Spinel oxides are an ideal setting to explore the interplay between configurational entropy,
site selectivity, and magnetism in high-entropy oxides (HEOs). In this work, we characterize …

Layered honeycomb cobaltates are predicted as promising for realizing the Kitaev quantum
spin liquid, a many-body quantum entangled ground state characterized by fractional …

Environmentally friendly catalytic composites based on cobalt and a natural clay as
catalytically active phase and support, respectively, are herein reported for the valorization …

Quantitative assessment of the charge transfer phenomena in cobalt oxides and cobalt
complexes is essential for the design of advanced catalytic materials. We propose a method …

We have performed cobalt L-edge X-ray absorption spectroscopy (XAS) on important
materials for photoactive catalysis, namely nanoscale cobalt polyoxometalates (Co POM) …

Theoretical predictions show that depending on the populations of the Fe 3d xy, 3d xz, and
3d yz orbitals two possible quintet states can exist for the high-spin state of the …

This paper represents a call to the broader XAS community to more closely assess dose, as
well as the other experimental factors (detection method, temperature, pressure and sample …

The charge and spin-state evolution of manganese and cobalt in the LaMn1–x Co x O3 (x=
0.00, 0.25, 0.50, 0.75, and 1.00) perovskite nanoparticles have been studied with soft X-ray …

The electronic structure of a material plays an important role in its functionality for different
applications which can be probed using synchrotron-based spectroscopy techniques. Here …

CoO has an odd number of electrons in its unit cell, and therefore is expected to be metallic.
Yet, CoO is strongly insulating owing to significant electronic correlations, thus classifying it …
