Notice of the University Oral Examination for Ms. Paige Wilson on Friday, April 26 at 1 p.m. in H301 (Head Hall).

"Electrochemical Monitoring of Oxide in Molten Salts"

The miniaturization of devices like heat exchangers, power electronics, and motors has boosted performance but increased heat generation in electronic systems. Effective heat management in engineering systems necessitates exploring polymer nanocomposites for heat transfer. This study examines the thermal conduction in carbon nanotube (CNT) and thermoplastic polyurethane (TPU) polymer nanocomposites, focusing on sample preparation, filler weight fraction, and load transfer’s impact on thermal conductivity. The Transient Plane Source (TPS) method is evaluated for accurate results in measuring thermal conductivity. Characterization includes scanning electron microscopy, scanning transmission electron microscopy, dynamic mechanical analysis, and energy-dispersive X-ray spectroscopy. Results indicate 265% increase in thermal conductivity with 10 wt% filler. Various models were studied concluding that classic models fall short in accurately predicting the thermal conductivity due to inability to account for the characteristics of nanoscale particles. The Deng model emerges as a standout candidate for predicting thermal conductivity without necessitating modifications.

Everyone is welcome to attend.
