clinical toxicology and pharmacokinetics, it represents the entry of a toxin or drug into the bloodstream through biological membranes.
• Adsorbent — A solid or liquid substance that provides the boundary surface or interface onto which atoms, molecules, or ions of a fluid adhere and accumulate during the adsorption process. Unlike an absorbent, which assimilates particles throughout its bulk volume, an adsorbent operates exclusively as a surface phenomenon driven by residual intermolecular Van der Waals forces or covalent chemical bonds. Adsorbents typically feature high porosity and an extensive specific surface area per unit mass.
• To adsorb — To attract, bind, and concentrate atoms, molecules, or ions from a fluid phase (gas or liquid) onto the surface or interface of a solid or liquid substrate. This physical or chemical process occurs via residual intermolecular forces or covalent bonds, strictly distinguished from the paronym verb 'to absorb', which entails penetration into the bulk volume. It is a spontaneous, typically exothermic surface-driven phenomenon.
• To ignite spontaneously — To catch fire by itself, spontaneously or automatically, under the action of a local increase in temperature, pressure, or due to an internal exothermic chemical reaction, without the direct intervention of an external spark or flame source.
• Auxonomic — Belonging or relating to the laws, mechanisms, and rules governing the growth and structural development processes of living organisms or complex dynamic systems; relating to auxonomy.
• Auxonomy — The set of laws, rules, or mathematical and biological principles governing the growth, volumetric expansion, and structural development processes of living organisms or complex dynamic systems; the theoretical study of the evolutionary kinetics of tissue dimensions.
• Auxotonic — Relating to or characterized by a muscular contraction in which the tension within the fibers progressively increases as the muscle shortens (elongates); specific to movements executed against a variable elastic resistance (such as stretching a spring or the ejection phases of the heart).
