Noncovalent Forces
by Steve ScheinerComputational methods, and in particular quantum chemistry, have taken the lead in our growing understanding of noncovalent forces, as well as in their categorization. This volume describes the current state of the art in terms of what we now know, and the current questions requiring answers in the future. Topics range from very strong (ionic) to very weak (CH--π) interactions. In the intermediate regime, forces to be considered are H-bonds, particularly CH--O and OH--metal, halogen, chalcogen, pnicogen and tetrel bonds, aromatic stacking, dihydrogen bonds, and those involving radicals. Applications include drug development and predictions of crystal structure.
Noncovalent Functionalization of Carbon Nanotubes
by Claudia BackesIn this thesis, Claudia Backes guides the reader through her multidisciplinary research into the non-covalent functionalization of carbon nanotubes in water. Although one of the most remarkable materials of the 21st century, carbon nanotubes often have limited application because of their intrinsically low solubility and polydispersity. The author shows that rational surfactant design is a powerful tool for chemists because it can unmask the key to solubilization and allow us to tailor nanotube surface and optical properties in a fully reversible fashion. Aspects of organic, physical and analytical chemistry, as well as colloidal sciences are covered in this outstanding work which brings us one step closer to exploiting this super-material to its full potential.
Nondestructive Assay of Nuclear Materials for Safeguards and Security
by Martyn T. Swinhoe William H. Geist Peter A. SantiThis open access book describes the nondestructive assay techniques that are used for the measurement of nuclear material (primarily uranium and plutonium) for nuclear material accountancy purposes. It is a substantial revision to the so-called PANDA manual that has been a standard reference since its publication in 1991. The book covers the origin and interactions of gamma rays and neutrons as they affect nuclear measurements and also describes the theory and practice of calorimetry. The book gives a description of many instruments based on these techniques that are applied in the field. Although the basic physics has not changed since PANDA was first published, the last thirty years have seen many advances in analysis methods, instrumentation, and applications. The basic descriptions of the origin and interactions of radiation have been updated and include newer references. There have been extensive revisions of the description of gamma detection methods, attenuation correction procedures, and analysis methods, including for the measurement of uranium enrichment and the determination of plutonium isotopic composition. Extensive revisions and additions have also been made to the description of neutron detectors and to the explanation of neutron coincidence techniques. The chapter on neutron multiplicity techniques is a new addition to this edition. The applications of gamma and neutron techniques have been completely overhauled to remove obsolete systems and to include many current applications. The values of, and references to, nuclear data have been updated. This updated edition is an essential reference for academic researchers and practitioners in the field. This is an open access book.
Nondestructive Biomarkers in Vertebrates
by Cristina Fossi Claudio LeonzioNondestructive Biomarkers in Vertebrates presents an innovative approach for hazard assessment in vertebrates based on nondestructive rather than destructive methods. The book reviews the state of the art and defines the development and validation procedure of this new strategy. Biological materials, such as blood samples, epithelial tissue, eggs, feathers, and feces that can be obtained without stress or damage to the animal are suggested. Certain traditional studies (blood esterases, blood chemistry, mixed function oxidases, porphyrins, DNA damage, and cytological changes) can be performed on these specimens, along with new tests requiring only very small samples. This approach is developed to benefit protected, threatened species whose existence cannot be further jeopardized by the use of destructive methods. This volume will be particularly useful to ecotoxicologists, wildlife protection personnel, environmental consultants, and conservationist organizations.

