Summary: In this study, a water transfer method was developed to fabricate thin-film patterns on 3D curvilinear surfaces. By suspending crystalline silver nanoplates in ethanol with a surfactant and spreading the suspension over the water surface, a self-assembled thin film was generated. The thin film could be effectively transferred to object surfaces with nanometer thickness and exhibited superior conductivity without thermal sintering.

Summary: Tin-containing layers with different degrees of oxidation are uniformly distributed along the length of silicon nanowires formed by a top-down method. The electronic and atomic structure of the obtained layers is investigated using nondestructive X-ray absorption spectroscopy. The distribution effect of tin-containing phases in the nanostructured silicon matrix is demonstrated, and the amount and distribution of tin-containing phases can be varied and controlled by adjusting the geometric parameters.

Summary: Four X-shaped quinoxaline-based organic dyes, PQx (1), TQx, (2), PQxD (3), and TQxD (4), are developed as p-type self-assemble monolayer (SAM) for tin perovskite solar cells (TPSC). The thermal, optical, and electrochemical properties of these SAMs are thoroughly investigated. Tin perovskite layers are successfully deposited on these SAM surfaces using a two-step approach, and the achieved device performance follows the order of TQxD (8.3%) > TQx (8.0%) > PQxD (7.1%) > PQx (6.1%). Among them, TQxD (4), with a thiophene pi-extended conjugation unit in the SAM structure, exhibits the highest hole extraction rates, greatest hole mobilities, and slowest charge recombination, leading to the best reported efficiency of 8.3% for SAM-based TPSC. Moreover, all devices except PQx show good enduring stability, retaining approximately 90% of their original values after 1600 hours of shelf storage.

Summary: An efficient protection strategy has been developed to enhance the adhesion force and stability of silver nanowire-based transparent electrodes. Chitin nanofibers (CNFs) and alkali lignin (AL) are assembled on the surface of AgNW TEs through layer-by-layer (LBL) assembly. The resulting CNF/AL bilayer-coated TEs show improved adhesion force and durability without compromising their electrical conductivity and transmittance.

Summary: A large-scale, simple, multi-microdomain, and non-contact photoalignment technology is demonstrated to align colloidal silver nanowires (AgNWs) in a liquid crystal (LC) with high two-dimensional order parameter. The AgNWs are precisely self-assembled via photomasks with twisted nematic and planar alignment models in microdomain regions. The orientation of AgNWs is tuned with an electric field, enabling three-dimensional tunable orientation combined with photoalignment. This approach provides a new way to assemble large colloidal nanomaterials and fabricate functional E-O devices.

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.
