Book Description
Active colloids are self-propelled particles, powered by energy harvested from the environment. This field of research has been growing over the past 20 years, attracting researchers from multiple disciplines. Biomedical engineers seek to harness the abilities of motile bacteria, materials chemists are fascinated by the concept of synthetic particles becoming autonomous and the new opportunities this presents, and soft matter physicists see active colloids as a model system for active matter, unravelling the principles of nonequilibrium systems. Beginning with the fundamentals, this book discusses the various types of active colloids, classified by energy source, as well as microbial active colloids. Several chapters are dedicated to theory and modelling, followed by an exploration of major developments and research frontiers. With expert contributions from around the world, this book is a useful reference and a source of inspiration for new and experienced researchers.

Book Description
Colloids are systems comprised of particles of mesoscopic size suspended in a liquid. They have recently been attracting increased attention from scientists and engineers due to the fact that they are nowadays present in many industrial products such as paints, oil additives, electronic ink displays and drugs. Colloids also serve as versatile model systems for phenomena and structures from solid-state physics, surface science and statistical mechanics, and can easily be studied using tabletop experiments to provide insight into processes not readily accessible in atomic systems. This book presents the lectures delivered at the 2012 Enrico Fermi School ‘Physics of Complex Colloids’, held in Varenna, Italy, in July 2012. The school addressed experimental, theoretical and numerical results and methods, and the lectures covered a broad spectrum of topics from the starting point of the synthesis of colloids and their use in commercial products. The lectures review the state-of-the-art of colloidal science in a pedagogical way, discussing both the basics and the latest results, and this book will serve as a reference for both students and experts in this rapidly growing field.

Book Description
This book presents a comprehensive review of various aspects of the novel and rapidly developing field of active matter, which encompasses a wide variety of self-organized self-driven energy-consuming media or agents. Most naturally occurring examples are of biological origin, spanning all scales from intracellular structures to swimming and crawling cells and microorganisms, to living tissues, bacterial colonies and flocks of birds. But the field also encompasses artificial systems, from colloids to soft robots. Intrinsically out of equilibrium and free of constraints of time-reversal symmetry, such systems display a range of surprising and unusual behaviors. In this book, the author emphasizes connections between fluid-mechanical, material, biological and technological aspects of active matter. He employs a minimum of mathematical tools, ensuring that the presentation is accessible to a wider scientific community. Richly illustrated, it gives the reader a clear picture of this fascinating field, its diverse phenomena and its open questions.

Book Description
This book brings together the many concepts and discoveries in liquid crystal colloids contributed over the last twenty years and scattered across numerous articles and book chapters. It provides both a historical overview of the development of the field and a clear perspective on the future applications in photonics. The book covers all phenomena observed in liquid crystal colloids with an emphasis on experimental tools and applications of topology in condensed matter, as well as practical micro-photonics applications. It includes a number of spectacular manifestations of new topological phenomena not found or difficult to observe in other systems. Starting from the early works on nematic colloids, it explains the basics of topological defects in ordered media, charge and winding, and the elastic forces between colloidal particles in nematics. Following a detailed description of experimental methods, such as optical tweezing and particle tracking, the book eases the reader into the theoretical part, which deals with elastic deformation of nematic liquid crystals due to inclusions and surface alignment. This is discussed in the context of basic mean field Landau-de Gennes Q-tensor theory, with a brief explanation of the free-energy minimization numerical methods. There then follows an excursion into the topology of complex nematic colloidal structures, colloidal entanglement, knotting and linking. Nematic droplets, shells, handlebodies and chiral topological structures are addressed in separate chapters. The book concludes with an extensive chapter on the photonic properties of nematic dispersions, presenting the concept of integrated soft matter photonics and discussing the concepts of nematic and chiral nematic microlasers, surface-sensitive photonic devices and smectic microfibers. The text is complemented by a large bibliography, explanatory sketches and beautiful micrographs.

Book Description
Colloidal Surfactants: Some Physicochemical Properties focuses on the study of surface active agents. This book elaborates the importance of surface active agents in detergency, textile industry, and biological research. The four distinctive features of the substance—moderate maximum concentration of molecularly dispersed species; surface and interfacial depression in very dilute solution; micelle formation above a certain concentration; and solubilization of water-insoluble substances by micelles, are also described. Other topics include the effect of molecular type on the critical micelle concentration, critical micelle concentration, interaction of paraffin chain electrolytes with colloids, and monolayer studies of surface active agents. This publication is suitable for chemists and specialists researching on colloidal surfactants.

Book Description
The important role of ?nely dispersed matter and surfaces in medicine is not always fully understood and appreciated. Speci?cally, ?ne particles (solid or liquid) in the size range of several nanometers to several micrometers have a tremendous effect on our lives, because they can be bene?cial or detrimental to our well-being. Such particles are present in living bodies as red blood cells or cholesterol crystals in the gall bladder. They are ubiquitous in the environment, where they can cause many diseases, such as asbestosis, silicosis, and black lung disease, but they are also used in diagnostic tests, drug delivery, and numerous other applications. More recently, evidence has become available that drug formulations with active components in a ?nely dispersed state may signi?cantly affect their functionality. Furthermore, with miniaturization of medical instrumentation, the size of the components is necess- ily reduced to colloid or even smaller range. This volume is a collection of several chapters dealing with diverse topics of colloids and surfaces relevant to medical applications. Thus, Siiman describes the use of optical properties of uniform colloidal particles as probes in ?ow cytometry. Giesche focuses on the preparations and properties of exceedingly uniform silica spheres for different uses, such as in chromatography. In modi?ed forms, silica p- ticles with incorporated dyes are employed in diagnostics and those combined with tiny magnetic entities in drug delivery.

Book Description
All engineering processes are processes of non-equilibrium because one or all of heat, mass, and momentum transfer occur in an open system. The pure equilibrium state can be established in an isolated system, in which neither mass nor heat is transferred between the system and the environment. Most engineering transport analyses are based on the semi-, quasi-, or local equilibrium assumptions, which assume that any infinitesimal volume can be treated as a box of equilibrium. This book includes various aspects of non-equilibrium or irreversible statistical mechanics and their relationships with engineering applications. I hope that this book contributes to expanding the predictability of holistic engineering consisting of thermo-, fluid, and particle dynamics.
