Abstract The tribological characteristics of biodiesel blends containing corn oil and nanoparticles copper oxide titanium dioxide were examined in this study. prepared along with nanopowders are blended 20W-40 lubricant. aim was to explore the potential these as lubricants various mechanical systems. A pin-on-disk equipment used perform tests under different stresses. optimal outcomes achieved incorporation 100 ppm CuO BD20, which reduced coefficient friction by much 80 % decreased wear rate up 75 comparison pure biodiesel. There is also a decrease frictional force for sample BD20 pin temperature minimum BD20. results indicate viability using mixtures TiO 2 eco-friendly diverse industrial applications.

A strong alkaline catalyst, sodium methoxide (CH3ONa), is commonly used to catalyze the transesterification reaction for biodiesel production. Meanwhile, titanium dioxide (TiO2) anatase with a bandgap of 3.2 eV highly competitive photocatalyst after absorption sufficient energy from ultraviolet light. There has been no published report on synergistic catalyst effects CH3ONa and TiO2 further facilitating reaction. Hence, an impregnating method was in this study prepare heterogeneous comprising nanoparticles embedded catalyst. The were first immersed aqueous solution so that could diffuse into interior surfaces porous structure. mixture then calcined temperature range 150 °C 450 4 h produce TiO2/CH3ONa photocatalyst. Various characteristics analyzed determine optimum preparation conditions. Fourier transform infrared spectroscopy spectra revealed peaks appeared wavelength 600 cm−1 1500 cm−1. X-ray diffractometer analysis showed did not alter crystal structure carrier TiO2. At temperatures between 100 800 °C, intermediate or pyrolyzed product detected, as by thermogravimetric analyzer spectra. In addition, about 5~9 wt.% elemental calcium be onto surface FTIR confirmed successful sintering bonding nanoparticles. dispersive spectrometry result filled compound.

Abstract This study investigated the impact of incorporating a CrFeNiTiZn High Entropy Alloy (HEA) into A356 aluminum matrix through friction stir processing (FSP) technique. The HEA, renowned for its compositional complexity and high-performance potential, was incorporated alloy with different weight percent combinations to enhance mechanical tribological characteristics. results revealed refined microstructure characterized by solid solution phases potential intermetallic compound formation due HEA addition A356/2 %Cr2 %Fe2 %Ni2 %Ti2 %Zn composition. Strong interfacial bond strength also observed among reinforcement particles number grains found be about 1820.34 (average grain size is 686 µm) processed composite FSP per square inch at 500 magnifications. exhibited improved tensile (35.70 %) hardness (63.33 after 2 alloy, attributed strengthening effect particles. Furthermore, wear resistance notably enhanced, likely synergistic effects HEA’s inherent modified microstructure.
