Using shape for self-assembly.
A 1980 poem by Alan Mackay outlines his aspiration 'to see what all have seen but think what none have thought': a daunting task, which he accomplished not once, but several times. A 'truly myriadminded, manysided man-a veritable triacontahedron' in the words of his colleagues and friends, Alan Mackay pursued a lifelong interest in the problems of morphogenesis and form, a comprehension of whic...
متن کاملShape selection in chiral self-assembly.
Many biological and synthetic materials self-assemble into helical or twisted aggregates. The shape is determined by a complex interplay between elastic forces and the orientation and chirality of the constituent molecules. We study this interplay through Monte Carlo simulations, with an accelerated algorithm motivated by the growth of an aggregate out of solution. The simulations show that the...
متن کاملSelf-assembly Planning of a Shape by Regular Modular Robots
We present a self-assembly planning algorithm to allow regular modular robots to assemble into some specified shapes. By tiling a shape using connected lattices in accordance with the robotic geometry, a parallel sequence is obtained to plan self-assembly in successive layers. Robots are identical and autonomous. They use local interactions to seek for a grown shape and update the connection in...
متن کاملControlled growth and shape-directed self-assembly of gold nanoarrows
Self-assembly of colloidal nanocrystals into complex superstructures offers notable opportunities to create functional devices and artificial materials with unusual properties. Anisotropic nanoparticles with nonspherical shapes, such as rods, plates, polyhedra, and multipods, enable the formation of a diverse range of ordered superlattices. However, the structural complexity and tunability of n...
متن کاملThe Influence of Shape on Parallel Self-Assembly
Self-assembly is a key phenomenon whereby vast numbers of individual components passively interact and form organized structures, as can be seen, for example, in the morphogenesis of a virus. Generally speaking, the process can be viewed as a spatial placement of attractive and repulsive components. In this paper, we report on an investigation of how morphology, i.e., the shape of components, a...
