Click on the thumbnails above to select new image Data in the gallery include the following..... 1) Direct evidence of Pu adsorption onto amorphous Fe hydroxide  The NanoSIMS offers enough sensitivity to map trace elements (U, Pu) with sub-micron lateral resolution. Sorption of actinides, particularly plutonium, onto sub-µm-sized colloids increases their mobility, but these plutonium colloids are difficult to detect in the far-field. The authors identified actinides on colloids in the groundwater some km from their source. "Colloid Transport of Plutonium in the Far-Field of the Mayak Production Association, Russia." Alexander P. Novikov, Stepan N. Kalmykov, Satoshi Utsunomiya, Rodney C. Ewing, Francois Horreard, Alex Merkulov, Susan B. Clark, Vladimir V. Tchachev, Boris F. Myasoedov, SCIENCE, vol 314, 27 Oct 2006

This stitched example 800µm x 300µm. Stitching offers areas of up to 2 or 3mm. Typical Field Of View of individual frames is between  2 x 2 µm and 50 x 50 µm C.

3) Diffusion in metals & alloys Example of crack tip propagation in nuclear reactor steel: Cr oxide lines the crack surrounding Fe oxide within. Overlay: trace levels of boron ahead of the crack tip. The line scan extracted from the image clearly reveals boron segregation.  Courtesy of M.R. Kilburn, S. Lozano-Perez and C.A. English, C.R.M.
