Bringing Scanning Probe Microscopy Up to Speed introduces the principles of scanning probe systems with particular emphasis on techniques for increasing speed. The authors include useful information on the characteristics and limitations of current state-of-the-art machines as well as the properties of the systems that will follow in the future. The basic approach is two-fold. First, fast scanning systems for single probes are treated and, second, systems with multiple probes operating in parallel are presented. The key components of the SPM are the mechanical microcantilever with integrated tip and the systems used to measure its deflection. In essence, the entire apparatus is devoted to moving the tip over a surface with a well-controlled force. The mechanical response of the actuator that governs the force is of the utmost importance since it determines the scanning speed. The mechanical response relates directly to the size of the actuator; smaller is faster. Traditional scanning probe microscopes rely on piezoelectric tubes of centimeter size to move the probe. In future scanning probe systems, the large actuators will be replaced with cantilevers where the actuators are integrated on the beam. These will be combined in arrays of multiple cantilevers with MEMS as the key technology for the fabrication process.

This volume, the proceedings of a 1998 international workshop, provides experimental evidence of the effects of correlation on the physical, chemical, and mechanical properties of materials, as well as the theoretical/computational methodology that has been developed for their study.

The third International Symposium on the Scientific Basis for Nuclear Waste Management was held in Boston, Massachusetts, on November 17-20, 1980, as part of the Annual Meeting of the Materials Research Society. The purpose of this Symposium was to provide an interdisciplinary forum for the discussion of scientific research dealing with all levels and types of radioactive wastes and their management. Since its inception in 1978, this annual Symposium has provided a unique opportunity for scientists of widely differing backgrounds to share in such discussions. The proceedings of the first two meetings were published as Volumes 1 and 2 in this series. The fourth Symposium is scheduled to be held in the autumn of 1981. The efforts of many people went into making this meeting a success. The scope of the 1980 Symposium was guided by the follow ing Steering Committee: K. J. Notz (Chairman), Oak Ridge National Laboratory, USA G. H. Daly, Department of Energy, USA D. E. Ferguson, Oak Ridge National Laboratory, USA R. H. Flowers, Atomic Energy Research Establishment, UK F.

This series of books, which is published at the rate of about one per year, addresses fundamental problems in materials science. The contents cover a broad range of topics from small clusters of atoms to engineering materials and involve chemistry, physics, and engineering, with length scales ranging from Angstroms up to millimeters. The emphasis is on basic science rather than on applications. Each book focuses on a single area of current interest and brings together leading experts to give an up-to-date discussion of their work and the work of others. Each article contains enough references that the interested reader can access the relevant literature. Thanks are given to the Center for Fundamental Materials Research at Michigan State University for supporting this series. M. F. Thorpe, Series Editor E-mail: thorpe@pa. msu. edu v PREFACE th th During the period 4 -8 August 1996, a conference with the same title as this book was held in Traverse City, Michigan. That conference was organized as a sequel to an interesting and successful WEM workshop in a similar area run by Profs. Hans Bonzel and Bill Mullins in May 1995. This book contains papers presented at the Traverse City conference. The book focuses on: atomic processes, step structure and dynamics; and their effect on surface and interface structures and on the relaxation kinetics of larger leng- scale nonequilibrium morphologies.

This book includes small and large scale applications of super conductivity. Part I, SQUIDs, comprises about 75% of this volume, and is devoted to small scale applications, mainly . uperconducting QUantum Interference Devices (SQUIDs), and the remainder, Part H, Machines, presents an updated review of large scale applications of superconduc tivity. The present book combined with the previous book Superconducting Machines and Devices: Large Systems Applications edited by S. Foner and B. B. Schwartz, Plenum Press, New York (1974) represents a detailed and most up-to-date review of the applications of superconducting tech nology. The text of the current book is suitable for advanced undergrad uates or graduate students in applied physics and engineering courses. The book should be valuable to scientists, engineers and technologists interested in the current status and future applications of superconduc tivity technology. The last 7 chapters in Part I review the major nation al efforts on small scale technology and should prove useful for industrial and government planners as weIl as scientists and engineers."

