nowdays,  iron  nanoparticles  due  to  their  unique  characteristics  are used  in  all  of  sciences  and  technology.  these  nano  particles  due  to their  electrical, magnetic,  optical  and  catalytic  properties  and  having high  area  and  activity  that  is  promped  by  their  small  size  and most importantly  many  scientists  from  the  entire  world  are  interested  in their  ...

The incorporation of copper species is synthesized  in a silica matrix by the sol-gel method. We have doped copper ions and copper particles using two different copper sources: Cu(NO3)2.3H2O and copper particles chemically synthesized. We can prepare the particles of copper metallic, cuprous and cupric oxide and  compare the synthesis and characterization copper species on the silica matrix.  O...

abstract the aim of this study is laboratory investigation of nitrate reduction in water using fe/cu nano particles. in this regards, nano fe0 (54±4 nm) and fe/cu particles (75±3 nm) was synthesized and characterized by x-ray diffraction pattern (xrd), scanning electron microscope (sem) and transmission electron microscopy (tem) photographs. the effects of coating load of nano-fe0 by cu (0, 5, ...

Nanoparticles have as characteristics super sliding, extreme pressure, self-healing, etc., which can improve the friction reduction and anti-wear performance of sliding components, when used lubricating oil additives. Nano-copper particles a good synergistic effect with other antifriction agents, antioxidants grease additives because their low shear strength grain boundary slip effect, showing ...

Nano-copper sintering is one of new die-attachment and interconnection solutions to realize the wide bandgap semiconductor power electronics packaging with benefits on high temperature, low inductance, thermal resistance cost. Aiming assess high-temperature reliability sintered nano-copper interconnection, this study characterized mechanical properties particles using nanoindentation tests. The...
