Ulster University
CURRICULUM VITAE PAGONA PAPAKONSTANTINOU; BSc Physics, PhD Materials Science, FRSC, Professor, Engineering Research Institute (ERI), Ulster University

Pagona Papakonstantinou has been educated in Greece (BSc (Hons) in Physics from the Aristotle University of Thessaloniki) and Great Britain (MSc in opto-electronics and PhD in Materials Science from Queen’s University Belfast).  Since 2009 is Professor of Advanced Materials at the Engineering Research Institute of Ulster University and specialises in R&D of strategic novel materials and multifunctional hierarchical architectures for  their implementation in health-care, energy and structural sectors. She has carried out research in a wide ranging area, however three main themes can be identified: (i) synthesis of novel carbon and non-carbon based materials and hierarchical architectures employing plasma enhanced CVD and solution based strategies; (ii) investigation of microstructure-electrochemical-mechanical properties relationships and (iii) surface functionalization and characterization the electronic structure of  interfaces using both lab and synchrotron based x-ray spectroscopies. Papakonstantinou has authored over 120 publications and her work has received over 6560 citations, with an H index of 39 (google scholar). Her work has attracted international recognition, as exemplified the following honours: (i) invited Research Fellowship from the Royal Society of Chemistry, RSC (2014) through ‘Leaders in the Field’ scheme for her significant contributions to nanoscience and nanomaterials; (ii) a Distinguished Research Fellowship from Ulster University (2003) and  (iii) a Royal Academy of Engineering (RAE)/Leverhulme Trust Senior Research Fellowship (2012). Papakonstantinou holds a portfolio of 5 patents applications as Lead inventor and three Proof of Concept (funded by INEVSET NI) projects as Lead Investigator, in the area of graphene and other 2D materials. A granted patented technique (US 20140044968) on scalable synthesis of graphene and 2D materials has been licensed to 2-DTech/Versarien Ltd, and has generated new business. Papakonstantinou  is reguraly invited to serve and chair panels in numerous national and international funding agencies and organisations including EPSRC, European Commission and  Helmholtz-Zentrum Berlin Light Source.

内容摘要

2D crystals have emerged as the new paradigm of materials with enormous potential in   electrocatalysis arena  ranging from energy generation and storage to biosensing applications. In this talk I shall present our recent contributions in these fields. 
I will describe new results on addressing key challenges involved in optimizing catalytic performance in transition metal dichalcogenides (TMD). In particular, I will describe the important role of solvents and  electrochemical activation on hydrogen evolution reaction (HER) characteristics such as Tafel slope and current densities of TMDs[1] . I will summarize our important developments in synthesis of 2D materials (e.g. Bi, MoO3) using ionic liquid assisted grinding exfoliation and size selection of exfoliated layers using sequential centrifugation[2,3]. The hidden role of metal impurities on nitrogen doped graphene for influencing the oxygen reduction reaction performance will also be presented. Finally, towards the application of 2D materials in biosensing I will present our recent advances on the design and fabrication of a novel chronocoulometric sensor based on semiconducting MoS2 nanosheets  decorated with a controlled density of monodispersed small gold nanoparticles for the highly sensitive detection of miRNA-21[4]. The sensor achieves an impressive detection limit of 100 aM,  which is   2 orders of magnitude  lower than that of bare gold electrode. The underlying physical principles, as well as key challenges associated with the optimization of sensor on achieving  the low detection limit will be explained.
