The Environmental Chemical Sciences (ECS) program of the Division of Chemistry will support the research project of Prof. James Rice of South Dakota State University. Prof. Rice and his students will investigate the role of nanoparticles in the formation of self assembled Natural Organic Matter (NOM). They will apply scanning electron microscopy, atomic force microscopy, differential scanning calorimetry and isotopically-labeled lipids and amphiphiles as probes in combination with solid-state NMR spectroscopy, small-angle neutron scattering, and neutron spin-echo spectrometry to provide molecular level understanding of the self assembly process leading to achieve this goal. The project has the potential to increase our molecular level understanding of mechanisms that contribute to the persistence of organic carbon in soils and thus the global carbon cycle. As a practical outcome, the ability to control NOM self-assembly could lead to the development of sequestration mechanisms and strategies to increase its residence time in the soil. The project will provide excellent training opportunities to students and postdoctoral fellows in a highly interdisciplinary research area of great environmental importance.

化学系的环境化学科学（ECS）计划将支持南达科他州立大学的詹姆斯·赖斯教授的研究项目。 赖斯教授和他的学生将调查纳米颗粒在形成自组装自然有机物（NOM）中的作用。他们将应用扫描电子显微镜，原子力显微镜，差异扫描量热法和同位素标记的脂质和两亲物作为探针与固态NMR光谱，小角度中子中子散射以及中子旋转光谱仪的结合，以实现这一目标的工具，以实现这一目标，以实现这一目标。该项目有可能增加我们对有机碳在土壤中持续持续以及全球碳循环的机制的分子水平理解。作为一个实际结果，控制NOM组装的能力可能会导致隔离机制和策略的发展，以增加其在土壤中的停留时间。该项目将在高度跨学科的研究领域为学生和博士后研究员提供极大的培训机会。
