The Analytical and Surface Chemistry (ASC) program of the Division of Chemistry will support the collaborative research program of Prof. James Evans and Prof. Patricia Thiel of Iowa State University. Profs. Evans and Thiel and their students will study the self assembly and stability properties of metal nanostructures on surfaces. Detailed analysis and elucidation of these systems will be achieved by a closely integrated combination of experiment (scanning tunneling microscopy and surface sensitive diffraction) together with theory and simulation (from ab-initio DFT and semi-empirical calculations of energetics, to atomistic modeling of nanoscale organization utilizing Kinetic Monte Carlo simulation, and possibly hybrid/multiscale or coarse-grained continuum formulations). These studies will provide the basic scientific underpinnings for a broad range of nanotechnologies based on thin film deposition. The study will provide excellent educational training opportunities for graduate students and postdoctoral trainees in the cutting edge area of nanostructures imaging and theory.

化学部的分析和表面化学（ASC）计划将支持爱荷华州州立大学的James Evans教授和Patricia Thiel教授的合作研究计划。教授Evans和Thiel以及他们的学生将研究金属纳米结构在表面上的自组装和稳定性。这些系统的详细分析和阐明将通过实验（扫描隧道显微镜和表面敏感衍射）与理论和模拟（从从头算DFT和能量学的半经验计算，到利用动力学蒙特卡罗模拟的纳米级组织的原子模型，以及可能的混合/多尺度或粗粒度连续制剂）的紧密结合来实现。这些研究将为基于薄膜沉积的广泛的纳米技术提供基本的科学基础。该研究将为纳米结构成像和理论前沿领域的研究生和博士后学员提供极好的教育培训机会。
