Summary: The current trend in the machining industry is to improve machinability and process performance, making nanofluid the preferred choice. Two critical factors, cooling-lubrication parameters and cutting fluid types, are evaluated to enhance machining efficiency. This study focuses on reinforcing the nanofluid and its injection technique to optimize conditions. The results show that adding surfactant significantly improves stability, reduces removed regions on the workpiece surface, and improves surface roughness and cutting force.

Summary: The current trend in the machining industry is to improve machinability attributes and process performance, making nanofluid an ideal choice. Two critical factors, cooling-lubrication parameters and cutting fluid types, are evaluated to enhance machining efficiency. This study focuses on strengthening the cutting fluid (nanofluid) and its injection technique to achieve optimal conditions. The results demonstrate that the addition of surfactant to the nanofluid significantly improves surface quality, tool wear, and cutting force compared to non-surfactant nanofluid and conventional cutting fluid. The maximum improvement is achieved through the green technique of minimum quantity lubrication (MQL) with specific flow rate, injection pressure, and tool-nozzle gap parameters.

Summary: This study investigates the synergistic effect of aluminum oxide nanoparticles on the efficiency of sodium dodecyl sulfate as an anionic surfactant in surfactant flooding. The results show that the nanoparticles significantly enhance the reduction of interfacial tension between the aqueous phase and crude oil, and reduce the adsorption density of the surfactant onto sandstone rock. Additionally, the addition of nanoparticles improves the oil recovery by approximately 15%.

Summary: This study examines the synergistic effect of sodium dodecyl sulfate (SDS) as an anionic surfactant and aluminum oxide (Al2O3) nanoparticles on the efficiency of surfactant flooding. The results show that the presence of nanoparticles significantly enhances the reduction of interfacial tension between the aqueous phase and crude oil and decreases the adsorption density of SDS onto sandstone rock. The study also finds that there is an optimal concentration of Al2O3 nanoparticles that maximizes oil recovery.

Summary: The study introduces a surface-modified nanoscale polystyrene (NS) as a plugging agent for oil-based drilling fluids, which effectively reduces the surface free energy of NS for enhanced dispersion stability in mineral oil. NS can improve the contact angle of mineral oil on the rock surface, reduce oil imbibition, and maintain rock mechanical stability. Additionally, NS demonstrates thermal resistance, nanoscale dispersion in mineral oil, and significant reduction in permeability plugging apparatus filtration loss and mechanical stability decrease of the rock.

Summary: This paper mainly focuses on the strength and characteristics of hot-formed and cold-formed structural members under different structural arrangements. Both analytical and experimental studies were conducted to analyze the flexural capacity and load-carrying capacity of the built-up beam sections. The results show that the back-to-back connected built-up beam section provides higher flexural capacity, and increasing the bolt spacing enhances the load-carrying capacity of back-to-back sigma section built-up beams.

Summary: The size-dependence of thermally enhanced upconversion luminescence (UCL) for UCNPs has been previously considered to be monotonous. However, this study finds that the monotonic relationship between UCL thermo-enhancement ratio and particle size is broken when the size of UCNPs goes below 7 nm. The breaking of monotonicity is accompanied by a change in the relationship between luminescence properties and particle size and supports the explanation of UCL thermo-enhancement through lattice thermal expansion-induced alleviation of surface quenching.

Summary: Two continuous whipping devices, RS and NAGU, were used to produce aerated food with a 25% (v/v) gas fraction target. The results showed that rotation speed and residence time were key parameters affecting gas incorporation and bubble size. The observation of single bubble deformation and break-up revealed that proteins promote bubble break-up, while non-proteins lead to coalescence and gas plugs.

Summary: Metal matrix composites, made of non-metallic reinforcements in metal matrices, are widely used in industries like aerospace and automotive for their excellent mechanical properties. Aluminum metal matrix composites, reinforced with ceramics like silicon carbide and alumina, are a major division. Despite the challenges in production and machining, the use of lubricants in minimum quantity lubrication and wet modes can reduce tool wear. However, no significant improvement was observed on the average surface roughness values under similar experimental conditions.

Summary: A novel approach to produce a hydrophobic functional surface through rearranging the position of abrasive particles during the grinding process is proposed in this study. Diamond particles were attached in predefined positions using a drilled thin polyethylene mask during the electroplating process, resulting in a structured surface with regular and equal sized scratches. Contact angle tests revealed a 380% improvement in hydrophobicity compared to the original specimen. Additionally, an equation derived from the Cassie-Baxter wettability theory and grinding kinematics showed close agreement with experimental results, validating the accuracy of the novel method.

Summary: This study investigates the effect of annealing temperature on the mechanical properties and formability of brass/low carbon steel/brass composite sheets fabricated by the cold roll bonding process. The results show that the cold roll bonding process significantly increases the tensile strength and hardness of the composite, while decreasing the elongation. However, annealing treatment can moderate these changes and improve the elongation. Microstructural analysis reveals that annealing at 600 degrees C leads to full crystallization in the steel layer and the formation of deep and equiaxial dimples on the fracture surface, indicating improved ductility. Additionally, the forming limit diagram demonstrates that annealing heat treatment enhances the formability of the composite.
