This is the first monograph of its kind, where a comprehensive and systematic description of modeling and simulation of the smart polymer hydrogels in BioMEMS environment is provided. It will cover the development of the models in form of nonlinear coupled partial differential governing equations for the smart hydrogels. Further, benchmark results, for simulation and prediction of responsive behaviour of the smart hydrogels to solution pH, externally applied electric voltage, environmental temperature, glucose/carbohydrates and salt concentration/ionic strength that are basic stimuli in common BioMEMS devices, are also documented. Finally, it is written in as simple a manner as possible, such that it will make informative and easy reading for the expert, and concurrently it can serve as a rich reference source for a graduate student intending to work in this area.

The pH electrode offers by far the greatest sensitivity and rangeability of any industrial process measurement. To realize the full potential of this opportunity requires extrao rd inary performance of mixing equipment, contro l valves, reagent delivery systems, flow meters, control system design, and controller tuning. This book is designed to cover all of the bases but not get the user lost in the details. Since each of these topics could be a book in itself, the emphasis here is on cutting straight to the chase of concepts critical for a successful pH system. Key insights and rules of thumb a rc inserted to congeal principles and practices that address the essential requirements of pH applications. The book should appeal to both the generalist and the specialist. This book is designed to bring togethe r the chemist, control engineer, instrument technician, process engineer, and project manager to literally and figuratively put them on the same page.

With its immense capacity for adsorption from gas and liquid phases, activated carbon is a unique material. It occupies a special place in terms of producing a clean environment involving water purification as well as separations and purification in the chemical and associated industries. In these roles, it exhibits a remarkable efficiency as the international production is a littie more than half a million tonnes per year, with perhaps 2 million tonnes being in continuous use. This is equivalent to the allocation of 200 mg per person of the world population to be compared with the world use of fossil fuels of 2 tonnes per person of the world population. Much is already written about activated carbon such that the Google search engine will offer over one million pages from the Internet. These pages are mosdy descriptive and uncoordinated. Currendy, there exists a need for a text which establishes a framework into which factual information can be located and explained. Further, carbon science has expanded rapidly in recent years with considerable relevance to an understanding of activated carbon. Again, these information are mostly uncoordinated and need to be assimilated into a comprehensive story. This assimilation is the purpose of this book.

Superheavy elements – chemical elements which are much heavier than those which we know of from our daily life – are a persistent dream in human minds and the kernel of science fiction literature for about a century. This book is the first to treat the chemistry of superheavy elements, including important related nuclear aspects, as a self contained topic. It is written for those – students and novices -- who begin to work and those who are working in this fascinating and challenging field of the heaviest and superheavy elements, for their lecturers, their advisers and for the practicing scientists in the field – chemists and physicists - as the most complete source of reference about our today's knowledge of the chemistry of transactinides and superheavy elements. However, besides a number of very detailed discussions for the experts this book shall also provide interesting and easy to read material for teachers who are interested in this subject, for those chemists and physicists who are not experts in the field and for our interested fellow scientists in adjacent fields. Special emphasis is laid on an extensive coverage of the original literature in the reference part of each of the eight chapters to facilitate further and deeper studies of specific aspects. The index for each chapter should provide help to easily find a desired topic and to use this book as a convenient source to get fast access to a desired topic.

Conventional methods of synthesis of metal complexes as a rule involve use of metal salts or carbonyls. The final coordination or organometallic compounds are obtained as a result of a direct interaction of components (ligand and metal source), as well as by the exchange of ligands or metals, and using template synthesis. Meanwhile, the possibility of obtaining compounds directly from compact metals by the action of an electrical current was demonstrated at the end of the 19th century. Later it was reported that the synthesis of metal complexes from metals may be achieved in the gaseous phase (metals react in the form of atoms, ions or small particles), in solutions in the presence of oxidants or in donor-acceptor systems, and under surface friction conditions.

Supercritical fluid carbon dioxide (SF-C02) with its moderate critical constants, nonflammable nature and low cost provides an attractive alternative for replacing organic solvents traditionally used in chemical manufacturing processes. Minimizing liquid waste generation, easy separation of solutes and fast reaction rates are some of the advantages of the supercritical fluid extraction (SFE) technology over conventional solvent extraction methods. The solvation strength of supercritical C02 can be tuned by changing the density of the fluid phase, thus selective extraction and dissolution of compounds may be achieved in SFE processes. Because C02 is not regulated by the US EPA as a volatile organic compound, C02-based SFE processes are environmentally acceptable. The CO2 used in SFE is produced by other industrial processes (e.g. fermentation processes), therefore the gas vented into the atmosphere from the SFE processes does not contribute to the "green house" effect.

Impurities play an important role in different spheres of our day-to-day life. For example, trace amounts of impurities present in crystalline solids have a profound influence on their mechanical, electrical, thermal and optical properties. Consequently, the performance of different types of devices based on these solids depends on the nature and concentration of impurities present in them. Trace amounts of impurities present in a growth medium also have a strong influence on the processes of nucleation of crystallizing phases of the same substance and the subsequent growth of the nucleated phase. Typical examples of such processes are: beneficial mineralization such as the formation of bone and tooth, and pathological mineralization such as formation of human kidney stones, scale formation in domestic appliances and industrial plants, and crystallization of saturated fatty acid methyl ester components of biodiesel during cold seasons, clogging fuel lines and filters of engines.
