Book Description
A review study of nucleation and its role in determining grain size in solidification is presented. It is demonstrated that nucleation is an essential aspect of most phase transformation processes when the unstable phase is initially free of all fragments of the more stable phase to be formed. Occurrence of multi-nucleation events for many transformations; the required maintenance of a critical metastability for continued classical nucleation; and the feedback effect of crystal or cluster growth tending to destroy this metastability are emphasized. Limitation of grain density to the density of growth centers which can be generated by nucleation and then maintained is discussed. Secondary nucleation, which includes such processes as crystal fragmentation, is emphasized as a separate route from classical nucleation by which growth centers can be generated. A theoretical analysis of the interaction of homogeneous nucleation and crystal growth under ideal conditions is presented. Preliminary results predict grain density should vary with the 1.45 power of cooling rate. (Author).

Book Description
Current interest in research of solidification of melts is focussed to understand crystal nucleation and crystal growth. They determine the solidified product with its physical properties. A detailed description of these processes lead to the development and validation of physical models, which may form the basis of quantitative modelling of solidification routes in e.g. casting and foundry processes in order to develop a predictive capability in the design of materials during solidification. This book, based on a symposium held at EUROMAT 2003 aims to gives an overview on current developments in the research of solidification and crystallisation of liquids. The materials of interest range from metals and their alloys over semiconductors and isolators to organic substances.

Book Description
In Nucleation in Condensed Matter, key theoretical models for nucleation are developed and experimental data are used to discuss their range of validity. A central aim of this book is to enable the reader, when faced with a phenomenon in which nucleation appears to play a role, to determine whether nucleation is indeed important and to develop a quantitative and predictive description of the nucleation behavior. The third section of the book examines nucleation processes in practical situations, ranging from solid state precipitation to nucleation in biological systems to nucleation in food and drink. Nucleation in Condensed Matter is a key reference for an advanced materials course in phase transformations. It is also an essential reference for researchers in the field. Unified treatment of key theories, experimental evaluations and case studies Complete derivation of key models Detailed discussion of experimental measurements Examples of nucleation in diverse systems

Book Description
Nucleation of Water: From Fundamental Science to Atmospheric and Additional Applications provides a comprehensive accounting of the current state-of-the-art regarding the nucleation of water. It covers vapor-liquid, liquid-vapor, liquid-ice and vapor-ice transitions and describes basic kinetic and thermodynamic concepts in a manner understandable to researchers working on specific applications. The main focus of the book lies in atmospheric phenomena, but it also describes engineering and biological applications. Bubble nucleation, although not of major atmospheric relevance, is included for completeness. This book presents a single, go-to resource that will help readers understand the breadth and depth of nucleation, both in theory and in real-world examples. Offers a single, comprehensive work on water nucleation, including cutting- edge research on ice, cloud and bubble nucleation Written primarily for atmospheric scientists, but it also presents the theories in such a way that researchers in other disciplines will find it useful Written by one of the world’s foremost experts on ice nucleation