These volumes, 7 and 8, of Fracture Mechanics of Ceramics constitute the proceedings of an international symposium on the fracture mechanics of ceramic materials held at Virginia Polytechnic Institute and State University, Blacksburg, Virginia on June 19, 20 and 21, 1985. These proceedings constitute the fourth pair of volumes of a continuing series of conferences. The theme of this conference, as the previous three, focused on the mechanical behavior of ceramic materials in terms of the characteristics of cracks, particularly the roles which they assume in the fracture process. The 78 contributed papers by over 100 authors and co-authors represent the current state of the field. They address many of the theoretical and practical problems of interest to those concerned with brittle fracture. The program chairmen gratefully acknowledge the financial assistance for the Symposium provided by the EXXON Foundation, the Army Research Office, the National Science Foundation, and the Office of Naval Research. Without their support, this conference simply would not have been possible. The suggestions of Drs. J. C. Hurt, R. C. Pohanka, and L. Toth were particularly helpful in assuring the" success of this symposium. Special appreciation is extended to Professor J. I. Robertson, C. P. Miles Professor of History, whose presentation following the banquet on the American Civil War was very well received by the audience. Finally, we wish to also thank our joint secretaries, especially Karen Snider, for their patience and help in finally bringing these proceedings to press.

It is with great pleasure and satisfaction that I present to the international scientific community this collection of papers presented at the symposium on Surface Phenomena in Enhanced Oil Recovery held at Stockholm, Sweden, during August 20-25, 1979. It has been an exciting and exhausting experience to edit the papers included in this volume. The proceedings cover six major areas of research related to chemical flooding processes for enhanced oil recovery, namely, 1) Fundamental aspects of the oil displacement process, 2) Micro structure of surfactant systems, 3) Emulsion rheology and oil dis placement mechanisms, 4) Wettability and oil displacement mecha nisms, 5) Adsorption, clays and chemical loss mechanisms, and 6) Polymer rheology and surfactant-polymer interactions. This book also includes two invited review papers, namely, "Research on Enhanced Oil Recovery: Past, Present and Future," and "Formation and Properties of Micelles and Microemulsions" by Professor J. J. Taber and Professor H. F. Eicke respectively. This symposium volume reflects the current state-of-art and our understanding of various surface phenomena in enhanced oil recovery processes. The participation by researchers from various countries in this symposium reflects the global interest in this area of research and the international effort to develop che science and technology of enhanced oil recovery processes.

The synergism of the mechanics of nondestructive testing and the mechanics of materials response has great potential value in an era of rapid development of new materials and new applications for con ventional materials. The two areas are closely related and an advance in one area often leads to an advance in the other. As our understanding of basic principles increases, nondestructive testing is outgrowing the image of "black box techniques" and is rapidly becoming a legitimate technical area of science and engineering. At the present time, however, an understanding of the mechanics of nondestructive testing is lagging behind other advances in the field. The key to further development in the mechanics of nondestructive testing lies in the mechanics of the phenomena or response being investigated - a better understanding of materials response suggests better nondestructive test methods to investigate the response which, in turn, advances our understanding of materials response, and so on. With this approach in mind, the Materials Response Group of the Engineering Science and Mechanics Department at Virginia Polytechnic Institute and State University hosted a Conference on the Mechanics of Nondestructive Testing on September 10 through 12, 1980. Sponsors of the conference were the Army Research Office, the National Science Foundation, and the Engineering Science and Mechanics Department."

Organic Additives and Ceramic Processing: With Applications in Powder Metallurgy, Ink, and Paint describes the major manufacturing processes, such as slip casting, tape casting, injection molding, etc. The book covers each subject, including the ceramic processes, organic chemical structures, polymers, colloid science and others, starting from fundamental principles, with many literature references for further reading. After the fundamentals, detailed case studies from industrial applications are described for the optimization of solvents, dispersants, binders, plasticizers, lubricants and some minor additives. A wide range of information is covered, beginning with fundamental equations for students, and extending to advanced applications for development workers and factory problem solvers. Shanefield undertook this ambitious task only because of the previous lack of resources that address the growing need for detailed information on organic additives for ceramics. Suitable for use as a textbook and as a reference source for working ceramists and chemists who wish to supply the ceramics industry with additives.

