Nanoclusters and Microparticles in Gases and Vapors

This book explores various processes involving small particles in gaseous environments, including transport, charging, and growth dynamics. Nanoclusters and Microparticles in Gases and Vapors offers insightful analysis and practical models.

In Nanoclusters and Microparticles in Gases and Vapors, the author delves into a variety of processes that involve small particles, particularly focusing on their behavior in gaseous environments. The book covers transport processes, charging mechanisms, and chemical interactions of small particles, as well as phenomena like atom attachment and the quenching of excited atomic particles on surfaces. It also discusses nucleation, coagulation, coalescence, and the growth dynamics of both particles and aggregates, providing a comprehensive overview of these intricate processes.

The text emphasizes the historical development of these concepts, many of which were established 50 to 100 years ago primarily for dense media. By employing these foundational ideas, the author explores the behavior of small particles in gases under two contrasting regimes: the kinetic regime, where surrounding atoms of a buffer gas do not influence the small particles, and the diffusion regime, where interactions are governed by hydrodynamic laws. This duality allows for a nuanced understanding of particle dynamics in different gas conditions.

To facilitate the analysis of these processes, the book utilizes established models such as the liquid drop model and the hard sphere model. These frameworks, originally introduced by notable physicists like N. Bohr and J. C. Maxwell, enable detailed calculations and estimations of process rates. Each chapter concludes with analytic formulas and criteria for validity, ensuring readers can apply these insights to real-world scenarios involving small particles. The exploration of various real objects and processes enhances the practical relevance of the theories presented in Nanoclusters and Microparticles in Gases and Vapors.
