In particular, the temperature dependence of specific heat have been investigated for various dimerization parameter and magnetic field strength in the model Hamiltonian. Using a hard core bosonic representation, the behaviors of thermodynamic properties have been studied by means of excitation spectrum of mapped bosonic gas. The effect of dimerization parameter, as the ratio between two types of exchange constants, on thermodynamic properties has also been studied via the bosonic model by Green’s function approach. Furthermore we have studied the magnetic field dependence of specific heat and magnetization for various dimerization parameters. At low temperatures, the specific heat is found to be monotonically increasing with temperature for magnetic fields in the gapped field induced phase region. We have found the magnetic field dependence of specific heat shows a monotonic decreasing behavior for various dimerization parameter due to increase of energy gap in the excitation spectrum.

Composite samples were prepared using a hot hydraulic press technique, and their thermal stability was analyzed through thermal gravitational analysis in a nitrogen environment. The results indicate that the cellulose-CNF composite exhibits a simplified single-stage decomposition compared to the more complex behavior observed in pure cellulose. FTIR analysis reveals the presence of –OH bonds, indicating enhanced hydrophilic properties in the composite. Dielectric spectroscopy, conducted over a frequency range of 100 Hz to 1 MHz, explores the effects of CNFs on the relaxation and conduction mechanisms at different temperatures. Parameters such as dielectric permittivity, AC conductivity, electrical modulus, and complex impedance were studied, incorporating Jonscher’s equation, and the Havriliak–Negami model. The interplay between interfacial charge and cellulose crystallinity emerged as a crucial factor in the observed dielectric behavior.
