Phase Diagram Determination of (2-Amino-2-Methyl-1, 3-Propanediol) AMPL-TRMP (Trimethylolpropane) Binary System
Organic "Plastic Crystal" Thermal Energy Storage (TES) Materials are characterized by unusually large entropies of solid-solid transition compared to their entropies of fusion. In this research program, we investigate the thermal behavior of a binary AMPL-TRMP system and develop a …
