Summary: The use of CNCs with AgNPs for various applications is common, and utilizing microwave-assisted generation of AgNPs on the CNC surface has been found to be useful in reducing synthesis cost and environmental pollution. The microwave method offers advantages of simplicity, speed, and high efficiency. This study demonstrates that the use of a green microwave-based method can rapidly synthesize AgNPs, showing good antibacterial properties with trace amounts of AgNO3.

Summary: This work describes the synthesis of five three-coordinate silver(I) complexes, which react with I-2 to form a pair of a four-coordinate silver(I) complex and a two-coordinate iodonium complex. Particularly, an I+⋯Ag+ interaction was observed in one of the pairs, representing a nucleophilic behavior of I+.

Summary: Silver exposure has been shown to negatively impact the neural and behavioral functions of fish, resulting in reduced physical fitness and impaired social, learning, and memory behaviors. This indicates neurotoxicity in adult zebrafish after exposure to sublethal levels of AgNO3 for 72 hours.

Summary: This study evaluated the effects of silver nitrate (AgNO3) and nano-silver (Ag-NPs) on the physiological and biochemical characteristics, and quality of grape bunches during cold storage. The results showed that both AgNO3 and Ag-NPs improved the longevity and quality of the fruits. Immersion in Ag-NPs was found to be the best application for maintaining overall storage quality for both grape varieties.

Summary: A study in French university hospitals found a higher prevalence of poppers consumption among patients with high levels of MetHbia, with an increase in poppers consumption after legalization. The research suggests a relationship between poppers use and severe side effects, such as MetHbia.

Summary: In this study, organomodified montmorillonite and halloysite nanoclays were used to enhance intercalation characteristics, and Ag+ ions were doped to enhance antimicrobial properties. Various analyses showed that the interlayer space of the nanoclays increased and Ag+ ions successfully doped into the nanoclay structure. Additionally, MMT-type nanoclay samples released more Ag+ ions compared to halloysite-type nanoclay samples. The results demonstrated that intercalated and Ag+-doped nanoclays effectively inhibited bacterial growth.

Summary: Silver nanoparticles (AgNPs) are commonly used in consumer products for their antimicrobial properties and can enter aquatic ecosystems through wastewater. This study investigated the toxicity of AgNPs and AgNO3 on Lemna minor at different initial frond densities. Results showed that plants at higher initial frond densities were more sensitive to silver, with lower growth rates observed in both silver treatments. Competition and crowding at high frond densities resulted in reduced growth in the presence of silver.

Summary: This study aimed to investigate the damage caused by silver nanoparticles (Ag NPs) and silver nitrate (AgNO3) to land slugs. The results showed significant changes in biochemical, antioxidant, lipid peroxidation, and DNA fragmentation indicators after exposure to Ag NPs and AgNO3 for 15 days. Histopathological alterations were also observed in the digestive glands.

Summary: The study examined the effects of exposure to un-coated AgNPs or silver nitrate on the benthic deposit-feeding polychaete Capitella teleta. The results showed tolerance towards both AgNPs and AgNO3, with significant effects on reproduction and growth observed after eight weeks. Further investigations into the long-term effects of un-coated AgNPs on sediment-dwelling organisms are needed.

Summary: This study investigated the physiological consequences of transient exposure to silver ions on two strains of Saccharomyces cerevisiae. The results showed that S. cerevisiae is capable of producing silver nanoparticles even at high levels of exposure, and coexposure to copper and silver significantly increased intracellular copper, silver, and calcium. Electron microscopy images revealed the shrunken and distorted physical appearance of treated cells.

Summary: This study investigates the electrochemical reduction of nitrate in the presence of silver metallic particles (AgMPs). The results show that the presence of AgMPs significantly improves nitrate removal and conversion. The effects of various parameters on nitrate removal and selectivity are also studied. Additionally, AgMPs exhibit reusability.
