Summary: In this study, ZnO, Er:ZnO, hybrid Ag/ZnO, and Ag/Er:ZnO colloidal nanoparticles were synthesized using pulsed laser ablation. Characterization techniques including XRD, TEM, UV-visible absorption, and photoluminescence spectroscopy were employed. The hybrid Ag/Er:ZnO colloidal nanoparticles exhibited a significantly enhanced photocatalytic activity, with a degradation efficiency of 96.4% for Rhodamine 6G dye under UV irradiation for 45 minutes, compared to 79.7% for pristine ZnO nanoparticles. These results highlight the potential of pulsed laser ablation in pure water as a fast and environmentally friendly technique for producing efficient nanoparticle photocatalysts.

Summary: Introducing organic compounds to electrode materials as a replacement for expensive inorganic-based materials is an effective and eco-friendly cost reduction strategy. In this study, amino acid-substituted derivatives of perylene diimide (PDI_AAs) demonstrated redox-active characteristics and were utilized as cathode materials in lithium-ion batteries (LIBs). Among the synthesized PDI_AAs, L-alanine-substituted PDI (PDI_A) exhibited the highest cycling performance, maintaining a capacity of 86 mAhg(-1) with 95% retention after 150 cycles at 50 mAg(-1). Furthermore, PDI_A displayed a long-term cycling performance with a capacity of 47 mAhg(-1) (98% retention) over 5000 cycles at a high current density of 500 mAg(-1). Ex situ attenuated total reflection Fourier-transform infrared spectroscopy (ATR FT-IR) analysis revealed the charge-discharge mechanism of PDI_A electrodes at different charging states.

Summary: In this study, ternary heteronanocrystals composed of two different plasmonic metal nanocrystals (hexoctahedral Au and spherical Ag nanocrystals) and a semiconductor (Cu2O) were synthesized. These ternary heteronanocrystals exhibited enhanced photocatalytic H-2 evolution performance over a wide range of visible-light wavelengths compared to binary and monomeric counterparts. The improved photocatalytic function can be attributed to the combination of the distinct plasmonic properties of the two different metal nanocrystals with the semiconductor, enabling the promotion of both plasmon-induced charge and energy transfer processes.

Summary: Conjugating plasmonic metals with catalytically active materials with controlled configurations can harness their light energy harvesting ability in catalysis. Herein, a well-defined core-shell nanostructure composed of an octahedral Au nanocrystal core and a PdPt alloy shell is presented as a bifunctional energy conversion platform for plasmon-enhanced electrocatalysis. The prepared Au@PdPt core-shell nanostructures exhibited significant enhancements in electrocatalytic activity for methanol oxidation and oxygen reduction reactions under visible-light irradiation. Our experimental and computational studies revealed that the electronic hybridization of Pd and Pt allows the alloy material to have a large imaginary dielectric function, which can efficiently induce the shell-biased distribution of plasmon energy upon illumination and, hence, its relaxation at the catalytically active region to promote electrocatalysis.

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.

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.
