Book Description
This book aims to provide readers with some of the current trends in microemulsions as scalable chemical nanoreactors. The chapters include discussions on microemulsions as reaction media, taking advantage of both the special behavior of trapped water inside their microdroplets and their potential use as a template for nanomaterials. The information contained in this book covers topics that will be of interest to students and researchers in physical chemistry, chemical engineering, and material science. In addition, this book will serve as a tribute in memoriam to Prof. Julio Casado, Professor of Physical Chemistry at the Universities of Santiago de Compostela and Salamanca and Doctor Honoris Causa from the University of Vigo, who died on April 2, 2018. Sit tibi terra levis.

Book Description
Properties and Uses of Microemulsions is intended to provide the reader with some important applications and features of these systems. The intricate composition of microemulsions has made them applicable in many areas such as cosmetics, pharmaceuticals, food, agriculture, oil recovery, chemical synthesis of nanoparticles, and catalysts. An introductory chapter starts off with the description of these applications followed by methods of characterization. Thereafter, a few practical applications of microemulsions focusing on drug delivery, oil recovery, and formation of nanocatalysts are described followed by the third section discussing the theoretical and physical parameters predicting microemulsion properties. The use of spin-polarized paramagnetic probes, bending energetics, and study of self-propelled motion are some of the physical parameters employed to characterize the microemulsions.

Book Description
Nanoemulsions: Formulation, Applications, and Characterization provides detailed information on the production, application and characterization of food nanoemulsion as presented by experts who share a wealth of experience. Those involved in the nutraceutical, pharmaceutical and cosmetic industries will find this a useful reference as it addresses findings related to different preparation and formulation methods of nanoemulsions and their application in different fields and products. As the last decade has seen a major shift from conventional emulsification processes towards nanoemulsions that both increase the efficiency and stability of emulsions and improve targeted drug and nutraceutical delivery, this book is a timely resource. - Summarizes general aspects of food nanoemulsions and their formulation - Provides detailed information on the production, application, and characterization of food nanoemulsion - Reveals the potential of nanoemulsions, as well as their novel applications in functional foods, nutraceutical products, delivery systems, and cosmetic formulations - Explains preparation of nanoemulsions by both low- and high-energy methods

Book Description
This book describes the microemulsion phenomenon in a systematic manner and not only provides an up-to-date introduction to this topic but aslo serves as the basis for further development in the area.The progress of microemulsion research has taken place in well-defined stages. The introduction period was founded on Schulman‘s original discovery and was, as expected, focused on the interfacial free energy. Because Schulman obtained his microemulsions from a macroemulsion by the addition of a cosurfactant.The present stage is characterized by an extensively enhanced knowledge about structure and dynamics in these systems. This has led to the realization that the structure of the microemulsions is related both to solutions with critical behaviour and long range order structures, the lyotropic liquid crystals. These two aspects have been elucidated independently by the French groups and by the Lund Spectroscopy group.

Book Description
Microemulsions: Theory and Practice covers the development of the theory and practice of microemulsion systems. This book is divided into seven chapters that explore the physics and chemistry of microemulsions. This book deals first with the commercial history of microemulsions, from the discovery of carnauba wax emulsions to polymer emulsions. This topic is followed by discussions on the theoretical aspects of microemulsion formulation techniques and the design of other products. The subsequent chapter describes the microemulsion formulation with less solubilizer or emulsifier together with their optical properties. A chapter examines the mixed film theory that explains the dispersions, oil-water interface, and inferences in microemulsions. Another chapter considers the role of microemulsions in micellar solutions and their relations to the concentrations of different compounds. This chapter also looks into the association phenomena of three-component phase equilibria diagrams and liquids crystals to microemulsions. The concluding chapter discusses the role of the capillary and hydrostatic forces on the entrapment of oil in the reservoir and the necessary conditions for the displacement of entrapped oil. The important properties and economic aspects of a microemulsion slug required for the tertiary oil recovery are also covered in this chapter.

Book Description
In organic chemistry the simultaneous solubility of hydrophobic and hydrophilic reactants in a common solvent is an ubiquitous problem. Often either an expensive or a toxic solvent is needed. Alternatively, polar and non polar components are mixed into macroemulsions permitting them to react across the internal interface. However, macroemulsions display a comparatively small interfacial area. Thus, the reaction rate is low. Microemulsions feature an inherent vast interfacial area which facilitates significantly higher reaction rates. Furthermore, they allow a rather simple monitoring of the reaction kinetics by observing changes in the phase behavior. In this work the advantages of microemulsions as efficient reaction media for the photochemically induced Paternò Büchi reaction of pyruvic acid and 1 octene are elucidated. The amphiphilic reaction product 3 hexyl 2 methyloxetane 2 carboxylic acid influences the phase behavior of the microemulsion system significantly. With increasing UV exposure time the point of highest efficiency was shifted to lower temperatures and, interestingly, an increase of efficiency was detected. Hence, the newly created amphiphile acts as an efficient, hydrophobic cosurfactant. Additionally, with small angle neutron scattering and freeze fracture electron microscopy it was shown that the bicontinuous microstructure survives the UV irradiation. Another route towards green organic chemistry was opened by characterization of two new sustainable biosurfactants (mannosylerythritollipids (MEL) and cellobioselipids (CL)) in microemulsions.
