Summary: The study presented the synthesis and luminescent features of three gold(I)-N-heterocyclic carbene complexes to investigate the influence of the n-alkyl group on luminescence properties in the crystalline state. The results showed that the n-alkyl group can lead to emission shifts in the solid-state luminescence spectra.

Summary: The use of N-heterocyclic carbene (NHC) ligands instead of phosphine ligands in gold clusters can lead to ligand-specific photophysical properties, with intramolecular C-H···Au interactions as a key structural feature. NHC ligands produce clusters with nearly identical metal kernels but significantly different luminescent properties compared to phosphine ligands. Extension of the pi-conjugated system of NHCs can result in significant changes in absorption coefficient and emission wavelength.

Summary: A series of gold(I) and silver(I) complexes were synthesized and their antibacterial activities were tested. The gold(I) complexes showed good activity against Gram-positive bacteria, with the complexes of the 1,2,4-triazolylidene ligands being more active. The silver(I) complexes exhibited good antibacterial activity against Acinetobacter baumannii. High levels of antibacterial activity were observed against multi-drug resistant bacterial strains for both the gold(I) and silver(I) complexes. Resistance to these metal-containing complexes was less likely to develop compared to the widely used broad-spectrum antibiotic. Furthermore, the stability of these complexes was investigated, revealing possible decomposition reactions for silver complexes in aqueous solution.

Summary: Silver N-heterocyclic carbenes (Ag-NHCs) have good biocompatibility and are widely used in medicine and coordination chemistry, but their coordination with silver can weaken the Lewis acidity of Ag(I), resulting in slow development as catalysts. Future opportunities lie in further research on the catalytic mechanisms of Ag-NHCs to enhance their catalytic activity.

Summary: Solid supported or ligand capped gold nanomaterials (AuNMs) have emerged as versatile and recyclable heterogeneous catalysts for a broad variety of conversions in the ongoing catalytic 'gold rush'. AuNMs, existing at the border of homogeneous and heterogeneous catalysis, have the potential to merge high catalytic activity with significant substrate selectivity. This work summarizes well-defined catalytically active NHC capped AuNMs, including spherical nanoparticles and atom-precise nanoclusters, as well as the important NHC design choices towards activity and (stereo-)selectivity enhancements.

Summary: This study investigated the aromatic properties of gold benzimidazole and cycloheptaimidazole N-heterocyclic carbenes through computational calculations, revealing a minor difference between the two families with family 1 being slightly more aromatic. The high stability of the gold atom's molecular orbitals in the complexes resulted in almost no contribution from the metal to the observed UV-Vis transitions.

Summary: A Brønsted basicity scale was established for nine representative N-heterocyclic olefins (NHOs) using an UV-visible spectroscopic method. The unsaturated NHOs were found to have stronger basicities compared to their N-heterocyclic carbene (NHC) analogues, while the basicities of the saturated NHOs were weaker. The nucleophilicity of the NHOs was also stronger than commonly used Lewis bases but weaker than their NHC analogues.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.

Summary: The development of the textile industry has raised concerns due to the contamination of drinking water by organic dyes, which pose a carcinogenic risk to humans. Nanomaterials, particularly semiconductors, have been utilized for photocatalytic degradation of dye pollutants. Various parameters, such as catalyst dosage, irradiation time, light sources, initial dye concentration, temperature, and pH, play significant roles in the degradation process. Different generations of photocatalytic nanomaterials, including single metal nanoparticles, binary and ternary metal oxides, as well as inert solid substrates with photocatalysts, have been employed for dye degradation.

Summary: Panax ginseng, as an ethnomedicinal plant, has therapeutic effects in traditional medicine. This study investigated the potential use of green-synthesized silver nanoparticles from Panax ginseng leaf extract for the treatment of lung carcinoma and heart protection against mitochondrial dysfunction and cardiac dysfunction in obese insulin-resistant rats. The silver nanoparticles showed spherical morphology with a size range of 12.11 to 43.33 nm. In vivo experiments demonstrated that the silver nanoparticles significantly improved metabolic parameters, heart rate variability, cardiac function, and cardiac mitochondrial function in the rats. This study suggests that silver nanoparticles derived from Panax ginseng have cardioprotective effects.

Summary: Nanozyme based sensors have been developed as an effective method for detecting harmful metal ions in water samples. In this study, a Co(II) based coordination polymer nanoparticle (Co-CP NP) was synthesized and utilized as a nanozyme to detect Fe(II) ions selectively. The Co-CP NP exhibited peroxido-reductase mimicking activity, and the detection limit for Fe(II) ions was found to be 0.66 μM. The catalytic action of the Co-CP NP was further analyzed using Michaelis-Menten kinetics, and the detection mechanism was elucidated through XPS and zeta potential analysis.
