Chengzhe Zhou Receives 2020 Richard B. Chapman Memorial Award

06-11-20

Chengzhe Zhou, a graduate student in Physics supervised by Professor Sandra Troian, is a recipient of the 2020 Richard B. Chapman Memorial Award. His doctorate research focuses on the development of novel theoretical and computational tools for quantifying the nonlinear evolution and control of moving liquid boundaries driven by external fields. He hopes his findings offer new and useful analytic tools for investigating emergent small-scale dynamic phenomena in strongly driven nonlinear systems. The Richard B. Chapman Memorial Award is given to an EAS graduate student in hydrodynamics who has distinguished himself or herself in research.

Experiments Settle Long-Standing Debate about Mysterious Array Formations in Nanofilms

05-19-11

Sandra M. Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, and colleagues' experiments have confirmed which of three possible mechanisms is responsible for the spontaneous formation of three-dimensional (3-D) pillar arrays in nanofilms (polymer films that are billionths of a meter thick). "My ultimate goal is to develop a suite of 3-D lithographic techniques based on remote, digital modulation of thermal, electrical, and magnetic surface forces," Troian says. Confirmation of the correct mechanism has allowed her to deduce the maximum resolution or minimum feature size ultimately possible with these patterning techniques. [Caltech Press Release]

Sandra Troian and Mathias Dietzel Solve Decade-Long Mystery of Nanopillar Formations

10-23-09

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]
