| chemical principles 7e: Chemical Thermodynamics: Advanced Applications J. Bevan Ott, Juliana Boerio-Goates, 2000-06-16 This book is an excellent companion to Chemical Thermodynamics: Principles and Applications. Together they make a complete reference set for the practicing scientist. This volume extends the range of topics and applications to ones that are not usually covered in a beginning thermodynamics text. In a sense, the book covers a middle ground between the basic principles developed in a beginning thermodynamics textbook, and the very specialized applications that are a part of an ongoing research project. As such, it could prove invaluable to the practicing scientist who needs to apply thermodynamic relationships to aid in the understanding of the chemical process under consideration. The writing style in this volume remains informal, but more technical than in Principles and Applications. It starts with Chapter 11, whichsummarizes the thermodynamic relationships developed in this earlier volume. For those who want or need more detail, references are given tothe sections in Principles and Applications where one could go to learn more about the development, limitations, and conditions where these equations apply. This is the only place where Advanced Applications ties back to the previous volume. Chapter 11 can serve as a review of the fundamental thermodynamic equations that are necessary for the more sophisticated applications described in the remainder of this book. This may be all that is necessary for the practicing scientist who has been away from the field for some time and needs some review. The remainder of this book applies thermodynamics to the description of a variety of problems. The topics covered are those that are probably of the most fundamental and broadest interest. Throughout the book, examples of real systems are used as much as possible. This is in contrast to many books where generic examples are used almost exclusively. A complete set of references to all sources of data and to supplementary reading sources is included. Problems are given at the end of each chapter. This makes the book ideally suited for use as a textbook in an advanced topics course in chemical thermodynamics. - An excellent review of thermodynamic principles and mathematical relationships along with references to the relevant sections in Principles and Applications where these equations are developed - Applications of thermodynamics in a wide variety of chemical processes, including phase equilibria, chemical equilibrium, properties of mixtures, and surface chemistry - Case-study approach to demonstrate the application of thermodynamics to biochemical, geochemical, and industrial processes - Applications at the cutting edge of thermodynamics - Examples and problems to assist in learning - Includes a complete set of references to all literature sources |

| chemical principles 7e: Chemistry of Pyrotechnics Chris Mocella, John A. Conkling, 2010-12-23 Primarily driven by advancing technology and concerns for safety, advancement in the world of pyrotechnics and high-energy materials has exploded in the past 25 years. The promulgation of new government regulations places new and more stringent restrictions on the materials that may be used in energetic mixtures. These regulations now mandate numerous training programs, and initiate other actions, such as OSHA’s Process Safety Management standard, intended to eliminate accidents and incidents. Unfortunately, the US lacks an organized, broad-range academic program to cover the science and use of energetic materials and educate the next generation of pyrotechnicians. Designed as a bridge to allow a smooth and confident transition for personnel coming from a chemistry background into the practical world of explosives, Chemistry of Pyrotechnics: Basic Principles and Theory, Second Edition emphasizes basic chemical principles alongside practical, hands-on knowledge in the preparation of energetic mixtures. It examines the interactions between and adaptations of pyrotechnics to changing technology in areas such as obscuration science and low-signature flame emission. Much more than a simple how-to guide, the book discusses chemical and pyrotechnic principles, components of high-energy mixtures, and elements of ignition, propagation, and sensitivity. It offers heat compositions, including ignition mixes, delays, thermites, and propellants and investigates the production of smoke and sound as well as light and color. Promoting the growth and expansion of pyrotechnics as a science, Chemistry of Pyrotechnics: Basic Principles and Theory, Second Edition provides practitioners with the ability to apply chemical principles and logic to energetic materials and thereby make the field as productive, useful, and safe as possible. |

| chemical principles 7e: Physical and chemical principles of nanotechnology Naveen Kumar J R, P. Prasad, 2019-04-29 Document from the year 2019 in the subject Physics - Nuclear Physics, grade: A, , course: Nanotechnology, language: English, abstract: Physical and chemical principles of nanotechnology present the subject with the aim of providing information about Quantum Mechanics, Basics of Thermodynamics, Lattice Vibrations and Band Theory of Solids, Semiconductors and Tunneling & Colloidal Systems. This work is primarily intended to be a textbook for bachelor degree students in engineering, science and technology. This book has crucial role to play in the curriculum of all branches of engineering and technology. Quantum mechanics is a physical science dealing with the behaviour of matter and energy on the scale of atoms and subatomic particles/waves. It also forms the basis for the contemporary understanding of how huge objects such as stars and galaxies, and cosmological events such as the Big Bang, can be analyzed and explained. Quantum mechanics is the foundation of several related disciplines including nanotechnology, condensed matter physics, quantum chemistry, structural biology, particle physics, and electronics. The term quantum mechanics was first coined by Max Born in 1924. The acceptance by the general physics community of quantum mechanics is due to its accurate prediction of the physical behaviour of systems, including systems where Newtonian mechanics fails. Even general relativity is limited in ways quantum mechanics is not for describing systems at the atomic scale or smaller, at very low or very high energies, or the lowest temperatures. Through a century of experimentation and applied science, the quantum mechanical theory has proven to be very successful and practical. The foundations of quantum mechanics date from the early 1800s, but the real beginnings of QM date from the work of Max Planck in 1900. Albert Einstein and Niels Bohr soon made essential contributions to what is now called the old quantum theory. |

| chemical principles 7e: The Energy of Nature E. C. Pielou, 2008-09-15 Energy is crucial for events of every kind, in this world or any other. Without energy, nothing would ever happen. Nothing would move and there would be no life. The sun wouldn't shine, winds wouldn't blow, rivers wouldn't flow, trees wouldn't grow, birds wouldn't fly, and fish wouldn't swim; indeed no material object, living or dead, could even exist. In spite of all this, energy is seldom considered a part of what we call nature. In The Energy of Nature, E. C. Pielou explores energy's role in nature—how and where it originates, what it does, and what becomes of it. Drawing on a wide range of scientific disciplines, from physics, chemistry, and biology to all the earth sciences, as well as on her own lifelong experience as a naturalist, Pielou opens our eyes to the myriad ways energy and its transfer affect the earth and its inhabitants. Along the way we learn how energy is delivered to the earth from the sun; how it causes weather, winds, and tides; how it shapes the earth through mountain building and erosion; how it is captured and used by living things; how it is stored in chemical bonds; how nuclear energy is released; how it heats the unseen depths of the planet and is explosively revealed in the turmoil of earthquakes and volcanoes; how energy manifests itself in magnetism and electromagnetic waves; how we harness it to fuel human societies; and much more. Filled with fascinating information and and helpful illustrations (hand drawn by the author), The Energy of Nature is fun, readable, and instructive. Science buffs of all ages will be delighted. “A luminous, inquiring, and thoughtful exploration of Earth’s energetics.”—Jocylyn McDowell, Discovery |
