Active colloids are microscopic particles, which self-propel through viscous fluids by
converting energy extracted from their environment into directed motion. We first explain …

Conspectus Diffusion is the principal transport mechanism that controls the motion of solute
molecules and other species in solution; however, the random walk process that underlies …

Conspectus Active matter, some of whose constituent elements are active agents that can
move autonomously, behaves very differently from matter without such agents. The active …

Self-propelled nanomotors use chemical energy to produce directed motion. Like many
molecular motors they suffer strong perturbations from the environment in which they move …

Manipulating transient mass transfer plays a crucial role in physics, chemistry, biology, and
other fields. One typical example is chemical waves, whose concentration profiles have …

Very small synthetic motors that use chemical reactions to drive their motion are being
studied widely because of their potential applications, which often involve active transport …

Living microorganisms are capable of a tactic response to external stimuli by swimming
toward or away from the stimulus source; they do so by adapting their tactic signal …

We study a mesoscopic model of a chemically active colloidal particle which on certain parts
of its surface promotes chemical reactions in the surrounding solution. For reasons of …

Multiparticle collision dynamics is a modern coarse-grained simulation technique to treat the
hydrodynamics of Newtonian fluids by solving the Navier-Stokes equations. Naturally, it also …

The fabrication of synthetic self-propelled particles and the experimental investigations of
their dynamics have stimulated interest in self-generated phoretic effects that propel nano …
