More About This Title Nanotechnology: Basic Calculations for Engineers and Scientists
English
Because nanosized particles possess unique properties, nanotechnology is rapidly becoming a major interest in engineering and science. Nanotechnology: Basic Calculations for Engineers and Scientists-a logical follow-up to the author's previous text, Nanotechnology: Environmental Implications and Solutions-presents a practical overview of nanotechnology in a unique workbook format.
The author has developed nearly 300 problems that provide a clear understanding of this growing field in four distinct areas of study:
* Chemistry fundamentals and principles
* Particle technology
* Applications
* Environmental concerns
These problems have been carefully chosen to address the most important basic concepts, issues, and applications within each area, including such topics as patent evaluation, toxicology, particle dynamics, ventilation, risk assessment, and manufacturing. An introduction to quantum mechanics is also included in the Appendix. These stand-alone problems follow an orderly and logical progression designed to develop the reader's technical understanding.
"This is certain to become the pacesetter in the field, a text to benefit both students of all technical disciplines and practicing engineers and researchers."
-Dr. Howard Beim, Professor of Chemistry, U.S. Merchant Marine Academy
"Dr. Theodore has covered most of the important nanotechnology subject matter in this ...work through simple, easy-to-follow problems."
-John McKenna, President and CEO, ETS, Inc.
