Structural and magnetic investigation of Fe-doped Mn3−xFexO4 (x ≤ 0.1) [PDF]

AIP Advances
In this study, structural and magnetic properties of Fe ion-containing manganese ferrites Mn3−xFexO4 (x ≤ 0.1) have been investigated by using x-ray diffraction, superconducting quantum interference device magnetometer, and Mössbauer spectroscopy.

Determination and Recovery of Spin‐States for a High‐Spin and a Spin‐Crossover Complex by Means of X‐Ray Wavefunction Refinement

Chemistry – A European Journal, EarlyView.
The determination of spin‐states by methods like Hirshfeld atom refinement is a promising development in the field of quantum crystallography. To this end, we present x‐ray wavefunction refinement as a next step in this process, identifying the spin and translating it into a physical wavefunction.

Impact of A‐Site Sr Substitution in LaFeO3 on Syngas Selectivity During Chemical Looping Dry Reforming of Methane (CL‐DRM)

Chemistry – A European Journal, EarlyView.
Sr doping regulates oxygen exchange and methane activation in LaFeO3, suppressing nonselective CH4 cracking and coke formation during CL‐DRM. La0.7Sr0.3FeO3 provides the optimal balance, delivering ∼40% CH4 conversion, an H2/CO ratio of 2, and >95% carbon balance.

Fe–Ca‐Catalyzed Conversion of Cellulose Into Highly Ordered Graphitic Carbon Revealed by Solid‐State 13C NMR and Mössbauer Spectroscopy

Chemistry – A European Journal, EarlyView.
New insights into the mechanism of the structural transformation of cellulose into highly ordered graphitic carbon using an Fe–Ca bimetallic catalyst were obtained through complementary spectroscopic techniques, including Raman, solid‐state NMR, and Mössbauer.

A Self‐Enhanced Tandem Catalytic System for Olefin‐to‐Diol Conversion Powered by Single‐Atom Fe Catalysts With In Situ Generated Acid

EcoEnergy, EarlyView.
A single‐atom iron catalyst with well‐defined Fe–N4 sites enables a tandem epoxidation‐hydrolysis process for converting terminal olefins to 1,2‐diols. The in situ‐generated isobutyric acid drives the hydrolysis step, affording broad substrate scope and excellent recyclability.
