Nanostructure-enhanced phase change materials (NePCM) represent a new class of thermal storage substances composed of colloidal dispersions in the nano-size range. Faculty member Jay Khodadadi, Alumni professor in the Department of Mechanical Engineering, is conducting research that focuses on thermal conductivity enhancement of alkanes – commonly called paraffins – by introducing various metallic nanoparticles. Since 2009, the U.S. Department of Energy has supported a $2.5 million project in the state of Alabama, with Auburn playing a lead role in the development, characterization and testing of these materials.

Development and refinement of direct or waste heat utilization technologies are of particular interest give the fluctuating price of petroleum. Phase change materials (PCM) have been used for centuries for storage of thermal energy and its utilization at a later time. NePCM could have utility in heat exchangers, building materials, food storage and thermal comfort, as well as thermal management of electronics, textiles, air conditioning and transportation applications.
