Electro-Chemo-Mechanical Properties of Solid Electrode Surfaces

by Masahiro Seo

This book deals with the electro-chemo-mechanical properties characteristic of and unique to solid electrode surfaces, covering interfacial electrochemistry and surface science. Electrochemical reactions such as electro-sorption, electro-deposition or film growth on a solid electrode induce changes in surface stress or film stress that lead to transformation of the surface phase or alteration of the surface film. The properties of solid electrode surfaces associated with the correlation between electrochemical and mechanical phenomena are named “electro-chemo-mechanical properties”. The book first derives the surface thermodynamics of solid electrodes as fundamentals for understanding the electro-chemo-mechanical properties. It also explains the powerful techniques for investigating the electro-chemo-mechanical properties, and reviews the arguments for derivation of surface thermodynamics of solid electrodes. Further, based on current experimental findings and theories, it discusses the importance of the contribution of surface stress to the transformation of surface phases, such as surface reconstruction and underpotential deposition in addition to the stress evolution during film growth and film reduction. Moreover, the book describes the nano-mechanical properties of solid surfaces measured by nano-indentation in relation to the electro-chemo-mechanical properties. This book makes a significant contribution to the further development of numerous fields, including electrocatalysis, materials science and corrosion science.

Electro-Chemo-Mechanics of Anodic Porous Alumina Nano-Honeycombs: Self-Ordered Growth and Actuation (Springer Theses)

by Chuan Cheng

In this thesis, real-time evolution of the nanopore channel growth and self-ordering process in anodic nanoporous alumina are simulated on the basis of an established kinetics model. The simulation results were in accordance with the experiments on the (i) growth sustainability of pore channels guided by pre-patterns; and (ii) substrate grain orientation dependence on self-ordering. In addition, a new fabrication method for the rapid synthesis of highly self-ordered nanoporous alumina is established, based on a systematic search for the self-ordering conditions in experiments. Lastly, it reports on a novel surface-charge induced strain in nanoporous alumina-aluminium foils, which indicates that nanoporous alumina can be used as a new type of actuating material in micro-actuator applications.

Electro-Chemo-Mechanics of Solids (Electronic Materials: Science & Technology)

by Sean R. Bishop Nicola H. Perry Dario Marrocchelli Brian W. Sheldon

This book brings together a collection of chapters that focus on the relationship among electrical, chemical, and mechanical properties and the study of adjusting one property through the control of another, namely, Electro-Chemo-Mechanics (ECM). The authors examine how this relationship can result in beneficial properties, such as mixed ionic and electronic conductivity, in oxides, upon oxygen deficiency or lithium insertion (electro-chemo) and/or changes in ionic and electronic mobility observed in strained systems (electro-mechano). They also consider how ECM interactions can be responsible for large stresses from non-stoichiometry induced lattice dilation (chemo-mechano). While many volumes are available devoted to the study of the origins and characteristics of electro-chemical relationships, they form the well-known field of electrochemistry, this volume is highly novel in its examination of the corresponding electro-mechanical, chemo-mechanical, and electro-chemo-mechanical relationships. The book is ideal for researchers and design engineers interested in energy storage and conversion and the electrical and mechanical properties of materials.

Electro-optic and Photorefractive Materials: Proceedings of the International School on Material Science and Technology, Erice, Italy, July 6–17, 1986 (Springer Proceedings in Physics #18)

