I am looking to characterise the themodynamic properties of the thiospinel mineral carrollite (CuCo2S4) in order to conduct a theoretical thermodynamic modelling exercise. I have well characterised carrollite mineral specimen, and need to find a laboratory that can test this mineral phase for its entropy, enthalpy, Gibbs free energy etc. Any ideas on which laboratories/research groups conduct this type of work (e.g., adiabatic calorimetry), and which would be the best one to approach?