Computer Aided Engineering may be defined as an approach to solving tech nological problems in which most or all of the steps involved are automated through the use of computers, data bases and mathematical models. The success of this ap proach, considering hot forming, is tied very directly to an understanding of material behaviour when subjected to deformation at high temperatures. There is general agreement among engineers that not enough is known about that topic -and this gave the initial impetus for the project described in the present study. The authors secured a research grant from NATO (Special Research Grant #390/83) with a mandate to study the "State-of-the-Art of Controlled Rolling." What follows is the result of that study. There are five chapters in this Monograph. The first one, entitled "State-of-the Art of Controlled Rolling" discusses industrial and laboratory practices and research designed to aid in the development of microalloyed steels of superior quality. Follow ing this is the chapter "Methods of Determining Stress-Strain Curves at Elevated Temperatures." The central concern here is the material's resistance to deformation or in other words, its flow strength, the knowledge of which is absolutely essential for the efficient and economical utilization of the computers controlling the rolling process."

This volume of Modern Aspects contains seven chapters. The major topics covered in the first six chapters of this volume include fundamentals of solid state electrochemistry; kinetics of electrochemical hydrogen entry into metals and alloys; oxidation of organics; fuel cells; electrode kinetics of trace-anion catalysis; nano structural analysis. The last chapter is a corrected version of chapter four from Volume 35. Faisal M. AI-faqeer and Howard W. Pickering begin the first chapter by going back to 1864 and Cailletet who found that some hydrogen evolved and was absorbed by iron when it was immersed in dilute sulfuric acid. The absorption of hydrogen into metals and alloys can lead to catastrophic failures of structures. They discuss the kinetics of electrochemical hydrogen entry into metals and alloys. In chapter three, Clyde L. Briant reviews the electrochemistry, corrosion and hydrogen embrittlement of unalloyed titanium. He begins by reviewing the basic electrochemistry and general corrosion of titanium. He also discusses pitting and galvanostatic corrosion followed by a review of hydrogen embrittlement emphasizing the formation of hydrides and the effect of these on titanium's mechanical properties. Christos Comninellis and Gy6rgy F6ti discuss the oxidative electrochemical processes of organics in chapter three. They begin by defining direct and indirect electrochemical oxidation of organics. They introduce a model that allows them to distinguish between active (strong) and non-active (weak) anodes. Different classes of organic compounds are used for kinetic models of organic oxidation at active and non-active type anodes.

Under the guidance of the German Federal Institute for Materials Research (BAM), the standards for fabrication and application of reference materials are presented here in comprehensive form. The areas covered are analytical chemistry, materials science, environmental analysis, clinical and forensic toxicological analysis, and gas and food analysis. A standard reference for every analytical laboratory.

Once again, it gives me a great pleasure to pen the Foreword to the Proceedings of the 15th International Conference on Thermal Conductivity. As in the past, these now biannual conferences pro vide a broadly based forum for those researchers actively working on this important property of matter to convene on a regular basis to exchange their experiences and report their findings. As it is apparent from the Table of Contents, the 15th Conference represents perhaps the broadest coverage of subject areas to date. This is indicative of the times as the boundaries between disciplines be come increasingly diffused. I am sure the time has come when Con ference Chairmen in coming years will be soliciting contributions not only in the physical sciences and engineering', but will actively seek contributions from the earth sciences and life sciences as well. Indeed, the thermal conductivity and related properties of geological and biological materials are becoming of increasing im portance to our way of life. As it can be seen from the summary table, unfortunately, proceedings have been published only for six of the fifteen con ferences. It is hoped that hereafter this Series will become increasingly well known and be recognized as a major vehicle for the reporting of research on thermal conductivity."

Both experimental and theoretical investigations make it clear that mesoscale materials, that is, materials at scales intermediate between atomic and bulk matter, do not always behave in ways predicted by conventional theories of shock compression. At these scales, shock waves interact with local material properties and microstructure to produce a hierarchy of dissipative structures such as inelastic deformation fields, randomly distributed lattice defects, and residual stresses. A macroscopically steady planar shock wave is neither plane nor steady at the mesoscale. The chapters in this book examine the assumptions underlying our understanding of shock phenomena and present new measurements, calculations, and theories that challenge these assumptions. They address such questions as: - What are the experimental data on mesoscale effects of shocks, and what are the implications? - Can one formulate new mesoscale theories of shock dynamics? - How would new mesoscale theories affect our understanding of shock-induced phase transitions or fracture? - What new computational models will be needed for investigating mesoscale shocks?

