“…The significance of each term was decided according to the P ‐values. The terms with P ‐value less than .05 at the interval of 95% confidence indicate that the terms of the model are statistically significant and have significant effects on the dependent variable . The fact that the R 2 and R 2 adjusted values were close to each other indicated the compatibility of the model equation with the experimental results .…”

“…Various experimental design methods such as Central Composite, Box‐Behnken, and D‐optimal designs have been widely used in RSM . Among all the design of the experiment methods, the Box‐Behnken design (BBD) is more beneficial since it takes under consideration the interactions between the parameters including less experimentation .…”

The current research focuses on the findings of an investigation on optimizing of an electrospun antibacterial gelatin nanocomposite membrane for bone tissue engineering applications. For this reason, soluble starch coated silver nanoparticles (Ag‐NPs) and bioactive glass particles (BG) were incorporated in to gelatin (Gt) to fabricate Gt/Ag‐NPs/BG nanocomposite membranes. Employing Box‐Behnken design, second‐order models have been successfully obtained to evaluate the statistical significance of individual and interaction effects of applied voltage, tip‐to‐collector distance (TCD), and flow rate on fiber diameter. There was a reasonable agreement between the regression R2 value (0.9542), R2 predicted value (0.8768), and the R2 adjusted value (0.9286) across the entire factor space with identical observations for the experimental and model values. Under optimum conditions (applied voltage of 26 kV, TCD of 180 mm, and flow rate of 0.5 mL/h), the nanocomposite membrane with similar fiber size of bone tissue extracellular matrix can be fabricated with the predicted value of 557 nm obtained by the proposed model. The optimized nanofiber membrane was fabricated under these conditions and average fiber diameter of this membrane was found as 472 ± 94 nm. The characterization studies of this nanofiber suggest that obtained nanocomposite is a potential candidate for bone tissue engineering applications.

“…Although, the extraction yield using SLM process is lower compare to the reactive liquid extraction process [30], SLM process had advantage in term of single operation step compare to reactive liquid extraction method. Another variation of liquid membrane, which is bulk liquid membrane (BLM) showed higher LA extraction yield than the SLM process using in this study [31]. However, BLM requires a large amount of organic liquid membrane compared to SLM and will increase the overall separation cost [32].…”

Supported liquid membrane (SLM) is the most effective technique to extract and recover the desired product from the biomass products in a single step. The study of the operation parameters in SLM system is very important to improve the yield of extraction and recovery of the product. In this study, different types of stripping agents such as sodium hydroxide (NaOH), sodium carbonate, hydrochloric acid, trimethylamine, and water were tested in the SLM system to extract levulinic acid (LA). By using 0.3 M trioctylamine in 2-ethyl-1-hexanol as liquid membrane phase, it was found that NaOH was the best stripping agent to extract LA. The concentration of the NaOH stripping agent was varied from 0.25 M to 1 M. The best stripping agent concentration was 0.5 M, which gave an LA extraction of 86% from a 10 g/L LA aqueous solution. The flow rate of the feed and stripping phase was investigated from 25 mL/min to 125 mL/min. SLM operated at 75 L/min was found to be adequate in reducing the boundary layer thickness at both sides of the SLM phases without any leakage of the liquid membrane and breakage of the matrix support. At the best stripping condition, 89% of the LA was extracted using 0.5 M NaOH that operated at flow rate of 75 mL/min.
