The Electron and Ion Microscopy Laboratory houses the new FEI TF20ST analytical high-resolution transmission electron microscope and the FEI Nova 200 Nanolab dual-beam scanning electron microscope/focused ion beam instrument. Recent acquisitions include a 3D local electrode atom probe tomography system, an environmental scanning electron microscope and a high resolution X-ray diffraction system, an atomic force microscope, and a UV-VIS ellipsometer. Full optical microscopy, sample preparation, and electron microscopy computer simulation facilities are available. The multi-disciplinary, multi-user laboratory emphasizes the production and characterization of nanoscale materials and devices and the transfer of technology to industry.

The Laboratory of Advanced Polymers and Optimized Materials (LAPOM) focuses on the development of materials with improved mechanical, tribological and thermo-physical properties, including thermoplastics, thermosets, composites, nanohybrids and coatings. High strength, wide service temperature range, low thermal expansivity, low static and dynamic surface friction, high adhesion of coatings to ceramic and metal substrates, high scratch, wear and mar resistance.

The Polymer Mechanical and Rheological Laboratory is engaged in investigations of interrelationships between morphology and mechanical properties through the influences of time and temperature of polymers, composites and hybrid organic-inorganic nanocomposites. A Mechanical Testing System (MTS810) equipped with an environmental chamber (-150° to 600° C), video and thermal wave imaging provide stress pattern-temperature relationships around propagating cracks and estimate residual stresses. A Torsional Rheometer provides viscolastic and rheological property evaluation. Reliability of dielectric property retention is being examined through simultaneous effects of radiation and electrical fields using thermally stimulated depolarization currents and thermoluminescence.

The Materials Synthesis and Processing Laboratory has research interests focused on the development of aerogels and other novel ceramics for dielectric, sensor and high temperature applications. A complete synthesis laboratory is available with several spin coaters for thin film development and with a BET surface area/pore size analyzer for structural characterization as well as high temperature furnaces and a critical point dryer.

The Laboratory for Electronic Materials and Devices is a cross-disciplinary laboratory performing basic and applied research on novel materials for advanced electronic devices of all kinds. The laboratory includes a Group IV molecular beam epitaxy system, a 3 MV ion beam accelerator, a comprehensive surface science system and several scanning probe microscopes. The primary areas of research include advanced dielectric materials, high electric field chemical reactions and molecular electronic devices.

The Advanced Metallic Materials Laboratory has research focused on the structure-property-processing relationships in metallic structural materials. Current investigations are in the areas of bulk metallic glasses; nanocrystalline materials; development of better aluminum, titanium and nickel alloys for structure applications; and shape memory alloys. Emphasis is on advanced processing and characterization.

The Laboratory for Moving Mechanical Assemblies is engaged in applied research on tribology (friction, wear and lubrication) of materials. Processing, structure and property interrelationships of thin film coatings and bulk materials are being studied with applications to moving mechanical assemblies, such as bearings, gears, MEMS and orthopedic implants.

The Optoelectronics and Thin Film Materials Laboratory studies the processing-structure-property relationships of compound semiconductors and oxides for applications including solar cells, light emitting diodes, thin film batteries and thin film transistors. Growth mechanisms, defects, luminescent properties, carrier transport properties and device physics are key emphases.

The Laboratory for Laser Materials Synthesis and Fabrication houses several high power (multi kilowatt) lasers, and is among the nation’s best. These lasers include 400J Nd-Yag pulse lasers with pulse shaping capabilities (Lumonics JK701 400W and Rofin Sinar Starweld 250) and a recently purchased 3000 W, Ytterbium YAG (IPG3000) laser equipped with a high speed galvanometric scanning mirror system for scanning the laser beam at extremely high speed. All lasers are equipped with 5-axis CNC workstations and fiber optic beam delivery for remote operation. This laser equipment is routinely employed in research work toward a broad understanding of interactions of lasers with materials and engineering aspects of the laser-materials interactions. Implementation of high power lasers for materials processing such as joining and surface engineering. Address fundamental issues in laser surface engineering of materials for application of this knowledge in the development of new corrosion/oxidation and wear/erosion resistant surfaces in challenging and extreme chemical and mechanical environments. Unique blend of in-situ diagnostics with post process analytical anaylsis for development of structure-property relationships in laser engineered surfaces of engineering and bio materials. Such a multi-dimensional approach has been envisioned for advanced manufacturing of the next generation materials.
