This new edition of our 2016 book provides insight into designing intelligent materials and structures for special application in engineering. Literature is updated throughout and a new chapter on optics fibers has been added. The book discusses simulation and experimental determination of physical material properties, such as piezoelectric effects, shape memory, electro-rheology, and distributed control for vibrations minimization.
It is difficult to imagine how our highly evolved technological
society would function, or how life would even exist on our planet,
if polymers did not exist. The intensive study of polymeric
systems, which has been under way for several decades, has recently
yielded new insights into the properties of assemblies of these
complex molecules and the physical principles that govern their
behavior. These developments have included new concepts to describe
aspects of the many body behavior in these systems, microscopic
analyses that bring our understanding of these systems much closer
to our understanding of simple liquids and solids, and the
discovery of novel chemistry that these molecules can catalyze.
The book includes several topics as per Universities curriculum of M.Sc. and M.Phil. course work in Chemistry. This covers different Physiological aspects of Bioinorganic Chemistry in terms of 4 Chapters with in-depth and up-to-date coverage. The book symmetrically presents (i) Coordination chemistry of chlorophylls/bacteriochlophylls and its functional aspects in photosynthesis, (ii) Complexes containing nitric oxide: Synthesis, reactivity, structure, bonding, and therapeutic aspects of nitric oxide releasing molecules (NORMS) in human beings and plants, (iv) Complexes containing carbon monoxide: Synthesis, reactivity, structure, bonding, and therapeutic aspects of carbon monoxide releasing molecules (CORMS) in human beings and plants, and (iv) Advantageous role of gaseous signaling molecule, H2S: Hydrogen sulphide and their respective donors, in ophthalmic diseases and physiological implications in plants. At the end, three relevant topics are included as appendices for updating students and faculty members.
The knowledge about crystal structure and its correlation with physical properties is the prerequisite for designing new materials with taylored properties. This work provides for researchers and graduates a valuable resource on various techniques for crystal structure determinations. By discussing a broad range of different materials and tools the authors enable the understanding of why a material might be suitable for a particular application.
Neutrinos play a decisive part in nuclear and elementary particle physics, as well as in astrophysics and cosmology. Because they interact so weakly with matter, some of their basic properties, such as mass charge conjugation symmetry, are largely unknown. These subjects are considered in detail by authors, who also discuss such topics as neutrino mixing, neutrino decay, neutrino oscillations, double beta decay and related ideas. Physical concepts are stressed, and both theoretical methods and experimental techniques are presented. This second edition contains an expanded coverage of new experimental results and recent theoretical advances. In the intervening years since the first edition, many then unresolved problems such as tritium beta decay and reactor neutrino oscillations have been clarified. This edition also gives expanded coverage of solar and supernova neutrinos.

Niels Bohr, who pioneered the quantum theory of the atom, had a broad conception of his obligations as a physicist. They included not only a responsibility for the consequences of his work for the wider society, but also a compulsion to apply the philosophy he deduced from his physics to improving ordinary people's understanding of the moral universe they inhabit. In some of these concerns Bohr resembled Einstein, although Einstein could not accept what he called the "tranquilizing philosophy" with which Bohr tried to resolve such ancient conundrums as the nature (or possibility) of free will. In this Very Short Introduction John Heilbron draws on sources never before presented in English to cover the life and work of one of the most creative physicists of the 20th century. In addition to his role as a scientist, Heilbron considers Bohr as a statesman and Danish cultural icon, who built scientific institutions and pushed for the extension of international cooperation in science to all nation states. As a humanist he was concerned with the cultivation of all sides of the individual, and with the complementary contributions of all peoples to the sum of human culture. Throughout, Heilbron considers how all of these aspects of Bohr's personality influenced his work, as well as the science that made him, in the words of Sir Henry Dale, President of the Royal Society of London, probably the "first among all the men of all countries who are now active in any department of science." ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.
This book presents a self-contained derivation of van der Waals and Casimir type dispersion forces, covering the interactions between two atoms but also between microscopic, mesoscopic, and macroscopic objects of various shapes and materials. It also presents detailed and general prescriptions for finding the normal modes and the interactions in layered systems of planar, spherical and cylindrical types, with two-dimensional sheets, such as graphene incorporated in the formalism. A detailed derivation of the van der Waals force and Casimir-Polder force between two polarizable atoms serves as the starting point for the discussion of forces: Dispersion forces, of van der Waals and Casimir type, act on bodies of all size, from atoms up to macroscopic objects. The smaller the object the more these forces dominate and as a result they play a key role in modern nanotechnology through effects such as stiction. They show up in almost all fields of science, including physics, chemistry, biology, medicine, and even cosmology. Written by a condensed matter physicist in the language of condensed matter physics, the book shows readers how to obtain the electromagnetic normal modes, which for metallic systems, is especially useful in the field of plasmonics.
