Research for the development of more efficient photocatalysts has experienced an almost exponential growth since its popularization in early 1970 s. Despite the advantages of the widely used TiO2, the yield of the conversion of sun power into chemical energy that can be achieved with this material is limited" "prompting the research and development of a number of structural, morphological and chemical modifications of TiO2, as well as a number of novel photocatalysts with very different composition." Design of Advanced Photocatalytic Materials for Energy and Environmental Applications" provides a systematic account of the current understanding of the relationships between the physicochemical properties of the catalysts and photoactivity. The already long list of photocatalysts phases and their modifications is increasing day by day. By approaching this field from a material sciences angle, an integrated view allows readers to consider the diversity of photocatalysts globally and in connection with other technologies. "Design of Advanced Photocatalytic Materials for Energy and Environmental Applications" provides a valuable road-map, outlining the common principles lying behind the diversity of materials, but also delimiting the imprecise border between the contrasted results and the most speculative studies. This broad approach makes it ideal for specialist but also for engineers, researchers and students in related fields.

This book is written for scientists involved in the calibration of viscometers. A detailed description for stepping up procedures to establish the viscosity scale and obtaining sets of master viscometers is given in the book. Uncertainty considerations for standard oils of known viscosity are presented. The modern viscometers based on principles oftuning fork, ultrasonic, PZT, plate waves, Love waves, micro-cantilever and vibration of optical fiber are discussed to inspire the reader to further research and to generate improved versions. The primary standard for viscosity is pure water. Measurements of its viscosity with accuracy/uncertainty achieved are described. The principles of rotational and oscillation viscometers are explained to enhance the knowledge in calibration work. Devices used for specific materials and viscosity in non SI units are discussed with respect to the need to correlate viscosity values obtained by various devices. The description of commercial viscometers meets the needs of the user."
This book gives an overview of the most recent advances in emulsion science, from the preparation to the destruction of these materials. This book is intended for a large audience, from undergraduate students to senior scientists. A progressive and didactic approach is proposed for that purpose. The concepts presented should provide a useful guidance for formulating and controlling the lifetime of emulsion at laboratory and industrial scales. For easy comprehension, the text is illustrated by more than 70 figures. This book is a new edition of the one published in the series "Springer Tracts in Modern Physics (vol. 181)." The main difference is a more didactic approach which will allow the non-specialist reader to capture the essential concepts. We shall also incorporate the very last research results (solid-stabilized emulsions, metastability) and novel applications (Biotechnology).
Integral processes with dead time are frequently encountered in the process industry; typical examples include supply chains, level control and batch distillation columns. Special attention must be paid to their control because they lack asymptotic stability (they are not self-regulating) and because of their delays. As a result, many techniques have been devised to cope with these hurdles both in the context of single-degree-of-freedom (proportional-integral-differential (PID)) and two-degree-of-freedom control schemes. Control of Integral Processes with Dead Time provides a unified and coherent review of the various approaches devised for the control of integral processes, addressing the problem from different standpoints. In particular, the book treats the following topics: how to tune a PID controller and assess its performance; how to design a two-degree-of-freedom control scheme in order to deal with both the set-point following and load disturbance rejection tasks; how to modify the basic Smith predictor control scheme in order to cope with the presence of an integrator in the process; and how to address the presence of large process dead times. The methods are presented sequentially, highlighting the evolution of their rationale and implementation and thus clearly characterising them from both academic and industrial perspectives. Control of Integral Processes with Dead Time will serve academic researchers in systems with dead time both as a reference and stimulus for new ideas for further work and will help industry-based control and process engineers to solve their control problems using the most suitable technique and achieving the best cost: benefit ratio."
ILC has been a major control design methodology for twenty years; numerous algorithms have been developed to solve real-time control problems, from MEMS to batch reactors, characterised by repetitive control operations. Real-time Iterative Learning Control demonstrates how the latest advances in iterative learning control (ILC) can be applied to a number of plants widely encountered in practice. The authors provide a hitherto lacking systematic introduction to real-time ILC design and source of illustrative case studies for ILC problem solving; the fundamental concepts, schematics, configurations and generic guidelines for ILC design and implementation are enhanced by a well-selected group of representative, simple and easy-to-learn example applications. Key issues in ILC design and implementation in the linear and nonlinear plants that pervade mechatronics and batch processes are addressed. In particular, the book discusses: ILC design in the continuous- and discrete-time domains; design in the frequency and time domains; design with problem-specific performance objectives including robustness and optimality; design in a modular approach by integration with other control techniques; and design by means of classical tools based on Bode plots and state space. Real-time Iterative Learning Control will interest control engineers looking for examples of how this important control technique can be applied to a variety of real-life problems. With its systematic formulation and analysis of different system properties and performance and its exposition of open problems, academics and graduate students working in control will find it a useful reference to the current status of ILC.
This book looks at new ways of tackling the problem of separating reaction products from homogeneous catalytic solutions. The new processes involve low leaching supported catalysts, soluble supports such as polymers and dendrimers and unusual solvents such as water, fluorinated organics, ionic liquids and supercritical fluids. The advantages of the different possibilities are discussed alongside suggestions for further research that will be required for commercialisation. Unlike other books, in addition to the chemistry involved, the book looks at the process design that would be required to bring the new approaches to fruition. Comparisons are given with existing processes that have already been successfully applied and examples are given where these approaches are not suitable. The book includes: - New processes for the separation of products from solutions containing homogeneous catalysts - Catalysts on insoluble or soluble supports a" fixed bed catalysts - continuous flow or ultrafiltration - Biphasic systems: water - organic, fluorous - organic, ionic liquid a" organic, supercritical fluids (monophasic or biphasic with water, organic or ionic liquid) - Comparisons with current processes involving atmospheric or low temperature distillation - Consideration of Chemistry and Process Design - Advantages and disadvantages of each process exposed - Consideration of what else is need for commercialisation

