DOI: 10.1016/j.ijheatmasstransfer.2020.119474
Abstract: Abstract Solute segregation of carbon dioxide in water during entrapment of a bubble by a solidification front is numerically investigated. The bubble can be initiated by supersaturation ahead of the solidification front. Porosity influences not… read more here.

DOI: 10.1039/d0nr07180c
Abstract: Nanocrystalline (NC) metals suffer from an intrinsic thermal instability; their crystalline grains undergo rapid coarsening during processing treatments or under service conditions. Grain boundary (GB) solute segregation has been proposed to mitigate grain growth and… read more here.
