The group laboratory space is 420 ft2 and dedicated to research activities. It contains a 4 foot fume hood, gas, water, and vacuum lines. There are five seating stations and six PC's available to search literature, collect and analyze data, and prepare scientific posters, reports, contribute to manuscripts for publication, etc. In addition to the equipment and instrumentation listed below, there is shared-access to other instrumentation available in the Chemistry Department.
Synthesis
Chemicals High-purity chemicals are stored in a desiccator cabinet. Desiccator cabinet
Analytical Balance Solid state methods (conventional solid state, ceramic, sol gel, sealed tube, solvothermal, etc.) require careful control of reagent amounts, which are typically weighed to 0.0001 g. Analytical Balance
Agate Mortar and Pestle An agate mortar and pestle is used to grind samples prior to a reaction. Mortar and Pestle
Furnaces High temperature furnaces heat samples in the conventional solid state synthesis method. Temperature ranges are from ambient temperature up to 1100 C with five Barnstead Thermolyne 47900 box furnaces with metal coil heating elements, 1200 C with two ModuTemp furnaces with SiC elements, and 1700 C with a Barnstead Thermolyne 46100 using MoSi2 elements. High form alumina crucibles are used to contain samples at these reaction temperatures. A vacuum furnace is also available for drying reagents. Furnace

Resistance Measurements A Keithley Electrometer 2002 or 6517a is used to measure the resistance of solids from room temperature to 1100 C, or from room temperature to near liquid nitrogen temperature (77 K). Temperature is monitored using a thermocouple attached to a USB-TC. The instrument is interfaced using a GPIB-USB converter and data is collected using a custom built VI controlled with Labview.
