Summary: In this study, tungsten oxide (WO3) nanoparticles were synthesized using a biological system, and the physico-chemical parameters were optimized to control the size of the nanoparticles. The results showed that pH and aeration rate were the most influential parameters, while temperature and time had less impact. The regression models and confirmation tests validated the consistency between the experimental values and predicted results. This study has practical significance in optimizing process parameters in industry or biological systems.

Summary: In this study, the installation parameters of deep mixing columns were optimized to achieve uniform mixing and reduce strength variability. DM columns were manufactured on clayey soils with different consistencies using a DM machine and slurry batch plant. The effects of various installation parameters on column strength and soil improvement ratio were investigated. The optimal installation parameters were determined as cement dosage of 325 kg/m(3), mixing blade rotation speed of 80 rpm, nozzle diameter of 3 mm, and soil liquidity index of 1.

Summary: In this research, nanostructured green pigments of ZnO and Co (CoxZn(1-x)O) were synthesized using impregnated layer combustion synthesis under microwave radiation. The Taguchi design of experiments was employed to investigate the influence of variables on the average crystallite size of particles, and it was found that the Co percentage and template type were the most important factors affecting the colorimetric properties of the final green product.

Summary: This study explores the optimal parameters for the weldability window of pure titanium and a new duplex stainless steel. By conducting experiments and simulations, the lower and left limits were determined based on physical quantities such as the jet, pressure, and melting. The findings suggest that the jet and left limit are related to the ratio of pressure and tensile strength.

Summary: This study designed an intercalation internal induction heating coil and drew a plate-type steel for the heating mold. The influence of special-shaped coils on induction heating effects was explored by simulating the temperature rise curve on the mold surface under different heating depths, currents, and frequencies. The Taguchi method and analysis of variance (ANOVA) were used to investigate the impact of these factors on maximum mean temperature and temperature uniformity. The synergistic effect of different factors on target results was analyzed using the response surface method (RSM).

Summary: The heat exchanger is a critical component in energy equipment. A split induction coil was designed for T-shaped aluminum pipe brazing, and the Taguchi method was combined with multi-physical simulation to optimize the split coil parameters. The results showed that the simulation model had high precision, and the optimal coil parameters were obtained. The induction brazing process was affected by skin effects and proximity effects, leading to high magnetic field intensity and high Joule heat generation around the joint.

Summary: The Taguchi optimization approach was used to determine the optimal mix ratios for geopolymer paste production using fly ash. The method enabled the exploration of the combined effect of process parameters on output response with minimal experiments, reducing time, cost, and effort. Sixteen mixtures were prepared and tested for compressive and splitting tensile strength, with the best parameter settings resulting in a compressive strength of 24.96 MPa and splitting tensile strength of 4.40 MPa. ANOVA analysis showed significant influences of standing time and NaOH concentration on the strength values.