Nonequilibrium Dynamics of Collective Excitations in Quantum Materials (Springer Theses)
by Edoardo BaldiniThis book studies the dynamics of fundamental collective excitations in quantum materials, focusing on the use of state-of-the-art ultrafast broadband optical spectroscopy. Collective behaviour in solids lies at the origin of several cooperative phenomena that can lead to profound transformations, instabilities and phase transitions. Revealing the dynamics of collective excitations is a topic of pivotal importance in contemporary condensed matter physics, as it provides information on the strength and spatial distribution of interactions and correlation. The experimental framework explored in this book relies on setting a material out-of-equilibrium by an ultrashort laser pulse and monitoring the photo-induced changes in its optical properties over a broad spectral region in the visible or deep-ultraviolet. Collective excitations (e.g. plasmons, excitons, phonons…) emerge either in the frequency domain as spectral features across the probed range, or in the time domain as coherent modes triggered by the pump pulse. Mapping the temporal evolution of these collective excitations provides access to the hierarchy of low-energy phenomena occurring in the solid during its path towards thermodynamic equilibrium. This methodology is used to investigate a number of strongly interacting and correlated materials with an increasing degree of internal complexity beyond conventional band theory.

Nonequilibrium Many-Body Theory of Quantum Systems
by Gianluca Stefanucci Robert Van LeeuwenThe Green's function method is one of the most powerful and versatile formalisms in physics, and its nonequilibrium version has proved invaluable in many research fields. This book provides a unique, self-contained introduction to nonequilibrium many-body theory. Starting with basic quantum mechanics, the authors introduce the equilibrium and nonequilibrium Green's function formalisms within a unified framework called the contour formalism. The physical content of the contour Green's functions and the diagrammatic expansions are explained with a focus on the time-dependent aspect. Every result is derived step-by-step, critically discussed and then applied to different physical systems, ranging from molecules and nanostructures to metals and insulators. With an abundance of illustrative examples, this accessible book is ideal for graduate students and researchers who are interested in excited state properties of matter and nonequilibrium physics.
Nonequilibrium Molecular Dynamics
by Billy D. Todd Peter J. DaivisWritten by two specialists with over twenty-five years of experience in the field, this valuable text presents a wide range of topics within the growing field of nonequilibrium molecular dynamics (NEMD). It introduces theories which are fundamental to the field - namely, nonequilibrium statistical mechanics and nonequilibrium thermodynamics - and provides state-of-the-art algorithms and advice for designing reliable NEMD code, as well as examining applications for both atomic and molecular fluids. It discusses homogenous and inhomogenous flows and pays considerable attention to highly confined fluids, such as nanofluidics. In addition to statistical mechanics and thermodynamics, the book covers the themes of temperature and thermodynamic fluxes and their computation, the theory and algorithms for homogenous shear and elongational flows, response theory and its applications, heat and mass transport algorithms, applications in molecular rheology, highly confined fluids (nanofluidics), the phenomenon of slip and how to compute it from basic microscopic principles, and generalized hydrodynamics.
Nonequilibrium Phase Transitions in Driven Vortex Matter: The Reversible-Irreversible Transition, Dynamical Ordering, and Kibble-Zurek Mechanism (Springer Theses)
by Shun MaegochiThis book presents experimental studies of nonequilibrium phase transitions induced by ac and dc forces in collectively interacting systems—a superconducting vortex system with random pinning. It first shows that a phase transition from reversible to irreversible flow occurs by increasing vortex density as well as amplitude of ac shear, which is indicative of the universality of the reversible-irreversible transition. Two distinct flow regimes are also found in the reversible phase. Next, the book presents new methods for dc driven experiments—transverse mode-locking and transverse current-voltage measurements—and provides convincing evidence of the second-order dynamical transition from disordered plastic to anisotropically ordered smectic flow. Lastly it reports on the first experimental demonstration of the Kibble-Zurek mechanism for the nonequilibrium phase transition.The experimental results indicate that both the reversible-irreversible transition and the dynamical ordering transition belong to the directed percolation universality class which is one of the fundamental classes of nonequilibrium phase transitions. Hence, the findings will be generalized to other nonequilibrium systems and stimulate research on nonequilibrium physics.
