Machine Learning Assisted Sustainable Biochar-Reinforced Epoxy Nanocomposites for Improved Dielectric Performance Meenu Khan, Sanketsinh Thakor, Unnati A. Joshi, Prince Jain, Mahendra Singh Rathore, Anand Joshi, Chandan R. Vaja Journal of Macromolecular Science Part B Physics, 2026 This paper provides a green and analytical design for improving the dielectric performance of epoxy-based composites through biochar from rice husk and by hybridizing with Fe3O4 nanoparticles. Biochar from rice husk was produced through pyrolysis to 500 °C and resulted in a carbon-based porous material characterized by microscopic, structural and elemental analysis (SEM, XRD, EDX). The epoxy composites were prepared with biochar and biochar-Fe3O4 fillers, and with 1, 2 and 3 wt.% loadings. The dielectric performance with 2 wt.% loading, specifically in hybrid, form had the best dielectric performance and included significant increases in dielectric constant and AC conductivity due to interfacial polarization and charge migration. Further analysis was provided through the electric modulus method that scrutinized the dielectric loss and gave consistent responses for relaxation. Prediction of the real (ε′) and imaginary parts (ε″) of permittivity was achieved through ensemble learning models with a high degree of accuracy (R2 > 0.99) and demonstrated the use of predictive analytics for materials research. The outcome discussed here provides evidence that endorsement of these biochar-based fillers, along with computational methods, could encourage sustainable and successful usages of advanced materials in electronics, energy stores and EMI shielding.
The effect of synthesis techniques on the gas sensing properties of TiO2/SiC/CoFe2O4 nanocomposites as gas sensor Meenu Khan, Lubna Aamir, Deepshikha Rathore, H. S. Albaqawi, A. A. M. Othman, Supratim Mitra Applied Physics Letters, 2024 This study investigates the impact of two distinct methodologies on the structural, morphological, and gas sensing properties of TiO2/SiC/CoFe2O4 (TSC) nanocomposites determined using x-ray diffraction (XRD), scanning electron microscopy (SEM), LCR meter, and gas sensing unit respectively. The TiO2/SiC/CoFe2O4 nanocomposites were synthesized using chemical co-precipitation method (C-TSC) and the solid state method (G-TSC). The Scherrer formula was used to calculate the average grain size of C-TSC and G-TSC, which was estimated to be 8 ± 2 nm and 10 ± 2 nm, respectively. The formation of TSC nanocomposites was confirmed by XRD, SEM, and EDX analysis. The response (%) toward ethanol and NH3 gas was tested as a function of flow rate (ppm) and temperature from room temperature (28 °C) to 300 °C. The response (%) was observed to be increasing with increasing temperature and three intermediate temperatures were found. The response and recovery time were also measured with varying gas concentrations. The long-term stability of devices was tested up to 30 days and less variation in result was found, which confirms stability of sensor. The material synthesized using chemical co-precipitation method (C-TSC) shows better properties than G-TSC.
