Abstract:
Vein and hydrothermal - sedimentary types of magnesite from eastern Iran probably originated from ascending hydrothermal solutions. The host rocks are part of an ophiolite unit. The cryptocrystalline magnesites are very pure although they have a variable CaO/SiO₂ ratio. The magnesite is compact with a very fine and uniform texture. The mineralogy of samples of dead burned magnesites calcined at different temperatures and times are variable and can be predicted from phase equilibria studies. The textural relationships studied using scanning electron microscopy show that matrix is concentrated a

Abstract:
Ex situ mineral carbonation heavily depends on the ability of cations (e.g., Mg2+) to form stable carbonates. The abundant serpentine minerals contain sufficient magnesium to fill this role. Serpentine partially dehydroxylated by thermal pre-treatment, which has a nearly amorphous state (meta-serpentine), has been shown to enhance overall carbonation yield. However, the dissolution kinetics of meta-serpentine under the carbonic acid system remains largely unresolved within the literature.

Knowledge of the coefficient of thermal expansion (CTE) of a ceramic material is important in many application areas. Whilst the CTE can be measured, it would be useful to be able to predict the expansion behaviour of multiphase materials. There are several models for the CTE, however, most require a knowledge of the elastic properties of the constituent phases and do not take account of the microstructural features ·of the material. If the CTE could be predicted on the basis ofmicrostructural information, this would then lead to the ability to engineer the microstructure of multiphase cera

Abstract:
Anaerobic digestion is a worldwide technology to treat organic waste streams, primarily due to its capacity to produce methane as renewable energy. However, there is an increasing interest on nutrient recovery (N and P), which from both environmental and economic reasons have been identified as key feature in anaerobic digestion plants. Controlled struvite formation has been attracting increasing attention as a near mature technology to recover nutrients from anaerobic digestion. However, struvite feasibility is generally limited by the high cost of chemical reagents. Because the economic feas

Abstract:
In the present work Mg and MgAl thin films were fabricated using physical vapour deposition (PVD) technologies as non-traditional and new nanotechnology methods for designing high performance hydrogen storage materials. The physical vapour deposition technologies allow the formation of metastable metal, alloy and chemical compounds with strictly controlled composition, microstructure and stoichiometry at low temperatures. The synthesis of MgH2, MgAl and Mg(AlH4)2 films has been conducted in two steps: (i) fabrication of thin films employing magnetron sputtering in Ar gas, and (ii) hydrogenati

Abstract:
<p>Molten magnesium will oxidize uncontrollably in an atmosphere of air. To inhibit this, a protective gas is used to cover the melt. The gas most commonly used today is SF<sub>6</sub>. Fluorine is known to be the active component of the gas. There is a major problem with SF<sub>6</sub>, and that is that it has a strong Global Warming Potential (GWP). The GWP of SF<sub>6</sub> is 23 900 times that of CO<sub>2</sub>.</p><p>The aim of the present work is to understand the mechanism of the protection of molten magnesium. Hopefully, this allows us to find less problematic alternatives to the use o
