Introductory kinetics for the undergrad materials scientist
Materials Kinetics Fundamentals is an accessible andinteresting introduction to kinetics processes, with a focus onmaterials systems. Designed for the undergraduate student, thisbook avoids intense mathematics to present the theory andapplication of kinetics in a clear, reader-friendly way. Studentsare first introduced to the fundamental concepts of kinetics, withillustrated diagrams, examples, text boxes, and homework questionsthat impart a unified, intuitive understanding. Further chapterscover the application of these concepts in the context of materialsscience, with real-world examples including silicon processing andintegrated circuit fabrication, thin-film deposition, carbon-14dating, steel degassing, energy conversion, and more. Instructormaterials including PowerPoint presentations, a test bank, and moreare available through the companion website, providing a completeresource for the undergraduate materials science student.
At its core, kinetics deals with rates, telling us how fastsomething will take place - for example, how fast water willevaporate, or how fast molten silicon will solidify. This book isdesigned to provide students with an introduction to kinetics'underlying principles, without rigorous math to distract fromunderstanding.
* Understand universally important kinetic concepts likediffusion and reaction rate
* Model common kinetic processes both quantitatively andqualitatively
* Learn the mechanisms behind important and interesting materialssystems
* Examine the behaviors, properties, and interactions of relevantsolid materials
There are a large number of books on chemical kinetics, butthere are far fewer that focus on materials kinetics, and virtuallynone that provide an accessible, introductory-level treatment ofthe subject. Materials Kinetics Fundamentals fills thatneed, with clear, detailed explanations of these universalconcepts.