The clamor for non-carbon dioxide emitting energy production has directly impacted on the development of nuclear energy. As new nuclear plants are built, plans and designs are continually being developed to manage the range of challenging requirement and problems that nuclear plants face especially when managing the greatly increased operating temperatures, irradiation doses and extended design life spans. Materials for Nuclear Plants: From Safe Design to Residual Life Assessments provides a comprehensive treatment of the structural materials for nuclear power plants with emphasis on advanced design concepts. Materials for Nuclear Plants: From Safe Design to Residual Life Assessments approaches structural materials with a systemic approach. Important components and materials currently in use as well as those which can be considered in future designs are detailed, whilst the damage mechanisms responsible for plant ageing are discussed and explained. Methodologies for materials characterization, materials modeling and advanced materials testing will be described including design code considerations and non-destructive evaluation concepts. Including models for simple system dynamic problems and knowledge of current nuclear power plants in operation, Materials for Nuclear Plants: From Safe Design to Residual Life Assessments is ideal for students studying postgraduate courses in Nuclear Engineering. Designers on courses for code development, such as ASME or ISO and nuclear authorities will also find this a useful reference.

For emerging energy saving technologies superconducting materials with superior performance are needed. Such materials can be developed by manipulating the "elementary building blocks" through nanostructuring. For superconductivity the "elementary blocks" are Cooper pair and fluxon (vortex). This book presents new ways how to modify superconductivity and vortex matter through nanostructuring and the use of nanoscale magnetic templates. The basic nano-effects, vortex and vortex-antivortex patterns, vortex dynamics, Josephson phenomena, critical currents, and interplay between superconductivity and ferromagnetism at the nanoscale are discussed. Potential applications of nanostructured superconductors are also presented in the book.

My 12-year-old granddaughter Nina Alesi once asked me, "Grandpa, you are a scientist at IBM, so what do you do?" I tried to reply, "Oh, I watch atoms move. . . " But before I could finish this sentence, my 7-year-old grandson Vinnie interjected, "Grandpa, do atoms play soccer?" This book is about the games atoms play in diffusion and various other properties of materials. While diffusion has been studied for more than 100 years in solids, its importance, excitement, and intellectual chal lenges remain undiminished with time. It is central to understanding the relationship between the structure and properties of naturally occurring and synthetic materials, which is at the root of current technological development and innovations. The diversity of material has led to spec tacular progress in functional inorganics, polymers, granular materials, photonics, complex oxides, metallic glasses, quasi-crystals, and strongly correlated electronic materials. The integrity of complex materials pack ages is determined by diffusion, a highly interactive and synergic phe nomenon that interrelates to the microstructure, the microchemistry, and the superimposed physical fields. While the various physico-chemical properties of the materials are affected by diffusion, they determine diffu sion itself. This book, which is intended to document the diffusive processes operative in advanced technological materials, has been written by pio neers in industry and academia.

Today, multi-functional materials such as piezoelectric/ferroelectric ceramics, magneto-strictive and shape memory alloys are gaining increasing applications as sensors, actuators or smart composite materials systems for emerging high tech areas. The stable performance and reliability of these smart components under complex service loads is of paramount practical importance. However, most multi-functional materials suffer from various mechanical and/or electro-magnetical degra-dation mechanisms as fatigue, damage and fracture. Therefore, this exciting topic has become a challenge to intensive international research, provoking the interdisciplinary approach between solid mechanics, materials science and physics. This book summarizes the outcome of the above mentioned IUTAM-symposium, assembling contributions by leading scientists in this area. Particularly, the following topics have been addressed: (1) Development of computational methods for coupled electromechanical field analysis, especially extended, adaptive and multi-level finite elements. (2) Constitutive modeling of non-linear smart material behavior with coupled electric, magnetic, thermal and mechanical fields, primarily based on micro-mechanical models. (3) Investigations of fracture and fatigue in piezoelectric and ferroelectric ceramics by means of process zone modeling, phase field simulation and configurational mechanics. (4) Reliability and durability of sensors and actuators under in service loading by alternating mechanical, electrical and thermal fields. (5) Experimental methods to measure fracture strength and to investigate fatigue crack growth in ferroelectric materials under electromechanical loading. (6) New ferroelectric materials, compounds and composites with enhanced strain capabilities.

