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

[0237905] Lazarides该提案解决了纳米级胶体在自然环境和工程系统中运输微量金属和污染物中的作用。结合微观方法（AFM和EM），基于同步加速器的方法（SAXS， XAS）和多尺度建模的实验研究将有助于阐明颗粒物质在水生系统中的重要性。该项目是一个多学科合作项目，结合了化学、生物学和建模方面的专业知识，研究了原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、河口和海水通过运输和沉积的自净能力。特别有趣的是了解淡水和海水之间的异同。该提案是在纳米尺度科学与工程计划（ns01 -157）类别NIRT的响应中收到的。

0237905 Lazarides 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, SF 01-157, category NIRT.
