  • - Polygonatum odoratum, a perennial herb in the Liliaceae family and a traditional Chinese medicinal plant, has been found to contain various active compounds such as polysaccharides and flavonoids.
  • - In May to June 2022, a stem spot disease was identified in P. odoratum plants in Changsha, China, affecting 40-50% of the plants and causing serious economic losses by stunting growth.
  • - Researchers collected symptomatic stem samples to identify pathogens, isolating two fungal strains that displayed rapid growth on a culture medium, which may contribute to understanding and managing the disease affecting these plants.

A well-defined Ag@AgCl nanocubes loaded on the reduced graphene oxide plasmonic heterostructure (Ag@AgCl/RGO) was facilely prepared by sacrificial salt-crystal-template process and ethylene glycol-assisted reduction. The Ag@AgCl/RGO heterostructure shows superior photocurrent response and stability under the visible light irradiation. The enhanced performance mainly attributes to the plasmon resonance effect of AgNPs by improving the absorbance and transfer of photogenerated electrons.
