Summary: A series of face-centered cubic-based silver nanoclusters were studied by varying the halogen atom in the thiolate ligand to investigate the influence of halide atoms on the electronic structure. These clusters are emissive at room temperature, with luminescence intensity increasing as temperature decreases, predominantly originating from interband relaxation of the silver cores.

Summary: The structure-property correlation of a series of silver nanoclusters reveals a strong relationship between the optical and electrochemical bandgap values and the electronic effect of halides, governed by intracluster and intercluster pi-pi interactions. Emission from these clusters at room temperature is predominantly due to interband relaxation of the Ag cores, with femtosecond transient absorption spectra showing decay profiles dominated by relaxation to surface states. This sheds light on the molecular-like dynamics of these nanoclusters with a face-centered cubic core.

Summary: This work presents a method for controllably creating silver micropatterns by laser-induced photosculpting. The process involves plasmonic interactions between pulsed laser radiation and silver nanorods, leading to the formation of well-defined 3D structures known as Airy castles. The structures contain emissive Ag nanoclusters, allowing for the examination of the aggregation process using luminescence microscopy. The study comprehensively examines the factors that define the photosculpting process and investigates the potential applications of Airy castles.

Summary: In this study, newly obtained atomically precise phosphine-thiolate protected Au-11-SH and cationic Au-13-SH with a unique aromatic ligand (quinoline-2-thiol) were used to reveal the origin of luminescence in metal nanoclusters. By comparing with the traditional phosphine-halide-protected Au-11-Cl and Au-13-Cl, it was found that the conversion of chloride to thiol triggered room-temperature luminescence in Au-11 and modulated the luminescence behavior of Au-13. Ultrafast UV/IR spectroscopy and transient absorption spectroscopy provided insights into the relaxation process from ligand to core state, affecting the dynamics of excited states and intermediate states, leading to efficient room-temperature emission. The findings have implications in the fields of lighting, light harvesting, and photocatalysis.

Summary: Functional superstructures constructed from metal nanoclusters (MNCs) have great potential in applications such as tunable photoluminescence, catalytic activity, photothermal stability, and biological functionality. However, their controlled synthesis with well-defined size, structure, and properties poses a significant challenge. This study introduces a novel approach that combines depletion attraction and thermal activation to induce the in situ formation of spherical superclusters (AuSCs) from Au(I)-thiolate complexes within the assembly. Extensive characterization and electron tomographic reconstruction reveal that Au(I)-thiolate complexes can be sequentially transitioned into metallic Au(0), resulting in hollow nanoshell-like structures with consistent size and diverse shell configurations.

Summary: A series of doped gold superatoms M@Au-12 were synthesized and the Ru@Au-12 superatom exhibited room-temperature phosphorescence in deaerated dichloromethane with a quantum yield of 0.37. Density functional theory calculations suggested that the efficient phosphorescence is attributed to rapid intersystem crossing between singlet and triplet excited states with structural and energy similarities.

Summary: In this study, we synthesized PAA-Ca(Eu) nanoclusters as a luminescence sensor for phosphate ion detection. The nanoclusters showed a well-dispersed and dot-like morphology under high resolution transmission electron microscopy. They exhibited a significantly higher sensitivity for phosphate ion compared to other anions, and the luminescence intensity had a linear increase with the concentration of phosphate ion. The nanoclusters have the potential to be used as a luminescence sensor for quantitative detection of phosphate ion.

Summary: Faradic electrode-directed capacitive deionization (faradic-based CDI) is a green and eco-friendly technique with potential in addressing freshwater crisis. However, its practical applications are limited by slow desalination kinetics. In this study, a synergetic strategy combining material design and cell architecture was proposed to improve the desalination rate limit of faradic-based CDI. The integration of ultrasmall Bi nanoclusters impregnated carbon nanofibers as electrodes and a flow-through CDI system resulted in super-fast desalinization and excellent cyclic stability. This research opens up new possibilities for highly-efficient desalination systems based on faradic-based CDI.

Summary: Doped carbon materials, especially F-doped carbon catalysts, have gained significant attention as metal-free catalysts for oxygen reduction reactions and as corrosion-resistant supports for Pt and non-Pt nanoparticles. F-doped carbon materials possess unique properties and greatly improve the activity and durability of the ORR compared to N-doped carbon materials. The high electronegativity of F-doping can efficiently modify the electronic band structure of carbon materials, favoring the ORR. This review systematically discusses the effect of F-doping/F co-doping on the electrocatalytic reduction of O2 in acidic and alkaline conditions, the stability and durability of fuel cell catalysts, and provides guidelines for working with F-doped carbons. Future research directions on F-doped carbons are also proposed to bridge the gap between laboratory-scale assessments and commercial applications.
