Presentation Summary

  • Introduction to the concept of solar thermal fuels; discussion of previous efforts and the challenges they identified.
  • Discussion of the principles behind our design strategy and the methods we use to develop and test these principles.
  • Presentation of our first-principles results for energy storage capacity and lifetime of the designed azobenzene-derivitized carbon nanotube (azo/CNT) solar thermal fuels.
  • Presentation of preliminary experimental results for synthesis and characterization of azo/CNT solar thermal fuels.
  • Discussion of extension of strategy to numerous other chromophore/template nanostructures.

Speaker Biography (Alexie Kolpak)

Alexie Kolpak obtained a B.A. in Biochemistry and a Ph.D. in Physical Chemistry at the University of Pennsylvania. She went on to do a postdoc in Applied Physics at Yale University before starting her current position as a postdoc with Jeffrey C. Grossman in the Department of Materials Science and Engineering at MIT. Her research interests include photocatalysis and photovoltaics, solar thermal fuels, complex oxide heterostructures, surface and interface phenomena, and first-principles materials design.

Company Profile (MIT - Department of Materials Science)

The Department of Materials Science at MIT, in the group of Jeffrey C. Grossman, employs theoretical and computational modeling tools to understand the physical and chemical properties of materials all the way from the atomic- to the macroscopic-scale. We apply this knowledge to design and optimize novel materials and systems with enhanced properties that will enable wide-spread adoption of solar energy storage and conversion technologies.
