Chemically synthetic nanomotors can consume fuel in the environment and utilize the self-generated concentration gradient to self-propel themselves in the system. We study the collective dynamics of an ensemble of sphere dimers built from linked catalytic and noncatalytic monomers. Because of the confinement from the fuel field and the interactions among motors, the ensemble of dimer motors can self-organize into various nanostructures, such as a radial pattern in the spherical fuel field and a staggered radial pattern in a cylindrical fuel field. The influence of the dimer volume fraction on the self-assembly is also investigated and the formed nanostructures are analyzed in detail. The results presented here may give insight into the application of the self-assembly of active materials.

受限条件下二聚体电机的自组装

化学合成的纳米马达可以消耗环境中的燃料，并利用自产生的浓度梯度在系统中自行推进。我们研究了由连接的催化和非催化单体构建的球体二聚体集合的集体动力学。由于燃料场的限制和马达之间的相互作用，二聚体马达的集合可以自组织成各种纳米结构，例如球形燃料场中的放射状图案和圆柱形燃料场中的交错放射状图案。还研究了二聚体体积分数对自组装的影响，并详细分析了形成的纳米结构。这里呈现的结果可能有助于深入了解活性材料自组装的应用。
