Summary: A new synthetic approach using site-specific alloying has been revealed to acquire the atomic design of new functional Ag(i) nanoclusters. This approach allows precise control over the surface charge, size, and shape of the template, resulting in the self-assembly of Ag(i) with a similar core structure. The introduction of strongly interacted peripheral motif units enhances the rigidity of the cluster skeleton, reducing non-radiative transitions and facilitating room-temperature emission properties. The electron-donating effect of the peripheral motif units reduces the bandgap and influences intercluster charge carrier transport. This novel synthetic approach paves the way for well-functioning nanocluster design.

Summary: The composition and stratification of passive oxide films on multi-principal element alloys were investigated using X-ray photoelectron spectroscopy and time-of-flight secondary ion mass spectrometry surface analysis. The results showed that the alloys with Mo exhibit higher stability in Cl--containing solutions compared to the Mo-free alloy. Furthermore, pre-passivation in Cl--free conditions and Mo addition enhance the resistance of these alloys to passivity breakdown.

Summary: The study revealed that the joint toxicity of copper nanoparticles (CuNPs) and zinc oxide nanoparticles (ZnONPs) was greater than the single toxicity of CuNPs or ZnONPs in Daphnia magna, displaying an additive or more-than-additive effect. The presence of Suwannee River natural organic matter (SR-NOM) did not significantly impact the joint toxicity of CuNPs + ZnONPs, but enhanced the accumulation of CuNPs or ZnONPs in D. magna exposed to the MNP mixtures. Dissolved Zn-ions released from the ZnONPs were found to dominate the joint toxicity of CuNPs + ZnONPs in the presence of SR-NOM.

Summary: This study investigated the corrosion behavior and metal ion release of the Essure (R) permanent contraceptive implant during storage in different solutions. The results showed that the tin-silver solder corroded continuously in phosphate buffered saline and hydrogen peroxide solution, while the corrosion was minimal in formalin storage. This study provides important insights into the long-term performance and safety of the Essure (R) implant.

Summary: This study presents a simple preparative method for high efficiency water oxidation using surface-assembled Fe(OH)(x)/FeOx type colloidal catalytic thin-films, with or without post annealing. The catalyst annealed at 250 degrees Celsius shows remarkable stability and lower overpotential for water oxidation, making it a potential enduring, inexpensive and competent candidate for catalyzing water oxidation reaction under begin conditions.

Summary: In this study, bimetallic ZVI nanoparticles containing Cu, Ni, and Co were synthesized and used for the removal of selenate ions from simulated FGD wastewater. The relationship between the structure and reactivity of bimetallic ZVI nanoparticles in Se6+ reduction was investigated through various characterization techniques and selenate reduction kinetics. The importance of the standard reduction potential difference between two metals in bimetallic ZVI for galvanic reduction and the structural characteristics in Se6+ reduction were demonstrated.

Summary: Colloidal nanoparticles in tea infusion play an important role in the formation of tea cream. The study found that the rate of aggregation of green tea nanoparticles increases with decreasing pH values, and different metal ions have different effects on the nanoparticles. In addition, low temperature indirectly promotes the aggregation of nanoparticles. Under low temperature, the combination of epigallocatechin gallate and caffeine weakens the stability of nanoparticles.

Summary: The interface nature of composite catalysts significantly affects the behavior of the oxygen evolution reaction (OER). In this study, nanoarchitecture consisting of Fe-based metal-organic frameworks (MIL-53) and metal-phenolic networks was created. The presence of MIL-53 enhanced the adsorption ability for OH center dot in the nanoarchitecture, and the electron transfer between MIL-53 and Ni-phenolic networks optimized the bonding strength between Fe3+/Ni2+ and oxygen intermediate species, resulting in improved OER performance.
