Eutectic colony formation: A phase field study [PDF]

open access: yesPhysical Review E, 2001
Eutectic two-phase cells, also known as eutectic colonies, are commonly observed during the solidification of ternary alloys when the composition is close to a binary eutectic valley.

Effect of an Aluminosilicate Disperse Additive on Behaviors of Autoclave Silicate Materials

open access: yesBuildings, 2021
In this research, a phase formation in CaO–SiO2–Al2O3–H2O binding system under hydrothermal conditions was studied. The novelty of this article lies in the quantitative full-profile X-ray diffraction (XRD) analysis used to determine kinetics of mineral ...

Two-phase galaxy formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We propose and test a scenario for the assembly and evolution of luminous matter in galaxies which substantially differs from that adopted by other semianalytic models. As for the dark matter (DM), we follow the detailed evolution of halos within the canonical LCDM cosmology using standard Montecarlo methods.

Morphology, phase and chemical composition of the nanostructures formed in the systems containing lanthanum, cerium, and silver

open access: yesХімія, фізика та технологія поверхні, 2021
  X-ray phase and thermogravimetric analysis, scanning electron microscopy and energy-dispersion spectroscopy were used to study the products of phase formation during the precipitation of lanthanum and cerium salts in the presence of silver nitrate ...

Phase Separation Drives Heterochromatin Domain Formation [PDF]

open access: yesBiophysical Journal, 2017
Constitutive heterochromatin is an important component of eukaryotic genomes that has essential roles in nuclear architecture, DNA repair and genome stability, and silencing of transposon and gene expression. Heterochromatin is highly enriched for repetitive sequences, and is defined epigenetically by methylation of histone H3 at lysine 9 and ...

Features of the Phase Formation of Cr/Mn/Fe/Co/Ni/Cu Codoped Bismuth Niobate Pyrochlore

open access: yesCrystals, 2023
The phase formation process of Bi2Cr1/6Mn1/6Fe1/6Co1/6Ni1/6Cu1/6Nb2O9+Δ containing 3d-ions of transition elements in equimolar quantities was studied in a wide temperature range (400–1050 °C).

Microstructures in phase-inversion membranes. Part I. Formation of macrovoids [PDF]

open access: yes, 1992
A new mechanism for the formation of macrovoids in phase-inversion membranes is proposed. It is based on the observed difference in type of demixing of a thin film of a polymer solution when immersed in a nonsolvent bath: delayed or instantaneous ...
