“…However, this approach cannot ensure optimum conditions due to a lack of evaluating of other factors in their suitable range [51]. Basically, Taguchi method is a considerable approach to remove these obstacles in experiment design [52]. Therefore, similar to our previous studies, Taguchi method was used for achieving optimum conditions based on the selection of three parameters (incubation times, CuSO 4 and glucose concentrations) [25,33,53].…”

In nanotechnology, using of metallic nanoparticles (MNPs) has obtained major attention for over a century because of their unique properties in nano scale. In this paper, the effect of three factors (incubation time, concentrations of copper sulfate and glucose) on the biosynthesis of copper (II) oxide nanoparticles (CuO NPs) by Halomonas elongata IBRC-M 10214 and the antibacterial activity of nanoparticles were evaluated. Experiment design and analysis of Taguchi method were carried out by Qualitek-4 software. Effect of CuSO4 concentration (1.4, 2.8 and 5.6 mM), incubation time (48, 72 and 96 h) as three different levels was measured as three major factors in the biosynthesis of metallic nanoparticles. Synthesized CuO nanoparticles were characterized by utilizing ultraviolet-visible (UVVis) spectroscopy, X-ray diffraction (XRD), Fourier transform infra-red (FT-IR) spectroscopy and field emission scanning electron microscope (FESEM) techniques. Among the three factors, results illustrated that considerable effect was related to CuSO 4 concentration. These analyses demonstrated that the average CuO nanoparticles crystalline size was 57-79 nm with rectangular shape. Also, for evaluating of antibacterial effects, maximum zone of inhibition, two important multidrug resistant pathogenesis bacteria, Escherichia coli ATCC 25922, and Staphylococcus aureus ATCC 43300 were used. Antibacterial assay of CuO nanoparticles showed antibacterial activity toward the pathogenic bacterial strains of E. coli by 5 mm and S. aureus by 5.5 mm for maximum zone of inhibition. In conclusion, this study presented simple, low expensive, eco-friendly and high productivity in the fabrication of CuO nanoparticles. In addition, these metallic nanoparticles had antibacterial effect that could be usable in medicinal aspect for fighting against prominent pathogen bacteria such as E. coli ATCC 25922 and S. aureus ATCC 43300.

Recovery of recycled acrylonitrile-butadiene-styrene (ABS) through mixing with styrene-ethylene/butylene-styrene (SEBS) has been studied in this paper. To simulate recycled ABS, virgin ABS was processed through 5 cycles, at extreme processing temperatures, 220 ºC and 260 ºC. The virgin ABS, the virgin SEBS, the recycled ABS and the mixtures were mechanically, thermally and rheologically characterized after the various cycles of reprocessing in order to evaluate their corresponding properties and correlate them with the number of cycles undergone. With these data and using CAE (Computer Aided Engineering) the injection process was simulated by obtaining the optimal injection process parameters. Mixtures were injected at two temperatures in a sensorised mold correlating the shrinkage of the parts with temperature.The results show that tensile strength of ABS remains practically constant as the number of reprocessing cycles increases, while in the material injected with SEBS the tensile strength decreases. Concerning the Charpy notched impact strength; the values of the ABS reprocessed at 220 ºC remain more or less unchanged, while the values for 260 ºC show a significant decrease. The adhesion of the SEBS causes, in both cases, an increase in impact strength. DSC techniques enabled us to observe how the glass transition temperature (T g ) remains more or less constant regardless of the number of cycles or the temperature, whereas the crosslinking is much greater in the samples reprocessed at 260 ºC.Finally, the viscosity decreases with each cycle and this decrease becomes even more noticeable with the addition of SEBS, and also that the parts molded at lower temperatures have less shrinkage.

“…The above Table highlights the importance of selection of parameters and the significance of their optimum levels to achieve a robust process or parameter design [1][2][3][4][5][6][7][8][9]. The parameters like screw stroke, injection temperature have been found out less important and nozzle temperature has been substituted for barrel temperature.…”
