Vibrational Spectroscopy Laboratory

The Vibrational Spectroscopy Laboratory houses several modified infrared and Raman spectrometers which are able to accommodate unconventional sample types. Spectroscopic analysis software, developed in house, extends the laboratory's commercial modeling packages to facilitate spectral comparisons and lends insight into the static and dynamic behavior of polymer chains.

Rheology Laboratory

Equipment located in the Rheological Facility measures the steady state and dynamic response of polymers undergoing shear. 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.

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

Nanoimprint Lithography Laboratory

Nanoimprint lithography (NIL) is a new way of nanopatterning and a revolutionary solution to nanomanufacturing. NIL patterns nanostructures by the physical deformation of a deformable material using a mold. NIL can have sub-5 nm resolution and 1% CD control, and simultaneously achieve high-throughput, sub-10 nm structures and low cost -- a feat currently impossible using other existing lithographic methods.

The Nanonex NX-2000 is a single wafer nanoimprinter for all forms of imprint (e.g. thermal, photo-curable, and embossing) without alignment. The tool offers excellent uniformity regardless of the roughness of the backside of the substrate and mold, minimum relative lateral shift between the wafer and mold, very small thermal mass and hence rapid heating and cooling time.
