Furthermore, ICP-OES results show that the molar ratio of Fe:Zn:Co:Ni:Cu is approximately 11:1:1:1:1, which is the same as the reactants mole ratio. (Table S2). The X-ray photoelectron spectroscopy (XPS) is employed to characterize the surface chemical compositions and element valence...
The partial molar volumes V 2 o and partial molar adiabatic compressibilities K s o were calculated. For the complex ions, [M(bpy) 3 ] 2+ and [M(phen) 3 ] 2+ , electrostatic interactions with the solvent are not nearly as important as effects due to the hydrophobic ligands bpy and...
[76] in their synthesis of Fe-ludwigite with a Fe molar fraction of 25% (i.e., f = 25%). Marincea [56] obtained temperatures around 600–650 ◦C for ludwigite formation in the Ocna de Fier deposit, Romania. Later, Bloise and Barrese [77] reported equivalent temperatures experi- ...
Materials and Sample Preparation The geopolymer matrix was prepared mixing metakaolin grade M1200S purchased from Imerys (ssa = 25 m2 g−1, d50 = 1.5 µm) with a solution of potassium di-silicate used as alkali activator, having a molar ratio of SiO2:K2O = 2 and H2O:K2O = 13.5. ...

The molar ratio of Fe to Zn was found to greatly affect the selective hydrogenation catalytic activity of ZnO-Fe2O3 mixed oxide supported gold nanocatalysts. Among these supported gold nanocatalysts in this work, Au/Zn0.7Fe0.3Ox (Au loading of 1.74 wt %) exhibited the highest conversion of ...
The molar ratio of the amino group in the component A to the epoxy group in the component B is selected to be 1/(1.6-2.6), preferably 1/(1.8-2.4).SAITO YASUHISA斉藤 康久TAKAGISHI TOSHIO高岸 壽男WATANABE KATSUYA渡辺 勝也KAMIO KUNIMASA...
