This study comprehensively investigates the materials' structural and electrical properties, including X-ray diffraction (XRD), UV absorption, thermal characteristics, and both AC and DC conductivity behaviors. The absorbance spectra were meticulously recorded with a UV–Vis spectrometer across the 200 nm–900 nm wavelength range, revealing band gap energies between 2.0090 eV and 2.2832 eV. Our thermoelectric power analysis demonstrated compelling evidence of the Seebeck coefficient (S) and carrier concentration (ƞ) across varying temperatures, from room temperature up to the Curie temperature. Notably, all doped and undoped samples exhibited negative Seebeck coefficients, firmly establishing their N-type semiconducting behavior. The Seebeck coefficients ranged from −2.023 μV/K to −15.821 μV/K, with carrier concentrations varying from 7.124 × 10²² m⁻³ to 8.360 × 10²² m⁻³, and the Curie temperature fluctuated between 493 K and 593 K. Furthermore, we calculated the DC resistivity of the MCSF compounds as a function of their dopant levels (ranging from MCSF-0 to MCSF-5) over a temperature spectrum of 300 K–750 K. The findings revealed that the DC dielectric resistivity of these compounds spans from 9.042 × 10⁴ Ω m to an impressive 1.563 × 10⁵ Ω m. Activation energy values were determined to fluctuate between 0.5655 eV and 0.7820 eV. Interestingly, the Curie temperature initially decreased with increasing Sm³⁺ substitution, then rebounded, ranging from 511 K to 559 K. In addition, we meticulously documented the AC conductivity (σ_a<em>c</em>) and log(σ_a<em>c</em>) values at an 8 MHz frequency, utilizing an LCR meter throughout the frequency range of 4 Hz–8 MHz. The observed log(σ_a<em>c</em>) values varied from −2.0724 to −2.9437. As the dopant concentration increased, there was an initial rise followed by a decline in log(σ_a<em>c</em>), with the highest level of doping (MCSF-5) demonstrating exceptional conductivity. Finally, the dielectric loss tangent (tan δ) was found to range between 0.0874 and 0.3099, providing additional insights into the material's performance characteristics.

Due to LDH's layered structure, anion-exchange capacity, and synergistic interaction with CB, the composites were used to enhance the adsorption efficiency for Dox. The composites were produced using two different amounts CB (5 g and 2.5 g) with MgAL-LDH and various analyses such as SEM, FT-IR, XRD and BET/N₂ were used to characterize the resulting samples. Adsorption key parameters including adsorbent dosage, solution pH, contact time, initial concentration and temperature were investigated for doxycycline. The adsorption characters for CB conformed to Langmuir isotherm (R² = 0.99), while Dox adsorption for LDH (R² = 0.95), 2.5CB@LDH (R² = 0.97) and 5CB@LDH (R² = 0.99) fitted Freundlich isotherm.
