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 ...

The three phases of galaxy formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2018
We investigate the origin of the Hubble sequence by analysing the evolution of the kinematic morphologies of central galaxies in the EAGLE cosmological simulation. By separating each galaxy into disk and spheroidal stellar components and tracing their evolution along the merger tree, we find that the morphology of galaxies follows a common evolutionary

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).

Structure of the interlayer between Au thin film and Si-substrate: Molecular Dynamics simulations

open access: yesMaterials Research Express, 2020
Interaction between 2, 3, 5 and 7 atomic layers of gold and a (111) silicon surface was investigated with the molecular dynamics simulation method. The simulation of the diffusion interaction between gold and silicon in the temperature range 425–925 K ...
