Established in fall 2000, the Penn State MRSEC Central Facilities Laboratory (CFL) is housed in Davey Laboratory, which is located on Penn State University Park Central Campus within a 10 minute walk of the academic departments of the Center participants. It currently focuses on advanced cryogenic characterization, including PPMS and SQUID capabilites. This includes a multimode atomic force microscopy (AFM)/magnetic force microscopy (MFM) / scanning tunneling microscopy (STM) system, two superconducting quantum interference device (SQUID) magnetometers for magnetization measurements over a temperature range of 2K-1000K, three physical property measurement systems (PPMS) for magneto-transport measurements over a temperature range from 50 mK - 400 K and magnetic fields from 0 - 9 T.

This high sensitivity XPS (Kratos Axis 165) is available for compositional and chemical state analysis of monolayers, thin films, and solid state materials. The system is presently configured with both dual anode(Mg, AlKa) and monochromatized (AlKa) Xray sources. The system has been configured for broad materials applications with the presence of a variable temperature sample stage, charge neutralization system (for insulating samples), ion gun (for depth profiling), and a rapid entry loadlock for high throughput analysis. This facility is operated cooperatively with the Department of Chemistry & Biochemistry.

The Michigan Ion Beam Laboratory (MIBL) for Surface Modification and Analysis was established in October of 1986. The Laboratory is part of the Department of Nuclear Engineering and Radiological Sciences in the College of Engineering, and is located on the University of Michigan’s North Campus. MIBL is part of the National Nanotechnology Infrastructure Network (NNIN). The laboratory was created for the purpose of advancing our understanding of ion-solid interactions by providing unique and extensive facilities to support both research and development in the field. Researchers have available to them several instruments for conducting ion beam surface modification and ion beam surface analysis under a wide range of conditions. Experiments can be conducted at high or low temperature, in ultra-high vacuums, in a reactive gas and in short turnaround times. A knowledgeable scientific staff and a large number of supporting facilities are also available for surface preparation and analysis. Cruise the site and see if anything interests you.

Chaikin, Pine, and Thompson combine their capabilities to create a benchtop “wind tunnel” mechanical testing facility where the mechanical properties of colloidal, composite, and mineralized model systems can be measured and their scaling relationships elucidated, with the aim of developing design principles for optimizing structures. This facility enables real-time visualization of deformations as stresses are applied, fractures propagate, and materials yield.

The Molecular Design Institute operates within the NYU Department of Chemistry at the nexus of key areas in physics and biology, serving as a springboard for interdisciplinary research with other NYU departments. The MDI complements the newly established Center for Soft Matter Research in the Department of Physics. These two initiatives offer a unique opportunity to examine self-assembly and hierarchical organization of complex materials across length scales ranging from the molecular to the colloidal, that is, from the nanoscale to the microscale. The existence of complementary center in the Physics and Chemistry will provide synergy, strengthening both departments in tandem. The MDI faculty, Professor Michael D. Ward, Professor Marcus Weck, Professor Bart Kahr, and Professor Adam Braunschweig, unite expertise in the design and synthesis of complex molecular and supramolecular architectures and materials. The MDI has procured facilities for cutting edge research. Since its ribbon cutting ceremony in May 2007, the MDI has hosted many guests from the United States and abroad.

Equipment located in the Rheological Facility measures the steady state and dynamic response of polymers undergoing shear. This includes a Rheometrics Mechanical Spectrometer, which provides complex modulus, relaxation time spectra, and transient stress response data. Viscosity measurements are provided by a Gottfert Rheograph 2001 capillary melt rheometer and a laboratory designed and built high pressure viscometer for supercritical fluids investigations. An AIC Linear Rheometer provides measurements of external flow properties and adhesive properties of polymers.

Rheo-optical responses are monitored by use of a laboratory constructed shear cell that mounts within a Zeiss optical microscope. This arrangement permits birefringence measurements of polymeric solutions and conoscopy measurements of flowing, liquid crystalline polymers. Small angle light scattering measurements on polymeric fluids under shear are obtained through the use of a specialized, custom built instrument. Rheology is the study of the flow and deformation of materials. The complex rheology of many polymers not only constrains potential applications, but it also limits the way that these materials can be processed. The Rheology Laboratory clusters instruments that measure the mechanical and optical properties of various sorts of polymeric fluids (solutions, gels, melts) as stresses and/or strains are applied. Instruments to characterize these properties for solid polymers are located within the MRSEC Characterization Facility.

