Introductory resource on nanoscience and molecular engineering stressing the interdisciplinary nature of the field

Principles of Nanoscience and Molecular Engineering introduces nanoscale principles in molecular engineering, providing hands-on experience and stressing the interdisciplinary nature of this field. The book integrates phenomenological knowledge of material and transport properties with atomistic and molecular theories, bridging the gap between unbound classical three-dimensional space and the constrained nanorealm.

The book challenges conventional wisdom derived from anecdotal experiences and fosters an understanding of nanoscale molecular collective phenomena that do not violate classical physical laws but rather expand upon them. The surprise exotic awe is replaced by improved insight into the workings of atoms and molecules under interfacial, dimensional, and size constraints.

Readers will find detailed insights on molecular phase behavior under confinement, the atom model and wave equation, quantum mechanics, the electronic structure of molecules and matter, molecular modes and energetic properties, self-assembly, and statical mechanics of pair interactions in gases.

Written by a highly qualified professor in chemical engineering with significant research contributions to the field, Principles of Nanoscience and Molecular Engineering includes information on:

• Shared perceptions of our world and their shortcomings, applied to the nanoscale, specifically to transport properties
• Structured condensed systems affected by interfaces and size constraints, examining the effect of non-interacting solid interfaces on liquid phases and free surfaces of solid crystal lattice arrangements
• The liquid condensed state, highlighting boundary conditions in thermally equilibrated systems
• Electronic transport in relation to the electronic structure of molecules, focusing on the movement of electrons through lower-dimensional systems

Principles of Nanoscience and Molecular Engineering serves as an excellent introductory resource on the subject for readers studying or working in related fields.

René M. Overney is Professor in Chemical Engineering at the University of Washington. His research interests include rational molecular engineering based on nanoscale fundamentals with a focus on enhanced electronic, photonic, ionic, energy, momentum and mass transport properties based on molecular relaxations and entropic cooperative properties in complex organic thin films. Overney's group has pioneered efforts in developing novel scanning probe methods towards mapping inter- and intra-molecular energetics and transitions in thin film and self-assembled systems.
