Summary: By using advanced transmission electron microscope techniques, two alternative particle attachment growth pathways dominating the growth of Au@Ag core-shell nanocuboids are directly observed. One pathway involves the in situ reduction of AgCl nanoparticles attached to Au nanorods and the subsequent epitaxial growth of the Ag shell. The other pathway involves the adherence of Ag-AgCl Janus nanoparticles to Au nanorods with random orientations, followed by nanoparticle redispersion and the resulting formation of epitaxial Ag shells on the Au nanorods. The particle-mediated growth of Ag shells is accompanied by the redispersion of surface atoms, tending to form a uniform structure, providing a new mechanistic understanding of core-shell nanostructure synthesis.

Summary: A SERS-based immunosensor was developed for the detection of Zearalenone (ZEN) in corn. The immunosensor utilized gold nanostars (AuNSs) modified with ZEN monoclonal antibodies as the capture probe, and core-shell structures loaded with Raman reporter molecules as the Raman signal probes. The method showed a detection range of 5 - 400 μg/kg for ZEN in corn samples, with a LOD of 3 μg/kg, meeting the requirement of maximum residual level. The results were consistent with the HPLC-FLD method.

Summary: Plasmonic photocatalysis is a promising strategy for inducing chemical transformations under visible-light irradiation. However, efficient utilization of hot electrons on monometallic nanoparticles remains challenging. In this study, Au-core-Ag-shell bimetallic nanoparticles showed higher catalytic activity than pure Au and Ag nanoparticles for the reduction of 4-nitrothiophenol to 4,4'-dimercaptoazobenzene. The catalytic activity was dependent on the thickness of the Ag shell and could be explained by hot-electron-hole separation at the bimetallic interface. This work provides new opportunities for enhancing the efficient utilization of hot electrons in plasmonic photocatalysis reactions.

Summary: The distance dependence of triplet-triplet annihilation upconversion (TTA-UC) systems remains unexplored. This study investigated the influence of the spatial distance between Ag nanoprisms (AgPRs) and TTA-UC thin films on UC emission. The optimal distance was found to be significantly longer than typical metal-enhanced fluorescence systems. The UC emission enhancement was affected by factors such as PdOEP photoexcitation rate, triplet-triplet energy transfer efficiency, DPA lifetime, and fluorescence efficiency.

Summary: In this study, a low-cost Cu-based nanostructure with localized surface plasmon (LSP) resonance was developed as a photothermal therapy agent in the second biological transparency window. The strong LSP resonance and superior photothermal conversion ability were achieved by generating the dipolar bonding mode between the nanoshell dipole and the nanohole dipole. The cytotoxicity of Cu-based nanostructures was effectively suppressed by surface protection, making them excellent photothermal therapy agents.

Summary: The design of a solid electrolyte interphase (SEI) plays a crucial role in improving the electrochemical performance of anode materials. In this study, lithium difluoro(oxalate)borate (LiDFOB) is used as an electrolyte additive to form a protective SEI film on Li3VO4 (LVO) anodes. The addition of LiDFOB results in a dense, uniform, stable, and LiF-richer SEI, which enhances the Li-ion storage kinetics. The generated SEI also prevents further decomposition of the electrolyte and maintains the morphology of LVO anodes during charge/discharge processes. This work demonstrates the effectiveness of LiDFOB as a multi-functional additive for LiPF6 electrolytes and provides insights into SEI construction for high-performance LVO anodes.

Summary: In this study, we used density functional theory (DFT) calculations to investigate the interaction between model graphene oxide (GO) nanostructures and chlorine monoxide ClO. We aimed to understand the role of this highly oxidizing species in breaking C-C bonds and forming significant holes on GO sheets. Our results showed that C-C bonds in a single graphene oxide sheet can be broken through a simple mechanism involving the dissociation of two chemically attached ClO molecules. The formation of carbonyl groups and holes on the GO surface was also observed. This study provides important insights into the degradation of carbon nanotubes and the stability of GO during the myeloperoxidase (MPO) catalytic cycle.

Summary: In this study, the X-ray stability of five different lead halide perovskite compositions (MAPbI3, MAPbCl3, MAPbBr3, FAPbBr3, CsPbBr3) was investigated using photoelectron spectroscopy. Different degradation mechanisms and resistance to X-ray were observed depending on the crystal composition. Overall, perovskite compositions based on the MA+ cation were found to be less stable than those based on FA+ or Cs+. Metallic lead formation was most easily observed in the chloride perovskite, followed by bromide, and very little in MAPbI3. Multiple degradation processes were identified for the bromide compositions, including ion migration, formation of volatile and solid products, as well as metallic lead. CsBr was formed as a solid degradation product on the surface of CsPbBr3.

Increasing the manganese content leads to a decrease in stability. The behavior of iron and manganese in the oxide shows distinct differences, which can be attributed to the difference in the enthalpy of oxidation reactions.
