We report the use of a spray pyrolysis method to synthesize high surface area (BET surface area of 139 m2 g-1) self-organized, micron sized urchin-like composites made up of reduced graphene oxide and needle-shaped manganese oxide (rGO-Mn2O3-Mn 3O4). Maximum capacitances of 425 Fg-1 at 5 mV s-1 from a three electrode set up and 133 Fg-1 at a current density of 0.2 Ag-1 were recorded using an asymmetric two electrode set up with graphene as the anode. The composite material also showed a capacitance retention of 83% over 1000 cycles. We attribute this remarkable performance to the high specific surface …

This paper presents a framework which addresses a series of activities defined in Engineering Asset Management (EAM). This framework is proposed to serve as a guideline of organizations when investigating if the status of the EAM system that they have in place is adequate to achieve the intended objectives. It also serves as a guide for researchers in EAM. The framework ensures a holistic approach to EAM in place that it explores the required asset management activities, relationships and mechanisms for achieving the organizational goals. In order to demonstrate the framework, a ‘retroductive’ approach in the context of case study …

In this work fibres and complex three-dimensional scaffolds of a covalently linked graphene-polycaprolactone composite were successfully extruded and printed using a melt extrusion printing system. Fibres with varying diameters and morphologies, as well as complex scaffolds were fabricated using an additive fabrication approach and were characterized. It was found that the addition of graphene improves the mechanical properties of the fibres by over 50% and in vitro cytotoxicity tests showed good biocompatibility indicating a promising material for tissue engineering applications.
