Abstract

Many materials (e.g. different types of inorganic and organic alloys) in the liquid state consist of fine particles or droplets dispersed in an external (fluid) matrix. Once the effects of gravity are no longer felt, the different densities of the involved phases no longer represent a constraint forcing the dispersed particles or droplets to separate from the fluid through sedimentation or flotation; exploring self-assembly principles becomes therefore possible. Self-induced particle ordering is indeed emerging as one of the most relevant or promising approaches to develop in-space heterogeneous systems or materials consisting of parts that can recognize and bind to each other or form specific templates or patterns.
