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,

Inversion tectonics in central Alborz, Iran

Journal of Structural Geology, 2006
Abstract Structural analyses carried out in the southern-central Alborz (Iran) have shown that the evolution of this belt has been strongly conditioned by the inversion of pre-existent extensional faults. Inversion tectonics has been identified especially in the southern part of the belt, and it is related to the reactivation of grabens formed in the
