Green Approach to Synthesis of Pt and Bimetallic Au@Pt Nanoparticles Using Carica Papaya Leaf Extract and Their Characterization
This study reports a green approach to synthesis of monometallic platinum nanoparticles (Pt NPs) and bimetallic aurium@platinum nanoparticles (Au@Pt) using aqueous leaf extract of Carica papaya as a reducing and stabilizing agent. The nature and morphology of as-synthesized PtNPs and bimetallic Au@Pt NPs were characterized using UV/vis spectroscopy (UV–vis), high resolution transmission electro...
متن کاملتهیه، مشخصهیابی و ارزیابی مقایسهای زیست فعالی سه نوع نانو پودر شیشه زیست فعال برای کاربردهای پزشکی
Fabrication of biomaterials with ability to form a bond with bone tissue for bone skeletal system repair is one of the biomaterial science aims. Bioactive glasses containing CaO-SiO2-P2O5 are among the most important groups used in biomedicine and dentistry such as bone defect repair and maxillo-facial reconstruction. The aim of this work was preparation and characterization of nano particle b...
متن کاملSynthesis and characterization of Alumina (Al2O3) nanoparticles prepared by simple sol-gel method
Alumina is one of the most widely used ceramic materials as catalysts, catalyst supports and absorbents, and also wear resistant coating. This study focused on fabricating and characterizing of alumina ceramic nanoparticles fabricated using new and simple sol-gel method. Aluminium oxide (Al2O3) nanoparticles were synthesized by iron (III) nitrate 9-hydrate as precursor. Physicochemical properti...

متن کاملSTUDY OF OIL SPILL ON THE SEA SURFACE IN THE PRESENCE OF THERMAL AND CONCENTRATION BUOYANCY EFFECTS
Pollution occurs when the concentration of various chemical or biological constituents exceed a level implying negative impact on amenities, the eco-system, resources and human health. Oil spills are the serious environmental hazards which often exhibit long-term impacts. The main objective of response to an oil spill is to reduce its impact on nature and human health. This paper allows us to...
