摘 要：Active matter,comprising many active agents interacting and moving in fluids or more complex environments,is a commonly occurring state of matter in biological and physical *** its very nature,active matter systems exist in nonequilibrium *** this paper,the active agents are small Janus colloidal particles that use chemical energy provided by chemical reactions occurring on their surfaces for propulsion through a diffusiophoretic *** a result of interactions among these colloids,either directly or through fluid velocity and concentration fields,they may act collectively to form structures such as dynamic clusters.A general nonequilibrium thermodynamics framework for the description of such systems is presented that accounts for both self-diffusiophoresis and diffusiophoresis due to external concentration gradients,and is consistent with *** predicts the existence of a reciprocal effect of diffusiophoresis back onto the reaction rate for the entire collection of colloids in the system,as well as the existence of a clustering instability that leads to nonequilibrium inhomogeneous system states.
