Book Description
The past half century has seen an extraordinary growth in the fields of cellular and molecular biology. From simple morphologi cal concepts of cells as the essential units of living matter there has been an ever-sharper focus on functional organization of living systems, with emphasis on molecular dynamics. Thus, life forms have come to be defined increasingly in terms of metabolism, growth, reproduction and responses to environmental perturbations. Since these properties occur in varying degrees in systems below the level of cellular organization, there has been a blurring of older models that restricted the concepts of life to cellular systems. At the same time, a search has begun for elemental as pects of molecular and atomic behavior that might better define properties common to all life forms. This search has led to an examination of nonlinear behavior in biological macromolecules, whether in response to electrical or chemical stimulation, for example, or as a means of signaling along a molecular chain, or as a means of energy transfer. Experimental knowledge in this area has grown rapidly in the past decade, and in some respects has outstripped theoretical models adequate to ex plain these new observations. Nevertheless, it can be claimed that there is now an impressive body of experiments implicating non linear, nonequilibrium processes as fundamental steps in sequential operations of biological systems.

Book Description
This book collects the revised lectures held at Capri (Italy) in the period 2-6 May, 1988 in occasion of the International Course on "Worldwide Nonionizing Radiation Safety Standards: Their Rationales and Problems". The Course was organized by IRECE (Institute for Research in Electromagnetism and Electronic Components) of CNR (Italian National Council for Research) and was directed by professors Giorgio Franceschetti and Om P. Gandhi. The idea for this course arose from the continuing wide disparity in the electromagnetic (EM) radiation safety standards worldwide, and the confusion that this has caused in the public mind. The safety guidelines in the western countries have been nearly three orders of magnitude greater than the safety levels in the Eastern European countries. Even though the former have been slightly reduced and the latter have been increased somewhat in recent years, there is still a wide gap in the EM safety standards that are used. With the ever increasing use of EM energy the public is becoming increasingly aware of and concerned about the potential biohazards of EM fields. This problem is compounded by inadequate knowledge of nonthermal mechanisms of interaction of EM fields with biological systems. The lecturers for the Course were the recognized leaders in their respective areas within the discipline of Biological Effects of Electromagnetic Fields.

Book Description
Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. The role of electric and magnetic fields in biological systems forms the focus of this second volume in the Bioelectrochemistry series. The most prominent use of electric fields is found in some fish. These species generate fields of different strengths and patterns serving either as weapons, or for the purpose of location and communication. Electrical phenomena involved in signal transduction are discussed by means of two examples, namely excitation-contraction coupling in muscles and light transduction in photoreceptors. Also examined is the role of electrical potential differences in energy metabolism and its control. Temporal and spatial changes of the potential difference across the membranes of nerve cells are carefully evaluated, since they are the basis of the spreading and processing of information in the nervous system. The dielectric properties of cells and their responses to electric fields, such as electrophoresis and electrorotation, are dealt with in detail. Finally, the effects of magnetic fields on living systems and of low-frequency electromagnetic fields on cell metabolism are also considered. Further volumes will be added to the series, which is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.

Book Description
Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. Macromolecules, essentially nucleic acids, proteins and complex carbohydrates, are the building blocks of cell structure and function. This fifth volume in the "Bioelectrochemistry" series deals essentially with water-soluble biomacromolecules, since the properties of membrane-bound proteins are considered in other volumes of this series. The first chapter provides an extensive review of the structure, chemical reactivity and electromagnetic properties of nucleic acids. The following five chapters concentrate on proteins, their structure, folding and function, the electrochemistry of redox proteins and voltammetric methods. Special attention is devoted to the field of thiol/disulfide exchange as well as to one particular class of proteins, the iron-sulfur proteins. The last chapter considers the chemistry and properties of glycosaminoglycans, the complex charged polysaccharides of the cell surface and extracellular matrix. This series is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.

Book Description
In his 1959 address, "There is Plenty of Room at the Bottom," Richard P. Feynman speculated about manipulating materials atom by atom and challenged the technical community "to find ways of manipulating and controlling things on a small scale." This visionary challenge has now become a reality, with recent advances enabling atomistic-level tailoring and control of materials. Exemplifying Feynman’s vision, Handbook of Nanoscience, Engineering, and Technology, Third Edition continues to explore innovative nanoscience, engineering, and technology areas. Along with updating all chapters, this third edition extends the coverage of emerging nano areas even further. Two entirely new sections on energy and biology cover nanomaterials for energy storage devices, photovoltaics, DNA devices and assembly, digital microfluidic lab-on-a-chip, and much more. This edition also includes new chapters on nanomagnet logic, quantum transport at the nanoscale, terahertz emission from Bloch oscillator systems, molecular logic, electronic optics in graphene, and electromagnetic metamaterials. With contributions from top scientists and researchers from around the globe, this color handbook presents a unified, up-to-date account of the most promising technologies and developments in the nano field. It sets the stage for the next revolution of nanoscale manufacturing—where scalable technologies are used to manufacture large numbers of devices with complex functionalities.

Book Description
As stated by Buckminster Fuller in Operation Manual for Spaceship Earth, "Synergy is the behavior of whole systems unpredicted by separately observed behaviors of any of the system's separate parts". In a similar vein, one might define an intellectual synergy as "an improvement in our understanding of the behavior of a system unpredicted by separately acquired viewpoints of the activities of such a system". Such considerations underlie, and provide a motivation for, an interdisciplinary approach to the problem of unraveling the deeper mysteries of cellular metabolism and organization, and have led a number of pioneering spirits, many represen ted in the pages which follow, to consider biological systems from an elec trochemical standpoint. is itself, of course, an interdisciplinary branch of Now electrochemistry science, and there is no doubt that many were introduced to it via Bockris and Reddy's outstanding, wide-ranging and celebrated textbook Modern Electrochemistry. If I am to stick my neck out, and seek to define bioelec trochemistry, I would take it to refer to "the study of the mutual interac tions of electrical fields and biological materials, including living systems".

Book Description
The concept of self-organization is at the heart of the theory of complex systems. It describes how order can emerge from disorder in otherwise chaotic nonlinear dynamical systems. This book investigates and surveys the role of self-organization in a wide variety of disciplines. The contributions are written by world-renowned scientists and philosophers at a level that is accessible to nonspecialists.
