Thermal Storage, Transport and Measurements Spanning Energy Technologies to Biology

This seminar presents topics of current experimental research in my group with the common theme of thermal transport. The physics of heat conduction dominated by surfaces is an enduring and critical area of research, impacting thermoelectric energy conversion and applications across the semiconductor industry. I will discuss new experimental insights that are modifying long-held perceptions on how phonons interact with surfaces. Further, I will discuss experiments probing fundamental heat to electricity energy conversion in the two-dimensional materials where measurements of the Seebeck coefficient provide unique insight into charge transport not available through typical current-voltage characteristics. In the second part of the talk, I will discuss research on components for heat transfer, heat exchangers and heat pipes, that are made of plastic. Materials for thermal storage are critically needed for reducing greenhouse gas emissions. Here, I will discuss our current work on thermophysical and thermochemical heat storage. Finally, I will describe our nascent efforts at intracellular thermometry of neurons with the aim of understanding connections between their biochemistry and thermodynamics.

Sanjiv Sinha is an Associate Professor and the Associate Head for Undergraduate Programs in the Mechanical Science and Engineering Department at the University of Illinois at Urbana-Champaign (UIUC). His research interests are in fundamental thermal and electrothermal transport, nanoscale thermometry and thermal energy systems.
