The three series were synthetically prepared using the conventional solid-state process. X-ray diffraction (XRD) combined with Rietveld refinement, confirm the magnetoplumbite structure, alongside a secondary phase with space group R-3 m. The hexaplate-like grain sizes varied in the range of 2.37–1.9 µm, while the crystallite sizes are in the range of 119–104 nm. The FTIR spectra revealed two positions at 573 cm⁻¹ and 494 cm⁻¹ corresponding to the tetrahedral and octahedral sites, respectively, which confirmed the M-type hexagonal structure. The direct optical band gap energy (E_g) of BCFMO increases from 2.91 eV to 3.14 eV with varying Mg²⁺ concentration from 0.3 to 0.5. The presence of Fe in the + 3 oxidation state (Fe³⁺) and of Mg²⁺ is confirmed by XPS. The saturation magnetization M_s decreases from 111.18 to 72.34 emu/g which attributed to the addition of Mg²⁺ in Fe³⁺ in 12 k octahedral site and confirmed by DRX and XPS analyses. The increase of the coercivity H_C from 3.17 kOe to 5.81 kOe is due to the reduction in crystallite sizes. The anisotropy field H_a and the effective anisotropy constant K_eff rise from 12.13 to 21.78 kOe and 6.74 to 7.88 (10⁵emu/cm) for x = 0.3 to 0.5, respectively. The Para-Ferromagnetic phase transition at Curie Temperature T_C was identified for all compounds. The substitution by Mg²⁺ leads to a reduction of T_C from 730 to 693 K. The maximum entropy (− ΔS_m^max) decreases from 1.68 to 1.29 J/kg.K, while, the relative cooling power (RCP^max) increases from 110.58 J/kg to 217.9 J/kg for x = 0.3 to 0.5, respectively at µ₀H = 5 T.

The nanocomposite, known as CMC-g-poly(AM-co-ITA)/Clay, was synthesized using potassium persulfate (KPS) as the initiator and N, N′-methylene bisacrylamide (MBA) as the cross-linker. The goal was to create nano adsorbents with excellent adsorption capacity, easy separation, selectivity, and superior reusability for eliminating dyes from aqueous solutions. The nanocomposite’s structure was analyzed using various techniques including FTIR, XRD, HRTEM, FESEM, TGA, and BET. The study of the nanocomposite’s thermal stability revealed that the one with 15% clay exhibited the best thermal stability. FESEM images showed a high cross-linking density and a porous surface, facilitating water diffusion and affecting the swelling behavior. The nanocomposites’ gel content and swelling behavior were compared with those of a hydrogel without clay when placed in water. The results indicated that as the clay content increased, the swelling ratio decreased while the gel content increased. The CMC-g-poly (AM-co-ITA)/Clay nanocomposite was found to have high stability in an aqueous solution and a negatively charged surface at a pH higher than 3.1. The findings indicated that adding clay to the hydrogel improved its ability to remove Brilliant Green from water. Introducing 15% clay into the hydrogel raised its maximum adsorption capacity for BG dye removal from 199.67 to 1513.55 mg/g. Various models were used to analyze the experimental results, with the pseudo-second-order demonstrating the best fit for the kinetic model. Equilibrium data were assessed using Langmuir, Freundlich, and Temkin isotherm models.

CEPPM-MH and ammonium polyphosphate (APP) were synergistically introduced into the epoxy thermosets to improve the fire resistance of the composites. For the S7 composite samples that contained 10% of APP and 10% of CEPPM-MH, the LOI was increased to 30.1.

In addition, the flexural strength and flexural modulus were found to be improved by 76.8% and 45.1%, respectively, in the flexural performance test. Furthermore, the organic–inorganic hybrid curing agent, which was prepared by modifying the magnesium hydroxide with water as the only solvent, could be introduced into epoxy resins as both curing agent and flame retardant, which not only effectively reduced the fire risk but also improved the comprehensive performance of the materials.

Based on the analysis of magneto-electronic properties, it is observed that Li₂Zr₆MnCl₁₅ demonstrates a semiconductor (2.2 eV Up/0.55 Dn) behaviour with a magnetic moment of 4.00 µ_B. Comprehensive analysis of optical properties involved intricate calculations of various parameters related to the behaviour of light, such as dielectric constants, refractive indices, reflectivity, extinction coefficients, electron energy loss, absorption coefficients, and optical conductivity functions up to 14.0 eV. The research was carried out in the temperature range of 50 to 800 K to determine the Seebeck coefficient, electrical conductivity, thermal conductivity, power factor (PF), Hall coefficient, and figure of merit for the investigated material, which showed great promise for use in thermoelectric devices, with PFs of about 7.5 × 10⁴ W/K²ms, respectively.

The research indicates that the G_MAC and G_LAC values for Li₂Zr₆MnCl₁₅ fall as the photon energy rises, with a noteworthy increase near K-edge absorption owing to the photoelectric effect dominance at low energy. Both Z_eff and N_eff declined as the photon energy increased, with Z_eff reducing from 25.56 to 25.27 and N_eff decreasing from 3.22 × 10²³ to 3.18 × 10²³ electrons/g.
