Overview of Shared Facilities

Our MRSEC maintains a robust set of Shared Research Facilities for making, characterizing, measuring, and imaging many types of materials and samples. Our Shared Research Facilities play a major role providing crucial support to the evolving scientific and technical needs of the IRGs. Moreover, interactions that take place within these facilities often lead to the collaborative efforts between different research groups which are the hallmark of our program. From the training received, students acquire a broad interdisciplinary outlook on materials research, and this helps us transfer technical know-how from one generation of students to the next.

Most of facilities are headed by a professional PhD-level technical staff member and all are supervised by Materials Center faculty. Our technical staff maintains and improves the equipment, performs measurements or prepares samples, and especially, trains students, research associates, and faculty to use the equipment. All shared facilities are open-access and available to all internal, external academic, and industrial users. Some of these might be able to help you in solving a preparation or characterization problem in your company or lab. If so, please contact us. We would like these facilities to have maximum benefit and impact. Many of our members are also willing to share their expertise to help companies implement these techniques. If you're interested in exploring a specific technique with us. Please contact the technical director(s) of the facility of interest, or the faculty supervisor.

Some of the major services and equipment are highlighted below. Additionally, the Materials Center provides access to specialized, affiliated facilities such as the Institute for Biophysical Dynamics Nanobiology Facility, Biophysics Facility, Transmission Electron Microscopy and magnetic resonance imaging. In response to the needs of several of the IRGs, a number of facilities have been upgraded, reorganized, or newly established. Additional upgrades are planned as the scientific needs of our Center evolve.

Materials Preparation and Measurement Laboratory

Faculty Supervisor: H. Jaeger
Technical Staff: Dr. Q. Guo & Dr. J. Jureller

Website:  Materials Preparation and Measurement Laboratory

The Materials Preparation Laboratory provides facilities for sample fabrication, processing, patterning and characterization of many types of samples. Instrumentation encompasses scanning probe microscopes (AFM and STM), scanning electron microscopes (SEM), optical lithography and imaging, sample cutting-polishing, surface coating, thermal characterization, optical characterization via steady-state and time-resolved fluoresecence, absorbance, reflectance, Raman, and light scattering. The MPML is currently expanding its digital fabrication and rapid prototyping resources through the addition of 3D printers, a laser cutter, and a CNC micromill.

A key aspect of the Lab is extensive one-on-one training with experienced PhD-level staff. After extensive training that covers operational procedures and safety training, it is possible for all users, from undergrads, graduate students, and postdocs to external users of all levels, to operate instruments by themselves.  Qualified users are given 24/7 access to the instruments.  MPML staff may also provide direct service on an as-needed basis.

It provides a central hosting server, web server, email server, and print server.



Fast X-Ray Imaging Facility

Faculty Supervisor: H. Jaeger

In response to the need for x-ray imaging and tomography capabilities at our MRSEC we have developed a new mobile facility centered around a C-arm x-ray system. The heart of this facility is a state-of-the-art OrthoScan HD mini C-arm that uses a flat panel x-ray detector to allow for video rate imaging. The resolution is 2,000 x 1,500 pixels and the field of view can be as large as 6”x5”. The C-arm configuration means that source and detector are mounted at the ends of a c-shaped brace that can be rotated manually in two orthogonal directions as well as translated in xyz. This makes it possible to bring the unit to experiments in any of the labs of MRSEC faculty and to image components without removing them, as long as the C-arm will fit around the piece to be x-rayed (max. gap between source and detector 14”). The unit is fully computer controlled and allows for a variety of different imaging modalities. A special feature of this facility is an add-on we developed, which uses a computer controlled stepper system to rotate samples up to 6” tall and 3” wide at the center of the C-arm in order to perform tomographic imaging.


Image Processing Facility

Faculty Supervisor: S. Nagel

This mobile facility maintains a portable suite of high-speed digital video cameras with complementary capabilities. Some cameras are capable of imaging at 1,000,000 frames per second. The cameras may be signed out by MRSEC members for use in their indivdual laboratories. The purchase of these cameras were leveraged through MRSEC and other University support.

The Facility currently manages:

  • A Vision Research Phantom VEO640S camera (2560 x 1600 pixels, 6Gpx/s bandwidth, and 1,400 fps at full resolution)
  • A Vision Research Phantom v2512 camera (1280x800 pixels, 25Gpx/s bandwidth, and 25,600 fps at full resolution)
  • A Vision Research Phantom v1610 camera (1280x800 pixels, 16Gpx/s bandwidth, and 16,600 fps at full resolution)
  • Two Vision Research Phantom v12.1 cameras (1280x800 pixels, 6Gpx/bandwidth, and 6,242 ftps at full resolution)
  • A Vision Research Phantom v9.1 camera (1632x1200 pixels and 1,000 fps at full resolution)
  • A Vision Research Phantom v7.3 turbo camera (800x600 pixels and 6,688 fps at full resolution)
  • Two Vision Research Phantom v7.1 cameras (800x600 pixels): one color and one monochrome)

This facility has been extensively used in outreach activities as well as in research.  For example, the high speed video is used to film the events at the annual "Physics with a Bang!" lectures so that the audience can see the surprising phenomena involved in explosions, fracture and fluid behavior that occurs too rapidly to be observed by the human eye.


Rheometry Facility

Faculty Supervisor: H. Jaeger

We established this facility to characterize the stress/strain relationships and other rheological properties of complex fluids.  The facility maintains an Anton Paar MCR 301 rheometer with fully automated measurement capabilities in both stress and sheer rate control modes.  Tools for parallel plate, cone, as well as Couette measurement geometries are available.   The sample stage is temperature-stabilized and a solvent trap is available.  The system also has capabilities for applying electric fields (up to 5kV) and magnetic fields (up to 1 T) to characterize electro-and magneto-rheological fluids.
