Summary: Ag-Mn2O3 was evaluated as a new photosensing material for detecting UV-visible-NIR radiation, and its performance was compared to single-phase Mn2O3. The Ag-Mn2O3 prepared by coprecipitation method showed significantly higher electrical current variations than Mn2O3, which can be attributed to a decrease in bandgap energy, the formation of metal-semiconductor heterojunctions, as well as the lower work function and higher free electron concentration of silver.

Summary: In this study, new efficient luminescent silver cluster-based coordination polymers were designed for the detection of nitrobenzene (NB). These polymers, composed of Ag-10, Ag-12, and Ag-12 cluster cores connected by multidentate pyridine linkers, exhibit highly sensitive luminescence quenching effects to NB due to the pi-pi stacking interactions between the polymers and NB as well as the electron-withdrawing character of NB.

Summary: The complexes of He, Ne, Ar, Kr, and Xe with B3N3H6 were investigated using MP2, CCSD(T), and SAPT ab initio methods. The complexes can be described as mono-, di-, and tri-coordinated to the N atoms, with stability following the order N-mono < N-di < N-tri. The interactions are dominated by dispersion and the binding energies are within the range of 1 or 2 kcal mol(-1). The results were compared with a recent DFT study on larger BN sheets complexes [Phys. Chem. Chem. Phys. 24 (2022) 2554-2566.].

Summary: It has been found that the introduction of buffer layers improves the electrical performance of solid oxide fuel cells (SSOFCs). In this study, varying ratios of Gd-doped CeO2 were used as buffer layers in YSZ-based SSOFCs. The results demonstrate that the performance of SSOFCs is enhanced when a buffer layer is added, with the highest performance achieved using Ce0.8Gd0.2O2-delta (GDC20) as the buffer layer. This suggests that the use of GDC series buffer layers is an attractive strategy to optimize performance loss due to electrolyte-electrode interactions.

Summary: This study investigates the influence of aspect ratio and quantum confinement on the single-photon and two-photon absorption cross-section of perovskite CsPbI3 nanorods. Experimental data shows that CsPbI3 nanorods have an extremely high two-photon absorption cross-section, significantly surpassing organic chromophores and other CsPbBr3 nanocrystals. Moreover, adjusting the aspect ratio can significantly enhance the absorption ability. Additionally, the study also reveals a moderate quantum confinement effect on the single-photon and two-photon absorption cross-section of the nanorods.
