Adsorption of FFA, Soap and Glycerine in Biodiesel Using Magnesium Silicate

open access: yesChemical Engineering Transactions, 2015
The effect of SiO2/MgO molar ratios of magnesium silicate on adsorption of free fatty acid (FFA), soap and glycerine in biodiesel was studied. The magnesium silicate adsorbent was prepared by the precipitation of magnesium sulfate and sodium metasilicate.

Synthesis of magnesium silicate from wheat husk ash: Effects of parameters on structural and surface properties [PDF]

open access: yesBioResources, 2012
In the present study, magnesium silicate was produced by using wheat husk ash. Wheat husk was burned at 600 °C to obtain an amorphous ash structure, and the ash was processed with sodium hydroxide solution with heat to extract silica.

Concomitant Effect of Quercetin- and Magnesium-Doped Calcium Silicate on the Osteogenic and Antibacterial Activity of Scaffolds for Bone Regeneration

open access: yesAntibiotics, 2021
Quercetin is a bioflavonoid which has a broad spectrum of biological activity. Due to its lower chemical stability, it is usually encapsulated, or a metal–quercetin complex is formed to enhance its biological activity at a lower concentration.

Computer simulations of iron in magnesium silicate perovskite [PDF]

open access: yes, 2008
We use atomistic computer simulation techniques to investigate the site partitioning of iron in (Mg,Fe)SiO_{3} perovskites. Our calculations predict that the most energetically favourable reaction for iron substitution will be a direct exchange of Fe^{2+}

Dust absorption and scattering in the silicon K-edge [PDF]

open access: yes, 2019
The composition and properties of interstellar silicate dust are not well understood. In X-rays, interstellar dust can be studied in detail by making use of the fine structure features in the Si K-edge.

Formation, Structure and Properties of Modified with Forsterite Microarc Oxidation Coating on Мл10 (ML10) Magnesium Alloy

open access: yesМеханика машин, механизмов и материалов, 2022
The structure, phase composition, microhardness, and adhesive strength of a coating on an МЛ10 (ML10) magnesium alloy modified with Mg2SiO4 forsterite during microarc oxidation (MAO) have been studied.

Tribocorrosion Properties of PEO Coatings Produced on AZ91 Magnesium Alloy with Silicate- or Phosphate-Based Electrolytes [PDF]

open access: yes, 2018
In this work, the tribocorrosion behavior of plasma electrolytic oxidation (PEO)-coated AZ91 samples was studied. In particular, two different coatings were produced and compared. One was obtained with an alkaline electrolyte containing sodium phosphate,

Growth of Self‐Assembling Tubular Structures of Magnesium Oxy/Hydroxide and Silicate Related With Seafloor Hydrothermal Systems Driven by Serpentinization

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Tubular structures self‐assemble from precipitating magnesium salts under the chemical garden chemobrionic growth process. Two experimental procedures, the dissolution of magnesium salt pellets and the injection of magnesium salt solutions into silicate ...

Structure, bonding and morphology of hydrothermally synthesised xonotlite [PDF]

open access: yes, 2009
The authors have systematically investigated the role of synthesis conditions upon the structure and morphology of xonotlite. Starting with a mechanochemically prepared, semicrystalline phase with Ca/Si=1, the authors have prepared a series of xonotlite ...