Nonequilibrium Processes in Catalysis
by Oleg V. KrylovNonequilibrium Processes in Catalysis presents modern ideas and experimental data (e.g., molecular beams, laser technique) on adsorption and catalysis, the mechanism of energy exchange in the processes of particles interaction with a surface, and the lifetimes of excited particles on a surface. Previously unpublished theoretical information regarding the principle of chemoenergetical stimulation accounting for the acceleration of one reaction at the expense of reactant excitation in another is provided, and new ideas about nonequilibrium surface diffusion are explored. Examples of the formation of nonequilibrium dissipative structures in catalysis are presented, including auto-oscillations, auto-waves, multiplicity of kinetic regimes, nonequilibrium phase transition, and decelerated electron exchange between solid and adsorbed species. The book also describes new experimental methods for studying nonequilibrium and quick processes in catalysis. Nonequilibrium Processes in Catalysis will benefit physicists involved with surface science, chemists involved with adsorption and catalysis, engineers, vacuum scientists, physical chemists, materials chemists, students, and others interested in these processes.
Nonequilibrium Statistical Mechanics of Heterogeneous Fluid Systems
by Andrei G. BashkirovThere is a wide variety of heterogeneous fluid systems that possess interphase surfaces. This monograph is devoted to pioneering studies in nonequilibrium statistical mechanics of such systems. Starting from the Liouville equation, the equations of surface hydrodynamics are derived with allowance for discontinuities of thermodynamic parameters of interphase boundaries. Brownian motion of a large solid particle in a fluid and nucleation are treated as results of fluctuations of flows across particle surfaces. With the use of the Gibbs method, a shock wave in a gas is considered as a sort of an interphase surface, and the surface tension of a shock front is introduced for the first time.
Nonequilibrium Statistical Mechanics: An Introduction with Applications
by Biman BagchiNonequilibrium statistical mechanics (NESM), practically synonymous with time-dependent statistical mechanics (TDSM), is a beautiful and profound subject, vast in scope, diverse in applications, and indispensable in understanding the changing natural phenomena we encounter in the physical, chemical and biological world. Although time dependent phenomena have been studied from antiquity, the modern subject, the nonequilibrium statistical mechanics, has its genesis in Boltzmann’s 1872 classic paper that aimed at extending Maxwell’s kinetic theory of gases by including intermolecular interactions. Subsequent development of the subject drew upon the seminal work of Einstein and Langevin on Brownian motion, Rayleigh and Stokes on hydrodynamics, and on the works of Onsager, Prigogine, Kramers, Kubo, Mori, and Zwanzig. One major goal of this book is to develop and present NESM in an organized fashion so that students can appreciate and understand the flow of the subject from postulates to practical uses. This book takes the students on a journey from fundamentals to applications, mostly using simple mathematics, and fundamental concepts. With the advent of computers and computational packages and techniques, a deep intuitive understanding can allow the students to tackle fairly complex problems, like proteins in lipid membranes or solvation of ions in electrolytes used in batteries. The subject is still evolving rapidly, with forays into complex biological events, and materials science. Nonequilibrium Statistical Mechanics: An Introduction with Applications is, thus, an introductory text that aims to provide students with a background and skill essential to study and understand time-dependent (relaxation) phenomena. It will allow students to calculate transport properties like diffusion and conductivity. The book also teaches the methods to calculate reaction rate on a multi-dimensional energy surface, in another such application. For a beginner in the field, especially for one with an aim to study chemistry and biology, and also physics, one major difficulty faced is a lack of organization of the available study material. Since NESM is a vast subject with many different theoretical tools, the above poses a problem. This book lays the foundations towards understanding time- dependent phenomena in a simple and systematic fashion. It is accessible to students and researchers who have basic training in physics and mathematics. The book can be used to teach advanced undergraduates. Some involved topics, like the projection operator technique and mode coupling theory, are more suitable for Ph.D. level.
Nonequilibrium Statistical Physics: A Modern Perspective
by Roberto Livi Paolo PolitiStatistical mechanics has been proven to be successful at describing physical systems at thermodynamic equilibrium. Since most natural phenomena occur in nonequilibrium conditions, the present challenge is to find suitable physical approaches for such conditions: this book provides a pedagogical pathway that explores various perspectives. The use of clear language, and explanatory figures and diagrams to describe models, simulations and experimental findings makes the book a valuable resource for undergraduate and graduate students, and also for lecturers organizing teaching at varying levels of experience in the field. Written in three parts, it covers basic and traditional concepts of nonequilibrium physics, modern aspects concerning nonequilibrium phase transitions, and application-orientated topics from a modern perspective. A broad range of topics is covered, including Langevin equations, Levy processes, directed percolation, kinetic roughening and pattern formation.
