Hello, Dear colleagues,I will be grateful if anyone helps me in determining which of these XPS results is more accurate. All of these results have been published previously in high impact journals.Co 2p:XPS_1 Cobalt Sulfide Nanoflakes Grown on Graphite Foam via solvothermal routeXPS_2 Ball mill assisted synthesis of cobalt–iron sulfide/N-doped carbon XPS_3 graphene nanosheets anchored with homogeneouscobalt sulfide nanoparticles via sol–gel route Thanks
