  • Patent number: 10149862
    Abstract: A facile approach is described to prepare monodisperse Fe3O4 and Co3O4 nanoparticles on chemically reduced graphene oxide (rGO) to form nanocomposites by low temperature solution route and MWI method, respectively. These processes are environmentally friendly and convenient compared with previously reported methods. The synthesized nanocomposites were characterized using x-ray diffraction spectroscopy (XRD), raman spectroscopy, scanning electron microscopy (SEM) measurements and UV/Vis absorption spectroscopy. XRD patterns revealed the high crystalline quality of the nanocomposites. SEM micrographs showed the morphology of the rGO nanosheets decorated by Co3O4 and Fe3O4 nanoparticles. UV/Vis study revealed the formation of Fe3O4/rGO and Co3O4/rGO nanocomposites with characteristics absorption maxima. Finally, preliminary results of using the Fe3O4/rGO and Co3O4/rGO composites for efficient killing of Human hepatocytes cancer (HepG2) cell are reported.

Consequently, the electrode can include an active material layer in which particles of an active material are electrically connected to each other by graphene.

  • Publication number: 20140217330
    Abstract: A metal oxide-carbon composite includes a carbon aerogel with an oxide overcoat. The metal oxide-carbon composite is made by providing a carbon aerogel, immersing the carbon aerogel in a metal oxide sol under a vacuum, raising the carbon aerogel with the metal oxide sol to atmospheric pressure, curing the carbon aerogel with the metal oxide sol at room temperature, and drying the carbon aerogel with the metal oxide sol to produce the metal oxide-carbon composite. The step of providing a carbon aerogel can provide an activated carbon aerogel or provide a carbon aerogel with carbon nanotubes that make the carbon aerogel mechanically robust.

  • Publication number: 20140117290
    Abstract: Epoxidised natural rubber [ENR] based vulcanised-blends with two different types of electrical conductive filler (i.e. conductive grade-carbon black and intrinsically electrical conductive polymer) may be produced respectively by using either internal mechanical mixing method or open milling method or the combination of the two methods. All these ENR based vulcanised-blends show high consistent reversible electrical behaviour under the tensile straining process. They also exhibit useful mechanical property ties with tensile strengths up to 28.0 MPa, elongations at break up to 800.0% and Dunlop rebound resiliencies up to 55.0%. The lower the rebound resilience, the better the damping property and shock absorption ability for the ENR based vulcanised-blends. As a result, these ENR based vulcanised-blends are ideal to be used for manufacturing flexible sensors that may correspond to the tensile straining process.
