One of the greatest challenges facing mankind in the next century is energy management amidst consumption of a finite and limited amount of energy resources. Future innovation in diverse areas ranging from electronics to health is intimately tied to our ability to discover and implement cost-effective alternative energy systems that are efficient and composed of earth-abundant materials. My talk will begin by discussing fabrication routes whereby nanocarbon materials can be assembled or chemically rendered to possess characteristics appealing to diverse energy systems. This includes the synthesis and transfer of hierarchical self-assembled single-walled carbon nanotube materials into controllable, complex 3-D architectures and nanofabrication routes to graft complex chemical architectures into atomically-thin transferred graphene sheets. I will then discuss how these tunable material architectures can be utilized as bottom-up templates to build efficient energy systems. First I will discuss recent efforts to build fully solid-state and mechanically robust capacitive energy storage materials utilizing atomic layer deposition (ALD) on high surface-area aligned single-walled carbon nanotube templates. I will then discuss the use of nanocarbons as efficient templates for solar-to-fuel conversion applications, where elastocapillary forces can be utilized as a nanofabrication tool for structural design of three-dimensional carbon nanofiber templates enabling photon management and efficient device performance. Finally, I will close with a discussion of future plans specifically aimed toward the development of energy storage and conversion systems that are poised toward both energy system integration and efficiency.
Dr. Cary L. Pint is currently a Research Scientist in the Extreme Technology Research Group at Intel Labs pursuing research in the area of efficient energy devices. Cary received his Ph.D. from Rice University in 2010 and spent one year as a postdoctoral fellow at the University of California, Berkeley before joining Intel. Cary has authored nearly 40 publications in top journals, has over 10 patents submitted, is a coauthor on a book on carbon nanomaterials soon to be published, and has been the recipient or finalist for numerous national awards, including the APS LeRoy Apker Award, the Vanderbilt Prize, and the AVS Dorothy and Earl Hoffman Scholarship. Recently, Cary was also named as a “Top 30 Under 30” Rising Star in Science & Innovation by Forbes Magazine for his work on energy systems.
