Design and operation of Janus particles have a great potential for applications in fields such as environmental remediation, electronic engineering, bio-imaging, bio-sensing, drug delivery and other biomedical tasks. Current research aims to imitate the molecular motors of biological systems by creating micro- and nano-scale particles which can exploit chemical energy so as to produce directional motion. The assembling of self-propelled particles and their movement can be controlled by using external fields, especially magnetic fields.

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.

This 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”.

The problem of locomotion at the microscale has to be faced by living microorganisms as well as in many artificial systems. Various intriguing strategies have been developed in order to achieve a directed swimming motion in spite of the lack of inertia. While biological microswimmers often rely on mechanical self-propulsion mechanisms, such as beating flagella or shape deformations, many realizations of artificial self-propelled colloidal particles are based on phoretic driving mechanisms. The main focus of this book is on the influence of the body shape on the dynamics. Different systems ranging from spherical particles, via deformable and rodlike microswimmers, to completely asymmetric objects are investigated. In particular, a theoretical framework for the dynamics of asymmetric self-propelled particles based on coupled Langevin equations for the translational and rotational motion is provided. In the last part of this book, the introduced theory is used in order to contribute to the understanding of the gravitactic behavior which is observed in many microorganisms. Although several explanatory approaches exist, the detailed origin of gravitaxis is still an unsolved question in microbiology. Here, by studying synthetic microswimmers, a possible explanation based on an asymmetric body shape is given. Regarding artificial self-propelled particles, an especially promising field is the development of novel micromachines. Such devices have great potential for medical purposes as well as for many other technological applications. By appropriately designing the particle shape based on the findings of this book the motional behavior can be systematically tuned.

Self-propelled objects (particles, droplets) are autonomous agents that can convert energy from the environment into motion. These motions include nonlinear behaviour such as oscillations, synchronization, bifurcation, and pattern formation. In recent years, there has been much interest in self-propelled objects for their potential role in mass transport or their use as carriers in confined spaces. An improved understanding of self-organized motion has even allowed researchers to design objects for specific motion. This book gives an overview of the principles of self-propelled motion in chemical objects (particles, droplets) far from their thermodynamic equilibrium, at various spatial scales. Theoretical aspects, the characteristics of the motion and the design procedures of such systems are discussed from the viewpoint of nonlinear dynamics and examples of applications for these nonlinear systems are provided. This book is suitable for researchers and graduate students interested in physical and theoretical chemistry as well as soft matter.

From molecular motors to bacteria, from crawling cells to large animals, active entities are found at all scales in the biological world. Active matter encompasses systems whose individual constituents irreversibly dissipate energy to exert self-propelling forces on their environment. Over the past twenty years, scientists have managed to engineer synthetic active particles in the lab, paving the way towards smart active materials. This book gathers a pedagogical set of lecture notes that cover topics in nonequilibrium statistical mechanics and active matter. These lecture notes stem from the first summer school on Active Matter delivered at the Les Houches school of Physics. The lectures covered four main research directions: collective behaviours in active-matter systems, passive and active colloidal systems, biophysics and active matter, and nonequilibrium statistical physics--from passive to active.

Theory of Electrophoresis and Diffusiophoresis of Highly Charged Colloidal Particles discusses the electrophoretic and diffusiophoretic motions of various colloidal entities, such as rigid particles, liquid droplets, gas bubbles, and porous particles, focusing on the motion-deterring double-layer polarization effect pertinent to highly charged particles, with the lowly charged ones serving as the limiting cases. Boundary effects such as those from a cylindrical pore, a solid plane, or an air-water interface are analyzed as well for the electrophoretic motion of the various particles considered. Dynamic electrophoresis is also explored and treated.The contents are suitable for researchers, graduate students, or senior college students with some basic background of colloid science and transport phenomena. As there is no closed-form analytical formula in general for the situation of highly charged particles, the results are presented with extensive figures and plots as well as tables under various electrokinetic situations of interest to facilitate the possible use of interested readers. - Provides a reliable quantitative prediction of highly charged particles motion with easy-to-apply charts and in-depth understanding of the underlying mechanisms - Offers an extensive treatment of direct quantitative predication for non-rigid systems, such as porous particles, liquid drops, and gels, which is especially valuable in proteins and DNA research - Discusses highly charged systems with a nearby boundary of practical interests, such as a pore, a solid plane, or an air-water interface, which is of vital interest in fields such as microfluidic operations and biomedical engineering - Affords special attention to the polarization effect
