Summary: Exploring transition metal-based electrocatalysts with excellent performance in alkaline overall water splitting is important but challenging. In this study, a bimetallic Ni-Co selenide heterostructure aerogel (NiSe2-CoSe2) was designed and prepared for efficient overall water splitting. The optimized sample showed extremely low overpotentials for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in 1 M KOH electrolyte. Assembled as an electrolyzer, NiSe2-CoSe2 achieved high current density at low cell voltage, comparable to commercial noble-metal catalysts. The exceptional performance was attributed to the unique porous morphology and bimetallic selenide heterostructure. This work provides an anticipated perspective for transition metal selenide bifunctional electrocatalysts.

Summary: This study focuses on the production and investigation of NiFe2O4 spinel ferrite nanoparticles doped with different masses of Se. The results show that the chemical content of Se has an impact on the crystal structure, microstructure, and magnetic properties. Superparamagnetic and ferrimagnetic states are observed in a wide magnetic field range. The magnetic characteristics do not change significantly when Se-substitution is less than 2.0%. However, a nonlinear dependence of magnetic parameters is observed for samples with Se-substitution greater than or equal to 2.0%. The undoped sample and NiFe2O4+x%Se exhibit soft magnetic behavior.

Summary: This review introduces X-ray detectors using various halide perovskite materials and discusses their performance. Single-crystal perovskite as an active material exhibits excellent performance under X-ray illumination, while inorganic perovskite shows good environmental stability and high X-ray sensitivity. Double perovskite with the introduction of high-atomic-numbered elements demonstrates better attenuation of X-rays, and lead-free perovskite exhibits potential application in X-ray detectors due to its high X-ray attenuation capability. The up-scaling process technology for fabricating large-area and thick perovskite films for X-ray detectors is also introduced.
