TL;DR: The English-language dictionary defines wrinkles as small furrows, ridges, or creases on a normally smooth surface, caused by crumpling, folding, or shrinking as mentioned in this paper.

TL;DR: This paper discusses how and why wrinkles/buckles form in various materials, and describes several examples from everyday life that demonstrate that wrinkling or buckling is indeed a commonplace phenomenon that spans a multitude of length scales.

TL;DR: In this article, the case of colloids with one patch that serves as a model for molecular surfactants both with respect to their geometry and their interactions is discussed in detail, and these one-patch particles assemble into clusters that resemble surfactant micelles with the smooth and attractive sides of the colloids located at the interior.

TL;DR: In this paper, a simple model describing the order in the direction of the wrinkles is presented, and the measurements done by Bowden and coworkers (Appl. Phys. Lett. 75 (1999) 2558) on order near an edge are explained quantitatively by this model.

TL;DR: In this article, a mechanism for mesophase separation in a system of aggregating colloids is proposed, under conditions under which colloids can form equilibrium clusters with very large sizes, i.e., aggregation numbers of a thousand or more.
