Herein, we prepared new nanocomposites from polyaniline (PANI) as a conductive polymer, and ferrites, MFe2O4 (M = Co2+, Cu2+, Mg2+, Ni2+, and Zn2+), as metal-oxide ceramics using sucrose sol-gel auto-combustion and in-situ of polymerization. The prepared nanocomposites’ structural, thermal, magnetic, and electrical/dielectric characteristics were investigated. X-ray diffraction (XRD) revealed the formation of the metal-oxide ceramics with weak crystallinity due to their coating in the amorphous structure of the PANI matrix. Transmission electron microscopy (TEM) images exhibited the wrapping of the entire metal-oxide ceramic particles by the PANI matrix, thus confirming the core-shell structure formation. Vibrating sample magnetometer (VSM) results showed drastic reductions in all ferrites’ magnetization by their inclusion in the non-magnetic PANI matrix. The measured coercivity values showed a noticeable lowering in the presence of PANI. Besides, the thermogravimetric analysis (TG) technique indicated apparent increases in the thermal stability of the prepared nanocomposites compared to the pure PANI. Moreover, the electrical conductivity results indicated a change from metallic-like behavior for the pure PANI to the semiconductor by including the ferrites. Furthermore, by comparing the pure PANI, the dielectric properties of nanocomposites increased by the presence of ferrites, suggesting the suitability of the entire nanocomposites to be used in the energy storage devices such as capacitors.

“…The methods used for analysis are Scherrer's, Williamson-Hall, Size-Strain, and Halder-Wagner. [17][18][19][20][21][22] We will discuss the inaccuracy of these methods in calculating parameters, particularly the crystallite size and induced strain. We would suggest more accurate method for calculating these parameters which will overcome the issue with Scherrer's method and Modified Scherrer's method.…”

Li(x)Ni(1-x)O (x = 0.01, 0.02 and 0.03) samples were synthesized via sol-gel process. Fourier transform infrared spectroscopy (FTIR) confirms the formation of Li(x)Ni(1-x)O (x = 0.01, 0.02 and 0.03) series. Powder X-ray diffraction technique was used for the analysis of crystallite properties. The mean crystallite size using Scherrer’s Method has been found to be 21.66 nm, 20.09 nm and 19.25 nm for Li(x)Ni(1-x)O (0.01, 0.02 and 0.03) respectively, which is a rough estimate. To inspect the impact of strain induced in Li(x)Ni(1-x)O further analysis has been done. Willamson Hall Plot-Uniform Deformation Model (WH-UDM), Size-Strain (SSP) and Halder-Wagner Plot (H-W) Models were applied to determine physical and microstructural parameters i.e. crystallite size and lattice strain of Li(x)Ni(1-x)O (x = 1%, 2% and 3%) using X-ray powder diffraction analysis. The morphology of Li(x)Ni(1-x)O (x = 1%, 2% and 3%) has been analyzed by High-Resolution Transmission Electron Microscope (HRTEM). The outcomes of estimated mean crystallite size determined by Scherrer’s Method, WH-UDM Plot, SSP and W-H models were compared with morphologically investigated crystallite size via TEM analysis.
