Biogenic Synthesis of Silver and Iron Nanoparticles Derived From Grewia Optiva Leaf Extract: A Novel Approach for Antidiabetic, Anticoagulant and Anti‐Inflammatory Therapies

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT This study presents the green synthesis of silver (Ag‐NPs) and iron nanoparticles (Fe‐NPs) using aqueous leaf extract of Grewia optiva as a natural reducing and stabilizing agent. The extract was prepared using a Kjeldahl apparatus under controlled heating. Nanoparticle synthesis was optimized by varying pH, temperature, and salt concentration,

From fertilizer to insecticide: urban leaf litter chemistry alters the survival landscape of Aedes aegypti

Pest Management Science, EarlyView.
Chemical profiling and bioassays reveal that leaf‐litter leachates from urban trees flip between nourishing and killing Aedes aegypti larvae: dilute Tipuana tipu boosts growth, whereas concentrated, aged extracts are >90% lethal. Species‐specific chemistry thus turns street trees into potential self‐renewing tools for integrated vector control ...
