Book Description
A number of apparently unrelated phenomena in biological systems (e.g., biopolymer aggregation, cell-cell interactions, ion transport across membranes) arise from the special properties of charged surfaces. A sym posium entitled "Electrical Double Layers in Biology", which took place at the Toronto meeting of the Electrochemical Society, 12-17 May 1985, focused on the common features of these phenomena. The papers presented at that symposium are collected here and they illustrate ways in which an under standing of electrical double layers can elucidate a problem in Biology. An example of this approach can be seen from the paper I presented on ion transport and excitation, where the "unusual" ion flows during nerve excitation are actually expected if one includes the effects of electrical double layers at membrane surfaces. Furthermore, the selectivity of the ion channels in these membranes can be better understood on this basis. Other presentations account for such observations as the changes in spacing between muscle proteins during contraction, the interactions of red cells to form rouleaux, the electrical properties of algal cell membranes, electrokinetic potentials during blood flow in arteries, etc. I trust that these papers will indicate the value of electrochemistry in the study of biological systems, an area of research usually called Bioelectrochemistry, and will encourage biologists to use these ideas when approaching related problems.

Book Description
The electrical double layer describes charge and potential distributions that form at the interface between electrolyte solutions and the surface of an object, and they play a fundamental role in chemical and electrochemical behaviour. Colloid science, electrochemistry, material science, and biology are a few examples where such interfaces play a crucial role. The focus of this book is on the application of modern liquid state theories to the properties of electric double layers, where it demonstrates the ability of statistical mechanical approaches, such as the classical density functional theory, to provide insights and details that will enable a better and more quantitative understanding of electric double layers. The book will be essential reading for advanced students and researchers in interfacial science and its numerous applications.

Book Description
Colloid and Interface Science in Pharmaceutical Research and Development describes the role of colloid and surface chemistry in the pharmaceutical sciences. It gives a detailed account of colloid theory, and explains physicochemical properties of the colloidal-pharmaceutical systems, and the methods for their measurement. The book starts with fundamentals in Part I, covering fundamental aspects of colloid and interface sciences as applied to pharmaceutical sciences and thus should be suitable for teaching. Parts II and III treat applications and measurements, and they explains the application of these properties and their influence and use for the development of new drugs. - Provides a clear description of the fundamentals of colloid and interface science relevant to drug research and development - Explains the physicochemical/colloidal basis of pharmaceutical science - Lists modern experimental characterization techniques, provides analytical equations and explanations on analyzing the experimental data - Describes the most advanced techniques, AFM (Atomic Force Microscopy), SFA (Surface Force Apparatus) in detail

Book Description
Since the first publication of the book, a surge of interest in physicochemical hydrodynamics (PCH) has produced a flurry of advances in the field, as researchers became aware of the subject’s practical applications across numerous disciplines. The Second Edition of Ronald F. Probstein’s Physicochemical Hydrodynamics is significantly expanded and revised to provide increased coverage of the field. All of the material was supplemented with problems for students, and a solutions manual is available for instructors. The continued demand for the book necessitates that the Second Edition be reprinted in paperback so that it may be more widely available to students and practitioners. This highly respected book emphasizes rational theory and its consequences to demonstrate the underlying unity of PCH, which allows diverse phenomena to be described in physically and mathematically similar ways. Physicochemical Hydrodynamics communicates the fundamentals while, at the same time, conveying the importance of applications of PCH to a variety of fields, including: mechanical, chemical, and environmental engineering; materials science, biotechnology, microfluidics, and fluid aspects of nanotechnology. Numerous illustrations, analogies, and examples highlight the text and help to clarify and solidify students’ and professionals’ understanding of the material.

Book Description
The general background of this monograph and the aim of it is described in detail in Chapter I. As stated in 1.7 it is written according to the principle that "when rigour appears to conflict with simplicity, simplicity is given preference", which means that it is intended for a rather broad public. Not only graduate students but also advanced undergraduates should be able to understand at least most of it. This monograph is the result of many years of inspiring discussions with a number of colleagues, for which I want to thank them very much. Especially I should mention the groups in Stockholm and La Jolla: in Stockholm, Dr Carl-Gunne Flilthammar and many of his collaborators, including Drs Lars Block, Per Carlqvist, Lennart lindberg, Michael Raadu, Staffan Torven, Miroslav Babic, and Itlgvar Axniis, and further, Drs Bo Lehnert and Bjorn Bonnevier, all at the Royal Institute of Technology. Of other col leagues in Sweden, I should mention Dr Bertel Laurent, Stockholm University, Dr Aina Elvius, The Stockholm Observatory, and Dr Bengt Hultqvist, Kiruna. In La Jolla my thanks go first of all to Dr Gustaf Arrhenius, who once invited me to La Jolla, which was the start of a most interesting collaboration; further, to Dr W.B.

Book Description
Symposium R, "Oxide Semiconductors" was held December 1-6 at the 2013 MRS Fall Meeting in Boston, Massachusetts. Oxide semiconductors are poised to take a more active role in modern electronics, particularly in the field of thin film transistors. While many advances have been made in terms of our understanding of fundamental optical and electronic characteristics, there remain many questions in terms of defects, doping, and optimal growth/synthesis conditions. This symposium proceedings volume represents recent advances in growth and characterization of a number of different oxide semiconductors, as well as device fabrication.

Book Description
This book covers the recently developed understanding of Electro-Mechano-Biology (EMB) in which the focus is primarily on the couplings between the electric and mechanical fields. The emphasis lies on the analytical and computational aspects of EMB at the cellular level. The book is divided into two parts. In the first part, the author starts by defining and discussing the relevant basic aspects of the electrical and mechanical properties of cell membranes. He provides an overview of some of the ways analytical modelling of cell membrane electrodeformation (ED) and electroporation (EP) appears in a variety of contexts as well as a contemporary account of recent developments in computational approaches that can feature in the theory initiative, particularly in its attempt to describe the cohort of activities currently underway. Intended to serve as an introductory text and aiming to facilitate the understanding of the field to non-experts, this part does not dwell on the set of topics, such as cellular mechanosensing and mechanotransduction, irreversible EP, and atomistic molecular dynamics modelling of membrane EP. The second (and larger) part of the book is devoted to a presentation of the necessary analytical and computational tools to illustrate the ideas behind EMB and illuminate physical insights. Brief notes on the history of EMB and its many applications describing the variety of ideas and approaches are also included. In this part, the background of the first principles and practical calculation methods are discussed to highlight aspects that cannot be found in a single volume.
