Catalytic Mechanism Studies of Ortho–para H2 Conversion Over Iron Oxide Catalysts

EcoEnergy, EarlyView.
Herein, by estimating the reaction rate based on the per surface area of iron oxides, the Fe(III) exposed on surfaces exhibited a superior activity, and the intrinsic activity of iron oxides for ortho–para H2 conversion was found to follow the trend of α‐Fe2O3 ≈ γ‐Fe2O3 > Fe3O4.

Synthesis, Characterization, Magnetic Properties, and DFT Investigations of Heterobimetallic Nickel–Lanthanide LNiIILnIII (Ln = Ce, Gd, Tb, Dy) Complexes Supported by Schiff Base Ligands

European Journal of Inorganic Chemistry, EarlyView.
Four 3d4f heterobimetallic Schiff base complexes are designed from the ditopic N,N’‐bis(3‐methoxysalicylaldiimine)‐1,3‐propylene‐2‐ol ligand. Experimental dc magnetic measurements and density functional theory computational investigations converge to antiferromagnetic exchange interaction between Ni(II) and Ce(III) ions while ferromagnetic interaction ...

Hydroflux Synthesis and Crystal Structures of Na5[RE(OH)6][MO4] (RE = Y, Sc, Er–Lu; M = Cr, Mo, W) and Na8[Sc(OH)6]2[CrO4]

European Journal of Inorganic Chemistry, EarlyView.
Within a few hours, reactions in alkaline hydroflux yield large transparent single crystals of 16 new rare‐earth chromates, molybdates, and tungstates. Most of them crystallize in two only slightly different monoclinic structure types, which are related by a common supergroup.

Current Practices for Analyzing Soils and Sediments via Mössbauer Spectroscopy

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Environmental scientists are increasingly returning to Mössbauer spectroscopy (MBS) to reveal details about iron (Fe)‐bearing phases in soils and sediments. MBS is particularly powerful at distinguishing between Fe(II) and Fe(III) and, given appropriate background information, can offer exceptionally precise information on Fe speciation in ...
