Carbon nanofiber (CNF) was prepared by electrospinning using polypropylene and nickel was coated on the CNF by electroless plating. Then, graphene (Gr) was synthesized on the surface of nickel by chemical vapor deposition. After etching nickel, the Gr/CNF was obtained eventually and then used as a working electrode for the determination of levodopa in the presence of uric acid by cyclic voltammetry...
Nickel powders were prepared by the liquid phase reduction method. Using the nickel powders as the template, three-dimensional graphene foam (3D GF) was prepared via chemical vapor deposition (CVD) at high temperature, followed by acid etching. It was transferred onto the indium tin oxide (ITO) glass (3D GF/ITO) and acted as the electrode for the simultaneous determination of dopamine (DA) and uric...
Al2O3 was successfully coated on LiNi0.8Co0.15Al0.05O2 cathode material by a heterogeneous nucleation-and-growth process with a core-shell structure for Li-ion battery. X-ray diffraction (XRD) measurements were used to indicate that the crystal structure of LiNi0.8Co0.15Al0.05O2 had no changes and no impurity phase existed after coating. Scanning electron microscopy (SEM) showed differences of surface...
