Collaborative Research: NIRT: The Role of Nano-Scale Colloids in Particle Aggregation and Trace Metal Scavenging in Aquatic Systems

0237624 Gaillard该建议针对纳米胶体在自然环境和工程系统中痕量金属和污染物的传输中所起的作用。包括微观方法(原子力显微镜和电子显微镜)、基于同步加速器的方法(SAXS、XAS)和多尺度建模的实验研究的结合将有助于阐明颗粒材料在水生系统中的重要性。该项目是一个协作和多学科的项目，结合了化学、生物学和建模的专业知识，研究纤维和大分子在无机胶体聚集中的作用。这项工作的结果应有助于了解淡水、河口和海洋水域通过运输和沉积进行自我净化的能力。特别令人感兴趣的是对淡水和海水之间的异同的理解。这项建议是对NSF 01-157 NIRT类纳米科学与工程倡议的响应。

0237624 Gaillard The proposal addresses the role that nano-scale colloids play in the transport of trace metals and pollutants in natural environmental and engineered systems.The combination of experimental studies encompassing microscopic methods (AFM and EM), synchrotron-based methods (SAXS, XAS), and multi-scale modeling will aid in elucidating the significance of particulate material in aquatic systems.This project is collaborative and multi-disciplinary, combining expertise from chemistry, biology, and modeling to investigate the role of fibrils and macromolecules in inorganic colloid aggregation. Results of this work should help in the understanding the self-cleansing capacity of fresh, estuarine and marine waters through transport and sedimentation. Of special interest is the understanding of the similarities and differences between freshwater and seawater.This proposal was received in response to the Nanoscale Science and Engineering Initiative, NSF 01-157, category NIRT.
