Teaching and Learning the Design, Development and Evaluation of Sustainable Materials Selection and Processes
R. D. Sisson*, J. O'Shaughnessy, K. Rong, J. Bergendahl, D. Apelian,Worcester Polytechnic Institute, USA

Abstract
In the competitive global innovation economy of the 21st century there is need for engineers with the education, experience and inclination to design, develop and evaluate green manufacturing processes. Over the past ten years at WPI we have been incorporating important environmental issues into several graduate and undergraduate engineering courses. Our first course was a graduate course on environmental issues in manufacturing engineering that was team taught by environmental and materials engineers with a focus on toxic use and energy consumption. In addition, the undergraduate course in materials processing was modified to include evaluation of the sustainability and robustness of the processes. Recently several new courses have been developed in sustainability as well as materials processing. A new course in "Making theWorld: Engineering for Sustainable Development" has recently been developed as part of the Great Problems Seminar for first year students. In this paper the results of these efforts will be presented in terms of best practices as well the results of several student projects.

Paper Presented:

Production of Novel Architectures through Controlled Degradation of Electrospun Precursors

X. Dai*, S. Shivkumar,WPI, USA

Abstract
The use of organic and inorganic precursors for the production of metal oxides with controlled archtecture has received considerable attention in recent years. The morphology and the crystallinity in the oxide can also be controlled by tailoring the conditions used during the pyrolysis of the precursor. In this contribution, various precursors including organometallics, monomers, polymers, copolymers, inorganic compounds and their mixtures have been electrospun to yield fibrous templates with fiber diameters in the 100 to 500 nm range. This electrospun structure is pyrolyzed at temperatures between 500 to 700C to yield solid or hollow fibers of oxides or metal-oxide mixtures. Such structures may be highly suitable for many applications including orthopedic and dental implants, catalysis membranes, sensors and drug delivery devices.
