The catalyst has been characterized by FT-IR (Fourier-transform infrared spectroscopy), SEM (scanning electron microscope), XRD (X-ray diffraction), EDS (Energy-dispersive X-ray spectroscopy), BET (Brunauer-Emmett-Teller), TGA (Thermogravimetric analysis) and VSM (vibrating-sample magnetometer). The remarkable advantages of this methodology are easy work-up, short reaction times, high to excellent product yields, low catalyst loading and reusability of the catalyst.}, keywords = {Ultrasonic irradiation,Heterogeneous catalysts,Fe3O4,nanocatalyst,Bis-thiazolidinones}, url = {https://www.orgchemres.org/article_141375.html}, eprint = {https://www.orgchemres.org/article_141375_b1f20a333cec941164ecbf873a64175d.pdf} }