by Peter Günter

This volume is based on lectures and contributed papers presented at the Eleventh Course of the International School of Materials Science and Tech­ nology that was held in Erice, Sicily, Italy at the Ettore Majorana Center for Scientific Culture during the period 6-17 July 1986. The subject of the course was "Electro-optic and Photorefractive Materials: Applications in Sig­ nal Processing and Phase Conjugation" . The fields of electro-optics and photorefraction have developed rapidly since the invention of lasers just over twenty-five years ago. The possibil­ of altering the optical properties of a material by electric fields or by ity optical waves is of great importance for both pure science and for practical applications such as optical signal processing, telecommunications and opti­ cal display devices. These effects allow us to manipulate (modulate, deflect) and process a given light wave. Modulation, deflection and processing of light waves by means of the electro-optic effect is of fundamental importance in fiber optic telecommuniC1. tions and sensor systems w here the light signals can be processed prior or subsequent to transmission through the fibers. Thin film electro-optic materials with suitable electrode arrays on· the surface of the wave-guiding structures result in a technology often referred to as inte­ grated optics. In principle, integrated optics devices allow miniaturization and integration of many operations onto a single chip. The photorefractive effect, defined as a photo-induced change of the in­ dices of refraction, was the other topic treated in this course.

Electro-optic Photonic Circuits: From Linear and Nonlinear Waves in Nanodisordered Photorefractive Ferroelectrics (Springer Theses)

by Giuseppe Di Domenico

This book reports new findings in the fields of nonlinear optics, quantum optics and optical microscopy. It presents the first experimental device able to transform an input Gaussian beam into a non-diffracting Bessel-like beam. The modulation mechanism, i.e. electro-optic effect, allows the device to be fast, miniaturizable and integrable into solid state arrays. Also presented is an extensive study of the superposition of Bessel beams and their propagation in turbid media, with the aim of realizing field that is both localized and non-diffracting. These findings have been implemented in a light-sheet microscope to improve the optical sectioning. From a more theoretical point of view this work also tackles the problem of whether and how a single particle is able to entangle two distant systems. The results obtained introduce fundamental limitations on the use of linear optics for quantum technology. Other chapters are dedicated to a number of experiments carried out on disordered ferroelectrics including negative intrinsic mass dynamics, ferroelectric supercrystals, rogue wave dynamics driven by enhanced disorder and first evidence of spatial optical turbulence.

Electro-Optics and Dielectrics of Macromolecules and Colloids

by Barry R. Jennings

Some seven years before Kerr's death, Larmor proposed that electric birefringence had its origin in the orientation of anisotropic molecules or elements within the apparently isotropic medium. The theory for this concept was formulated by Langevin. During the next half century, occasional measurements were made both to characterise the phenomenon and to evaluate the relevant physico-chemical parameters of pure liquids and molecular fluids. During the 1930-40 era, Staudinger and others demonstrated the existence in nature of giant molecules and colloidal particles. Since that time it has slowly but increasingly been realised that these big molecules or particles often have relatively large dipole moments, are generally anisotropic in structure and hence, in solution or suspension, give rise to significant electric birefringence signals. Furthermore, there have been three electronic innovations which have greatly eased the experimental measurement of the effect for such materials. These were the development of photomultiplier tubes for detection, of oscillo­ scope~ for display and of high voltage generators developing bursts or pulses of potential difference. The last mentioned enable the experi­ menter to study the Kerr effect not only for its amplitude but also in the time domain. The rates of molecular response to the switching of the electric field lead directly to information on the size and geo­ metry of the constituent molecules and particles in a dilute solution or suspension.

Electro-Osmosis of Polymer Solutions: Linear and Nonlinear Behavior (Springer Theses)

by Yuki Uematsu

This thesis focuses on the theoretical description of electro-osmosis of polymer solutions. In particular, it emphasizes the importance of considering non-uniform profiles of the solution viscosity and polymer concentration near a solid surface. The thesis begins with an introduction to fundamental theories and experimental observations for beginners in this field, concerning electrolyte solutions, electric double layers, and electrokinetics. In Chapter 2, the author discusses the linear response of electro-osmotic flow with respect to applied electric fields in aqueous polyelectrolyte solutions, and predicts a possibility of flow reversal caused by oppositely charged polyelectrolytes adsorbed on a charged surface. In Chapter 3, the author extends the discussion to non-linear electro-osmotic flow driven by applied electric fields in neutral polymer solutions. The dynamics of polymers are modeled and simulated using Brownian dynamics and kinetic theory. Finally, the thesis is summarized in Chapter 4. The introduction provides a comprehensive review of electrokinetics for graduate students and researchers interested in soft matter physics. An additional attraction is that readers can effectively learn various theoretical approaches to electro-osmosis.