Several devices located in the Rheology Laboratory measure the steady state and dynamic mechanical response of polymeric fluids undergoing shear. These include a Rheometrics Mechanical Spectrometer (complex modulus, relaxation time spectrum, transient stress response), a Goettfert Rheograph 2001 capillary melt rheometer (viscosity), and a home-built, high pressure viscometer for supercritical fluid investigations. An AIC Linear Rheometer provides the laboratory with a capability to measure extensional flow properties and also to perform adhesion testing. Additional specialized instruments probe the rheology of low viscosity fluids such as oligomers and dilute solutions.

To monitor rheo-optical reponse, investigators in the laboratory have constructed a special shear cell that fits within a Zeiss optical microscope, an arrangement permitting flow birefringence measurements for polymer solutions and conoscopy for flowing liquid crystalline polymers. A second home-built optical instrument makes possible small angle light scattering investigations for various types of polymeric fluids under shear.

This facility provides computational resources for mechanics research of Brown faculty and external collaborators. It operates as a cost center administered by CAMR with a full-time director (Scheuerman). The major equipment includes a 58 node Opteron dual processor-dual core (232 processors) High Performance Computing (HPC) cluster, 2 Polyserve scalable fileserver, 2 Red Hat cluster suite routers, MSA1000 SAN with ~1 TB of user storage and an MSL5026 tape library. To ensure optimal performance and utilization of all compute nodes, we have deployed Standard LSF (a job scheduler) and Fairshare (a job queuing algorithm) from the HP XC cluster software suite. We have divided the HPC cluster into two partitions for serial and parallel processing to best utilize the additional memory needed for serial jobs. We have implemented several layers of high availability solutions (hardware and software) to avoid any system downtime and loss of data. Subsequent yearly upgrades to the facility are estimated at $50,000. A new high-performance facility is being installed in conjunction with the recent University HPC facility built in collaboration with IBM. The CMRF portion will more than double the capability of the existing facility, enabling far larger and longer computations to be performed locally at Brown. Details of this facility will be provided once up and running.

The Semiconductor Epitaxy and Analysis Laboratory (SEAL) includes the first University Molecular Beam Epitaxy (MBE) facility developed in the state of Ohio (1994) and unique, world-class facilities to grow and characterize nanostructured electronic materials. SEAL’s inception as OSU’s MBE Laboratory came via interdisciplinary funding from OSU’s Center for Materials Research to Professor Ringel and rapidly became the central laboratory around which massive expansion of the electronic materials, optoelectronics and device research areas has occurred. Facilities for MBE growth of arsenide and phosphide based III-V compound semiconductors, epitaxial metallic multilayers, and SiGe, along with an array of sophisticated in-situ characterization tools, including x-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), and scanning tunneling microscopy, are linked along a common ultra-high-vacuum transfer assembly so that flexibly in-situ sample transfer between all deposition and characterization chambers is feasible. The ability to transfer between epitaxy chambers and atomic-scale and chemically-sensitive characterization tools within a UHV environment, coupled with the wide range of materials being studied [III-V compounds based on (Al,In,Ga)/(As,P), IV-IV semiconductors, magnetic and nonmagnetic metallic layers] make this a unique facility for leading edge research in electronic materials, heterostructures and nanostructures. SEAL incorporates major facilities obtained with equipment grants to EMDL and also to EMDL’s collaborators from the College of Engineering, Department of Physics and the Center for Materials Research who have contributed capabilities to the SEAL UHV cluster. Hence, the interdisciplinary nature of the Laboratory, which is at the core of its formation, translates into close collaborations between engineers, physicists, and industrial partners, providing unique research opportunities for students and senior researchers throughout the colleges of Engineering and Math & Physical Sciences.

SEAL also includes state-of-the-art materials and nanostructure characterization equipment vital to interrogate and understand properties of epitaxial materials. Of particular note is a Tandem High Resolution X-Ray Diffractometer – Scanning Photoluminescence system, which allows for simultaneous high-resolution triple axis x-ray diffraction and PL mapping over large wafer areas, an essential and unique tool for the lattice-mismatched heterostructures being developed by EMDL. Finally, SEAL is housed within Electrical Engineering’s 4000 sq. ft. Microfabrication Cleanroom facility, providing advantageous proximity to outstanding device fabrication facilities.
