The produce of high-efficiency materials in hydrogen evolution technology is a priority. Recent development in graphene-based material shows that it can be a good candidate for this target. Accordingly, the MoCoFeS/reduced graphene oxide (rGO) catalyst was prepared by the hydrothermal method for hydrogen evolution reaction. The catalysts were characterized and the effect of rGO on the electrochemical properties of the catalyst was examined. Our results are encouraging that, the optimized catalyst (MoCoFeS/rG00.4) at -110 mV overpotential with a Tafel slope of 50.26 mV dec(-1) can be a novel candidate for an active non-precious metal hydrogen evolution reaction catalyst.

Summary: The influx of matter from impacting meteoroids and hydrothermal crater weathering plays an important role in modifying the rock and mineral inventory of young planets. These processes not only affect the geochemical environment of early planets like Mars, but also the prebiotic chemistry on early Earth. The study found that both plasma-initiated synthesis during impact and post-impact thermochemistry can produce nucleobases and amino acids, with the latter being essential in the formation of intermediate species.

Stefano Borocci, Armando Camerlingo, Felice Grandinetti, Maria Rutigliano, Nico Sanna

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.].

Investigation of Ce-based buffer layers on electrochemical performance of YSZ-based symmetric solid oxide fuel cells

Chanchan Wang, Quan Yang, Yanzhi Ding, Xiaoyong Lu, Dong Tian

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.
