Abstract:
The ability to locally engineer materials architecture as well as materials composition enables achieving properties that are not readily attainable otherwise. Additive manufacturing enables producing complex geometries such as cellular solids with site-specific composition. In addition, directed growth and self-organization of nanostructures is emerging as an attractive route to create hierarchical materials having both composition- and geometry-derived mechanical properties. What is more, the fundamentals of these advanced bottom-up manufacturing processes can be extended to the more conventional areas of surface engineering and repair applications.

In this talk, I will highlight different examples of how advanced manufacturing and surface engineering can be used to achieve properties that deviate from conventional processing routes. I will discuss 3D printing biocompatible, compliant constructs for bone implant applications. I will also show how self-assembly of carbon nanotubes in combination with conformal coating techniques can be used to create bulk materials with widely tunable properties. Finally, I will demonstrate how the life-span of materials can be extended by resetting the microstructural mechanisms leading to damage.  I will conclude by discussing the challenges and new opportunities in materials design and recovery enabled by advanced manufacturing.

Bio:
Dr. Atieh Moridi is currently a postdoctoral researcher in the Departments of Mechanical Engineering and Materials Science and Engineering at the Massachusetts Institute of Technology (MIT). She was awarded PhD Cum Laude (the highest institute honors) in Mechanical Engineering at Politecnico di Milano, Italy in 2015. She received her BSc and MSc from Sharif University of Technology, Iran. Her research interests lie in the areas of surface engineering, advanced materials and manufacturing. She applies theories from different fields to the multi-faceted studies of materials and manufacturing.
