Calcium nitrate trihydrate

All chemicals and reagents, namely calcium nitrate trihydrate (99 %), nickel nitrate hexahydrate (99 %), iron nitrate nonahydrate (99 %), tetraethyl orthosilicate, glucose, barbituric acid, 1‐naphthylamine and the respective benzaldehyde derivatives, were purchased from Merck Chemical Company. ¹H NMR spectra were taken with 400 MHz NMR spectrometer for solution NMR analysis. IR spectra were obtained with Shimadzu's instrument. Electrothermal Programmable Digital Melting Point Apparatus used to measure melting points. BGMN/Profex/AutoQuan software reported the results of the X‐Ray Diffraction study. nanoparticles were examined using a field emission scanning electron microscope (FE‐SEM), On the Zeiss, that ran at an accelerating voltage of 15 kV. The magnetic properties of nanostructure were measured by a vibrating sample magnetometer (VSM) with PPMS‐9 T at 300 K. The Brunauer‐Emmett‐Teller (BET) specific area and pore volume were measured via the nitrogen adsorption/desorption isotherms method using BELSORP MINI II. High Resolution Transmission Electron Microscopy (HR‐TEM) was prepared by a FEI TECNAI F20 at 200 kV instrument.
