After doctoral studies at Queen’s University of Belfast on magneto-optical materials and postdoctoral research on fs direct laser micro-deposition at IESL in Crete, Pagona moved to the University of Ulster in 1998 embarking on a new research programme addressing the synthesis and comprehensive characterisation of diamond like carbon. Currently her group specializes on the fabrication and functionalization of low dimensional carbon based nanomaterials, the characterization of their unique physical and physicochemical properties and the demonstration of these materials in biological sensing and energy areas. The team has made several breakthroughs in the above areas
A recent highlight of the graphene work has been the integration of vertical graphene sheets into a platform, for elucidating the electrocatalytic properties of graphene edges. The work has created a new class of graphene based electrodes for a wide range of applications in the electroanalytical, biosensing, energy storage/conversion sectors that could essentially compete their vertically aligned carbon nanotubes counterparts.The team has also pioneered a simple, low cost and environmentally friendly way to turn common graphite flakes into bulk amounts of either high quality graphene nanosheets or quantum dots by ionic liquid assisted grinding. They have established an international reputation on probing the local atomic environment of carbon based materials by synchrotron light. In a series of papers the details of the interaction of foreign molecules such as nitrogen, oxygen, silicon and chlorine with the graphene lattice have been investigated by synchrotron based spectroscopies (NEXAFS, PEEM, XPS, VB).
