Nanotechnology is the science of manipulating
materials at the atomic and molecular level to develop new or enhanced
materials and products. MCLinc’s microscopy
laboratory has the tools required for Nanomaterials characterization for
research and development or prototype manufacturing. Our state-of-the-art
capabilities include and scanning electron microscopy (SEM) and
transmission electron microscopy (TEM) with energy dispersive x-ray
spectroscopy (EDS) and wavelength dispersive x-ray spectroscopy (WDS).
 MCLinc has five electron microscopes including a
JEOL
2000FX transmission electron microscope with 0.5 nanometer resolution and
a maximum magnification of 1,000,000x, a Hitachi S-5000 scanning
electron microscope with 0.6 nanometer resolution and a maximum
magnification of 1,000,000x, a Hitachi S-4500 scanning electron microscope
with 1.5 nanometer resolution and a maximum magnification of 500,000x, an
Electroscope
Corporation environmental scanning electron microscope (ESEM) with 4
nanometer resolution and a maximum magnification of 300,000x, and a JEOL
JXA 840 scanning electron microscope with 4 nanometer resolution and a
maximum magnification of 300,000x. MCLinc’s ESEM system is a unique
SEM instrument that allows the sample to be subjected to low-pressure gas
conditions (water vapor and other gases) at pressures up to 25 torr.
This allows the observation of reactions between nanomaterials and water
vapor or selected other gases.
 MCLinc has
the experience and instrumentation required to characterize bulk materials
used in nanomaterials manufacturing. MCLinc utilizes a collection of
techniques including x-ray photoelectron spectroscopy (XPS), x-ray
diffraction (XRD), x-ray fluorescence (XRF) and ICP-OES to provide
elemental, chemical state, morphological and speciation analyses.
MCLinc’s x-ray photoelectron spectrometer, for example, provides surface
analysis at 20 to 40 angstrom depth.
