HOMEWOOD CAMPUS IMAGING, MICROSCOPY, and MICROANALYSIS
The High-Resolution Analytical Electron Microbeam Facility (HRAEM)
Located in the Blaustein Department of Earth and Planetary Sciences, Room 143, Olin Hall, the High-Resolution Analytical Electron Microbeam Facility is a multi-user facility that resides in the Materials Charactrization and Processing (MCP) Core of the Whiting School of Engineering. It houses:
• an FEI Tecnai TF30 FEG equipped with a Gatan 200 EELS detector, Gatan Orius camera, and Oxford EDS detector; and
• a JOEL 8600 microprobe.
These instruments are the focus of high-resolution structural and analytical microscopy on the Homewood Campus; and they
are available to all users Hopkins-wide. Specifically, the Tecnai TF30 is a 300 keV atomic resolution TEM with a field
emission gun capable of point-to-point characterization of material at the nanoscale (<0.2 nm) and equipped with a high
current probe capable of extremely high resolution (~ 1 nm) chemical analyses.
Presently, ongoing research is leading to the development of new materials and advancing our fundamental understanding of
environmental chemistry, geochemistry, and physics at nanometer/even atomic dimensions; and research in these areas is
necessarily highly dependent on the ability to observe and characterize solids at these ultra-fine resolutions. Current research
projects that are currently being carried out in the HRAEM facility are processing and characterization of nanoscale materials,
dislocation core structures in intermetallic alloys, environmental chemistry (addressing sorption of toxic metals and other pollutants on soil minerals), development and characterization of rare-earth magnetostictive materials, nanoscale observations of porous semiconductors, the identification of failure mechanisms in materials with applications to manufacturing processes, and investigations in crystal chemistry and geochemistry.
