Loosening failure of bolted joints often occurs in a vibration environment.This may induce the separation of clamped components and rosy teacup dogwood even result in catastrophic consequences in certain situations.Various anti-loosening bolted connections have been developed and widely applied to prevent loosening.Tightening and fatigue resistance
Combining iron oxide nanoparticles (Fe3O4 NPs) and gold nanoparticles (Au NPs) in one nanostructure is hp pavilion 15-eg1053cl a promising technique for various applications.Fe3O4 NPs have special supermagnetic attributes that allow them to be applied in different areas, and Au NPs stand out in biomaterials due to their oxidation resistance, chemic
