Summary: The development of ultramicroelectrodes and nanoelectrodes has opened up new possibilities for investigating electron transfer phenomena, especially in the field of scanning electrochemical microscopy (SECM). In this study, a multi-channel nanoelectrode bundle was developed for simultaneous electroanalysis of multiple orthogonal redox reactions in one bath, greatly improving the time efficiency of SECM operations. The nanoelectrode bundle was also demonstrated to be a stand-alone microprobe for electroanalytical investigations in small volumes. This development is expected to benefit electrochemical analyses in various systems, particularly those involving SECM and fine spatial control.

Summary: This strategy demonstrates a controllable method to fabricate polymeric nanowires with high throughput and low cost using thermal nanoimprint lithography (NIL) technique and self-assembled anodic aluminum oxide (AAO) template. The length of polymeric nanowires can be adjusted by the duration of thermal NIL, and the fill mechanism of thermoplastic intermediate polymer stamp (IPS) into AAO nanopores is essential for the preparation of SERS-active substrates. The approach shows potential for expanding the use of thermal NIL technique and AAO template for fabricating various nanomaterials, especially flexible and transparent polymer-based nanomaterials.

Summary: Novel chitosan-based polymer inclusion membranes (PIMs) were synthesized for the removal of malachite green dye (MG) in this study. Both PIMs displayed good stability and achieved removal efficiencies of 96% and 98% at pH 4 and initial concentration of 50 mg/L, respectively. The average removal efficiency for different environmental samples (river water, seawater, and tap water) was around 90%. Therefore, the investigated PIMs can be considered as a potential suitable technique for the removal of dyes and other contaminants from aquatic matrices.

Summary: Research on double network (DN) hydrogels has gained attention due to their unique structural, physicochemical, and functional properties. DN hydrogels offer a broader range of functional attributes than single network (SN) hydrogels, which results in their diverse applications. While there is interest in developing biopolymer DN hydrogels for their environmental benefits, limited knowledge exists on their formation and application. This article reviews the principles, formation mechanisms, network structures, and functional attributes of DN hydrogels, as well as their potential applications in tissue engineering, biomedicines, and foods. Further research is needed to overcome the current limitations of DN hydrogels.

Summary: In this study, nano-particulate MoS2 was explored as a hydrogen evolution reaction (HER) catalyst. The onset potential at pH 2 was found to be -0.10 V (vs RHE), which was confirmed to be due to HER. XPS and XRD analysis were used to categorize the materials and confirm their chemical composition and crystal structure. The early onset of HER was postulated to be due to the presence of nanoplatelets.

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.
