O galuega o lo'o iai nei o lo'o lipotia mai ai se tala fou e tasi le la'asaga, fa'akomepiuta lanumeamata mo le tu'ufa'atasiga o le masoa-stabilized palladium nanoparticles (PdNPs) fa'atasi ai ma le fua fa'atatau o le 30-40 nm.O nei vaega sa mautu ma tutusa le lapopoa.I le tulafono o lo'o i ai nei, o le fa'aitiitia o le palladium chloride o lo'o fa'atumauina le malosi o le la na ausia e ala i le fa'aogaina o le citric acid e fai ma sui fa'aitiitiga ma le masoa e fai ma sui fa'apipi'i.Uv-Visible spectroscopy, Transmission Electron Microscopy, Field Emission Gun-Scanning Electron Microscopy, Electron Diffraction Electron diffraction ma Electron dispersive X-ray Na fa'aogaina auala su'esu'e ole spectral e fa'ailoa ai PdNPs fa'apipi'i masoa.O iinei;o lo'o matou lipotia le tu'ufa'atasiga o le masoa ma le citric acid i le tu'ufa'atasiga o PdNPs mo le taimi muamua.O le gaioiga faʻamalosi o nanoparticles synthesized ua siakiina mo Suzuki ma Heck cross coupling reactions.O le gaosiga o oloa na faʻamaonia e le GC.O oloa na faʻamaonia i le faʻaogaina o le GC-MS suʻesuʻega ma faʻaaoga foi le GC ma le fesoasoani o tulaga faʻamaonia.Malosi a le la fesoasoani masoa fa'amautu PdNPs fa'aalia galuega sili i le fa'avaeina o le CC i le va o le aryl halides (I, Br) fa'atasi ma le phenyl boronic acid ma ona mea e maua mai ai.E le gata i lea, o le faʻamalosi na faʻaalia le gaioiga lelei i le faʻaogaina o le faʻaogaina o le faʻaogaina o le CC o le faʻavaeina o aryl halides ma le alkene manogi.O le fa'aogaina o le masoa, citric acid, vai ma le malosi o le la e fa'amatagofie ai le tulafono o lo'o iai nei.
