Gieseking Receives NSF CAREER Award

Figure from Rebecca GiesekingRebecca Gieseking, Assistant Professor of Chemistry, has received an NSF CAREER award from the Chemical Theory, Models and Computational Methods program. This award will enable her research group to develop computational models that provide chemical understanding of how light interacts with metal nanoclusters.

Harnessing solar energy is crucial to reduce humanity’s dependence on fossil fuels and alleviate the environmental impact of our ever-increasing demand for energy. Noble metal nanoclusters containing tens to hundreds of metal atoms have the potential to revolutionize solar energy technologies by harnessing light to produce chemical fuels. These nanoclusters strongly absorb light because they support plasmons, which are collective oscillations of the electrons. Understanding, controlling, and manipulating the plasmon properties is key to improving the efficiency of solar energy storage.

Rebecca has shown that efficient computational models can accurately model the light absorption of metal nanocluster, and her group is now extending these models to understand the decay processes after metal nanoclusters absorb light. They are using these models to understand how these decay processes change as a function of nanocluster size, shape, and composition to design metal nanoclusters with controllable decay time scales for efficient solar energy storage.
