“…The model for Y 2 has a par-ticularly good fit. The statistical validity of the developed models is confirmed by cal-culating the coefficients of variation (CV), with lower values indicating more signifi-cant models [ 31 ]. As shown in Table 3 , the CV for both models is low (22.75% and 1.15%, respectively), indicating the accuracy of the experimental results.…”

In order to remove and reuse the ecotoxic dye Eriochrome black T (EBT) from dyeing wastewater, we used a process called cetyltrimethylammonium bromide (CTAB)-assisted foam fractionation. By optimizing this process with response surface methodology, we achieved an enrichment ratio of 110.3 ± 3.8 and a recovery rate of 99.1 ± 0.3%. Next, we prepared composite particles by adding β-cyclodextrin (β-CD) to the foamate obtained through foam fractionation. These particles had an average diameter of 80.9 μm, an irregular shape, and a specific surface area of 0.15 m2/g. Using these β-CD-CTAB-EBT particles, we were able to effectively remove trace amounts of Cu2+ ions (4 mg/L) from the wastewater. The adsorption of these ions followed pseudo-second-order kinetics and Langmuir isotherm models, and the maximal adsorption capacities at different temperatures were 141.4 mg/g at 298.15 K, 143.1 mg/g at 308.15 K, and 144.5 mg/g at 318.15 K. Thermodynamic analysis showed that the mechanism of Cu2+ removal via β-CD-CTAB-EBT was spontaneous and endothermic physisorption. Under the optimized conditions, we achieved a removal ratio of 95.3 ± 3.0% for Cu2+ ions, and the adsorption capacity remained at 78.3% after four reuse cycles. Overall, these results demonstrate the potential of β-CD-CTAB-EBT particles for the recovery and reuse of EBT in dyeing wastewater.

“…The response surface methodology (RSM) was applied to optimize outcomes for flexural characteristics. [ 31,32 ] The weight % of silica A, B, and Roselle were the three parameters with different ranges with polyurethane as a polymeric material. The response surface methodology exhibits the optimum weight % of silica A, B, and Roselle with 0.78%, 1%, and 2%, respectively.…”

Fiber‐reinforced composites have found their prominent place in various applications, including aerospace, automobile and marine manufacturing industries, because of outstanding properties obtained during composite preparation. One such aspect of improving the composite property is hybridization, where natural fibers (or both natural and synthetic fibers) are combined to obtain different composite structures for diverse applications. This research aims to hybridize the composite considering Kenaf fabric and Kevlar fabric reinforced in an unsaturated polyester matrix with different proportions. Three different laminate sequences (L1, L2, and L3) were developed by considering the fabric's stacking sequence, weave pattern, and orientation. The composite laminates prepared were tested where Taguchi's method (L9 orthogonal array) and artificial neural network were used to study influencing parameters for tribological behavior of the composite. From the practical information, a prediction model from the artificial neural network is applied to forecast the wear rate of the laminates at a broader range of operating factors beyond and within the test phase. The microstructures of the worn surfaces were investigated from a scanning electron microscope to confirm the wear principle of the laminates under different cases.

“…Electrical discharges have been established to affect the surface integrity of work pieces for many years [12,13]. Several studies have shown that the roughness of the surface of wire-EDM varies with the duration of the current pulse (T on ) [14][15][16], the peak discharge current (I p ) [17][18][19][20], and the average energy per spark [21,22]. Using a Response Surface Methodology (RSM), a mathematical model was proposed in order to evaluate the WEDM process parameters during the machining of Inconel 627 alloy [23].…”

Inconel 718 alloy has a wide range of applications in the aerospace sector because of its superior mechanical properties and its weldability. The machining of such higher strength materials with complex shapes is possible with wire electrical discharge machining. In the present research, an endeavor was made to enhance the machining process by utilizing zinc-diffused coating brass wire electrode and Taguchi-Data Envelopment Analysis-based Ranking (DEAR) methodology in the process while machining Inconel 718 alloy. Material removal rate, kerf width, and surface roughness were considered as the quality measures. The optimal arrangement of input factors in the Wire Electrical Discharge Machining (WEDM) process were found as 140 µs (Ton), 50 µs (Toff), 60 V (SV), and 5 kg (WT) among the elected factors with the error accuracy of 1.1%. The pulse-off time has the most significance on formulating the quality measures owing to its importance on deionization in the process.
