Recent Advances in Broadband Dielectric Spectroscopy by Yuri P. Kalmykov Pdf
This volume considers experimental and theoretical dielectric studies of the structure and dynamics of complex systems. Complex systems constitute an almost universal class of materials including associated liquids, polymers, biomolecules, colloids, porous materials, doped ferroelectric crystals, nanomaterials, etc. These systems are characterized by a new "mesoscopic" length scale, intermediate between molecular and macroscopic. The mesoscopic structures of complex systems typically arise from fluctuations or competing interactions and exhibit a rich variety of static and dynamic behaviour. This growing field is interdisciplinary; it complements solid state and statistical physics, and overlaps considerably with chemistry, chemical engineering, materials science, and biology. A common theme in complex systems is that while such materials are disordered on the molecular scale and homogeneous on the macroscopic scale, they usually possess a certain degree of order on an intermediate, or mesoscopic, scale due to the delicate balance of interaction and thermal effects. In the present Volume it is shown how the dielectric spectroscopy studies of complex systems can be applied to determine both their structures and dynamics.
Crystallization as Studied by Broadband Dielectric Spectroscopy by Tiberio A. Ezquerra,Aurora Nogales Pdf
This book presents new approaches that offer a better characterization of the interrelationship between crystalline and amorphous phases. In recent years, the use of dielectric spectroscopy has significantly improved our understanding of crystallization. The combination of modern scattering methods, using either synchrotron light or neutrons and infrared spectroscopy with dielectrics, is now helping to reveal modifications of both crystalline and amorphous phases. In turn, this yields insights into the underlying physics of the crystallization process in various materials, e.g. polymers, liquid crystals and diverse liquids. The book offers an excellent introduction to a valuable application of dielectric spectroscopy, and a helpful guide for every scientist who wants to study crystallization processes by means of dielectric spectroscopy.
Dielectric Spectroscopy of Electronic Materials by Yuriy Poplavko Pdf
Dielectric Spectroscopy of Electronic Materials: Applied Physics of Dielectrics incorporates the results of four decades of research and applications of dielectric spectroscopy for solids, mostly for the investigation of materials used in electronics. The book differs from others by more detailed analysis of the features of dielectric spectra conditioned by specific mechanisms of electrical polarization and conductivity. Some original methods are presented in the simulation of frequency distributions (relaxers and oscillators), with methods proposed for various ferroelectrics frequency-temperature dielectric spectra. Also described are original methods for ferroelectrics on microwaves investigation, including the features of thin films study. The book is not burdened by complex mathematical proofs and should help readers quickly understand how to apply dielectric spectroscopy methods to their own research problems. More advanced readers may also find this book valuable as a review of the key concepts and latest advances on the topics presented. Introduces critical material characterization techniques by an expert with more than 40 years of experience in dielectric spectroscopy Reviews advances in dielectric spectroscopy methods to enable advances such as the miniaturization of electronics at the nanoscale Provides an overview of polarization mechanisms utilizing different models (i.e., oscillator and relaxation)
The Scaling of Relaxation Processes by Friedrich Kremer,Alois Loidl Pdf
The dielectric properties especially of glassy materials are nowadays explored at widely varying temperatures and pressures without any gap in the spectral range from μHz up to the Infrared, thus covering typically 20 decades or more. This extraordinary span enables to trace the scaling and the mutual interactions of relaxation processes in detail, e.g. the dynamic glass transition and secondary relaxations, but as well far infrared vibrations, like the Boson peak. Additionally the evolution of intra-molecular interactions in the course of the dynamic glass transition is also well explored by (Fourier Transform) Infrared Spectroscopy. This volume within 'Advances in Dielectrics' summarizes this knowledge and discusses it with respect to the existing and often competing theoretical concepts.

Broadband Dielectric Spectroscopy in Neat and Binary Molecular Glass Formers by Thomas Blochowicz Pdf
Neat and binary molecular glass formers are investigated by means of broadband dielectric spectroscopy with the aim of gaining a systematic understanding of the molecular slowing down, which is characteristic for the glass transition. By combining frequency and time domain techniques a dynamic range from 10-6, Hz up to 109, Hz is covered. Particular attention is drawn to the fact that different types of secondary relaxations may appear during the process of supercooling. In certain simple glass formers such secondary processes are clearly of intermolecular origin, and it turns out that in mixtures of small and large molecules secondary relaxations can be systematically altered by changing the concentration of the constituents. Thus, the relation between different types of secondary processes may be clarified. It is typical of glass forming substances that the decay of orientational correlations is non-exponential, and, correspondingly, the dielectric loss spectra are broadened as compared to a simple Debye-like relaxation process. The latter effect is particularly pronounced in binary glass formers, and one aim of the present work is to provide and apply an appropriate tool for a line shape analysis of the relaxation spectra in both neat end binary systems. On the other hand, the nature of spectral broadening is investigated by means of non-resonant dielectric hole burning, which allows to distinguish between heterogeneous and homogeneous dynamics in a system. It turns out that inbinary glass formers dynamic heterogeneities are particularly pronounced and that the effects of dielectric hole burning in both neat and binary systems are very well described within the framework of a model of selective local heating.

Dielectric Relaxation in Biological Systems by Valerica Raicu,Yuri Feldman Pdf
The study of dielectric properties of biological systems and their components is important not only for fundamental scientific knowledge but also for its applications in medicine, biology, and biotechnology. The associated technique - known as dielectric spectroscopy - has enabled researchers to quickly and accurately acquire time- or frequency-spectra of permittivity and conductivity and permitted the derivation and testing of realistic electrical models for cells and organelles. This text covers the theoretical basis and practical aspects of the study of dielectric properties of biological systems, such as water, electrolyte and polyelectrolytes, solutions of biological macromolecules, cells suspensions and cellular systems. The authors' combined efforts provide a comprehensive and cohesive book that takes advantage of the expertise of multiple scientists involved in cutting-edge research in the specific sub-fields of bio-dielectric spectroscopy while maintaining its self-consistency through numerous discussions. The first six chapters cover theoretical, methodological and experimental aspects of relaxation and dispersion in biological dielectrics at molecular, cellular and cellular aggregate level. Applications are presented in the following chapters which are organized in the order of increased complexity, beginning with pure water, amino acids and proteins, continuing with vesicles and simple cells such as erythrocytes, and then with more complex, organelle-containing cells and cellular aggregates. Due to its broad coverage, the text could be used as a reference book by researchers, and as a textbook for upper-level undergraduate classes and graduate classes in (bio) physics, medical physics, quantitative biology, and engineering.
