Prof. Sara Skrabalak
The importance of molecular structure to molecular function is a central tenet in chemistry, with the lock-and-key model of enzyme activation representing a classic example. Likewise, the function of inorganic nanomaterials depends on structural parameters that include crystallite size and shape as well as architecture. To realize the function of such materials, these structural parameters must be precisely controlled and the Skrabalak group is developing the synthetic toolkit to achieve advanced nanostructures. This seminar will highlight seed-mediated co-reduction as a route to structurally defined bi- and trimetallic nanomaterials, hierarchical materials, and intermetallic compositions. These synthetic advances are enabling previously unimagined nanostructures to be accessed with new function for applications in chemical sensing and catalysis. Ultimately, understanding the relationship between nanostructure form and function will allow this relationship to be inverted to achieve materials by design. Still, the synthetic toolkit must exist to realize this vision and achieve nanomaterials on demand.
