Water, with its simple molecular structure, reveals a complex nature upon interaction with other molecules and surfaces. Water at Interfaces: A Molecular Approach provides a broad, multidisciplinary introduction to water at interfaces, focusing on its molecular characteristics. The book considers interfaces at different length scales from single water molecules to involvement of large numbers of water molecules, and from one-dimensional to three-dimensional interfaces. It begins with individual water molecules, describing their basic properties and the fundamental concepts that form the basis of this book. The text explores the main interfaces involving pure and ion-free condensed (liquid and solid) water, including water vapor/liquid water, liquid/oil, and liquid/solid interfaces. It examines water molecules on ideal surfaces-well-ordered (crystalline) and defect-free-covering topics such as electronic structure using frontier orbitals and substrate-induced structuring. The book discusses the affinity of water to surfaces, hydrophobicity and hydrophilicity, emphasizing two extreme cases of affinity. It then addresses real solid surfaces where water/solid interfaces play a key role in actual working conditions, examining water purification, photocatalytic activity, corrosion and degradation, and atmospheric agents. The final chapter deals with the interaction of water with the heterogeneous and complex surfaces of biomolecules, which can both influence the structure of the surrounding water and be modulated by the surrounding liquid. The author discusses simple to more complex biomolecules from peptides to proteins, nucleic acids, and membranes.

Phenomena associated with the adhesion interaction of surfaces have been a critical aspect of micro- and nanosystem development and performance since the first MicroElectroMechanicalSystems(MEMS) were fabricated. These phenomena are ubiquitous in nature and are present in all systems, however MEMS devices are particularly sensitive to their effects owing to their small size and limited actuation force that can be generated. Extension of MEMS technology concepts to the nanoscale and development of NanoElectroMechanicalSystems(NEMS) will result in systems even more strongly influenced by surface forces.
