There is no doubt that the field of artificial membrane transport using synthetic ionophores has advanced remarkably in the past 15 years due primarily to the synthesis of new ionophores. Even though the theoretical framework substantially predated this activity, the merging of theory with transport experiment has often been sketchy. The purpose of this outline has been to examine key examples to illustrate the underlying principles and to suggest how experimental variables dominate the results obtained. To a very good approximation the assumption of a "diffusion" regime is often justified, is easily confirmed experimentally and provides a clear framework for exploitation of the inherent selectivity of a given ionophore. Thus for synthetic chemists who wish a "quick and nasty" experiment to examine the question of selectivity, the recipe is clear: a mixture containing all ions of interest in a standard experiment for each ligand of interest using a moderately stirred (100-200 rpm) cell and analysis of the mixture produced on the OUT side of the cell at a fixed, small extent of transport. Together with duplicates and controls, this modest set of experiments will place the results on an unambiguous footing from which clear conclusions about each ionophore's characteristics are readily obtained. For those with more detailed interests in the transport process the demands are correspondingly higher.

Here is the first book devoted completely to inorganic membrane separations and applications. It provides detailed information on all aspects of the development and utilization of both commercial and developmental inorganic membranes and membrane-based processes, pointing out their key advantages and limitations as separation tools. Characteristics, technological advances, and future applications of inorganic membranes are discussed in depth. An overview of the origins of these membranes provides a basis for understanding emerging technologies in the field. Coverage of thermal, chemical, surface, and mechanical properties of inorganic membranes includes discussion of pore diameter, thickness, and membrane morphology. You'll gain valuable insights into membrane modification, as well as the design and operation of membrane filtration units. Also included are sections on how to analyze mechanisms that affect flux feature models for prediction of micro- and ultrafiltration flux that help you minimize flux decline. Descriptions of cross-flow membrane filtration and common operating configurations clarify the influence of important operating parameters on system performance. Parameters influencing solute retention properties during ultrafiltration are identified and discussed or treated in detail.

The Handbook of Chemical and Biological Sensors focuses on the development of sensors to recognize substances rather than physical quantities. This fully inclusive book examines devices that use a biological sensing element to detect and measure chemical and biological species as well as those that use a synthetic element to achieve a similar result. A first port of call for anyone with a specific interest, question, or problem relating to this area, this comprehensive source of reference serves as a guide for practicing scientists and as a text for many graduate courses. It presents relevant physics to chemists, chemistry to materials scientists, materials science to electronic engineers, and fabrication technology to all of the above. In addition, the handbook is useful both to newcomers and to experienced researchers who wish to broaden their knowledge of the constituent disciplines of this wide-ranging field.

Ls book is an account of what physical chemistry h . . to say about the structural, electrical and transport properties of biological membranes and their simplest model-the lipid bilayer. The accent throughout is on basic ideas. In contrast to the essentially descriptive ap proach characteristic of texts on membrane biochemistry, our underlying themes are the role of force and entropy in maintaining membrane organization, in determining the electric fields and ionic environment of membranes, and in regulating the passage of molecules and ions across membranes. Although experimental findings will always be the touch stone against which theory will be tried, no attempt is made to present an exhaustive survey of experimental data. On the other hand, there is discussion of the nature and limitations of the results obtainable by the major laboratory techniques. The treatment is at the level of an advanced undergraduate course or an introductory survey suitable for post graduate students carrying out research in biochemistry, biophysics, or physiology. The mathematical demands on the reader are trivial. The few forbidding equations appearing in Chapter 7 are soon whittled away to simple practical expressions. Although the current-voltage characteristics of nerves are traditionally the province of biophysics rather than physical chemistry, certain aspects relevant to the electrical activity of nerves are nevertheless included in this text, namely, mem brane and diffusion potentials and conductivity fluctuations. Where rival theories exist, conflicting convictions have been presented, but not necessarily accorded equal approbation. The author has a viewpoint.

Although there is general agreement that exogenous electric and electromagnetic fields influence and modulate the properties of biological systems. there is no concensus regarding the mechanisms by which such fields operate. It is the purpose of this volume to bring together and examine critically the mechanistic models and concepts that have been proposed. We have chosen to arrange the papers in terms of the level of biological organization emphasized by the contributors. Some papers overlap categories. but the progression from ions and membrane surfaces. through macromolecules and the membrane matrix to integrated systems. establishes a mechanistic chain of causality that links the basic interactions in the relatively well understood simple systems to the complex living systems. where all effects occur simultaneously. The backgrounds of the invited contributors include biochemistry. biophysics. cell biology. electrical engineering. electrochemistry. electrophysiology. medicine and physical chemistry. As a result of this diversity. the mechanistic models reflect the differing approaches used by these disciplines to explain the same phenomena. Areas of agreement define the common ground. while the areas of divergence provide opportunities for refining our ideas through further experimentation. To facilitate the interaction between the different points of view, the authors have clearly indicated those published observations that they are trying to explain. i.e. the experiments that have been critical in their thinking. This should establish a concensus regarding important observations. In the discussion of theories.

Inorganic membrane science and technology is a new field of membrane separation technology which until recently was dominated by the earlier field of polymer membranes. Currently the subject is undergoing rapid development and innovation. The present book describes the fundamental principles of both synthesis of inorganic membranes and membrane supports and also the associated phenomena of transport and separation in a semi-quantitative form. Features of this book: - Examples are given which illustrate the state-of-the-art in the synthesis of membranes with controlled properties - Future possibilities and limitations are discussed - The reader is provided with references to more extended treatments in the literature - Potential areas for future innovation are indicated. By combining aspects of both the science and technology of inorganic membranes this book serves as a useful source of information for scientists and engineers working in this field. It also provides some observations of important investigators who have contributed to the development of this subject.
