Colorized EELS elemental map
This work was performed in collaboration with Dr. Phil Rice and Dr. Teya Topuria of IBM Almaden Research Center in San Jose, CA who provided expert assistance as well as the TEM specimen and access to their microscope facilities.

3D Reconstruction of Interplanetary Dust Particle

3D reconstruction of interplanetary dust particle. STEM tilt series acquired with a 806 HAADF detector from -61° to 68°. Aligned, reconstructed and visualized using 3D Reconstruction and 3D Visualization software. The iso-surfaces highlight two different intensity levels in the reconstruction.
Jointly acquired HAADF and MAADF signals
The HAADF signal (left) contrast is easily interpreted in terms of mass thickness of the material while the diffraction contrast MAADF signal (right) reveals highly detailed structural changes in the material. The optimized geometry makes this possible.

Image of phosphorus-containing macromolecular assemblies in the cell nuclei of drosophila larvae; dual-axis EFTEM tilt series acquired with a Tridiem energy filter from -66˚ to 66˚; for each axis phosphorus L-23 series (20 eV slit, pre-edge and post-edge) were collected; a jump-ratio series was calculated and the data were aligned and reconstructed using IMOD (University of Boulder, Colorado); finally, the reconstruction was rendered in the 3D visualization software; the inset highlights a sub-volume extracted using the 3D visualization ROI tool.