Electroacoustic Waves in Piezoelectric Layered Composites (Advanced Structured Materials #182)

by Ara Sergey Avetisyan

This book deals concisely and coherently with various issues related to electroacoustic waves in piezoelectric layered composites.Starting with the basic linear equations and relations of electromagnet elasticity of homogeneous anisotropic piezoelectric media, the book considers the conditions for possible field or partial conjugation of physical and mechanical fields at the junction of two homogeneous media with geometrically homogeneous surfaces. The variety of electromechanical boundary conditions and the separation of plane and anti-plane fields of elastic deformation in homogeneous piezoelectric crystals are discussed.Then, the statements of the electroacoustic problem in piezo textures are studied and a layered piecewise-homogeneous piezoelectric waveguide is introduced, with non-acoustic contact between different piezoelectric layers.Non-acoustic contact between different piezoelectric layers can lead to the propagation of a hybrid of electroactive waves of plane and anti-plane elastic deformations.In the last part of the book, the problem of controlling electroacoustic waves in a waveguide is formulated. A method for solving problems of control of electroacoustic waves by non-contact surface action is proposed.

Electroacoustical Reference Data

by John Eargle

The need for a general collection of electroacoustical reference and design data in graphical form has been felt by acousticians and engineers for some time. This type of data can otherwise only be found in a collection of handbooks. Therefore, it is the author's intention that this book serve as a single source for many electroacoustical reference and system design requirements. In form, the volume closely resembles Frank Massa's Acoustic Design Charts, a handy book dating from 1942 that has long been out of print. The basic format of Massa's book has been followed here: For each entry, graphical data are presented on the right page, while text, examples, and refer­ ences appear on the left page. In this manner, the user can solve a given problem without thumbing from one page to the next. All graphs and charts have been scaled for ease in data entry and reading. The book is divided into the following sections: A. General Acoustical Relationships. This section covers the behavior of sound transmis­ sion in reverberant and free fields, sound absorption and diffraction, and directional characteris­ tics of basic sound radiators. B. Loudspeakers. Loudspeakers are discussed in terms of basic relationships regarding cone excursion, sensitivity, efficiency, and directivity index, power ratings, and architectural layout. c. Microphones. The topics in this section include microphone sensitivity and noise rating, analysis of directional properties, stereo microphone array characteristics, proximity effects, and boundary conditions. D. Signal Transmission.

Electroactive Polymer Electrochemistry: Part 2: Methods and Applications

by Michael Lyons

The development of "tailormade" electrode surfaces using electroactive polymer films has been one of the most active and exciting areas of electrochemistry over the last 15 years. The properties of these materials have been examined by a wide range of scientists from a variety of perspectives, and now electroactive polymer research is considered to be a reasonably mature area of research endeavor. Much is now understood about the fundamental mechanism of conduction in these materials. A wide range of electrochemical techniques may be used to probe the conductivity processes in these materials, and more recently, a number of in situ spectroscopic techniques have been used to further elucidate the structure of these materials. The in situ spectroscopies and allied techniques have also been used to obtain correlations between structure and redox activity. The applications found for electroactive polymers are many and varied, and range from thin film amperometric chemical and biological sensors, electrocatalytic systems, drug delivery devices, and advanced battery systems through to molecular electronic devices. The research literature on electroactive polymers is truly enormous and can daunt even the most hardened researcher. The vast quantity of material reported in the literature can also intimidate beginning graduate students. Hence the present book. The original idea for this book arose as a result of a series of lectures on chemically modified eiectrodes and electroactive polymers given by the writer to final-year undergraduates at Trinity College Dublin.
