Groundbreaking research could ignite new solutions to heat transfer in nano-devices

Timothy D. Sechler, an undergraduate student at The University of Scranton's Dexter Hanley College for adult students.

"This project gave me the opportunity to see what my future would be like if I pursue a research track," said Mr. Sechler, a junior who now plans to pursue a Ph.D. in chemistry.

The research used vibrational spectroscopy with picosecond time resolution to monitor the flow of energy across surfactant molecules that separate droplets of confined water from a nonpolar liquid phase. Their research shows that the surfactant layer must be analyzed in terms of its vibrational couplings, rather than by ordinary heat conduction. Their research provided the first detail of the precise pathways for interfacial vibrational energy in both time and space resolution.

The paper, entitled "Vibrational energy transfer across a reverse micelle surfactant layer," will be published in the October 15 issue of Science, the prestigious journal of the American Association for the Advancement of Science, and on the Science Express Web site on Sept. 23, 2004.
