“…XRD characterization can also certify the successful preparation of M z @Bi x La y –NL. Figure S5 shows that typical peaks of Bi 2 O 3 and La 2 O 3 in both M z @Bi x La y –NL and Bi x La y –NL indicate the proper dispersion of Bi 2 O 3 or La 2 O 3 nanoparticles in both the NL matrix and coating. , …”

“…XRD characterization can also certify the successful preparation of M z @Bi x La y −NL. Figure S5 shows 32,33 The porosity of the composite was also determined, as shown in Table S2. The result suggested that the leather matrix exhibited a porosity of 63.6%, and the porosity decline after the fabrication of the composite (56.6 and 42.2% for Bi 3.48 La 3.48 − NL and Bi 28.2 @Bi 3.48 La 3.48 −NL, respectively.).…”

A high-shielding, low secondary radiation, lightweight, flexible, and wearable X-ray protection material was prepared by coimpregnating La 2 O 3 and Bi 2 O 3 nanoparticles in natural leather (NL) with an additional Bi 2 O 3 coating at the bottom surface of the leather. The prepared Bi 28.2 @Bi 3.48 La 3.48 −NL (28.2 and 3.48 mmol•cm −3 are the loading contents of elements) showed excellent X-ray shielding ability (65−100%) in a wide energy range of 20−120 keV with reduced scattered secondary radiation (30%). The bottom surface coating played a critical role in enhancing the X-ray attenuation and reducing the scattered secondary radiation by reflecting and deflecting incident X-ray photons. Excellent mechanical property with superb bending resistance of the NL matrix was properly maintained, and its tensile strength and tearing load were 15.39 MPa and 25.81 N•mm −1 , respectively. This lightweight and wearable high-performance protection material can facilitate safety and comfortability during intensive activities of practitioners in the health care industry.

“…According to these theories, the thin layer of grain boundary around the grains behaves like an insulating sheet, so the transfer of charge carriers at lower frequencies is not possible. However, high frequencies corresponding to high energy, so at high frequencies, the charge carriers gain enough energy and become able to overcome the barrier of insulating grain boundary and hence conduction becomes possible [63,64].…”

Herein, we used sol-gel auto combustion technique for fabrication of the series of nickel substituted magnesium-zinc spinel ferrite (Mg0.3NixZn0.7-xFe2O4) nanoparticles by varying nickel concentrations as 0.00 ≤ x ≤ 0.20. X-ray diffraction (XRD) investigation evidenced that the synthesized nanomaterials are of spinel ferrite nature with secondary phase. Moreover, the crystallite size was observed to be in the range from 13 to 17 nm as estimated by Scherrer’s formula. It has been found that the structural parameters (e.g., bulk density, lattice constant, micro strain, crystallite size, surface area etc.) of the as-synthesized magnesium-zinc spinel ferrite nanoparticles have been strongly influenced by doping content of nickel. Moving further, we have investigated the dielectric properties of the prepared nanoparticles in the frequency range from 20 Hz to 20 MHz. The remarkable electric modulus, impedance and dielectric properties of the prepared spinel ferrites made these materials a potential candidate for low- and high-frequency applications.