In the twenty-first century, we take the means to measure time for granted, without contemplating the sophisticated concepts on which our time scales are based. This volume presents the evolution of concepts of time and methods of time keeping up to the present day. It outlines the progression of time based on sundials, water clocks, and the Earth's rotation, to time measurement using pendulum clocks, quartz crystal clocks, and atomic frequency standards. Time scales created as a result of these improvements in technology and the development of general and special relativity are explained. This second edition has been updated throughout to describe twentieth- and twenty-first-century advances and discusses the redefinition of SI units and the future of UTC. A new chapter on time and cosmology has been added. This broad-ranging reference benefits a diverse readership, including historians, scientists, engineers, educators, and it is accessible to general readers.

Plasma Atomic Physics provides an overview of the elementary processes within atoms and ions in plasmas, and introduces readers to the language of atomic spectra and light emission, allowing them to explore the various and fascinating radiative properties of matter. The book familiarizes readers with the complex quantum-mechanical descriptions of electromagnetic and collisional processes, while also developing a number of effective qualitative models that will allow them to obtain adequately comprehensive descriptions of collisional-radiative processes in dense plasmas, dielectronic satellite emissions and autoionizing states, hollow ion X-ray emissions, polarized atoms and ions, hot electrons, charge exchange, atomic population kinetics, and radiation transport. Numerous applications to plasma spectroscopy and experimental data are presented, which concern magnetic confinement fusion, inertial fusion, laser-produced plasmas, and X-ray free-electron lasers' interaction with matter. Particular highlights include the development of quantum kinetics to a level surpassing the almost exclusively used quasi-classical approach in atomic population kinetics, the introduction of the recently developed Quantum-F-Matrix-Theory (QFMT) to study the impact of plasma microfields on atomic populations, and the Enrico Fermi equivalent photon method to develop the "Plasma Atom", where the response properties and oscillator strength distribution are represented with the help of a local plasma frequency of the atomic electron density. Based on courses held by the authors, this material will assist students and scientists studying the complex processes within atoms and ions in different kinds of plasmas by developing relatively simple but highly effective models. Considerable attention is paid to a number of qualitative models that deliver physical transparency, while extensive tables and formulas promote the practical and useful application of complex theories and provide effective tools for non-specialist readers.
Plasmas comprise more than 99% of the observable universe. They are important in many technologies and are key potential sources for fusion power. Atomic and radiation physics is critical for the diagnosis, observation and simulation of astrophysical and laboratory plasmas, and plasma physicists working in a range of areas from astrophysics, magnetic fusion, and inertial fusion utilise atomic and radiation physics to interpret measurements. This text develops the physics of emission, absorption and interaction of light in astrophysics and in laboratory plasmas from first principles using the physics of various fields of study including quantum mechanics, electricity and magnetism, and statistical physics. Linking undergraduate level atomic and radiation physics with the advanced material required for postgraduate study and research, this text adopts a highly pedagogical approach and includes numerous exercises within each chapter for students to reinforce their understanding of the key concepts.
This concise book provides the necessary background to allow interested readers to launch original research projects on the subject matter. Currently, this material is not available from one single source, and is either spread out over numerous journal publications, or covered in long and technical monographs. At the core of this book lies the sum rule approach to obtain analytic results in Quantum Chromodynamics (QCD), the current theory of strong interactions among quarks and gluons. This method fully complements Lattice QCD, the corresponding computational approach based on discretizing QCD on a space-time lattice. Applications include standard determinations of hadronic particle properties with extensions to finite temperature and density, and possibly involving the presence of extreme magnetic fields. The latter cases include stellar objects (e.g. neutron stars and magnetars) as well as high-energy proton-proton and heavy-ion collisions. Further topics concern the determination of the fundamental parameters of QCD, e.g. quark masses and the quark-gluon couplings, the hadronic contribution to the anomalous magnetic moment of the muon, and electromagnetic coupling at the the W-boson mass scale.
This textbook on optics provides an introduction to key concepts of wave optics and light propagation. It uniquely makes extensive use of Fourier methods and the angular-spectrum approach, especially to provide a unified approach to Fraunhofer and Fresnel diffraction. A recurring theme is that simple building blocks such as plane and spherical waves can be summed to construct useful solutions. The text pays particular attention to analysing topics in contemporary optics such as propagation, dispersion, laser beams and wave guides, apodisation, tightly-focused vector fields, unconventional polarization states, and light-matter interactions. Throughout the text, the principles are applied through worked examples, and the book is copiously illustrated with more than 240 figures. The 200 end-of-chapter exercises offer further opportunities for testing the reader's understanding.
