چکیده مقاله :
Caffeine loaded magnetic nanoparticle was successfully synthesized and were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy dispersive X-ray analysis (EDX), thermo gravimetric analysis (TGA), differential thermal analysis (DTA) and vibrating sample magnetometer (VSM). The resulting nanocomposite is shown to be an efficient catalyst in Knoevenagel condensation of various aldehydes under ultrasound irradiation.
