Unravelling the surface chemistry of metal oxide nanocrystals, the role of acids and bases [PDF]
, 2014 We synthesized HfO2 nanocrystals from HfCl4 using a surfactant-free solvothermal process in benzyl alcohol and found that the resulting nanocrystals could be transferred to nonpolar media using a mixture of carboxylic acids and amines.
