Corrosion is a degrading material process frequently encountered in engineering structures and components, which may lead to costly and catastrophic failures if not properly and timely addressed. This volume describes a wide spectrum of experimental and analytical studies, which provide a fairly comprehensive account of corrosion manifestations and methodologies for addressing them in structural and industrial design. As such, it is expected to make a valuable reference publication for engineers and scientists interested in the protection of structures and components from harmful and potentially ruinous corrosive action.The collected articles comprising this volume address issues which can be categorised into two main areas. The first is concerned with material science approaches to corrosion, that is, visual or instrumental means of assessing existing behaviour or effectiveness of corrective measures and techniques. The second part of the volume comprises boundary element simulations of cathodic protection schemes for the purpose of predicting and optimising their performance.A number of practical problems are analysed such as: the coating condition on a ballast tank wall; the impressed current cathodic protection of an offshore platform and minimizing a ship's electric and magnetic signature. Topics covered include: Elemental identification; Material loss; Strain fields; Stress corrosion cracking; Corrosion resistance; Fretting corrosion; Contact surface damage; Electrochemical testing; Coating conditions; Cathodic protection; Current density distribution; Pipelines and deep well casings; Electric and magnetic signatures; Coating damage effects; Galvanic corrosion.
This thesis uses a systems-level approach to study the cellular metabolism, unveiling new mechanisms and responses that were impossible to reach with traditional reductionists procedures. The results reported here have a potential application in areas like metabolic engineering and disease treatment. They could also be used in determining the accuracy of the gene essentiality of new genome-scale reconstructions. Different methods and techniques, within the contexts of Systems Biology and the field known as Complex Networks Analysis have been applied in this work to show different features of the robustness of metabolic networks. The specific issues addressed here range from pure topological aspec ts of the networks themselves to the balance of biochemical fluxes.
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
As the title suggests, we introduce a novel differential approach
to solution thermodynamics and use it for the study of aqueous
solutions. We evaluate the quantities of higher order derivative
than the normal thermodynamic functions. We allow these higher
derivative data speak for themselves without resorting to any model
system. We thus elucidate the molecular processes in solution,
(referred to in this book "mixing scheme"), to the depth equal to,
if not deeper, than that gained by spectroscopic and other methods.
We show that there are three composition regions in aqueous
solutions of non-electrolytes, each of which has a qualitatively
distinct mixing scheme. The boundary between the adjacent regions
is associated with an anomaly in the third derivatives of G. The
loci of the anomalies in the temperature-composition field form the
line sometimes referred as "Koga line." We then take advantage of
the anomaly of a third derivative quantity of 1-propanol in the
ternary aqueous solution, 1-propanol - sample species - H2O. We use
its induced change as a probe of the effect of a sample species on
H2O. In this way, we clarified what a hydrophobe, or a hydrophile,
and in turn, an amphiphile, does to H2O. We also apply the same
methodology to ions that have been ranked by the Hofmeister series.
We show that the kosmotropes (salting out, or stabilizing agents)
are either hydrophobes or hydration centres, and that chaotropes
(salting in, or destablizing agents) are hydrophiles.
There is currently significant interest in exploring and identifying new inorganic solar energy conversion systems based on Earth-abundant non-toxic materials for future sustainable energy applications and technologies. Developments in emergent inorganic absorbers are closely tied to the ability of researchers to correlate and predict device performance from structural and optical properties. The understanding of material structure and bonding and their effect on performance are key to developing guiding principles for design and screening of inorganic photovoltaic materials. Progress toward such understanding is facilitated by state-of-the-art tools for structural and electronic characterisation of semiconductor materials and interfaces, as well as device design and performance analysis. Further insight is provided by computer modelling and simulations. This volume brings together internationally leading scientists working in areas of material design and modelling, structural and electronic characterisation, and device design and performance analysis, to explore and exchange ideas on emerging inorganic thin-film photovoltaics based on Earth abundant non-toxic materials. In this volume, the topics covered include: Indium-free CIGS analogues Bulk and surface characterisation techniques of solar absorbers Novel chalcogenides, pnictides and defect-tolerant semiconductors Materials design and bonding

This book provides deep insight into the physical quantity known as chemical activity. The author probes deep into classical thermodynamics in Part I, and then into statistical thermodynamics in Part II, to provide the necessary background. The treatment has been streamlined by placing some background material in appendices. Chemical Activity is of interest not only to those in chemical thermodynamics, but also to chemical engineers working with mass transfer and its applications - for example, separation methods.
An Introduction to the Gas Phase is adapted from a set of lecture notes for a core first year lecture course in physical chemistry taught at the University of Oxford. The book is intended to give a relatively concise introduction to the gas phase at a level suitable for any undergraduate scientist. After defining the gas phase, properties of gases such as temperature, pressure, and volume are discussed. The relationships between these properties are explained at a molecular level, and simple models are introduced that allow the various gas laws to be derived from first principles. Finally, the collisional behavior of gases is used to explain a number of gas-phase phenomena, such as effusion, diffusion, and thermal conductivity.

