Jonathan W. Bender
Assistant Professor
Professor Bender's field of research focuses on nanotribology, which is the science and engineering of friction and wear between rubbing interfaces probed at the nanometer scale. Continued progress in areas as diverse as microelectromechanical systems, artificial joints, continuously variable transmissions, storage media, and suspension rheology depends on our ability to explore sliding contacts having nanometer dimensions. Our research focuses on using state-of-the-art surface probe microscopes and quartz crystal resonators to explore the frictional and mechanical aspects of well-characterized surfaces in single-point contact. Examples include using a scanning tunneling microscope under ultra-high vacuum to probe the friction and wear of pristine metal surfaces exposed to well-controlled environments, atomic and colloidal force microscopes to characterize sliding contact under lubricated conditions, and QCM techniques to probe surface activity of tribological agents. Our goal is to gain insight into the mechanisms of the macroscopic tribological response from the study of well-characterized contacting nano-scale surfaces.
