Vesihydraatio

Vesihydraatio is a term used in Finnish-language chemistry literature to describe hydration processes in which water molecules interact with or add to a substrate, resulting in hydrated products or altered physical properties. The concept encompasses both chemical hydration, where water becomes part of the molecular structure, and physical hydration, where water associations modify solvation and dynamics without necessarily forming new covalent bonds. The exact usage of the term can vary by field, but it generally centers on the role of water in changing reactivity, stability, or structure.

In organic chemistry, vesihydraatio often refers to hydration reactions of unsaturated substrates, such as the addition of water across carbon–carbon multiple bonds to give alcohols or alcohol-like products, typically under catalytic conditions. In inorganic and coordination chemistry, it may describe the formation of aqua complexes when metal centers bind water molecules. In biochemistry and materials science, vesihydraatio can denote hydration shells around biomolecules or hydrated films and vesicles, where water influences conformational dynamics, solubility, and interfacial properties.

Applications of vesihydraatio span synthesis, catalysis, and materials design. In synthesis, controlled hydration enables selective formation of alcohols and hydrates. In nanoscience and drug delivery, hydration effects govern stability, swelling, and release from vesicles or polymer matrices. Because definitions and emphasis differ among disciplines, the term is best understood within its specific scientific context.
