Viscosities were measured for the ternary systems Y(NO3)3+La(NO3)3+H2O, La(NO3)3+Ce(NO3)3+H2O, and La(NO3)3+Nd(NO3)3+ H2O and their binary subsystems Y(NO3)3+H2O, La(NO3)3+H2O, Ce(NO3)3+H2O, and Nd(NO3)3+H2O at 293.15, 298.15 and 308.15 K. The results were used to test the applicability of simple equations for the viscosity of the mixed solutions. The predictions agreed well with measured values, implying that the viscosities of the examined electrolyte solutions could be related to those of their constituent binary solutions using these simple equations.

Morphology of NaNdF_4 nanocrystals from Nd(C_3H_7COO)_3·Phen and Nd(NO_3)_3·Phen (Phen,1,10-phenanthroline) as neodymium precursors

A series of NaNdF4 nanocrystals was synthesized via a facile hydrothermal route with Nd(C3H7COO)3·Phen and Nd(NO3)3·Phen (Phen,1,10-phenanthroline) as the Nd precursors.Distinct effect of the neutral donor ligand (Phen) on the morphology of NaNdF4 nanocrys-tals was demonstrated.When Nd(C3H7COO)3·Phen was chosen and the hydrothermal reaction temperature was controlled at 220 ℃,the NaNdF4 nanocrystals with uniform short nanorod shape were obtained.The sizes of the as-prepared nanorods could be tuned by changi...
