DOWNLOAD EBOOKThis open access book, published in the Soft and Biological Matter series, presents an introduction to selected research topics in the broad field of flowing matter, including the dynamics of fluids with a complex internal structure -from nematic fluids to soft glasses- as well as active matter and turbulent phenomena. Flowing matter is a subject at the crossroads between physics, mathematics, chemistry, engineering, biology and earth sciences, and relies on a multidisciplinary approach to describe the emergence of the macroscopic behaviours in a system from the coordinated dynamics of its microscopic constituents. Depending on the microscopic interactions, an assembly of molecules or of mesoscopic particles can flow like a simple Newtonian fluid, deform elastically like a solid or behave in a complex manner. When the internal constituents are active, as for biological entities, one generally observes complex large-scale collective motions. Phenomenology is further complicated by the invariable tendency of fluids to display chaos at the large scales or when stirred strongly enough. This volume presents several research topics that address these phenomena encompassing the traditional micro-, meso-, and macro-scales descriptions, and contributes to our understanding of the fundamentals of flowing matter. This book is the legacy of the COST Action MP1305 “Flowing Matter”.

DOWNLOAD EBOOKNamed after the two-faced roman god, Janus particles have gained much attention due to their potential in a variety of applications, including drug delivery. This is the first book devoted to Janus particles and covers their methods of synthesis, how these particles self-assemble, and their possible uses. By following the line of synthesis, self-assembly and applications, the book not only covers the fundamental and applied aspects, but it goes beyond a simple summary and offers a logistic way of selecting the proper synthetic route for Janus particles for certain applications. Written by pioneering experts in the field, the book introduces the Janus concept to those new to the topic and highlights the most recent research progress on the topic for those active in the field and catalyze new ideas.

DOWNLOAD EBOOKEmulsions are dispersions of droplets of one fluid within a second, immiscible fluid and have a wide range of applications from foodstuffs to pharmaceuticals to personal care products and agrochemicals. Emulsions are intrinsically unstable because of large interfacial area associated with the system. To obtain stable emulsions, the interfaces between immiscible fluids must be stabilized by emulsifying agents such as surfactants and colloidal particles. Surfactants refer to surface-active agents which prefer to segregate to interfaces between two immiscible fluids. Their surface activity originates from their amphiphilic structure. Colloidal particles can stabilize emulsions due to their tendency to attach strongly to the interface. It has been demonstrated that particles with amphiphilic structure (also known as Janus particles) can be synthesized. An important potential application of Janus particles comes from the fact that they could make unique solid surfactants, however, several questions needs to be answered: (1) It has been recognized for more than 100 years that surfactant molecules and homogeneous particles can attach to interfaces and stabilize emulsions. How would Janus particles be different from and, more importantly, advantageous over molecular surfactants and homogeneous particles in emulsion stabilization? (2) How does the structure or geometry of Janus particles influence their properties as solid surfactants? To answer these questions, thermodynamics of emulsion stabilization using amphiphilic Janus particles is investigated showing that they can indeed generate thermodynamically stable emulsion whereas emulsions stabilized by surfactant molecules and homogeneous particles are only kinetically stable. In addition, a new synthesis method is developed enabling the bulk synthesis of highly uniform pH-responsive Janus particles that are able to completely reverse their surfactant properties in response to changes in the solution pH. These Janus particles can stabilize different types of simple emulsions (oil-in-water and water-in-oil) at different pH and, more importantly, induce phase inversion of emulsions in response to changes in solution pH. Furthermore, one-step formation of stable multiple emulsions is demonstrated using these amphiphilic Janus. Multiple emulsions stabilized by these stimuli-responsive Janus particles can be induced to release the encapsulant by simply increasing the pH of the continuous phase. In conclusion, Janus particles represent promising systems as solid surfactants for making stable and smart emulsions.

DOWNLOAD EBOOKSuperhydrophobic surfaces, artificially mimicking lotus leaves, have captured the attention of scientists and engineers over the past few decades. Recent trends have shifted from superhydrophobicity to superominipohobicity, or superamphiphobicity. In addition, dynamic rather than static surface wetting/dewetting properties, which can be triggered by various stimuli, including temperature, pH, magnetic/electric fields, solvents, light exposure etc, have been highly sought after for commercial applications. This book will focus on recent topics related to various stimuli-responsive wetting/dewetting surfaces, and give an overview of the knowledge and concepts of how to design and establish these smart artificial surfaces, which can be used for technical developments in a wide variety research fields.
