Summary: The MO properties of bilayed and trilayered magneto-plasmonic crystals were analyzed, showing strong resonant bands and superior Faraday effects in structures with perforated holes.
The evolution of resonant bands is influenced by the size and period of holes, layer thickness, and incident light polarization, with optimized MPCs exhibiting significantly better Faraday rotation and transmittance compared to continuous films.

Summary: This article discusses the improvement of photocatalytic water pollution remediation through interfacial engineering using plasmonic metal-semiconductor heterostructures (PMSHs) and an optimized dissolved oxygen transporting channel. The synergetic effect of PMSHs and a superwetting reaction interface allows for efficient capture of photons and complete separation of electron-hole pairs. PMSHs based triphase systems show significantly higher efficiency compared to traditional solid-liquid systems and PMSHs based solid-liquid systems, with stability and wide applicability for organic dye degradation, making it a promising method for practical pollutants water treatment.

Summary: Implicit solvation is an effective coarse-grained approach in atomic-scale simulations, commonly used in modeling electrochemistry and electrocatalysis, but faces challenges such as describing the entire double layer forming at the solid-liquid interface within tractable supercell sizes in DFT. Additional experimental or high-level theoretical data is needed for further advancement of this methodology in the SLI context.

Summary: In this study, simple Ag@Pt bimetallic nanocubes were used to explore the mechanism of hot electrons from excitation and transmission within a plasmonic metal heterostructure and their contribution to the electrochemical hydrogen evolution reaction (HER). Experimental and theoretical results confirmed that the introduction of thin Pt shells resulted in hot electrons becoming the dominant plasmon decay pathway, and HER could be significantly enhanced through a cascaded manner. This work provides an important reference for the design and application of plasmonic metal heterostructure catalysts.

Summary: Poly(ethylene oxide) (PEO) based solid-state electrolytes show potential for practical all solid-state Li-metal batteries (ASSLMBs) due to their good chemical stability. However, the use of thin PEO presents a risk of short circuit in its semi-molten state, and PEO can be oxidatively decomposed by cathodes under high voltage, hindering the practical application of PEO-based ASSLMBs. In this study, the introduction of Nanodiamonds (NDs) into PEO electrolytes is found to greatly improve the electrochemical performance of PEO-based batteries by readjusting the Li+ and e(-) conductivity at the anode/cathode interface.

Summary: This study presents a novel biocatalytic cascade using Pickering emulsion droplets with two enzymes localized separately in the outer and inner interfacial layers. This approach allows the enzymes to be positioned in their preferred reaction microenvironments and in close proximity to each other on the nanoscale. The interfacial biocatalytic cascades exhibit remarkable catalytic efficiency in alkene epoxidation and thioether oxidation, with a catalytic efficiency 6.9-13.6 times higher than that of free enzymes in solution and their multi-enzymatic counterparts. The enhanced cascading efficiency is attributed to the remarkable interfacial effect of Pickering droplets.

Summary: A magneto-plasmonic structure Faraday rotator based on bismuth-iron garnet with opened metal microstructure is proposed, and its performance in Faraday rotation and transmittance in the mid-infrared wavelength band is investigated. The optimal performance is achieved in the double-opened toroidal magneto-plasmonic structure, which offers a wider spectral range and a larger Faraday rotation angle compared to other structures. By adjusting the thickness of the bismuth-iron garnet, more stable data can be obtained. The designed structures show greater extraordinary optical transmission effects compared to periodic arrays of plasmas.

Summary: A fundamental understanding of electrochemical processes in batteries at the atomic level is crucial for improving the performance of commercialized battery technologies and developing new cell chemistries. Transmission electron microscopy (TEM) techniques are useful for localized structural and chemical analysis, but the sensitivity of electrode materials and their interfaces to ambient conditions and high-energy electron beams necessitates cryogenic cooling during sample preparation, transfer, and imaging. In this perspective, the authors outline the major experimental workflows for cryogenic TEM analysis and provide comprehensive guidelines for studying battery-related materials and phenomena.

Summary: This study demonstrated the electrochemical sensing of putrescine and cadaverine using a liquid-liquid microinterface strategy, with improved sensitivity achieved by the microinterface structure and the addition of dibenzo-18-crown-6. The peak shaped voltammogram in the backward scan indicated linear diffusion of putrescine and cadaverine, and the presence of dibenzo-18-crown-6 enhanced the detection ability for both biogenic amines.

Summary: This paper presents a convenient technical scheme for enhancing the performance of atomic force microscopy (AFM) tips in tip-enhanced Raman spectroscopy (TERS) applications. The silver decoration on homemade tips is confined to the apex of commercial tips through an AFM-controlled electrochemical reaction. The efficiency of the metal coating is ensured by the reduction of Ag+ in a highly sealed environment. Key factors affecting the process include the use of silver nitrate solution, ambient relative humidity and temperature, electric potential bias, and tip-surface distance. The silver-coated tips are then tested for TERS measurement of carbon nanotubes (CNTs), resulting in simultaneous characterization of the CNTs' morphology and chemical properties. The Raman spectra show that our plasmonic tip exhibits a local field signal increase of approximately 30-fold, and the corresponding TERS image can resolve at the single-pixel level laterally.
