 Alchemy was developed in Europe within the medieval age and it based the origin of recent chemistry . The brightly shining color and also the virtually excellent chemical immobility of gold has attracted men and girls as an emblem of eternal power and sweetness. it's so cheap that numerous individuals unreal to supply gold unnaturally. Even Newton was deeply concerned within the chemical synthesis of gold . because of this history, gold has long been neglected as part of valuable functions. for instance, gold was regarded to be virtually inactive as a catalyst and was so a lot of less active than metal and Pt . throughout the course of synthesizing mixed oxides of gold with base transition metals, I found in 1982 that once gold was coprecipitated with 3d transition metals and calcined at temperatures on top of 570 K, the mixed oxides exhibit high chemical process activities for CO oxidisation even at a temperature as low as two hundred K . Later, the mixed chemical compounds were proved  by Iijima with a transmission microscopy to be composed of subfigure ultrafine particles of gold connected powerfully to the bottom metal oxide supports . The astonishingly high chemical process activities generated by nanoparticulate gold were introduced collectively of the everyday examples that might demonstrate the good thing about nanoscience and technology
