Creation of Titanium-Based Nanofoams in Reduced Gravity for Dye-Sensitized Solar Cell Production

PI: Kristen Scotti, Northwestern University - Evanston

The objective of this research includes creating and examining titanium oxide (first two campaigns) and titanium (third campaign) freeze-cast materials (which are not nanoporous, but rather exhibit directionally aligned macropores) in the microgravity environment provided by parabolic flight. Work continued under T0149.

Knowledge gained from the research may aid in the development of lightweight materials for the purpose of improved space systems, launch vehicles and payload systems. This will enhance the ability to extend and sustain human activities beyond low-Earth orbit (LEO) by creating a technology which increases the reliability and safety of access to space while also decreasing the overall costs.
