Oonliitos

Oonliitos is a term used in materials science and engineering to describe a type of cohesive connection between elements such as particles, surfaces, or phases that forms without a traditional mechanical fastener or rigid interface. It covers a range of non-mechanical bonding mechanisms that fuse components into a single structural unit, often at the micro- or nanoscale.

The term is of Finnish origin, with liitos meaning joint or connection, and oon- used as a prefix in some technical vocabularies to indicate a phenomenon or process. In practice, oonliitos appears in discussions of interfacial phenomena, surface chemistry, and the design of advanced materials where bonding is governed by interfacial forces rather than screws, welds, or clamps.

Mechanisms of oonliitos can include electrostatic attraction, hydrogen bonding, van der Waals forces, capillary effects, and chemical interactions created through surface functionalization. The concept allows for both reversible and irreversible binding, depending on environmental conditions such as temperature, humidity, pH, or solvent.

Oonliitos can be classified by attributes such as reversibility, strength, and interface type (solid–solid, solid–liquid, or solid–gas). It is distinguished from mechanical bonding by its reliance on interfacial forces and the properties of the contacting surfaces rather than a separate fastener.

Applications of oonliitos are found in self-assembly, nanocomposites, protective coatings, bioengineering scaffolds, flexible electronics, and sensor technologies. Because the term is not universally standardized, definitions and emphasis may vary across disciplines. See also adhesion, cohesion, interfacial chemistry, binding energy, and self-assembly.
