Nanocubes and Cuboctahedra: Entropic Stabilization Versus Thermal Segregation in Rock Salt‐ and Spinel‐Type Multinary Oxides from Spray‐Flame Synthesis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Spray‐flame synthesis enables highly flexible and scalable production of multinary and high‐entropy oxide nanoparticles due to high synthesis temperatures with subsequent quenching. Temperature‐dependent in situ diffraction of as‐synthesized materials clearly reveals entropy stabilization in rock salt lattices, while spinels—featuring tetrahedral and ...

Interfacial Charge‐Transfer Enhancement via High‐Entropy Alloy Regulated MXene Heterostructures for Asymmetric Supercapacitor Applications

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A novel core‐shell HEA@MXene composite was synthesized to enhance supercapacitor electrochemistry. DFT simulations reveal the role of HEA doping in regulating the MXene interface. The HEA@MXene composite exhibits a high specific capacitance of 872 F g−1 at 1 A g−1 with remarkable stability in 1 M KOH.

Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

Anion Exchange Pathways in Half‐Heusler‐Type Holmium Hydride Oxide HoHO

European Journal of Inorganic Chemistry, EarlyView.
The oxidation of half‐Heusler‐type holmium hydride oxide HoHO in air is tracked by in situ neutron powder diffraction, revealing Ho2H0.50O2.75 as the holmium analogue of the Y2H0.50O2.75 intermediate in YHO. Despite nearly identical ionic radii and closely related intermediate structures, the holmium system shows a narrower stability range and faster ...
