MgCl2/NaCl/KCl salt appeared as a high-potential heat transfer fluid for concentrated solar application, offering wide operating range and low cost. Nevertheless, MgCl2 hydrates atmosphere relative humidity are the limiting factors real scale CSP plant, leading to severe corrosion. Thus, Inconel 617 was tested at 700ºC up 24 h in air simulate punctual failure inertization system of plant. XRD S...

Cardiotoxin, protamine and polylysine are potent inhibitors of various cholinesterases. CaCl2 and MgCl2 overcome the inhibition. The order of addition of the inhibitor and the protecting agent (MgCl2) influences the final degree of the inhibition observed. These findings suggest that cardiotoxin, protamine and polylysine inhibit cholinesterases by the ionic binding of their basic groups with th...

Magnesium oxychloride cement (MOC) foam concrete (MOCFC) is an air-hardening cementing material formed by mixing magnesium chloride solution (MgCl2) and light-burned magnesia (i.e., active MgO). In application, adding caustic dolomite powder into magnesite can reduce the MOCFC production cost. The brine content of MOC changes with incorporation powder. This study investigated relationship betwe...

Summary Artificial N2 fixation is one of the most important industrial processes for human beings. However, current Haber-Bosch process based on fossil fuel suffers from unsustainability and a low to NH3 conversion. Here, we report magnesium chloride cycle synthesis H2O at atmospheric pressure. In this cycle, reacts with Mg form Mg3N2. Cl2 are produced by electrolysis molten MgCl2. NH4Cl used h...

Oxide ceramics could be attractive high-temperature construction materials for critical structural parts in molten salt thermal energy storage systems due to their excellent corrosion resistance and good mechanical properties. The 3D-printing technology allows the production of ceramic components with highly complex geometries, therefore extends applications. In this work, 3D-printed ZrO2 Al2O3...

Ni-catalyzed carboxylation of the C(sp(3))-Cl bond with CO2 in the presence of MgCl2 was theoretically investigated. MgCl2 plays three crucial roles in stabilization of a Ni(I)-CO2 adduct and acceleration of the CO2 insertion as a non-innocent additive and the one-electron reduction process as one kind of reagent.

Magnesium is an element essential for life and is found ubiquitously in all organisms. The different cations play important roles as enzymatic co-factors, as signaling molecules, and in stabilizing cellular components. It is not surprising that magnesium salts in microbiological experiments are typically associated with positive effects. In this study with Listeria monocytogenes as a model orga...
