Summary: The chiroptical properties of silver nanowires assembled in helical nanostructures can be finely tuned over a broad wavelength range using simple design principles. The intensity of circular dichroism is controlled by the angle between the oriented nanowire layers, reaching ellipticity values higher than 13 degrees, while the shape of the circular dichroism spectra strongly depends on the spacing between the layers which can be tuned at the nanometer scale.

Summary: As the demand for digital security increases, physical unclonable functions (PUFs) have emerged as a potential solution for unique identifiers and cryptographic keys. However, conventional memory-based PUFs have limited encoding capacity, which can compromise their security. This study introduces an Ag nanowire-based PUF that offers a high encoding capacity by leveraging the intrinsic topology of the nanowire network. The ternary bit encoding method allows for more detailed differentiation of the internal topological connection structure of the PUF, resulting in a larger encoding capacity.

The dispersion of HxReO3 in aqueous solution enhanced LSPR intensity and wavelength. The HxReO3-CdS hetero-nanocrystals showed significantly higher photocatalytic hydrogen production rate compared to pure CdS, attributed to increased light absorption and electron transfer facilitated by HxReO3.

Summary: This study successfully prepared PbS-Au hybrids with high-index facets and strong light absorption, showing significantly improved SERS signals for Rhodamine B detection. By adjusting the size and amount of Au nanoparticles, the SERS detection limit was lowered to 10(-12) M with an analytical enhancement factor of 5.1 x 10(8). The recycling and self-cleaning properties under visible light irradiation were demonstrated, attributed to the broad plasmon absorption and fast charge transfer between Au and PbS, offering a potential way for efficient SERS substrates development.

Summary: Anisotropy is important in various material systems, but creating and controlling it has been a challenge. Polarization-addressed anisotropy is attractive due to its controllability, simplicity, and accuracy, but only a few material systems can achieve it. In this study, a polarization-dependent anisotropic etching system made of Au@oligomer core-shell nanoparticles was established. The etching process is faster along the polarization direction, resulting in shape anisotropy of the particles. This system has advantages of high selectivity, controllability, and versatility, opening up new possibilities for on-chip nanofabrication.

Summary: In this paper, Cu2-xSe-modified Au/Bi2Se3 hybrid nanoparticles with porous shells were prepared, and a Bi2Se3/Cu2-xSe Z-scheme heterojunction was formed. The hybrids exhibited broad and strong plasmon resonance absorption in the visible band due to the effective coupling between the Au core and semiconductor shells. The carrier lifetime of the hybrids could be tailored by adjusting the Cu2-xSe content. The 0.1-Au/Bi2Se3/Cu2-xSe electrode with the longest electron lifetime showed enhanced photoelectrochemical performance. Compared to pure Bi2Se3 and Au/Bi2Se3 nanoparticles, the porous Au/Bi2Se3/Cu2-xSe hybrid photoanodes demonstrated significantly increased photoconversion efficiency under simulated sunlight illumination, thanks to the cooperation of the Z-scheme heterojunction and plasmon resonance enhancement effects.

Summary: Nonlinear optical signals of metallic nanoparticle films reach a maximum at the percolation threshold. By depositing Ag nanoparticles on the percolating Au nanoparticle film, we constructed conductive Ag/Au bilayer films and compared their second harmonic generation (SHG) with that of single-component (Au or Ag) nanoparticle films. We observed a 680% SHG enhancement in the Ag/Au bilayer film compared to the percolating Au nanoparticle film, attributed to the cooperative effect of surface plasmon resonances, interband transitions, and the percolation effect. These findings provide a strategy for designing nonlinear photonic nanodevices with optimized performance.

Summary: This study demonstrates the controllable growth of Pt-Au nanoplates and Au@Pt nanorings with superior photothermal conversion efficiency. Hexagonal Au nanoplates are used as templates, obtained through a transformation reaction from Au nanotriangles. Pt-Au nanoplates are prepared by a site-selective growth of Pt on the rim of obtained hexagonal Au nanoplates. Subsequently, Pt nanorings are obtained by a selective etching of Au, and a regrowth of Au on the Pt nanorings leads to bimetallic Au@Pt nanorings. The improvement in photothermal effect can be attributed to the strong surface plasmon resonances and coupling between Au and Pt.

Summary: Photocatalytic water splitting for hydrogen production has been explored in energy science, but efficiency is often lacking. This study proposes a controlled synthetic strategy to develop concave gold nanorods (Au NRs) with enhanced photocatalytic performance. The concave Au NRs, synthesized in aqueous solution, exhibit high-index facets and unique plasmon resonance modes. By selectively growing Pt nanoparticles and CdS nanocrystals onto the Au NRs, the photocatalytic H2 production rate reaches as high as 21654.56 μmol•g^-^1•h^-^1, demonstrating the great potential of faceted metal nanostructures for efficient photocatalysis.

Summary: We report an effective method to synthesize dumbbell-like Au-PtCu solid and hollow nanorods, regulated by the unique surface capping and oxidation etching roles of copper ions. Dumbbell-like nanorods are prepared through site-selective co-deposition of platinum and copper on both tips of gold nanorods assisted by the capping effect of the CTAB-Cu+ complex to passivate the side surface. Hollow dumbbell-like Au-PtCu nanorods are formed through triggering the etching effect of copper ions by increasing the reaction temperature to 80°C. The manipulation of the morphology and extinction properties of the trimetallic Au-PtCu nanorods is demonstrated by adjusting the concentration of copper ions. Under excitation with a near-infrared 808 nm laser, the dumbbell-like Au-PtCu nanorods show excellent photothermal conversion, with a 3.1 times temperature increment (ΔT) compared to bare Au nanorods, while the hollow dumbbell-like Au-PtCu NRs demonstrate improved photocatalytic activity under xenon lamp irradiation. The capping and etching properties of copper ions were demonstrated to synthesize different Au-PtCu nanorods with improved photothermal and photocatalytic activities.

Summary: The collaboration of magnetic and electric plasmon resonance modes in cup-shaped metallic nanostructures leads to significantly broadened and highly tunable optical responses. Different morphologies of Au nanoshells exhibit two maximal SHG intensities, depending on the number and size of openings. Ag/Au and AuAg/Ag/Au open nanoshells show enhanced SHG intensities by adjusting the thickness of the metal shells.
