Описание: Complex liquids constitute a basic element in modern materials science; their significant features include self-assembly, mesoscale structures, complex dynamics, unusual phases and enormous sensitivity to perturbations. Understanding their nature and properties are a great challenge to modern materials science that demands novel approaches. This book focuses on nonlinear dielectric phenomena, particularly on nonlinear dielectric spectroscopy (NDS), which may be considered a possible successor to broadband dielectric spectroscopy (BDS). NDS phenomena directly coupled to mesoscale heterogeneity fluctuations, so information obtained in this way is basically complementary to BDS tests. The book also discusses the application of NDS in a set of complex liquid systems: glassy liquids, liquid crystals, liquids with critical point phenomena, and bio-relevant liquids. The complementary application of NDS and BDS may allow the discovery of universal patterns for the whole category of complex liquids. Written by specialists in the field of nonlinear dielectric studies, theoreticians and experimentalists, ranging from solid state physics to biophysics, the book is organized so that it can serve as a basic textbook for a non-experienced reader.
Описание: Time-Resolved Spectroscopy in Complex Liquids introduces current state-of-the-art techniques in the study of complex dynamical problems in liquid phases. With a unique focus on the experimental aspects applied to complex liquids, this volume provides an excellent overview into the quickly emerging field of soft-matter science. Researchers and engineers will find a comprehensive review of current non-linear spectroscopic and optical Kerr effect techniques, in addition to an in-depth look into relaxation dynamics in complex liquids. This volume offers current experimental findings in transient grating spectroscopy and their application to viscoelastic phenomena in glass-formers, dynamics of confined liquid-crystals, and a time-resolved analysis of the host-quest interactions of dye molecules in liquid-crystal matter.Time-Resolved Spectroscopy in Complex Liquids provides a cohesive introduction suitable for individuals involved in this emerging field, complete with the latest experimental procedures of complex liquids.

Описание: This book reviews the present knowledge of collision-induced absorption of infrared radiation in the dense, common gases. Following a brief introduction and review of essential background information, such as dipole radiation, molecular collisions and interactions, numerous experimental results for the absorption spectra of dense gases are presented. Other chapters review the causes and properties of dipole moments induced by molecular interactions, the theory of collision-induced absorption in monatomic gas mixtures and in molecular gases and mixtures. The final chapter discusses related phenomena and the important applications in astrophysics. Throughout the book, the emphasis is on the absorption by binary molecular complexes, but the onset of many-body effects, such as the ternary contributions and the intercollisional process, are also considered. The volume is meant to be a practical guide and sourcebook for the researcher interested in the spectroscopy of dense, neutral fluids. This edition includes a new appendix reviewing recent work.

Описание: The understanding of these effects requires a theoretical description of the orientation and alignment parameters of the target atoms, of the forma- tion of resonances, of the influence of electron-exchange processes, and of the relativistic interactions inside the atom and between projectile and target.

Описание: This book presents an up-to-date overview of reflectometers used for optical spectroscopy of various kinds of liquids, ranging from well-known transparent liquids to "pathological" industrial liquids. The book reviews and explains basic materials for anyone wanting to get to know the theory, spectral analysis and modern devices needed for the measurement of refractive index and absorption of liquids. Moreover, the book gives an introduction to reflectivity from optically nonlinear liquids such as liquids containing nanoparticles. This latter topic is important in modern nano-sciences.
Описание: This is the first book dedicated to the glass transition since this concept became recognized as a distinct and independent field of investigation. The glass transition is a synonym for relaxation and dynamics in complex disordered systems, especially in liquids. It embraces time-scales ranging from picoseconds to years. The book describes and interrelates the following processes: cooperative alpha processes in a cold liquid, structural relaxation in the glass near Tg, the Johari-Goldstein beta process, the Williams-GГ¶tze process in a warm liquid, fast nonactivated cage rattling and boson peak, and ultraslow Fischer modes. By describing the salient facts, explaining and discussing the fundamentals, the author attempts to introduce a unifying concept for the entire material. The formulas, diagrams and references are carefully selected to illustrate the main current ideas about the glass transition.
Описание: This book is an introduction to the application of computer simulation and theory in the study of the interaction of energetic particles (< 1 eV to the MeV range) with solid surfaces. The authors describe methods which are applicable both to hard collisions between nuclear cores of atoms down to soft interactions, where chemical effects or long-range forces dominate. In surface science, potential applications include surface atomic structure determination using ion scattering spectroscopy or element analysis using SIMS or other techniques that involve depth profiling. Industrial applications include optical or hard coating deposition, ion implantation in semiconductor device manufacture or nanotechnology. Plasma-sidewall interaction in fusion devices may also be studied using the techniques described. This book will be of interest to graduate students and researchers, both academic and industrial, in surface science, semiconductor engineering, thin-film deposition and particle-surface interactions, in departments of physics, chemistry and electrical engineering.
Описание: This book illustrates how potential flows enter into the general theory of motions of viscous and viscoelastic fluids. Traditionally, the theory of potential flow is presented as a subject called ‘potential flow of an inviscid fluid’; when the fluid is incompressible these fluids are, curiously, said to be ‘perfect’ or ‘ideal’. This type of presentation is widespread; it can be found in every book on fluid mechanics, but it is flawed. It is never necessary and typically not useful to put the viscosity of fluids in potential (irrotational) flow to zero. The dimensionless description of potential flows of fluids with a nonzero viscosity depends on the Reynolds number, and the theory of potential flow of an inviscid fluid can be said to rise as the Reynolds number tends to infinity. The theory given here can be described as the theory of potential flows at finite and even small Reynolds numbers.
Описание: This work seeks to present a unified formulation from first principles of the Hamiltonian and statistical mechanics of metallic and insulating crystals, amorphous
solids, and liquids. Extensive comparison of theory and experiment provides an understanding of the statistical properties of phonons, electrons, and phonon-phonon and
electron-phonon interactions in elemental crystals and liquids. Questions are posed along the following lines: what is the "best" theory for a given property? How accurate is a good
theory? What information is gained by a comparison of theory and experiment? How accurate is a good experiment?
