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.
Colorized EELS elemental map of Ti L2,3-edges at 456 eV (green), Mn L2,3-edges at 640 eV (blue), La M4,5-edges at 832 eV (purple) and Sr L2,3-edges at 1940 eV (red).

Ultrafine TaOx nanoparticles were electrodeposited on carbon black (CB) powder in a nonaqueous Ta complex solution at room temperature, and the resultant TaOx/CB catalysts were assessed as oxygen reduction reaction (ORR) electrocatalysts for polymer electrolyte fuel cell (PEFC) cathodes.

Extending the capabilities of electron tomography with advanced imaging techniques and novel data processing methods, can augment the information content in three-dimensional (3D) reconstructions from projections taken in the transmission electron microscope (TEM).
The complementary nature of electron energy loss spectroscopy (EELS) and energy dispersive spectroscopy (EDS) signals makes it highly desirable to acquire both during transmission electron microscope (TEM) investigations of materials.
STEM EELS spectrum imaging can reveal composition and chemical changes at the nanoscale and even the atomic scale in many cases. To reveal this information, the researcher needs to optimize not only the spectrometer, but also the sample and the STEM configuration.
