Описание: Physical Ultrasonics of Composites is a rigorous introduction to the characterization of composite materials by means of ultrasonic waves. Composites are treated here not simply as uniform media, but as inhomogeneous layered anisotropic media with internal structure characteristic of composite laminates. The objective here is to concentrate on exposing the singular behavior of ultrasonic waves as they interact with layered, anisotropic materials, materials which incorporate those structural elements typical of composite laminates. This book provides a synergistic description of both modeling and experimental methods in addressing wave propagation phenomena and composite property measurements. After a brief review of basic composite mechanics, a thorough treatment of ultrasonics in anisotropic media is presented, along with composite characterization methods. The interaction of ultrasonic waves at interfaces of anisotropic materials is discussed, as are guided waves in composite plates and rods. Waves in layered media are developed from the standpoint of the Stiffness Matrix, a major advance over the conventional, potentially unstable Transfer Matrix approach. Laminated plates are treated both with the stiffness matrix and using Floquet analysis. The important influence on the received electronic signals in ultrasonic materials characterization from transducer geometry and placement are carefully exposed in a dedicated chapter. Ultrasonic wave interactions are especially susceptible to such influences because ultrasonic transducers are seldom more than a dozen or so wavelengths in diameter. The book ends with a chapter devoted to the emerging field of air-coupled ultrasonics. This new technology has come of age with the development of purpose-built transducers and electronics and is finding ever wider applications, particularly in the characterization of composite laminates.

Описание: This is a comprehensive textbook designed forgraduate and advanced undergraduate students. Both authors rely on more than 20years of teaching experience in renowned Physics Engineering courses to writethis book addressing the students’ needs.Kinetics and Spectroscopy of Low Temperature Plasmasderives in a full self-consistent way the electron kinetic theory used todescribe low temperature plasmas created in the laboratory with an electrical discharge,and presents the main optical spectroscopic diagnostics used to characterizesuch plasmas. The chapters with the theoretical contents make use of adeductive approach in which the electron kinetic theory applied to plasmaswith basis on the electron Boltzmann equation is derived from the basicconcepts of Statistical and Plasma Physics. On the other hand, the mainoptical spectroscopy diagnostics used to characterize experimentally such plasmasare presented and justified from the point of view of the Atomic and MolecularPhysics.Low temperature plasmas (LTP) are partially ionized gases with a broaduse in many technological applications such as microelectronics, light sources,lasers, biology and medicine. LTPs lead to the production of atomic andmolecular excited states, chemically reactive radicals, and activated surfacesites, which are in the origin, among others, of the deposition of thin films,advanced nanotechnology products, solar cells, highly efficient combustionmotors, and treatment of cancer cells.

Описание: Increasing numbers of physicists, chemists, and mathematicians are moving into biology, reading literature across disciplines, and mastering novel biochemical concepts. To succeed in this transition, researchers must understand on a practical level what is experimentally feasible. The number of experimental techniques in biology is vast and often specific to particular subject areas; nonetheless, there are a few basic methods that provide a conceptual underpinning for broad application. Introduction to Experimental Biophysics is the ideal benchtop companion for physical scientists interested in getting their hands wet. Assuming familiarity with basic physics and the scientific method but no previous background in biology or chemistry, this book provides: * A thorough description of modern experimental and analytical techniques used in biological and biophysical research * Practical information and step-by-step guidance on instrumentation and experimental design * Recipes for common solutions and media, lists of important reagents, and a glossary of biological terms used Developed for graduate students in biomedical engineering, physics, chemical engineering, chemistry, mathematics, and computer science, Introduction to Experimental Biophysics is an essential resource for scientists to overcoming conceptual and technical barriers to working in a biology wet lab.
Описание: The critically acclaimed laboratory standard for more than forty years, Methods in Enzymology is one of the most highly respected publications in the field of biochemistry. Since 1955, each volume has been eagerly awaited, frequently consulted, and praised by researchers and reviewers alike. Now with mo than 300 volumes (all of them still in print), the series contains much material still relevant today--truly an essential publication for researchers in all fields of life sciences.
