Summary: In this study, Rh2O3 nanoparticles were implanted on the surface of reduced graphene oxide (RGO) by a hydrothermal reaction. Sensitized by Eosin Y, Rh2O3 was converted into metal Rh, forming a strong interaction interface between Rh NPs and RGO. The fabricated Rh/RGO catalyst showed high performance for photocatalytic H-2 evolution under visible light irradiation, with a H-2 evolution rate of 98.1 mmol center dot g(-1)center dot h(-1) and a maximum apparent quantum efficiency of 79.3% at 520 nm. The enhanced performance was attributed to the excellent electron conduction ability of RGO and the strong interaction between Rh NPs and RGO, which accelerated electron transfer and prolonged charge lifetime. The strong interaction also ensured the strong anchoring and excellent stability of the Rh/RGO catalyst.

Summary: Properly engineered heterojunction photocatalysts can effectively separate photoexcited electron-hole pairs and improve the photocatalytic hydrogen evolution performance. In this study, 3D bicontinuous nanoporous reduced graphene oxide (np-rGO) was used as a supporting matrix for CdS nanoparticles to achieve a highly efficient photocatalysis system for hydrogen production. The bicontinuous internal ligament and open nanopores in the 3D nanoporous heterojunction contribute to improved light absorption and utilization capacity. The construction of a p-n heterojunction with staggered band alignment in CdS/np-rGO accelerates the transport of photo-excited carriers, leading to a significant increase in hydrogen generation rate.

Summary: Dermaseptin B2 (DRS-B2) is an antimicrobial peptide secreted by the Amazonian tree frog, Phyllomedusa bicolor. This study demonstrates that adsorption of DRS-B2 onto alginate nanoparticles enhances its antibacterial activity, particularly against colistin-resistant strains of Escherichia coli. The addition of lactic acid or menthol further enhances the antibacterial activity of this new formulation. Safety and stability tests conducted on human erythrocytes and eukaryotic cell lines indicate the potential of these formulations as alternatives to antibiotics for treating Gram-negative bacterial infections such as E. coli.

Summary: In recent years, there has been a significant increase in the number of studies focusing on the synthesis and characterization of deep eutectic solvents (DESs). DESs, known for their stability, ease of synthesis, and ability to tailor properties, are considered one of the greenest solvent families used in various fields such as organic synthesis, catalysis, electrochemistry, and medicine. However, there is a lack of research on specific groups of DESs, particularly those comprising organic acids (OA-DESs), despite their potential in biomedical applications. This review aims to highlight the importance and applications of OA-DESs as antimicrobial agents and drug delivery enhancers, providing valuable insights for future developments in this field.

Summary: This work investigates the properties of Ag-containing lead-boro-phosphate glasses in terms of structure, optics, refractive index dispersion, and shielding. It is found that Ag NPs precipitation occurs, as evidenced by XRD patterns and TEM images. The formation of Ag NPs leads to a depolymerization process and an increase in glass density, as well as a reduction in optical band gap energy. The optical performance of the glass is improved due to the formation of Ag NPs, making it suitable for various multi-functional optical devices.
