Kinetics of Water-Rock Interaction

Systems at the surface of the Earth are continually responding to energy inputs derived from solar radiation or from the radiogenic heat in the interior. These energy inputs drive plate movements and erosion, exposing metastable mineral phases at the Earth’s surface. In addition, these energy fluxes are harvested and transformed by living organisms. As long as these processes persist, chemical disequilibrium at the Earth’s surface will be perpetuated. Chemical disequilibrium is also driven by human activities related to production of food, extraction of water and energy resources, and burial of wastes. To understand how the surface of the Earth will change over time, we must understand the rates at which reactions occur and the chemical feedbacks that relate these reactions across extreme temporal and spatial scales. This book addresses fundamental and applied questions concerning the rates of water-rock interactions driven by tectonic, climatic, and anthropogenic forcings.

Kinetics of Catalytic Reactions--Solutions Manual

This textbook contains all the information needed for graduate students or industrial researchers to design kinetic experiments involving heterogeneous catalysts, to characterize these catalysts, to acquire valid rate data, to verify the absence of mass (and heat) transfer limitations, to propose reaction models, to derive rate expressions based on these models and, finally, to assess the consistency of these rate equations.The most recent technique to calculate heats of adsorption and activation barriers on metal surfaces, the BOC-MP approach, is discussed in detail. Methods to measure metal surface areas and crystallite sizes using x-ray diffraction, transmission electron microscopy and various chemisorption techniques are discussed. Different experimental techniques to determine the influence of mass transfer limitations, especially within the pores of a catalyst, are reviewed in detail, with a particular emphasis on liquid-phase reactions.

Climate change : Environment and history of the Near East

When the ?rst edition of this book was published in 2004, the following year 2005 has happened to have been the warmest year since 1880, when the ?rst reliable worldwide instrumental records came into existance. Claiming no li- age between the publication of our book and the temperature record, yet this record demonstrates the trend of increase in the global surface temperatures during thepast20years,reinforcedbyevidenceofriseofatmosphere’sand oceans’ temperatures, and increased melting of ice and snow in the arctic and antarctic regions as well as on mountain tops. All these observations are par- leled by the increase in the quantity of heat trapping gases in the atmosphere, causing most probably, the global greenhouse effect. In order to try and predict, what might be the impact of this effect on the on the natural and human environments of the Near East, (Figs. 1–1d) the authors adopted the saying that the past is the key for the future. The practical conclusion of this principle says that the acquiring knowledge of the impact of past climate changes on the nature and human societies, may allow conclusions with regard to future possible impact of climate changes. By correlating proxy data of all types, paleo-sea and lake levels, paleo-hydrology, pollen pro?les, environmental isotopes as well as archaeological and historical documents, the authors tried to collect as much as possible of this knowledge.

Chemokine biology : Basic research and clinical application ; Vol.1 : Immunobiology of chemokines

The discovery of interleukin-8 close to 20 years ago initiated a new field of research touching on many aspects of immunology and inflammation. Interleukin-8 is just one member of a large class of structurally related chemoattractant proteins, known as chemokines. Chemokines are involved in the traffic control of leukocytes, which bear the corresponding chemokine receptors on their surfaces. Today, it is clear that chemokines affect all aspects of immunology and even many unrelated fields, such as tissue development and tumor cell metastasis. Their fundamental contributions to chronic inflammatory diseases make them a principal target for the development of novel, anti-inflammatory therapeutics.

Characterization of Corrosion Products on Steel Surfaces

It is well known that corrosion products, i.e. rust, on iron and steel surfaces cannot be assigned a typical crystallographic structure with long-range order. In fact, the structure of rust is considered to be very complicated, and some forms of rust are assigned to the amorphous state for this reason. Accurate information about the atomic-scale structure of rust is important to shed light on corrosion mechanisms of metallic materials. And, since life of steel structures is often dominated by environmental degradation or corrosion of the surface, the structure of the rust formed on iron and steel surfaces during prolonged exposure to air is of great interest. This book describes the fundamental aspects of materials characterization for the ferric oxyhydroxides formed on steel surfaces.

Characteristics Finite Element Methods in Computational Fluid Dynamics

This book details a systematic characteristics-based finite element procedure to investigate incompressible, free-surface and compressible flows. The fluid dynamics equations are derived from basic thermo-mechanical principles and the multi-dimensional and infinite-directional upstream procedure is developed by combining a finite element discretization of a characteristics-bias system with an implicit Runge-Kutta time integration. For the computational solution of the Euler and Navier Stokes equations, the procedure relies on the mathematics and physics of multi-dimensional characteristics. As a result, the procedure crisply captures contact discontinuities, normal as well as oblique shocks, and generates essentially non-oscillatory solutions for incompressible, subsonic, transonic, supersonic, and hypersonic inviscid and viscous flows.

Cathodic Arcs : From Fractal Spots to Energetic Condensation

Cathodic Arcs: From Fractal Spots to Energetic Condensation is the first book in over a decade dedicated to the physics and technology of cathodic arcs. It includes a detailed account of arc history, a textbook-like introduction to cathode phenomena, and some basic physics of expanding plasmas; it deals with the infamous macroparticle issue and describes a host of practical plasma filter solutions. In contrast to previous books on cathodic arcs, the focus is on the relation of arc plasmas and their properties to surface modification and thin film deposition. The book contains sections on basic plasma physics and thin film materials science. It also deals with practical issues of coatings such as stress control and the often-underrated issue of the coating’s color. By stressing the fractal nature of cathode spots, the theme of fluctuations can be found throughout the book: fluctuations affect all plasma properties and thereby have consequences for plasma-based surface modifications and film growth.

Carbon in the Geobiosphere : Earth's outer shell

Carbon and carbon dioxide always played an important role in the geobiosphere that is part of the Earth’s outer shell and surface environment. The book’s eleven chapters cover the fundamentals of the biogeochemical behavior of carbon near the Earth’s surface, in the atmosphere, minerals, waters, air-sea exchange, and inorganic and biological processes fractionating the carbon isotopes, and its role in the evolution of inorganic and biogenic sediments, ocean water, the coupling to nutrient nitrogen and phosphorus cycles, and the future of the carbon cycle in the Anthropocene. This book is mainly a reference text for Earth and environmental scientists; it presents an overview of the origins and behavior of the carbon cycle and atmospheric carbon dioxide, and the human effects on them. The book can also be used for a one-semester course at an intermediate to advanced level addressing the behavior of the carbon and related cycles.

Capillary Forces in Microassembly : Modeling, Simulation, Experiments, and Case Study

Capillary Forces in Microassembly discusses the use of capillary forces as a gripping principle in microscale assembly. Clearly written and well-organized, this text brings together physical concepts at the microscale with practical applications in micromanipulation. Throughout this work, the reader will find a review of the existing gripping principles, elements to model capillary forces as well as descriptions of the simulation and experimental test bench developed to study the design parameters. Using well-known concepts from surface science (such as surface tension, capillary effects, wettability, and contact angles) as inputs to mechanical models, the amount of effort required to handle micro-components is predicted. These developments are then applied in a case study concerning the pick and place of balls in a watch ball bearing.
