0237479 Burd 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.

0237479 Burd该提案涉及纳米级胶体在自然环境和工程系统中痕量金属和污染物的运输中所起的作用。（AFM和EM），基于同步加速器的方法（SAXS，XAS），和多尺度模拟将有助于阐明颗粒物质在水生系统中的重要性。该项目是合作和多学科的，结合化学，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、河口和海洋沃茨通过运输和沉积作用的自我净化能力。 特别令人感兴趣的是淡水和海水之间的相似性和差异的理解。这个建议是响应纳米科学和工程倡议，NSF 01-157，类别NIRT。
