项目摘要
1029246JohannessonThis award provides funding for a high performance liquid chromatograph for biogeoechmical and trace element research and training. The HPLC will be coupled with an existing NSF-funded magnetic sector ICP-MS for high-resolution elemental measurements. The main research use will be for assessing trace element concentrations and speciation in natural waters in order to understand biogeochemical transformations. The oxidation-reduction state will be able to be inferred from the speciation distribution in environmental samples. A principal research theme will address inorganic-organic interactions through ligand complexes. The PIs arsenic geochemistry studies in groundwater will immediately benefit. Researchers in the School of Science and Engineering, the School of Medicine, and the School of Public Health and Tropical Medicine will be engaged in sharing the instrumentation. Xavier University of Louisiana, a historically African American university, has scientists who routinely use Tulane?s coordinated instrumentation facility (CIF). They will given access to the new instrumentation. The acquisition will play an important role in encouraging the participation of under-represented groups in the areas of science and engineering through such programs as the Louisiana Alliance for Minority Participation in Research Program, as well as through the PI?s outreach to women in sciences through the Newcomb College Institute. The will be incorporated into environmental geochemistry coursework ? including an outreach component investigating local water quality issues. The instrument will be incorporated into the CIF. A full-time staff scientist maintains the laboratory. The staff scientist will provide routine instrument service and maintenance. Per hour cost structure for CIF resources (HR-ICP-MS) will be used initially for cost-recovery. Instrument time will be scheduled according to CIF policy. The PI and staff scientist will train new users. ***
1029246约翰森该奖项为用于生物化学和微量元素研究和培训的高效液相色谱仪提供资金。HPLC将与现有的NSF资助的磁性部门ICP-MS相结合,用于高分辨率元素测量。主要的研究用途将是评估天然沃茨中的微量元素浓度和形态,以了解地球化学变化。氧化还原状态将能够从环境样品中的形态分布推断。一个主要的研究主题将通过配体络合物解决无机-有机相互作用。PI的地下水砷地球化学研究将立即受益。科学与工程学院、医学院以及公共卫生和热带医学学院的研究人员将参与共享仪器。路易斯安那州的泽维尔大学,一所历史上的非洲裔美国大学,有科学家经常使用杜兰?的协调仪表设施(CIF)。他们将被允许使用新仪器。此次收购将发挥重要作用,鼓励代表性不足的群体参与科学和工程领域,通过这些计划,如路易斯安那州联盟少数民族参与研究计划,以及通过PI?通过纽科姆学院研究所,将纳入环境地球化学课程?包括一个调查当地水质问题的外联部分。该仪器将被纳入CIF。一名全职科学家负责维护实验室。科学家将提供常规仪器服务和维护。最初将使用资本投资基金资源的每小时费用结构(人力资源-比较方案-管理系统)来回收费用。仪器时间将根据CIF政策安排。PI和科学家将培训新用户。***
