标题： Attractive and repulsive terms in multi-object dispersion interactions

摘要： 诸如纳米线、纳米管和DNA之类的细丝状物体在物理、纳米科学、化学、生物和医学领域备受关注。 它们可以通过极长程的多物体范德华（vdW，色散）力相互作用，导致它们聚集成多物体束。 我们定量分析了它们的vdW相互作用，预测了交替变化符号的$N$-物体vdW能量贡献随着$N$的增加而变化。 我们还提供了新的见解，使这些趋势能够简单地用电子屏蔽和反屏蔽来理解。 相关的系统包括多价电解质双层、Nafion排斥区、细胞内皮表面层、微乳液界面和六方相、Gibbs的盐指现象、肌肉中的肌球蛋白纤维、神经元轴突内部的多个纳米管以及碳纤维材料。 显示英文摘要

摘要： Filamentary objects such as nano-wires, nanotubes and DNA are of current interest in physics, nanoscience, chemistry, biology and medicine. They can interact via exceptionally long-ranged many-object van der Waals (vdW, dispersion) forces, causing them to cluster into multi-object bundles. We analyse their vdW interactions quantitatively, predicting $N$-object vdW energy contributions that alternate in sign with increasing $N$. We also provide novel insights permitting these tendencies to be understood simply in terms of electronic screening and anti-screening. Relevant systems include polyelectrolyte double layers, Nafion exclusion zone, endothelial surface layer of cells, microemulsion interfaces and hexagonal phases, salt fingers in Gibbs Marangoni effects, myosin fibres in muscle, multiple nanotubes in the interior of neuronal axons, and carbon fibre materials.
