Summary: Nanofluids are considered an attractive solution for sustainable machining of difficult-to-cut materials. This study examines the effects of various preparation factors on nanofluid characteristics, emphasizing the role of aggregate morphology on viscosity and proposing a novel mechanism for nanoparticles' influence on wettability based on nanolayering theory. The multi-objective optimization analysis suggests that moderate MWCNT concentration, high sonication time, and low surfactant amount are optimal within the search domain.

Summary: The experimental investigation on the viscosity of nanofluids with Fe3O4 nanoparticles and carbon nanotubes (CNTs) showed new empirical formulas for accurate viscosity predictions. Surfactants like TMAH, SDS, and SLS were found to improve stability, reduce viscosity, and enhance thermal conductivity in Fe3O4-water, CNT-water, and Fe3O4-CNT-water nanofluids. The CNT-water and Fe3O4-CNT-water nanofluids exhibited shear-thinning behavior, while water-based Colace-Fe3O4, TMAH-Fe3O4, and TSC-Fe3O4 nanofluids displayed linear rheological behavior.

Summary: This study examined the effect of an external magnetic field on the heat transfer characteristics of magnetic nanofluids (MNFs). MNFs were prepared by synthesizing Fe3O4 nanoparticles with mass ratios of 0.5%, 1%, and 2% in deionized water. The thermal conductivity and viscosity, which directly influence heat transfer, were measured after ensuring the stability of the MNFs. A unique experimental setup was used to investigate the effects of magnetic fields on different MNFs using a rotating magnetic field. The heat transfer experiments showed that the average Nusselt numbers increased by 25%, 38%, and 60% for MNFs with mass ratios of 0.5%, 1%, and 2% under the influence of a constant magnetic field, compared to deionized water.

Summary: The main theme of this study is to investigate the influence of ultrasonication time on the colloidal stability and thermal conductivity of multi-walled carbon nanotubes-Therminol 55 based nanofluid. The results show that an increase in ultrasonication time up to 120 min enhances the colloidal stability of the nanofluid samples, but prolonging the time weakens the stability. The thermal conductivity of the nanofluid is affected by both temperature and MWCNT concentration, and increasing the ultrasonication time significantly improves the thermal conductivity.

Summary: In this study, the stability, thermal conductivity, and viscosity of MXene/water nanofluids were systematically investigated, and thermophysical prediction models were developed. It was found that adding anhydrous sodium citrate and prolonging ultrasonication time to 60 min significantly improved the stability. The thermal conductivity of 0.1 wt% freshly prepared nanofluid increased by 27.41% at a temperature of 60 degrees C compared to water. Surprisingly, the viscosity remained almost constant over the range of 0-0.1 wt%. Artificial neural network models showed a satisfactory agreement between predicted and experimental values for thermal conductivity and viscosity, with relative errors within ±1.5% and ±5% respectively. This study is expected to contribute to the advancement of nanofluids.

Summary: Mobile robots are automatic vehicles with wheels that can be moved automatically. They are controlled by PID controllers, where kinematic modeling is used to design appropriate robots. The PID controller adjusts the motor speed based on the proportional, integral, and derivative gains. To avoid variations in robot speed due to changes in direction, the Social Spider Optimization (SSO) algorithm is utilized. This paper aims to demonstrate the effectiveness of the proposed approach in achieving precise speed control of the robot, even in the presence of disturbances and uncertainties.
