四聚体的随机顺序吸附

Random sequential adsorption of tetramers

Michał Cieśla

摘要:

采用随机顺序吸附(RSA)算法,对由四个相同球构成的四聚体的吸附进行了数值研究。四聚体被吸附在一个二维的,平坦的和均匀的表面上。研究了两种不同的吸附质模型:菱形和正方形;单体中心分别放在菱形和正方形的顶点上。数值模拟允许建立最大的随机覆盖率以及可用表面功能(ASF),这是决定吸附过程的动力学的关键。这些结果进行了比较与实验获得的数据KfrA质粒吸附。此外,测量了密度自相关函数。

英文摘要:

Adsorption of tetramer built of four identical spheres was studied numerically using the Random Sequential Adsorption (RSA) algorithm. Tetramers were adsorbed on a two dimensional, flat and homogeneous surface. Two different models of the adsorbate were investigated: a rhomboid and a square one; monomer centres were put on vertices of rhomboids and squares, respectively. Numerical simulations allow to establish the maximal random coverage ratio as well as the Available Surface Function (ASF), which is crucial for determining kinetics of the adsorption process. These results were compared with data obtained experimentally for KfrA plasmid adsorption. Additionally, the density autocorrelation function was measured.
