Dopamine  (DA)  and  uric  acid  (UA)  are  two  of  important bimolecular widely  circulated  in  body blood. Therefore, development of simple and rapid methods for simultaneous determination of them in  routine  analysis  has  a  great  significance  for  many  researchers. Therefore,  for  the  first  time, nanocomposite  of  graphene  (Gr)LaMnO3has  been  utilized  to  fabricate  the  new  ...

This paper reports cadmium sulphide nanoparticles-(CdS NPs)-graphene nanocomposite (CdS-Graphene), prepared by a simple method, in which CdS NPs were anchored/decorated successfully onto graphene sheets. The as-synthesized nanocomposite was characterized using standard characterization techniques. A combination of CdS NPs with the optimal amount of two-dimensional graphene sheets had a profound...

The best electrode performance of metal oxide-graphene nanocomposite material for lithium secondary batteries can be achieved by using the colloidal mixture of layered CoO2 and graphene nanosheets as a precursor. The intervention of layered CoO2 nanosheets in-between graphene nanosheets is fairly effective in optimizing the pore and composite structures of the Co3O4-graphene nanocomposite and a...
