A factorial design with 12 mix formulations was used to evaluate the individual and combined effects of GD and MP on physical, mechanical, and durability properties. The results show that GD incorporation leads to improved matrix compactness, as evidenced by reduced water absorption (up to 66% at 15% replacement) and porosity (over 50% reduction). MP contributes additional improvements in density and strength. Based on macroscopic property correlations and established literature, these improvements are attributed to enhanced particle packing and the filler effect of the waste materials.

By utilizing concentrated sulfuric acid, simultaneous carbonization and surface functionalization were achieved under mild conditions, eliminating the need for high-temperature pyrolysis. Comprehensive physicochemical characterization revealed a highly porous carbonaceous framework enriched with sulfonic acid groups, yielding a fine-grained adsorbent (<20 μm) with high thermal stability and a carbon content of approximately 85 wt%. Batch adsorption experiments were systematically performed to evaluate the effects of adsorbent dosage, solution pH, initial dye concentration, contact time, and temperature. The adsorption process exhibited high removal efficiency (>90%) at the natural pH of the dye solution, eliminating the need for pH adjustment. Kinetic analysis demonstrated that the adsorption behavior followed a pseudo-second-order model, indicating that chemisorption governs the rate-controlling step, with an activation energy of 9.01 kJ/mol. Equilibrium data were best described by the Langmuir isotherm, confirming monolayer adsorption on a homogeneous surface, with a maximum adsorption capacity of 2.70 mmol/g at 55°C. Thermodynamic parameters (Δ<i>H</i>° = +9.301 kJ/mol and negative Δ<i>G</i>° values) indicated that the adsorption process is endothermic and spontaneous.

In this context, the adoption of alternative fuels has gained significant attention as a potential strategy to improve combustion characteristics. Biofuels, including biodiesel and alcohol-diesel blends derived from both edible and non-edible feedstocks, serve as viable alternatives to fossil fuels due to their inherent oxygen content and enhanced combustion characteristics. This review systematically analyzes peer-reviewed experimental studies from the past two decades to assess cyclic combustion variability in diesel engines powered by biofuel-diesel blends, focusing on in-cylinder pressure dynamics, indicated mean effective pressure (IMEP), pressure rise rate, and heat release characteristics, and comparing statistical and wavelet-spectrum-based diagnostic methodologies. Conventional statistical metrics, including the coefficient of variation (COV) and correlation-based measures, primarily assess the overall magnitude of fluctuations but offer limited insight into the temporal evolution and predominant modes of cyclic combustion variability, which can be more effectively analyzed using advanced time-frequency methods.
