Ion Segregation in Aqueous Solutions [PDF]
The Journal of Physical Chemistry B, 2012 Microscopic structures and dynamics of aqueous salt solutions were investigated with the ultrafast vibrational energy exchange method and anisotropy measurements. In KSCN aqueous solutions of various concentrations, the rotational time constants of SCN(-) anions are proportional to the viscosities of the solutions.

Phase Segregation in Cerium−Lanthanum Solid Solutions [PDF]
The Journal of Physical Chemistry B, 2006 Electron energy-loss spectroscopy (EELS) in combination with scanning transmission electron microscopy (STEM) reveals that the La enrichment at the surface of cerium-lanthanum solid solutions is an averaged effect and that segregation occurs in a mixed oxide phase.

Entropy-Driven Grain Boundary Segregation: Prediction of the Phenomenon
Metals, 2021 The question is formulated as to whether entropy-driven grain boundary segregation can exist. Such a phenomenon would be based on the assumption that a solute can segregate at the grain boundary sites that exhibit positive segregation energy (enthalpy ...

Grain boundary segregation and precipitation in an Al-Zn-Mg-Cu alloy [PDF]
MATEC Web of Conferences, 2020 High strength Al-alloys are highly susceptible to intergranular embrittlement, which severely limits their lifetime. This article summarizes our recent work on the effect of solute segregation in the precipitation behavior at grain boundaries (GBs ...

Journal of Materials Research and Technology, 2023 Twin boundaries (TBs) are effective sinks for solutes to segregate, as they may drive the structural transformation and therefore tailor the properties of magnesium alloys. In this study, a systematic investigation on the TB segregation energy (Eseg) has

Analytical solutions of the segregation problem [PDF]
MATEC Web of Conferences, 2018 New analytical solutions of the segregation problem were found. The segregation is caused by the dissolved gas displacement by a moving crystallization front. The displacement is caused by the low solubility of the volatiles in solid, so the dissolved gas is withdrawn from the crystallizing melt towards the surrounding melt.
