Summary: This study detected the hot electron transition of noble materials to catalysis accelerated by localized surface plasmon resonances (LSPRs) using in situ irradiated X-ray photoelectron spectroscopy (ISI-XPS). A core-shell structure of Ag Nanowire (AgNW) @ WS2 was synthesized, showing enhanced photocatalytic properties with different effects controlled by changing the shell thickness. The hot electrons arising from the LSPRs effect enhanced the photocatalytic effect of WS2 shell, leading to accelerated catalysis.

Summary: In this study, the progress of nanoengineering on noble metals and the extreme nonlinear optics within nanometric volumes are explored. Plasmonic nanostructures are found to offer a unique route for enhancing high-order harmonic generation and other nonlinear optical progress. The researchers demonstrated a strong third harmonic emission in zinc oxide microbelts through a strong localization of electromagnetic field caused by localized surface plasmon resonances. The intensity of third-harmonic generation was enhanced significantly in a composite of microbelts and Au nanoparticles, compared to the bare microbelts. Additionally, the polarization characteristics of the third-harmonic generation in the same system were improved significantly.

Summary: A new-type TMD-based photodetector embedded with nanoslits is proposed to enhance light trapping. Strong anisotropic optical responses are discovered due to the intrinsic in-plane anisotropy and nanoslit-enhanced anisotropy. By controlling the angle between the nanoslit orientation and the polarization direction, polarization-sensitive photodetectors with anisotropy ratios from 5.9 to 12.6 can be achieved.

Summary: Enhanced light-matter interaction is crucial for improving the performance of nanophotonic devices. This study proposes a dielectric metasurface that can enhance the light-matter interactions in graphene. A symmetry-protected optical bound state in the continuum (BIC) is observed in this metasurface, which can transform into a high-quality quasi-BIC with the breaking of in-plane symmetry. The introduction of graphene monolayer enhances absorption, and a tunable absorber can be achieved by optimizing the system parameters.

Summary: In this study, surface-enhanced infrared absorption spectroscopy was used to monitor the denaturation process of a surface-bound protein A monolayer. By comparing the reflectance spectra of different states, changes in the protein's vibration modes can be determined. It was found that hydrogen bond breaking during denaturation caused red-shifts in the principal vibration modes, creating barriers for refolding.

Summary: Next generation High Energy Physics (HEP) accelerators require new devices and technologies capable of operating in extreme environments with ultra-high radiation doses. A Lab-On-Fiber (LOF) probe based on a metallo-dielectric nanostructured grating has been developed for real-time dose monitoring. Experimental results show that the LOF resonance wavelength and depth are dependent on the absorbed dose, and the main effect of radiation is the reduction of the PMMA thickness, which affects the resonance behavior.
