Aquéllasis

Aquéllasis is a neologism used in some theoretical and speculative discussions to denote a proposed framework for analyzing how water networks interact with and reorganize around functional units in materials, biological systems, and nanostructured environments. The term blends elements associated with water with a suffix that signals a process or state, and it is not part of standard nomenclature in chemistry, biology, or physics. Usage is limited to a small set of publications and lecture contexts.

Conceptually, aquéllasis aims to describe transient connectivity among solvent molecules and solutes that enables rapid rearrangements of hydration shells, hydrogen-bond networks, or proton-transfer pathways. It emphasizes dynamic coupling between water structure and the activity of nearby macromolecules or surfaces. The framework is intended to complement established theories of solvation dynamics and hydration phenomena rather than replace them.

In practice, discussions of aquéllasis involve models and simulations of hydration dynamics, as well as proposed experimental approaches to probe water-mediated processes at interfaces and within complex assemblies. Proponents argue that the concept can help unify observations about rapid water rearrangements with functional outcomes in catalysis, transport, and sensing. Critics note that without clear definitions and reproducible methodologies, aquéllasis risks remaining a broad umbrella term rather than a distinct, testable theory.
