Summary: The research indicates that the absorption peaks of DNA-templated Ag nanoclusters are sensitive to the assembled distances and exhibit characteristics of plasmon coupling; TDDFT simulations suggest that the absorption originates from plasmons, and the consistent trend between experimental and simulation results implies the possibility of plasmon coupling. DNA-AgNCs have the potential to be promising materials for constructing plasmon-coupling devices with ultra-small size, site-specific and stoichiometric binding abilities, and biocompatibility.

Summary: In this study, the stability and antibacterial activity of silver nanoparticles (AgNPs) coated with different stabilizers were investigated. The AgNPs showed differences in stability and size change depending on the coating agent used. The stabilizer may function as a growth controller of the nanoparticles, affecting their biological properties. The protective or stabilizing agents also played a role in the antibacterial capacity and stability of AgNPs over time.

Summary: Room-temperature sodium-sulfur batteries have high potential for energy storage, but issues like low S mass loading and poor cycling stability limit their capacity. This study successfully synthesized sulfur-doped graphene frameworks supporting 2H-MoS2 and Mo-1, leading to a cathode with record-high sulfur mass loading and excellent cycling stability. Experimental and computational results revealed the enhancement mechanisms.

Summary: In this study, an antibacterial and anti-inflammatory wound dressing based on riclin and silver nanoparticles was developed. The results showed that the dressing had sustained release of silver nanoparticles, effectively suppressed pathogen growth, and had negligible toxicity to human cells. In addition, it promoted faster and smoother wound healing while reducing the expression of inflammatory mediators.

Summary: This study focuses on the bactericidal activity of nano-silver particles synthesized using wattle and quebracho as reducing agents. The formation of wattle-mediated nanoparticles (NW) and quebracho-mediated nanoparticles (NQ) has been confirmed structurally and morphologically. The bactericidal activity of NW and NQ against E. coli and B. cerus has been determined, and molecular simulations have been performed to study the interaction between NQ and E. coli 5i5H.

Summary: In this study, MnCo2S4 nanosheet catalyst was successfully synthesized and found to exhibit superior performance in hydrogen evolution. Compared to MnCo2S4, MnCo2S4 showed low overpotentials, moderate Tafel slope, and excellent sustainability. The outstanding performance can be attributed to the increased number of electrochemically active sites and enhanced electronic conductivity on the catalyst surface.

Summary: Networks are important for describing relationships between people, roads between cities, reactions between chemicals, and other interactions. Bipartiteness, dividing the network into two groups, can facilitate the study of the network's structure. We have developed an algorithm that can find a near-optimal bipartisation within a reasonable time frame and used it to uncover the hidden structure of the CSD cocrystal network.
