Energy & Water
Energy & Water
Two of the most pressing grand engineering challenges of our time include harnessing energy from new sources and increasing access to clean water. The Energy and Water, E&W, focus area concentrates on both the fundamental science around energy and water and on translating E&W discoveries into practical applications. We leverage our existing strengths in materials synthesis, such as polymers, quantum dots, nanoplates, and 1D/2D materials, via collaborative interactions with other departments such as Physics, Math, Chemistry, Biology, and Environmental Science & Engineering. Some of our most transformative work focuses on photonic solar cells, photovoltaic polymers, nanowire devices, computational methods, and 2D materials.
