TL;DR: In this article, the authors have made Mossbauer and magnetic studies of Cu 2+ substitution effect in CoFe 2− x O 4 Ferrites (0.0, 0.1, 0., 0.2, 0.3, 0, 4, and 0.5), showing a reduction in saturation magnetization and an increase in coercitivity with Cu 2 + ion substitution.

TL;DR: In this article, cation distribution, magnetic, and hyperfine interaction studies of Cu2+-substituted mixed Ni-Zn nano-spinel ferrites prepared by combustion technique are reported.

TL;DR: In this article, a typical as-prepared sample was characterized by using TGA DTA and then the asprepared samples were annealed at 600°C for 6h in air atmosphere and used for further characterizations.

TL;DR: In this paper, silver doped Mg-Mn ferrite nanoparticles (Mg1-yMnyAgxFeFe2-xO4) are synthesized by using sol-gel technique and are characterized by X-ray diffraction (XRD), energy dispersive x-ray (EDX) analysis, field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM) and Mossbauer spectrography.

TL;DR: The fabricated biosensor was successfully employed for determination of uric acid in human serum and urine and lost only 15 % of its initial activity over a period of 7 months, when stored at 4 °C.
