Summary: Volatile organic compounds (VOCs) and hydrogen sulfide (H2S) are typical toxic gases that pose a threat to the environment and human health. The development of advanced sensing materials for gas sensors is crucial in order to meet the growing demand for real-time detection of VOCs and H2S gases to protect human health and air quality. In this study, bimetallic spinel ferrites with different metal ions were designed and evaluated for their crystal structures, electrical properties, and gas sensing capabilities. The results demonstrate that the NiFe2O4 and CuFe2O4 nanocubes with inverse spinel structure exhibit high response and selectivity towards acetone and H2S, respectively, with low detection limits below the threshold values set by ACGIH. This finding opens up new possibilities for the design of high-performance chemical sensors with potential practical applications.

Summary: In this study, copper-modified zirconium-based MOF-808 was presented as a colorimetric sensor material for visible, reversible, and sensitive H2S detection. The incorporation of copper cations in the +II oxidation state at the inorganic building units (IBUs) of the MOF-808 enabled interactions with H2S. The activated copper-doped MOF-808 powder exhibited significant and rapid color change in the presence of H2S, which could be detected by UV-vis spectroscopy. The detection process was reversible by heating the material, and it showed promising potential for selective sensing applications.

Summary: A novel phosphonate/phosphine oxide dyad molecular additive (PE-TPPO) is reported to enhance the device efficiency of metal-halide perovskite LEDs. The additive possesses unique dual roles of defect passivation and carrier radiative recombination enhancement. By modifying the defects and increasing local carrier concentration, this additive significantly improves the photoluminescence intensity and homogeneity of the perovskite film. The resulting green PeLEDs exhibit state-of-the-art efficiencies in terms of external quantum efficiency, current efficiency, and power efficiency.

Summary: The postannealing process is crucial for promoting the composition transfer of quantum wells in quasi-2D perovskites, with extended annealing time leading to a decrease in EQE but an improvement in working stability. Introducing TPTA to passivate emitting-region defects effectively eliminates the annealing-time dependence of EQE, resulting in simultaneous enhancement of efficiency and stability.
