S3. Use of Thermal Energy for Electrical Power Generation and Refrigeration: Fundamental Science, Materials Development and Devices
Thermal energy has been used in a variety of ways in electrical power generation and refrigeration under both transport and equilibrium conditions. This symposium targets technologies that use thermal energy and the fundamental science that enables it. Specific technologies of interest incluse thermoelectrics, thermophotovoltaics, electro-, magneto- and baro-caloric systems, Stirling and thermoacoustic engines. The challenges to implementation or improvement have been materials specific. The approaches of interest include novel material development, measurement standardization, bonding, ceramic processing, crystal chemistry, modeling, nanostructured materials, devices, and others.
The symposium also aims to include the basic science underlying behavior of such materials. Fundamental physics include phonon transport and interactions in solids, in nanosystems, and across interfaces. Abstracts are encouraged on topics including, but not limited to, coherent phonon transport, non-local phonon conduction around interfaces, phonon interference, the interplay between material structures and intrinsic phonon scattering mechanisms, and how these processes relate to the thermal conduction mechanisms in solids and across interfaces.
This symposium encourages contributions on topics outside the technologies summarized above that take advantage of thermal energy for electrical power and refrigeration. This symposium is a forum for discussing defect chemistry, conductivity, thermal conductivity optimization, caloric effects and applications for novel conversion systems. It aims to increase interaction between communities that normally work separately.
