“…Box-Behnken design is a rotatable quadratic design [ 51 , 67 ] where the highest or lowest levels of all factor formulations do not appear simultaneously [ 68 ], the trials combinations being placed at the mid-points of each edge and at the center of the cube [ 51 ]. Thus, the number of experiments is reduced from 27 (corresponding to the full factorial design) to 13, summarized in Table 2 .…”

The aim of this study was the development and optimization of some topical collagen-dextran sponges with flufenamic acid, designed to be potential dressings for burn wounds healing. The sponges were obtained by lyophilization of hydrogels based on type I fibrillar collagen gel extracted from calf hide, dextran and flufenamic acid, crosslinked and un-crosslinked, and designed according to a 3-factor, 3-level Box-Behnken experimental design. The sponges showed good fluid uptake ability quantified by a high swelling ratio. The flufenamic acid release profiles from sponges presented two stages—burst effect resulting in a rapid inflammation reduction, and gradual delivery ensuring the anti-inflammatory effect over a longer burn healing period. The resistance to enzymatic degradation was monitored through a weight loss parameter. The optimization of the sponge formulations was performed based on an experimental design technique combined with response surface methodology, followed by the Taguchi approach to select those formulations that are the least affected by the noise factors. The treatment of experimentally induced burns on animals with selected sponges accelerated the wound healing process and promoted a faster regeneration of the affected epithelial tissues compared to the control group. The results generated by the complex sponge characterization indicate that these formulations could be successfully used for burn dressing applications.

“…In the present study, the Box–Behnken design was used to obtain a proper model for the optimization of the removal efficiency with four process variables (temperature, pH, initial concentration and contact time) at three levels. All experiments were conducted in triplicate to verify the precision for the removal of Pb(II) ions by nZVI/rGO composites [ 40 ]. Table 2 shows the value of the dependent and independent variables as well as the actual and predicted data for removal efficiency of every experiment, and a good agreement existed between the predicted results and those obtained from the experiments.…”

Reduced graphene oxide-supported nanoscale zero-valent iron (nZVI/rGO) composites were prepared by chemical deposition method and were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, N2-sorption and X-ray photoelectron spectroscopy (XPS). Operating parameters for the removal process of Pb(II) ions, such as temperature (20–40 °C), pH (3–5), initial concentration (400–600 mg/L) and contact time (20–60 min), were optimized using a quadratic model. The coefficient of determination (R2 > 0.99) obtained for the mathematical model indicates a high correlation between the experimental and predicted values. The optimal temperature, pH, initial concentration and contact time for Pb(II) ions removal in the present experiment were 21.30 °C, 5.00, 400.00 mg/L and 60.00 min, respectively. In addition, the Pb(II) removal by nZVI/rGO composites was quantitatively evaluated by using adsorption isotherms, such as Langmuir and Freundlich isotherm models, of which Langmuir isotherm gave a better correlation, and the calculated maximum adsorption capacity was 910 mg/g. The removal process of Pb(II) ions could be completed within 50 min, which was well described by the pseudo-second order kinetic model. Therefore, the nZVI/rGO composites are suitable as efficient materials for the advanced treatment of Pb(II)-containing wastewater.

“…In the present study, the D-optimal form of RSM was used for optimizing the parameters. To evaluate the influence of the reaction parameters on the decolorization, three main factors were selected: (a) reaction time (b) dosage (c) pH, a total of 20 experiments were introduced with Design Expert 7.0.0 [14].…”

Quickly developing industrialization is one of the significant benefactors of natural contamination as it presents awful difficulties for the earth and the ordinary citizens. Biological synthesis of the silver nanoparticles (AgNPs) atthe presence of the aqueous leaf extract of Celosia argentea, funtioned as the reducing and capping agent. In this research study, we are reportthe synthesis of the AgNPs with the optimized experimental parameters at the pH. Formation of the AgNPs was confirmed by the UV-Visible spectroscopy and FT-IR analysis. The structural characterization was carried using the SEM-EDX, providing the size of the nanoparticles to be 50-80 nm. The AFM showed the spherical surface topology, the zeta potential whereas, particle size analysis showed stability and the average size was determined to be 50 nm.
