Summary: We propose and demonstrate sandwich plasmonic nanocavities as a surface-selection ruler to illustrate molecular orientations using surface-enhanced Raman spectroscopy. The field vector in the nanocavity presents a transverse spinning feature under specific excitations, allowing the selective amplification of Raman modes of target molecules.

Summary: We experimentally demonstrate that nanoscale control of plasmonic field enhancement can be achieved by changing the polarization state of light. This is due to the mode-mixing property of circularly polarized illumination, which simultaneously excites multiple plasmon modes of the nanostructures. Trajectory calculations of the photoemitted electrons prove that the kinetic energy scaling law remains the same regardless of the polarization state.

Summary: Copper(I) thiocyanate (CuSCN) is a robust hole-transport material for perovskite solar cells, but the low crystallization of CuSCN limits its power conversion efficiency. This study focused on the humidity conditions during the aging process of CuSCN-based PSCs and found that aging in humid air with 70% relative humidity resulted in better performance (efficiency; 10.6%) compared to lower humidity (5.9%) due to improved crystallinity of CuSCN layers. These findings provide insights into improving the fabrication process of CuSCN-based PSCs for higher stability and efficiency.

Summary: Water evaporation-induced electricity generation is an emerging technology that can harvest electricity directly from natural water evaporation process. However, the low power density and conversion efficiency have hindered its practical applications, mainly due to weak water-solid interaction between evaporation-induced water flow and nanostructured materials. In this study, we propose a regulatory approach by introducing Ti vacancies at the atomic scale in two-dimensional nanostructures to enhance water-solid interaction for efficient electricity generation.

Summary: The structures, stability, and electronic states of 2D ruthenate were investigated by thermal and chemical methods. Contrary to previous reports, exfoliation of a oblique 1T phase precursor led to nanosheets with the same phase. Co doping resulted in nanosheets with metastable rectangular and thermally stable hexagonal 1T phases. Co doping suppressed the redox and catalytic activities under acidic conditions, but activated the Co2+/3+ redox pair and produced conductive nanosheets with high electrochemical capacitance in alkaline conditions.

Summary: Zinc-based aqueous energy storage technology has attracted widespread interest due to its low cost, high energy density, high safety, and environmentally friendly manufacturing process. However, the generation of hydrogen gas and zinc dendrite formation have impeded its progress. This study introduces a promising interfacial engineering strategy by depositing molecularly thin Ti0.87O2 nanosheets on a zinc electrode surface, which effectively suppresses hydrogen gas evolution and reduces the nucleation potential of zinc. The improved electrode performance leads to a drastically increased cycle life of over 1400 hours at 1 mA cm(-2)/1 mAh cm(-2), enabling practical applications of zinc metal electrodes and showing potential for other metal batteries.

Summary: The effectiveness of multiwalled carbon nanotubes (MWCNTs) in enhancing the suitability of MXenes for energy-related applications is explored. The control over the structure of MXene-based macrostructures by individually dispersed MWCNTs is investigated. The results show that the composition and surface structure of MXene films are significantly altered by the presence of MWCNTs. The stacking order of MXenes is preserved up to 30 wt% MWCNTs, but disrupted at 40 wt%. The membranes with MWCNTs exhibit improved Li-ion transport mechanisms and properties. A high rating of 8 is given for the importance of this research.
