摘要:

受观察到的珠子包装在一个细字符串在这样的系统,如海葡萄和牙菌斑,我们研究了随机顺序吸附的圆柱体上的球体。我们确定的渐近分数覆盖的圆柱体作为唯一的参数的函数的问题,球半径的圆柱体半径(对于一个很长的圆柱体)使用的分析和数值模拟相结合的比率。检查的渐近结构,我们发现弱手征订购足够小的空间尺度。实验涉及胶体微球,可以通过静电力或DNA杂交不可逆地附着到硅线,使我们能够验证我们的预测的渐近覆盖。

英文摘要:

Inspired by observations of beads packed on a thin string in such systems as sea-grapes and dental plaque, we study the random sequential adsorption of spheres on a cylinder. We determine the asymptotic fractional coverage of the cylinder as a function of the sole parameter in the problem, the ratio of the sphere radius to the cylinder radius (for a very long cylinder) using a combination of analysis and numerical simulations. Examining the asymptotic structures, we find weak chiral ordering on sufficiently small spatial scales. Experiments involving colloidal microspheres that can attach irreversibly to a silica wire via electrostatic forces or DNA hybridization allow us to verify our predictions for the asymptotic coverage.
