Summary: A plasma-assisted catalyst modified with biochar was found to significantly enhance the photoactivity of TiO2 for formaldehyde abatement. The addition of 5% biochar to the catalyst (C/TiO2) achieved the highest removal efficiency by increasing meso/microporous structures, decreasing the bandgap, and diminishing the recombination rate of electron-hole pairs. This new catalyst has promising applications for the degradation of volatile organic compounds.

Summary: In this study, zinc-chromium mixed metal oxide/fly ash (ZnCr-MMO/FA) composites were prepared using fly ash from Chinese coal mining power plants, showing improved photocatalytic performance for pollutant degradation. The composites exhibited higher degradation activity for ciprofloxacin compared to the pure ZnCr-MMO, attributed to the good arrangement of particles and reduced recombination of charge carriers. Therefore, the proposed composites can be used as effective photocatalysts for wastewater treatment, including the decomposition of organic pollutants.

Summary: For the first time, titania-based photocatalysts with different crystalline compositions and morphology were modified and tested for antimicrobial activity. The antimicrobial inactivation mechanism was found to follow two different pathways, depending on the conditions. The improved photocatalytic activity of the modified samples was attributed to the hindrance of charge carriers' recombination by phosphate anions in the modification.

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.
