This would include thermodynamics of nano structures, of elemental electronic components, and of individual macro molecules.
This would include thermodynamics of entire organelles like mitochondria and muscle fibers, and thermodynamics of extremely complex system like entire animals or plants and of an ecosystem building on the ability of thermodynamics to extract a few crucial parameters from a huge chemical soup.
By this I mean the use of thermodynamics in the entire chain from designing a molecule with particular properties, suggesting a practical path of synthesis, through designing the process equipment, to analysis of stability and control of the process. Generating reliable property data, experimentally as well as theoretically, is a crucial part of this.
This covers foundations of thermodynamics, new definitions of "old" quantities, connections to statistical mechanics, generalized entropy, chaos, and complex systems, teaching of thermodynamics, and much more.
