Summary: We predict and realize a new magnetic and semiconducting material, MnSnN2, through combinatorial sputtering of thin films. MnSnN2 exhibits a wide composition tolerance, with a single-phase region of 20% < Mn/(Mn + Sn) < 65%. The material shows a wurtzite-like crystal structure with cation disorder and has an optical absorption onset of 1 eV, consistent with the computationally predicted 1.2 eV bandgap. Resistivity and Hall effect measurements confirm the semiconducting nature of MnSnN2 and reveal complex charge transport mechanisms. Magnetic susceptibility measurements show a low-temperature magnetic ordering transition and strong antiferromagnetic correlations in MnSnN2, contrasting with previous studies on cation-ordered MnSiN2 and MnGeN2.

Summary: Mixed transition metal oxides are promising electrode materials for electrochemical energy storage and conversion. The synthesis of these materials with tailored composition, crystal structure, and morphology is crucial for optimizing their properties. This study reports on the room-temperature electrodeposition of a ternary oxide, ZnMnO3, using earth-abundant metals. The epitaxial growth of ZnMnO3 on ZnO nanowires results in a 2-dimensional morphology and shows promise for the direct growth of other mixed transition metal oxides on conductive substrates.

Summary: This study compared two methods, adsorption and in situ incorporation, for preparing hybrid polyphenol/hydroxyapatite nanoparticles. The results showed that adsorption of polyphenols on pre-formed nanoparticles did not change their properties, while in situ incorporation inhibited hydroxyapatite formation but resulted in higher loadings. Most hybrid particles exhibited a burst effect followed by slow release over time.

Summary: A series of beta-disubstituted meso-tetraphenylporphyrins and their metal complexes were synthesized and characterized. The phenylethynyl-substituted porphyrin exhibited a remarkable red shift in absorption compared to the methyl- and phenyl-disubstituted porphyrins, due to the inductive and resonance effect of the substituent groups. Single-crystal X-ray structure analysis revealed different conformations of the porphyrin core for methyl-substituted and phenylethynyl-substituted porphyrins.

Summary: Electrocatalysis and electrosynthesis are promising technologies for utilizing green renewable energy by converting and storing electrical energy in chemical forms. Most studies focus on developing advanced electrodes or active molecules to improve performance. However, the intrinsic characteristics of the electrodes limit direct acquisition and electron transfer. The introduction of redox mediators as intermediate electron carriers or reservoirs, without changing the final products, provides a unique approach to accelerate the electrochemical performance of these energy conversions. This review provides an overview of recent developments in electrocatalysis and electrosynthesis using redox mediators and a comprehensive discussion on the principles and construction of these systems.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
