Top view of polymer film undergoing shaping process: red = warmer surface temperature, blue = cooler surface temperature.
Sandra Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, and Dr. Mathias Dietzel have uncovered the physical mechanism by which arrays of nanoscale pillars can be grown on polymer films with very high precision, in potentially limitless patterns. "This is an example of how basic understanding of the principles of physics and mechanics can lead to unexpected discoveries which may have far-reaching, practical implications," said Ares Rosakis, Division Chair and Theodore von Kármán Professor of Aeronautics and Mechanical Engineering at Caltech. "This is the real strength of the EAS division." [Caltech Press Release] [video] [Download real player]
