Electronic structure and oxidation states in high-pressure synthesized isostructural CeCN5_5 and TbCN5_5

This study employs DFT+U and DFT+DMFT calculations to reveal that despite being isostructural high-pressure synthesized compounds, CeCN5_5 and TbCN5_5 exhibit distinct electronic properties—CeCN5_5 being an insulator with Ce in a 4+ oxidation state and TbCN5_5 being a metal with Tb in a 3+ oxidation state—demonstrating how the polymeric C-N network accommodates different lanthanide oxidation states and modulates electronic behavior.

Structural, optical and magnetic properties of nanostructured Cr-substituted Ni-Zn spinel ferrites synthesized by a microwave combustion method

Nanoparticles of Cr-substituted Ni-Zn spinel ferrites synthesized via microwave combustion exhibit a single-phase spinel structure with Cr³⁺ ions preferentially occupying B-sites, resulting in decreased lattice parameters and band gap energy, enhanced saturation magnetization at low doping levels, and improved photocatalytic degradation of methyl orange dye.
