A Scanning Electron Microscope, with a large chamber to allow for the visualization of structural materials, is available for students, faculty and staff of the university, as well as for external users who might have a need for microscopy.
Provided by an NSF MRI grant, the scanning electron microscope (SEM) is a characterization equipment used to analyze materials and devices down to the nanoscale (up to 1,000,000x at a resolution of 3 nm). SEMs can be used to analyze metals, ceramics, polymers and biomaterials. This state-of-the-art SEM can operate in high-vacuum or in environmental mode (necessary to characterize hydrated and biological specimens). Typical samples include bulk materials, both polished and fracture surfaces, whole components, thin films and powders.
SEM imaging and analysis capabilities in MicaPlex include secondary electron (SE), backscatter electron (BSE) and topographic BSE imaging; elemental analysis using energy dispersive spectroscopy (EDS); and crystallographic orientation/phase analysis using electron backscatter diffraction (EBSD). The SEM large chamber allows for the visualization of structural materials installed in small test frames for in-situ experiments. The laboratory is also equipped with optical microscope for preliminary visualization, micro-hardness/micro-indenter and argon environment-controlled sputter coater for non-metallic sample preparation
