Insights into the Nature of Eutectic and Deep Eutectic Mixtures [PDF]

open access: yesJournal of Solution Chemistry, 2018
A stricter definition of a deep eutectic solvent (DES) is urgent, so that it may become a sound basis for further developments in this field. This communication aims at contributing to deepening the understanding of eutectic and deep eutectic mixtures concerning their definition, thermodynamic nature and modelling.

Nonisothermal eutectic crystallization

open access: yesPhysical Review E, 1996
A model for the dynamics of nonisothermal eutectic growth is examined in the limit of a spatially uniform but time dependent temperature field. The simpler case of nonisothermal growth is first considered, and approximate solutions are obtained for the crystallization rate for the growth of a single crystallite and for homogeneous nucleation.

Influence of Solidification Parameters on the Amount of Eutectic and Secondary Arm Spacing of Al–7wt% Si Alloy Solidified under Microgravity

open access: yesCrystals, 2022
During the solidification of hypoeutectic Al–7% Si alloy, density differences develop in the melt due to variations in concentration and temperature. On Earth, melt flow can occur due to gravity, which then affects the solidification process.

Fabrication and Characterization of K2CeCl5/6LiCl and CeCl3/SrCl2/6LiCl Eutectics for Thermal Neutron Detection

open access: yesCrystals, 2022
In recent years, thermal neutron detection using scintillators has been used in a wide range of fields. Thus, the development of scintillators with a higher light yield, faster decay, and higher sensitivity for thermal neutrons is required. In this study,

Presolidification in Eutectic Droplets

open access: yesPhysical Review Letters, 2023
Evidence of presolidification, the counterpart to premelting, is reported. Near the eutectic temperature, T_{C}, the propagation direction of thermal gradient driven motion of eutectic Ge-Pt droplets on Ge(110) is determined by presolidification.
