Computer:  Personal computers are available to all group members for data acquisition and processing.  A molecular modeling laboratory is available that contains three Silicon Graphics Workstations and the Sybyl 6.7 modeling systems software with Molecular computer assisted design software and several force fields.


Laboratory:  The Sepaniak group occupies laboratories of >2,000 sq. ft. in Buehler Chemistry Hall which are well equipped for separations, laser spectroscopy, surface characterization, molecular modeling, and synthetic chemical experiments.  We also co-occupy an on-campus laboratory of 600 sq. ft. in the Science and Engineering Research Facility (SERF) which is dedicated to sensor-MEMS development.


Major Equipment:  Available in the Sepaniak laboratories are the following equipment: Lasers: Lumonics PM-800 excimer, Omnichrome model 2074 He-CD, Cyonics model 2201nAr+, Lexel Frequency doubled Ar+, Spectra Diode Labs SDL-2362 NIR diode lasers, 2-PMS model LPS He-Ne greenie lasers, several instrument-contained red diode lasers.  Other: Several floating laser tables, J-Y Dilor Model LabRAM Raman Spectrometer, in-house built SPR instrument, DRE High Precision Ellipsometer, 2 Princton Instruments imagining spectrometers (each contains Acton SpectroPro-275 monochromator equipped with TEAC TE cooled CCD detectors), Focused ion beam (FIB) milling instrument, 3 Cooke Vapor deposition systems, Brewster Scientific Spin Coater, HP capillary electrophoresis instrument and two modular CE systems. Three independent MCA systems including zoom video microscopes, diode lasers (some VCSELs), position sensitive detectors, optical rails, programmable syringe pumps and signal processing equipment are available in the SERF laboratory.

Other Resources:  The UT Department of Chemistry operates well-equipped Mass Spectrometry, NMR and Polymer Characterization Centers and possesses substantial equipment for vibrational spectroscopy.  In addition, well staffed machine, glassblowing, and electronic shops are available at a nominal charge at UT and ORNL.   A Virteck Chipwriter Professional Arrayer model SDDC-2 with ChipWriterPro and CloneTracker2 Software is available for depositing phases in arrays.  Surface and microscopy equipment at UT within the SERF building attached to Chemistry includes Perkin Elmer 5500LS XPS with a non-monochromatized Mg Kα X-ray excitation source, Hitachi 4300SE/N and Hitachi 3500SE SEMs, Hitachi H-800 TEM, Asylum Research MFP-3D AFM and others.  A JEOL JBX-6000S/E e-beam writer is available for use and crucial to the proposed studies.  The DOE sponsored Center for Nanophase Material Science (CNMS) is being established at ORNL. Dr. Sepaniak and his students have maintained access to ORNL facilities.