The increasing global demand for energy requires a versatile approach, prompting many researchers to focus on renewable bioenergy from different biomasses, especially cellulosic biomass. Such biomasses can be agricultural wastes, municipal wastes or direct harvests from high-yield energy corps. If properly pre-treated, the subsequent enzyme hydrolysis step is much more effective and can effectively minimises the waste disposal.

"Green Biomass Pretreatment for Biofuels Production " reviews a range of pretreatment methods such as ammonium fiber explosion, steam explosion, dilute acid hydrolysis, alkali hydrolysis, and supercritical carbon dioxide explosion focusing on their final sugar yields from hemicellulose, glucose yields from cellulose, as well as on their feasibilities in bioenergy production processes at various scales.

This book emphasises the tactical mobile and on-farm scales applications that use green pretreatments and processing technologies without the need of on-site waste treatment. Because of the varieties of different biomasses, no single pretreatment is expected to be the universal choice. Some of the pretreatment methods present niche applications are also discussed.

In the last few years the physics of turbulent plasma has undergone rapid development, beginning with the first works, in which the term "turbulence" was used in various ways, and ending with the fundamental studies which provide a thorough examina tion of the turbulent state of plasma. In physics it is usually found that value is not so much contained in specific results for a partic ular field as it is in the more general outlook and overall view of the problem. Occasionally the older results take on new mean ing after the general view of things is perfected. In the case of the physics of turbulent plasma, this general picture is now com plete, for the most part. The first review devoted to the problem of plasma turbulence was written by B. B. Kadomtsev in "Problems in Plasma Theory," edited by M. A. Leontovich, Volume 4, Moscow, Atomizdat (1964), p. 188; English Translation: "Plasma Turbulence," Academic Press, London (1965)]."

Over the years, numerous handbooks and design guides on the subject of plastics have been published. None of these dealt in any depth with the subject of this handbook-blow molding. The recent growth of blow molding as an economically feasible process has been rapid in many areas. This growth, coupled with the lack of technical publications relating to blow molding, prompted the Board of Directors of the Blow Molding Division of the Society of Plastic Engineers to undertake the assimilation of available information and the editing of this milestone publication. We believe that this Plastic Blow Molding Handbook will provide the reader with a greater understanding of the unique process characteristics of blow molding, enable the reader to apply proven techniques in developing new products and applications for blow molding, and will serve as a valuable reference for all who are interested in the plastics industry. Our thanks are heartily extended to the various authors for their con tributions to this pioneering effort in blow molding. J. H. Moran Chairman Blow Molding Division Society of Plastic Engineers xi Preface The blow molding of plastic articles has in the past had an aura of the mystic around it. As a result, little comprehensive work on the subject has been published. Advances in the technology of polymeric materials, machine controls, computer science, and management techniques have made it nec essary to correct the myths and magic."

Conventional synthetic materials, like metals, ceramics or glass, are usually isotropic substances, and their suitability for structural applications is achieved by morphological design and combination in the macroscopic scale. However, in modem engineering this is often not acceptable. As an alternative, the use of non-homogeneous, anisotropic materials, with significant stiffness and strength only in the directions these mechanical properties are really needed, can lead to enormous material (and weight) savings. This is the case of multiphase systems called composite materials. In these composites, different material parts are added and arranged geometrically, under clearly designed and controlled conditions. Usually, a structure of fibers provides strength and stiffness and a matrix helds them together, whilst providing the geometric form. Carbon fibers are among the high-performance fibers employed in these advanced structural composites, which are profoundly changing many of today's high technology industries. New research and development challenges in this area include upgrading the manufacturing process of fibers and composites, in order to improve characteristics and reduce costs, and modifying the interfacial properties between fibers and matrix, to guarantee better mechanical properties. The interdisciplinary nature of this "new frontier" is obvious, involving chemistry, materials science, chemical and mechanical engineering. Other topics, which more often are treated separately, are also important for the understanding of the processes of fiber production. Carbon filaments is one such topic, as the study of their mechanisms of nucleation and growth is clearly quite relevant to the production of vapour-grown carbon fibers.
