The Surface
and Microstructure Analysis Laboratory (SMAL) is
equipped with two conventional scanning electron
microscopes, one of which has an energy-dispersive
spectrometer (EDS) for qualitative and quantitative
chemical analysis. The Lab is also home to an environmental
SEM (ESEM), also equipped with an EDS spectrometer,
hot stages and a Peltier stage. With these stages,
imaging can be performed on small samples from
room temperature to 1500°C, allowing some melting
and sintering events to be observed. The ESEM also
allows some biological tissue and biomaterial specimens
can also be observed in the presence of moisture.
An electron probe microanalyzer (microprobe) with
wavelengeth-dispersive and energy-dispersive capabilities
is also housed at this facility. Additional capabilities
include transmission electron microscopy, atomic
force microscopy, and x-ray photoelectron spectroscopy.
