25Mg and 29Si NMR has also been used to study the thermal decomposition reactions of the related layer-lattice mineral talc, Mg6SigO20(OH)4, which was shown to form orthoenstatite, MgSiO3 by a simple reaction in which the Mg remains in octahedral coordination throughout (MacKenzie and Mein...

Redox reaction refers to a type of chemical reaction identified by the change in the oxidation states of the involved reactants. It is a short term for oxidation-reduction reaction, which are processes occurring simultaneously during the said reaction. These two processes al...
In the case of an adverse reaction, a second surgery to remove the implants may be necessary. Conversely, the higher elastic modulus8 of implanted biomaterials compared to human bone results in a stress shielding effect. Magnesium and its alloys have a considerable potential for biological ...
N2 - Initial subduction-related boninitic magmatism occurred between 48 and 44 Ma in the Izu-Bonin-Mariana (IBM) arc. High-Mg adakites and low-Ca boninites have been dredged from the Bonin Ridge fore-arc seamount. Whole-rock 40Ar/39Ar ages suggest that the boninite (44·0±1·4Ma) and...
Once MgH2 is formed, the reversible reaction between magnesium and hydrogen can be described by the following equation [23]:(1.1)MgH2(s)↔Mg(s)+H2(g),for this reaction the measured changes of enthalpy (ΔH) and entropy (ΔS) are 74.1 ± 0.4 kJ۰mol−1 H2 and 133.4 ± 0.7 J...

MgMnB2O5, Mg2/3Mn4/3B2O5, and Mg4/3Mn2/3B2O5 pyroborates have been prepared via a ceramic method. When charging MgMnB2O5 vs Li, all of the Mg2+ can be removed, and with subsequent cycles, 1.4 Li ions, corresponding to a capacity of 250 mAhg–1, can be reversibly int...
The reversible reaction equation for Li-Mg-N-H hydrogen storage materials is shown in Equation 1–1:(1-1)2LiNH2 + MgH2→ Li2MgN2H2 + 2H2 ↔ Mg(NH2)2 + 2LiH However, the activation energy of the Li-Mg-N-H system is generally higher than 100 kJ/mol [23], which is a ...
The proposed Mg-storage mechanism, including phase separation and transition reaction, is evaluated using advanced atomic scale scanning transmission electron microscopy techniques. This unusual Mg storage mechanism has rarely been reported for ion insertion-type electrode materials for rechargeable batteries....
