Summary: This study investigates the size effect of plasmonic Au@Pd core-satellite nanoparticles on the photocatalytic formic acid (FA) dehydrogenation under visible light. The results show that the smallest nanoparticles with the highest absorption/extinction ratio possess the best catalytic performance. Additionally, large nanoparticles with high scattering exhibit unexpectedly enhanced activities by raising the reaction temperature or shortening the interparticle distance.

Summary: This work develops an atomistic method to predict the population of hot-carriers in large nanoparticles under continuous wave illumination. By solving the equation of motion of the density matrix and considering both excitation and relaxation effects, the study finds that the population of highly energetic carriers depends on material and nanoparticle size.

Summary: Researchers proposed to manipulate the emission rate of a single-photon emitter using detuned resonant nanocavities, and found that the plasmon-induced transparency effect can significantly enhance the emission rate of the emitter through simulation. This ultrafast single-photon emitter has diverse applications in the field of quantum information and quantum communications.

Summary: Previous studies have shown that the nano-crystallization process affects the luminescence properties of nanocrystals. This project explores the influence of nanocrystal size on the electrical and optical properties of Cr2+:ZnSe nanowires. A first-principles study of Cr2+:ZnSe nanowires with different sizes was conducted. It was found that the Cr2+ ion prefers to reside at the surface of ZnSe nanowires and as the nanocrystal size decreases, a significant short-wave-length shift in absorption was observed.

Summary: We demonstrate a significant enhancement of the Faraday effect in a magnetoplasmonic nanocomposite based on Au nanoparticles and a bismuth-substituted iron-garnet film. The Faraday effect is enhanced by more than 20 times compared to the same bare magnetic film due to the excitation of localized plasmon resonances in the Au nanoparticles.

Summary: Peptoids, with a structure similar to proteins, offer a versatile platform for assembling structures with atomic precision. This study demonstrated successful assembly of CdSe QDs using peptoid tubes and sheets via covalent linkages, providing control over QD density. The compatibility and control of CdSe-peptoid interactions through varying peptoid structures and CdSe particles were shown to create complex hybrid structures.

Summary: Sodium citrate-stabilized gold nanoparticles can be destabilized in cell culture media, leading to their aggregation and formation of a protein corona. The presence of certain substances, such as antibiotics, can alter the formation and composition of the corona, resulting in changes in nanoparticle uptake.

Summary: A detailed study on the bandgap dependence of spherical Ge-rich GexSi1-x nanocrystals was conducted using atomistic density functional theory calculations. The results show a composition invariance of the bandgap diameter dependence, with the bandgap of NCs being well described by a power function for a certain diameter range. H-passivation of the NC surface helps accurately determine the NC bandgap by excluding surface states near the band edges.

Summary: This study investigates the transmission of a two-level quantum emitter in its ground state through a graphene nanosheet and the nonadiabatic process produced by the graphene plasmons field distribution. It reveals a significant probability of exciting the quantum emitter and simultaneously emitting a GP, especially at speeds around 10^-4 times the speed of light. Furthermore, accelerated emitters cause GPs to exhibit a thermal field photon distribution with high temperature, providing a platform for observing the dynamical Casimir effect and simulating the Unruh effect.

Summary: High-photoluminescence graphene quantum dots were synthesized through a simple one-pot hydrothermal process and separated using dialysis bags of different molecular weights, resulting in four GQDs with varying sizes. As the size of the separated GQDs decreased, the intensity of the emission peak became stronger, with the smallest GQDs showing the most energetic PL intensity among the four separated GQDs. The PL energy of all separated GQDs shifted slightly, as supported by density functional theory calculations.

Summary: Carbon quantum dots (CQDs) are an important complement to traditional quantum dots, with characteristics of low toxicity, easy preparation, low cost, and good biocompatibility. CQDs of various colors have been successfully prepared using a one-step solvothermal method, and their diameter satisfies the quantum size effect. The red-shift in CQDs is attributed to carbon-/oxygen-related surface defects. Furthermore, CQDs-based LEDs devices have been fabricated, illustrating their great potential for future luminescence applications.

Summary: This article summarizes the properties of colloidal semiconducting nanocrystals with a single-crystalline structure, which are largely influenced by their surface structure at the atomic-molecular level. Although there is a lack of understanding and control over the surface structure, the three spatial zones of the nanocrystal surface (crystal facets, inorganic-ligands interface, and ligands monolayer) can be studied using advanced experimental techniques and theoretical calculations. The surface ligands and their bonding modes are facet-specific, and the solubility of nanocrystal-ligands complexes is determined by the ligands monolayer. The molecular environment surrounding each nanocrystal plays a critical role in their properties.

Summary: Plasmonic cavities can confine electromagnetic radiation to deep sub-wavelength regimes, allowing for strong coupling phenomena with individual quantum emitters. By studying scattering spectra and using interferometry, researchers observed Rabi splitting and non-classical emission in devices with semiconductor quantum dots, revealing complex interactions between bright and dark states. Model simulations based on an extended Jaynes-Cummings Hamiltonian explained the experimental findings, highlighting the potential of controlling quantum state dynamics through the coupling of quantum emitters to plasmonic cavities.
