Summary: Metasurfaces have the ability to confine electromagnetic fields on large surfaces and zones, making them suitable for applications in biochemical sensing, photocatalysis, etc. They enhance the effects of SERS and SEIRA sensing by the presence of hotspots and confined optical modes within their structures, as well as by supporting resonances at frequencies of the excitation and emission processes. Additionally, Metasurfaces enhance the absorption capacity of solar light and generate more catalytic active sites for faster surface reactions.

Summary: In this study, we investigated chemical sensing using surface-enhanced Raman scattering with gold nanocolumn templates. The glancing angle deposition with magnetron sputtering technique was chosen for its low-cost production and ease of implementation. The fabricated gold nanocolumnar structures allowed for the production of a high density of strongly confined electric field spots. The vertical and tilted nanocolumnar templates showed promising results for the detection and adsorption of thiophenol molecules.

Summary: This study investigates the Fermi level shifts of gold nanospheres on zinc oxide (ZnO) film upon UV irradiation. The shifts are obtained by recording the extinction spectra of gold nanospheres and are attributed to the additional electrons stored in the nanospheres from ZnO film. The blueshift of plasmon resonance of the Au nanospheres indicates the transfer of electrons from ZnO film to Au nanospheres upon UV irradiation. The Fermi level shifts vary with UV irradiation time and can be estimated by a model based on the electronic structure of a semiconductor.

Summary: This study presents generic, analytical equations for the localized plasmons in a narrow gap between a metal/dielectric cylinder and a metal surface. The electric field distribution in the nanogap is obtained using the quasi-static approximation. The maximum electric field is achieved when the incident light is in resonance with the plasmon mode in the gap, and can be significantly enhanced. The analytical model results are in good agreement with a known theoretical model and experimental results of surface-enhanced Raman scattering (SERS). The narrow gap resonator appears to be a powerful and flexible tool for various spectroscopies such as SERS and infrared absorption.

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.
