Summary: This study investigates the effect of copper and titanium dioxide nanoparticles as a substrate on the optical response of double negative-index plasmonic metamaterials layers. The thin-film characterizations were analyzed using various techniques, and the optical properties of the films were described using the film matrix method, confirming the optical gain property of the fabricated layers.

Summary: The vibrational properties of metallic nano-objects are influenced by factors such as size, shape, material, crystallinity, and coupling with the environment. This study reveals that the contact area between a nano-object and its substrate affects the vibrational response of gold disks. Additionally, it demonstrates that nano-disks can be excited by acoustic waves propagating from the substrate, suggesting the potential use of nanodisks in developing nanoscale acoustic microscopy.

Summary: This study investigates the influence of plasmonic (gold) and non-plasmonic (palladium) nanostructures on the photocatalytic activity and redox properties of titanium dioxide. The results show that palladium primarily determines the activity of modified materials, while the surface plasmon resonance of gold has no effect on the activity. Moreover, the nanostructures induce changes in the redox properties of the semiconductor, regardless of their plasmonic or non-plasmonic nature.

Summary: This study introduces a novel strategy for assembling gold nanoparticles into chainlike structures and investigates the role of ethylamine in the assembly process. It is found that the volume ratio of ethanol/water affects the assembly speed and length of the chainlike assemblies, and the primary amine is essential for AuNP assembly. Additionally, the study proposes possible mechanisms for controlling AuNP assembly through surface engineering.

Summary: In this study, an all-optical pump-probe method was used to develop a mass-sensing mechanism in a molecular plasmonic system at room temperature. The results showed that the intensity of the probe-field transmission spectrum can be significantly enhanced by engineering the material features of the plasmonic nanostructure.

Summary: The optical properties of nanoparticle assemblies are influenced by the unique characteristics of their building blocks and spatial organization, leading to emergent phenomena. A fast, materials agnostic method has been developed to simulate the optical response of large nanoparticle assemblies with structural and compositional complexity. This method overcomes the limitations of conventional electromagnetic simulations and achieves rapid and accurate convergence for complex configurations, enabling the design of complex and hierarchically structured assemblies with desired optical characteristics.

Summary: This study focuses on the optical properties of gallium alloy nanoparticles in liquid plasmonics. The effects of different core-shell structures on localized surface plasmon resonance are investigated. Mie theory and discrete dipole approximation methods are used to analyze the optical behavior of gallium alloys of various sizes and shapes. The results show that GaAg and GaAl alloys exhibit good plasmonic behavior and can be used as alternative materials to GaIn in energy storage devices and soft electronics.

Summary: This study numerically investigates the influence of surface roughness on the plasmonic properties of aluminum nanodisks, revealing different effects on the out-of-plane quadrupolar mode and in-plane dipolar mode. The results show that increasing surface roughness significantly dampens the quadrupolar mode while broadening and redshifting the dipolar resonance. These effects are attributed to the decoherence and dissipation of electronic oscillations due to surface roughness, and are experimentally confirmed by characterizing the optical properties of periodic aluminum nanodisk arrays.

Summary: The study examines the impact of adhesion on the chemical potential of supported nanoparticles, showing that the chemical potential is influenced by adhesion energy and particle volume. The use of hemispherical particle shape provides a good approximation for the chemical potential, with an error of less than 10% for contact angles between 66 and 120 degrees.

Summary: This article reviews recent developments in the synthesis of gold nanostructures with multiple hot spots and Au-based heterostructures for plasmon-induced sensing and photocatalysis. Gold nanostructures with multiple hot spots exhibit enhanced molecular sensing and surface-enhanced Raman scattering performance, while Au-based heterostructures have shown great promise in photocatalytic reactions. The rational design of these nanostructures can lead to enhanced sensing and photocatalysis.

Summary: Understanding the plasmonic coupling between metallic nanoparticles (NPs) in a 2D array and the effect of a semiconductor substrate is crucial for optimizing optoelectronic structures. This study presents a simple semi-analytical approach based on the discrete dipole approximation (DDA) to simulate the far-field and near-field properties of NP arrays, taking into account particle coupling and the presence of a semiconductor substrate. The method is validated for Ag NP dimers and single Ag NPs on a GaN substrate, and then applied to square and random arrays of Ag NPs. It is found that increasing the NP surface density on a GaN substrate results in a redshift of the dipolar resonance frequency and enhanced near-field properties. The single dipole approach used in this model allows for efficient computational times, making it advantageous for predicting optical properties in large NP arrays on semiconductor substrates for various applications.

Summary: Bimetallic Ag-Au/TiO2 nanocomposites were synthesized by sequential photodeposition. The photocatalytic activity of the bimetallic nanocomposites outperformed monometallic nanocomposites, which was attributed to the Au-core-Ag-shell nanoparticle morphology. Reversing the photodeposition order resulted in Ag-Au alloy nanoparticle morphology, but alloying was not beneficial to the photocatalytic activity.