A thermodynamically consistent description of the transport across interfaces in mixtures has for a long time been an open issue. This research clarifies that the interface between a liquid and a vapor in a mixture is in local equilibrium during evaporation and condensation. It implies that the thermodynamics developed for interfaces by Gibbs can be applied also away from equilibrium, which is typically the case in reality. A description of phase transitions is of great importance for the understanding of both natural and industrial processes. For example, it is relevant for the understanding of the increase of CO2 concentration in the atmosphere, or improvements of efficiency in distillation columns. This excellent work of luminescent scientific novelty has brought this area a significant step forward. The systematic documentation of the approach will facilitate further applications of the theoretical framework to important problems.

There is increasing political and environmental pressure on industry to clean up the water which it uses in many processes, and to re-use this water where possible. This cleaning is done using specially-developed industrial membranes and this book covers the types and design of membranes, how they work and in which industries they are used. Special attention is paid to the textile, food/ beverage, pharmaceutical, oil and pulp and paper industries where such membranes are in regular use.
This thesis addresses the development of a new force spectroscopy tool, correlation force spectroscopy (CFS) for the measurement of the properties of very small volumes of material (molecular to m3) at kHz-MHz frequency range. CFS measures the simultaneous thermal fluctuations of two closely-spaced atomic force microscopy (AFM) cantilevers. CFS then calculates the cross-correlation in the thermal fluctuations that gives the mechanical properties of the matter that spans the gap of the two cantilevers. The book also discusses development of CFS, its advantages over AFM, and its application in single molecule force spectroscopy and micro-rheology.
Mercury (Hg) is one of the most toxic heavy metals, harmful to both the environment and human health. Hg is released into the atmosphere from natural and anthropogenic sources and its emission control has caused much concern. This book introduces readers to Hg pollution from natural and anthropogenic sources and systematically describes coal-fired flue gas mercury emission control in industry, especially from coal-fired power stations. Mercury emission control theory and experimental research are demonstrated, including how elemental mercury is oxidized into oxidized mercury and the effect of flue gas contents on the mercury speciation transformation process. Mercury emission control methods, such as existing APCDs (air pollution control devices) at power stations, sorbent injection, additives in coal combustion and photo-catalytic methods are introduced in detail. Lab-scale, pilot-scale and full-scale experimental studies of sorbent injection conducted by the authors are presented systematically, helping researchers and engineers to understand how this approach reduces the mercury emissions in flue gas and to apply the methods in mercury emission control at coal-fired power stations. Readers will arrive at a comprehensive understanding of various mercury emission control methods that are suitable for industrial applications. The book is intended for scientists, researchers, engineers and graduate students in the fields of energy science and technology, environmental science and technology and chemical engineering.
Precursors of the modern chemical industry began to emerge in Northern Europe in the middle of the eighteenth century. The Industrial Revolution boosted activities such as soap-making, glassmaking and textiles production, which required increasing quantities of chemical products. The Lead Chamber process for the manufacture of sulphuric acid, required for the production of dye, was developed in the 1740s by John Roebuck then based in Birmingham. Production of this key commodity rose steadily. By the 1820s, British annual production had reached 10 000 tons of 100% acid. By 1900, Britain was producing one quarter of the world's output with an annual production approaching one million tons. Demand for alkalis for glassmaking and soap-making, for textile dyes and for bleach was also growing rapidly in the second half of the eighteenth century, and it became clear that existing sources of these materials would not be sufficient. In response to a prize established by the Academie des Sciences, Nicholas Leblanc had devised by 1791 a method for converting common salt into soda ash, which was to become the central operation of the world alkali industry for about one hundred years.

Man's use of enzymes dates back to the earliest times of civilization. Important human activities such as the production of certain types of foods and beverages, and the tanning of hides and skins to produce leather for garments, serendipitously took advantage of enzymes. Important advances in our understanding of the nature of enzymes and their action were made in the late 19th and early 20th centuries, seeding the explosive expansion from the 1950s and 60s onward to the present billion dollar enzyme industry. Recent developments in the fields of genetic engineering and protein chemistry are bringing ever more powerful means of analysis to bear on the study of enzyme structure and function that will undoubtedly lead to the rational modification of enzymes to match specific requirements and also the design of new enzymes with novel properties.

This book had its genesis in a symposium on gas hydrates presented at the 2003 Spring National Meeting of the American Institute of Chemical Engineers. The symposium consisted of twenty papers presented in four sessions over two days. Additional guest authors were invited to provide continuity and cover topics not addressed during the symposium. Gas hydrates are a unique class of chemical compounds where molecules of one compound (the guest material) are enclosed, without bonding chemically, within an open solid lattice composed of another compound (the host material). These types of configurations are known as clathrates. The guest molecules, u- ally gases, are of an appropriate size such that they fit within the cage formed by the host material. Commonexamples of gas hydrates are carbon dioxide/water and methane/water clathrates. At standard pressure and temperature, methane hydrate contains by volume 180 times as much methane as hydrate. The United States Geological Survey (USGS) has estimated that there is more organic carbon c- tained as methane hydrate than all other forms of fossil fuels combined. In fact, methane hydrates could provide a clean source of energy for several centuries. Clathrate compounds were first discovered in the early 1800s when Humphrey Davy and Michael Faraday were experimenting with chlorine-water mixtures.
