abstractcts - 0113016 p。纳米粒子在二维和三维结构中的自组装继续受到相当多的关注，因为可以实现潜在的独特光学和电子特性。提出的工作是利用各种实验和计算模拟方法来研究二维金纳米颗粒的表面扩散速率和形成。薄层将首先用液滴形成，然后在项目中使用旋转涂布机进行本研究。提出了小角中子散射、原子力显微镜、动态光散射和准弹性光散射等技术。提出了基于分子动力学模拟的单粒子和双粒子相互作用的计算模拟，然后进行了大规模的布朗动力学模拟。

AbstractCTS-0113016P. Neogi, University of Missouri-RollaSelf-assembly of nanoparticles in 2-D and 3-D structures continues to receive considerable attention due to the potentially unique optical and electronic properties that can be achieved. The proposed work is on a variety of experimental and computational simulation methods to study the rate of surface diffusion and formation of the 2-D gold nanoparticles. The thin layer will first be formed with a droplet, and later in the project with a spin-coater for this study. A number of techniques, such as small angle neutron scattering, atomic force microscopy, dynamic light scattering, and quasi-elastic light scattering are proposed for this study. The computational simulations based on molecular dynamic simulations for single and two-particle interaction followed by large scale Brownian Dynamic simulations are proposed.
