There have been very few studies on the effects of combining two or more techniques sensing performance nanostructured sensors. Cr2O3-functionalized ZnO nanorods were synthesized using carbothermal synthesis involving thermal evaporation a mixture and graphite powders followed by solvothermal process for Cr2O3-functionalization. The ethanol gas-sensing properties multinetworked pristine nanorod sensors under UV illumination examined to determine Cr2O3-ZnO heterostructure formation...
The present study investigates a fatigue property and its microstructural interface geometrical effect on the resistance element welded (REWed) aluminum (Al)/high-strength steel (Fe) lap joint. assembled Al/Fe joints were subjected under strength up to 80% of tensile-shear loads with 0.1 load ratio. As result, an exceptional has been secured inducing base material fracture because there are no noticeable interfacial defects at 10.5 kA welding condition compared assemblies joined 3.5–4.5...
