The present disclosure relates to an anode electrode active material for a secondary battery containing nickel cobalt molybdenum oxide, an anode electrode for a secondary battery including the same, a secondary battery including the anode electrode for a secondary battery, and a method for manufacturing the same. The novel anode electrode material for a sodium secondary battery containing nickel cobalt molybdenum oxide according to the present disclosure allows intercalation/deintercalation reaction of sodium ion during charge/discharge and does not undergo significant volume change during the intercalation reaction because structure is maintained stably during repeated charge/discharge. As a result, electrode damage and electric short circuit are decreased and, thus, improved electrochemical characteristics can be achieved in long-life and high-rate capability.

A method of producing a multi-layered functionalised graphene oxide paper, comprises the steps of providing an aqueous suspension of oxidised graphene oxide flakes, size reducing the oxidised graphene oxide flakes in the suspension to provide an aqueous suspension of particulate oxidised graphene oxide having an average particle size of less than 1 μm and drying the aqueous suspension in a vessel to provide a multi-layered graphene oxide material. The multi-layered graphene oxide material is annealed to provide a multi-layered reduced graphene oxide material, before surface grafting functional groups to the surface of the multi-layered reduced graphene oxide material by reacting the material with a functional group precursor in the presence of plasma. The use of a graphene oxide material to treat bone defects, and as an energy storage device, is also described.

In this work, we investigated the blood platelet adhesion and activation of truly superhemophobic surfaces and compared them with that of hemophobic surfaces and hemophilic surfaces. Our analysis indicates that only those superhemophobic surfaces with a robust Cassie-Baxter state display significantly lower platelet adhesion and activation. The understanding gained through this work will lead to the fabrication of improved hemocompatible, superhemophobic medical implants.
