Summary: The study presents a one-pot synthesis method for gold nano-objects by mixing a gold salt, dodecanethiol, and tetrazine. Utilizing a large excess of thiol results in obtaining 2 nm gold nanoclusters, while a smaller amount of thiol leads to the formation of larger nanoobjects. The role of thiol and tetrazine in stabilizing clusters and the mechanism of cluster formation are investigated through various techniques.

Summary: Due to the increasing prevalence of wounds caused by accidents, surgeries, burns, and chronic illnesses, such as diabetes, wounds remain an important medical concern. Biofilm-forming infectious bacteria can hinder the healing process and lead to prolonged infections, which are often associated with heightened antibiotic resistance. Therefore, the development of new materials for wound healing and dressing is necessary. Nanomaterials, with their small size and large surface area, offer unique properties that make them potentially useful for a wide range of applications, including antibacterial wound regeneration. Green synthesis of nanoparticles (NPs) has gained attention in the nanotechnology community due to its effectiveness and environmental friendliness. Green NPs have shown promise as wound healing agents, but a comprehensive review on the use of green-manufactured NPs for wound healing has been lacking. This study aims to discuss the current trends in wound healing through green synthesized NPs, filling this gap in the existing literature.

Summary: In this study, the synthesis, molecular structure, and catalytic activity of a Pt/Ag nanocluster stabilized by organic phosphine ligands and inorganic chloride ligands were reported. The nanocluster [PtAg18(dppp)6Cl8](SbF6)2 was facilely obtained through a one pot method. The structure of the cluster was characterized as the stabilization of a PtAg12-centered icosahedral core by the metalloligand of dppp-Ag-Cl, with chloride ions capping the surface Ag atoms and binding the core and surface motifs. The cluster exhibited high stability due to the presence of eight free electrons in its structure, and displayed unexpectedly high catalytic activity in hydrogenation reactions attributed to the exposure of surface metal sites.

Summary: This review discusses the role, physicochemical properties, potential applications, and toxicological effects of magnetic nanoparticles (MNPs) in complex biological systems. MNPs have been widely used in various industries, leading to increased interactions with biological organisms. However, the full impact of these particles on complex biological systems and the toxicology aspects of their biomedical applications remain unclear, with mixed and inconclusive results. A consolidative framework that considers the physicochemical properties and potential risks of MNPs is necessary for their future manageable applications.

Summary: A facile synthesis strategy was developed for the preparation of carboxylated leaning tower[6]arene (CLT6)-mediated gold nanoparticles (CLT6-AuNPs) without external energy sources and reducing agents. The CLT6-AuNPs, with controllable particle size due to the cavity structure of CLT6, exhibited good stability and excellent performance in label-free detection of diquat. The reduction mechanism of AuNP formation was revealed to involve the cleavage of some phenyl ether bonds of CLT6 to produce reductive phenols and reduce Au3+ to AuNPs.

Summary: Rapid and accurate chemical composition identification is crucial in chemistry. Optical absorption spectrometry has limitations in identifying complex chemical compositions, especially in nano-scale research. In this study, a machine-learning-based method is developed to identify the compositions of metal nanoclusters (NCs) from featureless spectra. The method achieves good matches and low error values on optical absorption spectra that are difficult for humans to interpret. This work opens up possibilities for precise identification of nanomaterials based on their optical properties.

Summary: The compound Ag-34, which contains a polyoxoniobate (PONb) template, was synthesized using the solvothermal method combined with volatilization. This is the first successful isolation of a silver cluster with PONb template. The luminescence, solution behavior, and solid-state stability of Ag-34 were extensively studied. Electrospray ionization mass spectrometry confirmed the integrity of Ag-34's skeleton in solution. Its unique luminescent behavior shows potential for temperature detection. This work is expected to inspire further research on PONb-templated high-nuclearity silver clusters.

Summary: The size, morphology and symmetry of supercrystals made of [Au-25(SR)(18)](-) nanoparticles can be altered by adjusting the surface dynamics of the particles. Excess tetraethylammonium cations play a crucial role in the formation of micrometre-sized hexagonal rod-like supercrystals, which are held together by SR-[Au(I)-SR](4) interparticle linkers. The resulting supercrystals can be systematically tuned by changing the concentration and type of the tetraalkylammonium cations.

Summary: The researchers discovered that suppressing the vibration of the metal core can enhance the emission intensity of luminescent metal nanoclusters. By rigidifying the surface and propagating strains into the metal core, they achieved a high absolute quantum yield of 90.3 +/- 3.5% for solution-phase gold nanoclusters. The rigidified surface influenced the low-frequency acoustic vibration of the metal core, resulting in a subtle change in vibration frequency and reduction in amplitude, thus inhibiting non-radiative relaxation and leading to strong emission.

Summary: The demand for Carbon Fiber Reinforced Polymer (CFRP) has been increasing in automotive and aerospace industries due to its excellent strength-to-weight ratio. However, milling CFRP is challenging due to its anisotropic and heterogeneous properties, resulting in brittle and dust-like chips. This study investigates the effect of cutting speed and conditions on tool wear during CFRP milling, using a 6mm diameter uncoated tungsten carbide tool with a helix angle of 30 degrees. The highest tool wear was observed at a cutting speed of 170 m/min in chilled air conditions.

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.
