| ABSTRACT: Exciting research discoveries in nanoscience and nanotechnology have been occurring at an explosive rate. However, for these "laboratory" discoveries to have an impact on a commercial scale, critical barriers to achieving high volume, high rate processing at the nanoscale, or "nanomanufacturing", must be overcome. Nanomanufacturing can be generally defined as the fabrication and assembly of nanoelements (e.g., nanoparticles, nanofillers, nanotubes, nanofibers, nanowires) into nanostructures, devices, and systems - and integration into larger scale structures - such that heterogeneity, specificity, and scalability is possible. The barriers to nanomanufacturing include challenges such as understanding differences in material behavior at the nanoscale under manufacturing conditions such as high shear rates, and rapid variations in temperature and pressure; precision control of movement and registration; precision spatial and temporal control of process conditions such as temperature; heterogeneous patterning and assembly over large areas; robustness of templates and assemblies; detection and minimization of defects; and on-line measurement of properties and process conditions. This talk will discuss examples of these challenges with respect to various nanomanufacturing approaches, with the intent of stimulating the discussion of opportunities for fundamental advancements in intelligent controls. | |

| Julie Chen is currently the Director of the Nanomanufacturing Center of Excellence at the University of Massachusetts Lowell, where she is a Professor of Mechanical Engineering and is also co-Director of the Advanced Composite Materials and Textile Research Laboratory. Dr. Chen was the Program Director of the Nanomanufacturing Program and of the Materials Processing Program in the Division of Design, Manufacture, and Industrial Innovation at the National Science Foundation from 2002-2004. She received her PhD, MS, and BS in Mechanical Engineering from MIT. Dr. Chen has been on the faculty at Boston University, a NASA-Langley Summer Faculty Fellow, a visiting researcher at the University of Orleans and Ecole Nationale Superieure d'Arts & Metiers (ENSAM-Paris), and an invited participant in the National Academy of Engineering, Frontiers of Engineering Program. In addition to co-organizing several national and international symposia and workshops on nanomanufacturing and composites manufacturing for NSF, ASME, ASC, and ESAFORM, Dr. Chen has also served on editorial boards, advisory committees, and review panels for several journals and federal agencies. |
