Summary: The solidification of AgCo, AgNi, and AgCu nanodroplets in the size range of 2-8 nm was studied using molecular dynamics simulations. Despite the surface segregation of Ag in the bulk solid, the simulations revealed clear differences in the solidification pathways. AgCo and AgNi separate in the liquid phase and solidify close to equilibrium, while AgCu remains in a kinetically trapped state and solidifies in one step. An analytical model was used to rationalize these differences and analyze the size dependence of solidification temperatures.

Summary: The influence of the solvent on the reaction between dysprosium(III) chloride hydrate and the N3O2 ligand H2L was investigated. A new mononuclear chloride complex [Dy(L)Cl(H2O)(2)] was isolated in ethanol, indicating no hydrolysis of the ligand. In contrast, a similar reaction in methanol resulted in partial hydrolysis of the Schiff base and the formation of a new hemiacetal donor. The magnetic characterization of the chloride complex showed field-induced single ion magnet behavior with a thermal energy barrier of 113.5 K, the highest reported for dysprosium complexes derived from H2L.
