Summary: Researchers have successfully achieved reactive oxygen species (ROS) augmentation in mild photothermal therapy (mPTT) by fabricating Au@Pd bimetallic nanozyme. This nanozyme exhibits multienzymatic activities for photothermal conversion and induces ROS generation, which helps to suppress the heat-defense response of tumor cells and improves therapeutic efficacy.

Summary: In this study, a novel sulfidated nZVI core-shell particles (FeS/Fe (0)) were successfully fabricated via a modified post sulfidation approach, showing better performance compared to traditional nano zero-valent iron in removing Cr(VI) from water. The sulfidated iron shell with higher electronegativity can accelerate iron corrosion, facilitate electron transfer, and improve the removal efficiency of Cr(VI).

Summary: This study demonstrates an efficient strategy of fabricating superior photocatalytic systems by a rational coupling of plasmonic Au NPs and photocatalytic active MOFs into a core-shell structured nanocomposite. The resulting nanocomposite shows improved photocatalytic performance under visible light, generating more active radicals. The removal of the capping agent further enhances the photocatalytic performance.

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 one-dimensional Au core@AuPt0.20Rh0.08 alloy shell nanowires (Au@AuPt0.20Rh0.08 CS-NWs) with long aspect ratio and cross-linked network architecture were synthesized, showing excellent electrocatalytic performance for ethanol oxidation reaction. The trimetallic synergistic effect between Au, Pt, and Rh atoms was responsible for the higher peak current density, better resistance to CO poisoning, and more lasting stability of Au@AuPt0.20Rh0.08 CS-NWs compared with Au@AuPt0.28CS-NWs and commercial Pt black electrocatalyst.

Summary: Three factors in designing an excellent heterogeneous tandem catalyst include sequencing, proximity, and compatibility, which can be achieved by changing the packing style or designing the nano/micro structure. Core-shell structures are considered ideal candidates for heterogeneous tandem catalysts due to their excellent capacity to balance the aforementioned three factors.

Summary: Controlling the growth, structure and morphology of core-shell nanoparticles (NPs) is significant for catalytic applications and can be achieved by adding chemical additives to the synthesis reaction mixture. This study using in situ liquid cell transmission electron microscopy (TEM) reveals the overgrowth mechanisms of Ag on Au nanobipyramids in AgNO3 aqueous solution with ascorbic acid as the reducing agent, helping to understand the dynamics of the coalescence process of Ag NCs upon addition of PVP. This research is valuable for synthesizing NPs with greater design flexibility and expanding their various technological applications.
