We demonstrate the spin filtering effect in Co|MgO|TiOx|graphene junctions and a large negative spin polarization in graphene at room temperature. By systematically introducing Ti (TiOx) clusters to the exfoliated few-layer graphene, we confirm that the Ti (TiOx) clusters will increase the charged impurity scattering and lead to a decreased momentum scattering time and an abnormal Gaussian broadening...
Novel pomegranate-like hollow carbon nanoparticles (PLHCNs) were prepared by a dual-template method based on nickel nanoparticles (Ni-NPs) as an active hard template and sodium dodecyl benzene sulfonate (SDBS) as a soft template and pore former. The synergistic effect of Ni-NPs and SDBS imparted PLHCNs with appropriate pore structure, moderate specific surface area (617 m2 g−1), ultrasmall nanocavities...
Graphene has very significant optical and electronic properties, which attract enormous attention. As a unique two-dimensional crystal with one atom thickness, it has high electron and thermal conductivities in addition to flexibility, robustness and impermeability to gases. Its ultra-broad band optical response and excellent non-linear optical properties make it a wonderful material for developing...
Isoelectric focusing was used to separate the different components of fullerenols based on their different electronegativities induced by the surface chemical functionalities and structures. Purified fractions of fullerenols were analyzed and characterized by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The results showed that four fractions of fullerenols could be...
Multifunctional carbon foams with mean pore size smaller than 200μm were prepared by supercritical foaming, in which toluene and mesophase pitch were used as the supercritical agent and carbonaceous precursor, respectively. The supercritical foaming behaviors and nucleation mechanisms were analyzed. According to the composition of mesophase pitch and micrographs of resultant carbon foams, the interface...
