Ion-Solvent Interaction of Water Soluble Drugs in Binary Solvent Systems


Book Description

At the outset, the author of the book welcomes his supervisor Prof. Dr. Smrutiprava Das who have joined me as coauthors of this text, a credit which would have been given earlier to them as they were helping in a latent way in the evolution of the book for the past six years. Six years have elapsed on the intellectual journey of writing a PhD thesis e-book in title “IonSolvent Interaction of Water Soluble Drugs in Binary Solvent Systems” in subject of chemistry. As chemical kinetics is growing at a dazzling pace, this edition has been demanding in a different way. In this 1 st edition, the book has been thoroughly described, enlarged and updated with chemical kinetics of ion-solvent interaction of water soluble drugs in binary solvent systems. Above and over all, this time the book has been presented in multicolour edition with profuse colour illustrations so as to increase its clarity, understand ability and legibility, especially of the diagrams. It is hoped that the present book, enlarged multicolour form, would serve in a still better way, the authors are keenly desirous of. Gratitude is expressed to the students and teachers, both from India and abroad, who have sent in their valuable suggestions which have been given due consideration. We are sincerely thankful to our publisher, Newredmars Education. We are also deeply indebted to my guide Prof. Dr. Smrutiprava Das for her sustained support of this endeavour from its inception; her wisdom has made all the difference. In fact, we are grateful to department of chemistry, Ravenshaw University, Odisha, India for their patience, buoyancy and encouragement of this venture which was more arduous than anticipated. Healthy criticism and suggestions for further improvement of the book are solicited.




Solvent Mixtures


Book Description

Compiling, comparing, and analyzing research from a wide range of abstracts, journal articles, and Web sites, this reference examines the properties, function, and behavior of binary, ternary, and multicomponent mixtures in the presence and absence of solutes. The author uniformly presents extensive data on the properties of solvent mixtures and describes their structures and interactions. He details the impact of preferential solvation on the environment, action, and components of chemical systems. The book highlights experimental approaches to determine when, and to what extent, preferential solvation has taken place and models for organic, ionic, macromolecular, and biochemical solutes.




Highlights in Solute-Solvent Interactions


Book Description

Most organic molecules retain their integrity when dissolved, and even though in such cases the effects exerted by solvents are, in the language of the coordination chemist, of the "outer sphere" kind, the choice of solvent can be critical to the successful outcome of an operation or preparation. Solubilities of reactants and products must be taken into account, and even if the organic principals in the reactions retain their integrity, many of the reagents are electrolytes, and their state of aggregation will affect their reactivity. In testifying to the importance of understanding solute-solvent interactions I draw attention to a large class of inorganic species for which the involvement in the chemical and physical properties by the solvent is even more deeply seated. It is comprised by the large body of metal atoms in low oxidation states for which solvent molecules intervene as reagents. At the same time, because the ions carry charges, the effects arising from outer sphere interactions are usually greater than they are for neutral molecules. To cite an example: when FeCb(s) is dissolved in water to form a dilute - say O. OlO- solution there is a complete reorganization of the coordination sphere of the cation. Whereas in the solid each cation is surrounded by six chloride ions, in the solution the dominant form is [Fe(H20)6]3+ followed by [Fe(H20)sCI]2+, [Fe(H20)4CI2]+, etc. in rapidly decreasing abundance.

The fourth edition is considerably expanded to include newselections on the AIDS epidemic, gay rights, the women's movement, and theClinton-Gore administration. In addition to articles by leading historians theeditors have chosen first-person accounts by participants in each of the issuesunder discussion, from Martin Luther King, Jr.'s "Letter from the BirminghamJail" to Al Gore's speech on environmentalism. With lively introductions to eachsection providing a context for the articles, this book helps students makesense of the tumultuous world of our time.




Electrochemical Engineering


Book Description

A Comprehensive Reference for Electrochemical Engineering Theory and Application From chemical and electronics manufacturing, to hybrid vehicles, energy storage, and beyond, electrochemical engineering touches many industries—any many lives—every day. As energy conservation becomes of central importance, so too does the science that helps us reduce consumption, reduce waste, and lessen our impact on the planet. Electrochemical Engineering provides a reference for scientists and engineers working with electrochemical processes, and a rigorous, thorough text for graduate students and upper-division undergraduates. Merging theoretical concepts with widespread application, this book is designed to provide critical knowledge in a real-world context. Beginning with the fundamental principles underpinning the field, the discussion moves into industrial and manufacturing processes that blend central ideas to provide an advanced understanding while explaining observable results. Fully-worked illustrations simplify complex processes, and end-of chapter questions help reinforce essential knowledge. With in-depth coverage of both the practical and theoretical, this book is both a thorough introduction to and a useful reference for the field. Rigorous in depth, yet grounded in relevance, Electrochemical Engineering: Introduces basic principles from the standpoint of practical application Explores the kinetics of electrochemical reactions with discussion on thermodynamics, reaction fundamentals, and transport Covers battery and fuel cell characteristics, mechanisms, and system design Delves into the design and mechanics of hybrid and electric vehicles, including regenerative braking, start-stop hybrids, and fuel cell systems Examines electrodeposition, redox-flow batteries, electrolysis, regenerative fuel cells, semiconductors, and other applications of electrochemical engineering principles Overlapping chemical engineering, chemistry, material science, mechanical engineering, and electrical engineering, electrochemical engineering covers a diverse array of phenomena explained by some of the important scientific discoveries of our time. Electrochemical Engineering provides the critical understanding required to work effectively with these processes as they become increasingly central to global sustainability.







Green Solvents II


Book Description

The conventional solvents used in chemical, pharmaceutical, biomedical and separation processes represent a great challenge to green chemistry because of their toxicity and flammability. Since the beginning of “the 12 Principles of Green Chemistry” in 1998, a general effort has been made to replace conventional solvents with environmentally benign substitutes. Water has been the most popular choice so far, followed by ionic liquids, surfactant, supercritical fluids, fluorous solvents, liquid polymers, bio-solvents and switchable solvent systems. Green Solvents Volume I and II provides a throughout overview of the different types of solvents and discusses their extensive applications in fields such as extraction, organic synthesis, biocatalytic processes, production of fine chemicals, removal of hydrogen sulphide, biochemical transformations, composite material, energy storage devices and polymers. These volumes are written by leading international experts and cover all possible aspects of green solvents’ properties and applications available in today’s literature. Green Solvents Volume I and II is an invaluable guide to scientists, R&D industrial specialists, researchers, upper-level undergraduates and graduate students, Ph.D. scholars, college and university professors working in the field of chemistry and biochemistry.
