This book gives an up-to-date, comprehensive assessment of current knowledge in the very fast-moving field of reverse micelles, ranging from physical studies to biotechnological applications. Starting with physical and spectroscopic studies of reverse micelle structure at the macro- and microstructural levels, topics dealt with in detail are the NMR spectroscopy of reverse micelles, fluorescence quenching kinetics, photochemical behaviour, role and behaviour of hydrated electrons in reverse micelles, including femtosecond phenomena, reactivity-dependent applications such as microlatex formation, protein partitioning, extraction, and purification. The microreactor characteristics of reverse micelles are shown to allow formation of semiconductor clusters, peptide synthesis through enzyme-catalyzed reactions, reaction product extraction, and enhanced-reactivity phenomena. The reactivity effects and their consequences are particularly highlighted throughout the book.
A multidisciplinary overview of bio-derived solvent applications, life cycle analysis, and strategies required for industrial commercialization This book provides the first and only comprehensive review of the state-of-the-science in bio-derived solvents. Drawing on their own pioneering work in the field, as well as an exhaustive survey of the world literature on the subject, the authors cover all the bases—from bio-derived solvent applications to life cycle analysis to strategies for industrial commercialization—for researchers and professional chemists working across a range of industries. In the increasingly critical area of sustainable chemistry, the search for new and better green solvents has become a top priority. Thanks to their renewability, biodegradability and low toxicity, as well as their potential to promote advantageous organic reactions, green solvents offer the promise of significantly reducing the pernicious effects of chemical processes on human health and the environment. Following an overview of the current solvents markets and the challenges and opportunities presented by bio-derived solvents, a series of dedicated chapters cover all significant classes of solvent arranged by origin and/or chemical structure. Throughout, real-world examples are used to help demonstrate the various advantages, drawbacks, and limitations of each class of solvent. Topics covered include: The commercial potential of various renewably sourced solvents, such as glycerol The various advantages and disadvantages of bio-derived versus petroleum-based solvents Renewably-sourced and waste-derived solvents in the design of eco-efficient processes Life cycle assessment and predictive methods for bio-based solvents Industrial and commercial viability of bio-based solvents now and in the years ahead Potential and limitations of methodologies involving bio-derived solvents New developments and emerging trends in the field and the shape of things to come Considering the vast potential for new and better products suggested by recent developments in this exciting field, Bio-Based Solvents will be a welcome resource among students and researchers in catalysis, organic synthesis, electrochemistry, and pharmaceuticals, as well as industrial chemists involved in manufacturing processes and formulation, and policy makers.
This work offers a comprehensive review of surfactant systems in organic, inorganic, colloidal, surface, and materials chemistry. It provides practical applications to reaction chemistry, organic and inorganic particle formation, synthesis and processing, molecular recognition and surfactant templating. It also allows closer collaboration between synthetic and physical practitioners in developing new materials and devices.
Wormlike micelles are elongated flexible self-assembled structures created from the aggregation of amphiphiles and their resulting dynamic networks have gained attention for a number of uses, particularly in the oil industry. Written by experts, Wormlike Micelles describes the latest developments in the field providing an authoritative guide on the subject. The book starts with an introductory chapter giving an overview of the area and then looks at the three key topics of new wormlike micelle systems, characterization and applications. New systems covered in the first part include reverse wormlike micelles and stimuli-responsive wormlike micelles. The second part explores cutting-edge techniques that have led to advances in the understanding of their structure and dynamics, including direct imaging techniques and the combination of rheology with small-angle neutron scattering techniques. Finally, the book reviews their use in oil and gas well treatments as well as surfactant drag reducing solutions. Aimed at postgraduate students and researchers, this text is essential reading for anyone interested in soft matter systems.
Provides a comprehensive treatment of surface chemistry and its applications to chemical engineering, biology, and medicine. Focuses on the chmical and physical structure of oil-water interfaces and membrane surfaces. Details interfacial potentials, ion solvation, and electrostatic instabilities in double layers.
The history of the liquid-liquid interface on the earth might be as old as that of the liquid. It is plausible that the generation of the primitive cell membrane is responsible for an accidental advent of the oldest liquid interfaces, since various compounds can be concentrated by an adsorption at the interface. The presence of liquid-liquid interface means that real liquids are far from ideal liquids that must be miscible with any kinds of liquids and have no interface. Thus it can be said that the non-ideality of liquids might generate the liquid-liquid interface indeed and that biological systems might be generated from the non-ideal interface. The liquid-liquid interface has been, therefore, studied as a model of biological membrane. From pairing two-phases of gas, liquid and solid, nine different pairs can be obtained, which include three homo-pairs of gas-gas, liquid-liquid and solid-solid pairs. The gas-gas interface, however, is practically no use under the ordinary conditions. Among the interfaces produced by the pairing, the liquid-liquid interface is most slippery and difficult to be studied experimentally in comparison with the gas-liquid and solid-liquid interfaces, as the liquid-liquid interface is flexible, thin and buried between bulk liquid phases. Therefore, in order to study the liquid-liquid interface, the invention of innovative measurement methods has a primary importance.

In this book we present ten chapters describing the synthesis and application of nanomaterials for health, food, agriculture and bioremediation. Nanomaterials, with unique properties are now being used to improve food and agricultural production. Research on nanomaterials is indeed revealing new applications that were once thought to be imaginary. Specifically, applications lead to higher crop productivity with nanofertilisers, better packaging, longer food shelf life and better sensing of aromas and contaminants. these applications are needed in particular in poor countries where food is scarce and the water quality bad. Nanotechnology also addresses the age old issue of water polluted by industrial, urban and agricultural pollutants. For instance, research produces nanomaterials that clean water more efficiently than classical methods, thus yielding water for drinking and irrigation. However, some nanomaterials have been found to be toxic. Therefore, nanomaterials should be engineered to be safe for the environment.
