We currently operate six laboratories within the MRL: TEMPO, Extensive analytical instrumentation for characterization of all kinds of materials. Training is available for all instruments. Equipment includes: a PPMS that measures DC Resistivity, AC Transport (AC Resistivity, Hall Coefficient, I-V Curve, & Critical Current), and Heat Capacity for small samples under controlled magnetic field to 7 Tesla and temperature from 1.9 to 400 K; a SQUID Magnetometer is for measuring the magnetic properties of small samples to 5 Tesla between 1.7 and 400 K, with a sensitivity of 10 -9 emu; a TGA/DTA is used for quantitative thermo analysis of a sample to 1100° C, it requires as little as 5 mg of sample; MS Accessory to the TGA for Evolved Gas Analysis; a DSC for quantitative heat capacity, Transition Enthalpy, Glass Transition, and Crystallinity from room temperature to 1400° C; an ICP for elemental analysis which measures down to 10 PPB; an X-Ray Diffractometer that can measure powders and thin films in the theta theta configuration from room temperature to 1500° C; a UV-Vis-NIR Spectrometer that measures the of transmission, absorbance, and diffuse reflectance spectrum of powder, solid, liquid, and thin film samples over a range of 220 to 2600 nm; a Fluorimeter that measures fluorescence, phosphorescence, and chemiluminescence of solid, powder, liquid, or thin film samples over a range of 200 to 800 nm; two BET Porosimeters that measure the surface area, pore size, and pore size distribution of powder samples; a Pycnometer for very precise density measurements of small solid samples. Computing, with Linux, Windows NT, and SGI workstations, a dedicated Beowulf computer cluster, and the campus SGI Origin 2000 supercomputer. Microscopy and Microanalysis with (i) three FEI transmission electron microscopes (two Tecnai 200kV microscopes and a Titan 300kV one for high resolution TEM/STEM, and EDS/EELS analysis); (ii) three FEI SEMs (XL30FEG, XL40FEG and Inspect S for high resolution SEM imaging, EDS spectrum imaging and cathodluminescence measurement); (iii) a FEI focus ion beam microscope (Duel-beam, Pt-deposition and EDS); (iv) six AFMs (a Asylum MFP-3D SL, a Asylum MFP-3D Bio system, two Veeco Dimensions, and two Veeco Multimode AFMs); (v) a PHI dynamic SIMS and a Kratos XPS System for surface analysis. Polymer Characterization, with equipment for the synthesis of polymers, and monomers (Schlenk lines) as well as polymer analysis equipment: Circular Dichroism (CD) used in the study of proteins, TA Differential Scanning Calorimeter (DSC) Q2000 temp. -90 °C to 400 °C, Dynamic Light Scattering (DLS) Brookhaven, Dynamic Mechanical Analyzer (DMA), Gel Permeation Chromatography (GPC) using chloroform with 0.25% TEA as a solvent (Analytical and Preparative), GPC using DMF with 0.1% of LiBr as a solvent, High Performance Liquid Chromatography (HPLC- Analytical and Preparative), Two Microwave Reactors (Biotage and CEM), Two Rheometers (with the oven and the water bath), Wyatt DynaPro NanoStar DLS, Wyatt Optilab rEX which can measure the absolute Refractive Index and the dn/dc which is specific refractive index increment, and Gas Chromatograph (GC). Spectroscopy, housing three Bruker Avance NMR Spectrometers: a 500MHz SB for both solutions and solids, a 300MHz WB for solids, a 200MHz SB for solutions, a Nicolet-Magna 850 IR Spectrometer with a Raman module, and a Varian Cary Eclipse Fluorimeter. X-ray facility, which houses three Rigaku rotating anode and three sealed tube x-ray sources supporting seven state-of-art x-ray spectrometers for (i) small and wide angle x-ray scattering and diffraction, (ii) thin-film characterization, (iii) in-situ powder diffractometry and (iv) small molecule x-ray crystallography. In addition, the facility has extensive optical imaging capabilities including a state-of-art laser scanning confocal microscope.
