August 18, 2008 Professor Yi Guo Awarded a Research Grant by the NSF
The National Science Foundation (NSF) newly awarded Stevens Professor Yi Guo with a grant to research the "Control of Atomic-Scale Friction by Normal Surface Oscillation."
The goal of the NSF project is to develop control methodologies to reduce friction at the atomic-scale by surface vibration. Professor Guo plans to pursue a rigorous mathematical understanding of the effect of normal surface oscillation on friction, and to develop control methods to quantitatively adjust vibration parameters. She also plans to validate the analytic results through atomic force microscopy (AFM) experiments. To achieve the research goal, she will hire a graduate research assistant, and work closely with collaborators at Oak Ridge National Laboratory, who have extensive experience on atomic-scale friction and AFM.
