Using high resolution TEM to aquire uranium speciation information of environmental relevance


EMSL Project ID
32706

Abstract

The proposed research will utilize high resolution transmission electron microscopy (TEM) to acquire uranium (U) speciation data. Previous work has demonstrated the ability of an environmental Pseudomonas sp. isolate to rapidly accumulate significant amounts of U under aerobic conditions, however we need more information regarding the molecular form of the accumulated U species. This data is needed to establish the relationship between U bio-accumulation and U mobility and fate. The work proposed therefore will be of general interest for environmental molecular sciences. To acquire the needed information, we propose to use high-resolution transmission electron microscopy (TEM) in a collaborative effort with Alice Dohnalkova. The results of the proposed work will provide valuable information regarding U-microbe interactions under aerobic conditions, an area of interest that is both environmentally relevant and under represented.
