The molal solubility for nano zinc oxide (ZnO)  , copper (2%) doped ZnO , Fe(2%) doped ZnO , Ti(2%) doped ZnO , Ag (25) doped ZnO  in 50%DMF and 50% DMSO, (v/v), volume to volume were measured at 293.15, 303.15 , 313.15, 323.15K .
The thermodynamic parameters, Gibbs free energy of solvation, enthalpies and entropies of solvation were evaluated for nano zinc oxide and nano zinc oxide doped from the solubility measurements. These thermodynamic parameters explain the effect of doping elements on the thermodynamic behviours of nano zinc oxide in solvation process. 

Contribution/ Originality
This paper uses the thermodynamic parameters for discussing the solubility behaviour because few studies is finding for nano particles solvation explanation.
