“Nanocalorimetry of Materials Confined to Small Dimensions”

Leslie Allen
Materials Science Department
University of IL at Urbana
 
ABSTRACT
Properties of materials confined to the small size scales are particularly interesting because they can be dramatically different than those observed in bulk form and they can be analyzed on time scales much faster then with bulk techniques.  In this talk I discuss thermal analysis using new instrumentation and research results of materials at the small and fast scales.  The discussion includes studies of thin films, nanoparticles, and liquids at a size scale far smaller than conventional calorimetry.  I will include research topics such as size-dependent melting point depression, magic number nanoparticles, thickness-dependent glass transition temperature, phase transitions of 2D and 3D self assembled monolayers, and preliminary protein analysis of micro-liter samples.
