synthesis, characterization, and catalytic performance of a novel pseudopolymeric magnetic nanoparticles bearing urea linkers were presented. After the synthesis of urea linker, it was applied for the synthesis of pseudopolymeric magnetic nanoparticles. The structure of the synthesized pseudopolymeric magnetic nanoparticles was confirmed by applying different methods including Fourier transform infrared (FT‐IR)

catalyst in organic synthesis. In this work, a novel deep eutectic solvent containing triethanolamine and sodium acetate was prepared and studied by Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), potential of hydrogen (pH), viscosity and conductivity. This deep eutectic solvent was applied for the synthesis of tetrahydrodipyrazolopyridines

a simple and new protocol was used to prepare large quantities of purified nano-ovalbumin from egg white. Nano-ovalbumin, as a retrievable and metal-free biocatalyst, was characterized by FT-IR, FESEM, XRD, MALDI-TOF and TGA/DTA. This biocatalyst displayed a high activity for green and efficient synthesis of tetrahydrodipyrazolo pyridines via multi-componentreaction of ethyl acetoacetate, hydrazine
