*2.4. Analytical Techniques*

It is worth mentioning that, in addition to the data generated on di fferences in the bonding mechanism of the pure and blended samples of NSP and PSP used in this study, the quality of the pellets was interpreted in terms of strength and combustion e fficiency. The study did not incorporate the use of special tools that are restricted to the determination of the quality parameters; instead, the study relied on evidence of the above quality parameters from the data obtained through the use of state-of-the-art molecular, microscopic, and thermal analytical instruments. Therefore, the subsections below present specific information about the analytical instruments used in this study and describe the experimental procedures related to how the instruments were used. For the sake of reproducibility, all analyses presented in this study were repeated in triplicate, and average values were reported.
