摘要： External micro-PIXE measurements were done to investigate the accumulation of Nd3+ on green algae species euglena gracilis. According to the Nd distribution patterns in the gracilis cells, the biosorption of Nd3+ to the cells compartments can be observed. Comparing elemental mappings of the cell treated with different doses of the 1 mg/mL Nd3+ solution, the Nd uptake of euglena gracilis cells do no relate with the doses. From distributions of Ca and Mg, it is found that the Ca is complementary to Nd partly, and the Nd and Mg distributions are alike to each other, showing that Nd may be mainly in the chlorophyll molecules. The biochemistry related is discussed.

摘要： The computed tomography was applied to setting STIM (Scanning Transmission Ion Microscopy) projections recorded at the Fudan Ion Beam Laboratory. In this work, in order to visualize the three-dimensional mass density distribution in several specimens, example for a test structure of hollow gold cyliner was presented together with a detailed description of the developed system, including data reconstruction code (Tomorebuild 2) and image display software (AMIRA�). Future development will allow the particle induced X-ray emission tomography for elemental analysis of micrometer-sized samples.
