Riassunto

One of the most striking phenomena in condensed matter physics is the occurrence of abrupt transitions in the structure of a substance at certain temperatures or pressures. These are first order phase transitions, and examples such as the freezing of water are familiar in everyday life. The conditions at which the transformation takes place can sometimes vary. For example, the freezing point of water is not always 0°C, but the liquid can be supercooled considerably if it is pure enough and treated carefully. The reason for this phenomenon is nucleation.

This monograph covers all major available routes of theoretical research of nucleation phenomena (phenomenological models, semi-phenomenological theories, density functional theories, microscopic and semi-microscopic approaches), with emphasis on the formation of liquid droplets from a metastable vapor. Also, it illustrates the application of these various approaches to experimentally relevant problems.

In spite of the familiarity of the involved phenomena, it is still impossible to calculate nucleation accurately, as the properties and the kinetics of the daughter phase are insufficiently well known. Existing theories based upon classical nucleation theory have on the whole explained the trends in behavior correctly. However they often fail spectacularly to account for new data, in particular in the case of binary or, more generally, multi-component nucleation. The current challenge of this book is to go beyond such classical models and provide a more satisfactory theory by using density functional theory and microscopic computer simulations in order to describe the properties of small clusters. Also, semi-phenomenological models are proposed, which attempt to relate the properties of small clusters to known properties of the bulk phases.

This monograph is an introduction as well as a compendium to researchers in soft condensed matter physics and chemical physics, graduate and post-graduatestudents in physics and chemistry starting on research in the area of nucleation, and to experimentalists wishing to gain a better understanding of the efforts being made to account for their data.

Dalla quarta di copertina

This monograph covers the major available routes of theoretical research of nucleation phenomena––phenomenological models, semi-phenomenological theories, density functional theories and microscopic approaches––with emphasis on the formation of liquid droplets from a metastable vapor. It also illustrates the application of these various approaches to experimentally relevant problems.

In spite of familiarity with the involved phenomena, it is still not possible to accurately calculate nucleation rate, as the properties of the daughter phase are insufficiently known.

Existing theories based upon the classical nucleation theory have on the whole explained the trends in behavior correctly. However, they often fail spectacularly to account for new data, in particular in the case of binary or, more generally, multi-component nucleation. This book challenges such classical models and provides a more satisfactory description by using density functional theory and microscopic computer simulations to describe the properties of small clusters. Also, semi-phenomenological models are proposed that relate the properties of small clusters to known properties of the bulk phases.

This monograph is an introduction as well as a compendium to researchers in the areas of soft condensed matter physics, chemical physics, graduate and post-graduate students in physics and chemistrystarting on research in the area of nucleation, and to experimentalists wishing to gain a better understanding of the recent developments being made to account for their data.