This book describes advanced research on the structures and photochemical properties of polyatomic molecules and molecular clusters having various functionalities under cold gas-phase conditions. Target molecules are crown ethers, polypeptides, large size protonated clusters, metal clusters, and other complex polyatomic molecules of special interest. A variety of advanced frequency and time-domain laser spectroscopic methods are applied. The book begins with the principle of an experimental setup for cold gas-phase molecules and various laser spectroscopic methods, followed by chapters on investigation of specific molecular systems. Through a molecular-level approach and analysis by quantum chemical calculation, it is possible to learn how atomic and molecular-level interactions (van der Waals, hydrogen-bonding, and others) control the specific properties of molecules and clusters. Those properties include molecular recognition, induced fitting, chirality, proton and hydrogen transfer, isomerization, and catalytic reaction. The information will be applicable to the design of new types of functional molecules and nanoparticles in the broad area that includes applied chemistry, drug delivery systems, and catalysts.
This book summarizes the main advances in the mechanisms of combustion processes. It focuses on the analysis of kinetic mechanisms of gas combustion processes and experimental investigation into the interrelation of kinetics and gas dynamics in gas combustion. The book is complimentary to the one previously published, The Modes of Gaseous Combustion.
Imaging by Nuclear Magnetic Resonance (NMR) has been established in clinical diagnosis and is conquering materials science with a rapidly expanding number of applications in basic research as well as product and quality control for fluid flow, elastomers, and polymer materials. This book will provide graduate students, scientists and engineers with an introduction to the field. It is the first book on the subject and is likely to become the standard text for years to come.
This textbook provides an accessible introduction to physics for undergraduate students in the life sciences, including those majoring in all branches of biology, biochemistry, and psychology and students working on pre-professional programs such as pre-medical, pre-dental, and physical therapy. The text is geared for the algebra-based physics course, often named College Physics in the United States. The order of topics studied are such that most of the problems in the text can be solved with the methods of Statics or Dynamics. That is, they require a free body diagram, the application of Newton’s Laws, and any necessary kinematics. Constructing the text with a standardized problem-solving methodology, simplifies this aspect of the course and allows students to focus on the application of physics to the study of biological systems. Along the way, students apply these techniques to find the tension in a tendon, the sedimentation rate of red blood cells in haemoglobin, the torques and forces on a bacterium employing a flagellum to propel itself through a viscous fluid, and the terminal velocity of a protein moving in a Gel Electrophoresis device. This is part one of a two-volume set; volume 2 introduces students to the conserved-quantities and applies these problem-solving techniques to topics in Thermodynamics, Electrical Circuits, Optics, and Atomic and Nuclear Physics always with continued focus on biological applications.
This book details the rigorous requirements for refractories designed for aluminium metallurgical processes: reduction, cast house, and anode production. The author describes requirements specific to the properties and structure of refractory materials that differentiate it from materials used for ferrous metallurgy, among others. A comparison is drawn between the properties and structure of refractories and carbon cathode materials from different points of view: from the perspective of physical chemistry and chemical interactions during the metallurgical process and from the aspect of designing reduction pots and furnaces to accommodate the lifetime of metallurgical aggregates that are a part of aluminum refractory processes.
This book is intended to provide a course of infrared spectroscopy for quantitative analysis, covering both bulk matter and surface/interface analyses. Although the technology of Fourier transform infrared (FT-IR) spectroscopy was established many years ago, the full potential of infrared spectroscopy has not been properly recognized, and its intrinsic potential is still put aside. FT-IR has outstandingly useful characteristics, however, represented by the high sensitivity for monolayer analysis, highly reliable quantitativity, and reproducibility, which are quite suitable for surface and interface analysis. Because infrared spectroscopy provides rich chemical information-for example, hydrogen bonding, molecular conformation, orientation, aggregation, and crystallinity-FT-IR should be the first choice of chemical analysis in a laboratory. In this book, various analytical techniques and basic knowledge of infrared spectroscopy are described in a uniform manner. In particular, techniques for quantitative understanding are particularly focused for the reader's convenience.
Handbook of Flotation Reagents: Chemistry, Theory and Practice: Flotation of Gold, PGM and Oxide Minerals, Volume 2 focuses on the theory, practice, and chemistry of flotation of gold, platinum group minerals (PGMs), and the major oxide minerals, along with rare earths. It examines separation methods whose effectiveness is limited when using conventional treatment processes and considers commercial plant practices for most oxide minerals, such as pyrochlore-containing ores, copper cobalt ores, zinc ores, tin ores, and tantalum/niobium ores. It discusses the geology and mineralogy of gold, PGMs, and oxide minerals, as well as reagent and flotation practices in beneficiation. The book also looks at the factors affecting the floatability of gold minerals and describes PGM-dominated deposits such as Morensky-type deposits, hydrothermal deposits, and placer deposits. In addition, case studies of flotation and beneficiation in countries such as Canada, Africa, Russia, Chile, and Saudi Arabia are presented. This book will be useful to researchers, university students, and professors, as well as mineral processors faced with the problem of beneficiation of difficult-to-treat ores.
The aim of this book is to show how supramolecular complexity of
cell organization can dramatically alter the functions of
individual macromolecules within a cell. The emergence of new
functions which appear as a consequence of supramolecular
complexity, is explained in terms of physical chemistry.
The work describes the production technology of standard medical radionuclides using reactors and cyclotrons for patient diagnosis and therapy.
