Available in PDF, EPUB and Kindle. Book excerpt: Physical Chemistry, A Series of Monographs: Rotational Spectra and Molecular Structure covers the energy levels and rotational transitions. This book is divided into nine chapters that evaluate the rigid asymmetric top molecules and the nuclear spin statistics for asymmetric tops. Some of the topics covered in the book are the asymmetric rotor functions; rotational transition intensities; classes of molecules; nuclear spin statistics for linear molecules and symmetric tops; and classical appearance of centrifugal and coriolis forces. Other chapters deal with the energy levels and effects of centrifugal distortion, as well as the internuclear distance and moments of inertia. The discussion then shifts to the coriolis coupling effects on rotational constants and the perturbation treatment of vibration-rotational Hamiltonian. The last chapter is devoted to the examination of origin of the quadrupole interaction. The book can provide useful information to chemists, physicists, electrical engineers, students, and researchers.

Download or read book Flux Pinning in Superconductors written by Teruo Matsushita and published by Springer Science & Business Media. This book was released on 2014-02-20 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book covers the flux pinning mechanisms and properties and the electromagnetic phenomena caused by the flux pinning common for metallic, high-Tc and MgB2 superconductors. The condensation energy interaction known for normal precipitates or grain boundaries and the kinetic energy interaction proposed for artificial Nb pins in Nb-Ti, etc. are introduced for the pinning mechanism. Summation theories to derive the critical current density are discussed in detail. Irreversible magnetization and AC loss caused by the flux pinning are also discussed. The loss originally stems from the ohmic dissipation of normal electrons in the normal core driven by the electric field induced by the flux motion. The readers will learn why the resultant loss is of hysteresis type in spite of such mechanism. The influence of the flux pinning on the vortex phase diagram in high Tc superconductors is discussed and the dependencies of the irreversibility field are also described on other quantities such as anisotropy of superconductor, specimen size and electric field strength. Recent developments of critical current properties in various high-Tc superconductors and MgB2 are introduced. Other topics are: singularity in the case of transport current in a parallel magnetic field such as deviation from the Josephson relation, reversible flux motion inside pinning potentials which causes deviation from the critical state model prediction, the concept of the minimization of energy dissipation in the flux pinning phenomena which gives the basis for the critical state model, etc. Significant reduction in the AC loss in AC wires with very fine filaments originates from the reversible flux motion which is dominant in the two-dimensional pinning. The concept of minimum energy dissipation explains also the behavior of flux bundle size which determines the irreversibility line under the flux creep. The new edition has been thoroughly updated, with new sections on the progress in enhancing the critical current density in high temperature superconductors by introduction of artificial pinning centers, the effect of packing density on the critical current density and irreversibility field in MgB2 and derivation of the force-balance equation from the minimization of the free energy including the pinning energy.

Download or read book GaAs Microelectronics written by Norman G. Einspruch and published by Academic Press. This book was released on 2014-12-01 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: VLSI Electronics Microstructure Science, Volume 11: GaAs Microelectronics presents the important aspects of GaAs (Gallium Arsenide) IC technology development ranging from materials preparation and IC fabrication to wafer evaluation and chip packaging. The volume is comprised of eleven chapters. Chapter 1 traces the historical development of GaAs technology for high-speed and high-frequency applications. This chapter summarizes the important properties of GaAs that serve to make this material and its related compounds technologically important. Chapter 2 covers GaAs substrate growth, ion implantation and annealing, and materials characterization, technologies that are essential for IC development. Chapters 3-6 describe the various IC technologies that are currently under development. These include microwave and digital MESFET ICs, the most mature technologies, and bipolar and field-effect heterostructure transistor ICs. The high-speed capability of GaAs ICs introduces new problems, on-wafer testing and packaging. These topics are discussed in Chapters 7 and 8. Applications for GaAs ICs are covered in Chapters 9 and 10. The first of these chapters is concerned with high speed computer applications; the second addresses military applications. The book concludes with a chapter on radiation effects in GaAs ICs. Scientists, engineers, researchers, device designers, and systems architects will find the book useful.

Download or read book Introduction to Physical Polymer Science written by Leslie H. Sperling and published by John Wiley & Sons. This book was released on 2015-02-02 with total page 815 pages. Available in PDF, EPUB and Kindle. Book excerpt: An Updated Edition of the Classic Text Polymers constitute the basis for the plastics, rubber, adhesives, fiber, and coating industries. The Fourth Edition of Introduction to Physical Polymer Science acknowledges the industrial success of polymers and the advancements made in the field while continuing to deliver the comprehensive introduction to polymer science that made its predecessors classic texts. The Fourth Edition continues its coverage of amorphous and crystalline materials, glass transitions, rubber elasticity, and mechanical behavior, and offers updated discussions of polymer blends, composites, and interfaces, as well as such basics as molecular weight determination. Thus, interrelationships among molecular structure, morphology, and mechanical behavior of polymers continue to provide much of the value of the book. Newly introduced topics include: Nanocomposites, including carbon nanotubes and exfoliated montmorillonite clays The structure, motions, and functions of DNA and proteins, as well as the interfaces of polymeric biomaterials with living organisms The glass transition behavior of nano-thin plastic films In addition, new sections have been included on fire retardancy, friction and wear, optical tweezers, and more. Introduction to Physical Polymer Science, Fourth Edition provides both an essential introduction to the field as well as an entry point to the latest research and developments in polymer science and engineering, making it an indispensable text for chemistry, chemical engineering, materials science and engineering, and polymer science and engineering students and professionals.
