Abstract:
Spherical neodymium–iron–boron magnets are permanent magnets that can be assembled into a variety of structures owing to their high magnetic strength. A one-dimensional chain of these magnets responds to mechanical loadings in a manner reminiscent of an elastic rod. We investigate the macroscopic mechanical properties of assemblies of ferromagnetic spheres by considering chains, rings and chiral cylinders of magnets. Based on energy estimates and simple experiments, we introduce an effective magnetic bending stiffness for a chain of magnets and show that, used in conjunction with classic resul

Abstract Grafting polymeric chains onto surfaces of nanoparticles generates amphiphilic Janus nanoparticles (JNPs) that can self-assemble into a variety of well-ordered and/or functional nanostructures. The self-assembly structures of JNPs can be designed by the manipulation of grafting schemes, but only if the self-assembly rule can be well understood. By using coarse-grained molecular dynamics (CGMD) simulations, we investigated the self-assembly process and morphology of triblock JNPs with varying chain lengths, chain ratios, and grafting topology.

We investigated the role of particle potential symmetry on self-assembly by Monte Carlo simulation with a particular view toward synthetically creating structures of prescribed form and function. First, we established a general tendency for the rotational potential symmetries of the particles to be locally preserved upon self-assembly. Specifically, we found that a dipolar particle potential, having a continuous rotational symmetry about the dipolar axis, gives rise to chain formation, while particles with multipolar potentials (e.g., square quadrupole) having discrete rotational symmetries le

The self-assembly behavior was investigated in equilibrium by constructing phase diagrams based on chain lengths.
