Fabrication of stable photoanode built from ZnO nanosheets in situ decorated with carbon film

In this work, we successfully fabricated a novel stable photoanode, which was built from ZnO nanosheets in situ decorated with carbon film (ZnO/carbon). The thin carbon film, as a passivation layer, can not only improve the photoelectrochemical (PEC) performance, but also significantly depress the photocorrosion of ZnO. Compared with bare ZnO photoanode, the photocurrent density of ZnO/carbon has been increased nearly five times, and its IPCE value can be up to 27% (0.5[Formula: see text]V versus Ag/AgCl). Moreover, the XRD, SEM and TEM data further demonstrate the crystal and microscopic structure of ZnO/carbon in detail.

Synthesis of Li3V2(PO4)3/C for use as the cathode material in lithium ion batteries using polyvinylidene fluoride as the source of carbon

The Li3V2(PO4)3/C cathode, prepared using PVDF as the source of carbon, is covered by a thin carbon film and has an excellent conductivity and electrochemical performance.

Mechanical and Tribological Properties of Carbon Thin Film with Tungsten Interlayer Prepared by Ion Beam Assisted Deposition

Mechanical and tribological properties of the thin carbon film with tungsten interlayer were investigated. The carbon film (130 nm) and the tungsten interlayer (20 nm) were prepared by ion beam assisted deposition (IBAD) method. Both layers were electron beam evaporated and were simultaneously irradiated by the beam of argon (Ar) or nitrogen (N) ions with energy of 700 eV. Mechanical properties of the thin carbon film with tungsten interlayer were investigated by the nanoindentation method. Concerning tribological properties the coefficient of friction was investigated by means of pin on disc tribometer. Phase composition was investigated by X-ray diffraction method (XRD), and bonding characterization of carbon thin film was characterized by Raman spectroscopy.
