Facilities

Several shared facilities are available to scientists involved in the MRSEC at UMass Amherst. The major instrumentation facilities are:

Besides these resources several other facilities are available to the MRSEC community, including Gel Permeation Chromatography, X-Ray Scattering or Thermal Characterization.

The Electron and Scanning Probe Microscopy Center is equipped with several Scanning and Transmission Electron Microscopes as well as Atomic Force Microscopes. Center pieces include a JEOL JEM-2200FS Energy Filtered Transmission Electron Microscope (EFTEM), which has the unique capability to image individual elements through an integrated Omega-type Electron Energy Loss Spectrometer (EELS). The microscope is equipped for Scanning Transmission Electron Microscopy (STEM), High Angle Annular Dark Field (HAADF) imaging and Energy Dispersive X-ray Spectroscopy (EDS) and is capable to perform tomography and cryo experiments.  The FEI Magellan 400 Field-Emission Scanning Electron Microscope (SEM), which, at even the lowest acceleration voltages and beam currents, reaches sub-nanometer resolution, is ideally suited for e-beam sensitive soft and bio materials. The instrument features besides  STEM and  HAADF, analytical capabilities such as  EDS and Electron Backscattering Diffraction (EBSD). Funding for both instruments was obtained through NSF Major Research Instrumentation (MRI) awards in 2009 and 2012. The center also houses a  Asylum/Oxford Research MFP-3D Scanning Probe Microscope, which is equipped with both hot and cold stages and a fluid cell and thus allowing heating and electrical measurement (Conductive AFM, Current Imaging, Electrostatic Force & Kelvin Force Microscopy). This instrument also allows for surface mechanical properties measurements.

The UMass Amherst High Field Nuclear Magnetic Resonance (NMR) Facility offers access to five spectrometers. The Agilent700 spectrometer has a coldprobe and is fully equipped for triple resonance and gradient experiments, while the DSX300 and Infinity300 are wide bore solid-state spectrometers, which are equipped for triple resonance experiments as well as high-speed magic angle spinning, static solids, and wideline experiments. The advanced spectrometers are capable of the latest techniques for structure determination of macromolecules, including multinuclear, multidimensional NMR analysis.

The Center is integrated firmly into the Materials Research Facilities Network (MRFN), a cooperative effort among MRSECs. The MRFN establishes protocols by which a MRSEC researcher can access facilities at other MRSECs. In addition, the MRFN encourages access to these facilities by investigators at major research institutions, small colleges lacking needed characterization tools, or investigators from any of a variety of institutions who wish to utilize materials characterization equipment and techniques. The MRFN strongly promotes facility use by undergraduate and minority-serving institutions, and provides a tremendous opportunity for leveraging NSF-funded MRSEC. Researchers interested in utilizing MRFN may contact Alexander Ribbe and/or Todd Emrick.
