Summary: This study presents a simple photo-induced synthesis method for the production of Glyco-UAuNPs using a reliable microfluidic approach at room temperature. The method eliminates the need for chemical reductants, templating agents, or co-solvents and demonstrates good feasibility and stability. Using nuclear magnetic resonance spectroscopy, the study shows a linear correlation between the exposed thiol ligands on the UAuNPs and the ligand concentration in the initial mixture, providing a precise design method for engineered UAuNPs or smart hybrid nano-systems.

Summary: Nanoscale assembly of ultrasmall metal nanoclusters using molecular forces has been shown to be a powerful strategy to manipulate their properties in various dimensions. In this study, we demonstrate the formation of kinetically trapped assemblies with enhanced photoluminescence and extended this principle to other materials. We also show a thermal energy driven process to isolate these assemblies, which exhibit thermodynamic stability and unique properties. Our strategy may have broader applications in creating different MNC-based assemblies with unforeseen arrangements and properties.

Summary: Nanoparticle-assisted nuclear magnetic resonance (NMR) chemosensing is a technique that uses monolayer-protected nanoparticles as supramolecular hosts to detect small molecules in complex mixtures. The structure-sensitivity relationships that determine the detection limits of this technique are still not well understood. This study combines NMR spectroscopy and atomistic molecular dynamics simulations to investigate the factors that affect the sensitivity of different NMR chemosensing experiments. The results show that the intensity of the observed signals is correlated with the spin-spin interactions between the analytes and the nanoparticles, as well as the analytes and the nanoparticles' solvation molecules.

Summary: The authors report a mechanism by which mitotically quiescent proximal tubular epithelial cells eliminate gold nanoparticles from the kidneys. This mechanism involves squeezing balloon-like extrusions through microvilli, transporting gold-containing endocytic vesicles along with organelles into the extrusions, and pinching the extrusions off the membranes into the lumen. This organelle-extrusion mechanism represents a new route for nanoparticle elimination.

Summary: Gold(II) complexes have been less utilized in catalysis compared to their gold(I) and gold(III) counterparts. However, gold(II) complexes offer potential in homo-coupling and cross-coupling reactions, as they are more easily accessible through simplified oxidation and reduction processes. Gold(II) exhibits characteristics of both soft acid gold(I) and hard acid gold(III). This review explores the unique reactivity and potential applications of gold(II) species, highlighting their significance in catalytic transformations.

Summary: A new aryl selenonium polyoxometalate hybrid was developed and compared with an aryl sulfonium polyoxometalate hybrid in terms of their photocatalytic properties. It was found that the aryl selenonium hybrid exhibited better catalytic performance, which could be attributed to the larger atomic radii of selenium stabilizing the photogenerated electron-hole pair more efficiently. Additionally, the generation of elemental selenium through cleavage of C-Se bonds during catalysis was observed.

Summary: In this work, two metal organic frameworks (MOFs) containing {Cu2I2} clusters, Eu-CuI-INA and Sr-K-CuI-INA, were synthesized and characterized. Both materials have a three-dimensional structure with {Cu2I2} clusters coordinated by INA(-) ligands and Eu3+ or Sr2+ ions. The Sr-K-CuI-INA material exhibited sensitive fluorescence sensing behaviors towards cysteine and nitro-bearing molecules, showing potential applications in bio and explosive molecule sensing. This work provides a good reference for designing fluorescent MOF probes containing CuI molecules.

Summary: Na-ion batteries (NIBs) have attracted great interest as a potential technology for grid-scale energy storage due to the wide distribution, low cost, and environmental friendliness of sodium resources. However, their implementation is hindered by low rate capability and cycling stability caused by the large ionic size of Na+. In this study, a three-dimensional nanoarchitectured coral-like CoSe2@N-doped carbon (CL-CoSe2@NC) was synthesized, and it exhibited improved sodium storage properties with better electrode kinetics and a stable SEI film.
