Well, I don't know... is there really a lack of research? Within petrophysics, these topics are basics for many applications and well published.

Today exists high accuracy models for prediction of thermodynamics properties e.g. equations of state. highly accurate models for thermal conductivity of fluids are very rare. for solids most of the available data are experimental (which is good) but do not cover wide range of temperatures.