Nonequilibrium and Irreversibility (Lecture Notes in Physics #1040)
by Giovanni GallavottiThis 2nd edition of the book focuses on the properties of stationary states in chaotic systems of particles or fluids, setting aside the theory of how these states are achieved. The second edition has been thoroughly revised and includes numerous corrections. It incorporates recent findings, with particular emphasis on the equivalence between irreversible and reversible equations. The ongoing debate over reversibility and irreversible behavior is frequently discussed. The book seeks to unify the study of stationary nonequilibrium states with that of equilibrium states, using the paradigm offered by the simplest chaotic systems, specifically Anosov systems. The book begins by exploring the time-invariant distributions relevant to physics. A distinctive feature of this work is its historical approach. To clarify foundational issues, the author analyzes the works of pioneering figures like Boltzmann, Clausius, and Maxwell, including translated excerpts of key historical documents. Additionally, the author establishes a close connection between the treatment of irreversible phenomena in statistical mechanics and the theory of chaotic systems, particularly at and beyond the onset of turbulence, as developed by Sinai, Ruelle, and Bowen (SRB) and others. Arguments are presented to strongly support the perspective that stationary states, whether in equilibrium or not, can be described in a unified framework. The book offers extensive coverage of contemporary research, presented in sufficient detail to give advanced students a sense of the ongoing research directions in this dynamic field. Proofs of theorems are generally limited to heuristic outlines, favoring the presentation of concepts and providing references for further study, thereby avoiding an overload of technical detail in the main text.
Nonhuman DNA Typing: Theory and Casework Applications (International Forensic Science and Investigation)
by Heather Miller CoyleThe association of a suspect with the victim or crime scene through DNA evidence is one of the most powerful statements of complicity in a crime imaginable. No category of evidence has ever had the complete capacity to convict or exonerate an accused so absolutely in the eyes of the public. With the discriminatory powers of DNA and the variety of D
Nonhuman Humanitarians: Animal Interventions in Global Politics
by Benjamin MeichesExamining the appearance of nonhuman animals laboring alongside humans in humanitarian operations Both critical and mainstream scholarly work on humanitarianism have largely been framed from anthropocentric perspectives highlighting humanity as the rationale for providing care to others. In Nonhuman Humanitarians, Benjamin Meiches explores the role of animals laboring alongside humans in humanitarian operations, generating new ethical possibilities of care in humanitarian practice.Nonhuman Humanitarians examines how these animals not only improve specific practices of humanitarian aid but have started to transform the basic tenets of humanitarianism. Analyzing case studies of mine-clearance dogs, milk-producing cows and goats, and disease-identifying rats, Nonhuman Humanitarians ultimately argues that nonhuman animal contributions problematize foundational assumptions about the emotional and rational capacities of humanitarian actors as well as the ethical focus on human suffering that defines humanitarianism.Meiches reveals that by integrating nonhuman animals into humanitarian practice, several humanitarian organizations have effectively demonstrated that care, compassion, and creativity are creaturely rather than human and that responses to suffering and injustice do not—and cannot—stop at the boundaries of the human.
Nonhuman Primate Models For Human Diseases
by W. Richard DukelowWhile research has enabled us to better understand the nonhuman primates, they have repaid that by repaid that by providing medical scientists with important tools for the study of human biomedical problems. This book is about those research tools. The book was designed by identifying areas of human medical research that are under intensive research study today. Authors were then selected based on their expertise at using nonhuman primates as models for the human condition. Each was asked to use as comparative an approach as models for the human condition. Each was asked to use a comparative an approach as possible, to provide the reader with knowledge relating to the usefulness of various nonhuman primate species to each specific research area.