The application of mathematical models to molecules has now reached maturity. Scientists as diverse as astrophysicists, biologists, chemists, materials scientists and zoologists can reach for their PC, Mac or laptop to model molecular phenomena of unbelievable complexity.
How the scientific community overlooked, ignored, and denied the catastrophic fallout of decades of nuclear testing in the American West In December of 1950, President Harry Truman gave authorization for the Atomic Energy Commission to conduct weapons tests and experiments on a section of a Nevada gunnery range. Over the next eleven years, more than a hundred detonations were conducted at the Nevada Test Site, and radioactive debris dispersed across the communities just downwind and through much of the country. In this important work, James C. Rice tells the hidden story of nuclear weapons testing and the negligence of the US government in protecting public health. Downwind of the Atomic State focuses on the key decisions and events shaping the Commission's mismanagement of radiological contamination in the region, specifically on how the risks of fallout were defined and redefined, or, importantly, not defined at all, owing to organizational mistakes and the impetus to keep atomic testing going at all costs. Rice shows that although Atomic Energy Commission officials understood open-air detonations injected radioactive debris into the atmosphere, they did not understand, or seem to care, that the radioactivity would irrevocably contaminate these communities. The history of the atomic Southwest should be a wake-up call to everyone living in a world replete with large, complex organizations managing risky technological systems. The legacy of open-air detonations in Nevada pushes us to ask about the kinds of risks we are unwittingly living under today. What risks are we being exposed to by large organizations under the guise of security and science?
This is the fifth volume in a series of Lecture Notes based on the highly successful Euro Summer School on Exotic Beams. The aim of these notes is to provide a thorough introduction to radioactive ion-beam physics at the level of graduate students and young postdocs starting out in the field. Each volume covers a range of topics from nuclear theory to experiment and applications. Vol I has been published as LNP 651, Vol II as LNP 700, Vol. III as LNP 764 and Vol. IV as LNP 879.
The aim of this book is to present highly accurate and extensive theoretical Atomic data and to give a survey of selected calculational methods for atomic physics, used to obtain these data. The book presents the results of calculations of cross sections and probabilities of a broad variety of atomic processes with participation of photons and electrons, namely on photoabsorption, electron scattering and accompanying effects. Included are data for photoabsorption and electron scattering cross-sections and probabilities of vacancy decay formed for a large number of atoms and ions. Attention is also given to photoionization and vacancy decay in endohedrals and to positron-atom scattering. The book is richly illustrated. The methods used are one-electron Hartree-Fock and the technique of Feynman diagrams that permits to include many-electron correlations. This is done in the frames of the Random Phase approximation with exchange and the many-body perturbation theory. Newly obtained and previously collected atomic data are presented. The atomic data are useful for investigating the electronic structure and physical processes in solids and liquids, molecules and clusters, astronomical objects, solar and planet atmospheres and atomic nucleus. Deep understanding of chemical reactions and processes is reached by deep and accurate knowledge of atomic structure and processes with participation of atoms. This book is useful for theorists performing research in different domains of contemporary physics, chemistry and biology, technologists working on production of new materials and for experimentalists performing research in the field of photon and electron interaction with atoms, molecules, solid bodies and liquids.
Advances in laser technology over the last 10-15 years have stimulated study of the active control of quantum molecular dynamics. Lasers may used to generate external fields of varying intensity, phases, and spectral content, which then are used to alter the molecular dynamics of a system so as to generate more of a particular product. Control of reactions at this microscopic level is one of the hot areas of research in chemical physics. This book describes the current status of the theory of optical control of molecular dynamics
Why didn't the matter in our Universe annihilate with antimatter immediately after its creation? The study of CP violation may help to answer this fundamental question. This book presents theoretical tools necessary to understand this phenomenon. Reflecting the explosion of new results over the last decade, this second edition has been substantially expanded. It introduces charge conjugation, parity and time reversal, before describing the Kobayashi-Maskawa (KM) theory for CP violation and our understanding of CP violation in kaon decays. It reveals how the discovery of B mesons has provided a new laboratory to study CP violation with KM theory predicting large asymmetries, and discusses how these predictions have been confirmed since the first edition of this book. Later chapters describe the search for a new theory of nature's fundamental dynamics. This book is suitable for researchers in high energy, atomic and nuclear physics, and the history and philosophy of science. |
